Assessing future economic and environmental impacts of selecting resilient dairy cows using integrated mechanistic and genetic modelling [0.03%]
整合机制和基因模型选择耐逆性奶牛的未来经济和环境影响评估
R Shi,A van der Linden,B Ducro et al.
R Shi et al.
Breeding for more resilient cows may help the global dairy industry to adapt to future climate change. However, the performance of selected cows in future environments cannot be directly assessed from historical data. Therefore, this study ...
Shortening the measurement period decreases precision in the determination of digestibility and nitrogen balance-related traits in growing bulls [0.03%]
缩短测定周期会降低对生长公牛消化率及氮平衡相关性状的测定精度
R Bellagi,G Cantalapiedra-Hijar,R Baumont et al.
R Bellagi et al.
Digestibility and nitrogen (N) balance (NB) are classically measured in animals held in digestibility stalls for several consecutive days. These measurements are essential references for the development of feed evaluation and animal phenoty...
Activity and synchrony patterns obtained by a tracking-by-detection algorithm as potential predictors of tail biting at pen and individual level in pigs [0.03%]
基于检测的跟踪算法获得的行为和同步模式可能作为预测猪栏和个体水平咬尾行为的潜在指标

C A E M Orsini et al.
Tail biting is a major welfare concern in pigs. Timely interventions may help to reduce its spread in an outbreak. However, tail biting is usually detected only at an injury stage. Therefore, early indicators are needed to predict outbreaks...
Short communication: First insights into response to selection for reducing methane emissions in dairy cows [0.03%]
短期通讯：首次探讨减少奶牛甲烷排放的选育反应
S Fresco,D Boichard,S Aguerre et al.
S Fresco et al.
Genetic selection against methane emissions is one of the levers to reduce the environmental impact of dairy production. Once genetic evaluation of methane emissions is available, the next step is to include this trait in breeding objective...
Review: Nutrition-based perinatal strategies towards antimicrobial-free systems in piglets [0.03%]
评论：基于营养的围产期策略朝着无抗仔猪系统发展
E Roura,P Bogere,X Liu et al.
E Roura et al.
The use of antimicrobials in pig production keeps increasing with the global demand for pork, causing a potential increase in the circulating pool of antimicrobial-resistant genes and other environmental issues. However, developing antimicr...
Supplementation with willow containing condensed tannins shifted nitrogen excretion from urine to faeces in yearling ewes [0.03%]
补充含有浓缩单宁的柳树饲料可改变周岁母羊氮排泄的比例使其由尿液向粪便转变
J P Thompson,O Cristobal-Carballo,T Yan et al.
J P Thompson et al.
Ruminants have poor nitrogen use efficiency, with 70% of total ingested nitrogen (N) excreted. Much of this excreted N is in the form of urinary urea which is easily hydrolysed to ammonia. Increasing ammonia production has negative impacts ...
Energy utilisation efficiencies of digestible starch and non-starch polysaccharide in Nile tilapia [0.03%]
尼罗罗非鱼对消化淀粉和非淀粉多糖的能量利用效率
B K Dey,M C J Verdegem,M A J Nederlof et al.
B K Dey et al.
The current trend of incorporating diverse plant-based and novel ingredients in fish diets is leading to higher dietary non-starch polysaccharide (NSP) levels, altering the dietary starch-to-NSP ratio. While tilapia lack NSP-digesting enzym...

Genome-wide association study in the Holstein cattle population highlights candidate variants for milk production traits [0.03%]
全基因组关联分析在荷斯坦奶牛群体中的应用揭示了牛奶生产性状的候选变异体
S Koncagül,A Ö Şen,M Yıldırır et al.
S Koncagül et al.
Understanding the genetic basis of production traits in dairy cattle is important for both improving productivity and its economic significance. Although genome-wide association studie has been widely used internationally to investigate the...
Energy metabolism and ruminal fermentation of prolific ewes in response to scheduled increase, relative to lambing, of dietary energy source and concentration [0.03%]
放奶山羊能量代谢和瘤胃发酵对分娩后阶段性增加日粮能量水平的响应
M Plante-Dubé,C Sylvestre,R Bourassa et al.
M Plante-Dubé et al.
In late gestation, to prevent metabolic disorders in prolific ewes, energy intake must align with increased energy requirements to support the growth of multiple fetuses. The present study was conducted to evaluate if providing a high-conce...
