Effects of production time, die condition, and feed mill on the physical quality of commercial broiler diets

Publikováno v: Journal of Applied Poultry Research, Vol 33, Iss 3, Pp 100430- (2024)

SUMMARY: A variety of milling conditions can impact the physical quality (pellet durability index (PDI) and feed form (FF) composition) of broiler diets. Likewise, FF composition has been observed to affect broiler prehension and feed consumption pat

Effects of feeding varying proportions of pellets and fines on growth performance and carcass yield of broilers during a 63-day production period

Autor: K.W. McCafferty, J.L. Purswell

Publikováno v: Journal of Applied Poultry Research, Vol 32, Iss 2, Pp 100332- (2023)

SUMMARY: Pelleting is a common feed milling practice in the broiler industry due to its positive effects on broiler performance and feed handling characteristics. Milling conditions, ingredients, and transportation can all affect the formation and du
