Genetic Analysis of Surti Buffalo for Production and Fertility Performance Traits

Background: Simple univariate restricted maximum likelihood models were used to estimate the variance components for production performance traits of surti buffaloes reared under sub humid region. Records of 649 parity of 203 animals of 34 sires were taken to estimates the production and reproduction traits over a peri...

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

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. In this context, the main objectives of this study were t...

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...

Estimates of genetic parameters for growth traits to develop a genetic evaluation system in Mexican Hampshire sheep

The estimation of genetic parameters is an essential component when developing genetic evaluation systems for livestock. A genetic evaluation was conducted for Mexican Hampshire sheep by using a pedigree of 16,478 animals. We estimated genetic parameters for growth traits and investigated the current genetic...

Estimation of Heritability and Breeding Values in the Growth Traits of Local and F1 Crossbreed Buffaloes in Bangladesh

Estimation of heritability and breeding values is essential for improving economically important traits and identifying superior individuals in buffalo populations. This study evaluated growth traits in 33 Local/Indigenous and 35 F1 crossbreed (Local × Mediterranean Italian) buffalo progenies using a single-trait anima...

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...
