Abstract:The purpose of this study was to investigate the effect of culture of Acerermonium Terricola (ATC) on weight gain of whitefeathered broiler chickens. In this experiment, 200 1-day-old broiler chickens were randomly divided into 2 groups. The control group was fed the basal diet, and the Acerermonium Terricola group was fed with 0.20% ATC in the basal diet. The test period was 42 days. During this period, we recorded the body weight every week, analyzed the average daily gain, and counted the feed consumption of each group during the test period, and calculated the breeding benefits brought by the gain. The results showed that during the test period, compared with the control group, the average body weight of the Acerermonium Terricola group was significantly increased by 13.23% (P<0.01); the average daily weight gain was significantly increased by 13.53% (P<0.01). The profit of Acerermonium Terricola group was 14.06% higher than that of the control group. This shows that adding ATC in the feed can significantly increase the average daily gain of broilers. This increases breeding benefits and is beneficial to the antibioticfree and breeding of poultry animals.

Abstract:This paper explores the effects of programmed freezing and vitrification on the recovery rate and developmental potential of mouse GV stage oocytes and twocell stage embryos. We compared different cryopreservation methods of mouse oocytes and early embryos to provide a reference for subsequent Avang sheep embryo cryopreservation. In this study, programmed freezing and vitrification techniques were used to freeze mouse GV stage oocytes and twocell stage embryos respectively, and culture them after recovery. The recovery rate, maturity rate and blastocyst rate after different freezing treatments were compared. The programmed freezing recovery rate (48.00% ± 5.29%) of mouse GV stage oocytes was significantly lower than the vitrification recovery rate (65.00% ± 5.00%), with statistical difference (P = 0.0147 < 0.05). The development and maturation rate of revived oocytes after programmed freezing was slightly higher than that of vitrification group, but there was no statistical significance. The recovery rate (76.00% ± 2.00%) of the mouse twocell stage embryo programmed freezing group was significantly higher than that of the vitrification group (70.00% ± 2.00%), with statistical difference (P = 0.0213 < 0.05). The rate of blastocyst blastocysts in thawed embryos developed by programmed freezing was slightly lower than that of vitrification and control group, but there was no statistical significance.

Abstract:In this experiment, 20 Simmental bulls aged about 10 months and with similar body weight were selected and randomly divided into two groups, 10 bulls in each group. In the case of the same supplementary level of concentrate, feeding whole plant corn silage and yellow silage corn silage were used for comparative analysis. This provides theoretical data for feeding beef cattle with whole plant corn silage, and it will be widely promoted in beef cattle scale farms in the same area or similar areas in the future.

Abstract:The development of sheep breeding in alpine pastoral areas is largely influenced by geographical environment and feeding and management conditions. This leads to slow growth and development of sheep, low production performance, low slaughter rate, and low economic benefits. In order to explore and solve this problem, we make full use of the economic advantages of black fur Tibetan sheep to crossbreed with local Tibetan sheep. We carried out highefficiency breeding and advanced technology promotion and application of its offspring, which made the hybrid offspring of black fur Tibetan sheep become an excellent breed with large body, high limbs, strong disease resistance, fast growth, and high survival rate in alpine pastoral areas. The results show that the black fur Tibetan sheep after hybridization has good stress resistance and adaptability to the ecological environment of the alpine pastoral area, and has fast growth and high slaughter rate. On the 60th, the daily gain of growth and development of the lambs reached 191.17 g, compared with 89.67 g in the control group, and the wool yield, carcass weight, and net meat volume increased significantly (P< 0.05). This effect is very remarkable, and is favored by the local farmers and herdsmen.

Abstract:This study was to investigate the effects of compound probiotics on the growth and immune function of weaned piglets. We selected 72 Duroc × Landrace × Yorkshire weaned piglets with similar weight and good health, and randomly divided them into 3 groups. Group Ⅰ was fed with basal diet. Group Ⅱ was fed with 0.1% compound probiotics test diet. Group Ⅲ was fed with 0.1% antibiotic test diet. The pretest period was 7 days, and the formal test period was 30 days. The results showed that compared with group Ⅰ, the daily gain of group Ⅱ and group Ⅲ increased by 24.46% and 19.01% (P< 0.05), respectively, and the ratio of feed to weight decreased by 13.04% and 12.50% (P< 0.05). The serum IgG content of group Ⅱ was 34.96% and 47.80% higher than that of group Ⅰ and group Ⅲ respectively (P< 0.05). This shows that adding compound microecological preparations to the diet of weaned piglets can increase the daily gain of weaned piglets and improve the immune function of weaned piglets.

Abstract:In this experiment, mutton sheep with a body weight of about 30kg were selected.

Abstract:Guazhou County has a large area of arable land, a variety of crops, and rich straw resources. However, straws such as cotton, flowers, and sunflowers with large planting areas have relatively low prices, and no one buys and stores them. This causes most of them to be discarded or burned, which not only pollutes the environment, but also causes fire hazards. In recent years, although Guazhou County has built four forage processing plants through project support and subsidies instead of subsidies. However, due to the government's followup support and lack of support, irrelevant supporting subsidy policies, the purchase funds of forage processing plants are in short supply, and farmers have insufficient awareness and purchasing power. As a result, forage processing enterprises with large investment scale and strong processing capacity are idle, so they cannot give full play to their benefits. The author puts forward countermeasures to improve the feed utilization of crop straws for peer reference through careful investigation of crop straws in the whole county.

Abstract:The purpose of this study is to accurately grasp the degree of harm and reproductive performance of plateau pikas in the natural pastures of Yushu City, Qinghai Province, understand the dynamic situation of rodent damage, carry out rodent control in time, and improve grassland productivity. This method is to conduct a comprehensive field survey and dynamic monitoring of plateau pikas in Yushu City from 2020 to 2021. The sample area is 1/15 hm2, and they are captured, dissected, observed, measured and counted. The results show that the plateau pika can only reproduce once a year in the severe cold climate of the high altitude of Yushu. 1~9 litter per litter, mostly 3~6 litters, accounting for 91% of pregnant mice, with an average litter of 3.58 litters. The weight of male mice is 158g, and the body length is 147 mm; the weight of female mice is 176g, and the body length is 150 mm. Female mice account for 52.5% of the population. There is a certain correlation between reproductive ability and population sex ratio. We measured the daily food intake of 833 cases by gastrotomy to be 77.3g, which was about 50% of their body weight. An adult mouse can eat 9.5 kg of forage grass for 4 months in the forage growing season, and the amount of forage grass consumed by 52 adult pikas is equivalent to the daily food intake of one Tibetan sheep. However, the feed intake of the plateau pika mixed population was 66.0 g per day, with large food intake, high reproductive rate and strong destructive power.

Abstract:This study aims to accurately grasp the characteristics of Sanjiangyuan Myospalax baiLeyi density, male and female ratio, body weight, body length, coat color and reproductive performance. From 2020 to 2021, we focused on field monitoring, hole capture, and anatomical observation in the Sanjiangyuan area. The results show that Myospalax baiLeyis are active all year round. The activities are manifested in different activity periods such as mating, breastfeeding, living apart to store grain, and overwintering in the nest. There are two activity peaks: April to June in spring is the breeding season, August to October in autumn is the grain storage period, and it is limited to living in the nest from November to March. The number of male mice accounted for 40.6% of the female mice. The average weight of male mice was 1715.42 g, and the body length was 313.7 mm; the average weight of female mice was 2 205.75 g, and the body length was 206.3 mm. Male mice accounted for 77.77% of the body weight of female mice. Female rats give birth to an average of 4 litters, up to 7 litters. Each zokor digs an average of about 1 ton of soil a year, and the number of mounds pushed out to the ground is 252.1 hm². The dry weight of the soil pushed to the ground alone reaches 1043.8 kg, and the grassland area covered is 22.5 hm². The daily food intake of each zokor is 90-120 g, and each zokor can eat 21 kg of fresh grass for 7 months a year, with high reproduction rate and strong destructive power.

Abstract:The purpose of this experiment is to study the effects of different fattening methods on the benefit of Tianzhu White Yak. The test results show that Tianzhu white yaks are grazed and fattened on the grassland with abundant pasture in warm season, the fattening effect is good, and the benefit is very significant. In the offseason, yaks fed in barnyards have high meat yield and good benefits. Therefore, this study suggests that farmers can graze and fatten Tianzhu white yaks in the warm season to obtain higher economic benefits. In the cold season, the breeding greenhouse is used to increase the temperature inside the house, and the yaks are fed and fattened in the house. This can not only achieve higher economic benefits, but also stagger the peak of yak marketing, adjust the time of slaughter, and relieve the pressure on pasture grazing.

Abstract:The course of general zoology is a basic professional course for biology majors. As a part of the teaching reform project, the author conducted a midterm examination of the general zoology course. In order to understand the students' usual learning attitude and learning methods, as well as some information about the midterm exam, the author conducted a survey on the students majoring in animal science in 2019 through the Star questionnaire. The results show that most students' learning methods were not particularly ideal for various reasons, and many of them had not formed a correct learning attitude and did not actively prepare for the midterm exam. This requires the leader of the college take a variety of effective measures to improve students' recognition of the major. At the same time, teachers should also strengthen the process assessment by using the Learning APP on the basis of the midterm examination to stimulate students' interest in learning.

Abstract:Linxia City relies on its geographical advantages such as being located in the transition zone of agriculture and animal husbandry, and the 1hour urban economic circle of Lanzhou. This constantly adjusts the development structure of the animal husbandry industry, and actively encourages and guides farmers to develop largescale breeding. In recent years, the shortterm offsite fattening industry of beef cattle and other grassfed livestock, mainly small and mediumscale breeding, has developed rapidly, and its economic benefits have grown steadily. However, many problems and difficulties have also appeared in the manure treatment and environmental protection work of farms. Therefore, the author combines the current situation of the local breeding industry with the actual work of manure treatment in largescale farms. This article summarizes a set of manure treatment infrastructure construction technology, which is only for the reference of the majority of farm households and peers.

Abstract:Tibetan sheep have special breed characteristics, good breeding adaptability in highaltitude and severe cold areas, and the cost of breeding is lower than other types of sheep. However, in the case of natural mating, the empty pregnancy rate is high and the reproductive rate is low. In order to overcome the unfavorable factors such as timidity, difficulty in training, and difficulty in semen collection of Tibetan sheep, we use electrical stimulation to promote the passive ejaculation of rams, which greatly reduces the difficulty of semen collection and increases the number of semen collection. In the concentrated estrus season of ewes, more than 500 ewes can be mated by individual outstanding rams. At the same time, artificial insemination is carried out by introducing drugs to induce ewes to be in estrus at the same time. This has greatly improved the reproductive performance of Tibetan sheep and accelerated the process of introducing and improving Tibetan sheep in our county. This improves the economic benefits of Tibetan sheep breeding.

Abstract:In recent years, the Tongwei County Party Committee and the county government have vigorously carried out targeted poverty alleviation and rural revitalization strategies. Under the background of developing the honeysuckle industry, Tongwei actively explored diversified varieties and opened up a new path for industrial poverty alleviation. However, due to the export of effective labor force in rural areas, some honeysuckle cannot be picked in time, resulting in a waste of resources. Also not fully utilized for its vines, vines, and leaves, so the full development and utilization of honeysuckle have never been successful. The author organically combines honeysuckle (vines, seedlings, leaves) with the current forage silage, and compares the effectiveness of plant energy conversion into animal energy to obtain a scientific ratio. This aims to promote the adjustment of the agricultural industry structure through the development of animal husbandry and increase the income of farmers.

Abstract:Alpine Merino sheep have unique adaptability to arid and cold climate conditions. They were bred at the Gansu Sheep Breeding Technology Promotion Station in Huangcheng Town, Sunan County, Gansu Province, which is located in the alpine pastoral area. This is the first nationallevel finewool sheep breed in Gansu Province. The feeding and management of Alpine Merino sheep at each stage is of great significance to its lifelong development. This directly affects the production performance and reproductive performance of sheep, especially in the management stage of Alpine Merino lambs. If the feeding management is not good at this stage, and all links are not in place, this will definitely cause greater economic losses to the majority of farmers, herdsmen and breeding enterprises. Through years of feeding and management, the author has summed up some experience and practices in the feeding and management of Alpine Merino lambs. This has achieved certain results for the reference of the majority of herdsmen and breeding enterprises.

Abstract:China's horse industry is developing rapidly, but the low breeding rate of horses has become a difficult problem in the development process.

The proportion of largescale breeding in Zhangye City is relatively large, and the foundation for establishing a diseasefree community is good. After carefully analyzing the current situation of breeding in Zhangye City and the situation of animal disease prevention and control, we put forward ideas and countermeasures for introducing support policies, strengthening publicity and guidance, and implementing control measures for the establishment of a diseasefree community for farms. This is a suggestion for our city to create a diseasefree community and a diseasefree area, to better prevent and control animal diseases, and to maintain a stronger momentum of animal husbandry income growth.

Abstract:Severe infectious diseases such as highly pathogenic avian influenza (HPAI) and Newcastle disease (ND) are serious hazards to the poultry industry, and they are diseases that need to be prevented and controlled in the poultry industry. Among them, HPAI is a compulsory immunization disease stipulated by the state. Xinzhou District of Wuhan City is a large poultry breeding area, with more than 350 largescale poultry farms and a breeding scale of nearly 11.4 million birds. This article is to understand the pass rate of highly pathogenic avian influenza and Newcastle disease immune antibodies in largescale farms in Xinzhou District, Wuhan City in 2021. The Xinzhou District Agricultural Technology Extension Service Center of Wuhan City has conducted egg sample inspections on largescale chicken farms in the area for 12 consecutive months. Using hemagglutination and hemagglutination inhibition tests, the highly pathogenic avian influenza H5 subtype and H7 subtype were detected respectively. and Newcastle disease immune antibodies. The results showed that the qualified rates of overall immune antibodies against highly pathogenic avian influenza H5 subtype, H7 subtype and Newcastle disease were 94.1%, 96.4% and 88.9%, respectively. All of these have reached the standard of not less than 70.0% for the pass rate of immune antibodies stipulated by the Ministry of Agriculture and Rural Affairs.

Abstract:In recent years, the prevention and control of animal diseases in China has achieved important results, the safety level of animalderived food has been significantly improved, and the level of public health security has been further improved. However, footandmouth disease still occurs and prevails in many regions of the world, seriously threatening the healthy development of modern animal husbandry. In order to effectively curb the occurrence and prevalence of the disease, immunization is the most effective, economical and key strategy to prevent and eliminate the disease. However, grassroots animal epidemic prevention workers occasionally have immune side effects when injecting cattle and sheep with footandmouth disease vaccines. This has caused certain economic losses to some farmers, and has also brought certain negative effects and resistance to the prevention and control of major animal diseases. This paper analyzes the causes, clinical symptoms, treatment and preventive measures of the immune side effects of the footandmouth disease vaccine in cattle and sheep. This provides a reference for grassroots frontline staff engaged in animal epidemic prevention.

Abstract:In recent years, with the introduction of exotic animal diseases such as Peste des petits ruminants and African swine fever, conventional animal diseases such as anthrax and streptococcal disease have occurred from time to time, and the mixed infection of pathogens and virus mutation have made the disease complicated. The epidemics that had been eliminated or extinguished have revived again, and the prevention and control of animal epidemics has become the top priority of all tasks. By visiting township animal husbandry and veterinary stations and some farmers, the author conducts investigation, analysis, comprehensive research and judgment on the prevention and control of animal diseases in the county, and puts forward countermeasures and suggestions.

Abstract:Calf gastroenteritis is a common disease in calves. This is an inflammatory lesion of the calf's gastrointestinal mucosa and submucosal deep tissue. The disease can occur in all seasons. If the farmers are not strict with the feeding requirements and the feeding management is improper, the disease is very prone to occur. After the disease occurs, with the development of the disease, the inflammation gradually develops from the mucosal layer to the submucosa layer, muscle layer, and serosa layer, resulting in mucosal hemorrhage, edema, and even necrosis. This creates dysfunction and autotoxicity. The disease is severe and has a high mortality rate. This will bring great economic losses to farmers if the disease occurs.
