Abstract

: Glutamate is an alternative feed additive that is safe and environmentally friendly in improving the quality of broiler chicken carcass. This study aims to determine the effect of glutamate produced by Lactobacilus plantarum MV on the quality of broiler chicken carcass. The aim of this research was to get the optimum doses of glutamate in feed broiler for increasing the quality of carcass. The design used was a Completely Randomized Design (CRD), with 6 treatments and 4 replications. This study used 240 broiler chicken strain MB 202 from PT Charoen Phokphand Indonesia, 1 day old and the treatment started at 7 days of age with 5 weeks of treatment. Each experimental unit consisted of 10 chickens. The Glutamate doses in groups were, A (0.4% commercial glutamate; B (0% glutamate); C (0.2% glutamate); D (0.4% glutamate); E (0.6% glutamate); F (0.8% glutamate). The results indicated that glutamate up to 0.8% had significant effects on carcass quality, consisting of reducing abdominal fat (0,64%) and cholesterol (0,64%), as well as increasing meat protein (73,09%) and cooking losses (26.69%). It can be concluded that 0,8% glutamate in broiler feed was increasing the quality of carcass.

Abstract

The performance of laying hens is affected by feed quality and can be seen from feed consumption, egg weight and hen day production (HDP). The aim of this study was to determine the quality of feed on the performance of laying hens. Sampling was carried out via interview on farmers in East Lombok representing each sub-district with a minimum population of 500 laying hens. Sampling of feed ingredients and 20 eggs was carried out on each farm for analysis in the laboratory. The descriptive analysis was performed on acquired data. The results showed that farmers in East Lombok used different percentages of corn, concentrate and mineral feed ingredients. The nutritional content of feed given consist of crude protein (14,17-16,90%), crude fat (3,17-3,36%), crude fiber (6,13-7,06%), calcium (1, 03-1,29), phosphorus (0,26-1,33%) and metabolic energy (2751,96-2925,79 Kcal/kg). The conclusion is some farmers in East Lombok Regency provide feed that does not suitable to the nutritional needs required by laying hens, namely the content of crude protein, calcium and phosphorus according to SNI standards which has an impact on reducing egg weight and HDP.

Abstract

The high price of protein feed for livestock makes maggots potential as an alternative protein feed. The first stage in this research was maggot maintenance and maggot harvesting on the 15th day of maintenance. Next, measurements of the physical and chemical quality of fresh maggot were carried out. Parameters for measuring the physical quality of fresh maggot consist of harvest weight, individual weight, individual length and color. The parameters for measuring the chemical quality of fresh maggot consist of water content, ash, crude fat, crude fiber and crude protein. Data analysis was carried out using the Independent Sample T-test. The results showed that the maggot that was cultivated with the special media used had an average harvest weight of 1.24 kg, while the maggot that was cultivated without the special media used had an average harvest weight of 0.72 kg. The maggot that was cultivated with the special treatment of the media used contained 31.5% protein, while the maggot that was cultivated without the special treatment of the media used contained 32.9% protein. The conclusion of this study is that maggot that is cultivated with the special treatment of the media used produces maggot with superior physical quality compared to maggot that is cultivated without the special treatment of the media used.

Abstract

The mold Aspergillus flavus produces a metabolite molecule called aflatoxin. Aflatoxin chemicals can have harmful effects on both humans and livestock when they are present in feed ingredients. Aspergillus flavus frequently grows on corn, one of the feed ingredients. Examining the amount of aflatoxin contamination in corn in North Lombok Regency and how it affects laying hen performance was the goal of this study. Random sampling was done from each subdistrict, and descriptive analysis was done on the collected data. According to the study's findings, aflatoxin compounds, which have a range of 87.99–132.38, were found in 50% of corn. Aflatoxin concentration in feed surpasses the 60 ppm SNI guideline by 33.33%.  Performance is impacted by aflatoxin compounds in maize; specifically, 50% of feed intake, 50% of egg weight, and 100% of noncompliance with SNI and corporate criteria are not met. The results of this study suggest that aflatoxin levels in diet have an impact on laying hens' declining performance.
