Abstract:
This study aimed to evaluate the effects of different dilution media(containing egg yolk,soy lecithin,glycerol,etc.)on semen parameters of breeding rams after 6 day storage at 4 ℃.The objective was to provide scientific evidence for the low temperature delayed preservation of fresh semen from breeding rams and improve the utilization rate of high quality breeding rams.Semen samples were mixed to eliminate individual differences,and the mixed semen was evenly divided into three portions and diluted with three different dilution media(Tris base solution+soy lecithin, Tris base solution+egg yolk,milk+fructose)at an isothermal condition to achieve a final sperm concentration of 40×106/mL.Subsequently,the diluted semen was dispensed into 0.25 mL straws,sealed with polyvinyl alcohol,and stored in a constant temperature refrigerator at 4 ℃.At 0,72,120 and 144 h after storage,sperm motility parameters were determined using a computer-assisted sperm analysis system(CASA),and sperm acrosome integrity and abnormality rates were assessed using eosin staining.The results showed that sperm motility was similar in all groups at the initial state,and no abnormalities were detected.However,with the extension of storage time,sperm motility gradually decreased,and the abnormality rate gradually increased.Particularly after 144 h of storage,the milk+fructose group exhibited the lowest sperm motility and the highest abnormality rate.In contrast,the Tris base solution+soy lecithin group showed better maintenance of sperm motility in the short term,with a relatively low sperm abnormality rate.Therefore,this study indicates that selecting the appropriate dilution media is crucial for maintaining sperm motility and reducing the abnormality rate during lowtemperature preservation of semen from breeding rams at 4 ℃.Among them,the Tris base solution+soy lecithin dilution media demonstrated good application potential.

Investigation on the Biosafety Status of Swine Farms in a County of Tianshui City
Abstract:
In the absence of effective vaccines and treatment measures for African swine fever, farm biosafety is the first line of defense for the prevention and control of animal diseases such as African swine fever. In order to fully understand the biosafety status of pig farms in a county of Tianshui City, 56 biosafety evaluation indicators including 9 aspects were developed. Through online surveys and on-site visits, investigations were conducted in 76 large-scale pig farms with more than 300 pigs in stock, and discussions were held with technical guidance, business supervisors, and other departments. It was found that there were some problems in some large-scale pig farms, such as no disinfection room for goods and materials, the daily management of production areas did not flow in the specified direction, and the admission personnel did not take three-stage bathing, which were mainly related to the breeding scale of pig farms, the professional knowledge of personnel and the establishment of protection system. Corresponding suggestions were put forward, in order to provide reference for comprehensively improving the biosafety protection ability of large-scale pig farms.

Abstract:
In this study, two groups of 60 neonatal Euler ewe lambs with similar initial body conditions were subjected to different rearing methods. And the primary phenotypic traits, including 18-month body weight and body dimensions were analyzed and compared. The results indicate that the experimental group exhibited continuous growth from birth to 18 months of age. Compared to the control group, at weaning, 6 months, 12 months, and 18 months of age, the experimental group displayed significant increases in body weight, with the highly statistically significant differences (P<0.01) of 5.15 kg, 5.58 kg, 6.31 kg, and 6.86 kg, respectively. The average body height and length increased by 15 cm, 2.24 cm, 2.16 cm, 2.37 cm and 2.68 cm, 3.17 cm, 3.41 cm, 4.16 cm, respectively, both with the highly significant differences (P<0.01). The average chest circumference increased by 1.63 cm, 2.72 cm, 3.78 cm, and 4.43 cm, except at weaning where the difference was significant (P<0.05), and highly significant(P<0.01) at 6 months, 12 months, and 18 months of age. Chest depth and chest width indicators also showed significant increase, with differences (P<0.05) of 1.12 cm, 1.27 cm, 1.35 cm, 1.29 cm, and 1.84 cm, 1.60 cm, 1.10 cm, 1.89 cm, respectively. Additionally, daily weight gain, weaning survival rate, and one year survival rate were significantly higher in the experimental group compared to the control group, with highly statistically differences (P<0.01). The production performance of the experimental group met the standards of the " Euler Sheep" DB62/T490 breed for special class and first class sheep, with high breeding value and significant breeding effects, while the control group only reached the third class sheep of that. And such difference suggesting that the "grazing & timely supplementary feeding" rearing approach is a more rational method for the production of Tibetan breeding sheep in high altitude pastoral areas.

This study,based on whole genome sequencing data,used 406 horses from 76 horse breeds worldwide as the research subjects.Three sophisticated methodologies principal component analysis,phylogenetic tree,and ancestral component analysis,were used to comprehensively assess the genetic structure of modern horses at the genetic level.Additionally,genetic diversity of modern horse populations was evaluated using nucleotide diversity as an indicator,and the Fst and XP EHH selection methods were applied to detect genomic selection signals between different horse populations.Five candidate genes(HBB,EPAS1,TMEM247,RHOQ and ATP6V1E2) significantly related to the high altitude adaptation of Tibetan horses,three candidate genes (HMGA2,TBX3 and TBX5) significantly related to body size traits of Chinese Southwest horses,and genes (IGFBP3,IGFBP1,THSD7A,ADCY1) significantly related to the equestrian performances,behavior,and movements of highly selected horses in Europe and America were selected.This study provides a scientific basis for further protecting the germplasm resources of local horse breeds and reveals the selection direction of artificially cultivated horse breeds.

Abstract:
To study the optimal combination of artificially cultivated high quality forages for the feeding of An??galiba calves in confinement,40 An??galiba calves of 10 months old with similar weight,height,body length,chest girth,and cannon bone circumference were randomly selected for the experiment.The calves in experimental groups Ⅰ,Ⅱ,and Ⅲ were fed using a tethered feeding method,while group Ⅳ was grazed with supplementary feeding.Different combinations of wrapped silage forages were fed for 90 days.group Ⅰ(70% oat grass,20% red bean grass,10% sorghum hybrid sudangrass) gained 44.08 kg;group Ⅱ(60% oat grass,40% red bean grass) gained 26.59 kg;group Ⅲ(60% oat grass,40% sorghum hybrid sudangrass) gained 24.06 kg;group Ⅳ gained -13.48 kg.The economic benefits were 1 667.5 yuan for group Ⅰ,810.5 yuan for group Ⅱ,706.5 yuan for group Ⅲ,and -813.5 yuan for group Ⅳ.The results showed that the best quality coarse fodder combination was more beneficial to the growth and development of Angus cross cattle in cold season compared with grazing and supplementary feeding group.
