Perspective: Prolonged cow-calf contact—A dilemma or simply another step in the evolution of the dairy industry?

Journal of Dairy Science
: The contentious issue of cow-calf separation at birth is incongruent with many views on acceptable farming practices, and carries the risk of eroding public trust in the dairy industry if it is not addressed.

Estimation of Genetic Parameters and Genetic Trends for Growth and Reproductive Traits in Mashona Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Mashona cattle are an indigenous Sanga cattle breed from Zimbabwe, used for beef production and known for their mothering ability and adaptation to harsh tropical environments. Growth and reproductive traits are key determinants of efficiency in beef production.

Calf performance in a cow-driven cow-calf contact system: Effect of 2 methods to gradually reduce cows' access to their calf

Journal of Dairy Science
: Knowledge is lacking on separation strategies that can best prepare calves to final separation from the dam in cow-calf contact (CCC) systems. This controlled trial compared the effects of 2 different methods to gradually reduce cows' access to their ...

Minimizing cows’ stress when calves were early weaned using the two-step method with nose flaps

Animal, 2016
Early weaning may be used in beef cattle production to improve reproduction rates in range conditions. However, weaning causes a stress response in cows, which may be especially strong in early weaning management, as the bond between the cow and the calf

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.

Consequences of weaning and separation for feed intake and milking characteristics of dairy cows in a cow-calf contact system

Journal of Dairy Science
: In cow-calf contact (CCC) systems breaking the maternal bond may induce stress for the cow, thereby affecting feed intake, milk yield, milk flow rate, and milk electrical conductivity.

Evaluation of Multi‐Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Genomic prediction in beef cattle is particularly challenging in breeds with limited phenotypic and genotypic data. In this context, multi‐breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data‐scarce conditions.

What Difference Does a Visit Make? Changes in Animal Welfare Perceptions after Interested Citizens Tour a Dairy Farm. [PDF]

PLoS ONE, 2016
Citizens' concerns about farm animal welfare are often dismissed on the assumption that they are not well informed about farming practices. We conducted exploratory surveys of interested citizens (n = 50) before and after a self-guided tour of a 500-head

Safe and Stable Germline Transmission of MSTN Mutations in Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT With the global population expected to reach 10 billion by 2050, sustainable livestock production is critical. Gene editing of the myostatin (MSTN) gene represents a promising strategy to enhance muscle growth in cattle. In this study, MSTN‐mutated founder (F0) cows were used to generate F1 offspring via ovum pick‐up, in vitro fertilization ...
