In the case of pig losses, how to reduce losses? “Forage raising pigs can save 10%-30% of feed costsâ€. On April 15th, at the training session of Sihui, Professor Liu Yanfen of Guangdong Ocean University was a local farmer. Provide new ideas.
The pig is a single stomach, omnivorous, post-digestive tract fermented animal. The cecum and anterior colon are the main places for the pig to digest the green feed. Feeding the grass can accelerate the peristalsis of the large intestine, and some cockroaches stay in the large intestine for a longer period of time. Make food digestibility higher. "The new king grass, ryegrass, legumes, cowpeas, etc. of the leguminous family are all suitable pastures, and the latter can also improve the quality of the soil." Liu Yanfen said that different pastures, the harvest time and The parts that can be used vary widely, which requires the farm to be based on actual conditions.
Liu Yanfen said that when using pasture feeding, the grass can be chopped, beaten and fed with the concentrate, or the forage can be fed first, and then the concentrate can be fed. When feeding with boiled forage and feed, it is forbidden to cover the lid and boil. It should be ensured that the forage can be boiled to feed, avoid boiling at 40 °C-60 °C to avoid poisoning. In addition, the proportion of pigs fed grass at different stages is also very different. For sows, Liu Yanfen believes that the amount of pasture fed can reach 70%, while fattening pigs should be controlled below 30%.
A pig consumes about 350 kilograms of feed from birth to market. If it can save 10% of the feed, it will save more than 300 yuan. At present, most farms lose 50-150 yuan per pig. "Now the pasture can mature to replace some of the concentrate, and in this downturn, it can still make pigs profitable." Liu Yanfen said.
It is understood that as early as a few months ago, under the impetus of Siyan City's Xinran Pig Professional Cooperative, some farmers have been piloting pasture to raise pigs. "At present, I mainly use forage to raise sows, and the situation of constipation in sows has decreased." Wu Xiaobin, the head of Qingfeng pig farm in Shihui Town, Sihui, said that in addition, the low price of pigs is also the reason why he used forage to raise pigs. First, the pastures planted around his farm can grow up to one person in less than a month after harvesting, and “almost no cost†compared to feed.
At present, pasture raising pigs is concerned with its low cost of breeding, but at the same time it is equipped with larger planting land, and many farms do not have such resources. Liu Yanfen believes that different scales of forage can be planted in combination with the actual situation of the farm. “ farms can also be replaced as appropriate.â€
Barbed Wire
Galvanized barbed wire is perfect for livestock fencing, security fencing, and barriers. It is uniformly zinc coated, which makes it corrosion-resistant and durable to use. Besides, it is easy to install, and can be used directly or mounted on top of the other mesh fencing to provide additional security. The various specifications and designs can meet most commercial, industrial, agricultural, highway, and other applications.
