Abstract
Tannery waste contained 90.93% DM, 77.02% CP, 0.77% CF, 2.83% EE, 7.19% ash and 3,450 kcal ME/kg DM. A total of 144 day-old broiler chicks were divided into three dietary groups; D1 (Containing 10% protein concentrate-PC), D2 (Containing 5% PC+5% tannery waste-TW) and D3 (Containing 10% TW) having 3 replicates of 16 chicks in each. The birds were fed broiler starter diet containing 22% CP, 3,000 kcal ME/kg and broiler finisher diet containing 21% CP, 3,100 kcal ME/kg up to 42 days of age, and meat yield traits were measured from the representative birds from each replication to asses the feasibility of using tannery waste in the diet of broiler. Feed intake, live weight, feed conversion efficiency and livability did not differ between diets (p>0.05) but the cost of production and profitability differed significantly (p<0.001). Profitability of D1, D2, and D3 diets were 2.98, 9.90 and 14.04 Taka/kg respectively. Diets did not affect on meat yield traits (p>0.05), except gizzard, shank and feather weight (p<0.01). Gizzard and shank weigh were improved with increasing level of tannery wastes in the diet, hence tannery waste can be used without any harmful effect in the broiler diet.
