Pig production is an expert of farmers in Thua Thien Hue and Quang Nam, more than 80% of sows, are kept in small farm holdings. To meet increasing demand for pig husbandry systems for pigs, smaller owners have enhanced breeding and feeding systems, while others tried to continue to produce larger pigs poorly designed facilities. Intensive farming has increased, so has disease problems, especially in the period before and after weaning, therefore, not surprising that the intestinal disease caused considerable losses in the period , but also housing base system is very poor and not suitable for young sows and. | Influence of different breeds feeding and housing systems on sow reproductive performance and piglet s resistance to diseases in Central Vietnam Nguyen Quang Linh1 Hoang Nghia Duyet1 Ngo Huu Toan1 Vu Van Hai1 Ha Thi Hue1 Colin Cargill2 1 Hue University of Agriculture and Forestry Vietnam 2 South Instutute of Livestock Development Australia 1. INTRODUCTION Pig husbandry is a professional of farmers in Thua Thien Hue and Quang Nam more than 80 of sow population which are kept in small holding farms. In response to the increased demand for piglets for pig production systems more small holders have intensified their breeding and feeding systems while others have attempted to continue to produce pigs in older poorly designed facilities. As intensification has increased so too have disease problems particularly in the pre and post-weaning stages so there are not only surprising that enteric diseases cause very substantial losses in this stages but also housing system is very poor facilities and not suitable for sows and young piglets as farrowing crates and piglet areas pregnancy sow area and also heating section as well. While the diseases and other components involved can usually be controlled by a combination of good management and strategic vaccination the sub-optimal environment provided on many farms is also a major risk factor especially in the farrowing and weaning areas. Antibiotics which add significantly to the cost of production are used to overcome these deficiencies and their indiscriminate use is probably contributing to the current high level of multi-drug resistance in isolates from pigs in Vietnam. This may also have serious human health implications. The better understanding of risk factors that are contributing to pig health problems and limiting or reducing production it is proposed to survey a large number of small holder farms in Quang Nam and Thua Thien Hue provinces.
