Cortisol is a hormone associated with pain, fear, distress, or discomfort. We hypothesized that human interventions increase cortisol concentrations in dairy cow plasma. Therefore, the objective of this study was to determine the concentrat...
Adenomyosis and fibrosis define the morphological memory of the postpartum uterus of dairy cows previously exposed to metritis [0.03%]

This study evaluated the effect of feeding milk replacers (MR) differing in fat composition on plasma cholesterol of dairy calves. Forty-five individually housed male Holstein calves (2.3 ± 0.82 d; mean ± SD) were blocked by arrival day a...
Differential effects of 3-nitrooxypropanol supplementation on milk fatty acid profiles in 3 different dairy breeds [0.03%]
3-硝基氧丙醇对三种不同奶牛品种乳脂脂肪酸的影响不同

Gayani M S Lokuge et al.
3-Nitrooxypropanol (3-NOP) is a promising and approved antimethanogenic feed additive in dairy farming. The objective of this study was to evaluate breed-specific variation in milk fatty acids (FA) following 3-NOP supplementation. Milk FA c...

In a consumer-centric environment, food products are created and focused on the consumer's experience and desires. One important food product used around the world is butter. Consumers expect that when they take their butter out of the refr...
Prepartum skeletal muscle reserves and branched-chain volatile fatty acid supplementation have minimal effects in response to intravenous glucose tolerance tests in periparturient dairy cattle [0.03%]
产前骨骼肌储备和支链挥发性脂肪酸补充对围产期乳牛静脉葡萄糖耐量试验的反应影响甚微
K M Gouveia,L M Beckett,M N Flinders et al.
K M Gouveia et al.
Periparturient dairy cows experience metabolic adaptations to prepare for increased nutrient requirements of the fetus and the onset of lactation. Adaptations include increased peripheral tissue insulin resistance, which can be evaluated ex...
Genetic and nongenetic variation of multiple births in Austrian dual-purpose cows [0.03%]
奥地利兼用牛产多胎的遗传与非遗传变异分析
M Caccin,B Fuerst-Waltl,C Fuerst et al.
M Caccin et al.
In recent decades, a general increase in multiple birth (MB) rate has been reported in both dairy and dual-purpose cattle breeds. As there is evidence that MB has negative effects on economically important traits in dairy cows, the aims of ...
