The Leptin gene is the that produces leptin hormone, which released from adipose tissue and can increase productivity of animals. This study aimed to identify polymorphic nucleotides, changes in amino acid components, species goats based on GenBank DNA sequence data. A total five goat sequences were extracted NCBI was aligned with Bioedit locate SNPs changes. tree cultivars grown using Clustal ...

The article provides data on the weight growth of bulls different types productivity. and development Black-and-white, Simmental Aberdeen-Angus were studied during period their rearing feeding. change in live was established, dynamics rate calculated depending breed type research results showed that had highest fattening - 485.2 kg, which significantly higher than Black-and-White breeds by 68.7...

For the first time, in conditions of Magadan Region, studies were carried out on use a feed additive (FA) prepared from dwarf pine ( mountainpine ) combination with lichens feeding young cattle Holstein breed and crossbred animals Golstein Hereford breeds. Over period experiment, absolute increase experimental bulls exceeded indicators control groups: by 2.15 kg (0.58%), hybrids 6.35 (1.51%). T...

INTRODUCTION Modern beef cattle used for our beef production are not exactly a property left by our ancestors, but composed products from native and imported cattle. Most native cattle were graded up by British and continental breeds for a few generations about 90 years ago. It should be pointed out, however, that they are the sole domestic farm animals in our country contributing to practical ...

Gastrointestinal nematodes are a major cause of disease in grazing livestock; however, individual animals differ in their response to infection. To identify genes whose expression correlates with resistance status, transcriptional profiling of resistant and susceptible sheep was undertaken. Transcription profiles were taken at three time points during the growth of lambs. The number of genes di...

Beef cattle breeds consist of three major genetic subdivisions. The taurine group is adapted to temperate environments, and the zebu and Sanga groups are both adapted to tropical environments. With the advent of genotyping and sequencing technologies in agriculture, genome-wide exploration of the genetic basis for the differences in tropical adaptation has only just become possible. In this stu...

The results of the assessment amino acid profile longest muscle back Kemerovo breed pigs and its two-breed three-breed crosses with commercial breeds are presented. largest amount acids is found in meat purebred animals comparison two- threebreed animals. In terms content such as phenylalanine, aspartic acid, serine, glutamic significantly exceeded hybrids. It was shown that studied groups for ...

Alterations in candidate genes by way of substitutions, insertions, or deletions at restriction enzyme cleavage sites may produce changes in the resulting length of DNA fragments called restriction fragment length polymorphisms, which may serve as genetic markers if they are linked to quantitative trait loci. Recently, single nucleotide polymorphisms (SNPs) have gained high popularity as marker...

We performed a genome-wide association study for Warner-Bratzler shear force (WBSF), a measure of meat tenderness, by genotyping 3360 animals from five breeds with 54 790 BovineSNP50 and 96 putative single-nucleotide polymorphisms (SNPs) within μ-calpain [HUGO nomenclature calpain 1, (mu/I) large subunit; CAPN1] and calpastatin (CAST). Within- and across-breed analyses estimated SNP allele subs...

the objective of the present study was to scan the whole genome in sheep for identifying the loci associated with wool diameter. blood samples were collected from 94 animals, consisting 47 samples per each lori-bakhtiary and zel breeds. genotyping of samples were performed using ovine 50k snp chip arrays. quality control filters were applied for the initial genotyping data and 48,056 snps belon...
