Q

canada as a beef exporter

A
  • Canada is a small player on the world
    stage in terms of overall production
  • However, Canada is a fairly significant
    exporter of grain finished, high-quality
    beef
  • Exporting beef is an important aspect of
    this industry in Canada, we cant eat all the beef we produce
    -USA is our largest export

    – BSE effect!!
  • Dropping steadily since then now at 11
    million head
  • The industry has been in a period of
    significant contraction
  • Beef cow numbers are at 3.46 million

Q

western canada concentration of beef

A
  • Beef production is concentrated in
    Western Canada
  • > 80% of beef cow herd in 3 prairie
    provinces
  • Alberta dominates fed cattle production
    by feeding 2/3 of the cattle destined for
    slaughter
  • Alberta would be ranked 4th for fed
    cattle production when compared to
    U.S.

Q

industry segmentation

A

– Cow calf industry which is predominated
by small herds
– Intermediate stages of backgrounding and
stocker operations
– Feedlot industry which is predominated by
larger commercial operations (primarily
southern Alberta)
-three phases are: cow-calf, background/ stocker, feedlot

Q

backgrounder

A
  • Feed cattle for growth prior to going into a
    feedlot for finishing
  • May occur on original cow-calf ranch or
    may involve a change in ownership
  • Backgrounding involves feeding calves for
    a shorter period for moderate weight gain
    (1 kg/day)
  • Medium-low energy rations (forage based)

Q

stocker

A
  • Stocker operations utilize forage and crop
    residues
  • Grain stubble, wheat pasture, grass
  • Often will involve utilized pasture on
    calves that have been backgrounded the
    previous winter
  • Will be sold as yearlings for a short period
    of finishing in the feedlot

Q

feedlot

A
  • Fed in pens where harvested feed is
    brought to them
  • High energy diet (barley & barley silage)
  • Cattle may be 12-24 months of age by
    time of slaughter
    -calves fed for 180-280 days, yearlings 100-180 days
    -* Target slaughter weight of 1250-1550 lb
    (live) for steers
  • High energy, low roughage diets to
    optimize growth
    -most in AB

Q

factors leading to the cattle price right now

A
  • Contraction of industry has led to fairly high
    prices for cow-calf industry for several years
  • Drought of 2021-2023 has had a major impact
    on cow numbers
  • Weaned calf prices have seen historic highs due
    to high demand and low volume
  • Prices quoted in $/cwt live weight
  • Feedlot profitability is tied to grain prices,
    Canadian dollar and cattle prices
    – This can be highly volatile with low margins

Q

normal stages of calving

A

 Stage 1
 3 hours-72 hours (cows<heifers)
 Ligaments of pelvis relax
 Cervix, vagina dilate
 Cervical mucous plug released
 Cow separates from herd
 Tail raised, back arched, may start to strain

 Stage 2
◦ Appearance of water bag
◦ Expulsion of calf through the birth canal
◦ 30 minutes to three hours (cows<heifers)

 Stage 3
◦ Expulsion of fetal membranes
◦ Usually expelled within a few hours of birth
◦ Involution of uterus may take up to 40 days

Q

when to help with dystocias

A

 Cow actively strains for 40 minutes and no progress is made
 90 minutes have passed since the first waterbag appeared
 The legs emerge with the sole of the hooves pointing up
 The head or tail only emerges
 A cow has demonstrated greater than 5-6 hours of anxiety, eg: walking about, tail extended, apparently looking for something

Q

hypothermia

A

 A calf within first 2-3 hours is unable to regulate body temp very well
 Even a normal calf can become hypothermic quickly
 Chilled calves will not be able to get up, suckle and make use of colostrum
-calves less then 35 degrees C. cold body, no suck reflex. normal is 37.8 C
 Tube with 1-2 litres of warm colostrum
 Place in warm room or “hot box”
 Hot water baths are essential for calves less
than 26 C (80 F)
 Warm fluids IV,

colostrum management

A

 A calf needs a minimum of 1-2 litres of colostrum within 4 hours of birth
 Beef cow colostrum contains 150 g of IgG/litre on average
Gut closure begins at 6 hours and
continues until 24-36 hours
 Calves need 80-150 g of
immunoglobulin (1-2 litres of colostrum)
 Normal calves will drink between 1 to 2 litres/feeding

calf management at "Turn out"
* Clostridial Vaccines (7or 8 way) * Initial Histophilus somnus vaccination (optional) * Other respiratory vaccines (optional): * Mannheimia hemolytica, P. multocida * IBR/PI3/BVD/BRSV * (intranasal vaccines as option) * Dehorning and castration if required * Growth implant for steer calves (heifer calves?) * Vitamin E/Selenium injection
26
*Vaccinations of Cows prior to breeding season
Modified live IBR/PI3, BVD, BRSV vaccine * Campylobacter fetus (Vibrio) (optional) * Leptospirosis (optional) * Histophilus somnus (optional) * Clostridial vaccine booster for heifers! (cows?)
27
Management of Cow Herd Prior to Breeding Season
* Fly Tags * Body condition score cows * Weigh heifers for assessment of target weights * Reproductive tract scoring and pelvic measurements in heifers? * Estrous synchronization for heifers? * Bull evaluations +/- Trichomoniasis testing
28
Objectives of Reproductive Management
*High percentage of cows pregnant *Maximize weaning weights *Uniform calf crop: short breeding season * 42-45 days for heifers * 63 days for cows *Breed heifers to calve as two year olds *One calf/cow/yr over 3-5 reproductive lifetime
29
gestation legnth and pregnancy breeding
* Fixed gestation length (282 days): Cows must conceive within 85 days of calving * Delay in first estrus due to suckling * Suckled beef cows do not begin estrous cycles for 40-60 days post calving * Conception rate of 60% - 70% maximum
30
flushing
-Feed cows increased energy rations so that they are gaining weight just prior to breeding season *Cows in positive energy balance are more likely to conceive *Cow with above average weight gains on pasture were 2.16 times more likely to be pregnant
31
Management Program for Heifers
*Raise heifers to reach target weights * 65% of mature weight at breeding * 85% of mature weight at calving * Winter heifers separately * Feed appropriate ration * Select heifers from early calvers -15-20% cow herd replaced each year -replacements must be calving in first period or earlier!! (100 day PPI)
32
first time heifers breeding interval
* The time from calving to cycling (post partum interval) lasts 80-100 days for first calf heifers In order for first calf heifers to be cycling at the start of the next breeding season: * Heifers need to calve 0-20 days ahead of the cows, 30 days for momentum!! -Therefore heifers need to be cycling by 12-13.7 months of age - (Mean age of puberty is 11.5-14 months)
33
bulls
bull: cow ratio: yearlings 15-20 2 year olds: 20-30 3+ years: 30-40 -max scrotal surcumference met by 4-6 yr of age *By 12-14 months of age, bulls should have reached a minimum scrotal circumference (32 cm) -Scrotal circumference is correlated to age of puberty of female progeny
34
culling cows
* Most cows are not in herd for longer than 11 years * Average is 5-6 calves in cow’s lifetime * Minimum of 15% of cows are usually replaced yearly * Primary reason = reproductive failure * Other reasons: age, cancer eye, udder problems
35
overwintering beef cows
-#1 expense -extending grazing szn can lower. -separate groups based on BCS * Feed analysis for least cost rations * Methods of feeding may affect wastage * Target BCS of 2.5-3 at time of calving
36
Increasing Profit in Cow-Calf Herds
* Increasing lbs of calf weaned/cow exposed to bull * Biological productivity * Reproduction/calf survival (calves weaned/cow) * Calf growth (weaning weights) * Increasing market value of calves weaned * Calf price/lb * Reducing expenses of maintaining cow herd * Lowering cow costs * ***Feed costs***
37
5 Ways Low-Cost Producers Reduce Costs
* Reduce supplemental feed costs * Rotational grazing and pasture management * Right genetics * Reduce labour costs * Strong herd health program
38
Monitoring Productivity in the Cow-Calf Herd gold indicators
1 growth: weaning weights, sale weights. 2 open cows: open rate %, usually 7% 3 Length of calving period, usually 63 days 4 death loss: usually >4%
39
Calf crop %
* Overall measure of biological productivity * Reflects management of reproduction and calf mortality * Requires only simple inventories * Target of 85% -lbs calf crop %
40
Weaning Weights
* Can be used as a measure of a cow’s producing ability * Can also be used as a measure of the sire’s genetic potential * However can be misleading: * Bull calves > heifer calves * Calves from cows > Calves from heifers * Older calves > younger calves
41
Adjusted Weaning Weights
-Simplest form simply adjusts for age of calves * Estimates a weaning weight as if all calves were weaned at 200 or 205 days of age * ADG = (Weaning Wt - Birth Wt)/Age of calf * 200 day Adjusted Wt = ADG x 200 + Birth Wt. * “Artificial” number * Give “unfair” advantage to late calving cows -can adjust sex
42
DNA testing
-linked to production records! * Present Cost is $12-$20/sample * Generally a parentage panel using 120 SNPS to determine which bull sired a calf * Tests can be done on blood or hair follicles * Genetic tests can be done to identify breed composition for breeding decisions in commercial cross-bred herds to improve hybrid vigour
43
viral vaccines killed
*IBR, PI3, BRSV, BVD 1 & 2 * Triangle 5 (Boehringer) * Vira-Shield 6 (Elanco) * Cattlemaster Gold FP 5 (Zoetis)
44
Respiratory Bacterial Vaccines
* Mannheimia hemolytica, Pasteurella multocida *Can be in combination with virals
45
calving/ branding protocols
* Calving * Weigh and tag calves * Vitamin E/Selenium * Branding (Pasture Turnout) * 7-way Clostridial +/- H. Somnus * Mannheimia hemolytica* * IBR, BRSV, PI3, BVD vaccine* * Intranasal vaccines vs Injectable* * Growth implant * Castrate * Dehorn
46
weaning calves fall vaccines
IBR/PI3/BVD/BRSV (modified live virus) * *Pasteurella multocida/Mannheimia hemolytica * 7-way Clostridial +/- H. somnus * Pour on endectocide (Ivomec, Cydectin, Dectomax) * Weigh for weaning weights
47
pregnancy exam
* Bred Heifers: * Pour-on endectocide * 1st dose of scour vaccine (E coli, Rota, Corona) * Mature Cows: * Pour-on endectocide or other form of lice control * Identify culls * Open * Bad udders * Temperament * Feet and legs
48
pre calving vaccination
* Cows * Scour vaccine (Rota/Corona virus/E coli) * Vitamin AD? (Could be included in ration if appropriate?) * Heifers * 2nd dose of scour vaccine * Vitamin AD?
49
3 parts of feedlot management
*Fiscal Strategy: facillites, land for manure, livestock financing, operating capital *Livestock Inventory Control *Technical Aspects of Feeding Cattle
50
What determines the price of a weaned calf?
* Demand! * Gender: * Price for male calves > Price for female calves * Due to feed efficiency advantage * Weight: * Lighter calves tend to cost more $/cwt (Weight breaks) * However, despite these price differences the heavier calf is still worth more total $ * Quality: * Castration status – Steers > Bulls * Horns, frozen ears, body condition, previous vaccinations etc. * Breed type? * Size of group: * Cow-calf producer takes calves to auction market and are those calves are sorted into sales lots by gender, weight and breed type * If an owner brings a large group of uniform calves and these can be sold together as a large group because they are all the same weight -small 2-10 groups common, lower price
51
What is “yardage”?
* Daily non-feed costs not associated with ownership of cattle * Fixed costs – taxes, insurance, depreciation on facilities * Non-feed operating costs – fuel, utilities, office, repairs, labor etc. * Think of it as the “hotel” charges for a feedlot to operate * Typically charged as $/head/day * Feed costs, medicine/vaccine costs, bedding costs are often charged separately or in addition to yardage
52
risk aversion in feelots
* Feedlot must continue to operate even when profit can’t be projected * Some strategies available to mitigate risk of losses: 1. Increasing the custom feeding proportion of cattle 2. Forward contracting to packer 3. Forward contracting grain prices 4. Hedging – using commodity futures on Chicago Mercantile Exchange
53
step up rations
* A simple solution for dealing with many types of cattle and feed sources etc. * Series of rations (8-10) formulated to specific nutrient requirements * Consistent increase in energy content * Each step up = approximate substitution of 10% grain for 10% silage * Natural progression of energy levels * Allows adaptation of rumen organisms * 3-5 days minimum at each step * Progress to 85% concentrate finishing ration * Can predict performance based on energy/protein level * Can accommodate least cost formulation * Simple enough for day to day application
54
Management of Step-Up Rations
-Cattle are fed “ad-libitum” * Get cattle on full feed, keep them there and avoid rumen acidosis * Individual at feedlot designated as “bunk-reader” * Evaluates amount of feed consumed and gives instructions for daily feeding * Looks at each bunk early in the morning * “slick bunk” – no feed left over at all * Makes decisions regarding what should be fed * Amount to be fed and which ration
55
processing at feedlot
* Should be done as quickly as possible after arrival 12-24 hrs, delays can lead to disease * Processing protocols will be “risk class specific” and “feedlot specific” * The amount of time it takes to “fill” a pen will affect the risk * Slower fill = greater risk * Identification * Vaccinations: IBR/PI3/BVD/BRSV Modified live vaccines * Mannheimia hemolytica * Histophilus somnus * Clostridial bacterin * Early Treatment/Prevention of BRD – “Metaphylaxis” * Parasite Control Products * Implanting * Castration/Dehorning * Quality Assurance * Injection sites/changing needles/ withdrawal times etc.
56
Animal Health Issues in Feedlot Cattle
* Three major categories of health issues: * Bovine Respiratory Disease: Mostly occurs early in the feeding period * Lameness: Can occur throughout feeding period dependent on cause * Nutritional-related diseases (bloat, acidosis: Mostly occurs later in the feeding period
57
Bovine respiratory disease
* Most important disease concern in feedlot cattle!!! * Cattle are often grouped into “risk categories” based on their “risk factors” * Weaning * Age/weight (younger/lighter = higher risk) * Mixing – auction market vs ranch direct * Transportation * Weather * Gender * Vaccination history * Previous exposure to bunks and feed * Other management factors: castration, preg
58
Some basics of BRD
* Morbidity and mortality are dependent on the combination of risk factors present * Morbidity peaks within the first 7-10 days for auction market calves * Morbidity can approach 35-50% * Case fatality is 5-10% * Many calves arrive at the feedlot already incubating disease
59
BRD management solutions
-vaccination at time of arrival: reduces disease it peaks first 7-10 days. -prevaccination: eduction in disease but doesn’t mitigate all other risk factors * There are specific sales and programs for pre-vaccinated calves -Preconditioning: * A step beyond pre-vaccination, preconditioned calves are: * Weaned for a minimum of 45 days prior to sale or shipmen * Cow-calf producer benefits from increased sale weight and a premium price * Preconditioning programs were much more commonplace in the 80’s and 90’s * Challenges included: * low numbers of pre-conditioned calves available * Price premiums not always enough for cow-calf producer * Purchase price vs BRD risk dilemma
60
Metaphylaxis
* Administration of an injectable long acting antimicrobial to control BRD upon arrival * Provides treatment of early cases already incubating disease * Provides prophylaxis to cases that may develop in the next few days -Many antimicrobials have label claims for metaphylaxis * Long acting macrolides= Tulathromycin (Draxxin) * Major economic and animal welfare benefit in terms of close to 50% reduction in treatments and significant drops in mortality * Antimicrobial use and antimicrobial resistance of pathogens are the concerns that are often raised
61
Factors in Choosing Metaphylaxis
Expected disease risk (High risk, ultra high risk calves) * Risk tolerance of the owner: For disease, death and chronics * Product efficacy based on clinical trial data * Labour availability and skill * Cost of treatment and cost of mortality * Cost of the metaphylaxis program
62
toe-tip necrosis
* Unknown cause * Occasionally occurs in outbreaks of feedlot calves from one source farm or auction yard * Often severely lame after arrival at feedyard * May be simply due to severe abrasion of toe during handling * Treatment is unrewarding= culled animals Primarily hind feet affected * Infection usually with environmental bacteria (E. coli, Trueperella pyogenes) * More common in “excitable or wild” animals * Excessive wear on apical white line at toe-tip * Ascending infection
63
Nutritional Diseases and Grain fed cattle
* Finishing rations can often contain close to 90% grain * If not managed well, you can create significant health issues because of acidosis * Moving cattle to quickly up a step-up program * Delivering wrong ration to cattle * Failing to keep feed available at all times to cattle * Liver abscesses, Post-venal caval thrombosis, laminitis, mycotic rumenitis are all potential sequelae to rumen acidosis * Ionophores are an important additive that helps with the management of bloat and acidosis
64
Ionophores
-very wide spread use in almost all feedlot rations * They effect the cell membranes of specific rumen microbes and change the microbial flora of the rumen * ex. Rumensin (monensin) * No prescription required if fed at label dosage and not in combination with other products EFFECTS: * Decrease feed intake (3%) * Changes the protozoa population of the rumen * Improve F/G & Improved ADG (2% - 7%)***** Increase propionate * Reduce acetate, methane, hydrogen ion and lactate production * Slower rate of food passage * Reduced protein degradation in the rumen * Aids in the control of coccidiosis*** * Reduces the incidence of bloat***
65
Hormone Feed Additives
* Melengestrol Acetate (MGA Premix) * MGA - 125 X progesterone activity: -PREVENTS ESTRUS * Stabilizes follicles on the ovary * Reduces plasma cortisol * Metabolized to an androgen * ADG increased & F/G improved*** * Used in feedlot heifers to prevent estrus * Occasionally used to synchronize estrus in breeding animals * Not approved for concurrent use with hormone implants * 24 hour withdrawal prior to slaughter
66
Antimicrobials as Feed Additives
- used over 40 yrs. Antibiotics can cause significant changes in rumen flora resulting in growth benefits as well * However, growth promotion claims are all ELIMINATED * Antimicrobial resistance concerns are becoming more significant! * All antimicrobials in feed now require a veterinary feed prescription! * Primary use in feedlot cattle would be antibiotics in feed to prevent liver abscesses -ones used: tylosin, choletetracycline, oxytetra. * Chlortetracycline + sulfamethazine: * Prevention of foot rot * Reduction of bloat * Maintenance of weight gains -some tetras at high doses prevent histopholis or resp disease
67
Tylosin and Liver Abscesses
* 40-70% reduction in abscesses * Improved ADG by 2.1% * Improved feed efficiency by 2.6%
68
Growth Promotants b agonists
Beta Agonists: * Clenbuterol (illegal)- Not used in beef industry * Ractopamine: Optaflexx, Actogain 100, Ractopamine 100 * True repartitioning agents: * Orally active * Reduce carcass lipid 15%- 40% * Cattle close to market weight would typically become less efficient as they produce less muscle and more fat * Beta-agonists increase weight gain, ribeye area, total red meat yield
69
What do Beta Agonists do?
* Repartitioning agents*** * Alter body tissue deposition: Increase protein and decrease fat ** * Direct mode of action * Chronic exposure to beta-agonists causes receptor desensitization * Therefore these are added to feed at end of feeding period for short period of time (30 days) * Responses are not permanent!: * Zilmax withdrawal should not exceed 10 days * Optaflexx (24-48 hour withdrawal is optimal
70
hormonal growth implants
* Drug delivery system: ▪ Compressed tablets or pellets ▪ 60% - 80% drug (hormone) lactose, cholesterol, polyethylene glycol. -low oral BV, slow release, in an inedible part of animal. safe -two catagorites are: estrogenic or androgenic
71
implant types
ESTROGENIC * Estradiol -17 Beta * Estradiol Benzoate * ZeranoL: ralgro** produced from zeralonone a product of Fusarium spp. of fungus. slightly less anabolic, estrogenic, and dose not bind to muscle tissue like estrogen. USED IN EITHER SEX ANDROGENIC * Testosterone * Trenbolone Acetate * Progesterone
72
mode of action different growth implant hormones
-ZERANOL (ralrow) and estrogen do the same mode of actions * Increase Growth Hormone * Increase Somatomedins * Increase Insulin * Reduce Cortisol -ANDROGEN: *Increase somatomedins *Increase calpistatin *Increase mitosis *Increase structural and enzymatic proteins *Reduce cortisol *Reduce thyroxin
73
Buller Steer Syndrome
* Behavioural trait where steers are persistently ridden by penmates * Ridden animal is referred to as a “buller” * Animals doing the riding are referred to as “riders” * Bullers become exhausted, show loss of hair, swelling and trauma on rump and tail head, suffer severe musculoskeletal injuries * Usual treatment is simply removing the animal from the pen and placing it in a convalescent pen * Can sometimes be re-introduced
74
Implant Effects on Behaviour
Bullers *1%-6% incidence common in US feedlots *Implants involved TBA > Estradiol > Zeranol > No implant *“Stacking” implants – re-implanting too soon after previous implant implant problems could contribute: * Riders: * crushed implants * separated implants * bunched implants * implants too close to the head * Bullers: * missing implants * partial implants * implants in the cartilage * walled off implants * abscessed implants
75
bull steer syndrome stats
2-4% incidence common in feedlots (up to 11%) * More common in larger pens (social dominance?) * More common early in feeding period or after mixing * More common in cattle that are implanted with androgenic implants * Bullers are 2.5 times more likely to get sick * Bullers are 3.2 times more likely to die * Economic losses estimated at $23.68 U.S. per buller
76
Beef Cattle and GHG Emissions 3 ways
-carbon dioxide: burning fossil fuels, crop porduction ect. -methane: in animal and in manure, 5% emmisions. fooddigestion in the GI tract is the largest contributor 60% methane is more potent than CO2 but broken down faster -nitrous oxode: 25% total emissions from canadian beef. dont want excess protien.
77
cost of gain
-costs associated with feeding calf until it reaches slaughter weight -include: cost of feeder cattle, feed costs, health costs, yardage, freight, bedding, interest. -the sum of these costs/ total projected weight gain = COST OF GAIN COG
78
On the rail
* Price paid on a carcass basis
79
grid pricing
* Packers may buy cattle on a carcass basis with bonuses and penalties based on carcass characteristics such as quality grade, marbling score etc.
80
custom feeding
* Custom Feeding provides a “guaranteed” cash flow for the feedlot owner * Custom Feeding lowers Risk compared to ownership -two options: 1. Investing or owning a group of cattle 2. Feeding a group of cattle for other investors/customers -customer owns cattle, takes risk on market, morbidity and mortality. feedlot charges. when marketed to packer the customer gets a cheque.
