Influence of Boiled Cassia Tora Seed Meal on Carcass and Internal Organs Characteristics of Starter Broiler Chickens

Abstract

An experiment was conducted to evaluate the effect of 30 minutes boiled Cassia tora seed meal in starter broiler chicken diets on carcass and internal organs characteristics, using one hundred and twenty day-old Hubbard broiler chicks. Five starter broiler chicken diets were formulated such that 30 minutes of boiled Cassia tora seed meal were included at 0%, 5%, 10%, 15% and 20% designated as treatments T1, T2, T3, T4 and T5 respectively. The chicks were randomly divided into five groups of twenty-four (24) chicks each and allocated to the five dietary treatments replicated three times with 8 birds per replicate in a Completely Randomized Design (CRD). The parameters measured were live weight; dressed weight, carcass weight and internal organs weights. Feed and water were given ad libitum throughout the 28 days of the research period. The results showed that all the carcass characteristics parameters measured were not significantly different (P>0.05) across treatment means except for wings which had values ranging from 10.32kg for T 1 to 8.93kg for T2. Live weights were 1165.00kg, 1298.67kg, 1206.60kg, 1158.67kg and 1006.33 kg for birds fed diets T1, T2, T3, T4 and T5. The dressed weights were 1084.67kg, 1194.67kg, 1108.00kg, 1078.00g and 936.00kg for birds fed T1, T2, T3, T4 and T5 diets. The values obtained from the dressing percentage were 93.13%, 91.90%, 91.70%, 93.06% and 92.96% for birds fed T1, T2, T3, T4 and T5 respectively. The result of breast weight numerically showed that birds fed T5 diet had the least value of 21.35kg while birds fed T2 had the highest value 24.57kg.Thigh weight showed that birds fed T5 diet recorded 11.05kgas the lowest value and T2which was 12.24kg as the highest value. Drumstick evaluation showed birds fed T5 as the poorest performed and T4 as the best performed and the back cut values showed T1 as the poorest performed with a weight of 14.12kg and T4 as the best performed with the weight of 15.55kg. Small intestine, large intestine, proventriculus and pancreas had significant differences (P<0.05) among the treatments while supplementing 30 minutes of boiled CTSM in broiler feed at 5% to 20 % inclusion levels had no significant difference (P>0.05):on the heart, liver, kidney, lungs, spleen, empty gizzard and gall bladder across the respective treatments. It was concluded from the results obtained that 30 minutes of boiled Cassia tora seed meal (BCTSM) could be included up to 20% in broiler starter chicken diets without any adverse effects on the carcass and internal organs characteristics.
