hydrolyzed feather meal, range cows, lactation
Sixty-eight cows calving in March and April grazing dormant winter range were used to evaluate hydrolyzed feather meal a protein supplement during early lactation. Within a week after calving cows were fed either a soybean meal or feather meal-corn supplement that provided approximately .83 Ib. crude protein per cow daily. Cow weight and condition score changes from calving until early May and percentage of cows cycling at the beginning of the breeding season in early June were similar between supplement groups. Calf average daily gains from birth until May were not affected by supplement fed to cows. In this study, supplementing lactating cows with hydrolyzed feather meal resulted in similar performance as supplementing with soybean meal.
