240 mixed male and female crossbred (Super M x Nong nghiep breed) ducklings at 21 days of age were allocated at random to three treatments, with four replicates on one farm. Each replicate group, consisting of 20 ducks was managed in a separate pen.

 In ethnic minority areas of Binh Phuoc and Dak Nong provinces, rice growers have been rearly approached to new techniques of rice production, therefore leading to their rice yields were low and high cost price in comparing to other regions

The aim of this study is to investigate the effects of body-weight at 22^nd week of age on the reproduction of laying hens Luong Phuong in the practical conditions of South Vietnam. Total of 1,800 pullets at 6^th week of age were used for three treatments of controlling body-weight.

2-acetyl-1-pyrroline, one of the most useful applications of molecular markers in rice breeding, is the marker-assisted backcrossing (MAB) approach to rapidly and efficiently transfer a gene into a variety that is popular with farmers. In this approach the desirable features of the recurrent parent are retained by selecting against background markers of the donor parent

Black sesame variety with good characteristics: high good seed ratio, drought resistance, vigorous branches, is mainly cultivated in Long An province. The main cropping season is Spring-Summer. This crop is often grown on upland, poor soil and limited water availability. Some technical solutions of this study including quantity of phosphorous and potassium fertilizers

450 laying duck at 29 week old (Cò breed) were collected and randomized in to 3 treatments, 3 pens /treatment, 50 head /pen such as: T1: control diet base on soybean meal as protein source (KPĐC); T2 and T3: to replace 30% and 60% soybean meal with Tra fish by products (PP30 and PP60).

750 twenty one day ducks (Super M x Nong nghiep breed) were collected and randomized in to 5 treatments, 3 pens /treatment, 50 head /pen such as: T1: control diet base on soybean meal as protein source (KPĐC); T2 and T3: to replace 30% and 60% soybean meal with Tra fish by products (PP30 and PP60);

The in sacco experiment was conducted on 2 Red Sindhi cows installed T-cannula to evaluate degradability potential of dry matter and crude protein of soybean meal and peanut cake treated at different temperature and time in the rumen.

The current study was conducted on private farms of Binh Phuoc, Nghe An, Thanh Hoa and Thai Nguyen provinces, with 120 landrace buffalo cows. These animals were raised under extensive production system. The buffalo cows were randomly allocated into three groups

In pig breeding programs, boars and gilts ranked best as purebreds are not necessarily breeding the best crosbreds. Hence, the aim of this study is to estimate the genetic correlations between purebreds (Yorkshire and Landrace) and crossbreds (reciprocal Y x L);
