Effects of Body Condition Score and Score Change on the Reproductive Performance of Dairy Cows: A Meta-Analysis

Theriogenology, 2003
A meta-analysis was conducted to evaluate the effects of body condition score (BCS) at parturition and at first AI, and of body condition change during the early lactation period on the variables pregnancy rate at first AI and number of days open in dairy cattle. Inclusion criteria for the publications were: comparison of at least two groups of animals

Adjusting weight for body condition score in Angus cows

Journal of Animal Science, 1992
Weight, height, and body condition score data supplied by the American Angus Association were used to determine the effect of body condition score on cow weight and to compute condition score adjustment factors. Single records on 11,301 cows for weight and 7,769 cows for height were collected at or near weaning, at which time a subjective condition ...

Weight necessary to change body condition scores in Angus cows

Journal of Animal Science, 2002
Weights and body condition scores (BCS) were measured and assessed on Angus females (n = 367) over 14 yr (1981 to 1994) to allow calculation of weight adjustments for different BCS. Data were collected at five time periods: prepartum, postpartum, prebreeding, postbreeding, and midgestation.

Body condition score, health, yield and fertility in dairy cows

Veterinary Record, 1997
The effects of body condition score at drying off and after calving and the rate of loss of body condition score during the dry period on the performance of 2162 cows in eight commercial Israeli Holstein herds were evaluated. The relationships between health, fertility and yield and body condition score were examined by using multiple logistic ...
