CATDOLL : CATDOLL: How many kilograms of feed should be fed to 500 kilograms of fry per day?

1. How many kilograms of feed should be fed to 500 kilograms of fish fry per day?

This depends on the size of the fry. Generally, about 130 kilograms are enough. Such fry are usually around one kilogram.

The food intake of fry is about 4% of their body weight. Please calculate the total amount of feed according to the body weight of the fry and feed them three times a day.

If the grass carp weighs half a catty, you can give it about 100 to 150 grams of feed every day. If they weigh one catty, you can give them 200 to 300 grams of feed every day.

2. How much feed should koi be fed in a day?

Science shows that in koi breeding, the most suitable living temperature for koi is 20-27 degrees Celsius. If it exceeds 30 degrees, the appetite of koi will weaken. According to the specific situation, breeders can feed koi three to four times a day, but they must ensure that the koi finish eating within 5-10 minutes. At the same time, in hot summer or cold winter, breeders should pay attention to feeding 1-2 times a day, reducing the feeding amount appropriately, and try to finish eating within 10 minutes, and it is best to have no residue. In the hot summer, you can feed in advance, at 7 or 8 in the morning, before the water temperature rises. In the cold winter, the water temperature is mostly below 7 degrees, so the feeding time can be at noon when the light time is strong, and the feeding should be stopped when the water temperature is 1-2 degrees.

Generally, we can feed koi once a day when we raise them personally. It is best to feed the koi until they are 70% to 80% full. In spring and autumn, when the water temperature is suitable, we should maintain sufficient bait to ensure that the koi are full and eat well. If the koi shows signs of looking for food after one feeding, we should feed them a second time. Within one or two days when we change the water for the koi, the amount of bait should be slightly less. After the water turns green, we should feed them regularly to ensure that the koi are full. If it is the breeding season, the amount of bait for koi can be reduced by one-half or one-third; the amount of bait for weak and sick koi can be reduced by two-thirds to reduce the occurrence of koi diseases.

3. How much feed should a 20-pound piglet be fed in a day?

It should be controlled at about 0.8 catties. When it reaches 45 catties, it should be measured at 2-2.5 catties. Feed 3 times a day to see how much the pig eats. About 1 catties of feed per day. Generally speaking, the dry matter (excluding water) consumed by pigs every day accounts for about 5% of their body weight; the air-dried feed (about 12-14% water content) accounts for about 6% of their body weight; the green feed can account for 20-30% of their body weight every day (can be calculated as 25%).

4. How many kilograms of feed should a sow be fed per day?

A. Sows are fully fed (ad libitum) when their body weight is 30-60 kg.

B. Sows weighing 60-100 kg or more: Feed appropriately, with a basic daily feed intake of 2-2.5 kg

C; Two weeks before breeding: starting from 14 days before breeding, implement aphrodisiac feeding, improve the daily diet level, increase the feeding amount and allow free feeding).

5. How many kilograms of feed should be fed to medium-sized pigs per day?

When raising pigs, you need to calculate the amount of feed they eat. The amount of feed they eat is different at different stages, so mastering the amount of feed they eat can ensure that the pigs can grow better. If it is a 1-5kg pig, the daily intake of air-dried feed is 0.2kg; if it is a 5-10kg pig, it is 0.46kg; if it is a 10-20kg pig, it is 0.91kg; if it is a 20-60kg pig, it is about 1.69kg.

How to calculate the amount of feed consumed by fattening pigs?

The amount of feed for fattening pigs is proportional to the growth of the pigs. Generally, the daily feeding amount for each pig is 5% of the body weight for piglets (over 60 catties); 4% for medium piglets (60-120 catties); and 3% for large pigs. For example, for a 50-catties piglet, the daily feeding amount is (50 catties × 5%), about 2.5 catties, and for a 100-catties medium pig, the daily feeding amount is (100 catties × 4%), about 4 catties.

Generally, pigs under 40 catties should be fed a fixed amount on time tomorrow. Pigs over 40 catties can eat freely. It should be noted that for pigs that eat freely, it is best to eat all the food in the dry feed trough in one day, and it should not exceed two days at most. There are always dead corners in the feed trough, and the feed is easy to mold and deteriorate. Also, if there is always food stored every day, the pigs will get sick and don't like to eat, and it is not possible to see it in time. Also, the pigs have no sense of hunger and eat less.

If you want your pigs to grow fast, it is best to let them eat all the feed when their heads turn black for pigs weighing more than 150 pounds, and feed them wet feed once around 9 o'clock in the evening. The effect is very good.

What are the feeding methods for fattening pigs?

The fattening pig pens should be disinfected regularly, and the pigs should be raised in pens according to their size. Feeding should be done at regular times and in fixed quantities so that the fattening pigs can form a fixed diet. It is better to feed in the form of raw dry feed. This method can improve the feed utilization rate of fattening pigs and meet commercial standards earlier.

1. Selection of fattening pig breeds

The three-way hybrid is a two-way sow produced by the cross between Landrace and Yorkshire, and Duroc is used as the terminal father. The piglets produced are recognized as excellent fattening pigs both internationally and domestically. Each pig farm or professional household can decide according to their own economic strength. Those with strong strength can use imported foreign breeds, such as Duroc Changda and Duroc Dachang, which are called foreign three-way piglets for fattening. Or go to some large-scale fine breed pig farms to buy three-way piglets for fattening. Those with weaker economic strength can use local excellent sows and imported pig breeds to crossbreed, and use the hybrid offspring of Changdaben and Duroc Daben to produce commercial pigs, which are called three-way.

2. How to select fattening piglets

First, check the uniformity. The more uniform the growth and development of the piglets, the better the quality. Second, check the weight. For piglets of similar age, the larger the weaning weight, the better. Third, check the coat color. The coat color of the piglets should be shiny. Fourth, check the health status. They should be strong and sturdy, and in good spirits. Fifth, check whether the ears are oily. Oily ears indicate good health and nutritional status. Sixth, check the distance between the last pair of nipples. Those that are far away are generally willing to eat, grow fast, and are easy to raise. Seventh, check the glossiness of the hoof shell. Good ones indicate that they are healthy and easy to raise. In short, the piglets are required to be good hybrids, in good health, and have good growth and development potential.

3. What should be done when new pigs enter the pen

1. First, clean the vacant pig house or pen thoroughly.

2. Use 2% to 3% caustic soda water to spray and rinse, scrub the walls, feeding troughs, floors, doors and windows. After disinfection for 1 to 2 hours, rinse with clean water.

3. After drying, use a spray such as Baidusha to disinfect. It is best to use a flame sterilizer to bake.

4. Before new pigs enter the pen, use anthelmintics to deworm the pigs inside and out.

4. Adjustment of the group for new pigs entering the pen

When purchasing pigs, they should be separated into pens according to the size, strength and breed of the piglets to facilitate feeding and management, and to avoid the big ones bullying the small ones, or the strong bullying the weak, which would affect the health of the pig herd.

5. Feeding of fattening pigs

1. The feeding of fattening pigs should be regular, quantitative and frequent, and should not be changed at will. Developing a fixed conditioned reflex is conducive to the full digestion and utilization of feed.

2. Feeding amount. It is better to feed pigs three times a day, and pigs under 25 kg can be fed four times a day. The feeding amount is the weight of the pig × 0.04. Small pigs should be fed more, and large pigs can be fed less. In practice, the best way to control the feeding amount of pigs is summarized in eight words: "eat until full, don't lick the trough". Let the pigs eat enough without leaving any feed. The sign of being full is that they don't lick the trough, and leaving some feed residue is a sign of not licking the trough.

3. Feeding method. The feed required for each pen should be evenly spread from one end of the trough to the other end. This is conducive to equal feed for each pig. It is also conducive to the timid pigs who cannot grab the trough to eat the feed from both ends, preventing individual pigs from becoming thin and losing weight.

4. Clean the feeding trough before feeding. Make sure to remove the feces and urine in the feeding trough before feeding, and never spread the feed with feces. Clean up the leftover feed after the pigs are full to prevent contamination and waste of feed.

5. There are many forms of feeding for fattening pigs, mainly dilute feed, wet feed and dry feed. Feeding too dilute feed will weaken the chewing function, dilute the digestive juice, and also affect the pigs' feed intake and weight gain. It is easy to have a "grass belly" and reduce the meat yield; wet feed is to wet the feed with 1 to 1.2 times water, and it is appropriate to hold the feed in your hand to ooze water, which is conducive to swallowing food and can complete the feeding work quickly; raw dry feed can prolong the time of chewing food in the mouth, so that the food and digestive juice are fully mixed, which is conducive to improving the meat yield of fattening pigs and is very popular in the live pig market.

6. Change feeds in time. The feeds for fattening pigs are divided into small pig feeds, which are fed before 30 kg; medium pig feeds are fed from 30 kg to 60 kg; and large pig feeds are fed from 60 kg to the stage of market release. Changing feeds on time can not only meet the needs of fattening pigs at different stages, but also reduce feed costs.

6. How much feed should be fed to 1,000 kilograms of fish in a day?

One thousand kilograms of fish eats 50 kilograms of feed a day, and the feed amount and fish weight are usually 1:20. Large-scale fish farming must pay attention to feeding, usually animal feed is used, which has a high protein content and is very helpful for the growth of fish.

In addition, plant-based feed should be used to provide energy and fiber for the fish, and mineral feed or additive feed should be used to increase the content of trace elements so that the fish can grow healthily.

7. How much feed should be fed to 600 kilograms of carp in a day?

600 jin of carp are fed 6 jin of feed a day. Because one qian of feed is fed for one jin of carp a day, so 600 jin of carp are fed 6 jin of feed a day.

8. How many fish can be fed with 140 kilograms of feed in a day?

A: Generally, 100 jin of fish can eat about 1.5 jin of feed. That is to say, if there are 100 jin of fish in the pond, you can feed them about 1.5 jin of feed, which is 100 to 1.5.

Similarly, 140 catties of feed can feed 9333 catties of river fish, that is to say, if the feed is 140 catties, it can feed 9333 catties of fish. If the pond has five acres of water surface and there are about 10,000 catties of fish, then 150 catties of feed is needed every day. How to calculate that 140 kg of feed can feed nearly five acres of fish in the pond! Please review!

9. How many kilograms of feed should be fed to 1,000 pairs of free-range pigeons in a day?

It takes 800 kilograms of feed to raise 1,000 pairs of meat pigeons, because the basic daily diet for each pair of breeding pigeons is about 80g, and 1,000 pairs of pigeons consume about 800 kilograms of food every day. It usually takes 17-18 days of incubation from the time the hen lays eggs to produce a qualified meat pigeon, and the chicks can be sold after 25 days of brooding. The breeding period is relatively short, and each pair of squabs produced requires about 2 kilograms of food throughout the whole process. If a pair of breeding pigeons produces 18 squabs per year, a total of about 36 kilograms of feed is needed, and the total of the two grains is about 94 kilograms.

10. How many kilograms of feed should be fed to a 260-kilogram reserve sow per day?

A 260-pound sow is fed about 20 pounds a day! Sows cannot eat too well.
