Influence of Body Condition Score on Yield and Composition of Milk in Crossbred Dairy Cows
The study was carried out for a period of 150 days on 120 Holstein Friesian crossbred dairy cows between mid to late lactation to quantify the influence of body condition score (BCS) on yield and composition of milk. Total 12 dairy farms having same housing systems and holding at least 20 crossbred dairy cows per farm between mid to late lactation were selected for this study purposes. BCS of i...
متن کاملPrenatal maternal effects on body condition score, female fertility, and milk yield of dairy cows.
In this study, maternal effects were described as age of dam at first and second calving, first-lactation body condition score (BCS) of the dam during gestation, and milk yield of the dam. The impact of these effects on first-lactation daughter BCS, fertility, and test-day milk yield was assessed. The effect of milk yield of dam on daughter 305-d yield in the latter's first 3 lactations was als...
متن کاملDifferences between primiparous and multiparous dairy cows in the inter-relationships between metabolic traits, milk yield and body condition score in the periparturient period.
During the early postpartum period dairy cows mobilize fat and muscle to support lactation. This is associated with alterations in blood metabolite and hormone profiles which in turn influence milk yield and fertility. This study developed models to determine how metabolic traits, milk yield and body condition score were inter-related at different times in the periparturient period and to compa...

متن کاملCausal Relationships Between Milk Yield, Body Condition Score and Fertility in Italian Holstein Friesian Dairy Cattle
The aim of the study was to explore genetic relationship among milk yield, body condition score (BCS) and pregnancy status (PR) in Italian Holstein cows using a recursive effects model. Two recursive models and a multiple-trait model were compared in four different subsets of data. The antagonistic effect of milk yield on BCS and PR was confirmed, as well as the positive relationship between BC...
