A key aspect of husbandry is reproduction management, and current methods often rely on the use of hormonal treatments. In the ewe, which is a seasonal breeder, a combination of progestogen and equine Chorionic Gonadotropin is the benchmark...
Inclusion of rapeseed cake or oil in the diet of beef cattle reduces enteric methane emissions without affecting animal performance [0.03%]
菜籽饼和菜籽油在肉牛日粮中的添加可降低甲烷排放而不影响生产性能

N T Folliard et al.
The global methane (CH4) pledge aims to reduce anthropogenic CH4 emissions by 30% by 2030. Oilseed rape (Brassica napus L), a break crop with 40 million ha cultivated globally in 2022, produces fatty acid-rich by-products that could potenti...
Productive and reproductive parameters, rumen environment and methane emission by beef cows grazing native pastures with or without inclusion of a tannin-rich legume [0.03%]
在本地牧草中添加富含单宁的豆科牧草对肉牛生产繁殖性能、瘤胃环境和甲烷排放的影响
G Fernandez-Turren,O M Lema,G Banchero et al.
G Fernandez-Turren et al.
Beef production in pasture-based systems is often associated with relatively high methane emissions. Improving forage quality by including Lotus species may contribute to methane mitigation in rangeland systems. We aimed to evaluate the pro...
White and brown layer pullets' choice of light intensity in relation to their behaviour, age and the time of day [0.03%]
光照强度对白色和褐色分层育成鸡行为、日龄和时间的影响下的选择性
J A J van der Eijk,T G C M van Niekerk,T Izquierdo Garcia-Faria et al.
J A J van der Eijk et al.
For chickens, one of the most important senses is vision and light can influence their behaviour, welfare and productivity. For laying hens, lighting needs will differ depending on the stage of development of the bird, i.e. rearing vs produ...
Effects of α-ketoglutarate and its calcium salt on growth performance, health, rumen fermentation and microbiota in fattening Hu lambs [0.03%]
α-酮戊二酸及其钙盐对育肥湖羊生产性能、健康状况、瘤胃发酵和微生物群的影响
H W Duan,L Li,H B Ye et al.

Rumen microbes govern energy supply and nitrogen use in sheep. α-Ketoglutarate (AKG) links carbon and nitrogen metabolism and may support microbial synthesis, yet its in vivo effects on fermentation, digestibility, and antioxidant status i...
Review: Genetic and physiological regulators of parathyroid hormone and the vitamin D system in pigs [0.03%]

Calcium and phosphorus are essential for skeletal mineralisation and metabolism in mammals including pigs. Endogenous regulatory processes ensure a balance in mineral absorption, utilisation, retention, and excretion. Mineral homeostasis is...
A meta-analysis of 3-nitrooxypropanol effects on methane production and yield in beef cattle [0.03%]
3-硝基氧丙醇对肉牛甲烷产量和生产性能影响的meta分析
M H de Oliveira,R Zihlmann,A Bannink et al.
M H de Oliveira et al.
Beef cattle are a major source of enteric methane (CH4) emissions, a potent greenhouse gas. The feed additive 3-nitrooxypropanol (3-NOP) has been shown to reduce CH4 emissions by inhibiting methyl-coenzyme M reductase, an enzyme critical to...
A study of associations between the salivary metabolite composition, pH, and gastric ulcers in lactating sows [0.03%]
关于乳母猪唾液代谢物组成、pH值与胃溃疡关联性的研究
L C Salazar,E M Baxter,A B Lawrence et al.
L C Salazar et al.
Gastric ulcers are highly prevalent in the pig industry and are likely to cause discomfort or pain. However, there are no validated non-invasive methods to diagnose gastric ulcers in living pigs. Such diagnostics may help improve our unders...
Review: Colostrum production and intake- functional roles in piglet survival, future reproduction, and the challenge of genetic selection [0.03%]
