REPLACEMENT OF SOYBEAN MEAL BY MORINGA OLEIFERA LEAF MEAL IN LUONG PHUONG LAYER PARENTS STOCK DIET

Abstract

This experiment is aimed to determine the replacement possibility of soybean meal by Moringa oleifera leaf meal based on crude protein (CP) content of soybean meal in the diet. The experiment was carried out on Luong Phuong parents stock in 16 weeks with a total of 360 Luong Phuong Parents stock layers and 48 cocks, equally allotted in 4 units (4 treatments). The crude protein content of soybean meal (P_KD) and crude protein content of Moringa oleifera leaf meal (P_BL) in the diet treatments (NT) as follows: NT1 100% P_KD + 0% P_BL, NT2: 70% P_KD + 30% P_BL, NT3: 60% P_KD + 40% P_BL, NT4: 50% P_KD + 50% P_BL. Birds in 4 treatments were fed with similar amount of feed with isocaloric and isoprotein contents. Results showed that the average laying percentage, egg productivity and fertile egg/hen during the experimental period of 4 treatments ranking from the highest to the lowest were NT2, NT3, NT1, NT4 respectively. The first grade hatch chicks/total incubation of 4 treatments ranked from the highest to the lowest as follows: NT4, NT3, NT2, NT1. The feed cost per each first grade hatch chick from the lowest to the highest was NT2, NT3, NT4, NT1 respectively. Based on the statistical analysis of the data, it was concluded that the replacement rate could be made up to 50% CP of soybean meal by that of Moringa oleifera leaf meal in Luong Phuong parents stock, however, the most efficient replacement rate was at 30 and 40%.
