Thay thế khô dầu đậu tương bằng bột lá Moringa oleifera trong khẩu phần của gà đẻ bố mẹ lương phượng

Bài viết nhằm mục đích xác định khả năng thay thế khô dầu đậu tương bằng bột lá Moringa oleifera tính theo tỷ lệ protein thô (CP) của khô dầu đậu tương có trong khẩu phần. Thí nghiệm được thực hiện trên gà đẻ bố mẹ giống Lương Phượng trong 16 tuần với tổng số 360 gà mái và 48 gà trống, chia đều thành 4 lô (4 nghiệm thức). | TNU Journal of Science and Technology 226 01 99 - 105 REPLACEMENT OF SOYBEAN MEAL BY MORINGA OLEIFERA LEAF MEAL IN LUONG PHUONG LAYER PARENTS STOCK DIET Hoang Thi Hong Nhung1 Tu Quang Hien2 Tu Trung Kien2 Tran Thi Bich Ngoc3 1Hung Vuong University Phu Tho 2TNU University of Agriculture and Forestry 3National Institute of Animal Science ARTICLE INFO ABSTRACT Received 05 01 2021 This experiment is aimed to determine the replacement possibility of soybean meal by Moringa oleifera leaf meal based on crude protein CP Revised 20 01 2021 content of soybean meal in the diet. The experiment was carried out on Published 31 01 2021 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 KEYWORDS treatments . The crude protein content of soybean meal P KD and crude protein content of Moringa oleifera leaf meal PBL in the diet treatments Replacement NT as follows NT1 100 PKD 0 PBL NT2 70 PKD 30 PBL Soybean meal 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 Leaf meal isoprotein contents. Results showed that the average laying percentage M. oleifera egg productivity and fertile egg hen during the experimental period of 4 Layer parents stock 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 .
