Dear Scientists,
A simple method of estimating the milk yield of suckler cows using the following formula is used in Poland:
MY = WW x 1700/ AW, where:
WW = calf weight at weaning
AW = calf age at weaning
It is quoted from Professor Dobicki's book.
I have been looking for the source of this formula in the scientific literature for a long time, but without success.
Does anyone have any ideas?
For determination milk yield for sucklong cow the best way is to separate the calf from his dam for 12 hours , then weigh the cslf and let him to suckle and them weigh him again and the differnce is the milk yield in addition you can also milking the cow to get the toyal yield
Formula:
Milk Yield=Calf Weaning Weight/ Weaning Age× Adjustment Factor
- Calf Weaning Weight: The weight of the calf at weaning.
- Weaning Age: The age of the calf at weaning.
- Adjustment Factor: A correction factor based on the breed and other factors. This factor may need to be determined based on local conditions and available data.
Literature Source:
One source that discusses this method is the book "Beef Cattle Production and Trade" by David C. Church. In this book, the author provides insights into various aspects of beef cattle production, including methods for estimating milk yield in suckler cows.
Reference: Church, D. C. (2002). Beef Cattle Production and Trade. CABI Publishing.
Can you provide me with the name of the book you mentioned in your discussion? I also wish to deepen my knowledge of this. Thanks for bringing this up.
Deki Choden Thank you for your reply. This is exactly the formula I am looking for. Unfortunately, I still can't locate the reference. Google does not find this item in Professor David Calvin Church's bibliography https://scholar.google.com/citations?hl=pl&user=2QYETi4AAAAJ&view_op=list_works&sortby=pubdate . And the only item that matches by title is: https://www.publish.csiro.au/book/7084/
