This invention discloses an automatic feeding device for free-range chickens. It utilizes the chickens' natural instinct to seek food, feeding them at set times via a feeder that circulates along a predetermined track, thus driving continuous movement and improving the meat quality. The device is characterized by a feed bin located directly above the track, with power units positioned near the bottom at both ends. Each power unit has wheels at both ends, which are in contact with the sides of the track. The feed bin consists of an upper and lower section. The upper section is hollow, while the lower section contains a storage slot where a battery pack is placed. A flow divider is located within the upper section, extending downwards to connect with the top of the lower section. The flow divider's thickness increases from top to bottom. A control box is positioned on top of the power units and is fixed to the feed bin. A feeding hopper is located at the opening of the feed bin and is connected to the interior of the feed bin.

The present application belongs to the technical field of aquaculture, and particularly relates to a segmented type of pompano breeding method. The segmented type of breeding method provided by the present application supplies nutrition accurately according to the requirements of different growth stages of pompano, and significantly improves the growth speed. Through the optimization of water temperature and light conditions in different stages, the growth speed of pompano is significantly accelerated, thereby shortening the breeding cycle. The addition of licorice powder and melatonin in the feed further enhances the immunity of pompano and reduces the use of drugs. Through the segmented type of breeding, the present application improves the unit yield and survival rate of pompano, and significantly improves the economic benefits.

The invention belongs to the technical field of livestock and poultry breeding and feed formulas, and particularly relates to feed for improving the meat quality of Songliao black pigs by cooperatively replacing soybean meal with fermented miscellaneous meal and application. The feed is prepared from the following components in parts by mass: 60 to 65 parts of corn, 8 to 12 parts of fermented peanut meal, 6 to 10 parts of fermented sesame seed meal, 3 to 5 parts of soybean meal, 4 to 6 parts of bran, 3 to 5 parts of rice bran, 1 to 2 parts of fish meal, 0.8 to 1.2 parts of stone powder, 0.6 to 0.9 part of calcium hydrogen phosphate, 0.3 to 0.5 part of table salt, 0.2 to 0.4 part of amino acid premix, 0.1 to 0.2 part of vitamin premix, 0.1 to 0.2 part of mineral premix and 0.05 to 0.1 part of compound enzyme preparation, wherein the total mass of the feed is 100 parts. Wherein the mass ratio of the fermented peanut meal to the fermented sesame meal is (1.0-1.5): 1, the proportion of the fermented peanut meal and the fermented sesame meal for synergistically replacing the soybean meal is 70%-85%, the crude protein content of the feed is kept at 16%-18%, and the feed meets the protein requirement of the Songliao black pigs in the fattening period. The feed can meet the growth and metabolism requirements of the Songliao black pigs, and the meat quality is remarkably improved while the breeding cost is reduced.

The invention discloses a single-bacterium fermentation compounding method of cattle feed, and relates to the technical field of feed fermentation. Comprising the following steps: preparing a single-bacterium fermentation bacterial material, the single-bacterium fermentation bacterial material comprises 42.25-47.25 parts of wheat bran, 19-21 parts of soybean meal, 14.25-15.75 parts of corn flour, 19-21 parts of rice hull powder and 0.003-0.005 part of a bacterial liquid, and strains used by the bacterial liquid comprise six probiotics including saccharomyces cerevisiae, bacillus subtilis, bacillus licheniformis, lactobacillus plantarum, enterococcus faecalis and lactobacillus acidophilus; the six probiotics are subjected to independent solid fermentation, the prepared fermentation fungus materials are compounded in proportion to obtain a compound fermentation fungus material, and the compound fermentation fungus material is fed according to cows with different weights. Through the technical route of single-bacterium independent fermentation, the problem of mutual inhibition generated during compound fermentation of various strains is avoided, high-density propagation of the strains in the fermentation process is guaranteed, the compounded feed can meet the nutritional requirements of cattle in different stages, and the yield of the cattle is improved. The feed digestion and absorption rate is effectively improved, the cattle immunity is enhanced, and the growth performance is promoted.

The invention provides a cage culture method for Jinhua, and relates to the technical field of aquaculture. The method comprises the specific steps that S1, fry grading and box separation preparation is conducted, specifically, robust, injury-free and disease-free Jinhu fries are selected, grading is conducted according to the fries with different body lengths, and the fries are put into different specifications of net cages; s2, domestication period: alternately irradiating the fries in the net cage by using blue light and green light sources, reducing dissolved oxygen by stages, feeding nutritional feed, and domesticating; s3, variable-temperature circulation treatment, wherein in the domestication period, variable-temperature circulation treatment is conducted on the net cage; s4, in a culture period, fixing a light source, adjusting the intensity of the light source, performing oxygenation, and feeding pellet feed; and S5, when the weight of the golden tiger spot is greater than 600g, taking the golden tiger spot out of the box and marketing. According to the net cage culture method, the feeding period is shortened, the utilization rate of the net cage is increased, the meat quality of the finally obtained Jinghuaozhu is high, the social benefit and the economic benefit of the Jinghuaozhu are increased, and the application prospect is good.
