The purpose of our Study was to determine if variation in milk yield at later Stages of lactation can be explained by expressions of early lactation somatic cell score (SCS) and if the prediction of future yield within lactation can be improved by including SCS among the predictors. Three data sets (n >600.000 each) we …
… eason of freshening, lactation number, and their different interactions on 305-day mature equivalent (ME) milk yield of Holstein Friesian cows in the United Arab Emirates (UAE). It also aimed to estimate sire and error variance and heritability of 305-day ME milk yield. The data was collected from AL Salamat Dairy Farm …
… in the non-administered goats. Provision of CHI showed no effect on feed intake but increased (P = 0.052) milk yield of does administered with CHI0.4 more than those with CHI0.0. However, the CHI-supplemented group showed greater milk protein (P = 0.048) and lactose (P = 0.031) contents, energy-corrected milk (P = 0.03 …
… ncentrate (APC) as supplemental protein sources for high-producing dairy cows. Dairy cows with an average milk production of 35.2 kg/day were paired and randomly assigned to one of the treatments. A double reversal design was employed With 35 days per period. The comparison between treatments was made during the last 2 …
… dried sardines were incorporated into diets for lactating dairy cows. Fourteen Holstein and 13 Australian Milk Zebu multiparous cows were used in a 70-day continuous feeding experiment. lsonitrogenous and isoenergetic diets containing either soybean meal or dried sardines (supplied 40% of dietary crude protein) were fe …
… ers of first lactation traits of Nili Ravi buffaloes under a multiple trait animal model. First lactation milk yield was l7% heritable when traits such as age of calving interval were considered. Age at first calving was 18% heritable with very low genetic correlations with other traits. Lactation length, dry period an …
