Three methods to identify diseased rabbits
A look: the sick rabbit is mentally depressed, the body is thin, the bones are exposed, the coat is dishevelled, lack of luster, and does not change hair according to the hair changing season. Healthy rabbits have strong appetite and fast feeding speed, while diseased rabbits have poor appetite and slow feeding speed or refuse to eat. The feces of healthy rabbits are granular, oval, uniform in size and smooth in surface. If dry, hard and small faeces appear, it means constipation and should be fed more green and succulent feed; if feces are found to be tadpole-shaped or soft, which is a sign of indigestion, charcoal powder and yeast slices should be added to the feed; if the feces are stacked and

What is the harm of calcium deficiency in dogs
If there is insufficient calcium supplement in puppies, there may be valgus of ribs, deformation of wrist joint and elbow joint of forelimb, O-shaped legs in small dogs, and serious deformation of forelimbs in large and medium-sized dogs. If found to be not timely, improper treatment may also cause permanent claw or claudication. In addition, the age of 2 to 3 months is an important period for intervertebral disc formation in puppies. If calcium is deficient at this time, some breeds prone to intervertebral disc disease (such as Peking Dog, Xishi Dog, Pagodle, Poodle, etc.) will occur in adulthood, causing lifelong pain.

The time and conditions of artificial cultivation of queen bee
The new bees bred in the same year have completely replaced the old bees that overwintered, and after entering the period of development and growth, the population is strong, so they can be prepared to breed the king artificially. In the north, when the daytime temperature is stable above 20 degrees Celsius in early summer, when there are honey sources, especially when there are abundant powder sources, drones begin to come out of the house one after another, and it is better to breed in this period. North China is generally in May. This can ensure the quality of the queen bee, and can use the new queen bee to replace the aging queen bee as soon as possible, and the colony with the queen bee in that year will not have natural clustering. Using the new queen bee cultivated in the early stage to divide the bee artificially.

Feeding restriction methods and matters needing attention of pigs
1. Feed restriction methods and matters needing attention should be considered to achieve the best feed-to-meat ratio. Pigs before 50 kg should not be used, and after 50 kg, different feed restrictions can be made according to the breed. The points for attention in feed restriction are as follows: pigs in the same column must have similar body weight, otherwise it will easily lead to the law of the jungle; sufficient feed trough and pigsty area are required so that pigs can eat feed at the same time (the average feed trough for fattening pigs weighing 60 to 100 kilograms should be 30 cm long); excessive feed restriction will prolong the age of sale, so the building capacity of the pig house should be the same.
