Efek Penambahan Belimbing Wuluh (Averrhoa Bilimbi L.) dalam Ransum terhadap Performan, Karkas dan Income Over Feed Cost Ayam Kampung

Starfruit (Averrhoa bilimbi L.) can serve as an acidifier which can improve digestive enzymes work, suppress the growth of pathogenic microbes, protecting feed from microbial and fungal attack and to improve the palatability of feed. The main objective of this study was to determine the effect of starfruit in the ration on the performance (feed intake, body weight gain, feed conversion), the weight of carcass parts, fatty meats, and income over feed cost. The study used 80 chicks two weeks old village with a complete randomized block design experiment method. The treatment consisted of control diet (P0), and three levels of addition of starfruit (P1 = 0.5%; P2 = 1%; and P3 = 1.5%). Each treatment was repeated 5 times. Rations and water were given adlibitum. The trial period lasts for 30 days. Test performed to determine differences in Duncan.The results showed the addition of up to 5% starfruit into the ration does not affect the performance of chicken and chicken carcass weight parts. The highest value of income over feed cost was achieved by treatment with the addition of 0.5% ration starfruit juice

Energy-Protein-Consentrate as Product of Glucosamine Extract from Shrimp Waste on Performance Ofnative Chicken

Material shrimp waste contains a lot of liquid extract dissolved nutrients, especially protein primary metabolite degraded, the process of protein back into a higher structure in the form of glucosamine will have a biological value as a source of energy-protein concentrate. Chitin Extraction of shrimp waste was done microbiologically using Bacillus licheniformis and Lactobacillus sp. Ration is a major determinant in the maintenance of super chicken intensive system, as the provision of energy and protein for growth. This research was aim to feeding trial of EPC product (energy-protein concentrates) on ration chick nature through performance measured (consume of ration, weight gain, and feed efficiency), and choice level of EPC product on ration through measure carcass production (weight of carcass). The trial used Completely Randomized Design (CRD). Statistic data analyzed was used variants, followed by Duncan Multiple Range Test. The result indicated that: 1. The use of energy-protein concentrates (EPC) in anative chickenration feed consumption resulted in the same response. 2. The use of energy-protein concentrates (EPC)in a chicken feed at a rate of3% can increase weight gain, live weight and carcass weight, and efficiency offeed utilization. 3. Rations containing 18.5% crude protein and metabolizable energy 2,800 kcal / kg which iscoupled with the EPC3% yield performance of the supernative chicken which is equivalent to the standard diet (20.5% crude protein and metabolizable energy of 3,000 kcal / kg)

Age Maturity of Female Japanese Quails Fed Diets Containing Katuk Leave Meal (Sauropus androgynus L.Merr.

This experiment was conducted to study the effects of katuk leave meal on sexual maturity in Japanese quail. Three hundred female Japanese quails, with 4 weeks age, were assigned into a completely randomized design with 4 treatments i.e., R1 (diet with neither katuk leave meal nor cholesterin), R2 (diet without katuk leave meal + 0.10% cholesterin), R3 (diet with 15% katuk leave meal without cholesterin), and R4 (diet with 15% katuk leave meal + 0.10% cholesterin). The parameters measured were estradiol hormone in plasma, and age maturity (five percent henday production). Estradiol hormone was measured with Radioimmunoassay. The data were collected and analyzed by using completely randomized design. The results showed that the addition of 15% katuk leave meal in the diet significantly decreased the estrogen concentration (P<0.05), so that slow down on the age maturity of female Japanese quail.
