Raising pigs on biological bedding

(Baonghean) - A new feature in livestock development in Do Luong is that some households have successfully applied pig farming technology on biological bedding, both minimizing environmental pollution and increasing economic efficiency.

Visiting Mr. Hoang Anh Tuan's pig farm in Xuan Son commune, Do Luong, Mr. Tuan said: Since 2003, the family has invested in raising over 30 sows, and by 2010, they built a farm and increased the number of pigs. The pig herd has increased, but they have to face environmental pollution even though the pigs are raised on cement floors, are washed with water every day, and have biogas treated... In 2013, when I learned that Hanoi University of Agriculture I had successfully researched the application of "raising pigs on biological bedding", reducing pollution in each school, I went to the school to learn the process. In 2013, my family invested in making biological bedding with an area of ​​900 m2 of barns, at a cost of 330,000 VND/m2.

Raising pigs on biological bedding at Mr. Hoang Anh Tuan's household in Xuan Son commune, Do Luong.

Mr. Tuan invested in building a barn floor divided into 2 parts: The part containing the bedding takes up 2/3 of the area of ​​the barn, with a depth of about 50 - 60 cm; the tiled or cemented part takes up 1/3 of the area. For each m2 of bedding, 1 m3 of sawdust and rice husks (including 2/3 sawdust and 1/3 rice husks) is needed to ensure non-toxicity and to be dried in the sun for 1 week before being used as bedding. Crushed corn: 1.8 kg/m2, probiotics: 0.1 kg/m2. After releasing the pigs into the barn, every day when the pigs defecate, the feces must be raked and spread evenly on the floor of the barn. If the bedding surface in the barn is dry, spray clean water evenly to ensure sufficient moisture. After 4 months, adding 10 grams of original yeast/m2 of the bedding surface of the barn floor will ensure it.

Piglets raised on litter are healthy, have shiny, clean fur, reduced antibiotic residues in their meat, are less susceptible to disease, and grow well. Instead of raising them on cement or brick floors, having to bathe and clean their manure every day, the model of raising pigs on litter floors saves labor, water, food costs, and veterinary medicine. The litter and probiotics work to decompose feces and urine excreted by livestock, limit foul and rotten gases; inhibit and destroy the growth of harmful microorganisms; keep livestock warm, and prevent diseases well. Biological litter can be replaced every 1.2-1.5 years; this is a source of quality fertilizer for crops. In the first disposal, at Mr. Tuan's barn, nearly 15 tons of manure were collected and sold to farms. With income to offset expenses, farmers will reduce the cost of investing in biological litter. Currently, Mr. Tuan's farm raises 150 sows, produces over 1,000 pigs, and has an annual revenue of over 1.5 billion VND.

Seeing the effectiveness of using biological bedding, in early 2014, Mr. Ho Si Du's family in Hamlet 15, Thuong Son Commune - Do Luong invested in applying and was supported by the Department of Science and Technology with probiotics, and guided on the process of building biological bedding with a scale of 250 m2. Mr. Du said: The total pig herd currently has over 150 sows, giving birth to over 1,500 pigs/year; although biological bedding has only been used to raise over 200 pigs, it has been initially very effective. In addition to reducing odor pollution, pigs raised on biological bedding are not affected by diseases so they grow very quickly. With an initial weight of 18 kg, after nearly 90 days of raising, the pig reaches an average weight of 85 kg/pig, with a selling price of 45,000 - 47,000 VND/kg, the family earns nearly 4 million VND/pig, after deducting expenses, the profit is more than 1 million VND/pig, higher than the traditional raising method of 400,000 - 450,000 VND/pig.

Mr. Tran Doan Hung, Head of the Department of Agriculture of Do Luong, said: Up to now, Do Luong district has had 6 farms applying pig farming on biological bedding in Van Son, Thuong Son, and Xuan Son communes. These models have opened up a direction for safe livestock development, especially for family farms and small-scale households located in residential areas. However, the investment cost for pig farming on biological bedding is still quite high, and it is in great need of State support in terms of loans and support for training and coaching on processes and techniques for households.
