Yila rabbit breeding
Yi La matching line meat rabbit is a hybrid breed cultivated by the French European Rabbit Industry Company in the late 1970s. It is bred by nine original varieties after breeding experiments with different hybrid combinations. One of the most remarkable characteristics of this breed is its high meat yield, which can reach 59%. It is the highest meat rabbit breed at present, with fresh and tender meat, and the average adult commercial rabbit weighs 4.5 kilograms. After decades of breeding, it has become one of the main varieties of meat rabbits in the market. Yuncheng developed earlier in our province, and the breeding of Yila rabbits has developed well at present. First of all, it is necessary to provide a suitable environment for house feeding and breeding Yila rabbits.
The general temperature of Yila rabbit requires 5 to 30 ℃, the most suitable temperature, 15 to 25 ℃, the relative humidity of this breed is 60% to 70%, and the other is light, the need for light is 14 hours to 16 hours a day, in the case of insufficient light in winter, some lamps can be installed in the rabbit house to replenish light manually.
To raise Yila rabbits, breeding rabbits must be raised in a single cage, and commercial rabbits should not be overcrowded. Overcrowding will cause adverse effects on rabbits and affect their growth rate. Yila rabbit is a herbivore, so the feed is mainly green fodder and concentrate fodder, but there is a lack of green fodder in winter and spring, so we can properly feed more concentrate fodder, which is mainly made of soybean meal, corn, wheat bran and so on. At the same time, feed more carrots.
Yila rabbit is a small breeding breed, which is more suitable for farmers. Because Yila rabbit makes use of the advantages of hybridization, it also has the advantages of stable genetic performance, less diseases and high feed conversion rate, with a feed-to-meat ratio of 2.8 to 1. In raising Yila rabbits, very little labor is needed. Generally, one person can undertake the task of raising 500 or 600 rabbits, which can be used as a reference project for farmers to choose and develop.

The activity law of snakes
What is the activity rule of ⒈ non-venomous snake? The activity of snakes has certain rules, and the distribution of snake species is different, and the activity rules of snakes are obviously different. In Shandong Province, for example, the activity of non-venomous snakes is roughly as follows: every year around the middle of April (solar calendar), when the outside temperature slowly rises to 15: 18 ℃, all kinds of snakes wake up from hibernation and crawl from their hibernating nests to the mouth of the cave or to the sunny place to bask in the sun. After May, when the temperature basically stabilized, snakes moved out of their nests, drank water, and mated. But for those who feed
