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);

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

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

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;

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%).

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

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.

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
