The influence of boron with different level added in water on renal organization structure was studied. 180 pcs of 1 d old Gushi chicks were randomly divided into control group, Group Ⅰ and Ⅱ, the drinking water of Group Ⅰ and Ⅱ contained 100 and 200 mg/L boron resp., the experiment period was 6 w. 10 pcs of Gushi chickens were selected at every weekend to slaughter by bloodletting at neck artery and vein, kidney were taken at once in anatomy, fixed with Bouin liquid, paraffin section prepared, H .E staining, microscopic observation and photograph were conducted. The results showed that glomus swelling on renal corpuscle, tubular wall cell swelling of renal tubule, degeneration, denaturalization of collecting tubule and on the straight part cell particles of renal tubule for tested Group Ⅰ at 1-2 w; the renal organization structure began to restore from the 3rd week and organization structure got right at the 6th week. For the Group Ⅱ, at 1-2 w, the phenomena of atrophy, necrosis and disintegration of renal corpuscle glomus for Gushi chickens were common, capsule of glomerulus became bigger, capsule wall structure was not complete, swelling of proximal and distal convoluted tubular cells, denaturalization or hydropic degeneration of cell particles; the renal organization structure of Gushi chickens had recovery sign at 3-6 w; but the renal histopathology change was still evident at the 6th week. Conclusion： There were some inhibitory or damage effects on renal organization structure of Gushi chickens at 1 -2 w by adding 100 mg/L boron in drinking water, and had promotion and improvement effects on renal organization structure growth of chickens at 3 -6 w.It had inhibitory even toxic effect on renal organization structure growth of Gushi chickens by adding 200 mg/L boron in water at the whole test period, so as to affect body excretion function.

The protection of baicalin on the acute liver injury in mice was discussed. Fifty mice were divided into 5 groups of the control, model, low, moderate and high baicalin doses randomly. The baicalin groups were given different doses of baicalin injection by subcutaneous injection and the acute liver injury was induced by carbon tetraehloride in mice, then the feed intake, drinking amount, liver index, activities of ALT in serum and liver and the content of TP, ALB and GLO of mice were observed. The results indicated that compared with model group, the activities of ALT in mice serum of all the close groups of baicalin were decreased extremely significantly （P〈0.01）, that in mice liver were increased extremely significantly （P〈0.01）and their other indices had no significant difference. It was concluded that the baicalin given by subcutaneous injection had some protection on the liver injury induced by carbon tetrachloride in mice and the moderate dose was best.

According to 4×4 latin square design, four 2.5-3 years old Simmnental steers with average body weight of （420±20） kg and equipped with permanent ruminal cannulas were selected in the experiment. With DL-met-Cu as Cu source and mixed concentrates and air dried corn stalks as basal diet, the effects of adding Cu on different levels （0, 8, 16 and 24 mg/kg dry matter） in diet on the nutrient digestibility of steers were studied on 1.3 M nutrition level. The results showed that the digestibility of crude fat in the group of 8 mg/kg was best and had no significant difference （P〉0.05）,the digestibility of no-nitrogen extracts in the group of 16 mg/kg was extemely significantly higher than that of the controlled group （P〈0.01）. The digestibilities of OM, CP, CF, NDF and ADF in the group of 24 mg/ kg were best, in whch the digestibility of CP was extremely significantly higher than that of the controlled group （P〈0.01）.The addition of 24 mg/kg dry Cu in diet could significantly improve the nutrient digestibility of diet. It was suggested that with DL-met-Cu as Cu source, the diet should be added with 24 mg/kg Cu.

The waste produced from soy extraction was used to feed and fatten pigs in the experiment performed by the author.

The detection limit of copper was 0.04 μg/mL, its RSD was 3.3 % and its recovery of standard addition was 97 %.This method was simple and convenient. The determination by this method was fast and precise, so it could be used in the practical determination of samples.

The effect of adding commodity phytase into the laying hens＇ feed to substitute dicalcium phosphate （DCP） with different level was explored and discussed by using the principle of phytase being able to hydrolyze phytic acid in plant feedstuffs. 50 to 54-week-old Hy-line brown laying hens were selected as experiment objects, 400 FYT phytase were added in every 1 000 kg feedstuff to replace 8 g and 16 g of DCP resp. to observe the influence of phytase on the performance of laying hens. The results showed that the performance of laying hens could keep steady by replacing 16 g DCP with 400 FYT phytase, while the performance of laying hens could be enhanced with substitution of 8 g DCP. The daily egg output, laying rate and feed-egg ratio raised 3.4 %, 3.6 % and 3.7 % resp., therefore, the performance of laying hens could be enhanced by replacing 8 g DCP with 400 FYT phytase in the laying hens＇ feed and total phosphorus in feed formula could be reduced as well.

The fresh chicken feces were collected from invesgation points of 3 locations of Liuan, Shouxian and Huoqiu by population sampling method for feces detection. The oocysts were isolated from positive feces samples by saturation salt solution float method and centrifugal sedimentation method. The oocysts were obserVed under microscope for species identification and the infection rate and intensity of chicken coccidia of all the investigation points were calculated. The results indicated that in the 50 checked fresh chicken feces samples, the infection rate of chicken coccidia was 100 %, 6 species of coccidia were detected and they were E. necatrix, E. acervulina, E. maxima, E. tenella, E. mitis and E. praecox of the genus Eimeria resp. It was illustrated that chicken coccidia was universial in west Anhui region and in some investigation points, its infection intensity was very high and the scientific control awareness of raising households was not strong.

The epidemiological investigation on PPV disease was performed among 1 520 pregnant sows of 21 intensive pig farms of 6 cities （counties） with different geographic environments of Xuancheng City in Anhui Province by the writer. Among them, the reproductive handicap syndrome occurred on 671 sows, which accounted for 44.1%.The 1 520 pregnant sows produced 7 799 piglets, among which the 1 530 piglets were dead and the dead piglets accounted for 19.6 % in the total piglets. Among 671 pregnant sows with reproductive handicap syndrome, 207 shares of serum were sampled for serologic examination on PPV, Cp, Br and JEV. Among them, the positive response of antibody to PPV was up to 79.8 %. The study results indicated that the main cause of reproductive handicap syndrome was PPV infection in the city. So, the main object of preventing reproductive handicap syndrome should be transferred from Br disease to PPV disease and the periodic monitorring system of antibody in serum of pig group should be set up to strengthen the epidemic prevention of PPV disease.
