Adrenergic, alpha-1B-, receptor (ADRA1B) and peroxisome proliferator-activated receptor gamma, coactivator 1 beta (PPARGC1B) genes are involved in regulation of hen ovarian development. In this study,...
动物的采食量同时受到短期和长期调控,这些调控对采食量起到平衡作用,防止个体产生绝食或暴食的情况。个体在一次采食中可能吃不饱,一顿中可能包含多次采食,在顿内或顿间都会形成一定的采食间隔。本文综述了采食间隔的分类、不同动物采食间隔的特性、通过拟合采食间隔有效估计顿间跨度的方法,以及数据结构对采食间隔分布的影响,旨在为采食性状的进一步分析和研究奠定基础,为动物的采食行为调控提供参考。
The objective of the study was to evaluate fattening performance, carcass value and meat quality in pigs of Prestice Black-Pied breed in relation to slaughter weight (SW) and gender (barrows and gilts...
Ginsenoside Rg1 is a natural compound with various efficacies and functions. It has beneficial effects on aging, diabetes, and immunity, as well as antioxidant and proliferative functions. However, it...
本研究对不同生长速度的鸭品种出雏后体重及胸、腿肌重的生长发育进行差异分析,为系统了解鸭骨骼肌的动态发育变化奠定基础。测定高邮鸭和金定鸭0~70日龄14个生长点的体重、胸大肌重和腓肠肌重,比较不同品种各个生长点体重、胸大肌重、腓肠肌重的累积生长、绝对生长、相对生长,并用Gompertz、Logistic和Bertalanffy 3种模型拟合生长曲线,根据模型的参数计算拐点重以及拐点日龄。结果:1)从...
The objective of the present study was to estimate genetic parameters and predict breeding values of sport horses in the Czech Republic using animal model variations. The data set for the evaluation w...
The aim of the study was to verify the hypothesis that the crypto-tobiano horses which do not exhibit the full tobiano white-spotting pattern nonetheless transmit the dominant To gene to the progeny...
Enteric histology of newborn goat kids fed lyophilized bovine colostrum (LBC) was studied. At 0, 7, and 14 h of life 15 male newborns received 5% of body weight of lyophilized bovine colostrum and 14 ...
The Posavina and Croatian Coldblood are Croatian autochthonous horse breeds with interwoven breeding histories for which studbooks have only recently been established. The Lipizzan breed has the oldes...

We predict the stability of breeding values (BVs) for direct effect (DE) and maternal effect (ME) for live weights at 210 days of age in the entire population of purebred Aberdeen Angus cattle in the ...
Growth and survival rates (specific growth rate – SGR; survival rate – S) of Barbus barbus L. were recorded in captivity during three years from the larval period (final body weight – W = 0.2 ± 0.03 g...
Stability of estimated breeding values for average daily gain (ADG) between 5 and 10 weeks of age was analysed for 47 242 Pannon White rabbits, reared in 7470 litters and born between 2000 and 2008. T...
Genetic parameters, breeding values and inbreeding depression for 22 linear type description of conformation and type characters and 4 body measurements were evaluated in a group of 1744 horses of thr...
An experiment was conducted to evaluate the effect of pea-based diet fed to growing and finishing pigs on performance, carcass and meat quality. Thirty pigs (Slovak White Meaty or crossbred Slovak Whi...
