The contents of calcium （Ca） and phosphorus （P） in premix feed directly affected the growth, development and health status of shrimp. Traditional chemical analysis methods required complicated pre-treatment process for shrimp premix feed and always took several hours to obtain test results. In this study, a simple and fast analysis method, energy dispersive X-ray fluorescence spectrometry （ED-XRF）, was used to assess the contents of Ca and P in shrimp premix feed, and the test results of the samples were obtained within a few minutes. The pre-treatment process of ED-XRF method only included comminution and squash. The limit of detection of ED-XRF method for Ca and P were 43 mg/kg and 163 mg/kg, respectively, and the limit of quantification of that for Ca and P were 142 mg/kg and 544 mg/kg, respectively. Six consecutive determinations of shrimp premix feed sample 3^# were conducted by ED-XRF method. The range of the continuous measurement data of Ca and P were 0.159% and 0.013%, respectively, which were smaller than the repeatability critical difference of CrR₉₅ （6） for the contents detection of Ca （0.239%） and P （0.031%） in the recommended national standard, indicating that the ED-XRF method met the requirements of the recommended national standard for the determination of Ca and P contents in feed. By analyzing the contents of Ca and P of ten shrimp premix feed samples which were measured by national standard methods, we found that the relative differences in measured value of Ca and P contents between ED-XRF method and recommended national standard method did not exceeded 4.55%. To sum up, the ED-XRF method had high precision and accuracy, and it could be used in monitoring the addition of Ca and P for shrimp premix feed production enterprises.

This study aimed to understand and master the pollution status of fumonisins （B₁+B₂）, ochratoxin A, T-2 toxin and aflatoxin B₁ in plant feed raw materials, guide and help feed production enterprises as well as livestock and poultry breeding enterprises to carry out the prevention and control of mycotoxins pollution, avoid the harms brought by mycotoxins to feed products as well as livestock and poultry feeding, and reduce the economic losses. In the year of 2019, a total of 62 samples from 17 kinds of plant feed raw materials were collected and tested by LC-MS/MS and IAC-HPLC according to the national standard of ′Feed Hygiene Standard′ （GB 13078-2017）. The results showed that the pollution status of fumonisins （B₁+B₂）, ochratoxin A and aflatoxin B₁ in the 17 kinds of plant feed raw materials obviously varied, the average detection rates of fumonisins （B₁+B₂）, ochratoxin A and aflatoxin B₁ were 37.09%, 8.06% and 29.03%, respectively, and their maximum detection values were 15.96 mg/kg, 26.60 μg/kg and 351.00 μg/kg, respectively. According to the test results, the pollution status caused by these 4 kinds of mycotoxins in the 17 kinds of plant feed raw materials was relatively heavy, and the overall pollution rate was 48.40%. The content of aflatoxin B₁ in corn bran, spouting corn bran and peanut meal exceeded the limits required by the national standard, but the pollution rate was not proportional to the exceeding standard rate. It is indicated that the mycotoxins pollution in plant feed raw materials is widespread, which results in serious impacts to feed products and feeding safety. In view of this problem, specific suggestions on controlling the quality of plant feed raw materials were put forward, in hoping to provide reference for controlling the contents of mycotoxins in feed raw materials.

[Objective] To assess the effect of adding lactic acid in drinking water on the growth performance and disease resistance of Sanhuang chickens. [Method] A total of 5 000 one-day-old Sanhuang chickens were selected and randomly divided into 5 groups with 1 000 chickens in each group. Lactic acid was added in drinking water of the four experimental groups of A, B, C and D to adjust the pH value to 2.0, 3.0, 4.0 and 5.0, respectively. The chickens in the experimental groups were given acidified water for 4 hours per day, and the control group received normal drinking water. The body weight and feed intake of the chickens were measured, the number of dead and diseased chickens per day was recorded, and the indicators such as average daily gain, feed conversion rate and mortality rate were calculated. [Result] （1） From 1 to 35 days of age, the group C had the most obviously increase in average daily gain which was elevated by 3.33%; after 36 days of age, the group B had the similar level in average daily gain with the control group, while the other experimental groups were reduced. （2）The feed intake and feed conversion rate of the groups B and C had significant （P<0.05） differences compared with the control group, and no significant （P>0.05） differences in those between the groups A and D were observed. （3）The mortality rate of the groups A, B, C and D was reduced by 3.7%, 4.2%, 4.7% and 2.1% compared with the control group, respectively. [Conclusion] In the feeding experiment, the feed conversion rate of the Sanhuang chickens is effectively improved when the pH value of drinking water is adjusted to 4.0 by adding lactic acid. Furthermore, the average daily gain of Sanhuang chickens aged 1 to 35 days is obviously increased, and the mortality rate is obviously reduced. It is indicated that adding appropriate level of lactic acid in drinking water has good application prospects in terms of improving growth performance and disease resistance in broilers.

The elucidation of fat synthesis mechanisms and related regulative process is meaningful for preventing and curing a variety of obesity-associated diseases, ameliorating meat flavor and quality, and improving livestock production efficiency. Adipocytes originate from pluripotent mesenchymal stem cells （MSCs） in bone marrow. After receiving extracellular stimulating factors, they quickly induce the expression of early fat regulatory factors, C/EBPβ and C/EBPδ, and transmit information to PPARγ, C/EBPα and other transcription factors that promote cells differentiation and lipid droplets formation. There are varieties of transcription factors and cyclins involved in the process of differentiation of pre-adipocytes to adipocytes and adipogenesis. Studies have shown that some natural organic compounds derived from plants, such as polyphenols, alkaloids, terpenes and quinones, play important regulative roles in differentiation of adipocytes and inhibition of adipogenesis. More investigations on natural products must be done before developing medicines treatment for obesity-associated diseases through suppression of lipid droplets accumulation in cells.

The objectives of this study were to verify the pleomorphic distribution of FecB gene in the ternary hybrid sheep of Germany Mutton Merino sheep×small-tailed Han sheep×fine-wool sheep, and to assess its correlation with lambing performance of the ternary hybrid sheep. German Mutton Merino sheep and the F₂ hybrid sheep produced with small-tailed Han rams and northeast fine-wool ewes were used as the male parent and female parent, respectively, to produce the ternary hybrid sheep. The KASP method was used to analyze the genotype of FecB, and its gene frequency and genotype frequency were calculated. Furthermore, the correlation of gene frequency of FecB with the lambing performance of the ternary hybrid sheep flock was assessed. FecB gene was absent in German Mutton Merino sheep. The B allele frequency of the ternary hybrid sheep was increased significantly and was in a Hardy-weinberg imbalance state, indicating that the artificial selection had a great impact on FecB gene enrichment in hybrid sheep. The rank-sum test analysis on litter size of the individuals of F₂ hybrid ewes and ternary hybrid sheep with different genotypes demonstrated the P value were all less than 0.01, and for the two sheep flocks, the average lambing rate of the individuals with ++ genotype was both lower than those with B+ and BB genotypes （P<0.05）. It is indicated that the B allele play an important role in improving lambing performance of the ternary hybrid sheep. This study provides a reference for ameliorating the lambing performance of the ternary hybrid sheep using FecB gene.

From 2012 to 2018, the degraded alpine meadow in Xiaozhongdian Town of Shangri-La City had been chosen and enclosed as test pastures. Aboveground biomass and botanical composition were observed and analyzed for both degraded and enclosed pastures. Redundancy theory, intermediate disturbance hypothesis and threshold value theory were used to evaluate the resistance, resilience, critical threshold and reasonable stocking capacity of the test pastures. The results showed that：（1） pastures enclosure could significantly （P<0.05） increase the aboveground biomass; due to the differences in ecological environment conditions at the test sites and basic situations of the pastures, the inter-annual fluctuation range and variations of the aboveground biomass were inconsistent, but its changing trend with enclosure duration exhibited an power function type （Y=aX^b）; （2） according to the changing trend of aboveground biomass, the resistance of the degraded alpine meadow in the test area was 250.4-518.8 g/m², the pastures resilience was 54.7-68.0 months, and the critical threshold of pastures utilization was 420.6-588.7 g/m²; （3） suitable enclosure period for degraded alpine meadow was 2 to 5 years; continuous enclosure led to redundant growth of forage; the suitable stocking capacity of pastures after 5 years of enclosure was 1.1-3.4 sheep unit/hm²; after 7 years of continuous enclosure, non-feedable plants （including poisonous and harmful plants） in the pastures still accounted for 15.3% to 65.8%, and the suitable stocking capacity was low; （4） enclosure should be combined with measures such as weeds removing to reduce the redundancy of grass community components and to improve the stocking capacity of pastures.
