The use value of animal manure is related to the content of nutrients. The chicken has a short digestive tract. The feed stays in it for a short time. A considerable part of the nutrients are not digested and excreted with feces. Therefore, chicken manure is richer in nutrients and minerals than other animal manures. And has a broader development and application prospects.
So, how can chicken manure be effectively used in small chicken farms?
Q: I heard that some places use chicken manure as feed to feed livestock. Is there any scientific basis for this?
A: Yes, chicken manure can be used to feed livestock and poultry after proper processing. Or, it can be used as an “additive ingredient” for livestock and poultry feed. This is because the chicken’s intestines are short and excreted quickly, so about two-thirds of the nutrients in the feed are not absorbed and excreted with the feces. According to analysis, chicken manure contains crude protein 24 to 3%, crude fat 17 to 33%, carbohydrate 30 to 36%, and also contains a variety of minerals and vitamins. According to the traditional method, chicken manure is often used directly as farmland fertilizer, because there is still a lot of energy in chicken manure that is not fully utilized, which is very uneconomical. In fact, chicken manure can be used instead of part of the feed to feed livestock and poultry. In this way, some of the active ingredients in chicken manure have been further utilized.
Q: How is chicken manure used as organic fertilizer?
A: The decomposed chicken manure can be mixed with the single fertilizer and a certain amount of binder. Then It can be made into an organic-inorganic briquette (granular) fertilizer using a briquette machine (briquettesolution.com) or a granulator. The fertilizer is using a natural drying method on drying which save lots of energy. Chicken manure contains abundant crude protein and mineral nutrients, so it has wider use value as feed or fertilizer.
Q: Then we also said that chicken manure can be used as feed, but chicken manure is smelly and dirty. How to process it?
A: At present, although there are different processing methods in different places, basically there are three kinds.
1. Drying method
Spread the collected chicken manure in a clean place, let the sun dry or dry naturally.
The way of grasping the proper humidity, grab a chicken manure into your hand, feel dry and loose.
Then remove the impurity and you can use it. If you want to make pellet feed, you can use a certain proportion of sorghum and bran with fresh chicken manure, remove the impurity and dry it naturally, then you can use it.
2. silage fermentation method
The fresh chicken manure is poured into the silage according to the weight ratio of 20%. After being evenly mixed, it is put into the tank or the cement pool and compacted. The general fermentation time is 4-6 hours in summer, 1 day in spring and autumn, and 8 to 4 days in winter.
The fermented feed is yellow-green, resembles yellow sauce, and has a winey aroma.
3. semi-dry lactic acid fermentation method
First, the chicken manure is dried to 70%, then crushed, sieved, removed from large pieces and sundries, and then blended with 10-15% of wheat bran. Stir well, put in a plastic bag, and fasten the bag. Let it ferment under anaerobic conditions. When the chicken manure has a distiller’s taste, it can be poured out. With this method, the key is to master the fermentation temperature and time. The temperature is above 20 °C, and the fermentation is 1-2 days. If the temperature is low, it is best to ferment in the tank or barrel of the house, and cover it to prevent gas outflow. When the temperature is close to zero, heat preservation measures are needed. The temperature of fermentation should not be high, 45-55 °C is more suitable.
Chicken manure within two or three days after fermentation can be dried and preserved if not used.
Q: Which of those methods is most suitable?
A: The drying method is relatively simple and is currently widely used. However, depending on the specific situation, such as in the rainy season, it is difficult to use the drying method, and the silage fermentation method can be used. For farmers with more staff and careful management, it is best to use semi-dry lactic acid fermentation.
Q: Please tell us about the use of processed chicken manure.
A: The processed chicken manure can not only feed livestock and poultry, but also serve as a fish feed. The amount of material to be mixed into the feed should be flexibly adjusted according to the type of livestock, age and body size, and it can be slowly adapted to the small to many. The specific use is as follows:
Feed the pigs
5-30% of chicken manure can be added to the pig’s diet. Piglets should be less, sows should be more, and regular pigs should be between the two. The pigs were stopped feeding twenty days before the slaughter.
Feeding cattle and sheep
For fattening cattle, add 20-50% chicken manure to the diet, 10-25% for cows, 30-50% for sheep, and 10-25% for dairy goats.
Feed the fish
Chicken manure, such as directly feeding fish ponds, is easy to cause waste. It is advisable to use 20% chicken manure and 80% bait, and mix it to make pellet feed. The effect of feeding fish is not inferior to that of bean cake.
Feed the ducks
In duckling feed, the amount of chicken manure should not exceed 10%, and the young and middle-aged ducks can increase to 15-20%.
Q: The methods you introduce are mostly used by the farmers. However, what issues should be paid attention to during the processing and use of chicken manure?
A: From the perspective of processing and using chicken manure, the following should be noted:
1. Collect chicken manure
Spread a 6 cm thick rice chaff powder on the floor of the house to bind the discharged chicken manure to rice chaff powder, and then collect and clean the chicken manure regularly.
2. Guarantee the quality of chicken manure
Fresh chicken manure has good palatability and less nutrient loss. It is best to collect it once a day and process it in time. Prevent the quality reducing or deterioration of chicken manure after a long period of time.
3. Reasonably mix the feed
The chicken manure contains more crude protein and cellulose, and should be matched with corn, wheat and other feeds with high energy and less cellulose. For example, when feeding pigs and feeding cattle, a certain amount of concentrate feed can be guaranteed every day, and the insufficient part is supplemented with chicken manure.
4. Strengthen management
It is necessary to supplement high-quality green fodder for livestock, poultry and fish that feed chicken manure, regularly supply clean drinking water, timely inject preventive vaccines, remove parasites from outside the body, and do a good job in sanitation.
