Genomic evaluation of productive-life indicators associated with longevity in Girolando cattle under tropical dairy conditions

Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle.

The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment. Since the pre-weaning period is crucial for development, this study aimed to e...

Genomic background of gestation length and calving-related traits in Holstein cattle.

The reproductive success of cows directly influences the profitability of dairy farms. Reproductive traits, particularly calving-related traits, generally have low heritability but sufficient additive genetic variance to enable genetic progress through genomic selection. Thus, the primary objectives of this study were...

Genome-wide association analysis reveals genetic architecture of fertility traits in Sahiwal heifers and cows

GENETIC EVALUATION OF LINEAR TYPE TRAITS AND THEIR ASSOCIATION WITH MILK PRODUCTION TRAITS IN BEETAL GOATS IN PAKISTAN

Genetic Parameters and Genome-Wide Association Analysis of Reproductive and Calving Traits in Jersey Cattle

Simple Summary Reproductive performance is important for the efficiency and sustainability of dairy cattle production. However, the genetic factors affecting reproduction may differ between young heifers and adult cows. In this study, we analyzed reproductive and calving records from Jersey cattle to investigate how ge...
