Genetic Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 390-402, May 2026.
ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...

Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 411-421, May 2026.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 457-464, May 2026.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...

Impacts of Highland cattle browsing on encroaching Alnus viridis shrubs

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction In several European mountain chains, the expansion of the tall shrub Alnus viridis into mountain pastures has altered vegetation structure and composition, reduced plant species diversity, and diminished forage quality. Recent woody encroachment research has explored the use of robust livestock breeds, such as Highland cattle (Bos

Management of dairy heifers: Can operant conditioning be an effective and feasible tool to decrease stress and ease animals' close contact and handling?

Journal of Dairy Science
: Besides health monitoring, a regular check of dairy heifers' growth rate is desirable, but it is rarely done because procedures that require restraint and handling can be associated with substantial stress for both animals and farmers.

Producing Beef for Alaska's Railbelt [PDF]

, 1962
The object of this report is to try and determine what it will cost to produce beef in the Kenai Peninsula and other parts of the Railbelt. Because little beef is being produced in this area, it has been necessary to project beef enterprises, rather than
