Abstract

This study was conducted to determine the effects of different diet forms on growth performance and nutrient utilization of Hepu geese. Seventy-two Hepu geese at age of 28 d were randomly blocked into 3 diet groups (3 replicates per group and 8 geese per replicate, half male and half female). Diet A was composed of concentrate+fresh Wedelia chinensis; diet B was mash feed composed of concentrate+Wedelia chinensis powder; diet C was pelletized feed composed of concentrate+Wedelia chinensis powder. The weight ratio of concentrate and Wedelia chinensis in diet A was 1∶2 (air-dry∶fresh) in the first period (28~48 d) and 1∶3 in the second period (49~69 d). The amount of Wedelia chinensis powder used in diets B and C was equal to the air-dry matter content of fresh Wedelia chinensis in diet A. The method of 4 mol/L HCl AIA was used for the determination of nutrient digestibility in geese. The experiment lasted for 42 d. Results showed that the average daily concentrate intake (ADCI) was increased in the first period but no difference was found in whole period (P>0.05). The ADCI of geese in 3 diets in whole period was 208.38, 207.22 and 205.73 g, respectively; average daily gain (ADG) was 56.07, 62.42 and 63.44 g, respectively; F/G was 4.28, 3.32 and 3.24, respectively. No significant difference was found on ADCI among 3 diets (P>0.05), however, the ADG and F/G in diets B and C were significantly better than those in diet A (P<0.05), but no significant difference occurred between diets B and C (P>0.05). The digestibility of energy, acid detergent fiber, neutral detergent fiber and hemicellulose in diets B and C were significantly better than those in diet A (P<0.05) just except that dry matter, crude protein and P in first period and crude protein, Ca and P in second period, which were not different among 3 diets (P>0.05); diets B and C also had better dressing percentage and percentage of abdominal fat than diet A (P<0.05). Therefore, the feeding efficiency of diets B and C was much better than that of diet A, so the better way to use Wedelia chinensis for geese feeding should be to dry fresh Wedelia chinensis and make it into powder.
