The growth and maturity of cattle body size affect not only feed efficiency, but also productivity and longevity. Dissecting the genetic architecture of body size is critical for cattle breeding to improve both efficiency and productivity. The volume and weight of body size are indicated by several measurements. Among them, Heart Girth (HG) and Hip Height (HH) are the most important traits. The...

Adult Mice (BWt. 30 gms and 40gms) were treated at a 5mg\kgBWt. and 10 mg/kg BWt. of Ethidium Bromide for 10 days in drinking water. Control animals were given equal dose of deionised water. Quantitative and qualitative changes were studied in Spleen. The following features were evaluated: the overall cellularity of the spleen was noticed. The changes were characterised by, injury to spleen tis...

Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex and batch), covariates (birth weight, cold carcass weight, and age), random effects (additive, litter ...

Context Spirulina platensis (SP) has been found to be an important dietary supplement for boosting animal growth performance, having a high protein content (60–70% on dry-matter basis) with minimal toxicity. Aims The effect of supplementation the and performance two Omani goat breeds (Jabbali Sahrawi) was investigated. Methods Thirty-six 11-month-old bucks from were studied 70 days at Livestock...

the present study investigated the calpain gene diversity in iranian one-hump camels (120 camels) using pcr-rflp method. three genotypes aa, ag and gg were observed with the frequencies of 0.02, 0.19 and 0.78, respectively. the frequencies of a and g alleles were 0.12 and 0.88, respectively. the chi-squared test didn’t show significant deviations from hardy-weinberg equilibrium (p<0.05). associ...

The aim of this study was to evaluate genomic information inclusion in genetic parameter estimation standardized body weight at birth and 240, 365, 450 days age, visual scores for structure, precocity, muscularity, measured as yearlings Nelore cattle. We compared parameters, (co)variance components (estimated from Bayesian inference Gibbs sampling), breeding value accuracies, trends, principal ...

Background: The profitability in swine production is mostly associated to the superior growth performance. information pertaining genetic and non-genetic factors influencing traits significant enable animal breeders adopt better selection managemental methods. Methods: Data from 50% LWY-Desi group 75% that were maintained at All India Coordinated Research Project (AICRP) on Pigs, Sri Venkateswa...

The CGC population is a stabilized composite of 1/2 Red Angus, 1/4 Charolais, and 1/4 Tarentaise germplasm. The objectives of this research were to estimate genetic parameters for weight traits of CGC and to evaluate genetic responses resulting from selection based on the following index: I = 365-d weight 3.2(birth weight). Phenotypes evaluated were birth weight (n = 5,083), 200-d weight (n = 4...

The aim of this study was to analyze the effect of sex, season and year of birth on growth rate of biometric measurements and body weight gain of Thoroughbred foals during first six months of life. 103 Thoroughbred foals (53 colts and 50 fillies) from Golejewko Stud born between 2006 and 2008, were used in this study. Thoroughbred foals born in winter months were characterized by significantly ...
