Phenotypic variances for linear and transformed weight traits were partitioned into residual, direct genetic (D) and maternal genetic (M) components using REML techniques with American Simmental Association data from calves born 1969 to 1985. Variance components were estimated separately from subclasses defined by sex (male, female) and percent Simmental (50, greater than or equal to 75). The m...

ABSTRACT: The aim of this study was to evaluate the influence different non-genetic effects on indicator traits for maternal ability in Santa Inês ewes. Data included performance records 100 lambs (males and females) born from 59 dams, 2009 2012. analyzed were birth weight (BW), weaning (WW), average daily gain until (ADGBW), total litter at (TLWB), (TLWW). year lamb, season, dam age lambing, s...

The aim of this paper was to estimate direct and maternal genetic parameters for calving ease (CE), birth weight (BrW), weaning weight (WW), and calving interval (CI) to assess the possibility of including this information in beef cattle improvement programs. Field data, including a total of 59,813 animals (1,390 sires and 1,147 maternal grand sires) from the Asturiana de los Valles beef cattle...

in order to compare the effects of different weaning strategies on feed intake, structural growth measurement and health, blood metabolites and economic efficiency of young dairy calves, twenty four female holstein calves were used. calves after birth were randomly assigned into one of three weaning strategy as follow: 1) weaning based on feed intake, 2) weaning based on weight gain (30 kg weig...

BACKGROUND The scale of overweight and obesity in the UK places a considerable burden on the NHS. In some areas the NHS has formed partnerships with commercial companies to offer weight management services, but there has been little evaluation of these schemes.This study is an independent audit of the Weight Watchers NHS Referral scheme and evaluates the weight change of obese and overweight ad...

Two independent trials were carried out to evaluate the effect of feed form, whole wheat (WW) and oat hulls (OH) addition on gastrointestinal (GIT) weight and Campylobacter jejuni colonization in orally infected birds. In Trial 1, there were six treatments factorially arranged with two feed forms (mash vs pellets), and three levels of WW from 1-21/22-42d: 0/0, 7.5/15%, 15/30%. Broilers were all...

baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...

Our objectives were to estimate genetic parameters for carcass traits and evaluate the influence of slaughter end point on estimated breeding values (BV). Data provided by the American Simmental Association were divided into three sets: 1) 9,604 records of hot carcass weight (CW) and percentage retail cuts (PRC), 2) 6,429 records of CW, PRC, and marbling score (MS), and 3) 1,780 records of CW, ...

BACKGROUND We conducted a systematic review to examine the efficacy of the Atkins, South Beach, Weight Watchers (WW), and Zone diets, with a particular focus on sustained weight loss at ≥12 months. METHODS AND RESULTS We systematically searched MEDLINE, EMBASE, and the Cochrane Library of Clinical Trials to identify randomized controlled trials (RCTs) published in English with follow-up ≥4 we...
