Abstract: (25476 Views)
In order to study the nutritive value of grades 1 and 2 wheat feed screening and macaroni wastes as energy resources, 360 21-day-old broiler chicks were divided into 36 groups of 10. In this experiment, each experimental levels of feedstuff was used at 0 (control group), 15, 30 and 45%. In addition, their apparent metabolizable energy (AMEn) was determined by Sibbald’s method. Daily feed intake of chicks fed by diets containing macaroni wastes and grade 1 wheat feed screening for 21 to 56 days of age was significantly lower than that in the control group (P<0.05). In contrast, body weight, daily weight gain and feed conversion had no significant differences during this period. However, in the total experimental period, the best feed conversion belonged to chicks fed with various levels of macaroni wastes and grade 1 wheat feed screening. Apparent metabolizable energy (AMEn) of macaroni wastes and wheat feed screening were 3700, 3270, and 2870 kcal/kg, respectively. According to the results of this experiment, it is possible to use macaroni wastes and grade 1 wheat feed screening at 45% and 30% levels in the diet of broiler chicks, respectively, without any undesirable effects on their performance.
