Feeding livestock and poultry, feed costs account for approximately 60% to 70% of feed costs. To reduce feed costs, feed utilization must be increased. What measures should be taken in breeding to increase feed utilization has also become the focus of farmers. The following measures to a certain extent can give some help to farming friends.
Livestock and poultry activities are large, so as to maintain and meet the heat energy and various nutrient requirements in the metabolic process. Therefore, it is necessary to change the cattle and sheep to be kept in captivity for a long period of time, and to improve the free-range chicken for cage rearing.
At present, rural pig-raising habits are used to feed dilute foods. Due to excessive water intake, the pig's food intake is limited, and the digestibility of dry matter and feed utilization rate are reduced. According to experiments, pigs eat thinner, 27.1% more heat energy than eating condiment, so they should be changed to feed thick materials.
When livestock temperature is below 10°C, the heat loss is 28% higher than when the temperature is 10°C above zero, and when the temperature is below 4°C, the weight gain is reduced by approximately 50%, and the feed consumption per kilogram of weight gain is optimal. Increases the temperature by 2 times. In winter, livestock must be allowed to live in relatively dry and warm houses. Should scientifically deploy dietary nutrient levels. In the basic animal and poultry diets, supplements should be added to some amino acids, vitamins, minerals, insecticides and health care drugs. It can not only improve the full price of the diet, but also reduce the disease and promote the growth of livestock and poultry.
Improper feed processing methods often result in nutrient losses. The inclusion of antitrypsin and other substances in the legume diet will affect the digestion and absorption of the protein, but after heat treatment, the trypsin can be rendered ineffective, thereby increasing the utilization of the protein. The finer the cereal feed is, the higher the digestibility is, but too fine will reduce palatability. If the crushed grain feed is processed into pellet feed for livestock and poultry, the utilization rate of the feed can be increased by about 23%.
Protein feed is an indispensable nutrient for the growth and development of livestock and poultry. For monogastric animals, nitric acid and lysine are indispensable raw materials for the production of compound feed. According to the experiment, broilers were fed with a diet containing 18% crude protein, and lysine was added, and the weight gain was 24% more than without.
Poor storage of feed, feed value is not only reduced, but also prone to livestock and poultry poisoning, long-term feed will be due to fat deterioration and reduce the nutrients, including vitamin A, D, E is also easy to oxidation and reduce efficacy, so a purchase The feed should not be too much, and the purchased feed should also be shaded, ventilated, and moisture-proof.
With good selection, the consumption of materials will also decrease. A hybrid pig can increase daily weight gain by 10% to 30% and save about 10% to 15% of feed compared to purebred pigs.
