Abstract

This study aimed to determine the effect of infertile eggs in the feed on slaughter weight, carcass quality and non-carcass quality in super native chickens. A total of 40 super-male chickens aged eight weeks were used in this study. The design of this study used a completely randomized design with a directional pattern with 4 treatments and 5 replications. The treatments in this study included: P0 (100% basal feed without additional infertile eggs); P1 (basal feed 96,7% + 3,3% infertile eggs); P2 (basal feed 93,4% + 6,6% infertile eggs) and P3 (basal feed 90,1% + 9,9% infertile eggs). The data were using analysis of variance (ANOVA), if significant results were obtained, they would be tested using Duncan's Multiple Range Test (DMRT). The results showed that the use of infertile eggs into the feed up to a level of 9.9% could increase the slaughter weight, carcass weight and carcass percentage (P<0.05). The addition of infertile eggs up to the level of 9.9% can also reduce the percentage of non-carcasses in super native chickens (P<0.05). The conclusion of this study is that infertile eggs can be used as feed ingredients for feed up to a level of 9.9% to increase slaughter weight, carcass weight, carcass percentage and can reduce the percentage of non-carcass in super native chickens.

Abstract

This research aims to examine the correlation between digestible crude protein (DCP) and digestible crude fiber (DCF) on methane gas production from fermented rice straw using urea and urine. The material in this study was used included eight indigenous rams aged ± 1.5 years with a weight of ± 20 kg. The feed provided consisted of concentrate and rice straw fermented with urea (P1) and rice straw fermented with urine (P2). Feed was given twice daily, and water was provided ad libitum. Data collection of digestible crude protein and digestible crude fiber was conducted by total collection method in metabolic cages for 7 days, while methane gas production measurement was conducted for 2 x 24 hours. The results showed differences in correlation values between the two types of treatments. Treatment with rice straw fermented with urea had correlation values of 0.937 for digestible crude protein and 0.507 for digestible crude fiber with coefficient of determination values of 87.9% for DCP and 25.7% for DCF. Meanwhile, in the treatment with rice straw fermented with urine, the correlation values were -0.632 for DCP and -0.991 for DCF with coefficient of determination values of 40.0% for DCP and 98.3% for DCF. The conclusion from this research is that the difference in correlation values is caused by the nitrogen source used for fermentation and the presence of accompanying compounds found in cattle urine used for rice straw fermentation.
