The Fat content of milk is of economic importance because milk is sold on the basis of fat. Milk fatty acids originate either from microbial activity in the rumen,and transported to the secretory cell through the blood and lymph, or from synthesis in the secretory cells. The main milk ...
The relative economic importance of the genetic changes in milk yield and milk fat percentage attributed to individual sires was investigated for artificially inseminated (AI) proven sires of the five major dairy breeds in the United States, summarized with daughter-herdmate comparisons in 1965. Twent...
Inthe total test period, the milkfat percentage of cows in test group was gradually increased and that in CKgroup changed as wave. 在整个试验期内,试验组奶牛的乳脂率逐渐升高,而对照组呈波浪形变化。 www.cnak.net 2. Factors of Milk Fat Depression and Measures Improving MilkFat Percentage 影响奶...

Multiple component pricing based on percentages of fat and solids-not-fat (SNF) in milk is employed by dairy cooperatives to fix the price of milk collected from dairy farmers in Kerala (India). A retrospective study was conducted to determine herd milk fat percentage and solids-not-fat (SNF...
Genetic parameters for first lactation milk production based on test day (TD) records of 56319 Iranian Holstein cows from 655 herds that first calved between 1991 and 2001 were estimated with restricted maximum likelihood method under an Animal model. Traits analyzed were milk yield and milk fat ...

From the work reported here the following deductions are probably justified:1.The substitution of cottonseed meal for old-process linseed oil meal and bran in the ration of milk cows produces no marked change in the percentage of fat in milk.2.The replacing of cracked corn with cottonseed meal...
The main objectives were to analyze milking-to-milking variability in milk yield, fat and protein percentages, and somatic cell count (SCC). Additional objectives were to investigate the factors that affect variation in milk fat percentage and to study the seasonal variations in milk, fat, and ...
