Bài viết Sự biến động về ưu thế lai của các tổ hợp lai khác nhau giữa 3 giống lợn Duroc, Piétrain, Landrace phân tích sự biến động của ưu thế lai về một số tính trạng sản xuất của các tổ hợp lai giữa 3 giống lợn Duroc, Piétrain, Landrace để chọn ra các tổ hợp lai tốt nhất đưa vào sản xuất. | TNU Journal of Science and Technology 227 14 42 - 47 VARIABLE IN HYBRID SUPERIORITY OF THE DIFFERENT HYBRID COMBINATIONS BETWEEN DUROC PIÉTRAIN LANDRACE Nguyen Van Binh Dinh Ngoc Bach TNU - College of Economics and Techniques ARTICLE INFO ABSTRACT Received 26 6 2022 Studying the factors affecting the production capacity of breeding stock is very important to propose solutions to improve their production. The purpose Revised 22 8 2022 of this study is to analyze the variation of hybrid superiority in some Published 23 8 2022 production traits of the hybrid combinations between 3 breeds of pigs Duroc Piétrain Landrace in order to select the best hybrid into KEYWORDS production. The study was carried out on 767 individuals of 3 breeds Duroc Piétrain Landrace and 528 individuals of 04 hybrid combinations between Hybrid superiority them with different hybrid formulas. The studied traits were Weight gain Weight gain back fat thickness feed consumption lean percentage. The research results show that The best hybrid advantage is in the F1-forward hybrid between Back fat thickening Duroc x Piétrain Duroc x Landrace and Piétrain x Landrace pairs for all 4 Feed consumption traits. In particular the hybrid advantage in terms of weight gain was highest Lean percentage in the Duroc x Piétrain hybrid the lowest in the Piétrain x Landrace hybrid But the hybrid advantage in lean percentage was highest in Piétrain x Landrace hybrid and lowest in Duroc x Piétrain hybrid . The traits of weight gain and lean percentage have hybrid advantage gt 0 whereas the traits of thick back fat and feed consumption have hybrid dominance lt 0. This is an important advantage in crossbreeding to create pigs with good growth high lean percentage but low feed consumption.
