IMPACTS OF A LEPTIN SNP ON GROWTH PERFORMANCE AND CARCASS CHARACTERISTICS IN FINISHING STEERS STUDIED OVER TIME

May 30, 2017

Impact of leptin SNP on growth studied over time 2017 ABSTRACT: A total of 2,948 steers (mean initial BW = 568.9 ± 49.4 kg) were used to evaluate the effect of the LEP R25C SNP genotype on feed intake, growth performance, and carcass characteristics over time.  Steers were grouped into 5 blocks, each consisting of 10 […]

PERFORMANCE AND CARCASS CHARACTERISTICS WHEN SORTING FEEDLOT CATTLE ON THE BASIS OF PHENOTYPE, AND LEPTIN GENOTYPE ALONG WITH DIFFERENTIAL USE OF b-ADRENERGIC AGONISTS

October 1, 2015

Leptin sorting trial 2014 ABSTRACT: Crossbred steers were used in a randomized complete block design to evaluate a feedlot cattle sorting system.  The sorting system combined information on live body weight, ultrasound fat thickness, coat color, and leptin R25C genotype.  Using described sorting criteria, a total of four groups (Groups 1-4) of cattle were created […]

IMPACT OF LEPTIN SNP AND RACTOPAMINE ON GROWTH AND CARCASS CHARACTERISTICS IN FINISHING STEERS

February 12, 2015

Impact of Leptin SNP and RH on growth and carcass 2014 ABSTRACT: A total of 2,958 steers (mean initial BW = 549.6 ± 3.88 kg) were used to test for the interactive effects, of leptin R25C genotypes (CC, CT, or TT) and feeding of ractopamine hydrochloride (RH) on growth performance and carcass traits. Before application of […]

IMPACT OF A LEPTIN SNP AND ZILPATEROL ON GROWTH AND CARCASS CHARACTERISTICS IN FINISHING STEERS

October 1, 2013

Impact of LEP SNP and ZH on growth and carcass_2013 ABSTRACT: A total of 4,178 steers (mean initial BW = 403.9 ± 16.04 kg) were used to test the interactive effects, if any, of leptin R25C genotypes (CC, CT, or TT) and zilpaterol hydrochloride (ZH) feeding duration on growth performance and carcass traits. Steers were blocked […]

THE EFFECT OF A LEPTIN SNP ON QUALITY GRADE, YIELD GRADE, AND CARCASS WEIGHT OF BEEF CATTLE

September 5, 2013

Effect of leptin SNP on QG, YG, HCW_JAS_Kononoff et al ABSTRACT: Feedlot producers could optimize the value of cattle in a given market grid if they were able to improve the uniformity of the body composition between cattle among loads. Allelic variation due to a single nucleotide transition (cytosine [C] to thymine [T] transition that results […]

ASSOCIATION OF LEPTIN GENOTYPES WITH BEEF CATTLE CHARACTERISTICS

September 5, 2013

Association of leptin SNP with beef cattle characteristics_Woronuk et al ABSTRACT: A single nucleotide polymorphism (C/T) in bovine leptin, resulting in an arginine to cysteine amino acid substitution (p.Arg25Cys), has previously been shown to have an impact on carcass characteristics.  Given the significant energetic relationship between fat and animal efficiency, further evaluation of this SNP […]
