what is the main fibre of importance economically of camelids
wool
scientific name of sheep
ovine
scientific name of goats
caprine
scientific name of llama/alpaca
camelid
scientific name of deer
cervine
where are common injection sites in camelids
- blood sampling and IV meds = jugular vein (can also use cephalic and saphenous for blood samples
- SQ in skin fold at axilla or cranial to shoulder
- IM in quadriceps, semitendinosis/semimembranosus or triceps
when do lambs go to slaughter
half their adult weight (around 40 kg)
how do you make a pregnancy diagnosis
- lack of heat
- ultrasound
- abdominal palpation
- oesterone sulphate (after 50 days) useful to test on milk
- camelids will spit off
list methods of assisted breeding
- ram/boar effect (introducing ram/boar to flock or teasing with infertile male/pheremone rag)
- sponges (progesterone impregnated sponge)
- melatonin inplants (advance breeding season so can be bred out of season)
- AI
- embryo transfer
- semen collection (for AI or assess fertility)
what is fecundity
numbers of young produced per female mated
what is fertility
number of ewes lambed per ewe mated (or goat kidded)
describe the important considerations and actions for each stage of pregnancy
early preg (first 6 weeks): keep stress to a minimum due to implantation
mid pregnancy (day 40-100): maintain bodyweight, no sudden changes as the placenta develops. if too fat can loose bcs
scan for accurate foetal membranes at day 50-100: allows twin/triplet ewes to be fed up. no extra feed necessary for single ewes, barren ewes can be sold.
late pregnancy (last 6 weeks): nutrition crucial to cope with 80% of fetal growth, development of mammary tissue and reduction of voluntary food intake as rumen capacity is reduced
what age do camelids reach puberty
males: as early as 6 months of age. used for breeding from 3 years old
females: as early as 10 months of age. breeding startwhen reached at least 60% adult body weight
what small ruminant species are induced ovulators
camelids. they dont have a true oestrus cycle
female is always potentially receptive. flexible to suit weather conditions
how many offspring do camelids give birth to per pregnancy
1
gestation: 11 months
crias usually born before 4 pm
what is the best time for camelids to conceive
20-30 days post partum
what is spitting off behaviour
female camelids rejecting males advances because they have already conceived. behaviour occurs at weekly intervals after mating and PD confirmed by US
when do deer rut and how does the behaviour of a stag change during rut
autumn
- get aggressive
- do not eat and will loose BCS

list routine goat procedures
- disbudding
- hoof trimming

- ear tagging (both ears, law rewuirement)
- oral drenching
- vaccines
