Farmers solve the problem of poultry protein feed

The shortage of protein and beverages is the biggest problem faced by farmers in the breeding industry. The following substances can be used as additional supplements:

In the rapeseed cake, the crude protein content was 31.5%, digestible protein was 25.6%, crude fat was 10.2%, crude fiber was 11.1%, nitrogen-free extract was 27.9%, calcium was 0.82%, phosphorus was 0.46%, and amino acid and manganese were also contained. , zinc, copper and other trace elements, rapeseed cake is also toxic, can be mixed with 1% ferrous sulfate heating detoxification, according to 10% of the diet fed to poison.

The cotton cake cake contains 41.6% crude protein, 33.9% digestible protein, 11% crude fiber, 4.3% crude fat, 0.1% calcium, and 1.2% phosphorus. The crude protein content is 4 times higher than that of barley and corn, and Contains a variety of amino acids and trace elements such as manganese, zinc, copper, etc., but cottonseed cake contains gossypol poison, to 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% to 12% of the diet.

The stem body contains 66.5% crude protein, 12.8% crude fat, and 8.2% carbohydrates. The domestic farming quail is an important way to solve animal protein feed sources. Manure is odorless, odorless, and can feed chickens.

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 to 20 grams of fresh quail daily to meet the needs of animal protein. The fly larva should be washed first, then boiled with boiling water and then fed.

The blood meal coagulates the blood of the livestock and then cooks it under high temperature, removes the juice, and is dried and crushed. Blood meal contains 83.8% crude protein, contains lysine, arginine, methionine, cystine and other amino acids, vitamin B1, B12 is also very rich. It also contains trace elements such as iron and copper necessary for poultry. However, blood meal deficiency vitamins A and D, calcium, phosphorus, etc. are also less, poor digestibility, must pay attention to the amount of collocation.

Silkworm cocoon is a high-protein feed containing 68.3% crude protein, 56.5% digestible protein, 28.8% crude fat, 1.2% calcium, 0.73% phosphorus, and contains thiamine, riboflavin, vitamin E and various amino acids. In particular, the methionine content is the best, and it can be used as a chicken methionine adjusted feed.

Feather meal Poultry feathers after slaughter are 83% nitrogen compound, 12% moisture, 1.5% fat, 1.5% minerals. It is a high-grade new type feed. It is cooked in high temperature and high pressure, dried and ground into powder. feed. It contains not only abundant protein and more than 10 kinds of amino acids, but also a kind of "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.

Pine needle powder Pine needle powder made from pine needles is a multi-effect feed additive. It contains various amino acids, proteins, fats, trace elements, phytoalexins and vitamins and other nutrients. 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% to 4.5% of pine needle powder to the pig diet can increase the growth by 15% to 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 dry with steam (preferably within 1 minute to avoid loss of some of the nutrients), then cool and then crush.

An Analytical Balance (often called a "lab balance") is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product.[citation needed] Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure from causing an error in reading. Single pan mechanical substitution balance maintains consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added.[citation needed]

Electronic analytical scales measure the force needed to counter the mass being measured rather than using actual masses. As such they must have calibration adjustments made to compensate for gravitational differences. They use an electromagnet to generate a force to counter the sample being measured and outputs the result by measuring the force needed to achieve balance. Such measurement device is called electromagnetic force restoration sensor.
