A total of 20 Kunming mice at the age of 20 days were divided into four groups randomly.The mice in different group were respectively fed with water containing 0,50,100 and 150 mg/L sodium fluoride for 120 d.The lesions of testicular tissue induced by fluoride were verified using paraffin-tissue sections.The results showed that fluoride had great effects on testicular tissue,which were as follows：the wall of convoluted tubule was disrupt,the structure of that was disordered;sperm cells and secondary spermatocytes were shed from seminaferous epithelium;vacuolated changes were found from cytoplasm and nucli of spermatocytes;cellular micronuclei frequency was higher;and deformity sperms were also found.

Cryopreservation of goat ooeytes is important for embryo technology. The cryopreservation development of goat follicular oocytes and preantral follicles were summarized, which would provide reference for the further researches.

The occurrence,migration,tissue localization and quantity changes of CD3＋,CD4＋ and CD8＋ T lymphocytes in chicken rectum were examined with the CD3,CD4,and CD8 monoclonal antibodies by immunohistochemical method.The results showed that T lymphocytes cells first appeared at 7-day-old.The quantity of T lymphocytes didn’t increase obviously at 1-4 day-old hatched,CD4＋ T lymphocytes mainly distributed in lamina propria of subcut aneous in intestinal villus,small quantity distributes in muscularis mucosae and lami-na propria mucosae at 7-day-old,CD3＋ T lymphocytes distributed in muscularis mucosae and lamina propria mucosae,small quantity of CD8＋ T lymphocytes distributed in muscularis mucosae.T lymphocytes kept increasing with the increase of age,large quantity distributes in mucous layer,and reached stable at 21-day-old.Among the three types,the number of CD4＋ cells was the most and CD8＋ were the least all the time.The results confirmed that the humoral immune function of rectum in chicken strengthened quickly after hatching,and reached the mature level at 21-day-old.

Since the 1970s,the genetic engineering technology developed quickly in the whole world.It has provided a broad development prospect for resolving agriculture and food issues.Using genetic engineering technology to improve the food is an important direction.In the present article,the applications of genetic engineering technology in food modification,nutritional quality and flavor were discussed.

In order to test the relative preference of corn gluten meal（CGM） and fish meal to Macrobrachium rosenbergii,the method of touch-the-ball was used.In this experiment,CGM had three levels of 5%,10% and 15%,and the feed with fish meal replaced with such three levels of CGM was given to the tested fish for 30 d.The results showed that there was no significant difference in palatability and growth when fish meal was replaced with 5%,10% and 15% CGM added with the dissociation amino acid,but there was worse palatability and growth when fish meal was replaced with 5%,10% and 15% CGM without the dissociation amino acid.Best palatability and good growth were found in the group fed with diet with fish meal replaced by 5% CGM that was added with the dissociation amino acid.All the results indicated that CGM can replace about 18% of fish meal protein in the diet of Macrobrachium rosenbergii,which does not affect the growth of Macrobrachium rosenbergii.

A total of 120 health rex rabbits with similar body weight and at the age of 50-60 d were randomly divided into four groups,group I（control group）,group Ⅱ、Ⅲ and IV（treatment group）.The rex rabbits in the group I were fed a common basal diet,and those in the group II,III and IV were fed diets containing 11%,22% and 33% Solidago canadensis L.,respectively.The results showed that the daily gain,feed intake and feed conversion ratio of rabbits in the treatment groups were not different from that of control group.The slaughter rate of rex rabbit in group III was higher than that in group II significantly（P0.05）.The flesh color B in group II was 14.6 better than that in the control group significantly（P0.05）.Other indicators were not significantly different between control group and the treatment groups.These indicated that the dosage of Solidago canadensis L.was 11%～33% and the best was 11%.

Inner Mongolia is a main producing region of sheep in China.The sheep industry there has been well established and shows a good development trend.However,there are still many problems in sheep industry development,which include lack of excellent mutton sheep breeds,no large-scale and standardized mutton sheep production base,processing enterprises running under their production capacity,imperfect breeding improvement programs for mutton sheep,and lack of nutritional standards for mutton sheep.This paper presents ideas and measures to solve these problems.

In China,pork takes an important part in people’s cookbook and it is really close to everyone.It is fact that the pig market fluctuates sharply which has called attention of the government and others.And people’s life has been influenced deeply.Since the information of pork market is difficult to acquire,the fluctuation is not regularly.People show less enthusiasm for feeding and their life is influenced seriously,because there are many shortages existing in supervisor and reserves management.This research will study on the reason for it and provide solutions to make pig market develop healthily and steadily.

With the rapid development of poultry industry in recent years,the problem of poultry breeding and potent disease control,nutrition and feeding technology are basically solved.In order to maximize their production capabilities of chicken and improve the level of feeding and disease control,the poultry house environment control is another important way.In the present article,we described the aim of poultry house environmental control,discussed the main achievements and prospected of present poultry house environmental control technology.
