    The experiment aimed to analyze the genetic diversity of Yao chicken using the sequence of mitochondrial DNA control region (D-loop region). A total of 64 Yao chicken’s mitochondrial DNA D-loop regions were fully sequenced to assess the genetic diversity and haplotype characteristics of Yao chickens. Additionally, a NJ phylogenetic tree was constructed to illustrate the relationship between different haplotypes and red jungle fowl. The results showed that the genetic diversity of haplotypes in Yao chickens were 0.779, with a nucleic acid diversity of 0.00148. Ten haplotypes were identified, belonging to four haplotype groups A, B, C, and E, with E being the dominant haplotype group. The main maternal source might be the Indian subspecies in South Asia. This study enriches the genetic diversity data of chicken populations in China and provides a scientific basis for the conservation, utilization and genetic breeding of Yao chicken germplasm resources.

    To better understand the variability and distribution of comb notches number of single-combed Qingyuan Partridge Chickens in the conservation and breeding populations, this study investigated the fast-feathering and slow-feathering lines within the conservation and breeding populations of Qingyuan Partridge Chickens. Furthermore, the study explored the differences in comb notch numbers among slow-feathering lines, as well as the correlations between comb notch numbers and body weight (at 42, 70, and 105 days of age), body measurements (comb height, tibia length, and tibia circumference) at different ages. The results indicated that the predominant comb notch numbers for various strains of Qingyuan Partridge chickens were 5 for large ones, and 5, 6, and 7 notches are the majority, among which the comb notches of male Qingyuan Partridge Chickens are all above 4. Large comb notch number and total comb notch number showed no impact or correlation with body weight and body measurements at various stages for male Qingyuan Partridge chickens. The hens with a large comb notch number ≥6 and a total comb notch number of 7 exhibited better growth performance. Among the correlations with different comb notch numbers, there was a significantly weak positive correlation between large comb notch number in slow-feathering line hens of Qingyuan Partridge chickens and body weight at 42 days of age (r=0.161,P＜0.01), indicating that the large comb notch number in single-combed Qingyuan Partridge slow-feathering line hens could assist in early selection for body weight at 42 days of age.

    The research studied the effects of Epigallocatechin gallate (EGCG) on egg quality and inflammatory factors in spleen, liver, and ileum mucosa of heat-stressed laying ducks. 180 42-week-old Linwu laying ducks were allocated into control or EGCG-treated groups. Each group had 6 replicates with 15 ducks in each replicate. The control group was fed with basal diet, while the experimental group was fed basal diet with 300 mg/kg EGCG supplemented. The pre trial period was 10 days, and the trial period was 42 days. The trial period is divided into two stages: heat stress period and recovery period, each with 21 days. Results showed that supplementing 300 mg/kg EGCG to the diet (1) significantly enhanced the eggshell strength of laying ducks during the heat stress period (P<0.05). (2) It increased the content of TNF-α in spleen during recovery period (P<0.05) , reduced the content of IL-6 in spleen during both the heat stress period (P<0.01) and the recovery period (P<0.05). There was no significant effect on the TNF-α content in the spleen during the heat stress period, nor on the levels of transforming growth factor β (TGF-β) and interleukin-1 (IL-1) throughout the entire period (P>0.05). (3) It exerted no significant effect on TGF-β, TNF-α, IL-1 and IL-6 in liver during whole period (P>0.05). (4) During the heat stress period， it significantly increased TGF-β (P<0.05) and reduced IL-6 (P<0.01) in the ileum mucosa, and significantly reduced the IL-6 content in the ileum mucosa during recovery period (P<0.05). However, there was no significant effect on the content of TNF-β during recovery period and TNF-α and IL-1 during the whole period (P>0.05). Therefore, it can be seen that adding EGCG to diet can improve egg qualities of heat-stressed ducks, reduce IL-6 in spleen and ileum mucosa of heat-stressed laying ducks, and enhance TNF-α in spleen and TGF-β in ileum mucosa.

    The study aims to investigate the methods for isolation, culture, identification, and induction of differentiation of satellite cells from rabbit skeletal muscle, and to establish a comprehensive culture system for rabbit skeletal muscle satellite cells. New Zealand White rabbits at 1 day of age were selected as the experimental animals and satellite cells from hind leg muscle tissue were isolated using a combination of collagenase and trypsin digestion method. Subsequently, the satellite cells were purified using differential adhesion method and induced into mature myotubes under low serum conditions. Finally, protein immunoblotting technique was employed to analyze the expression of the satellite cell marker gene MyoG, and the induced differentiated skeletal muscle satellite cells were identified using MHC immunofluorescence staining for myosin heavy chain (MHC). The results showed that the purified rabbit skeletal muscle satellite cells exhibited a spindle-shaped morphology with evident refringence. Upon further induction of myogenic differentiation, successful formation of myotubes was observed. Protein immunoblotting results indicated a significant increase in MyoG expression in the differentiated cells, while immunofluorescence indentification showed positivity for MHC. In conclusion, this experiment successfully isolated and cultured primary rabbit skeletal muscle satellite cells, established a comprehensive culture and induction differentiation technique system for rabbit skeletal muscle satellite cells, laying a solid foundation for further in vitro studies on rabbit skeletal muscle satellite cells.

    This study focuses on the soil-grass-livestock system in Dangxiong County, Lhasa City. Soil, grass, and yak blood samples were collected in both warm season (July) and cold season (December), which were analyzed to determine the levels of major elements and trace elements. The study aims to investigate the dynamic changes and correlations of mineral elements within the soil-grass-livestock system, and provide a scientific basis for supplementing mineral elements during the winter feeding process for yaks.The results showed that (1)there were significant differences in the contents of mineral elements in pasture soils between cold and warm-season (P<0.05). The contents of K, Na, Fe, Mn, Zn, Cu, Co and Se in warm-season pasture soils were significantly higher than those in cold-season pasture soil (P<0.05), while the contents of Ca and P in warm-season were significantly lower than those in cold season (P<0.05). (2) The contents of K, P, Fe, Zn, Co and Se of forages in warm-season were significantly higher than those of cold-season (P<0.05),  the contents of Na and Mn were significantly lower than those of cold-season pasture (P<0.05), and neither Ca nor Cu content in forage showed a significant difference between warm- and cold-season pastures (P>0.05). (3) The  P content of yak serum in July was significantly higher than that in December (P<0.05), the contents of Na and Cu of yak serum in July were significantly lower than those in December (P<0.05). However, the contents of K, Ca, Fe, Mn, Zn and Se did not show significant changes between warm and cold seasons (P>0.05). (4) In warm-season pastures, the contents of  P and Se in soils correlate significantly with those in forage (P<0.05), additionally, the contents of Ca, K, Fe and Se elements of yak serum correlate significantly with those in forages(P<0.05). In cold-season pastures, Na contents in both soils and forage showed a significant correlation (P<0.05) , and only Se content in forages and yak serum exhibited a significant correlation (P<0.05). In summary, substantial changes in mineral elements are found in pasture soils and forages between cold and warm seasons. Therefore, the variation in mineral elements due to season shifts should be taken into account in yak grazing management. It is important to supplement specific mineral elements in the forage to ensure the health of the yaks.

    To explore the passivation ability of cow dung biochar (DMB), manganese dioxide modified cow dung biochar (MDMB), and amine modified cow dung biochar (NDMB) in Pb and Cd co-contaminated soil, a soil passivation experiment was conducted using Pb and Cd co-contaminated black soil as the research object. The effects of different types and application rates (0.2%, 0.4%, 0.6%) of cow dung biochar on soil physicochemical properties, available content, speciation distribution of Pb and Cd in soil, and the enrichment and translocation of Pb and Cd by silage corn were analyzed. The results showed that the soil pH, electrical conductivity, and organic matter content increased with the application of DMB. Additionally, the biochar transformed the weak acid extractable forms of Pb and Cd into residual forms. When the application rate was 0.6%, the distribution of weak acid extractable Pb and Cd in the MDMB treatment decreased to 10.21% and 40.21%, respectively, while the residual form distribution increased to 49.23% and 23.23%, showing the most significant passivation effect on Pb and Cd in the soil. Compared to the control treatment (CK), the available content of Pb and Cd in the soil decreased by 38.53% and 49.98%, respectively. The biochar reduced the enrichment factor of Pb in the silage part (SP) and roots (RP) of silage corn, and only showed a decreasing trend in Cd in RP. Meanwhile, the translocation factor of Pb and Cd increased with the application of cow dung biochar. The research results indicated that the application of biochar changed the physicochemical properties of the soil. Modified cow dung biochar had a stronger ability to reduce the available content of Pb and Cd compared to cow dung biochar, it also reduced the enrichment of Pb and Cd by silage corn in the soil, but promoted the transfer of Pb and Cd to the silage part.

    By evaluating the consumption of residual livestock manure in crop planting area, the load-bearing capacity of manure application on cropland, and pollution threat levels, this study explores the balance and dynamics of using livestock manure as fertilizer in major agricultural regions of the Sichuan Basin (Hongya, Kaijiang, Yanting, and Xingwen Counties) from 2006 to 2017. The results indicate that over the past decade, the load-bearing capacity of livestock manure on cropland in this area has been approximately 0.84, with a pollution threat level classified as Level III (“potential pollution threat”). The cultivated areas capable of absorbing residual manure increased from 1.80×104 hm2 to 7.11×104 hm2. Meanwhile, the load levels of nitrogen, phosphorus, and manure on cropland have shown a declining trend, suggesting a slowed imbalance. Significant regional differences were observed in the degree of imbalance: Hongya County exhibited the highest load-bearing level at 1.20, classified as Level IV (“serious pollution threat”); Yanting County followed (0.90, Level III), Kaijiang (0.84, Level III), while Xingwen exhibited the lowest level at 0.53, classified as Level II (“slight pollution threat”). Phosphorus pollution posed a more prominent risk than nitrogen, with phosphorus load levels (0.84) exceeding those of nitrogen (0.63). The pollution threat grade for phosphorus was Level III, higher than that for nitrogen (Level II). The findings suggest that tailored crop-livestock integration models are key to achieving the balance of planting and breeding by using livestock manure as fertiliser.

    To elucidate the efficiency and influencing patterns of two technologies-wet curtain filtration and deodorization curtain spraying-on ammonia reduction, this study provides foundational research data for ammonia emission reduction in livestock housing. The primary measurement indicator is the ammonia concentration before and after purification. Utilizing a simulated experimental chamber while minimizing interference factors, the study investigates the impacts of technologies, emission concentration, circulating liquid, and their interactions on ammonia removal efficiency. The results indicate that (1) there is no significant difference in ammonia removal efficiency between the two processes (P>0.05); both methods achieve removal efficiencies exceeding 30%. (2) Emission concentration and circulating liquid significantly affect ammonia removal efficiency (P<0.05), with both the emission concentration and the pH of the circulating liquid showing a negative correlation with ammonia removal. (3) The interactions between the three factors-technologies, emission concentration, and circulating liquid-do not show a significant impact on ammonia removal efficiency, nor do the pairwise interactions among these factors (P>0.05). In summary, processes based on chemical absorption can effectively reduce ammonia emissions in livestock housing while ensuring production safety and controlling economic costs. Furthermore, efficiency can be improved by adjusting the pH of the circulating liquid, thereby providing a theoretical basis and data support for ammonia reduction strategies in livestock environments.

    Drug residues in livestock and poultry products not only affect the safety of livestock products, but also endanger human health, product export trade and social stability. Countries around the world are intensifying their efforts to manage drug residues. The Chinese government attaches great importance on the regulation of drug residues in livestock and poultry products, and the safety level of these products is currently at its historical peak. However, drug residues in livestock and poultry products have not yet been eradicated. This paper proposes comprehensive measures for controlling drug residues throughout the entire production process of livestock produts, aiming to promote the green, low-carbon, and high-quality development of animal husbandry in China.

    Food waste and distiller's grains are important local wastes that can be converted into high-quality protein by the black soldier fly (Hermetia illucens). The ratio of food waste to distiller's grains is 10∶0 in the control group (A),While it is 9∶1,8∶2,7.5∶2.5 and 7∶3 in group B,C,D and E,respectively. The results showed that (1) at the age of 26 days, the proportion of distiller's grains was 10%, and there was a significant difference in the quality of black soldier flies compared to other treatment groups (P<0.05). (2) When the proportion of distiller's grains was 10%, the weight of black soldier fly  was the highest, at 241.80 mg/20 pieces. When the proportion of distiller's grains  was 30%, the minimum weight gain  was 165.89 mg/20 pieces. (3) When the proportion of distiller's grains exceeded 20%, the food intake of black soldier fly larvae began to decrease. Compared with the control, when the proportion of distiller's grains  was 10%, the feeding amount of black soldier fly larvae  was the highest, at 163.10 g/20 pieces. (4) When the proportion of distiller's grains  was 10%, the black soldier fly  was the longest, with an average of 2.12 cm/20 pieces. When the proportion of distiller's grains  was 30%, It  was the shortest, with an average of 1.89 cm/20 pieces. In summary, the optimal ratio of distiller's grains to kitchen waste for the growth of black soldier fly larvae is 1∶9. This study provides technical support for the future recycling of distiller's grains and kitchen waste.

    Giardia duodenalis is an important intestinal protozoan parasite that can infect a variety of hosts, including pigs and humans. It causes diarrhea, malnutrition, weight loss and other clinical manifestations, which not only brings considerable economic losses to the animal husbandry but also endangers the public health. Molecular biology techniques have played important roles in the detection, genotyping and traceability of Giardia duodenalis. The paper reviews the molecular epidemiology of Giardia duodenalis from pigs in China, providing a reference for the effective prevention and control of giardiasis.

    Under the context of developing new agricultural disciplines, education on the welfare of aquatic animals has become a key breakthrough for cultivating versatile agricultural talents in the new era. This study uses the course Aquatic Ecology as a platform for reform, systematically analyzing core issues in current teaching such as fragmented knowledge systems, lack of practical training, and insufficient interdisciplinary integration. An innovative Four-Dimensional Driving teaching reform model is constructed. Strategies including course module restructuring (theoretical advancement), integration of virtual and real scenarios (technological empowerment), interdisciplinary PBL (Problem-Based Learning) collaboration (capability integration), and a three-dimensional evaluation system (quality closed-loop) are implemented to achieve the organic unification of knowledge transmission, skill development, and value shaping. The results show that, after reform, students' mastery of aquatic animal welfare knowledge increased by 29.8% (P<0.01), the excellent rate in technological application improved by 65.2% (P<0.01), and ethical decision-making ability increased by 53.6% (P<0.05). The constructed sustainable teaching reform model of “Disciplinary Integration-Embedded Virtual and Real Scenario-Industry-education Collaboration” provides a replicable solution for curriculum innovation in aquaculture-related courses.
