Elemam MB, Fadelelseed AM, Abdoun K, Salih AM., Effect of deep stack feed supplement on hematology and serum biochemistry in lambs, Onl J Vet Res., 25 (6): 383-393, 2021. Authors report effects of 15%, 30% and 45% of deep stack litter supplement on hematology and serum biochemistry in four groups of 4 lambs each. Controls were not supplemented (0%). Deep stacking was prepared in an underground silo pit (2*2*2m) for 30 days. Jugular blood was taken at 0, 14, 45 and 90th days. Compared with controls, we found declines (P < 0.05) in mean corpuscular volumes (-12%), sodium (-3%) and triglycerides (-19%) but increased white blood cells (~19%). Both controls and supplemented lambs were affected similarly (P > 0.05) by periods of feeding so there was no significant difference between those groups. Our hematological data was within normal range of 21-35% reported for sheep. Compared with published data, we found normal hematology and serum biochemical values suggesting that our diets did not induce any metabolic or physiologic disorders. We find that up to 45% deep-stacked broiler litter ration was safe for lambs.
