玉米秸和大豆秸对生长獭兔的营养价值
Nutritional Values of Corn Stalk and Soybean Stalk for Growing Rex Rabbits
摘要
Abstract
This trial was carried out to evaluate the nutritional values of corn stalk and soybean stalk for growing Rex rabbits. Eighteen white growing Rex rabbits at the age of 60 days with an average weight of (1. 78 ± 0. 20) kg were divided into 3 groups with 6 replicates in each group and one rabbit per replicate in a completely randomized design. A basal diet was formulated to meet requirements for growing Rex rabbits and two trial diets were formulated by substituting 15% of the basal diet with corn stalk and soybean stalk, respectively. Total fecal collection method was applied in the digestion test. Both pre-trial and trial period was 7 d. The results showed as follows; 1) gross energy (GE) and contents of dry matter (DM) , crude protein (CP) , crude fiber ( CF) , neutral detergent fiber (NDF) , acid detergent fiber ( ADF) , acid detergent lignin ( ADL) , ether extract (EE) , crude ash, Ca, P and nitrogen free extract (NFE) of corn stalk were 15. 79 MJ/kg, 90. 06% , 5. 35% , 34. 74% , 65. 39% , 37. 43% , 2. 89% , 0. 88% , 8. 85% , 0. 50% , 0. 08% and 40. 26% , respectively, and those of soybean stalk were 15. 11 MJ/kg, 91. 39% , 5. 64% , 47. 11% , 65. 20% , 50. 10% , 10. 95% , 1. 05% , 8. 80% , 0. 42% , 0. 09% and 28. 80% , respectively. The apparent digestible energy of corn stalk and soybean stalk were 6. 84 and 4. 87 MJ/kg, respectively. 2) Apparent digestibility of GE, DM, CP, CF, NDF, ADF, EE, crude ash, Ca, P and NFE of corn stalk were 43. 33% , 34. 44% , 54. 77% , 21.02% , 27. 52% , 23. 58% , 85. 92% , 45. 47% , 32. 78% , 60. 05% and 53. 79% , respectively, and those of soybean stalk were 32. 18% , 21. 74% , 50. 72% , 15. 60% , 19. 78% , 12. 57% , 87. 16% , 56. 69% , 36. 00% , 66. 64% and 34. 93% , respectively. There are certain differences between the nutrient digestibility of corn stalk and soybean stalk for growing Rex rabbits, nutritional values of corn stalk is better than those of soybean stalk combined with the chemical analysis of feed ingredients.
