Most of protein content in feed was fermented in the rumen by bacteria system to produce amino acid and ammonia (NH₃). To avoid the bacterial fermentation of true protein, decreasing of protein dissolution and digestion in rumen is needed.

V-118, a maize single cross developed by Institute of Agricultural Science for Southern Vietnam. Performance of the cross has shown it’s promising stability yield. In intensive farming condition this cross could yield up to 10 tons  per hectare. On farmer fields, V-118 gave yield from 7 – 8 ton per hectare.

In this paper, specifications of 5 materials (including berberin from Coscinium fenestratum, curcumin from Curcuma longa and extracts of  Wedelia chinensis, Glycyrrhiza uralensis and Astragalus membranaceus) and 2 preparations under granulated forms were investigated and established.

One hundred and seven normal estrus buffaloes raising in small-houder farms (Nghe An province 40, Thanh Hoa 40 and Thai Nguyen 27) were allocated to one of three different treatment groups to find the efficacy of AI and optimum time of AI. The group A (n=29) received AI  at the time 12-18 h, group B (n=46) AI 18-24 h), group C (n= 32) AI 24-32h after the detection of heat signs

Easup district, DakLak province is nearly 14 thousand hectares of paddy land, accounting for more than 50% of short-term annual crops of the area. Although rice is the main crops, but characteristics of farming systems is an annual crop by cultivated rice on land dominate the area (75%).

Results of an assessment on 300 dairy cows (>75%HF) at dairy smallholder farms of Cu Chi and Hoc Mon districts, HCM City showed that there were 42.3% dairy cows having a long calving interval (more than 14 months); Supplied levels of ME/CP for individual cows were different because that body weight and milk yield were different but they were fed the same rations;

A total of seventy-two dairy male calves were randomly allocated into 9 groups, by which three levels of fresh milk replacement (70, 80 and 90% of fresh milk by milk replacer) and three periods of feeding fresh milk (1, 2 and 3 months) were applied

Five hundred fifty two fattening pigs from 2 farms in southeastern region had been allocated in the experiment during 2007-2009. Of which, 40 fatted pigs from terminal boars of three and four ways cross with F1 sow LY were slaughtered for meat quality evaluation

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);

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

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

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);

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).

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

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.

 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

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.
