The dairy industry has profound economic importance, and individuals earning postsecondary degrees within dairy science-related fields are future industry leaders. Yet, enrollment at universities is declining and there is a labor shortage w...
How dairy heifers initially respond to freestalls: The effect of neck-rail placement [0.03%]
犊牛最初对奶牛舍自由栏的反应：颈杠高度的影响
Marek Gaworski,Kathryn McLellan,Marina A G von Keyserlingk et al.
Marek Gaworski et al.
Dairy heifers are often kept on open packs early in life and later transitioned to freestalls. The neck rail in freestalls acts as a barrier intended to prevent animals from entering too far in the stall, with the aim of improving stall cle...
A methodological approach to assess the ropy character of stirred acid dairy gels based on the measure of adhesiveness [0.03%]

Silvette Ruiz-Ramírez
In this study, a thermostable β-galactosidase from Lactobacillus helveticus OSU-PECh-4A has been isolated through diafiltration and size-exclusion chromatography. The enzyme consists of a heterodimer with a molecular mass of 110 kDa, with ...
Dairy cow performance and nutrient utilization when offered high or low digestibility grass silages at 2 levels of total diet crude protein [0.03%]
当以高低消化率的草青贮饲料和两种水平的粗蛋白总量日粮饲喂奶牛时，奶牛的生产性能和养分利用率如何？
