Free stall and feed bunk requirements relative to behavior, production and individual feed intake in dairy cows. J Dairy Sci. 1977; 60 :108–116.Friend TH, Polan CE, McGilliard ML (1977) Free stall and feed bunk
This figure is almost seven times the required volume of milk of a cow suckling a calf. This massive increase in milk yield has led to dairy cows having considerably increased nutrient requirements in order to maintain this level of production. A well-designed management system should adequately ...
Feeding Protein to Meet Dairy Cow Nutrient Requirements Can Result in Cheaper, Environmentally Friendly Rations 来自 ResearchGate 喜欢 0 阅读量: 19 作者:CC Stallings,ED Scientist,V Tech 摘要: Feed management in dairy cows to reduce nutrient consumption has been identified as being very effective in...
Among the PMO’s many provisions are requirements for laboratory testing of milk and dairy products for quality and safety. For every 2 billion servings of pasteurized milk or milk products consumed in the U.S., only about one person becomes ill, according to the Food and Drug Administration...
farm environment. The data for cows’ vital signs must be reported once every three hours, much higher than smart meters' once-per-day reporting. Since adding batteries would increase the cost and weight of the collars, power consumption requirements for the collars were therefore extremely high....
(1-year), randomised controlled trial (CONSORT 10 guidelines) to investigate the impact of increased living space (6.5 m2vs 3 m2per animal) on critical aspects of cow biology, behaviour and productivity. Adult Holstein dairy cows (n = 150) were continuously and randomly allocated to a ...

Requirements for Gestation The requirements for gestation were calculated based on protein accumulation in GEST, which is the difference between the gestation components (udder, uterus, and all the other components of the gravid uterus) observed in the pregnant cow and the gestation components of that...
Systems such as the CowManager SensOor monitor feeding time using head movements, whereas the Track A Cow more accurately describes feeding behavior or time around the feed bunk. A similar system recording cow proximity to the feedbunk was previously shown to be highly correlated with observed ...
In this study, the collection of rumen bacteriome data was performed from a large cohort of dairy cows (334 individuals) using Illumina HiSeq 2500 (PE250) based 16S rRNA gene amplicon sequencing of the V3-V4 region. All the cows were Holstein dairy cow, which is known as the most popular...
