Abstract | ||||
The effect of using Acid Pack 4-Way (AP4W) as a growth promoter and/or sieving process of ground barley on improving the utilization of local barley in broiler diets were studied. Two hundred forty unsexed one-day old Arbor Acres broiler chicks were raised under the same management condition during 7 weeks experimental period. They were divided into ten triplicate groups. Ten starter-grower and ten finisher diets were formulated in which the control diets were composed mainly from yellow corn (YC) and soybean meal. Ground barley (GB) or sieved ground barley (SGB) were used on the expense of YC in the control diets in two substitution levels of 25 and 50%. The diets were assigned to be without or with the addition of a biological product named AP4W. The chicks were fed on the starter-grower diets up to 4 weeks of age, then, they were switched on finisher diets up to 7 weeks of age. A digestibility trial was conducted at the end of the starter period of the fattening experiment for measuring digestion coefficients and feeding value of the experimental diets. At 7 weeks of age, representative chicks were taken randomly from each treatment for measuring carcass characteristics. The results could be summarized in the following points: 1. The digestibility trial showed that sieving barley and supplementing barely with AP4W had an appreciable effect in improving the digestibility coefficients of nutrients and the calculated metabolizable energy value of the barley-containing diets. | ||||
