Supplementation of Biopeptide from Chicken Feet to the Immune System and Growth of Broiler Chicken
Full text linkThe safety of poultry products, especially broiler chickens, can be stated to be relatively low. Antibiotic growth promoter (AGP) is used to improve chicken performance and maintain immunity. The ban on the use of AGP triggers the innovation of other materials to replace the function of AGP. Biopeptide is a solution that can be used. Biopeptides can be made from materials with a high protein content, for example, waste from chicken slaughterhouses. The waste that can be used is chicken feet, biopeptides produced from hydrolytic proteins have antioxidant and antimicrobial properties. These properties can improve the performance and immune system of broiler chickens. The aim of the study was to examine the supplementation of biopeptides from chicken feet on the immune system (total Escherichia coli and internal organ) and the growth of broiler chickens. The research material was 200 day old chickens of broiler strain cobb unsex, which were reared for 42 days of the rearing period. The treatment feeds were P0: basal feed, P1 basal feed + 2% biopeptide, P2: basal feed + 4% biopeptide, P3: basal feed + 6% biopeptide. The collected data were analyzed using analysis of variance with the Tukey test (BNJ). The results showed that biopeptide supplementation from chicken feet had a significant (P0.05) on liver weight and Avian Influenza antibody titers for broiler chickens. Biopeptide supplementation from chicken feet can reduce total Escherichia coli, and spleen weight, and increase the bursa of Fabricius weight, body weight gain, and feed efficiency for broiler chickens. Biopeptide supplementation from chicken feet of 6% gave the best results in body weight gain and feed efficiency
Utilization of Different Concentration Sugarcane Molasses to the Quality of Goat Feces-Chicken Excreta-Coconut Husk Organic Liquid Fertilizer
Full text linkIndonesia is an agricultural country that certainly has the potential for agricultural waste and by-products. Some of those in Indonesia are livestock manure, coconut husk, and sugarcane molasses. Utilization of this waste is limited, which is causing various environmental problems such as environmental pollution. The study is aimed to determine the quality of organic liquid fertilizer made by raw material from goat feces-chicken excreta-coconut husk with various sugarcane molasses concentrations (P0= 0%; P1= 5%; P3= 15%; P4= 20%; P5= 25%). The fermentation was carried out anaerobically for 21 days. The parameters of temperature, pH, organoleptic (color and odor), levels of C-organic, nitrogen (N) total, phosphorus (P) total, potassium (K) total, and biological tests were observed. Biological tests were conducted in the growth of mung bean (Vigna radiata) and spinach (Amaranthus tricolor). Data were analyzed using one-way ANOVA. Variations in the addition of molasses sugarcane did not affect the liquid fertilizer's temperature and pH during fermentation. However, the treatments had positive effect on organoleptic test, C-organic, N total, P total, K total, and biological tests. The addition of 15% sugarcane molasses (P3) showed a dominating performance toward most of the parameters tested. The P3 treatment produced liquid fertilizer with a pleasant smell, and the contents of C-organic, total N, total P, and total K were 2.12%, 0.25%, 0.13%, and 0.13%, respectively. and produce spinach as a biological test with plant height, number of leaves, leaf width, stem diameter, and root length were 21.82 cm, 6.66 sheets, 3.59 cm, 4.09 mm, and 14.67 cm, respectively

Factors Affecting Buffaloes’ Farmers Commitment toward Accessibility of Resources in Pemalang District, Central Java, Indonesia
Full text linkThis study was aimed to measure the farmers' commitment, accessibility of resources (information, capital, and assistance), and the correlation between those variables. The research method used in the current study was the survey method. The location was purposively selected in Pemalang Regency, the regency with the largest buffalo population in Central Java Province. Three subdistricts (20%) with formal and informal farmers' groups were selected, and there were Taman, Pemalang, and Belik subdistricts. One Village was selected for each subdistrict. Respondents for informal groups were taken by census method. Respondents in formal groups were taken by random sampling, and the number of respondents followed the number of informal groups. There were 136 farmers selected as respondents. (69 from each formal and informal groups). The data were analyzed using the descriptive and rank Spearman correlation methods. The results showed that the farmers' commitment of formal group and informal group members was in the moderate and low categories respectively based on the percentage score interval scaling method. Resources accessibility of formal and informal members of the farmers' group was in the low to moderate category, but the member of formal groups was slightly better. There was a strong correlation between the accessibility of resources with the commitment in the formal groups, whereas in the informal groups there was a moderate to strong correlation between the accessibility of resources with the commitment of buffalo farmers. Based on the conclusion, this study recommend that the government should assist the informal farmer group to establish formal group with the result that would increase farmers accessibility toward information, support, and capital. That condition would increase farmers commitment to continue their buffalo farm business in Pemalang Regency
