Abstract
Hundred day old chicks Arbor Acres CP-707 were used randomizedly in this experiment, to study the effects of various levels skipjack tuna bone meal in ration on broiler carcass tenderness and abdominal fat, and were studied for six weeks. Research using Completely Randomized Design (CRD). The dietary treatments are: R0 basal diet as control, R1 basal diet + 2% tuna bone meal, R2 basal diet + 4% tuna bone meal and R3 basal diet + 6% tuna bone meal, and each treatments were repeated five times. Results indicated that the highest carcass tenderness was get from the broiler that fed basal diet with 6% tuna bone meal (125,4 mm/g/10sec) and the lowest was get from the broiler that fed basal diet (107 mm/g/10sec). For the abdominal fat, the results is broiler that adding skipjack tuna bone meal in the ration will give more abdominal fat to the broiler (1.89% - 1.92%) versus 1.85% for basal diet.
Highlights
In formulating diets, it is essential to know the birds nutrient needs, and the concentration of these nutrients in the various ingredients
The highest carcass tenderness was get from the broiler that fed basal diet with 6% tuna bone meal (125,4 mm/g/10sec) and the lowest was get from the broiler that fed basal diet (107 mm/g/10sec)
The highest abdominal fat is from R3 (1.92) that using 6% skipjack tuna bone meal and the lowest is from R0 (1.85) the basal diet without skipjack tuna bone meal
Summary
In formulating diets, it is essential to know the birds nutrient needs, and the concentration of these nutrients in the various ingredients. Indicated that skipjack tuna gill meal in ration has no significantly effect on broiler carcass, but it can replace the function of fish meal in the ration. The most important factors are genetics, age of the animal, location of the cut on the carcass, processing, method of cooking and degree of doneness (Epley, 2011). According to Widjastuti et al (2011), until 6% tuna fish silage in the diet, have no significant effects, but the 4% tuna fish silage, has the best results on final body weight, carcass persentage and meat protein conversion on broiler. The cholesterol contents of the carcass and liver were significantly lower in Lactobacillus cultures fed broilers, but not the muscle. Supplementation of Lactobacillus culture in the broiler diets, significantly lower in fat contents of the liver, muscle and carcass (Kalavathy et al, 2006). Most poultry rations incorporate some fish meal at levels of about 2-5% of the ration; and according to Lengkey, et al (2011), for mash ration supplemented with skipjack tuna gill meal (1.89%) and crumble ration supplemented with skipjack tuna gill meal (2.08%)
