Effects of bovine colostrum on performance, survival,and immunoglobulin status of suckling piglets during the first days of life
bovine colostrum supplement growth performance field trial nursery pig survivability
2015/9/15
Supplementation of bovine colostrum (BC) has shown to improve growth performance, intestinal development, and immune response in early-weaned pigs. Little is known about whether BC may have similar ef...

Phenotypic Relationship between Lactation Persistency and Change in Body Condition Score in First-lactation Holstein Cows
Body Condition Score Cow Lactation Persistency
2016/5/6
We examined the correlations between lactation curve shape, including persistency and changes in body condition score (BCS) during early-stage (0 to 30 days in milk (DIM)), nadir-stage (31 to 90 DIM),...
