Abstract:To screen for the optimal meat sheep crossbreeding combinations suitable for the Wuwei,the binary and ternary crossbreeding experiments were carried out with Australian white sheep,Suffolk sheep and Dorper sheep as male parent and Hu sheep as female parent.The results show that:(1)The birth weight of F₁ generation from Australian white×Hu sheep,Dolper×Hu sheep,Suffolk×Hu sheep,Australian white×Dolper×Hu sheep and Suffolk×Dolper×Hu sheep group was significantly higher than that of Hu sheep group(P＜0.05),the body weight of F₁ generation at 1 month and 3 month of age were significantly higher than those of Hu sheep group (P＜0.01),and the body weight of F₃ generation at 6 months old from Australian white×Hu sheep,Dolper×Hu sheep,Australian white×Dolper×Hu sheep,Suffolk×Dolper×Hu sheep was significantly higher compared with Hu sheep group (P＜0.01).The Suffolk×Hu sheep group was significantly higher than Hu sheep group(P＜0.05).(2)The pre-slaughter weight,carcass weight and net meat weight of F₁ offspring from Australian white×Hu sheep,Dolper×Hu sheep,Australian white×Dolper×Hu sheep and Suffolk×Dolper×Hu sheep were significantly higher than those of the Hu sheep group(P＜0.01).The pre-slaughter weight,carcass weight,and net meat weight of Suffolk×Hu sheep were significantly higher than those of the Hu sheep group(P<0.05).The slaughter rate of all five crossbreeding combinations was significantly higher than that of the Hu sheep group(P<0.05),and the net meat ratio,meat-to-bone ratio,and eye muscle area were significantly higher(P<0.01).(3)The marbling of F₁ offspring from Australian white×Hu sheep,Australian white×Dolper×Hu sheep and Suffolk×Dolper×Hu sheep were significantly higher than those of the Hu sheep group(P<0.05).The drip loss of Australian white×Dolper×Hu sheep and Suffolk×Dolper×Hu sheep was significantly lower than that of the other groups(P<0.05),and the cooked meat yield was significantly higher than that of the other groups(P<0.05).The results of crossbreeding experiments with Australian white ram,Duper ram,Suffolk ram and Hu sheep are obvious,and can be vigorously promoted in regions with similar ecological conditions.

Abstract:The low nutrient content of soil in desert ecosystems,combined with harsh climatic conditions,causes plants to develop unique physiological and ecological traits under environmental stress,forming the basis for the diversity and stability of desert ecosystems.However,the relationship between soil and plant biomass allocation in the Qaidam Basin and its role in maintaining desert grassland ecosystem stability remains unclear.This study analyzed the distribution characteristics of soil particle size and plant species diversity along the aridity gradient in 35 sampling sites with 175 quadrats and 86 dominant plant species in the Qaidam Basin,using methods such as plant species reordering,allometric growth relationships,variance decomposition,and structural equation modeling.It also investigated the relationship between soil nutrients and aboveground and belowground biomass of plants,and their effects on ecosystem stability.The results showed that:(1)Species richness across the 35 sites in the Qaidam Basin displays distinct environmental gradient characteristics.Perennial dominant species have significantly higher aboveground biomass compared to annual species(P<0.01),indicating that the allometric growth relationships between aboveground and belowground biomass of perennial shrubs and semishrubs are not significant(P=0.885),whereas annual dominant species allocate more biomass belowground than aboveground.(2)Stepwise regression identified seven climatic factors affecting the distribution of dominant species,and their influence on the aboveground biomass of perennial shrubs and semi-shrubs(variance decomposition R²=0.318 for aboveground biomass) was greater than their influence on belowground biomass(R²=0.01 for belowground biomass).Elevation had no significant direct effect on aboveground or belowground biomass,but the structural equation model demonstrated that elevation indirectly affects the biomass of dominant species.This indicates that altitudedriven changes in water and heat conditions,along with extreme climate events(such as isothermality,precipitation in the coldest season,and precipitation in the wettest month and season),have significant positive and negative impacts on biomass,while soil particle size has no significant effect.

Abstract:The purpose of this experiment is to explore the application of yak dry grass period house feeding technology in Banma county.Through 6-month house feeding of 3-year-old male yaks and 3-year-old yaksthe average weight gain per yak was 74.83 kg and 106.31 kg,respectively.The weight gain effect of the yaks group in experiment Ⅱ was much greater than that of the male yaks group in experiment Ⅰ.Excluding feeding costs,the weight gain benefit of yaks was 195.13 yuan/head,and that of yaks was -528.91 yuan/head,with yaks earning 724.04 yuan/head more than yaks.The results showed that under the same feeding and management conditions during the cold season and dry season,the feed return of yaks was much higher than that of male yaks,and yaks were more conducive to staggered feeding,fattening,and slaughter.

Abstract:Fowlpox is an acute and highly contagious disease caused by the fowlpox virus.The disease manifests in several clinical forms,including cutaneous,mucosal,and mixed types.The cutaneous type is characterized by the appearance of acne-like lesions on the head,comb,wattles,and featherless or less-feathered areas under the wings,which progress to scabs and eventually shed.The mucosal type is marked by necrotizing inflammation of the oral and pharyngeal mucosa,forming of pseudomembranes.Although the mortality rate of fowlpox is generally low,the disease can significantly affect infected chickens by slowing growth,reducing egg production,and lowering hatchability.Secondary infections with other pathogens and poor feeding conditions,including malnutrition,can exacerbate the disease,potentially leading to large-scale mortality.Immunization is the primary method for preventing and controlling fowlpox.However,large-scale outbreaks have continued in recent years.Analysis of clinical cases indicates that poor feeding environments are a major contributing factor to these outbreaks.Therefore,to enhance disease prevention and control,it is essential to strengthen feeding management,conduct regular environmental disinfection,maintain proper ventilation,and strengthen the overall health and immunity of the chickens.

Abstract:With the increasing number of households engaged in large-scale captive feeding of dairy goats,the occurrence of latent mastitis in the herds is constantly increasing,seriously endangering the health of the dairy goats,resulting in decreased in milk production and declined in the economic benefits of farmers.The author combines clinical breeding experience and grassroots practice,adopts traditional detection methods such as bacterial culture and CMT for diagnosis and testing,and proposes preventive and control measures:(1)Preventing and treating the incidence of latent mastitis through nipple medicated baths before and after milking.(2)For dairy goats with hidden mastitis,antibiotics should be used for timely treatment after milking.(3)By drinking and applying traditional Chinese medicine internally and externally,deworming during the dry milk period can improve the immune function of dairy goats.Thereby reducing the occurrence and harm of mastitis in dairy goats,increasing the economic benefits of breeding,and providing reference and guidance for the high-quality development of the dairy goat industry.
