Quality Milk Flashcards
what is the milk quality benchmark for somatic cell count?
<750,000/ml
what is the gold standard bedding?
sand
when is optimum take-off for automatic take-offs for milking?
1.3-2 lb/minute
why should gloves be worn during the milking procedure?
primary source of Staph aureus is human skin, other pathogens
reduces chapping of operator’s hands
what provides the strongest signal for letdown?
forestrip
how long is contact time for the dipper?
30 seconds
how long should it be from forestripping to attachment?
60-90 seconds
what is key to low cell counts?
removal of teat-end moisture/debris
what is bimodal milking?
initial surge of milk followed by decreasing milk flow before full let down of milk
what are effective treatments for mastitis?
intra-mammary antibiotic tube
no treat
dry-off/eliminate affected quarter
cull
what are bulk tanks sampled for?
production
somatic cell counts
components: protein/fat
drug residues
bacterial plate counts
how much milk should be stripped in strip yields?
40-100 ml/quarter
250 ml/cow
what is milk protein?
3.0-3.5%
what is milk protein and fat supposed to be?
protein 3.0-3.5%
fat 3.5-4.0%
what are goals in the holding area?
minimize wasted time
ventilation
heat abatement
movement to and from
what portion of the machine is in direct contact with the teat?
inflations/liners
what is typical milking procedure?
strip
dip
wipe
attach
what does forestripping result in?
earlier mastitis detection
faster milking
more milk production
decreases new infections by 12%
how much coverage needs to be achieves with the dipper?
75%
what does bimodal milking increase risk of?
teat end damage
what does overmilking result in?
decreased efficiency
more teat end lesions
discomfort seen as stepping and kicking
what is an internal teat sealant?
bismuth subnitrate in an oil base
no milk or pre-slaughter withdrawal
what should you pay attention to during strip yields?
cow attitude toward teats being handled
