Evaluation of Riboflavin Requirement of Different Sexual Beijing Ducks Aged from 1 to 21 Days
摘要
Abstract
This experiment was conducted to evaluate riboflavin requirements of different sexual Beijing ducks aged from 1 to 21 days. A 2 x9 two-factor completely randomized design containing two kinds of sex (male and female) and nine dietary riboflavin levels (1. 2, 3. 2, 5. 2, 7. 2, 9. 2, 11. 2, 13. 2, 15. 2 and 41. 2 mg/kg) was used in this experiment. A total of 360 one-day-old male Beijing ducks and 360 one-day-old female Beijing ducks were randomly divided into 9 groups with 5 replicates in each group and 8 ducks in each replicate, respectively. The results showed as follows; sex significantly affected average daily weight gain (ADG) and feed/gain (F/G) of Beijing ducks aged from 1 to 21 days (P <0. 05) , while did not significantly affect average daily feed intake (ADFI) , plasma riboflavin level, and activities of alanine transarninase ( ALT) , aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in plasma (P >0. 05). Dietary riboflavin level significantly affected ADG, ADFI, F/G, plasma riboflavin level, and activities of ALT, AST and LDH in plasma of Beijing ducks aged from 1 to 21 days (P <0. 05). According to broken-line regression analysis, the riboflavin requirements of Beijing ducks aged from 1 to 21 days for ADG, ADFI, F/G and plasma riboflavin level were 3. 31, 3. 24, 5. 20, 3. 82 mg/kg for male and 3. 27 , 3.19, 3. 33 , 3. 84 for female, respectively.关键词
