With the arrival of the era of meager animal husbandry, the simple breeding of a kind of livestock and poultry often fails to achieve good results due to various factors such as the market and cost. The new technology of efficient rearing of pigs and chickens is a practical technology that is particularly suitable for rural farmers. It is introduced as follows:
First, the cycle of procedures
1. Fermentation of chicken manure with lactic acid method
There are many methods for feeding pigs with chicken droppings, such as drying, fresh feeding, and conventional fermentation, but it is best to use lactic acid to ferment chicken droppings. Because the use of this method can make chicken manure into a high quality, good palatability pig feed. The fermentation method is to first dry the chicken manure to 70% dry, and then mix proper amount of lactic acid bacteria and 10 kilograms of wheat bran or rice bran into each 100 kg of chicken manure and put it into a nontoxic plastic bag and other containers for sealed fermentation for about 10 days. You can smell the wine. The proportion of incorporation in the feed should not exceed 40% when feeding pigs, and not more than 20% in sows, especially pregnant sows.
2. Use chicken manure fermentation bred chicken
Daily fresh pig manure will be collected and piled, about 500 kilograms each, spread out and dried till 70% dry, and then add 20% of soil, 3% of bran or rice bran, and mix well with plastic film to seal the manure. 7 days or so. Dig a 50 cm deep, wide and free pit on the flat ground, then spread the well-fermented pig manure in the pit about 30-40 cm thick. Cover it with grass, straw or sacks and keep it moist. Prevent it from raining. water. Generally about 20 days can give birth to crickets, insects and maggots. The worms produced by the feces produced by a pig can generally feed about 20 chickens.
3. Fermenting Chicken Manure with Vitality 99 Fermenting Agent
400 kg of chicken manure (about 120 kg into dry material), add 25 kg of corn flour, stir well to make the corn powder hygroscopic, and add 10 kg of reconstituted filler (loose agent). One pack (125g) of bio-fermentation agent is melted, sprinkled into the material, and mixed evenly. Then the material is tightly sealed with a plastic cloth or bag, and anaerobic fermentation is carried out. When feeding pigs, the maximum amount must not exceed 30% of the feed formulation for pigs, that is, the highest can only replace 30% of the compound feed.
Second, the matters needing attention
1. Do a good job of fermentation environment management
Due to contamination of the surrounding ground and odor during the process of manure fermentation, a large number of mosquitoes and flies will be breeding in summer and autumn. Therefore, the treatment site must be far away from the living area and keep a certain distance from the farm, especially away from life. Produce water sources and prevent the destruction of rats and wild animals, minimizing the pollution to the environment.
2. Control the proportion of feeding
The proportion of chicken manure added in pig feed should be controlled within 40%, and the proportion in sow feed should not exceed 20%. Pig manure is fed to chickens and the scale of breeding is determined by 1:20.
