Cattle Breeds
- two types of cattle Zebu and Taurine
- 1000+ breeds
- Taurine and Zebu interbreed to create fertile offspring
- Zebu influenced breeds are more heat tolerant
- Taurine influence breeds are more cold tolerant
Where is social learning prominent in sheep and goats?
- resource locations
- shelter locations
Female Mating and Sexual Behavior in Goats and Sheep
- seasonally polyestrous
- > exception is tropical breeds
- females drive sexual activity
- > influenced by day length because they are short day breeders
- > mate in the fall
- > lamb, or kidding occurs in the spring
Factors That Will Affect the Quantity and Quality of Maternal Care
- Maternal Experience
- inexperienced mothers:
- > are slower to start licking their offspring after birth
- > are more disturbed by the activity of their newborn
- > may butt the newborn, or move away when it tries to suckle, but this lasts for a short time - Environmental Factors
- low nutrition of mother during gestation - Temperament and Breed
- nervous or fearful mothers
Foraging and Feeding Behaviors in Sheep
- Sheep prefer grazing
- > Consume Grasses and legumes
Goat and Sheep Social Recognition Cues
- Visual and olfactory
- Sheep can recognize familiars in photos
- Can recognize up to at least 50 individuals
- Recognition lasts for up to 2 years
Things that are critical when people are dealing with pigs
- because they generalize their experience with humans at large, when dealing with pigs it is critical to act:
1. Calmly
2. Consistently
3. Positively
Female Cattle Mating and Sexual Behavior
- They are Polyestrous, or can breed all 12 months
- > There are group calving dates
- At about 9 months of age will have their first estrus which is a 21 day cycle
- Standing heat, or receptive phase will last about 12 hours
- > Allows bull to mount
- Cattle also show Female-female mounting which indicates that the cow is coming into heat
- > Can also attract bulls
- Females often mate with several bulls
Neonatal Mortality in Goats and Sheep
- 3 to 40% neonatal mortality
- Caused by:
- > birth trauma
- > poor maternal and neonatal bond
Effects of Restricted Foraging Behavior in Horses
- Stabling, or Concentrate Feeding Methods have negative effects
- Causes a physiological issue because there is a reduction in saliva production
- > This results in lowered minerals in gut, lowered bicarbonates in gut, effects the gut pH and effects the microflora
- > All of this can cause colic
- Can also cause behavioral problems such as crib-biting and wood-chewing
General Sheep and Goat Social Behavior
- Highly social, or gregarious
- follower species
- in the wild, generally live in small to moderate group sizes
- females and juveniles live together
- males live together and have an overlapping range with females
- generally stay on the home range
Cattle Purposes in Developing and Industrialized Countries
- Food production
- > Meat and milk - Draft animals
- Maintain grasslands
- Multi-purpose breeds
- > Adapted to local climate
- > specialized breeds dominate markets
Bull Group Structure Aggression Behaviors
- threat displays are more elaborate
- More prominent in intact males
- Include vocalizations, pawing, rubbing the head on the ground and posturing
Stallions Social Behavior in Natural Living Environments
- Protective and intervention behavior towards their breeding mares
- Live with groups of mares (harems) and their immature offspring
- There are exceptions such as occasional monogamy and the allowance of younger second stallion to aid in defense of the harem
- Some all male bands may form which indicates that they are more cooperative than normally recognized, but a clear dominance hierarchy exists especially during short resources
General Cattle Care of Offspring and Nursing
- Cows are considered Hider species and will leave the calf behind when foraging after parturition
- calves suckle within hours of birth to receive the colostrum
- fostering also occurs
Rhythms when cattle are in a Freestall Barn
- Less synchronized lying and feeding behaviors when kept in freestall barns
- Generally spread feeding and resting activity across a 24 hour period
- They found that feed delivery to bunks will cause an 82% increase in feeding within the first hour compared to a 26% decrease in feeding within the first hour after returning from the milking parlor
Ancestral Wild Horse
- social herbivore
- survival depended on:
1. Grasslands
2. Vigilance
3. Size
4. Speed - Domestication Benefits:
1. Power
2. Transportation
3. Food
4. By products - glue
- hides for leather
Mating Behaviors in Wild and Domestic Boars
- Wild Boars
- mark their presence by leaving saliva on tree trunks and frequently wallowing - Domestic Boars
- will court proreceptive females by approaching them, short grunting, champ their jaws while salivating and may urinate
- If the sow stands firm the male will sniff the sows head and anogenital region, nudge her, and mount her
- > ejaculations last several minutes
The Modern Horse In Comparison to the Ancestral Wild Horse
- sets up a dichotomy with the phylogeny of its ancestry
- the ancestral phylogeny of the horse still underpins the essence of its behavior and failure to meet the behavioral needs has led to industrial horse management issues
- > These issues include behavioral issues associated with chronic frustration and digestive issues associated with diets that are not well suited to the function of their digestive tract
Foraging and Grazing In Horse’s
- Majority of a horse’s time is dependent on the forage availability and quality
- Moves short distances frequently
- When grazing a horse moves around foraging for between 50-70% of the time
- Will take over 10,000 paces per day
- Samples patches of forages
- takes about 30,000 bites per day
- takes about 60,000 chews per day
What are the consequences of Forced weaning in Sheep and Goats?
- Forced Weaning disrupts:
1. Learning and social development
2. Induces stress in both the mother and offspring
Cattle Group Structure Dominant-Subordinate Affiliations
- Affiliations are determined by positive (affiliative) interactions, and aggressive interactions
- Aggressive interactions decline with familiarity
- These Relationships can affect resource access to water, food, lying space, shelter space and breeding opportunities
- Individual characteristics such as body size and horns can influence social success
Weaning in Beef Calves
- about 6 months
- Dam and milk removed at the same time
- > increased stress
- Dam and calf vocalize, there is excess pacing, and reduced grazing, or feeding
- Two step process can reduce effects
- > Ring in calf nose first
- > Separate several days later
Feral or Wild Cattle Behavior
- Are in groups of cows and calves
- Groups of bulls form separate groups to defend a territory and intermittently interact with cows
- Chirikof Island Cattle
- > wild cattle since the 1800s
