Effects of two Neepawa wheats (triticum aestivum, l.) fed at two protein concentrations with added dietary lysine on growth of turkey poults

Abstract

1. Two Neepawa wheats (145 and 210 g protein/kg) were tested in diets of two protein contents (220 and 280 g protein/kg) with or without added dietary lysine (0, 1, 2, 3, 4 or 5 g/kg) in a factorial experiment with young male turkeys (1 to 28 d). The protein contents of the diets were obtained by varying the proportions of the wheats and soyabean meal.

2. Irrespective of the Neepawa wheat used or lysine added, maximum growth was not obtained with diets containing 220 g protein/kg.

3. There was no response to lysine added to diets of 280 g protein/kg containing the 145 g protein/kg Neepawa wheat, but there was such a response in such diets containing the 210 g protein/kg wheat.

4. It is concluded that the Neepawa wheat containing 210 g protein/ kg, when supplemented with lysine, can replace soyabean meal in diets for young turkey poults.
