Barley residual of a malt factory as a substitute of corn for pigs
The objective of this experiment was to determine the best level of corn by barley substitution in diets for pigs during growing and finishing period. The level of 0%, 25%, 50%, 75% and 100% substitution were compared using 120 Landrace x Large White pigs, with average initial and final weights of 22.63 kg ±0.40 kg and 96.59 kg ± 1.25 kg, respectively. Positive significant linear effects (P<0-01) were found for feed conversion ratio during the growing period (CÂC2) and for the total experiment period (CÂT2). The equations were: CÂC = 2.4384 + 0.0026X; R2 = O.71 and CÂT = 2.9359 + 0.0036X; R2 = 0.97. The crude protein digestible coefficient and digestible energy showed negative linear effects (P<0.05) as barley was increased in the diet. When intake and gain data were adjusted for a production function, it was found that the best level of corn barley substitution was 2.50%.
