The results showed that there was no significant difference in plant height (3.08 m) between applying organic fertilizer and inorganic fertilizer (P>0.05), but there was significant difference in plant height (1.52 kg) between applying organic fertilizer and inorganic fertilizer (P<0.05), the fresh grass yield (84.53 t/hm²) and hay yield (32.01 t/hm²) were the highest, which were significantly higher than that of applying chemical fertilizer and organic fertilizer (P<0.05), and the contents of DM (37.87%) and Starch (38.47%) were the highest, there was no significant difference between applying chemical fertilizer (P>0.05) and applying organic fertilizer (P<0.05). The content of NDF (33.90%) and ADF (20.90%) in forage grass with organic and inorganic fertilizer was the lowest, which was significantly different from that with chemical fertilizer and organic fertilizer (P<0.05). In conclusion, the application of organic and inorganic fertilizer can improve the yield and quality of forage maize in arid and semiarid area.

Abstract:Intestinal obstruction caused by foreign objects in small animals is one of the common intestinal diseases in dogs. It is easily confused with hemorrhagic gastroenteritis in clinical practice. This experiment, based on the medical history of a patient dog, combined with blood routine examination, CRP examination, endoscopy, and differential diagnosis with hemorrhagic gastroenteritis, determined that it was a foreign body obstruction in the dog' intestines. The patient dog was attempted to use exploratory laparotomy for treatment. After the surgery, the main treatment measures were antiinflammatory, supplementing nutrition and body fluids, and repairing the gastrointestinal mucosa, achieving significant therapeutic effects. The research results can provide a reference diagnosis and treatment plan for the differential diagnosis and treatment of intestinal foreign body obstruction and hemorrhagic gastroenteritis in pet dogs.

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.

Abstract:Weaning stress in calves refers to the process of transitioning from liquid breast milk to solid feed during weaning, which causes significant stress on the digestive system of calves. This stress reaction can affect the health and production performance of calves, which may lead to impaired growth and development, reduced feed intake, slow growth rate, dysfunction of the rumen, impaired immune function, and adverse reactions to the endocrine system of calves. Cows under weaning stress are also susceptible to other diseases, and their health level will be decreased. Relevant research shows that 17% of calves will show signs of respiratory diseases after entering the fattening environment, and reducing the occurrence of stress reaction in the early stage of calves can reduce the incidence rate of respiratory diseases in the fattening stage. Therefore, in the process of breeding, reasonable measures should be taken to alleviate the weaning stress of calves to improve their health level and production performance. This article aims to discuss the impact of weaning stress on the occurrence and spread of diseases in calves, and propose effective prevention and control strategies for this issue. By implementing these prevention and control strategies, the impact of weaning stress on calves can be effectively reduced, and the occurrence and spread of related diseases can be reduced.
