Processing and Utilization of Potatoes
I. As Feed Both the tubers and the starch residue of potatoes can be fed to livestock and poultry. According to experiments, feeding 50 kg of potatoes to pigs can increase meat by 2.5 kg; feeding dairy cows can produce 40 kg of milk or 3.5 kg of butter. Feeding each chicken an average of 71 g each of chopped, cooked potatoes and mixed feed per day can increase annual egg production by 30 to 50 eggs and save 20 kg of concentrated feed. II. Extracting Starch Every 100 kg of potatoes generally yields 12.15 kg of starch. The extraction process is relatively simple: first wash the potatoes, then mechanically crush, grind,

Development and Utilization Value and Methods of Kernel Apricot Flesh
I. Dried Apricot Processing 1. Process flow: apricot flesh → washing → sulfur fumigation → drying → finished product 2. Technical points: (1) Washing. Select flesh that is uniform in appearance, fully ripe, with no fuzz on the fruit surface, small in fruit size and thick in flesh; wash clean with water and drain off the moisture. (2) Sulfur fumigation. Send the material baskets or bamboo trays holding the apricot slices onto the wooden racks in the fumigation room, pour the burning charcoal into the iron pan in the center of the fumigation room, quickly sprinkle sulfur (3-4 kg of sulfur per 1000 kg of apricot slices) onto the charcoal, then leave the fumigation room immediately

Comprehensive Utilization Methods of Fish Fingerling Ponds During the Winter Fallow Period
Raising market-size fish: Using winter-fallow fingerling ponds to raise one season of market-size fish can both increase production and help ease the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are combined into ponds, so as to make full use of the growing period. Stocking rate is calculated at a maximum water depth of 2 m, generally 125-150 kg per mu. The stocking ratio is generally about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp.

How to Improve the Utilization Rate of Winter-Idle Fish Fry Ponds
After the winter pond consolidation until the release of summer fry the following year, most fish fry ponds have an idle period of about half a year. If they are comprehensively utilized, the utilization rate and economic benefits of the fish fry ponds can be greatly improved. Four methods of utilizing winter-idle fish fry ponds are introduced below. Raising market-size fish: Using winter-idle fish fry ponds to raise one season of market-size fish can both increase output and help regulate the "summer shortage" aquatic product market. Because the rearing period is relatively short and the temperature is relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fish fry are consolidated into ponds, so as to make full use of the growing period. The stocking amount is calculated at a maximum water depth of about 2 m, generally 125 kg to 150 kg per mu. For the stocking ratio, generally silver carp account for about 40%, bighead carp about 10%, grass carp and bream about 30%, and black carp and common carp about 20%. Release @#@233@#@ large-size fingerlings, generally silver carp and bighead carp above 250 g, grass carp above 500 g, bream above 100 g, black carp above 1000 g, and common carp above 250 g. 2. Strengthen management. Fertilize promptly after the fish are stocked. Fertilization should mainly use organic fertilizer to ensure that the pond water has a certain fertility. In winter, choose clear and warm weather and feed once every 2 to 3 days, with the feeding amount at about 20% of the usual amount. In spring, as the water temperature rises, increase the feeding amount and maintain good water quality, so that the fish school maintains a relatively high growth rate and reaches the market size on schedule.

Breeding and Utilization of the Japonica Hybrid Rice Hanyou 1027
Hanyou 1027 is a new japonica hybrid rice combination bred by the institute in 1985 by crossing the Hanfeng male-sterile line with the T1027 restorer line. In 1986, at the institute's experimental farm, on 1.62 mu the yield was 581.7 kg per mu, an increase of 11.8% over Hanfeng. In 1988, on 1.2 mu at the institute, the yield was 604.6 kg per mu, an increase of 22.0% over Xiushui 04. As a single-season rice in Shanghai, the combination takes 153-156 days; as a double-season rice in Changsha and Hangzhou, 122-142 days.

A Detailed Explanation of Processing Techniques and Utilization Methods for Dog By-products
The processed dog skin has good cold-resistant and moisture-proof performance and an attractive fur color, and can be made into vests, mattresses, and so on, and is very effective for the waist soreness and cold legs of elderly people and rheumatism patients. 1. Processing: During processing, first clean the meat, greasy matter, feces, dirt, and blood off the dog skin, lay it flat on a wooden board, and rub it with coarse sandcloth or a brick until the coarse hair roots are slightly visible. Then use 500 g of alum, add 5000 ml of water, boil, pour into a basin, and after it cools, fully immerse the dog skin, take it out after about 24 hours, place it hair-side down on

Methods and Techniques for Rational Utilization of the Three Wheat Feeds
Wheat bran, wheat chaff and wheat straw are collectively known as the three wheat feeds, and they are important feeds in the main wheat-producing areas. Rational utilization of the three wheat feeds can promote the development of the livestock industry. If used improperly, they will not only fail to produce the desired effect, but will also cause livestock and poultry to contract certain diseases, resulting in economic losses. Wheat bran belongs to the high-phosphorus, low-calcium feed category, and the ratio of phosphorus to calcium it contains is 4:1, which is the opposite of the physiological calcium-to-phosphorus ratio required by livestock and poultry, which is 1.5:1 to 2:1. Feeding too much wheat bran can cause calcium deficiency disease due to an imbalanced calcium-to-phosphorus ratio, such as rickets in young animals, osteomalacia in adult animals
