Genetic relationships between calving interval and body condition score conditional on milk yield.
Body condition score (BCS) is a useful tool in assessing the energy status of dairy cattle. Previous research has shown that it is heritable and genetically correlated to reproductive performance. Currently, interest exists in developing selection indexes for fertility that include BCS information. Before such indexes are developed, it is important to assess the genetic covariance between BCS a...
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...
متن کاملGenetic and environmental relationships between body condition score and milk production traits in Canadian Holsteins.
The objective of this research was to estimate genetic parameters of first-lactation body condition score (BCS), milk yield, fat percentage (Fat%), protein percentage (Prot%), somatic cell score (SCS), milk urea nitrogen (MUN), lactose percentage (Lact%), and fat to protein ratio (F:P) using multiple-trait random regression animal models. Changes in covariances between BCS and milk production t...
متن کاملInfluence 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 کاملHeterogeneous Within-Herd Variance. 2. Genetic Relationships Between Milk Yield and Calving Interval in Grade Holstein Cows
Genetic and phenotypic (co)variances for mature equivalent yield of 4% FCM and calving interval were simultaneously estimated by REML for grade Holstein cows in first and second parity. Data were 305d mature equivalent lactation records and calving dates for 299,441 daughters of 2489 AI sires first calving from 1970 to 1985 in California, New York, or Texas. Data were divided into three time pe...
