Abstract

The purpose of this study was to determine the effect of l-lysine supplementation in feed on the body weight gain, feed consumption, and feed efficiency of broilers. The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agriculture Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. This study used 80 day-old chicks (DOC) broilers. The method used is a Completely Randomized Design with four treatments and four replications. The treatments give were: T0 (control feed), T1 (control feed + 0.35% l-lysine), T2 (control feed + 0.70% l-lysine), T3 (control feed + 1.00% l -lysine). Data were processed using Variance Analysis, and Duncan test. The results of the statistical analysis showed that the supplementation of l-lysine in the feed had a significant effect on weight gain, feed consumption, and feed efficiency (P<0.05). It was concluded that supplementation of 0.70% l-lysine HCl in feed gave optimum results to weight gain, feed consumption, and feed efficiency of broilers.

Abstract

The purpose of this experiment was to know the effect of dl-methionine supplementation in feed on the body weight gain, feed consumption, and feed efficiency of broilers. The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agricultural Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. The experiment used 80 fourteen-day broilers. The method used in this research was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The treatments given were: T0 (control feed), T1 (T0 + 0.30% dl-methionine), T2 (T0 + 0.50% dl-methionine), and T3 (T0 + 0.70% dl-methionine). The variables observed were body weight gain, feed consumption, and feed efficiency. The results of the experiment showed that the treatment significantly affected the body weight gain, feed consumption, and feed efficiency of broilers (P<0.05). It was concluded that commercial feed supplemented with dl-methionine by 0.70% increased the growth performance of broilers.

Abstract

The study was conducted for 3 months from March to June 2013, using nine (9) male Bali cattle aged 2.5 - 3.5 years or average 3.0 years old based on dental estimates. The initial body weight range was 227-290 kg or an average of 257.40 ± 23.60 kg. Livestock was raising carried out in the Bero Sembada Farmers Group, Laen Manen District, Belu Regency, East Nusa Tenggara. The method used was an experimental method with treatments adjusted for habits of breeders in fattening cattle, which included feed management, housing, and health. The type of feed given during the study was Centrosema pubences, Clitoria ternatea, Fresh Zea mays straw, Pennisetum purpuphoides, Leucaena leucocephala, natural grass, Pennisetum purpureum and Sesbania grandiflora. The variables measured in this study include the color of the meat and fat. Measurement of the color of meat and fat using the standard color of meat and fat issued by the Indonesian National Standardization Agency (SNI: 3932: 2008, Regarding Quality Standards for Carcass and Meat of Beef Cattle). The data collected were analyzed using descriptive statistical procedures. The results of the study showed that male Bali cattle fattened with forage produced a meat color score average of 9.00 or dark red color, while the average fat color score produced was 5.33 or yellowish-white color. It can be concluded that the characteristic color of meat from male Bali cattle fattened with forage on smallholder farms is dark red, while the color of fat is yellowish-white.

Abstract

The study were aimed to determine the lignin degradation in fermentation of cocoa pod with Pleurotus ostreatus. The research methods was using three treatments and four replications. T0 = fermentation of cocoa pod in 10 days, T1 = fermentation of cocoa pod in 15 days, and T2 = fermentation of cocoa pod in 20 days. The mixture was put into a container aerobically. The variables observed were dry matter (DM), crude protein (CP), crude fiber (CF), crude fat (CFt), ash and lignin content. This study was designed using the completely randomized research design with a unidirectional pattern analysis of variance (oneway ANOVA). Significant variables went through Duncan's Multiple Range Test (DMRT). The result showed that the lower lignin content was T2 = fermentation of cocoa pod in 20 days = 6.40 ± 0.12%. It could be concluded that the addition of fungus Pleurotus ostreatus on cocoa pod fermented during 20 days was the lower lignin content in fermentation of cocoa pod.

Abstract

Energy is a crucial problem because it is inversely proportional to the rapid population growth. As a result, energy reserves are running low, especially fossil energy. For this reason, innovation is needed to provide alternative fuels to address household energy needs. One alternative fuel to overcome household energy needs. Briquette can be used as an alternative fuel which is expected to be able to overcome the energy crisis because it comes from materials that are around. Utilization of livestock and agricultural waste is one alternative that is very appropriate to overcome rising prices and oil fuel shortages. Utilization of waste and use of renewable energy needs to be integrated. In this study aims to utilize waste into renewable energy. The method used in this study was a completely randomized design (CRD) with 4 treatments and which were repeated 4; R1:80% cows manure charcoal + 15% Rice husk charcoal + 5% Starch flour, with treatment R2: 70% Cows manure charcoal + 25% Rice husk charcoal + 5% Starch flour; R3: 60% Cows manure charcoal + 35% Rice husk charcoal + 5% Starch flour; R4: 50% Cows manure charcoal + 45% Rice husk charcoal + 5% Starch flour. The composition of the four briquettes has the same density (100g) with a pressure of 30 kg/cm2. The variables studies observed were water content, ash content, combustion rate and heating value. The data obtained were processed using variance according o the Completely Randomized Design (CDR) and Duncan's multiple range test. The results showed that the use of cows manure charcoal and rice husk with different levels had a significant effect (P<0.05) on the variables studied. It was concluded that the use of 50% cows manure charcoal, 45% rice husk charcoal, and 5% starch produced the best quality briquettes with a moisture content of 3.11%, ash content of 23.72%, burning rate of 0.26 g/sec and heating value 1247 cal/g.
