奶牛健康监测与评价

牛奶的安全问题与奶牛的健康息息相关,只有健康的奶牛才能生产出健康的牛奶.牛群健康管理需要随时观察、定时检测,做到“未病先防”.因此,建立奶牛健康预警系统尤其重要,通过对单个敏感指标（乳体细胞数、牛乳pH、电导率、直肠温度、产奶量等）的变化和行为学观察及体况评分、运动评分、健康指数可以及时发现亚健康牛,减少疾病造成的损失,确保原料奶的品质安全.     

One or Two Feeders for Groups of 16 Growing–Finishing Pigs: Effects on Health and Production

Over a 3-year period, seven batches of growing-finishing pigs in groups of 16 pigs (total 672 pigs) were fed using one or two singlespace feeders. The pigs with access to two feeders had a significantly lower number of skin lesions (P<0.0001) and higher daily weight gain than did the pigs with access to one feeder (863 vs. 837 g day- 1 , P<0.05). The within-pen variation in daily weight gain was higher in the pens with one feeder than in the pens with two feeders (SD 139 vs. 106g day- 1 , P<0.0001). The pigs with access to two feeders consumed more feed during the period when they were allowed to eat ad libitum , in comparison to the pigs with access to one feeder (2.07 vs. 1.97 kg day- 1 , P<0.05). The feed conversion ratio of the pigs did not differ between the two treatments. No differences in carcass meat percentage, health or number of remarks at slaughter were detected. A comparison was made between using computerized IVOG® feeders, with individual recording of feed intake, and conventional feeders. The feed conversion ratio was poorer for the pigs fed with the IVOG-feeders than for those fed with conventional feeders. The automatic recordings from the IVOG-system showed that there had been a higher daily feed intake during the ad libitum period. During the restricted period the pigs had a lower daily weight gain than with the conventional feeders.     

Dual potential of microalgae as a sustainable biofuel feedstock and animal feed

The rise in global population has led to explorations of alternative sources of energy and food. Because corn and soybean are staple food crops for humans, their common use as the main source of dietary energy and protein for food-producing animals directly competes with their allocation for human consumption. Alternatively, de-fatted marine microalgal biomass generated from the potential biofuel production may be a viable replacement of corn and soybean meal due to their high levels of protein, relatively well-balanced amino acid profiles, and rich contents of minerals and vitamins, along with unique bioactive compounds. Although the full-fatted (intact) microalgae represent the main source of omega-3 (n-3) polyunsaturated fatty acids including docohexaenoic acid (DHA) and eicosapentaenoic acid (EPA), the de-fatted microalgal biomass may still contain good amounts of these components for enriching DHA/EPA in eggs, meats, and milk. This review is written to highlight the necessity and potential of using the de-fatted microalgal biomass as a new generation of animal feed in helping address the global energy, food, and environmental issues. Nutritional feasibility and limitation of the biomass as the new feed ingredient for simple-stomached species are elaborated. Potential applications of the biomass for generating value-added animal products are also explored.

中医院校教职工对医养结合养老模式认知情况的调查与思考

目的 了解中医院校教职工对医养结合养老模式的认可程度和需求,探索促进医养结合养老模式发展的途径。方法 对湖南省某中医药大学及附属医院教职工进行问卷调查。结果 共收回有效问卷340份,在选择养老院时,被调查对象偏重于选择社区卫生服务中心内设养老机构,了解医养结合的途径主要是网络与电视,对医养结合的养老模式比较认可,但是存在认知度不高、对收费标准不满意等问题。结论 医养结合机构需要加强宣传力度;政府发挥宏观调控职能;调动社会力量积极性、增加医养结合供给;医养结合机构提高医疗和养老服务的能力和水平;加强专业人才队伍建设,发挥中医药在养老服务中的作用。
