Effects of Supplemented of Sugar Beet Pulp on Water Metabolism of Yanqi Horse
摘要
Abstract
This experiment was conducted to study the effects of supplemented of sugar beet pulp on water me-tabolism of Yanqi horse. Twelve Yanqi horses were randomly divided into three groups according to perform-ance, body weight [(349.33±20.47) kg], body measurement and age. The groups were referred as one con-trol group and two experimental groups, and each group with 4 horses. Horses in the control group, experi-mental groupⅠand experimental groupⅡwere supplied with 0, 0.6, 1.2 kg/d of sugar beet pulp on the con-dition of feeding the same basal diet and roughage ( oat straw) . The pre-test period lasted for 15 days and the trial lasted for 5 days. The results showed as follows:1) compared with the control group, the water intake of the experimental groupsⅠ andⅡ were increased by 8.74% ( P>0.05) and 20.80% ( P<0.05) , respectively. However, there were no significant changes in the feces water content and urine excretion of the horses among all groups ( P>0.05) . Compared with the control group and the experimental group Ⅰ, the retention of water of the experimental group Ⅱ was increased by 27.23%(P<0.05)and 33.83%(P<0.05), respectively. 2) Compared with the control group, the antidiuretic hormone level in plasma of experimental groups Ⅰ and Ⅱwas increased by 14.65% ( P>0.05) and 45.93% ( P<0.05) , and also the adrenocorticotropic hormone level was increased by 22.02% ( P<0.01) and 24.06% ( P<0.01) , respectively. 3) There were no significant chan-ges in the levels of aldosterone, cortisol, angiotensin Ⅱ, atrial natriuretic peptide in plasma, and the concen-trations of K+, Na+and Cl-in blood supplemented with sugar beet pulp ( P>0.05) . Therefore, the retention of body water, the levels of antidiuretic hormone and adrenocorticotropic hormone level in plasma of Yanqi horse are significantly increased by supplementary feeding 1.2 kg/d of sugar beet pulp, which plays a positive role in the water metabolism of the body.关键词
