| 6 | Effects of Sustained-Release Calcium Hydroxide and Sustained-Release Hydrochloric Acid on Nutrient Di-gestion and Absorption of Rabbits显示文摘Rabbits with the body weight of(2. 0 ± 0. 5) kg were chosen,to study the effects of sustained-release calcium hydroxide and sustained-release hydrochloric acid on nutrient digestion and absorption of rabbits. The results showed that sustained-release calcium hydroxide promoted digestion and absorption of nutrients,especially calcium and crude protein. The digestibility of calcium and crude protein was increased from 89. 8% and 93. 8% to 41. 0% and 65. 2%,respectively. Sustained-release hydrochloric acid was adverse to digestion and absorption of nutrients,especially calcium and crude protein. The digestibility of calcium and crude protein were decreased from 55. 5% and 84. 9% to 28. 4% and 68. 7%,respectively. The promotion effects of sustained-release hydrochloride on digestion lasted for 3-4 d. Therefore,sustained-release calcium hydroxide promoted digestion and absorption of calcium and protein,while digestion and absorption of fat remained at a high level no matter what the condition was. Consequently,increasing the intake of fat would cause over nutrition. However,taking sustained-release hydrochloric acid would reduce nutrient digestion and absorption. | Chen Lingyu Zhuge Liuying Lin Zijun Tong Zhangfa Wei Tengyou | 2017 | Animal Husbandry and Feed Science2017，9，2： | 0 |
