“…A few studies have been published on replacing barley grain with wheat DDGS (Charles et al 2012;Avila-Stagno, Chaves, Graham, et al 2013;AvilaStagno, Chaves, He, et al 2013;Graham et al 2013), while limited literature is available on the use of corn DDGS in sheep diets. Additionally, most studies have been conducted on sheep breeds raised in temperate climates.…”

Objective of this study was to evaluate the effect of partial replacement of soybean meal and barley grain with corn-dried distiller's grains with solubles (DDGS) on growth performance of Awassi lambs. Thirty lambs (3 to 4 months of age; 24.9 ± 1.93 kg; initial BW) were randomly assigned to three diets; (1) control diet (CON), (2) treatment diet containing 75 g DDGS/kg dietary dry matter (DM) (DDGS75) or treatment diet containing 150 g/kg DDGS/kg dietary DM (DDGS150). The study lasted for 63 days. Lamb BW and blood samples were measured on day 0, 21, 42, and 63 before the morning feeding. At the end of the feeding trial, 6 lambs from each treatment group were chosen at random and housed in metabolic cages to evaluate nutrient digestibility and N balance. Intakes, nutrient digestibility and N balance measures were similar (p > .05) among dietary treatments. Initial BW, final BW, ADG as well as feed efficiency were similar (p > .05) among the dietary treatment diets. Cost of gain reduced (p .05) in lambs fed DDGS150 compared with the CON and DDGS75 diets. Serum concentrations of urea N, glucose, total protein, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and albumin were similar (p >.05) among diets. Results demonstrated that inclusion the DDGS at 75 or 150 g/kg of diet DM could replace part of the soybean meal and barley grain without affecting nutrient intake and growth performance while it reduced the cost of feed and cost of gain.

Effects of dietary inclusion of dry distillers grains with solubles on performance, carcass characteristics, and nitrogen metabolism in meat sheep: a meta-analysis

We conducted a meta-analysis in this scientific study to determine the effects of feeding meat sheep dry distillers grains with solubles (DDGS). Thirty-three peer-reviewed articles that met our inclusion requirements and were published between 1997 and 2021 were examined. To calculate the variation in performance, fermentation, carcass features, and nitrogen efficiency between the DDGS and control (no DDGS) treatments, we used 940 sheep weighing an average of 29.1 ± 1.5 kg. We used a hierarchical mixed model to conduct a meta-regression, subset, and dose–response analysis, while taking into consideration categorical variables like breed (pure or cross-breed), and continuous factors, like CP, NDF, and DDGS inclusion rate. Our findings indicate that sheep fed DDGS had higher (p < 0.05) final body weight (51.4 vs. 50.4 kg), neutral detergent fiber digestibility (55.9 vs. 53.8%), and total-tract ether extract digestibility (81.7 vs. 78.7%) than sheep on a control diet. No effects were observed on DMI, CP, and rumen fermentation, but dietary DDGS tended to increase (p = 0.07) HC weight (25.53 vs. 24.6 kg) and meat (redness) color (16.6 vs. 16.3) among treatment comparisons. Dietary DDGS was associated with higher N intake (29.9 vs. 26.8 g/d), fecal N (8.2 vs. 7.8 g/d), and digestibility (71.9 vs. 68.5%). Urinary nitrogen was significantly (p < 0.05) affected linearly by increasing the intake of DDGS in the diet. Based on the dose–response analysis, dietary DDGS inclusion should not exceed 20% to avoid negative effects on performance, nitrogen metabolism, and meat color. Dietary protein from DDGS should not exceed 17% to prevent reduced TVFA concentrations. Breed strongly influenced (p < 0.05) RMD in performance, and inconsistent responses were observed between crossbreed and purebred sheep comparisons. Despite these inconsistencies, no publication bias was observed, but a high variance (Ω2) among comparisons-between-studies was detected. This meta-analysis showed evidence in support of the hypothesis that feeding meat sheep DDGS at a rate of 20% can improve their performance, digestibility, carcass weight, and meat color.
