Identification of oestrus cows based on vocalisation characteristics and machine learning technique using a dual-channel-equipped acoustic tag [0.03%]
基于发声特征和机器学习技术的发情 cow识别研究

Jun Wang et al.
Timely and accurate detection of oestrus in cows is an essential element of the good management of dairy farms. At present, the detection of cows in oestrus by acoustic means is impeded by the problems of filtering, incomplete feature selec...
Effects of OmniGen AF feed supplementation on glucocorticoids, blood leukocyte messenger RNA abundance, and energy metabolism in overstocked Holstein dairy cows [0.03%]
OmniGen AF添加剂对超高密度饲养荷斯坦奶牛糖皮质激素、血液白细胞mRNA丰度及能量代谢的影响
J M Huzzey,J P Jarrett,E D Sharman et al.
J M Huzzey et al.
The physiological consequences of overstocking require more investigation, and no research has explored whether dietary supplements could mitigate the anticipated negative physiological effects. OmniGen AF (OG, Phibro Animal Health Corporat...

C Toinon et al.
Early maternal deprivation has been shown to disrupt goat kids' social behaviour and stress-coping strategy, and has long-term effects in other species like cattle. We studied the long-term effects of early maternal deprivation on 18-month-...
On-farm evaluation of models to predict herbage intake of dairy cows grazing temperate semi-natural grasslands [0.03%]
用于预测乳牛在温带半自然草地上放牧时的家畜饲料摄入量模型的现场评估
S Perdana-Decker,E Velasco,J Werner et al.
S Perdana-Decker et al.
The objective of the present on-farm study was to evaluate the adequacy of existing models in predicting the pasture herbage DM intake (PDMI) of lactating dairy cows grazing semi-natural grasslands. The prediction adequacy of 13 empirical a...
Dietary inclusion of methanotrophic microbial cell-derived protein in the early postweaning period sustains growth performance and intestinal health of weaner piglets [0.03%]
甲烷营养型微生物细胞衍生蛋白对断奶仔猪生产性能和肠道健康的影响
Mette Skou Hedemann,Marie Rønn,Marleen Elise van der Heide et al.
Mette Skou Hedemann et al.
The global demand for sustainably produced protein feeds for animal production is increasing. Methanotrophic bacteria grow on methane and convert it into microbial cell protein (MCP) that has been shown to have high nutritive value for grow...
Relationship between milk urea content and important milk traits in Holstein cattle [0.03%]
荷斯坦奶牛乳尿素含量与重要乳成分性状的相关分析
R E Jahnel,I Blunk,D Wittenburg et al.
R E Jahnel et al.
Breeding cattle with low nitrogen emissions has been proposed as a countermeasure against eutrophication due to dairy production. Milk urea content (MU) could potentially serve as a new readily measured indicator trait for nitrogen emission...
A potent allele marker related to low bull conception rate in Japanese Black bulls [0.03%]
与日本黑牛低受精率相关的强力等位基因标记
M Kinukawa,M Ito,Y Uemoto et al.
M Kinukawa et al.
Over the years, there has been considerable variation in the bull conception rate (BCR) of Japanese Black cattle; moreover, several Japanese Black bulls with a low BCR of ≤10% have been identified. However, the alleles responsible for the ...
An increased weaning age and liquid feed enhances weight gain compared to piglets fed dry feed pre-weaning [0.03%]
断奶前喂液态饲料可提高仔猪的生长性能
K K Lyderik,J G Madsen,C Larsen et al.
K K Lyderik et al.
Increasing age and providing liquid creep feed could potentially increase the solid feed intake in pre-weaning piglets, which may in turn promote gut maturation and post-weaning feed intake, possibly lessening the severity of the growth-che...
Development and validation of a smart system for medullation and diameter assessment of alpaca, llama and mohair fibres [0.03%]
用于评估羊驼、 llama和山羊绒纤维髓质和直径的智能系统的开发与验证
M D Quispe,C C Quispe,L Serrano-Arriezu et al.
M D Quispe et al.
Medullated fibres, due to their higher resistance to bending and pressure, constitute a problem for the textile industry. Thus, having practical instruments to identify them is essential. Therefore, the aim of this research was to develop a...
Review: The challenge to integrate animal welfare indicators into the Life Cycle Assessment [0.03%]
评论:整合动物福利指标到生命周期评估中的挑战
L Lanzoni,L Whatford,A S Atzori et al.
L Lanzoni et al.
The transition to a more sustainable livestock sector represents one of the major challenges of our time. Life Cycle Assessment (LCA) is recognised as the gold standard methodology for assessing the environmental impact of farming systems. ...
