The Effect of Debeaking and Crude Fibre in Ration On Canibalism and Performance of Muscovy Duck

A research has been conducted from September 3rd until November 2nd 2002 to study cannibalism and performance of Muscovy duck. The method applied was experiment with factorial pattern of Completely Randomized Design (CRD). The first factors were debeaking (P) : p1 = control, p2 = debeaking. The second factors were crude fibre content in ration (R) : r1= 6 %, r2 = 8 % and r3 = 10 %.  Parameters observed were cannibalism mortality, food consumption, growth rate, carcass production, meat and blood cholesterol and meat fat. The duck used were 96 heads at one week old and cage in 24 pens with litter floor.  The results indicated that debeaking had no significant effect on food consumption, growth rate, carcass percentage and blood cholesterol, but it had significant effect on carcass weight and meat fat up to 8 weeks old. Crude fibre had significant effect on blood and meat cholesterol. (Animal Production 6(1): 9-16 (2004) Key Words: Debeaking, Crude fibre, Canibalism, Production Performance

Carcass Evaluation of Crossbred Betweeen Cockerel Kampung Chicken and Layer Hen

The research was conducted to the characteristics of carcass evaluate crossbred between cockerel of kampung chicken and Lohman layer hen. Sixteen crossbred chickens and 16 kampung chickens were reared under a similar management from 2 - 12 weeks old. The chickens were given a commercial feed which contains 21% crude protein at 2 - 4 week old, and 14% crude protein and metabolizable energy 2800 kcal/kg at 4 - 12 weeks old. The data of carcass weight, rear back weight, fore back weight, breast weight, and thigh weight were collected. Meat and bone on breast and thigh were separated. The results showed that with under similar management and feeding, the carcass values of crossbred chicken were not significantly different with kampung chicken. The crossbred chickens have meat production rate of 2.83 times as compared to kampung chicken. Higher crude protein than 14% with a balance metabolizable energy will increase the quantity and quality of crossbred chicken carcass.

Optimization on Fermentation Process of Protein Concentrate of Jatropha Seed Cake with N Sources and Minerals Supplementation

The objective of this research is to produce alternative food sources of protein by optimizing the potential of jatropha curcas which is agroindustry waste. This study is planned in two years and is a series of jatropha seed exploration through fermentation using Lactobacillus acidophilus. Specific targets in the first year of study were to assess the optimization of the fermentation process by supplementing the source of N soybean meal and fish meal. Experiments using Completely Randomized Design (RAL) factorial pattern with first factor was supplementation (F) and second factor was incubation time (W), fermentation optimization consisted of: F1 (F0 + 2.5% soybean meal flour), F2 (F0 + 2.5% fish meal), F3 (F1 + 0.45% Dicalsium Phosphat) and F4 (F2 + 0.45% Dicalsium Phosphat). The incubation time is differentiated W1: 3 days, W2: 5 days and W3: 7 days. It can be concluded that: dry matter, gross energy, calcium and phospor are influenced by interaction between type of supplementation of source of N + DCP with fermentation time, whereas fat content is only influenced by fermentation time with optimal time decrease of fat content is 5,92 days. Total protein and amino acid levels are only influenced by different types of supplementation. Phorbolester antinutrition levels are influenced by the duration of the fermentation.  Based on antinutritive as a limiting factor. F4W5 is the best treatment and can used as a feed ingredient.
