Abstract:This study comparatively analyzed the superovulation effect of Alxa white cashmere goats under grazing and indoor feeding modes. The experimental data indicated that the superovulation performance of goats in the indoor feeding mode was significantly better than that in the grazing mode. The indoor feeding group showed marked advantages in terms of average follicle-stimulating hormone (FSH) dose (150-160 IU), average estrus duration (12h after progestin withdrawal), average number of flushed embryos (12.56 per goat), average number of usable embryos (11.31 per goat), and the proportion of unusable embryos (10%), all with statistical significance (P<0.05). In contrast, the grazing group had an average FSH dose of 138-142 IU, and although their average estrus duration was shorter (4-5h after progestin withdrawal), they had lower average numbers of flushed embryos (8.56 per goat) and usable embryos (7.81 per goat), accompanied by a higher proportion of unusable embryos (16%) (P<0.05). It is worth noting that under indoor feeding conditions, the goats exhibited lower standard deviations (SD) in the number of flushed embryos (1.5) and the number of usable embryos (1.3), suggesting a smaller variability in these metrics among individuals. This contributes to the enhancement of the overall quality of embryos and the success rate of embryo transfer. In summary, the indoor feeding condition, through the creation of a stable feeding environment and refined management strategies, effectively enhances the superovulation performance of Alxa white cashmere goats, demonstrating significant advantages compared to the grazing mode. These findings not only provide important support for the sustainable development of the cashmere goat industry, but also serve as a scientific reference for future improvements in feeding management and breeding techniques.

Abstract:This study focused on the impact of different breeding modes (indoor feeding vs.outdoor feeding) on the efficiency of supernumerary ovulation in Alxa white cashmere goats.By strictly controlling non-breeding variables such as goat age (2-4 years),weight,health status,and reproductive stage,we ensure consistency and reliability of the experimental data.We use a randomized group assignment strategy to divide the experimental animals into an indoor feeding group (40 animals) and a outdoor feeding group (30 animals),and provide uniform nutrition,health monitoring,and standardized supernumerary ovulation procedures to minimize external factor interference.The results showed that the average FSH dose was suitable (150-160 IU),the average estrus time was stable (12 h after suppositing),and the average embryo recovery and the number of available embryos were significantly higher than those in the free-range group (12.56 vs 8.56 vs 12.56,respectively).(11.31 vs 7.81) and a low proportion of unusable embryos (10% vs 16%) (P<0.05).This study confirmed that by providing stable feeding conditions and refined management strategies,the house feeding environment significantly enhanced the superplatoon efficiency of Alxa white cashmere goats,showing obvious advantages over grazing mode.These research results not only laid the theoretical foundation for the sustainable development of cashmere goat farming industry,but also provided practical guidance to lead the industry in the future.They highlight the significant advantages of the house feeding mode in improving the efficiency of overdischarge,and inspire a new direction of fine feeding management,scientific nutrition regulation and reproductive technology innovation.These findings have inspired in-depth exploration and optimization of the breeding environment,nutritional formulations and breeding strategies to comprehensively improve the production performance of cashmere goats and promote the breeding industry towards an efficient,environmentally friendly and sustainable future.

Abstract:This study was designed to explore the potential benefits of alginate oligosaccharides as a feed additive in largescale broiler farming.Despite the fact that alginate oligosaccharides have been confirmed to possess immunomodulatory functions,there is currently a dearth of research on their direct application in the drinking water of broilers on a largescale farm.To bridge this gap,starting from April 2023,alginate oligosaccharides powder was added to the drinking water system in a broiler farm in this experiment,and the weight gain and mortality and culling of broilers were recorded.The results indicated that there was a 0.22 kg difference in the average market weight of broilers between the alginate oligosaccharides group and the control group,and the difference in mortality and culling was highly significant(P<0.001).Additionally,the economic benefits of alginate oligosaccharides as a feed additive were further substantiated through cost accounting.These findings not only furnish a scientific basis for the application of alginate oligosaccharides in broiler farming but also offer a new reference for farmers in the selection of feed additives.

Abstract:The experiment was conducted to investigate the effects of different treatment groups on growth performance, immune function and blood biochemical indexes of lambs. Thirty-six healthy Hu sheep lambs with similar body weight were randomly divided into control group (basal diet), trial group Ⅰ(70% basal diet +30% alfalfa meal) and trial groupⅡ (70% basal diet +30% alfalfa meal +1% probiotics). The experiment lasted for 60 days. The results showed as follows: there were no significant differences in final weight, dry matter intake and ratio of feed to gain among all groups (P > 0.05), and the average daily gain in test groupⅡ was 10.40% higher than that in control group (P <0.05), but no significant difference between test groupⅠ and control group (P > 0.05). Aspartate aminotransferase and alkaline phosphatase in trial groupⅡ were significantly lower than those in control group (P <0.05), triglycerides in trial groupsⅠ and Ⅱ were significantly lower than those in control group (P <0.05); The IgG content of test group Ⅱ was significantly higher than that of the other two groups (P <0.05), but the IgA and IgM contents were not significantly different among groups (P > 0.05). Therefore, dietary supplementation with probiotics + forage fiber can improve growth performance of lambs, improve some serum biochemical indexes, enhance the immune function and body resistance of lambs.

Abstract:To establish an effective supplementary feeding time for grazing Tibetan sheep,two groups of Tibetan sheep with similar nutritional levels and the same grazing methods were supplemented with the same amount of feed at different time periods from October 2,2022 to December 30,2022(experiment 1) and from January 1,2023 to March 31,2023(experiment 2).From the analysis of the weight gain effect,the average total weight gain during the entire period of experiment 1 was 4.50 kg,which was 0.6 kg more than the average total weight gain of 3.9 kg during experiment 2.The supplementary feeding effect was better.From the analysis of the benefits of supplementary feeding,experiment 1 increased the income by 57.15 yuan per animal,while experiment 2 increased the income by 58.65 yuan per animal.The supplementary feeding benefits of experiment 1 were slightly lower than those of experiment 2,but there was no significant difference.From the perspective of ecological benefits analysis,by combining moderate grazing on warm season grasslands with semi captive feeding and fattening in cold season,it is possible to achieve the slaughter of Tibetan sheep at the age of 12 months,which can reduce the pressure on cold season grasslands,promote changes in the production and operation mode of grassland animal husbandry,and make the Gannan pastoral area ecologically sound,productive,prosperous,and socially harmonious.Based on the comprehensive economic and ecological benefits,it can be concluded that timely supplementation of grazing Tibetan sheep is an effective way for the transformation and development of grassland animal husbandry in highaltitude pastoral areas from “relying on the nature” to “scientific animal husbandry”,and to improve the quality and efficiency of the industry.experiment 1(supplementary feeding period from October to December)is the period during which the maximum benefit of supplementary feeding and fattening is achieved for 12-month-old Tibetan sheep.

Abstract:To determine the optimal supplementary feeding time for grazing Tibetan sheep, feeding experiments were conducted during two different periods: from October 1, 2022, to December 31, 2022 (Experiment 1), and from January 1, 2023, to March 31, 2023 (Experiment 2). The results of Experiment 1 showed that the experimental group of sheep gained a total weight of 4.50 kg over the 90-day trial period, with an average daily gain of 50 g, while the control group had a total weight loss of -3.12 kg, with an average daily loss of -34.4 g. The difference was highly significant (P < 0.01). Experiment 2 revealed that the experimental group of sheep gained a total weight of 3.9 kg over the 90-day trial period, with an average daily gain of 43.33 g, whereas the control group had a total weight loss of-3.59

Abstract:In order to study the effects of different weaning patterns on the growth and development of Gannan calving yaks,a univariate variance design was used in this experiment.A total of 90 calving yaks with similar body weight(11.34±1.62kg)were selected as test subjects and randomly divided into 3 groups:natural range group (control group),3-month-old weaning group (experiment group 1) and 6-month-old weaning group(experiment group 2).Thirty calves were in each group,half male and half female.The experiment period was 6 months.Weight,height,length and chest circumference of calves were measured at birth,four months and seven months of age.The results show that:The growth and development of calving yaks with early weaning is better than the traditional feeding mode,which can effectively improve the growth performance of calves,and is an effective feeding mode that can be popularized.

The results showed that the in vitro release rate was ranked in the order of fast to slow: kw5 > kw1 > kw3 > kw2 > kw7 > kw8 > kw6 > kw4. It was found that kw1 had a moderate bactericidal speed,but its duration was longer,and it could still prevent bacterial resistance from developing for 72 hours. The results showed that cefquinome sulfate suspension had good antibacterial efficacy and could maintain its effect for a long time. Therefore,it is suggested for clinical application.
