Free-range native chickens can use and expand the activity space of the chickens, so that the chickens can get sufficient movement. Therefore, the free-range chickens are very lively. The cut feathers are brighter than the captive chickens, and the meat taste is more tender than the captive chickens. However, judging from the current breeding situation of free-range chickens, there is also a certain degree of blindness. For this reason, many years of demonstration and research have been conducted on how to meet the nutritional needs of free-range chickens at different growth stages, and to more rationally choose suitable local ecological chicken breeding models. 1. The phased management method of "nutrition […]

1. China's nutritional challenges Take broiler breeding in China as an example. There are currently two main problems with high water content in corn and the use of old corn. Every year from October to March of the following year, high-moisture corn must be considered. If old corn is used, it should be considered whether its quality is reliable. In order to produce stable quality feed concentrates, the testing and monitoring procedures of the feed farm should be improved. If the feed formula is simple, it is easy to control the quality. In addition, we should also pay attention to the quality of dibasic calcium phosphate, heavy metal pollution, and

In today's livestock and poultry production, producers and nutritionists have paid great attention to dietary energy levels, amino acid quality concentrations and ratios, and the best supply of vitamins and trace elements. It is very important for livestock and poultry farms to benefit from selecting feed materials with suitable price, good quality and easy storage, and adopting appropriate raw material processing methods to prepare feed. However, there are some problems that need attention in the storage and processing technology of feed materials. Good feed storage and processing practices are often overlooked. The article will discuss the influence of storage conditions and processing technology on the nutritional value of feed ingredients

1. Cattle feed formula in farm (1) The formula of concentrated feed for feeder cattle weighing more than 400 kg is: corn 65%, bean cake 5%, cottonseed cake 15%, bran 11,5%, bone meal 1%. Table salt 1%, baking soda 1%, fragrance 0.5%.　　 (2) The feed formula for young cattle weighing more than 250 kg is: corn 60% and bean cake 10%. Cottonseed cake 20%, bran 5.5%, bone meal 1.5%, table salt 1%, baking soda 1%, flavoring agent 1%. Coarse fodder is mainly combined with silage corn stalks, beer stalks and white stalks. The silage corn stalks used are mainly the green stalks and green leaf corn stalks that are harvested

Wheat bran and wheat straw are important feeds in the main wheat producing areas, and rational use of them can play an important role in the development of animal husbandry. If it is used improperly, it will not only fail to exert its due effect, but also cause certain diseases of livestock and poultry and bring certain economic losses. 1. Wheat bran Wheat bran is a high-phosphorus and low-calcium feed, and its ratio of phosphorus to calcium is 4:1, which is the opposite of the physiological ratio of calcium to phosphorus required by livestock and poultry of 1.5-2:1. Feeding too much wheat bran can cause calcium and phosphorus imbalanced calcium

1. The basic feedstock for livestock uses corn stalks, straw, peanut vines, and sweet potato vines as the main raw materials. To make this kind of green plant feed, you only need to harvest, wash, dry, and crush the straw or vines in time. This type of feed is the basic feed for herbivorous animals and is mainly used for feeding dairy cows, beef cattle and herbivorous fish. When feeding, 40% to 60% of the total feed can be added, or whole feed can be fed. Adding about 40% corn stover powder or rice straw powder to fish feed can reduce feed costs by half. 2. Feed additives take fresh

Entering the winter, the farms began to feed cattle and sheep with silage, which is an indispensable high-quality feed for cattle and sheep.Today,Richi Machinery will tell you the following principles should be followed in choosing the opening time and the method of silage: 1. Choose a reasonable time for cellar opening. After 30-40 days of anaerobic fermentation, the cellar can be opened after the silage is completed. Under normal circumstances, opening the cellar before and after the beginning of winter is more conducive to the preservation of the whole cellar silage and the quality of the silage; 2. Choose a reasonable method of access. The silage must be taken every day

1. Improve feed utilization The heat, humidity, pressure and various mechanical effects during the puffing process generate low molecular weight products such as glucose, maltose, maltotriose and maltodextrin. Puffing process can increase the starch gelatinization degree, and the cell wall of the fiber structure is destroyed and It softens and releases partially enclosed and bound digestible substances. At the same time, the fat penetrates into the surface from the inside of the granule, so that the feed has a special flavor, improves the palatability, and increases the food intake rate. In addition, the protein in the vegetable protein feed can inactivate certain protease inhibitors such as antitrypsin and urease after

1. Commonly used rabbit feed ingredients (1) Green feed The green fodder eaten by rabbits includes leguminous forages, gramineous forages, leafy vegetables, rhizomes, etc., such as alfalfa, clover, ryegrass, bittersweet, sweet potato, agglomerate, pine herb and weeds, leaves, etc. (2) Coarse feed Roughage mainly includes green hay (grass, legumes and other green hay) and husks (rice straw, bean straw, corn stalk, etc.) straw. It is characterized by low water content, high crude fiber content, less digestible substances, poor palatability, and low digestibility. However, it has a wide source, large quantity and low price. It is one of the indispensable raw materials in rabbit feed. It is generally used in diets.

1. Choose high-quality chicken feed raw materials with sufficient local supply and stable quality The first requirement of formula design is to make full use of local resources, achieve cost savings, ensure the stability of formula quality and the continuity of formulas. 2. Comprehensively consider the factors affecting nutrition standards and choose a reasonable egg-to-energy ratio According to the breeding situation of laying hens, comprehensive consideration of various factors and external factors, in the process of formula design, refer to the nutritional standards and the characteristics of the nutritional composition of various raw materials, select a reasonable egg-to-energy ratio to achieve the best nutritional structure and the lowest feed breeding

The goals pursued by layer feed quality are long egg production peak period, high egg production rate, good egg quality, and good feed digestion and utilization, which can improve the feeding environment of layer farms and increase the economic and social benefits of layer feeding. How to achieve the above goals, how to choose raw materials, and how to formulate nutrition standards are all very important. 1. Selection of raw materials: (1) Scientific formulas must be protected by high-quality raw materials before they can be transformed into high-quality feed products. Farmers mostly buy raw materials from local distributors or directly purchase market raw materials. Due to unstable sources and large

In summer, there is a lot of rain and high temperature. The powdery mixed feed is easy to mold and deteriorate. If you use moldy feed to feed livestock and poultry, the milder will get sick, and the severer will cause poisoning and death, causing economic losses. Today, I will introduce several ways to store feed in summer:　 1, Hypoxia anti-mold method The feed is sealed and stored in a plastic bag, and the respiration of microorganisms is used to cause hypoxia in the bag to inhibit the growth of mold. 2, Calcium (sodium) propionate anti-mold method Add 100 grams of calcium propionate to every 100 kilograms of feed. The
