Influence of dietary corn distillers’ dried grains with solubles on nutrient digestibility, growth performance, and carcass traits in rabbits

Two experiments were performed to evaluate the digestibility and growth performance of New Zealand White rabbits fed corn distillers’ dried grains with solubles (DDGS). For the digestibility trial, 20 rabbits were housed in metabolic cages. The animals were distributed in two treatments, T1 (control...

Description
Summary:Two experiments were performed to evaluate the digestibility and growth performance of New Zealand White rabbits fed corn distillers’ dried grains with solubles (DDGS). For the digestibility trial, 20 rabbits were housed in metabolic cages. The animals were distributed in two treatments, T1 (control diet without inclusion of DDGS) and T2 (control diet + 300 g kg −1 DDGS). For the growth performance trial, 100 rabbits (50 males and 50 females) were assigned in a factorial design 2 × 5 (2 gender × 5 inclusions of DDGS) and five replicates. The treatments were composed of diets with inclusions of 0, 60, 120, 180, and 240 g kg −1 of DDGS. The rabbits were housed at 35 days old, and the experiment lasted 35 days. The DDGS showed high digestibility for protein (74.10%) and lipids (81.51%) and a high content of digestible energy (2979 kcal kg −1 ). In the second trial, growth performance and carcass yield and organ relative weights were evaluated. There were no interactions between gender and DDGS inclusions ( P  > 0.05). A linear decrease was observed for feed intake (FI) for the period from days 35 to 50 (FI, P  = 0.001) and FI and FCR from days 35 to 70 (FI, P  = 0.004; FCR, P  = 0.001) with the increasing levels of DDGS. Rabbits supplemented with 240 g kg −1 had lower ( P
