Abstract

The needs for animal protein consumption is increasing in line with the increasing population growth. Various attempts have been made to meet the needs including by raising broiler. In order that broiler achieve optimal productivity, a proper ration feeding both in quality and in quantity is crucial. One of such alternative feed supplies is sorghum, which is easily found throughout Indonesian regions and has nutritional substance comparable to corn at a relatively cheaper price. Therefore, this research was conducted to find out the effects of the provision of sorghum as maize substitution on the carcass and non-carcass percentage of six-week broiler, with provision level of up to 28%. This study uses 45 broilers of CP-707 strain. The method used is CRD (completely randomized design) with 5 treatments and 3 replications. The treatment included rations with no sorghum addition (R0), ration with 7% sorghum addition (R1), ration with 14% sorghum addition (R2), ration with 21% sorghum addition(R3) and ration with 28% sorghum addition (R4). The variables observed in this study were weight, carcass weight, carcass percentage, non-carcass weight and non-carcass percentage. Based on the results, it is concluded that the addition of sorghum into the poultry ration in all treatments has no effect on carcass weight, percentage of carcass, non-carcass weight, and percentage of non-carcass of the six-week broiler, but the addition of sorghum at the level of 28% reduced the weight and is significantly different statistical-wise (P <0.01). To save the cost of poultry feed in broiler farms, it is recommended that farmers use sorghum at the level of 21% as an alternative substitute of corn.

Abstract

The aim of this research was to determine the effect of different density of cages on the physical composition of the breast carcass and thighs of CP 707 broiler chickens. Cage and density of cages are important elements in the business of chicken farming. Cage density that is too high or too low can affect the temperature and humidity of the air in the cage and will ultimately affect the growth of the carcass. This study uses a completely randomized design (CRD) with 3 treatments. The treatments of P1 were 8 heads/m2, P2 density was 10 heads/m2, and P3 12 heads/m2 each treatment was repeated 3 times. The parameters observed were the physical composition of the carcass of the chest, upper thigh and lower thigh. The data obtained were analyzed by variance, if the data obtained were significantly different (P <0,05), it would be continued with the multiple distance test from Duncan. The results showed the density of the cages of 8,10, and 12 tails/m2 did not affect the physical composition of the carcass of the thigh both upper and lower thighs, but the density of the cage of 12 tails/m2 significantly affected the physical composition of the carcass of the chest especially the meat and chicken breast bones CP 707 broiler.
