2022年是实施"十四五"规划承上启下之年,是乡村振兴全面展开的关键之年,广西各级农业农村部门认真贯彻落实自治区党委政府决策部署,坚持稳中求进的工作总基调,落实高质量发展要求,统筹推进疫情防控和畜牧业经济发展,上半年生猪稳产保供成效显著,牛羊产业稳中向好,禽蛋产业稳定发展.

做好畜禽遗传资源保护与利用工作是维护生物多样性、促进现代畜牧业可持续发展的重要手段.广西畜禽遗传资源丰富,拥有地方畜禽品种37个,其中陆川猪、巴马香猪、环江香猪(与贵州的从江香猪并称为"香猪")、龙胜凤鸡、德保矮马共5个品种被列入了《国家级畜禽遗传资源保护名录》.2019年,广西多措并举,扎实推进畜禽遗传资源保护工作,有效促进了区域优质畜禽遗传资源的开发利用.

广西地方畜禽品种资源丰富,是我国种质资源集中地之一,但部分地区对地方品种资源的保护意识薄弱,亟需加强.本文主要对七百弄山羊的品种来源及发展、 外貌特征、生产性能、 饲养管理等作了详细介绍.

七百弄鸡是广西大化瑶族自治县农村群众自繁自养而形成的一个地方品种,为促进地方畜禽遗传资源的保护和开发利用,本文对七百弄鸡的品种来源、 饲养管理、 产品品质特色、 疫病防控等作了详细介绍.

2016年,在持续推进"美丽广西·清洁乡村"和"美丽广西·生态乡村"基础上,广西大力升级乡村建设,在农村施行改圈工程,对农村"楼上住人楼下养畜"的人畜混居现象进行治理,采用财政奖补方式,对畜圈进行改造.通过在住房外建设独立圈舍,完善粪污处理设施,解决恶臭、蚊蝇、环境污染等问题,提高农民群众居住舒适度,达到宜居乡村的目的.本文简单介绍改圈工程的必要性及存在问题,并提出建议和措施.

畜牧业是现代农业的重要组成部分,其健康可持续发展,对保障国民经济生活水平,促进农业产业结构优化升级,具有重要的意义.畜牧业由于生产周期长,资金投入大,且受市场需求、自然灾害和疾病风险影响较大,要实现产业化、现代化、跨越式发展,离不开金融保险行业的支持.国家也越来越重视金融在农业方面的应用,2017年"中央一号文件"就提出:探索建立农产品收入保险制度.支持符合条件的涉农企业上市融资、发行债券、兼并重组.

[Objective] In this study,blood routine examination indexes of Guike pigs were detected,number variation and morphology distribution of different functional cells (red blood cells,white cells and platelets) were researched to provide basic reference data for Guike pig immunological evaluation and disease resistance research.[Method] Fortyfour healthy Guike pigs had been taken blood samples each week since 49 days old and lasted for seven weeks.Their blood routine examination indexes were measured,and compared with those of Landrace pigs and Enshi black pig.[Result] In red blood cells indexes of Guike pigs of different day ages,red blood cells (RBC) number and hemoglobin (HGB) content were the lowest(6.85× 1012/L and 97.1 g/L) at the age of 70 days,significantly lower than the corresponding value at 49,56,63,84 and 91days old (P＜0.05,the same below).The rhythms of mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were basically the same,both were the lowest (15.11 PG and 275.70 g/L) at the age of 70 days,and reached the highest value(16.40 pg and 314.30 g/L) at the age of 91 days.Hematokrit(HCT),mean corpuscular volume(MCV) and red blood cell distribution width(RDW) changed stablely,and there was no significant difference between different ages (P＞0.05,the same below).In white blood cells indexes,the total number of white blood cells (WBC) at the age of 63 days was the lowest (13.71 × 109/L),reached the highest value (17.52 × 109/L)at the age of 84 days,there was significant difference between them.Neutrophils (NEUT) reached the the lowest(3.61 × 109/L) at the age of 70 days,significantly lower than the corresponding value of 49 and 56 days old.The change of total lymphocyte count (LYMPH) was relatively stable,it was not significantly affected by the increase of age.In platelet indexes,platelet (PLT) count,plateletcrit (PCT) and platelet distribution width (PDW) were relatively stable at different ages,and they were not significantly influenced by age.Compared with the 35 days old Landrace pigs and 5 months old Enshi black pigs,most of the blood routine indexes of Guike pigs were in between normal blood routine index values of Landrace pigs and enshi black pigs except for a few indexes:HCT,mean platelet volume (MPV),PCT and DW.[Conclusion]Guike pigs are peculiar in blood routine examination indexes.The pigs at 49-91 days old develop stable immune system.
