Despite their predominance worldwide, few studies have been conducted to look at the impact of sheep production systems relying on transhumance practices in arid and continental conditions, on farm-level greenhouse gas (GHG) emissions. Usin...
Review: Bioavailability of trace elements in farm animals: definition and practical considerations for improved assessment of efficacy and safety [0.03%]
动物微量元素生物利用率的研究：定义及有效性和安全性评估的实践考量
D Brugger,B Wagner,W M Windisch et al.
D Brugger et al.
Currently, the authorisation procedure of trace elements as feed additives in the European Union according to Regulation (EC) No. 1831/2003 does not consider the bioavailability of trace element sources. This manuscript provides framework c...
Animal board invited review: Factors affecting the early growth and development of gilt progeny compared to sow progeny [0.03%]
从母猪后代到后备猪后代影响早期生长和发育的因素综述
U A Wijesiriwardana,J R Craig,J J Cottrell et al.
U A Wijesiriwardana et al.
Progeny born to primiparous sows farrowing their first litter, often called gilt progeny (GP), are typically characterised by their poorer overall production performance than progeny from multiparous sows (sow progeny; SP). Gilt progeny con...
Is a short concentrate-finishing period in lambs raised on alfalfa pasture effective at reducing fat indoles contents and lightening meat colour? [0.03%]
短期集中圈养能否降低紫花苜蓿放牧羊排酸期内源性脂肪吲哚含量及改善肉色？
Carlos Emanuel Eiras,Armelle Prunier,Karine Meteau et al.
Carlos Emanuel Eiras et al.
Pasture-feeding in lambs has been associated with dark-coloured meat and high meat contents of volatile indoles (skatole and indole), which may be responsible for sensory defects. The risk of off-flavours is even higher when lambs graze alf...

Monitoring the rate of change in inbreeding and genetic diversity within a population is important to guide breeding programmes. Such interest stems from the impact of loss in genetic diversity on sustainable genetic gain but also the impac...
