- W2361256777 abstract "This experiment was conducted to explore the crude protein metabolism and requirement of 12 to 13-month-old Xiangzhong black cattle. Thirty healthy Xiangzhong black cattle with a similar body weight of( 273. 77 ±15. 97) kg,aged 12 to 13 months of age were selected and randomly divided into 5 groups with 6 replicates in each group. Beef cattle were fed 5 diets with different levels of crude protein which were formulated according to the expected weight gain 1. 0 kg / d of crude protein [China Feeding Standard of Beef Cattle( NY /T 815—2004) ]required for 70%( group Ⅰ),85%( group Ⅱ),100%( group Ⅲ),115%( group Ⅳ) and 130%( group Ⅴ),respectively. Feeding test and digestion and metabolism test were carried out to measure the growth performance and crude protein metabolism indexes of Xiangzhong black cattle,and to build the models for predicting the crude protein requirement. Pre-test period was 7 d and test period was 50 d. The results showed as follows: there was a high degree of positive linear correlation between average daily gain and crude protein intake or digestible crude protein intake( R2= 0. 926,R2= 0. 945); crude protein digestibility, crude protein deposition rate and crude protein biological value were( 66. 5 ± 5. 0) %,( 36. 6 ± 8. 7) % and( 54. 4 ±9. 3) %,respectively; crude protein digestibility was gradually increased as the increase of crude protein intake( P 0. 05),and crude protein deposition rate and crude protein biological value in groups Ⅳ and Ⅴ were significantly greater than those in groups Ⅰ and Ⅲ( P 0. 05); crude protein and digestible crude protein requirements for Xiangzhong black cattle could be estimated by the equations: CP = 5. 29W0. 75+ 430. 69 × DG; DCP = 2. 66W0. 75+ 377. 95 × DG. CP represented crude protein requirement( g / d); DCP represented the requirement of digestible crude protein( g / d); W0. 75represented the units of metabolic body weight( kg); DG represented daily gain( kg / d). The crude protein and digestible crude protein requirements for maintenance of Xiangzhong black cattle are 5. 29 and 2. 66 g /( kg W0. 75·d),respectively. Crude protein and digestible crude protein requirements for per kilogram gain are 430. 69 and 377. 95 g,respectively." @default.
