how many bucks per doe
1 buck: 15-19does
jumanji
full blood boer
born fall 2016
from oak hollow livestock
first breeding season
buckling
buck under 1 year old
testes
general site of production and maturation of spern
epididymis
site in the testes of sperm maturation
vas deferens
transport sperm form epididymis to urethra
a
a
urethra
a
enis
p
sigmoid flexure
a
seminal vesicles
adds seminal fluid
conformation
strong Roman nose straight line long body good muscling symmetrical large testicles teat structure- paternally inherited pigmentation- bare skin under tail
choosing a buck
good general conformation strong pastern- we have weak pastern in the herd strong shoulder negative for CL temperament 100% full-blooded boer proven- has gotten a doe pregnant
breeding soundness exam
consist of testicles assessment and semen quality assessment
analyze tone and size
check for abnormalities
performed by vet at the beginning of breeding session
sperm evaluation
evaluate morphology and motility of sperm
semen collection
artificial vagina
electro-ejaculator
inserted rectally
making a morphology slide
- pipet a drop of semen and a drop of stain onto slide
- place the short end of a second slide against the first slide above the two spot
look at slide
motility assessment
sperm should be swimming normally
30% or higher is acceptable
pick at spot and observe 10 sperm
repeat 10 times
morphology assessment
normal morphology
droplet shaped head
straight tail
70 % or more normal is acceptable
breeding season
increase grain 2-3 weeks prior to breeding
can lose up to 10% body weight
introduce to does after ~ 10 days of teasing
remove after 42 days
buck behaviors
flehmen response
vocalization
urinates on beard and legs
breeding harness
indicates the date of breeding
color of chalk changed after first estrous cycle
can indicate if a doe is bred
different texture of chalk based on temperature
cold- 65 and below - softest
mild- 65-85
hot- 85 and above -hardest
maintenance
house away from does when not breeding
housed alone or with wether
feed demand is generally low
monthly health check
caseous lymphadenitis
CL
chronic bacterial infection that affects lymph node
transmit through wounds and mucous membrane
symptoms: absess
