A total of 629 DurocLandraceLarge White crossbred pigs were utilized in three experiments (Exp. 1, 222 pigs weighing 25.62.0 kg BW; Exp. 2, 216 pigs weighing 56.24.3 kg...
Sixty four, 30-week-old, Lohmann Brown-Lite laying hens were randomly allocated to one of four treatments with eight replicates per treatment and two hens per replicate for a 10 week study. The contro...
The objective of this study was to determine the effect of genotype (slower-growing vs. fast-growing) and production system (access to outdoors vs. indoor) on the growth performance, carcass yield and...
Four 4-month old CharolaisDorset male sheep (initial liveweight 25.01.1 kg), fitted with rumen and abomasal fistulas and nourished by total intragastric infusions, were used to study t...
Objective of this study was to examine the effect of sodium nitroprusside (SNP), a nitric oxide (NO) donor on steroid synthesis, growth and apoptosis of buffalo granulosa cells (GCs) in vitro. Follicu...
To determine the efficiency of copper (Cu) supplementation, a feeding experiment was carried out with 240 day old broiler chicks (vencobb-100). Birds were divided into four dietary treatments: i) C - ...
The objective of the study was to evaluate the effect of passive transfer status, determined by measuring serum immunoglobulin (Ig) concentration 24 hours after parturition, on growth performance in b...
This study was conducted to compare the effects of dietary supplementation of Sodium Gluconate (SG), Mannan Oligosaccharide (MOS) and Potassium Diformate (PDF) on growth performance and small intestin...
A trial was performed to study the effects of feeding a diet containing solid-state fermentation rapeseed meal (FRSM) replaced soybean meal (SBM) on growth performance and serum biochemistry parameter...
The growth rate of the young pig is generally much less than it’s potential and may be constrained by endocrine status as well as nutrient intake. Growth factors are present in relatively high quantit...
The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of n...
An experiment was conducted to evaluate the effect of replacing barley and soybean meal in finishing diets with sesame hull (SH) on growth performance, digestibility, and carcass characteristics of Bl...
2006~2008年,在泥河湾盆地山神庙咀化石点发现大量保存完好的哺乳动物化石,已初步鉴定出如下种 类:兔科(属、种未定)、鼠兔(未定种)、直隶狼、猫科(属种未定)、硕鬣狗(未定种)、草原猛犸象、披毛犀、板齿犀 (未定种)、长鼻三趾马(未定种)、三门马、猪(未定种)、真枝角鹿(未定种)、转角羚羊(未定种)及中国羚羊等;尽 管上述种类全部属于经典泥河湾动物群成员,但其中草原猛犸象、披毛犀、野猪...
本试验旨在研究饲粮蛋白质水平对冬毛期水貂血清含氮物质、氮代谢和抗氧化能力的影响。选择90日龄健康雄性水貂60只,随机分成6组(每组10个重复,每个重复1只水貂),分别饲喂蛋白质水平为28%(Ⅰ组)、30%(Ⅱ组)、32%(Ⅲ组)、34%(Ⅳ组)、36%(Ⅴ组)、38%(Ⅵ组)的试验饲粮。预试期7 d,正式期90 d,饲养试验结束后进行屠宰,制备血清并测定相关生化指标。结果表明,Ⅲ组水貂的血清总蛋白...
本文基于实验室筛选得到的13 对内含子标记,在鲸偶蹄目的15 个物种中进行有效扩增,并重建了这15个物种的系统发育关系。结果表明,抹香鲸总科(Physeteroidea) 位于齿鲸亚目(Odontoceti)的基部,从而支持了传统的齿鲸亚目的单系性。在海豚总科(Delphinoidea)内部,贝斯分析结果支持了鼠海豚科(Phocoenidae)和一角鲸科(Monodontidae)的姐妹群关系,而...
