This study was designed to determine the effect of physical form and urea treatment of rice straw on rumen fermentation, microbial protein synthesis and nutrient digestibility. Four rumen-fistulated d...
The aim of this study was to determine the effect of different physical forms and urea treatment of rice straw on feed intake, rumen fermentation, and milk production. Four, multiparous Holstein cross...
Two experiments were conducted to determine an optimum Lys:calorie ratio (g of total dietary Lys/Mcal of DE) for growing barrows and gilts in cool and hot seasons in a commercial environment. In Exp. ...
Four, ruminally fistulated crossbred (Brahman×native) beef cattle with initial body weight of 420±15 kg were randomly assigned according to a 4×4 Latin square design. The dietary treatments were mulbe...
To evaluate the effects of replacing concentrate with urea molasses treated fermented wheat straw (FWS) ensiled with cattle manure (CM) on ruminal characteristics, in situ digestion kinetics and nitro...
The objective of this study was to determine the optimum ratio of methionine to methionine plus cystine for growing pigs. A nitrogen balance trial was conducted using a total of 21 barrows (Large Whit...
专著信息 书名 Molecuar Dynamics Simulations of Urea and Thermal-induced Denaturation of S-peptide Analogue 语种 英文 撰写或编译 作者 Zhiyong Zhang,Yongjin Zhu,Yunyu Shi 第一作者单位 出版社 Biophysical Chemistry, 89,145-162,200...
A total of one hundred and forty four weaned pigs with an average BW of 8.09??.05 kg were used in a 28 day study to investigate the effects of fermented soy protein on growth performance, blood urea n...
This study estimated the effects of parity (1-3) and stage of lactation (early, mid and late) on daily milk yield (DMY), somatic cell score (SCS), milk urea nitrogen (MUN), blood glucose, and immunogl...
Four male crossbred native beef cattle (average body weight of 427.7 kg) were randomly allocated to four types of cassoy-urea pellet as a source of protein in concentrate according to a 4횞4 Lat...
Four, lactating dairy cows were randomly assigned according to a 2횞2 Factorial arrangement in a 4횞4 Latin square design to study supplementation of urea level (U) at 2 and 4% and sodium ...
Influences of urea treated corncobs (UTC) ensiled with or without different additives on ruminal characteristics, in situ digestion kinetics, nutrient digestibility and nitrogen metabolism were examin...
The study was undertaken to investigate the validity of milk urea concentration as an index of the reproductive performances in crossbred Karan-Fries (Holstein Friesian횞Tharparkar) cows under f...
The study was conducted to assess the effect of milk production, parity, stage of lactation, season and individual milk components themselves on milk urea nitrogen (MUN) concentration and other milk c...
The influence of varying levels of urea and additives on nitrogen (N) retention and chemical composition of wheat straw was studied. The wheat straw was treated with 4, 6 and 8% urea and ensiled with ...
