Eight non-food feeds for pigs

With the rapid development of China's animal husbandry, the demand for feed grains is increasing day by day. To alleviate the contradiction between humans, animals, and grain, it is imperative to develop non-food feeds. And the development of non-food feed can also effectively reduce the cost of production and increase the economic benefits of farmers. Here are some non-food feeds suitable for pigs.

First, chicken manure

Chicken manure is a kind of protein supplement with high quality and low price. Dry manure contains 15% - 30% of crude protein, 10% - 16% of crude fiber, 8% - 10% of various amino acids, and 1 kg of chicken. The crude protein content of feces is equivalent to 600 grams of concentrate. However, the crude protein in chicken manure contains 50% of non-protein nitrogen and is present in the form of uric acid. The energy is low and the ash content is as high as 25%-35%. Therefore, we must pay attention to treatment methods to increase pig utilization.

1, the processing of chicken manure

1 Drying: Spread the chicken excrement evenly on the concrete floor, air dry naturally, make the moisture content of the chicken manure below 13%, and the condition can be dried by a dryer.

2 Fermentation: Add rice bran, bran, grass powder, crop straw powder, etc. to the chicken manure, add proper amount of water, put it in a cylinder, pit or plastic bag, press tightly and seal it tightly, make acid for 3 to 5 days, ie Can be used to feed pigs.

3 Silage: Mix 60% of chicken manure, 30% of straw powder, 10% of bran, maintain humidity 60%, and store silage for 30--50 days.

2, the amount of chicken manure

Piglets can be added from 5% to 10%; fattening pigs can be added from 15% to 30%. However, when chicken manure is used as feed, one should collect fresh chicken manure without pollution in the non-epidemic area; second, more grain feed should be added to increase palatability and mineral balance; thirdly, the chicken manure contains high ash content. Note that the total amount of ash in the diet should not exceed the critical level; Fourth, chicken droppings should be stopped 15 days before the fat pigs are slaughtered.

Second, rabbit feces

Rabbit manure has a high nutritional value. According to the American "Rabbit Practical Research" (1984) report, 7.9% of dried rabbit manure contains 92.1% of dry matter. The anhydrous rabbit manure contained 20.3% of crude protein, including 5.7% of digestible crude protein, 2.6% of ethyl ether extract, 16.6% of crude fiber, 40.7% of nitrogen-free extract, and 10.7% of mineral matter. The crude protein content of 2 kg of rabbit manure is equivalent to 1 kg of hay. Therefore, it is of great practical significance to develop and utilize rabbit manure as a new feed resource.

1, rabbit feces processing

The rabbit manure as a feed, first of all should go to the mud, go to miscellaneous, not moldy, no pollution. The processing method generally uses the following method:

1 Drying method: Collect clean rabbit excrement, dry it and pulverize it, lay a thin layer on the concrete floor, expose it to sunlight for more than 3 hours, and mix it in the feed to feed the pig. Use this method in summer

2 Boiling method: Collect fresh rabbit feces, then add the bran and other feed, boil 10 - 15 minutes, mix in the feed and feed the pig. This method is mostly used in winter.

3 soaking method: The dried rabbit manure crush into a cylinder, pots and other containers, add boiling water, stir into a paste to feed.

4 Direct feeding method: Collect fresh rabbit excrement on the day and mix it directly into feed for feeding pigs.

5 chemical treatment method: The dried rabbit manure was crushed, 200 ml per kg of formaldehyde solution was added and then dried and fed. This method can kill pathogenic microorganisms in rabbit feces without destroying nutrients.

6 alkali treatment method: the sun-dried rabbit feces into the tank, according to 50 kg of rabbit manure by adding 40% of the caustic soda solution 100 kg soaked for 24 hours, remove and put in clean water, drain after Can be used to feed pigs.

7 Lactic acid fermentation method: The rabbit feces were exposed to sunlight for 2 - 3 days, and the water was sprayed after crushing. It is advisable to add water to the rabbit manure in a group. Then into the water tank or plastic bag, compaction seals for anaerobic acid. It can be used when the fermentation temperature reaches 40 degrees Celsius. Summer usually takes 1-2 days and winter time is slightly longer. This method can be bactericidal, but also improve the palatability of rabbit feces.

8 Silage Fermentation Method: The collected rabbit manure is crushed and mixed with grass and vegetables, and appropriate amount of water is added to pick up the principle of no dripping. Then put the cylinder or cellar compaction, spread the bran, straw, rice bran, etc. for insulation, sealed for 1- 2 days later. Fermented rabbit manure is fragrant and delicious. This method is mostly used in summer and autumn.

2, rabbit feces added

The pigs fed with the processed rabbit feces are usually fed with 10%-15% of the piglets, and the finishing pigs are added with 15%-25%. However, the amount added in the livestock diet should be determined by the amount of bran, rice bran, etc. added to the rabbit manure, and the additional bran can be increased appropriately. After fermentation, the rabbit feces are loose and soft, with aromas and palatability. Pigs are more willing to eat. However, feed should be stopped 20 days before the finishing pigs are slaughtered.
