Purpose The objective of this review was to discuss the effects of selection for milk
production in beef production systems on productivity and profitability. Sources The sources …

Mammalian females pay high energetic costs for reproduction, the greatest of which is
imposed by lactation. The synthesis of milk requires, in part, the mobilization of bodily …

This study assessed milk yield and composition of Angus and Angus-cross beef cows raised
in southern Brazil. A total of 128 records were collected in 2 consecutive calving seasons …

Genetic evaluations provide information to aid in breeding decisions that increase long-term
performance of animals and herds. However, to date no study has been undertaken to …

Pregnancy rate, calving interval, birth weight, weaning weight, and quarterly BCS were
collected for 5 consecutive years on 454 fall-calving multiparous British crossbred cattle (3 to …

The beef cattle industry tends to focus on selecting production traits with the purpose of
maximizing cow-calf performance. One such trait is milking ability, which is considered the …

Abstract Brangus cows (n= 29) were used in three experiments to evaluate the effects of
parity (multiparous vs. primiparous) and potential genetic merit for milk production (high vs …

The objectives of this study were to quantitatively summarize factors associated with cow
milk yield (MY) and calf growth response in pasture-based beef cow-calf suckler systems …

Gastrointestinal helminths are a problem in the production of ruminants, parasitized animals
show delayed growth. The present study evaluated the association between fecal egg count …

Agriculture is an important source of greenhouse gases (GHG), especially from crop
production practices and enteric fermentation by ruminant livestock. Improved production …
