How is poultry feed intake calculated? A summary of calculation formulas
817 crossbred broiler: starting from the first day, increase by 2.5 grams per day. That is, the feed intake of 1000 817 crossbred broilers at 35 days of age is: 2.5g x 35d x 1000 birds ÷ 500 grams = ...

How to feed silkworms well in summer and autumn? All the nutritional formulas are here
The main feed for silkworms is mulberry leaves. Because the quality of mulberry leaves varies greatly from season to season, it has a considerable impact on cocoon yield and quality. If nutritional supplements are fed to summer and autumn silkworms, the yield can be increased by 10%-20%. The formula techniques are introduced as follows: 1. Additive formulas and feeding methods. (1) Glucose solution additive. During the silkworm rearing period, if there is continuous rainy weather, the mulberry leaves are tender in texture due to insufficient sunlight, high in moisture content, and low in carbohydrates. At this time, a 5% glucose solution can be sprayed on the harvested mulberry leaves, and after they are air-dried, they can be fed to the silkworms, which can

Feed Formulation and Processing Techniques for Medicinal Silkworm Larvae Infected with Beauveria bassiana
Currently, medicinal silkworm larvae infected with Beauveria bassiana are in strong demand on the Chinese medicinal herb market, and raising and processing them is profitable. The methods for raising and processing them are: 1. Rearing the mature silkworms. Raising and processing medicinal silkworm larvae infected with Beauveria bassiana should be carried out as a specialized operation in non-cocoon-producing areas, so as to avoid a devastating impact on cocoon silkworms. The raising and processing can be carried out throughout the year. As for the feed, besides a small amount of mulberry leaves, more evening primrose, Jiancan grass, white clover, cup plant (Silphium perfoliatum) and the like can be added to replace mulberry leaves, so as to supplement the shortage of mulberry leaves and reduce feeding costs. For

How to formulate lactating sow feed scientifically
Sows bear very heavy responsibilities. Lactating sows in particular must not only supply the nutrients they need themselves, but also supply the breast milk on which newborn piglets depend for survival, growth and development. Moreover, lactating sows in the high-temperature season face an even more unfavorable living and production environment, and heat stress is a severe challenge for farrowing sows. Therefore, how to scientifically formulate the summer diet of lactating sows and strengthen feeding management should be a problem that pig producers must actively consider and focus on solving. Optimizing the formulation and raising the energy level should

Detailed Explanation of Fox Feed Formulation Methods and Raw Material Ratios
The fox's digestive tract is shorter than that of the raccoon dog, its dental chewing surface is less developed than that of the raccoon dog, and the fox's large colon and cecum are also less developed than those of the raccoon dog. The time food takes to pass through the digestive tract is only 25-30 hours for the fox, while the raccoon dog needs about 40-50 hours. Therefore, the fox's ability to digest and absorb nutrients from feed is weaker than that of the raccoon dog. The fox has higher requirements for animal-based feed and vitamins than the raccoon dog. The fox's demand for feed is greatest in summer and weakens in winter. Nutritional needs differ across different biological periods; generally, they are higher during the breeding season than during the non-breeding season, and the diet should be based mainly on animal-based feed, mixed with some plant-based feed.

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

What to do about damp-heat in pigs? Adjusting the feed formula is a key measure
1. Adjust the feed formula to increase pig feed intake. 1. Under high-temperature conditions, in order to reduce heat increment and reduce the burden of heat dissipation, feed intake will inevitably decrease, causing insufficient intake of energy, protein and other nutrients in pigs. Making necessary adjustments to the feed formula has become one of the effective measures to overcome heat stress. ① The greater the heat increment of nutrients, the more severe the heat stress after feeding. Oil and fat have a small volume, high net energy value and low heat increment, making them an ideal energy source for pigs under high-temperature conditions. Oil and fat can be added to the feed within 5%

Analysis of Issues in the Formulation and Use of Complete Feed for Ussuri Raccoon Dogs
The raccoon dog is an animal endemic to East Asia, mainly found in China, Russia, Korea, Japan, Mongolia and other countries, and is divided into many subspecies. The Ussuri raccoon dog is mainly distributed in China's Heilongjiang Province, the eastern and southeastern regions of Jilin Province, and northeastern Korea. At present, the vast majority of raccoon dogs bred in captivity in China are Ussuri raccoon dogs originating from Heilongjiang Province. The raccoon dog is one of the fur-bearing animals with high economic value. Compared with foxes and mink, it has the advantages of bearing more cubs, a high survival rate, being easy to raise, and having a stable market; therefore, in recent years the number of raccoon dogs raised in China has steadily increased year by year, with good momentum
