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

The prevalence of subclinical endometritis and intrauterine infections in repeat breeder cows
The objectives of this study were to assess the prevalence of subclinical endometritis and the presence of common uterine pathogens in repeat breeder cows. A total of 121 cows with three or more consecutive artificial inseminations without conception and no clinical signs of disease were defined as repeat breeder cows and were enrolled in this trial ...

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

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 ...

STUDIES ON CLINICAL EFFICACY OF SOME THERAPEUTIC REGIMENS FOR THE MANAGEMENT OF ENDOMETRITIS IN COWS [PDF]
A total of 124 cows were treated with various therapeutic regimens by different routes. In the first group, Ciprofloxacin was administered through intrauterine route with clinical recovery of 87.88 percent and were inseminated in subsequent estrus with

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

ASSESSMENT OF NUCLEAR MATURATION AND OOCYTE VIABILITY IN NORMAL AND REPEAT BREEDER CROSSBRED COWS BY USING FLUORESCENT STAINING [PDF]
The study was carried out in 12 normal and 12 repeat breeder crossbred cows. These cows were further divided into four groups of six animals in each group.

ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.
