“…Concurrent with previous studies that were reported in our lab (Obeidat et al 2012;Obeidat Abdullah, et al 2016;Obeidat, Mahmoud, et al 2016;Oberidat 2017), this study proved that corn DDGS, as agro-industrial by product, is cheaper and would be more economical to feed growing Awassi lambs compared with the other ingredients such as barley grain and soybean and as a result it showed the benefits of using corn DDGS in the ration. The inclusion of DDGS at 75 and 150 g/kg of dietary DM reduced the cost of feed by 7.5 and 15% than the control diet.…”

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.

“…Hassan and Mohammed [ 14 ] found that DM intake was not affected by yeast addition to different roughage to concentrate ratios while CP intake increased when diets contained less fiber. Consistent with these results, intake did not change by adding SC to diets with different roughage to concentrate [ 15 ] and when added to concentrate diets [ 16 ] in male lambs. On the contrary, Hansen et al .…”

Aim:The aim of this study was to evaluate the effect of feeding low (LO)- or high (HI)-fiber diets supplemented with Saccharomyces cerevisiae (SC) on nutrient intake, digestibility, nitrogen balance, rumen fluid pH, and serum concentrations of glucose and urea nitrogen in Awassi female lambs in a 2×2 factorial arrangement of treatments.Materials and Methods:Experimental diets were as follows: (1) LO-fiber diet with no SC supplementation (−LO), (2) LO-fiber diet supplemented with SC (+LO), (3) HI-fiber diet with no SC supplementation (−HI), or (4) HI-fiber diet supplemented with SC (+HI). Eight female lambs were used in a replicated 4×4 Latin square design with 15-day experimental periods (10-day adaptation period and 5-day collection period).Results:A fiber×SC interaction (p≤0.05) was detected for dry matter (DM) and crude protein (CP) intake among diets showing greater DM and CP intake for +LO diet compared to +HI group supplemented with SC, whereas −LO and −HI were intermediate. A fiber×SC interaction (p=0.05) was also detected for the neutral detergent fiber (NDF) intake among diets. Intake of NDF was greater for the –HI diet compared with +LO and –LO diets. Similarly, NDF intake was greater for +HI diet than –LO diet. A tendency (p=0.07) for a fiber×SC interaction was detected for acid detergent fiber (ADF) intake among diets as well. ADF intake tended to be greater for HI-fiber diets. No difference was observed in the rumen fluid pH for lambs fed with the different diets. No fiber×SC interactions were detected for the digestibility of DM, CP, NDF, and ADF among dietary treatments. Digestibility of DM was greater (72.9 g/100 g vs. 67.1 g/100 g; p=0.0002) for LO versus HI fiber. However, NDF and ADF digestibilities were greater (60.8 and 61.9 g/100 g vs. 55.8 and 52.7 g/100 g for NDF and ADF digestibility, respectively; p≤0.01) for the HI-fiber than the LO-fiber diets.Conclusion:Results obtained in the current study indicate that SC supplementation has a minimal effect on the performance of Awassi female lambs fed with varying fiber levels.

“…The inclusion of agro-industrial by-products as an alternative to straw, protein sources, and cereal-based concentrates is a promising solution to this problem [5]. Due to their low cost and comparable efficiency in feeding, the usage of agro-industrial by-products in ruminant nutrition has increased, particularly in the last years [6,7].…”

“…Due to the increased international demand for these feeds, their prices have increased significantly, which has led to increased pressure on sheep producers. Researchers are therefore interested in the use of cheap alternative feeds (AF) in livestock diets, such as bread by-products (BB), carob pods (CARP) [8], olive cake (OC) [7], and dried distillers grains with solubles (DDGS) [9,10]. In addition, the use of these feeds would reduce pollution for the environment if it remains without disposal.…”

Simple SummaryAlternative feeds have been used to feed animals for decades by replacing traditional feeds to increase the profit of raising livestock. In this study, alternative feeds (dried distillers grains with solubles, carob pods, olive cake, and bread by-product) were fed to Awassi ewes and ewe lambs at 0, 200, and 400 g/kg. Chemical composition was similar among diets. Feed intake, body weight change, and milk yield did not differ among diets. Cost of milk production decreased in alternative feeds containing diets, with no negative effect on health, welfare, and productivity.AbstractTwo experiments were done to assess the effects of alternative feeds (AF; dried distillers grains with solubles, carob pods, olive cake, and bread by-product) on lactating performance of ewes and digestibility and nitrogen (N) retention of lambs. Diets were: no AF (CON); 200 g/kg AF (AF200); and 400 g/kg AF (AF400). In Experiment 1, 27 Awassi ewes were randomly distributed into three groups, and each was fed one of the diets described before (9 ewes/diet). Evaluation of milk composition and yield was performed at the beginning of the experiment and on days 18, 36, and 54. In Experiment 2, 18 Awassi lambs were allocated to the same diets (6 ewe lambs/diet) during a 21-day trial (14 days housed individually in shaded pens and 7 days in metabolic cages). In Experiment 1, no differences in body weight (BW) of the ewes and their lambs were detected. With the exception of neutral detergent fiber intake, which was lower in the AF-containing diets compared with CON, dry matter, crude protein, and acid detergent fiber intake were not affected by dietary treatment. Milk yield and composition was comparable among diets, and the cost of milk production was lower in AF compared to CON diet. In Experiment 2, nutrient digestibility and N retention were not affected by the diet. Results showed the possibility of including different AF in ewe and lamb diets to mitigate production cost without negatively affecting intake, milk yield, and composition, digestibility, and animal welfare and health.
