Effects of dietary coarsely ground corn and 3 bedding floor types on broiler live performance, litter characteristics, gizzard and proventriculus weight, and nutrient digestibility
Poultry Science, 96(7), 2110–2119.
author keywords: broilers; corn particle size; live performance; gizzard; apparent ileal digestibility
MeSH headings : Animal Husbandry / methods; Animal Nutritional Physiological Phenomena; Animals; Chickens / growth & development; Chickens / physiology; Diet / veterinary; Digestion; Floors and Floorcoverings / methods; Gizzard, Avian / drug effects; Gizzard, Avian / growth & development; Housing, Animal; Male; Organ Size; Proventriculus / drug effects; Proventriculus / growth & development; Random Allocation; Zea mays / chemistry
