[Objectives] This study was conducted to use the feeding value of wolfberry branches and to provide a basis for the rational use of its active ingredients and nutrients and the development of new feed resources. [Methods] Wolfberry branches and whole-plant corn were used to make mixed silage of wolfberry branches, which replaced different proportions of whole-plant corn silage for feeding hybrid mutton sheep, and the feeding effect of the mixed silage of wolfberry branches on hybrid mutton sheep was analyzed, which provides a technical basis for rational utilization of mulberry resources to ruminants. A single factor feeding comparison experiment was carried out. 32 hybrid mutton sheep of 8 months old with conform gender, age, body weight, physiological state and feeding management level were selected and divided into two groups, 16 in each group. [Results] The gross output value of weight gain of the experimental group was 18.06 yuan, which was higher than the CK(12.97 yuan) by 5.09 yuan. [Conclusions] The addition of the mixed silage of wolfberry branches to the diet had a positive effect on the increase of the weight gain of the hybrid mutton sheep and the reduction of the feed conversion ratio compared with the single whole-plant corn silage.

[Objectives]This study was conducted to explore and rationally use the effective value and nutritional components of wolfberry polysaccharide to provide a basis for the use of new feed resources.[Methods]The premixed feed prepared with the wolfberry polysaccharide additive was applied to fattening Tan sheep in Ningxia,and the effect of the wolfberry polysaccharide additive on the fattening Tan sheep was analyzed,so as to provide technical support for the rational utilization of the wolfberry polysaccharide *** study adopted a single-factor comparison method,selecting 84 tan sheep in the fattening period with conform gender,feeding management,weight,age,and physiological status,which were divided into 2 test groups and 1 control group,28 in each group.[Results]Within 90 d,the weight gain of the group with 0.1%wolfberry polysaccharide additive increased by 6.98%,showing a significant difference(P<0.05),and the feed conversion ratio decreased by 9.66%,which was significant as well(P<0.05).The gross profit of this group was 125.76 yuan,which was higher than the control group by 57.52 *** group with 0.2%wolfberry polysaccharide additive increased the weight gain by 8.63%,which was significant(P<0.05),and the feed conversion ratio decreased by 10.80%,which was significant as well(P<0.05).The gross profit of group 2 was 125.76 yuan,which was higher than the control group by 63.41 *** were no significant differences in weight gain,feed conversion ratio and gross profit between the groups with 0.1%and 0.2%of wolfberry polysaccharide *** results showed that the use of wolfberry polysaccharide additive premixed feed has a positive effect on increasing the weight gain of fattening Tan sheep,reducing the feed conversion ratio,and improving the feed conversion *** addition of 0.1%and 0.2%of the wolfberry polysaccharide additive premixed feed had no significant differences.[Conclusions]The wolfberry polysaccharide additive has a positive e

[Objectives]This study was conducted to investigate the appropriate addition amounts of lactic acid bacteria and cellulase in the mixed silage of potato plants,so as to provide a basis for the rational use of potato plants.[Methods]Fresh potato(Solanum tuberosum)seedling plants,watermelon(Citrullus lanatus)plants,and melon(Cucumis melo)plants were selected as raw materials for silage,each of which was added at a ratio of 32%,and 4%of brown flour was added *** this basis,an L 9(32)orthogonal experiment was designed to investigate the effects of the amount of lactic acid bacteria(10,20,30 g/kg)and the amount of cellulase(5,10,15 g/kg)on the experimental results with sensory evaluation score as an investigation index.[Results]With the increase of the amount of lactic acid bacteria and the amount of cellulase,the sensory evaluation score of silage increased,and it was the highest when the amount of lactic acid bacteria added was 20 g/kg and the amount of cellulose was 10 g/*** the increase of the amounts of lactic acid bacteria and cellulase added,ammonia nitrogen showed a decreasing trend,and the pH and ammonia nitrogen were the lowest when the amount of lactic acid bacteria added was 20 g/kg and the amount of cellulose was 10 g/kg.[Conclusions]This study provides a theoretical basis for the rational use of effective ingredients and nutrients in potato plants and the development of new feed resources.

目的探讨甲状腺功能亢进患者131碘(131I)治疗前后骨密度的变化特点及131I治疗甲状腺功能亢进的价值。方法通过对我科甲状腺功能亢进患者按照治疗前后、性别及年龄(女性绝经后及男性>50岁设定为高龄组,女性未绝经及男性≤50岁设为青年组)等因素进行分组,通过对131I治疗前[经过抗甲状腺药物(antithyroid drugs,ATD)治疗后]的骨密度及131I治疗后18个月的骨密度测定值进行分析;另选取同期健康体检者140例作为对照组。结果本组甲状腺功能亢进患者131I治疗前(ATD治疗后)的骨密度较健康对照组减低,但同组经131I治疗后各部位骨密度较治疗前明显好转(P<0.05)。131I治疗前及治疗后不同性别、不同年龄组骨密度均有差异,且治疗后女性骨密度的变化值与男性组比较差异有统计学意义,青年组骨密度的变化值与高龄组差异有统计学意义(P<0.05)。男女高龄组骨密度的变化值差异亦有统计学意义(P<0.05)。结论甲状腺功能亢进时对骨密度影响较大,与性别、年龄及ATD的使用关系密切。ATD治疗甲状腺功能亢进对骨密度的改善不显著,131I治疗后骨密度显著改善,131I治疗甲状腺功能亢进较ATD对骨密度的恢复更具优势。
