-% of revenue in dairy farms is from the milk sales -% of the variation in income from milk sales is due to reproductive management.
Most methods of income on a diary farm rely on what?
The farmer being able to administer drugs successfully
The farmer successfully monitoring BCS
A successful pregnancy
The lactation of the cow
T/F: the key between high and low-income dairy farmers is a higher rate of pregnancy
Marginal cost of production = what is the of In this case it is just the feed cost.
What does having a higher rate of production do for a farmer in terms of profit-making?
Dilute the fixed costs
Dilute the variable costs
Decrease the marginal cost of production
Erase the variable costs
T/F: in order to fix a problem with the biology of the cow (it is ill) you should look for better opportunities to get to a new profit level
When is the cow making profit for the farmer?
in the dry period
First 170 days of lactation
First 50 days of lactation
From 150 - 250 days after calving
T/F: you will have greater profit if you shorten the calving interval and return cows to calving quicker than before
What is true about the BCS in dairy cows?
It should remain roughly the same throughout the entire year
Having large changes in BCS will prolong the calving interval
Very thin cows will struggle to get into heat, and very heavy cows have a normal heat cycle
Fat cows have higher chance of metritis and fatty liver
Thin cows are a result of poor feeding, fat cows are not
First ovulation is greatly determined by BCS and important as the sooner the first ovulation happens the more likely they are to be in calf by 100 days in milk.
Looking for a lactation curve that peaks at - weeks and maintains that for another - weeks. (then start to drop at % per week)
The voluntary waiting period is the time after calving when not wanting the cow to be in calf/ mated How long is it usually?
40-50 days
70-80 days
20-30 days
14-28 days
T/F: culling is an expense
The following are all measures for cow comfort but which is the most useful
Lying index (number lying cows Vs total in pen)
Free-stall use index (number of cows lying minus those not eating/drinking )
Cow comfort index (lying Vs lying and standing)
