Processing Methods and Technical Key Points for Fox, Raccoon Dog and Mink Feed
Fur-bearing animals such as mink and foxes have well-developed canine teeth, a short digestive tract, a small stomach volume and no cecum, food passes through the digestive tract quickly, and their digestive glands secrete little amylase but more lipase. Therefore, their feed should be based mainly on animal feed, and in particular animal protein feed should account for a very large proportion of the daily ration. Thus, the feed processing and preparation methods for mink and foxes have distinctive characteristics, which are introduced below: 1. Material selection. Remove large pieces of fat from meat feed, remove the gallbladder and thyroid from livestock and poultry offal, and pick out lumps, impurities or foreign matter from dry animal powder feed and grain powder.

A Detailed Guide to the Processing and Preparation Methods of Raccoon Dog Feed
The feed of raccoon dogs includes animal-based feed, plant-based feed and supplementary feed. The supply and composition of feed have a great influence on the health, reproduction and fur quality of raccoon dogs. To practice scientific raccoon dog farming, one must understand the effects of the nutrients in feed on raccoon dogs, so as to reasonably and correctly formulate and process feed, and obtain the best economic benefits with the least feed consumption. Therefore, the processing and preparation of feed is very important. I. Feed Processing (1) Processing of fish and meat feed Fresh marine mixed fish, and the meat, liver,

Fish feeding is affected by 6 situations, and farmers need to pay attention
In the process of intensive aquaculture production, the management of feed feeding is one of the main links in the entire production management, and during the feed feeding process, the phenomenon of reduced feed intake by fish often occurs. Based on different situations in production, the author analyzes the reasons for reduced feed intake by farmed fish as follows: The first situation: fish are suffering from disease, causing reduced feed intake by fish. For example, when crucian carp inner spore disease, grass carp three diseases, channel catfish hemorrhage disease, enteritis and other diseases occur, the feed intake of fish is significantly reduced. When grass carp fingerlings and crucian carp have large numbers of wheel

Chum Salmon Farming Techniques and Key Points of Feeding Management
[Local names] Ma-ha-yu, Ma-ha-yu, salmon, Ma-gao-yu. [Morphological characteristics] The body is generally about 60 cm long. The body is elongated and laterally compressed, gradually rising behind the head. The head is large and laterally compressed. The mouth is large. The tip of the snout protrudes and curves slightly, resembling a bird's beak; during the breeding season the protrusion is most pronounced in males, curving toward each other like pincers so that the upper and lower jaws do not meet. The eyes are small. The gill openings are large. The scales are small and fine. The lateral line is distinct. Behind the dorsal fin there is a very small adipose fin, opposite the anal fin. The caudal fin is slightly forked. Body color varies considerably; when first entering fresh water from the sea,

What are the advantages of using extruded floating feed to farm the four major Chinese carps?
Farming grass carp (Ctenopharyngodon idella) with extruded floating complete compound feed has many advantages, such as lowering costs, protecting the aquaculture water environment, and high utilization rate. In countries with advanced aquaculture technology such as the United States and Japan, to meet the needs of the environment and fishery production, floating aquatic feed has been widely used since the 1980s. In recent years, China has also vigorously promoted the use of floating aquatic feed, developing rapidly, and many famous, special and high-quality aquatic products have already used it in large quantities, but in the use of extruded floating fish feed to farm the four major Chinese carps, there is still

How to Raise Adult Turtles? Detailed Explanation of Feeding Methods and Technical Key Points
The area of an adult turtle pond should preferably be 100 sq m, and about 10 juvenile turtles can be stocked per sq m. The pond water for adult turtles should be kept light green (transparency of about 30 cm). If the transparency is too high, the turtles will feel insecure; if the transparency is too low, the water will be brownish green, the water quality will be too fertile, and it will easily cause eutrophication, which is also bad for raising turtles. The feeding method for adult turtles varies by season. In spring and autumn, when the water temperature is low, adult turtles do not come out much in the early morning or evening, so they should be fed at 10 a.m.; in midsummer

Adding Eucommia ulmoides to pig feed can speed up pig weight gain
Process the Chinese herbal medicine Eucommia ulmoides into powder or fine granules and add it to the daily diet of fattening pigs at a ratio of 0.2 percent to 0.3 percent, and good results of fast weight gain and a high lean meat rate can be achieved. According to experiments, compared with fattening pigs not given Eucommia ulmoides, their weight gain rate is about 11 percent to 16 percent faster, about 0.24 kg of feed is saved per 1 kg of weight gain, feed conversion rate is increased by 5.4 percent, and carcass lean meat rate is increased by more than 30 percent, because Eucommia ulmoides can promote cell division and the development of muscle fibers and increase the collagen content in muscle

Five Considerations for Formulating Rabbit Feed
Select ingredients according to local conditions. The selected raw materials must not only meet the nutritional needs of domestic rabbits, but also be adapted to local conditions, using locally available forage as much as possible. Pay attention to the diversity of feed. Combining multiple feeds can play a role in nutritional complementation. Pay attention to seasonal differences. In most areas of China, green fodder is scarce in winter and spring, and domestic rabbits are prone to vitamin deficiency, so supplementation should be noted. Pay attention to the palatability of feed. Domestic rabbits like bitter chicory, alfalfa (Medicago sativa), and soybean, and refuse moldy-smelling and fishy-smelling forage. Pay attention to the

Potato waste turned into treasure, can be processed into protein feed
Recently, researchers at Harbin Institute of Technology have made encouraging progress in research on using discarded potato waste to produce single-cell protein feed. The researchers not only screened out an excellent combination of bacterial strains for producing cell protein, but also designed and formulated a complete process route for producing single-cell protein feed from potato waste. The use of potato waste with juice for liquid fermentation to produce cell protein is the first proposal and application of its kind both domestically and internationally. China produces more than 70 million tons of potatoes annually, and more than 3.4 million tons of potato waste remain after starch processing.

Method for Making River Crab Feed from Potatoes
Using potatoes to make river crab feed has the advantages of widely available raw materials, low cost, good palatability and rich nutrition, and river crabs like to eat it and grow readily. At the same time, this feed-making method is relatively simple; it can be produced on a large scale with machinery or made by hand, so potato crab feed has broad application value. The key processing and feeding techniques are introduced below for the reference of aquaculture farmers. Process flow: material selection -> cleaning -> cutting into pieces -> steaming -> crushing -> ingredient mixing -> shaping -> drying. Processing techniques: (1) Material selection. Choose potatoes free of pests and diseases, without sprouting,
