THE EFFECTS OF DIFFERENT LEVELS OF LOCUST (Locusta migratoria)MEAL ON THE GROOWTH PERFORMANCE OF COBB BROILERS

A study on the effects of different levels of Locust meal added to the ration to determine the feed consumption, live weight gain, feed conversion efficiency, mortality rate, and income over feed and chick costs of Cobb broilers on May to July 2017 at Mindanao State University Fatima, General Santos City. The study was laid out in a Complete Randomized Design (CRD) having four treatments and each treatment was replicated three times. The treatments were(T1), pure commercial ration, (T2), 2.5% LM, (T3), 5% LM and (T4), 7.5% LM with four birds per replication. Birds was fed with 0, 2.5 and 5% LM consumed the same (2.95 kg) amount of feed while those birds fed with 7.5% LM in the ration consumed 3.26 kg. The highest （1.05kg) live weight was obtained from birds with 2.5% LM while the lowest (0.94kg) was from the birds with 7.5%LM in the ration. Birds fed with 0 and 5 % both gained live weight of 1.03 kg. The bird fed with 2.5 %LM required 2.82 unit of feed to obtain a unit live weight. Birds fed with 5 and 0% LM required 2.86 and 2.87 respectively while birds given 7.5 %LM required 3.37. A mortality rate of 2.08% was observed in birds with 7.5% LM. The highest (Php 8.33) incomes were from birds fed with 2.5% LM while the lowest （Php -11.27) income was from birds fed with 7.5%LM in the ration. Statistical analysis shows no significant difference among treatment means in all parameters.
