Study On Breeding And Feed Adaptability Of Ira Rabbit In The Background Of Characteristic Agriculture In Zhaotong Plateau

At present,China is the world's big rabbit breeding country,not only meat rabbit breeding conditions are appropriate,but also meat rabbit breeding efficiency is constantly improving,the deficiency is that there is a big room for improvement in breeding technology,especially compared with the developed countries in Europe and the United States.There is still a certain gap in meat rabbit breeding.At present,the characteristics of meat rabbit breeding in our country are mainly reflected in: 1 variety is numerous;2 quality is uneven;3 improved seed rate is not high;4 low productivity.And it is so that it becomes the key problem that restricts the development and breeding of rabbit.In recent years,the development of meat rabbit breeding in China has become increasingly large-scale,commercialized and intensive characteristics,making the role of meat rabbit breeding technology increasingly prominent.In this study,according to the characteristics of the plateau of Zhaotong Yunnan Yueyue Sheng Agriculture Co.Ltd Yila Rabbit was selected as the main rabbit of the company.In combination with the original breeding conditions,the feed raw material was adjusted and optimized.The model was optimized from the traditional production mode.In order to find out the best challenge of large-scale Ira rabbit breeding ground and improve the adaptability of Ira rabbit feed in plateau culture,the effects of different light time in experiment and breeding were studied.This study focuses on the key control points and core technical transformation of Chinese rabbit breeding from distributed breeding to standardized breeding.Compared with the advanced technology and excellent index in the developed European countries of rabbit breeding,we can find the blank and shortage in our country.To explore the effects of different breeding conditions on the performance of Yila rabbits and the growth performance of young rabbits,the effect of different diets of female rabbits on the growth performance of weaned rabbits,and to compare and analyze the total in and out mode of Yila rabbits with the common production mode.changes in parental rabbit reproduction and production.In the whole production process of fattening rabbits after weaning,the best technical standards and parameters of each feeding link were studied and discussed.At the same time,the nutritional level of the parents' diet of the female rabbits was explained;The feeding and management mode of the whole total feeding mode was compared with the traditional feeding management mode;The lighting time of the breeding rabbits after mating was optimized;And the effect of feeding standard on the production performance of the fattening Yila rabbits was compared.The purpose of this study is to provide technical support for the transformation of production patterns from traditional production to intensive and modern.Starting from the mass production of large-scale production enterprises,we constantly explore the data for integration with advanced technology and management methods abroad and pave the way to achieve excellent production targets and maximize economic benefits.In this study,the following conclusions were drawn through the experiment of feed nutrition: in the large-scale culture of Ira rabbit,adopting the mode of full in and out,not only helps to improve the lactation ability of Ira rabbit,but also improves the survival rate of Ira rabbit.When the following conditions were met,the ira rabbit mother rabbit had the best lactation power: 1 feed protein content 17%?18%;2 energy demand range between 10.5?11 MJ/kg;3 fiber level about 13%;and 4 lysine level about 1%.In the contrast experiment of culture pattern,we found that the whole-in-out model was used to breed rabbits on 35 and 70 days respectively.At the age of weaning,the yield rate was much higher than that of the common breeding model,and P?0.01.The results of the estrus test showed that the female rabbits needed to add light 6 days before mating,and the light time was not less than 16 h,7 d after mating,which was the best light condition for the female rabbits to keep the estrus level effectively.It can bring many economic benefits by adopting the whole-in-out model,but it is necessary to do a good job of daily management and improve the palatability of meat rabbits.In the same period of estrus,the best time to light is the female Light should be added six days before planting,and the daily light time is 16 hours,7 days after planting to start reducing light.
