Effects of dietary nanocrystalline cellulose supplementation on growth performance, carcass traits, intestinal development and lipid metabolism of meat ducks

摘要

Abstract The influence of nanocrystalline cellulose (NCC) supplementation on growth performance, carcass traits, intestinal development, and lipid metabolism was assessed in 600 one-day-old male meat ducks (Cherry Valley ducks) from 1 to 35?d of age. Diets were supplemented with 0, 200, 500, 800 and 1,500?mg/kg {NCC} during both the starter (1–14?d) and grower (15–35?d) phases. Each dietary treatment consisted of 8 replicate cages of 15 birds. Supplementation of {NCC} was associated with dose dependent increases in {BW} gain and feed intake (P?
