The forest products are rich in nutrients needed for the body of the farm animals. These nutrients have the functions of promoting growth, improving animal production performance and improving animal product quality in many aspects, and are natural green organic feed additives. It has been proved by the research and application of animal husbandry technicians that pine needles can be added to chicken feed to improve egg yellow color. Many forest products are used as livestock feed or feed additives to improve the quality of animal products.
Improve the color of meat and egg products. For example, pine needles contain 197 mg to 343 mg of carotene per kilogram, which can be used as a coloring agent to improve the egg yellow color. Feeding cattle, sheep, rabbits, geese and other herbivores with fresh pine leaves can significantly improve their skin and muscles. Color. Often used as animal color enhancer, such as locust leaves, phoenix leaves, amorpha, apple leaves, mulberry leaves, orange peel, spatholobus.
Increase the edible portion of animal products. The forest products can be added to the compound feed in proportion, which can effectively improve, perfect and balance the nutrient ratio of the compound feed, so that the nutritional level of the combined feed tends to be full price, giving full play to the animal production performance, increasing the lean rate and reducing the body. Improve the quality of products and improve the quality of nutrients. Adding 5% paulownia powder to the fattening pig feed can increase the pig weight gain rate by 32.63%, the carcass lean meat rate by 11.16%, body fat by 4.17%, and feed compensation by 22.29%. Adding 8% Amorpha fruticosa powder to the mutton sheep combined with the concentrate, the weight gain rate was 9.3% higher than that of the control group, the lean meat rate was increased by 7.21%, and the abdominal fat was decreased by 2.36%. Adding 3% poplar leaf powder to the feed of broiler chickens, the lean meat rate of the experimental group was 6.35% higher than that of the control chicken, and the abdominal fat was reduced by 2.47%. With 4% eucalyptus powder, the lean meat rate of chickens can be increased by 9.76% and the abdominal fat by 2.96%. Forest feed additives that can increase the lean meat rate of farmed animals include tea leaves, eucommia leaves, and ginkgo leaves.
Increase nutrition in animal products. According to the chicken farm test, 3% of discarded tea leaves were added to the chicken feed. The test results showed that the muscle contained vitamin E and vitamin A, which were 2.4 times and 2.2 times higher than that of ordinary chickens, and the oxidized lipid was reduced by 25%. According to repeated tests, the content of vitamin A, selenium and myogenic protein in the muscle of chickens increased by 57.3%, 8.9% and 9.1%, respectively, by adding 2% to 3% of pine leaf powder to the feed of broiler chickens.
Reduce harmful substances in animal products. Studies have shown that the addition of 500 mg of glycosides per kilogram of broiler diet to the antibiotic group has significantly reduced the levels of heavy metal cadmium and lead in muscle and liver of broilers, and increased muscle fat and amino acid content. Tea polyphenols extracted from tea are polyhydroxy phenolic compounds, which often form complexes with metal elements in animals and affect the absorption of these elements. Tea polyphenols usually do not affect the absorption of iron, and combine copper, lead, cadmium, magnesium, zinc and other metals into the gastrointestinal tract of the animal to form a complex, so that it cannot be absorbed by the body and prevent harmful metal ions from remaining in the tissue.
Improve the flavor of animal products. Hedgehog leaves, apple leaves, etc. as feed additives, both contain higher crude protein and a variety of amino acids, a variety of forest products containing meat protein crystal fragrance, fresh related amino acids. Moreover, the leaves, the resin and the skin contain volatile oils of different scent types, and these volatile oils contribute to the aroma and fresh odor of animal meat, milk and egg products. Some of the fruit seeds of the tree contain a certain amount of fatty acids, which can improve the flavor and health effects of the meat.

projects.
Construction attention
1. Try to shop on the ground before paving, and divide the plaza tiles with different color numbers and sizes according to the paving form.
2. Side paving, side seaming, solid base layer and full joints can make the paving tile more durable and avoid rupture during use.
3. Tap the tile surface after paving to balance the brick bottom with the paving surface to avoid the phenomenon of empty drums.
4. During the paving process, measure with a level to ensure the level of square tile paving.
5. During the construction process, the cement or other sticky materials left on the tile surface should be wiped clean to avoid too long surface contamination and difficult to clean.
6. After the paving, check it. After curing, the paving tile can be used normally.
