The present study aimed to investigate the causal relationships between clinical mastitis and some reproductive traits, including success at first insemination (SFI), the number of inseminations to pregnancy (INS), the interval from calving...
The pigments in eggshell with different colour and the pigment regulatory gene expression in corresponding chicken's shell gland [0.03%]
不同颜色蛋壳中的色素及相应输卵管中色素调控基因的表达
Huanhuan Wang,Ying Ge,Lei Zhang et al.
Huanhuan Wang et al.
Eggshell colour is the unique appearance and economically valuable trait of eggs, whereas the colour is often short of uniformity, especially in the blue-shelled breeds, hence, their pigment differences and molecular mechanism need clarity....
Ruminal tissue uptake of amino acids in Holstein cows when supply of nutrients within the rumen differs [0.03%]
瘤胃营养供应不同的情况下荷斯坦奶牛的瘤胃组织氨基酸摄取情况
V C Souza,M Aguilar,A C Storm et al.
V C Souza et al.
Characterisation of amino acid (AA) use by the ruminal vein-drained viscera (RDV) has not been assessed in vivo in dairy cattle, and thus, the extent of ruminal AA use from arterial and postabsorptive blood supplies is unclear. Understandin...
Review: Diving into the cow hologenome to reduce methane emissions and increase sustainability [0.03%]
评述：进入牛体复合基因组以减少甲烷排放和提高可持续性
Oscar Gonzalez-Recio,Natalia Scrobota,Javier López-Paredes et al.
Oscar Gonzalez-Recio et al.
Interest on methane emissions from livestock has increased in later years as it is an anthropogenic greenhouse gas with an important warming potential. The rumen microbiota has a large influence on the production of enteric methane. Animals...
Supplementing pre- and probiotic ingredients to feedlot steers: effects on health, growth performance, and physiological responses [0.03%]
日粮中添加益生菌和益生元对肉牛健康、生长性能及生理指标的影响
S J Mackey,R F Cooke,E A Colombo et al.
S J Mackey et al.
Feedlot diets are often enriched with additives to mitigate health disorders and promote cattle performance, including the feed-grade antimicrobials monensin and tylosin. However, alternative feeding strategies are warranted given the incre...

Due to progressing anthelmintic resistance of gastrointestinal nematodes (GIN), supportive measures are needed to control these parasites. In sheep, it has been shown that selection towards an increased nematode resistance is feasible and t...
"If you were a cow, what would you want?" Findings from participatory workshops with dairy farmers [0.03%]
如果你是一头奶牛，你会想要什么？与乳品农场主参与式研讨会的发现

When looking to improve animal welfare, it is essential to understand the viewpoints of stakeholders in the industry. Previous research has engaged stakeholders such as farmers, veterinarians, and the public to better understand future dair...
An in vitro model for caecal proteolytic fermentation potential of ingredients in broilers [0.03%]
体外盲肠蛋白水解发酵模型评估肉鸡日粮原料的发酵潜力
M L Elling-Staats,A K Kies,J W Cone et al.
M L Elling-Staats et al.
Fermentation of protein in the caeca of chickens may lead to the production of potentially detrimental metabolites, which can reduce gut health. A poor precaecal digestion is expected to increase protein fermentation (PF), as more proteins ...
Review: A systematic review of the effects of functional amino acids on small intestine barrier function and immunity in piglets [0.03%]
综述：功能性氨基酸对仔猪小肠屏障功能和免疫作用的系统评价
D Luise,T Chalvon-Demersay,F Correa et al.
D Luise et al.
The need to reduce the use of antibiotics and zinc oxide at the pharmacological level, while preserving the performance of postweaning piglets, involves finding adequate nutritional strategies which, coupled with other preventive strategies...
Strategies for choosing core animals in the algorithm for proven and young and their impact on the accuracy of single-step genomic predictions in cattle [0.03%]
公牛选择算法中核心群个体的选择策略及其对奶牛单步基因组预测准确性的影响
A Cesarani,M Bermann,C Dimauro et al.
A Cesarani et al.
Nowadays, in some populations, the number of genotyped animals is too large to obtain the inverse of the genomic relationship matrix. The algorithm for proven and young animals (APY) can be used to overcome this problem. In the present work...
