Nonruminant Nutrition: Sow & Gilt Nutrition
A study was conducted to investigate how the allocation of energy to growth and maintenance differs between rainbow trout and Atlantic salmon and how the diet affects energy allocation. Rainbow trout and Atlantic salmon were handfed to satiation four isoenergetic diets (DE = 20 MJ/kg) with different digestible protein/digestible energy ratios (DP/DE), i.e., 24, 22, 20, and 18 g/MJ, achieved thr...

متن کاملNonruminant Nutrition: Sow Feeding
Continuous milking (CM) of bST-supplemented primiparous cows results in production losses of 20 to 25%, suggesting mammary growth was inhibited. We hypothesized continuous (throughout late gestation and early lactation) bST supplementation and/or early-lactation increased milking frequency (IMF) would alleviate production losses in CM glands through improved mammary epithelial cell (MEC) functi...
متن کاملConsequences of selection for lean growth and prolificacy on piglet survival and sow attribute traits
Pig breeding programs focus on growth and carcase composition traits in the growing pig as well as higher reproductive performance of sows leading to considerable genetic gain in these traits. These changes in genetic potential have consequences for piglet survival and husbandry requirements of sows. For example, comparison of body composition and physiological state of piglets from boars born ...
متن کاملNutrition and Management Strategies to Optimise Performance of the Modern Sow and Boar
One of the major achievements in pig production over the last thirty years has been the improvement in sow productivity from about 16 to 22 piglets reared per sow per year (Table 1). Interestingly, this achievement has not come about by large increases in the number of piglets born alive per litter, but more by improvements in nutritional knowledge and dietary formulation, management, husbandry...
