Utilization and treatment of rabbit dung

Rabbit manure can not only be used as breeding feed, but also can be used as ideal fertilizer after special processing. It not only improves the benefit of raising rabbits, but also reduces the environmental pollution. The following editor introduces the utilization and treatment of rabbit dung, in order to provide reference for improving the utilization rate of dung-free.

Rabbit manure is a high quality organic fertilizer.

1. Rabbit feces contain more nitrogen, phosphorus and potassium than other livestock and poultry feces, as well as a variety of trace elements and vitamins. One adult rabbit can accumulate about 10 kg of fertilizer a year, and the fecal excretion of 10 adult rabbits is equivalent to that of a pig. Every 100 kg of rabbit dung is equivalent to 10.85 kg of ammonium sulfate, 10.90 kg of calcium superphosphate and 1.79 kg of potassium sulfate.

2. Rabbit feces and urine can improve soil aggregate structure, improve soil fertility, kill insects and sterilize, resist drought and preserve soil moisture. The soil with rabbit dung urine can reduce the above-ground and underground pests such as mole cricket, red spider and armyworm. Applying rare rabbit manure urine at cotton seedling stage can prevent and cure the ground tiger infecting cotton seedlings, and fumigating with rabbit dung urine can kill Bombyx mori and make silkworm cocoon harvest. The application of rabbit manure can increase the yield of all kinds of crops.

3. Urea, ammonia nitrogen, potassium and phosphorus in rabbit feces and urine can be directly absorbed and utilized by plants, but the undigested proteins can not be directly used by plants and can only be absorbed after fermentation and ripening. Therefore, rabbit feces and urine must be processed to improve its fertilizer efficiency and utilization rate.

Treatment of rabbit feces and urine

1. Stacking fermentation

The rabbit feces and urine and residual forage are piled together, and water is added at the same time, so that the water content reaches about 50%. Pile it into a circle, seal it with mud and let it ferment. After several weeks, the temperature inside can reach more than 50 degrees. After the temperature drops, open the dung pile, and then let it ferment for a period of time, generally in order to turn brown, no odor and sour taste, soft hands, not touch the hands, that is, it has rotted well.

2. Make rabbit feces and urine.

Remove the weeds from the collected rabbit feces and urine, put water into the cylinder at 1:7 (seal the cylinder mouth with plastic or soil), ferment in 3-4 days in summer and autumn, and 10-15 days in winter and spring, and filter out the residue with sacks or gauze, that is, rabbit and fecal urine. Adding 10 times water dilution and loading the sprayer into the crop leaf surface, applying 510 kg per 667 square meters to the leaf surface of barley, wheat and rice at heading stage can obviously increase the yield.

3. Making granulated fertilizer

Remove the forage grass and impurities from the rabbit feces and urine, dry them and put them into a plastic bag and fasten the mouth of the bag for use. This kind of granular fertilizer is easy to preserve, strong fertility and easy to use, and can be used as hole fertilizer in fruit trees, tea gardens and vegetables. When used as base fertilizer, it not only has remarkable fertilizer effect, but also has the functions of drought resistance, soil moisture conservation, insecticidal and sterilization.

Application of rabbit dung in aquiculture

Rabbit feces contain 9.2% crude protein, 1.7% crude fat, 52% nitrogen-free extract, 8.2% total ash, nicotinic acid, pantothenic acid, vitamin B12 and so on. Practice has proved that rabbit dung is a good feed. Feeding rabbit dung to livestock and poultry fish can be well digested, absorbed and utilized, for example:

1. Feed rabbit dung to pigs

There are many reports about feeding pigs with rabbit dung at home and abroad, and many rabbit farmers feed pigs with rabbit dung, which saves concentrate and increases economic income. There are the following methods for comprehensive rabbit farmers to feed pigs with rabbit dung:

① fed pigs with fresh rabbit dung directly. Boil water in a large pot (add water according to the proportion of water dung at 1:2), boil the fresh rabbit dung in the pot for 5 minutes, then add the mixed concentrate feed (rabbit dung accounts for 30%, 40%, 60%, 70%) and continue to boil for 3 minutes. And stir the rabbit dung balls to make the dung mix evenly and form a thick porridge sample. After being warm and cool, it can be fed 3 times or 4 times a day. Feeding rabbit dung to fattening pigs can save 50 kilograms of mixed concentrate per pig, and feeding sows can save 175 kilograms of mixed concentrate. 1520 adult rabbit droppings can be used for one sow.

There are two fermentation methods for feeding pigs after ② fermentation:

One is to remove the sundries from the collected fresh rabbit dung, dry and smash it into a cylinder, add 6 to 7 kg of water and 0.1 to 0.2 kg of salt for every 10 kg of dried rabbit dung, stir evenly, fill the cylinder 80% full, and then seal and ferment the cylinder mouth with plastic film. Fermentation time: 2-3 days in summer, 5-10 days in spring and autumn, 15-20 days in winter.

Second, the collected fresh rabbit dung to remove sundries, crushed and mixed with feed (aquatic plants, vegetable leaves, Robinia pseudoacacia leaves, etc.), dung and green feed according to 3:1. Then add 0.5% salt and 1.0% salt and an appropriate amount of water, add water to hold hands without dripping water, loosen your hand and spread it again, then pack it into a cylinder and compact it, adding 2-3 cm thick wheat bran, rice bran, etc., so as to keep warm. Generally filled with 80%, and finally the cylinder mouth with plastic film or clay sealed fermentation, hot days after 2-3 days, cold days after 8-15 days fermentation. After fermentation, it has sour flavor and good palatability, which pigs like to eat.

③ dried and crushed and fed to pigs: this method is relatively simple. The fresh rabbit dung to be collected will be removed from the grass and impurities, dried in the sun and crushed, together with the mixed concentrate will be directly used to feed pigs, the manure-to-material ratio can be 3:7.

2. Feeding rabbit dung to chickens

There are few reports about feeding rabbit dung to chickens at home and abroad. Through the experiment of feeding Avian broilers with dried rabbit dung instead of 17.5% corn in Gaocheng livestock farm in Hebei province, there was no significant difference between the test group and the control group, indicating that rabbit dung can replace part of corn to feed broilers.

3. Feed the fish with rabbit dung

Shexian Animal Husbandry and Fisheries Bureau of Hebei Province once fed fish with rabbit slaughtering leftovers (including rabbit dung and part of rabbit stomach and intestines), which greatly increased the yield. The method is as follows: put the slaughtered leftovers (including faeces in the gastrointestinal tract) in a human pot, add water and then add corn flour, wheat bran, grain bran, etc., and continue to boil for 5 minutes (60% of the leftovers and about 40% of the mixed concentrate) to make it thicker. Take out the mixed concentrate composed of corn flour, wheat bran and grain bran on the cement floor and dry it into pellet feed to feed the carp with good palatability and fast growth. After 90 days of raising, the yield of carp was increased by about 50% per hectare.
