Causal 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 کاملBody condition score and live-weight effects on milk production in Irish Holstein-Friesian dairy cows.
The objective of the present study was to quantify the relationships among body condition score (BCS; scale 1 to 5), live weight (WT) and milk production in Irish Holstein-Friesian spring calving dairy cows. Data were from 66 commercial dairy herds during the years 1999 and 2000. The data consisted of up to 9886 lactations with records for BCS or WT at least once pre-calving, or at calving, nad...
متن کاملAssociation between body condition score and live weight in pasture-based Holstein-Friesian dairy cows.
The objective was to quantify the strength of the relationship between body condition score (BCS) and live weight (LW) in pasture-based Holstein-Friesian dairy cattle, and to determine the kg LW per unit BCS. A total of 26021 test-day records with information on both BCS (1-10 scale, where 1 is emaciated and 10 is obese) and LW across 1110 lactations from one research farm were used in the anal...
متن کاملFactors Affecting Body Condition Score and Its Relationship with Productiveand Reproductive Performances of Holstein Cows
The objective of the present study was to determine factors affecting body condition score (BCS) and its association with productive and reproductive performances in Holstein cows. Mixed model analysis was performed on monthly records of BCS from April 2006 to July 2012 comprising 34666 records from 3134 dairy cows in a large commercial dairy herd under arid climatic conditions of Isfahan in Ir...
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...
