What should beginners pay attention to when raising ground beetles?
Feeding scale: different feeding scales yield different benefits per unit area. Generally speaking, the smaller the feeding scale, the higher the cost, the lower the breeding benefit, and the greater the breeding risk. But the scale should not be too large either. Considering both input and output, it is recommended: if ground

Several Principles for Feeding in Macrobrachium nipponense Aquaculture
The freshwater shrimp (Macrobrachium nipponense) has tender flesh, a delicious taste and high nutritional value, and is one of the aquatic products deeply loved by the general public. In recent years its price has remained high, and market demand is strong. In recent years, Lianshui County has vigorously promoted freshwater shrimp farming, and the freshwater shrimp farming area has reached more than 8,000 mu. Scientific feeding is a key link in raising freshwater shrimp well. In the work of bringing fishery science and technology into households, it is often found that some farmers feed at will, causing some unnecessary waste. Based on years of experience and the actual situation of farming, the author has summarized five principles that should be mastered in feeding freshwater shrimp, for the reference of the broad community of farmers.

Key points for calf feeding and management in winter
The winter weather is cold, and calves are prone to catching cold and getting sick. Therefore, in winter, cows close to calving must be moved into the calving barn in time. The barn must have dedicated calf pens, and the feeding and management of winter calves must be strengthened. 1. A newborn calf's organs are not fully developed.

How should a domestic ostrich farm be laid out? Master these design principles
According to use and function, an ostrich breeding farm can usually be divided into a production area, an administration area and a staff living area. The production area can further be divided into the rearing area for breeding birds and young birds (over 3~6 months of age), the incubation area, the brooding area, the feed processing and storage area, and the new

How should sika deer be grazed during the breeding process?
With the rapid development of our country's economy, people have new demands in their lives, and a brand-new industry has appeared before people: sika deer breeding, taking the path to rapid wealth. So how should grazing be done? 1. Spring: from 5-9 and 14-18 each day, in early spring graze on sunny slopes and in late spring on shady slopes, and as far as possible graze in shrub areas where ice and snow melt early and there are many leaves, or on barren hillside land. From mid-to-late May, graze in tall meadow gullies and ponds and along riverbanks where willow shrubs grow thickly. 2. Summer: pasture grass is lush, the weather is hot with frequent storms, and there are many gadflies at noon, so according to the seasonal climate characteristics and the deer's habit of foraging at dawn and dusk, graze at both ends of the day and extend the midday rest period, with daily times of 4-9 and 15-19. 3. Autumn: the climate gradually becomes cool and grass seeds gradually mature, having relatively high nutritional value, making it a good season for does and growing deer to put on autumn fat. The grazing grounds are grassland, shrub forest and sunny slopes of barren hills, etc., daily from 7-11 and 13-17 in the afternoon. 4. Winter: choose wind-sheltered, sunny hillside gullies and ponds or open areas among the forest for grazing once a day from 9-14. And on days of strong wind and snow and in the severe cold of January, it is best to stop grazing.

Tibetan Mastiff Calcium Supplementation Requires Care: A Few Points Breeders Should Know
Calcium supplementation is an issue that cannot be ignored. If you want your beloved mastiff to grow healthy and imposing, with a beautiful physique and strong, agile limbs, you must supplement calcium at the right time and in the right amount. The following suggestions are for reference only: When is calcium supplementation needed? For large dogs like the Tibetan Mastiff, the larger the breed, the faster it grows, and the greater its calcium requirement. For puppies, the calcium contained in ordinary puppy food can hardly meet their growth needs. If you feed your mastiff homemade food, then you should pay even more attention to supplementing calcium in a timely manner. In addition, if your mastiff has long been eating animal liver or has meat as its staple food, then it should also be given an appropriate amount of calcium supplementation. This is because such foods not only have a very low calcium content, but also contain high concentrations of vitamin A. Long-term intake of high concentrations of vitamin A by dogs can inhibit calcium absorption. Therefore, you should immediately stop the long-term habit of feeding liver and promptly supplement calcium for it. After a mastiff enters adulthood, if it is fed dog food, there is no need for separate calcium supplementation. This is because during this period, the growth and development of the dog's bones and other organs have basically stopped, and its calcium requirement is very small. If it is a stud dog or a female dog during pregnancy and lactation, it still needs a large amount of calcium supplementation, because semen, fetuses during the embryonic stage, and milk will all cause a large amount of calcium to be lost from the body. If it cannot be replenished in time, calcium from the body's calcium pool will be drawn upon, causing osteoporosis. How should calcium be supplemented for mastiffs? There is no obvious difference between the methods of calcium supplementation for dogs and for people. Generally speaking, calcium products for human use are also suitable for dogs. In addition, drinking more milk or eating some dairy products and cartilage foods in daily life, and reducing the intake of foods high in vitamin A such as liver, are also beneficial for calcium supplementation. If a mastiff has already shown symptoms of calcium deficiency, then medication should be used. It is recommended to choose relatively inexpensive calcium carbonate and calcium lactate while injecting vitamin D3 and orally taking vitamin D2 and vitamin D3. Of course, if conditions permit, you can also choose some imported-brand pet calcium products, because these products are relatively more professional. Methods for supplementing calcium for young mastiffs Some people believe that feeding all meat can make puppies grow strong, but this is actually the wrong approach. Eating only meat not only cannot make puppies strong, but instead, due to indigestion and difficulty absorbing it, can cause most puppies to develop diarrhea. Although meat contains a lot of protein, it has relatively little vitamin A, vitamin D, vitamin E, and iodine. At the same time, meat has little calcium and much phosphorus. Long-term meat eating can easily cause an imbalance in the calcium-to-phosphorus ratio in puppies' bodies, resulting in skeletal disorders and making lameness likely. For large dogs, it is even more inadvisable to feed large amounts of meat too early, otherwise it may cause the front limbs to become bent. Puppies' feed should be supplemented with calcium powder and vitamins, which are necessary for the growth of teeth and bones. Especially for purebred dogs with larger frames, calcium is even more needed during the puppy stage. Usually, for growing puppies under one year old, the daily amount of calcium powder supplementation is about one teaspoon per 2 kg of body weight. As age increases, the amount of calcium powder and the dosage should be increased proportionally. After one year of age, because the puppy has entered maturity and the growth of teeth and bones has stabilized, the required amount of calcium powder is relatively reduced, and the dosage is about one teaspoon per 15 kg of body weight. However, there should be an appropriate amount of outdoor exercise every day, with exposure to ultraviolet rays, so as to facilitate calcium absorption.

How should the rearing of blue peafowl chicks be regulated
Blue peafowl chicks have a relatively poor ability to regulate humidity by themselves, and artificial brooding, whether on the ground or in cages, requires relatively high and stable humidity. No matter the season, great attention must be paid to keeping the brooding house warm. Brooding with underground flue heating is the most commonly used brooding and heating method in rural areas of northern China.
