Abstract

The aim of this study was to determine the diversity of the sex-determining region Y (SRY) gene in Madura cattle bulls that had specifically selected for the production of frozen semen. DNA was isolated from the whole blood derived from 5 Madura cattle bulls and the SRY gene amplification carried out using polymerase chain reaction (PCR) with SRY-4 as a primer followed by DNA sequencing. Results revealed the proximity of the Madura cattle SRY genes to the Bos indicus SRY genes, furthermore this study also proved the existence of variation in Madura cattle SRY gene caused by mutation and deletion of nucleotides. It was concluded that the variations in Madura cattle SRY genes still persist even in the specifically selected populations with similar phenotype.

Abstract

The objective of this study was to evaluate the effect of genetic and environmental factor on locals Madura cattle semen production and quality. A total of 2275 semen collections records from 11 bulls from 2012 to 2014 were analyzed to evaluate the genetic potency of semen productions. Genetic evaluation consists of repeatability estimation of semen volume, sperm concentration and sperm individual motility. Data were analyzed by HGLM (REML) with environmental factors of age, seasons, interval of semen collections, and frequency of ejaculations as fixed effect and bulls as random effect using GENSTAT 16th edition. Result showed that age and ejaculation frequency affect to all variables; interval of semen collections affected to both semen volume and sperm concentrations; while seasons only affected to sperm concentrations. Repeatability estimation of semen volume, sperm concentration and sperm individual motility were 0.376, 0.445 and 0.567 respectively. It was concluded that the quality of Madura bulls ejaculate less affected by environmental factors.

Abstract

Ongole-grade cattle are a major locally adapted beef resource in Indonesia, yet breeding-source village populations often lack quantitative baseline phenotypes to support objective selection and on-farm conservation. This study characterised age-standardised morphometric traits of Ongole-Grade cattle from the breeding-source population in Napis Village (Bojonegoro, East Java). A cross-sectional survey was conducted on 356 clinically healthy cattle (143 males and 213 females) aged 24–48 months. Twelve linear measurements were recorded (withers height, body length, chest girth, chest depth, rump height, rump width, cervical/thoracic/lumbar vertebral lengths, scapula length, head length and head width) and standardised to 24 months using allometric size correction prior to analysis. Sex effects were tested using one-way ANOVA and Tukey comparisons, and principal component analysis (PCA) was performed separately by sex on z-standardised traits. All traits differed between sexes (p ≤ 0.002). Males were larger for most frame and head/axial traits (e.g., withers height, body length, chest depth, rump height, cervical and lumbar vertebral lengths, scapula length, head length and head width; p < 0.001), whereas females were larger for rump width, chest girth and thoracic vertebral length (p ≤ 0.002). PCA revealed a consistent conformation structure in both sexes, with PC1 representing a general size axis (47.3% variance in males; 42.7% in females) and PC2 capturing proportionality (shape), increasing cumulative explained variance to 70.8% in males and 64.5% in females. These results provide population-specific morphometric references and multivariate descriptors that can strengthen selection criteria and recording schemes for Ongole-Grade cattle in breeding-source village systems.
