RESUMO
We studied the growth, feed intake, feed efficiency and protein efficiency ratio of groups of female Beagle puppies fed 16% or 22% crude protein rations to which 6% or 12% wheat bean was added at the expense of the total diet. The final neutral detergent fibre concentrations were 12%, 16%, 22% and 23% (dry matter basis). The addition of wheat bran to puppy rations, bringing the neutral detergent fibre up to 16% in a 21% crude protein diet had no deleterious effects on feed intake, feed and protein efficiency or growth in Beagle puppies. Over a sufficiently long period of time, the growth of this group did not differ from that of the controls (12% neutral detergent fibre, 23% crude protein) although it was higher at intermediate times. The effects of the high fibre (22 or 23% neutral detergent fibre) diets on growth, feed intake feed efficiency and protein efficiency ratio are consistent with an energy deficit resulting from the animals' inability to adapt fully to the dilution of their rations leading to lower growth, less efficient use of feed and, in the case of group 3 (22% crude protein, 22% neutral detergent fibre), a lower protein efficiency ratio. The protein efficiency ratio of group 4 (16% crude protein, 23% neutral detergent fibre) was higher than that of group 3, most likely the result of a more limiting amount of dietary protein leading to a more efficient use for growth by the animal. We have concluded that intermediate levels of neutral detergent fibre (up to 16%) were not deleterious even in puppy rations.(ABSTRACT TRUNCATED AT 250 WORDS)
