Mollenhorst and J.A.P. Heesterbeek and H. Hogeveen - 《Journal of Dairy Science》 被引量: 38发表: 2010年 Differential cell count as an alternative method to diagnose dairy cow mastitis Changes in relative cell proportions occurring in diseased mammary glands of dairy cows can be determined ...
In multiple species, we estimate that immune activation consumes about 1 g glucose/kg BW0.75 or about 2 kg glucose/day in an adult lactating dairy cow. Thus, an activated immune system reprioritizes nutrient partitioning away from the synthesis of economically valuable products.27th Tri-State ...
The comparison of results from 2 different studies permits a conclusion that Wielkopolskie and Podlaskie dairy farms are able to compete with farms from the 4 largest milk-producing countries in the EU. Although both regions can improve yields per cow, especially Podlaskie, both regions are likely...
The Pennsylvania State Extension Dairy Team IOFC tool (http://extension.psu.edu/animals/dairy/business-management/financial-tools/income-over-feed-cost/introduction-to-iofc) was used to collect data from 95 Pennsylvania lactating dairy cow herds from 2009 to 2012 and to determine the IOFC ...

The purpose of the Economic Assessment Tool is to facilitate the estimation and demonstration of the wide variety of costs incurred during this critical period of time and to present a new metric for evaluating transition dairy cow performance, The Vital 90 Days Cost per Calving. 展开 会议名称...
Foldable container house is composed of a base, a left side wall, a right side wall, a front door wall, a rear end wall, and a roof. The base and each wall are pivotally connected by hinges, and between the walls, each wall upper end and the roof are...
Recent improvements in dairy cow fertility and female reproductive technologies offer an opportunity to apply greater selection pressure to females. This means there may be greater incentive to obtain genomic breeding values for females. We modeled the impact of changes to key parameters on the net ...
