Abstract

The impact of dietary fiber content on voluntary feed intake, digestion and caecotrophy production of muskrat was studied. Eight of adult male muskrat with body weight of (1 368±121) g were independently raised in single cage, freely access to diet and drinking. The experiment was divided into three periods, each feeding a diet with a fiber content was an experimental period, and feeding 8 animals at the same time in each period. Pellet diets with fiber contents of 17.34% (diet 1), 21.57% (diet 2) and 25.67% (diet 3) were fed, respectively. The voluntary feed intake, nutrient apparent digestibility of diets, and production of feces and caecotrophy were measured. Each period of experiment lasted for 23 days, including 15 days for adaptation and 8 days for sample collection. The results showed as follows 1) for the three diets, the dry matter (DM) voluntary feed intake were (51.44±4.78) g/(d·rat), (51.79±3.46) g/(d·rat) and (52.04±2.65) g/(d·rat), respectively; the apparent digestibility of DM was (56.75±1.72)%, (54.76±0.50)% and (54.44±0.61)%, respectively. 2) Compared with diet 1, the digested amounts of crude protein (CP), energy and phosphorus in diet 2 decreased by 8.13% (P<0.01), 8.68% (P<0.01) and 13.33% (P<0.01), respectively, while that of cellulose and hemicellulose increased by 31.06% (P<0.01) and 7.25% (P<0.01), respectively; in diet 3, the digested amounts of CP, energy and phosphorus decreased by 12.92% (P<0.01), 11.13% (P<0.01) and 20.00% (P<0.01), respectively, and that of cellulose and hemicellulose increased by 60.61% (P<0.01) and 9.84% (P<0.01), respectively. 3) The DM yield of caecotrophy (DM basis) in three diets were (8.05±0.73) g/(d·rat), (8.29±0.55) g/(d·rat) and (8.36±0.44) g/(d·rat), providing organic matter (OM) by (6.88±0.86) g/(d·rat), (6.75±0.78) g/(d·rat) and (6.52±0.87) g/(d·rat), CP by (2.16±0.23) g/(d·rat), (2.12±0.27) g/(d·rat) and (2.03±0.76) g/(d·rat), and energy by (108.07±2.44) J/(d·rat), (104.36±2.32) J/(d·rat) and (104.12±1.99) J/(d·rat), respectively. The caecotrophy of the three diets provided total amino acids by (387.75±3.54) mg/d, (346.49±5.98) mg/d and (297.30±3.60) mg/d, lysine by (21.19±1.34) mg/d, (19.17±1.34) mg/d and (17.43±1.86) mg/d, and methionine by (26.65±1.52) mg/d, (19.83±1.92) mg/d and (16.14±1.37) mg/d, respectively. It is concluded that there are no significant effects of dietary fiber content on DM intake and apparent digestibility of muskrats, but dietary fiber content reduces digested amounts of CP, energy and phosphorus, and increases that of cellulose and hemicellulose; the content of digestible OM and digestible energy in caecotrophy of adult muskrat are not affected by dietary fiber content, but CP and amino acids contents are affected. Caecotrophy is an important source of nutrition for muskrat.
