Fluctuating asymmetry (FA) is the small, random difference between the left and right sides of paired traits and is widely used as an indicator of developmental instability and animal welfare. This study investigated whether heat stress (HS...
Effects of undernutrition and hydroxytyrosol supplementation in late pregnancy on cow-calf performance, metabolic and immune status, and newborn vitality in beef herds [0.03%]
妊娠后期母牛营养状况及水解蝶豆花素对其生产性能、代谢和免疫状态及新生犊牛活力的影响
L López de Armentia,A Noya,J Álvarez-Rodríguez et al.
L López de Armentia et al.
In semi-extensive cattle systems, cows may be exposed to undernutrition, which may reduce the productivity of beef herds. The objective of this study was to evaluate the effects of undernutrition and supplementation with hydroxytyrosol (HT,...
Postpartum magnesium status as an important risk factor for delayed and persistent subclinical hypocalcaemia in grazing Holstein cattle [0.03%]

Subclinical hypocalcaemia (SCH) is a significant metabolic disorder affecting dairy cattle. Research has shown that dairy cows experience three states of SCH, known as transient, delayed, and persistent SCH. Our objective was to identify po...
Genome-wide association study of fitness traits in local Alpine cattle breeds: insights into longevity, fertility, and udder health [0.03%]
适应性状的全基因组关联研究在本地高山奶牛品种中的应用：长寿、繁殖力和乳房健康的启示
A Oian,E Mancin,G Gomez Proto et al.
A Oian et al.
In recent decades, genetic research in cattle has largely prioritised cosmopolitan breeds and production traits, often overlooking functional and fitness-related characteristics such as longevity, fertility, and udder health. These fitness ...
An integrated individual-based model of transmission, clinical outcomes, and economic impact of Mycoplasma hyopneumoniae infection in a commercial pig fattening unit [0.03%]
猪支原体肺炎在商业育肥单元传播、临床结果和经济影响的整合个体基础模型
M Boeters,B Garcia-Morante,S Picault et al.
M Boeters et al.
Mycoplasma (M.) hyopneumoniae remains a major economic and health challenge for pig production worldwide, causing lung lesions and coughing that reduce production performance and farm profitability. However, the interplay between transmissi...
Dietary hydrolysed tannins regulate carcass performance and meat traits in Hu sheep through microbial regulation [0.03%]
通过微生物调节调控荷羊胴体性能和肉用性状的水解单宁饮食
S Zhu,T Liu,J Xu et al.
S Zhu et al.
Tannins improve ruminants' growth and production performance via promoting nitrogen utilisation or as antioxidants and antiparasitic agents. However, the metabolism and effectiveness of tannins on ruminal microbiota and biohydrogenation and...
Review: Understanding cattle social behaviour in modern penned production systems with AI technology: Are we tracking welfare indicators? [0.03%]
评论：利用人工智能技术理解现代圈养生产系统中家畜的社会行为：我们在追踪福利指标吗？
A Fuentes,S Han,J Liu et al.
A Fuentes et al.
Monitoring cattle social behaviour is fundamental for assessing animal welfare in modern penned production systems. Traditional observation methods are constrained by subjectivity, labour demands, and limited scalability, prompting increase...
Genetic parameters of larval weight and length in yellow mealworm under tropical conditions: heritability and implications for breeding programmes [0.03%]
热带条件下黄粉虫幼虫体重和体长的遗传参数：遗传率及其对育种计划的意义
C J Gómez-Rojas,G Martínez-Marín,H O Toledo-Alvarado et al.
C J Gómez-Rojas et al.
Understanding the genetic architecture of growth and larval productivity is essential for developing breeding programmes for Tenebrio molitor in tropical regions, where environmental conditions differ markedly from the temperate systems in ...
Challenging a mathematical model of amino acid metabolism in the small intestine, developed in pigs [0.03%]
对猪小肠氨基酸代谢数学模型的挑战
C J J Garçon,N Le Floc&#x;h,Y Mercier et al.
C J J Garçon et al.
A better understanding of the interplay between digestive processes and the metabolism of amino acids (AAs) in the small intestine (SI) is valuable for nutritional research. In a previous study, a conceptual model of AA fluxes in the SI was...
