The purpose of this study was to analyse the influence of different external air temperature on changes in the air temperature of housing environment in the farrowing house for sows and consequent cha...
Effects of high air temperatures on milk efficiency in dairy cows
dairy cows milk production milk composition high air temperatures elevation housing breed cooling
2015/6/2
26 herds with 71 586 individual records were used. We tested a hypothesis that milk efficiency was influenced by the elevation of the farm, housing system, breed, area of altitude, and by the cooling ...

Evaluation of Methods for Determination of Bulk Density of Eight Kinds of Forage under Air-dry and Wet Conditions
Forage Dry Bulk Density Wet Bulk Density Ruminants
2016/4/13
The conditions of measurement for the determination of bulk density were evaluated to assess the bulkiness of 8 kinds of forage. The bulkiness of the forages was determined with 4 different sizes of f...
