third
28
goats known for being
curious, agile, good climbers and balancers
29
do they display more or less herding behaviour than sheep
less
30
when did goats arrive in aus
first fleet 1788
31
why are goats farmed in aus
meat, fiber, dairy
32
feral goats
- 2.3 million in aus
- compete for feed, damage landscape, biodiversity, waterways and equipment
- BUT also foundation of rangeland goat meat industry
33
ideal grazing habitat for goats
- semi-arid rangeland after rain
- combo or herbaceous shrub and tree forage
34
why do goats do so well in semi- arid regions
- greater diversity of diet, able to digest low quality roughages
- less effected by some anti-nutritional compounds
- longer rumen retention times
- more cellulolytic bacteria in rumen
- greater nitrogen recycling to the rumen
35
what are goats very susceptible to
ruminal acidosis
36
goats preference for browse
reduces worm burdens:
leaves are too high for worm larva to reach without tying, and tannins can inhibit worms in digestive system
37
true or false; although aus is relatively small producer of goats it is largest exporter of goat meat in the world
true
38
where does 90% of goat meat production come from in aus
extensively managed rangeland properties
39
where are major export markets
usa and Taiwan
- not really cooked in aus so limits many consumer markets
40
2 other uses for goats other than production
companion and weed control
41
fibre goat breads

- derived from feral goats
- major source of goat meat
- highly adapted to surive in low rainfall regions
- low input farming systems (extensive)
- can produce some cashmere fleece
- mature weight 45-80 kg
46
kalahari red goats
- meat and milk
- originated from kalahari desert in south africa
- colour is camouflage from predators
- hardiness and mobility suited to harsh conditions

52
how much will purebred cashmeres goats yield
300 g per year, usually shear once per year
53
cashmere goat
- produce good quality meat too

- good mothering
- very fine 12-18 uM
54
cashmere growth is
daylight sensitive; initiated in dec (longest day) and stops and sheds from june onwards
55
growth of cashmere is not responsive to
level of nutrition (unlike wool)
56
what is the best type of FIBRE goat for weed control programs
cashmere due to shorter fleeces

66
shearing
- usually done w goat standing on its head restrained in some form of head bail
- done just before kidding (typically in aug) and then again 6 months later
67
weaning of kids
- about 4 months
- for boer goats kids weaning would be when they are about 22-24 kg of body weight
68
hoof trimming
paring excess hoof of adult goats is usually required where goats are intensively managed and on soft soils
69
castration
should be done as early as is practically possible (before 2-3 months of age to reduce stress on the kids- either rubber (elastrator) rings, burdizzos or surgical catsration techniques
70
goat fencing
- 5 wire, electric is best, well strained bottom wire
- remember goats are great climbers
- goats do not tend to jump fences
- combo of standard fence plus electric fence works well
- should be designed to keep predators out
71
goat behaviour and approaches to handling
- goats are intelligent, naturally curious
- like sheep, goats exhibit flocking and following behaviour
- however goats will split from the herd, and the herd will scatter, much more readily than sheep
- mustering goats and moving them to and through a goat handling facility must be achieved w minimum stress on the stock and the operator
- different to mustering and handling sheep
- goats respond positively when shown where you want them to go
- goats trainable
- goats more at risk from handling stress
- dog use is generally kept to a minimum when handling goats in a yard
72
estimating age by dentition

common in high rainfall regions or on irrigates pastures where stocking rates are high and sheep are run on same properties as goats
76
drenches (anthelmintics)
duration of activity is much less in goats compared to sheep due to their different metabolism
77
lice infestation
common in cooler months in goats in poor body condition w long hair-coat and where stocking rates are high
78
urinary blockages
common in castrated pet male goats
79
abortion rates
5%
80

occurs in last 6 weeks of pregnancy when does graze poor quality pasture and are suddenly exposed to cold rainy conditions
81
clostridial diseases
tetanus (often associated w some form of wound) and pulpy kidney (associated w anything that causes a slowing of motility of the small intestine ex the sudden intake of excessive amounts of grain)
82
when are breeding goats vaccinated against clostridial disease
4-6 weeks prior to kidding this will optimize the development of maternal antibody in colostrum to protect her kids in early life
83
foot rot
infectious disease that infects the soft tissue between the claws (hooves) it is the same disease that occurs in sheep
84
minimum 3vax vaccines
6vax vaccines additional 3

- very few registered APVMA aus pesticides and vet med authority for goats
- require different dose to sheep
- misused chem resulting in meat residues would jeopardize export industry
86
lice treatment/ control
- limited chemicals registered for goats
- set the dose rate for the heaviest goat in the group according to label instructions
- use the correct application gun and ensure that it is delivering the required
- the application strip pour on should be along the middle of the back of all the way from the top of head to the tail
- avoid dipping goats

99
does will ____ from the herd and will ____ their kids in an isolated part of the paddock (parturition)
separate
plant
100
newborn kids have low amounts of ____
subQ fat so v susceptible to death due to cold expose
101
paddocks for does to kid in should have
good shade and tree shelter from cold winds and protection from predators
102
kids very susceptible to predation by
- foxes, wild dogs, pigs
- in first week of life
103
when does are giving births there should be in the paddock
lots of pasture supply and easy access to water
104
the growing fetus gains 70% of its birthweight in
the last 6 weeks of gestation
so does need to be on a rising plane of nutrition from this period through to the peak of lactation
105
if the quality and quantity of pasture is poor for preggo does then supplementary feeding needs to be implemented
at least 8 weeks prior to kidding

need more environmental enrichment
116
goats compared to sheep eating
they browse more and able to digest lower quality herbage
117
when offered fresh green pasture they will select
the most highly digestible grasses in preference to clovers
118
dietary preference percentage of grass, non woody broad leaf (forbs) and browse
- grass 30%
- forbs 40%
- browse 30%
productivity is maximized when goats fed forage diets of high digestibility
119
overstocking or uncontrolled feral pops will lead to
severe land degradation
