Feed costs account for about 60% to 70% of the total chicken production cost, so how to improve feed utilization is particularly important. Here are some effective ways to improve the utilization of chicken feed:
Scientifically formulated feed. (1) Select the raw materials to prepare the feed, pay attention to the quality and palatability of the raw materials, for those feed ingredients with poor characteristics and poor palatability such as blood meal, leather powder, feather powder, cotton aphid (cake), rapeseed (cake), sesame Cakes, grass powder, and dregs should be processed in advance and their use in feed should be limited. (2) The raw materials used should be of good quality, and the raw materials that are mildewed and deteriorated should not be used as raw materials for compound feed. Also pay attention to the selection of feed ingredients that are not contaminated with pesticides or other toxic or hazardous substances. (3) Attention should be paid to the diversification of feed, and use as many feed ingredients as possible to prepare, so that the nutritional complementation between various raw materials can be fully utilized to ensure the improvement of nutrients and to improve the digestibility and nutrients of feed. Utilization. (4) When formulating feed, it is necessary to select suitable feed ingredients according to the digestive physiology characteristics of various chickens, especially to control the content of crude fiber in the feed. As the content of crude fiber in the diet increases, daily gain and feed utilization will decrease. The crude fiber content is preferably not more than 5%.
The processing and modulation of feed should be reasonable. Feed processing and preparation methods have a great impact on feed digestibility. Heat treatment processing such as granulation or extrusion improves nutrient utilization and feed utilization. If over-processed, it will reduce nutrient availability and feed utilization. . The heat treatment of soybeans and the like destroys the trypsin inhibitor and improves the utilization rate of the feed. Stirring when the feed is mixed will reduce the digestibility of the feed. The particle size of the feed also has an impact on feed utilization. Excessive feed size will reduce feed digestibility. Too small a feed size will reduce palatability and feed intake and increase the incidence of gastric ulcers.
Adopt a scientific feeding method. Feeding methods are different depending on the feeding method. The feed conversion ratio has been improved compared to dry and wet feed and liquid feed and dry feed, but higher feed intake can lead to increased carcass fat. Adequate and clean drinking water is also very important for improving feed utilization.
Improve the feeding environment. Environmental conditions can also affect feed conversion efficiency. For example, the optimum temperature for laying hens is 18 to 20 ° C. When the temperature is lowered, the feed intake is increased, and most of the feed energy will be used for heat production instead of laying eggs. If the temperature is too high, the feed intake is reduced. Changes in humidity, ventilation, harmful gases, light, etc. can also affect feed utilization.
Improve the level of feeding management. Feeding management also affects feed utilization. If the overcrowding of laying hens can significantly impair the production performance, the feed intake and feed remuneration will decrease. Under the conditions of feeding, the production performance of the smaller groups was significantly improved. Good manual management will also achieve better production efficiency.
Do a good job in epidemic prevention and health care. It is necessary to develop an epidemic prevention program and manage it according to procedures to maximize the production performance of the flock. If unhealthy chickens are found in production, they should be treated or eliminated in time.
Appropriate use of feed additives. In the production practice, the use of some enzyme preparations, probiotics, traditional Chinese medicine preparations, etc. can improve the feed utilization and production performance of chickens.
