Mahdi AS, Yousif DH., Effect of red grape pomace and Saccharomyces cerevisiae supplements on hematology and biochemistry in lambs. Onl J Vet Res., 23 (11):1057-1069, 2019. Four groups of 5 Awassi male 2-3 month old lambs weighing 23.82 0.16kg were fed control diet supplemented 5% or 10% dried red grape pomace with or without 5g Saccharomyces cerevisiae daily for 126 days. Controls were fed 3% concentrate with wheat straw daily. Body weight, blood and serum samples were determined every 21 days for hematology and biochemistry. Compared with controls, our results suggest that red grape supplement with or without Saccharomyces cerevisiae boosted hemoglobin, red blood cells and packed cell volumes (P < 0.05). We found that the supplements had no effect on serum cholesterol or triglyceride but did enhance high and low-density lipoprotein after 105-126 days feeding (P < 0.05). Serum GSH increased during the last weeks of supplementation (P < 0.05). However, the most significant (P < 0.01) results of our study were highly significant reductions in serum Malondialdehyde at all stages of the experiment in lambs given supplements.
