10 low-cost protein poultry feeds
Feed is the material basis for the growth and development of poultry, but the main ingredient in the feed, protein egg, is relatively scarce. The commonly used fishmeal, soybeans, bean cakes, etc., are too costly. Here are a few of the easy-to-use and economical protein feeds.
1. In the rapeseed cake rapeseed cake, the crude protein content was 31.5%, the digestible protein was 25.6%, the crude fat was 10.2%, the crude fiber was 11.1%, the nitrogen-free extract was 27.9%, the calcium was 0.82%, and the phosphorus was 0.46%. Contains amino acids and trace elements such as manganese, zinc, and copper. The rapeseed cake is also toxic. It can be heated and detoxified with 1% ferrous sulfate. After detoxification, it is fed at 10% of the diet.
Second, peanut shell powder peanut shell powder contains a lot of fat, starch, sugar, vitamins, minerals and other nutrients. The peanut shells are crushed into powder and mixed in the feed to feed the chickens. The chicken production rate can be increased by 20% to 40%. The broilers can gain weight quickly, and the meat rate can be increased by about 20%.
Third, the sunflower dish sunflower dish after washing and drying, dry crushed can be used as animal feed. It contains digestive energy of 8778kj per 1kg dry weight, digestible crude protein 78g, in addition also contains a certain amount of calcium, phosphorus, vitamins, not only is a good energy feed, but also contains high protein feed.
Fourth, cottonseed cake cottonseed cake contains crude protein 41.6%, digestible protein 33.9%, crude fiber 11%, crude fat 4.3%, calcium 0.1%, phosphorus 1.2%, its crude protein content is higher than barley, corn four times, and Contains a variety of amino acids and trace elements such as manganese, zinc, copper, etc., but cottonseed cake contains gossypol poison, can be used after detoxification. Detoxification method: After crushing, add 0.5% ferrous sulfate, and add 1.5% lime water to mix and heat. The amount of feed can only account for 8% -12% of the diet.
5. Silkworm cocoon is a high-protein feed containing 68.3% of crude protein, 56.5% of digestible protein, 28.8% of crude fat, 1.2% of calcium, 0.73% of phosphorus, and contains thiamine, riboflavin, vitamin e and various Amino acids, especially methionine, are the best and can be used as chicken methionine to adjust feeds.
6. The dry body of earthworms and cockroaches contains 66.5% of crude protein, 12.8% of crude fat, and 8.2% of carbohydrates. Family breeding clams are an important way to solve animal protein feed sources. Manure is odorless and odorless, and it is also a good feed for chickens.
7. The dried fly maggot powder contains 59.39% of protein and 12.6% of fat. It also contains all kinds of essential amino acids. Each laying hen only needs 15-20 grams of fresh quail daily, which can meet the needs of animal protein. The fly larva should be washed first, then boiled with boiling water and then fed.
Eight, blood meal will be blood after the animal's blood clot after high-temperature cooking, pressure in addition to juice, dry crushed. Blood meal suitable for 83.8% of crude protein, containing lysine, arginine, methionine, cystine and other amino acids, containing vitamins b1, b12 is also very rich. It also contains iron, copper and other trace elements necessary for raising birds. However, blood meal lacks vitamins a and d, calcium and phosphorus are also less, poor digestibility, must pay attention to the amount of collocation.
Nine, Feather Powder The feathers of poultry after slaughter are 83% nitrogen, 12% moisture, 1.5% fat, and 1.5% minerals. It is a new type of high-grade feed, which is cooked in high temperature and high pressure, dried and ground into powder. Serve Good feed. It contains not only abundant proteins and more than 10 kinds of amino acids, but also a "growth hormone" that can promote the growth and development of poultry. Therefore, it is a good feed for poultry such as chickens and ducks. Feeding chickens and ducks with feather meal can increase the lean meat of chickens and ducks, reduce fat and fat, increase the egg production rate by about 20%, and prevent chickens from eating food.
Ten pine needle powder
Feeding birds with pine needles works well. Pine needle powder made from pine needles is a multi-effect feed additive containing various nutrients such as amino acids, proteins, fats, trace elements, phytoalexins and vitamins. According to the comparative test, adding 5% pine needle powder to the formulated grains of laying hens can increase the egg production rate by 13.8%. Adding 2.5%-4.5% pine needle powder to the pig diet can increase the growth by 15%-40%. . There are two ways to make pine needles. One is to put it in a place where there is no direct sunlight for ventilation, and it is dried to a moisture content of less than 20%. Then it is crushed with a pulverizer. The second is to use steam to dry (preferably in 0 minutes to dry, so as not to lose part of the nutrients), after drying and then crush.
