Abstract

This experiment was conducted to investigate the requirements of energy and protein of Shanbei white cashmere wether goats so as to provide data for establishing them. Thirty-six healthy one-year-old Shanbei white cashmere wether goats with similar body weight were randomly divided into 9 groups according to a 3×3 (energy×protein) completely random experiment design, and each group had 4 replicates with 1 goat per replicate. digestible energy (DE) level in diet was formulated at 100%, 110% and 120% of NRC (1981) recommendation, respectively; and crude protein (CP) level was formulated at 90%, 110% and 130% of NRC (1981) recommendation, respectively. The pretest lasted for 7 days, and the test lasted for 46 days. The results showed as follows: 1) energy level in diet had extremely significant effects on dry matter intake (DMI) and average daily gain (ADG) (P<0.01), and protein level significantly affected DMI (P<0.05); there was significant interaction on DMI between energy and protein levels in diet (P<0.05). 2) Digestible nitrogen (N) in low energy group was significantly lower than that in medium and high energy groups (P<0.05); N intake, digestible N, retained N, N apparent digestibility in low protein group were extremely lower than those of medium and high protein groups (P<0.01). 3) Gross energy (GE) digestibility and metabolic rate were extremely significantly increased with energy level improving (P<0.01); metabolic rates of GE and DE in high protein group were significantly lower than these in low protein group (P<0.05); There was significant interactions of energy×protein on GE digestibility, GE metabolic rate and DE metabolic rate (P<0.05 or P<0.01). We establish regression equations of energy and protein requirement of one-year-old Shanbei white cashmere wether goats, the proper range of DE and ME levels in diet are 8.80 to 10.61 MJ/kg and 7.34 to 8.76 MJ/kg, respectively, and the appropriate CP and digestible CP levels are 10.00% and 7.34%, respectively.

Key words： Shanbei white cashmere goat; one-year-old wether goats; energy; protein; requirement
