The regulation of adipose deposition in broiler chickens is an important factor for production efficiency to poultry producers and health concerns to customers. Although vitamin A and its metabolite [all-trans retinoic acid (atRA)] have bee...
Longitudinal measures of labour time-use on pasture-based dairy farms, incorporating the impact of specific facilities and technologies [0.03%]
兼顾特定设施和科技影响的草地型乳品农场的纵向劳动时间使用度量标准

The seasonal workload on pasture-based dairy farms, combined with increased herd sizes, have led to an increased focus on farm labour time-use and techniques that can reduce farm labour demand. The objective of this study was to measure lab...
Performance and enteric methane emissions from housed beef cattle fed silage produced on pastures with different forage profiles [0.03%]
不同牧草结构的草地生产青贮料对舍饲肉牛的生产性能和肠道甲烷排放的影响

Methane (CH4) produced by ruminants is a significant source of greenhouse gases from agriculture in the United Kingdom (UK), accounting for approximately 50% of the emissions in this sector. Ration modification is linked to changes in rumen...
Effects of the addition of non-fibre carbohydrates with different rumen degradation rates in dairy cow high-forage diets using the Rumen Simulation Technique [0.03%]
不同降解率的非纤维碳水化合物添加剂对高粗料乳牛瘤胃内发酵的影响——用瘤胃模拟技术研究

M E Hanlon et al.
Nutrient synchronisation of protein and carbohydrates is a promising practice to improve ruminal nutrient utilisation. However, dietary sources supplying these nutrients can vary in ruminal nutrient availability due to differing degradation...
Animal board invited review: The contribution of adipose stores to milk fat: implications on optimal nutritional strategies to increase milk fat synthesis in dairy cows [0.03%]
动物邀请综述：牛脂肪组织的脂质贮备对乳脂合成的贡献及营养调控策略

DM intake (DMI) for individual pens of cattle is recorded daily or averaged across each week by most commercial feedlots as an index of performance. Numerous factors impact DMI by feedlot cattle. Some are available at the start of the feedl...
Effects of genomic estimated breeding value and dietary energy to protein ratio on growth performance, carcass trait, and lipogenic gene expression in Hanwoo steer [0.03%]

"Genome-based precision feeding" is a concept that involves the application of customised diets to different genetic groups of cattle. We investigated the effects of the genomic estimated breeding value (gEBV) and dietary energy to protein ...
Milk metabolites can characterise individual differences in animal resilience to a nutritional challenge in lactating dairy goats [0.03%]
奶代谢产物能够表征产奶山羊营养挑战下的个体抗逆性差异

A Ben Abdelkrim et al.
The aim of this study is built in two phases: to quantify the ability of novel milk metabolites to measure between-animal variability in response and recovery profiles to a short-term nutritional challenge, then to derive a resilience index...
Negative dietary cation-anion difference in prepartum dairy cow diets: a pragmatic study in two commercial dairy farms [0.03%]

Pragmatic studies, evaluating the effectiveness of an intervention under its usual conditions, are less commonly reported than the explanatory trials. For instance, the effectiveness of prepartum negative dietary cation-anion difference (DC...
Improved cattle behaviour monitoring by combining Ultra-Wideband location and accelerometer data [0.03%]
