Effects of Sea Buckthorn Pomace on Growth Performance, Organ Indexes, Serum Physiological Parameters and Intramuscular Fatty Acid Composition of Fattening Lambs
摘要
Abstract
The objective of the this study was to investigate the effects of dietary sea buckthorn pomace on growth performance, organ indexes, serum physiological parameters and intramuscular fatty acid composition of fattening lambs. Twenty?four 4?month?old Dorper×small thin?tailed crossed ram lambs [(25±1) kg] were selected and randomly divided into four groups with 6 sheep per group. Sheep in the four groups were fed the experimental diets which contained 0 ( control) , 10%, 20% and 30% sea buckthorn pomace, respectively. The experiment lasted for 50 days. The results showed as follows: 1 ) the slaughter body weight of lambs in 10% and 20% groups was significantly higher than that in control group and 30% group ( P<0.05) , the aver?age daily gain of lambs in 10% group was significantly higher than that in other groups ( P<0.05) , the average daily feed intake of lambs in 20% group was significantly higher than that in other groups ( P<0.05) , the ratio of feed to gain of lambs in 10% group was significantly lower than that in other groups ( P<0.05) . 2) The liv?er and spleen indexes of lambs in 30% group were significantly higher than those in other groups ( P<0.05) , and the reticulum stomach index was significantly lower than that in other groups ( P<0.05) . The large intes?tine and small intestine indexes of lambs in 10%, 20% and 30% groups were significantly higher than those in control group ( P<0.05) . 3) The serum high density lipoprotein ( HDL) content of lambs in 30% group was significantly higher than that in other groups (P<0.05), the atherosclerosis index (AI) of lambs in 10%, 20% and 30% groups was significantly lower than that in control group ( P<0.05) , the total antioxidant capac?ity ( T?AOC) and activities of glutathione peroxidase ( GSH?Px) and superoxide dismutase ( SOD) in serum of lambs in 10%, 20% and 30% groups were significantly higher than those in control group ( P<0.05) , the ac?tivities of aspartate transaminase ( AST) , alanine aminotransferase ( ALT) , lactate dehydrogenase ( LDH) and contents of creatinine ( CRE ) and urea nitrogen ( UN ) in serum of lambs in 30% group were significantly higher than those in other groups ( P<0.05) . 4) The proportions of linoleic acid, trans oleic acid, peanut four acid, total monounsaturated fatty acids (ΣMUFA) and total unsaturated fatty acids (ΣUFA) in longissimus dorsi of lambs in 10%, 20% and 30% groups were significantly higher than those in control group ( P<0.05) , while the proportions of oleic acid, total saturated fatty acids (ΣSFA ) and total polyunsaturated fatty acids (ΣPUFA) were significantly lower than those in control group ( P<0.05) . In conclusion, dietary supplemen?ted with sea buckthorn pomace is beneficial to improve the growth development and growth performance of fat?tening lambs, and the optimal supplemental level is 10% to 20%.关键词
