含氨基酸水溶性肥料在葡萄上的肥效试验初报

为了验证含氨基酸水溶性肥料"甲壳素钾"冲施肥在葡萄上应用的实际效果,进行了肥效小区试验。结果表明:施用该肥料增产效果明显,产投比为7:1,折合平均667m~2葡萄鲜果比对照增产201.5 kg,增产率为14.4%,达到极显著水平;对提高果粒重和改善果实外观色泽有较大的作用,但对果实可溶性固形物含量和成熟度没有作用。该含氨基酸水溶性肥料对提高葡萄产量和改善品质的作用明显,可进一步开展示范性试验,为大面积应用与推广提供科学依据。

Effects of Supplemental Complex Water Soluble Vitamin on Production Performance,Blood Biochemical Parameters and Oxidation Resistance of Dairy Cows

The objective of the study was to investigate the effects of supplemental complex water soluble vitamins on production performance, blood biochemical parameters and oxidative resistance of dairy cows in spring and summer.The experiment was designed by 2×2 factorial randomized blocks design.Eighty healthy dairy cows with similar parity and body weight were randomly divided to four groups, with 7 days of adaptation and 70 d experimental phase.The dairy cows in group Ⅲ and Ⅳ were fed a basal diet supplemented with complex water soluble vitamins in spring.The dairy cows in group Ⅱ and Ⅳ were fed a basal diet supplemented with complex water soluble vitamins in summer.The results showed that the ADFI and daily milk yield of dairy cows receiving water soluble vitamin in spring were extremely significantly higher (P<0.01);The ADFI of dairy cows receiving water soluble vitamin was significantly higher in summer (P<0.05) and daily milk yield were extremely significantly higher (P<0.01);The butterfat rate was extremely significantly increased and SCC was extremely significantly decreased in spring and summer (P<0.01);Supplementation of water soluble vitamin was also significantly increased LYM (P<0.05).In summer, T-AOC, T-SOD were extremely significantly increased (P<0.01), and TP, CK, LDH, TP, HDL and ALB were extremely significantly decreased (P<0.01) by water soluble vitamin supplementation than that of control group.In conclusion, complex water soluble vitamins could increase the production performance and non-specific immune function, improve the oxidative resistance and relieved the heat stress of the dairy cows.     

小麦HMW-GS与戊聚糖含量及其组分的相关分析和聚类分析

分析了21个不同小麦品种的HMW_GS组成,并测定了各品种戊聚糖及其组分的含量。根据亚基评分对不同小麦品种HMW_GS等位基因位点变异和亚基组合类型与戊聚糖、各组分和组分比值进行了相关分析,又根据评分和总戊聚糖含量对这21个品种进行了聚类。结果表明,供试材料的HMW_GS组合类型有11余种;不同品种间,阿拉伯糖变异大,木糖变异小,戊聚糖含量和各组分均有较大差异;大部分指标与Glu_1位点有显著的负相关,其中Glu_D1位点大于另外2个位点;N,7,17 18和2 12亚基对戊聚糖及各组分含量影响较大,烘烤品质较好的亚基1和5 10对戊聚糖及各组分含量的贡献则较小;含有亚基组合(N,7,2 12)的大部分戊聚糖指标含量均较高;聚类分析中把这些品种分为4类,第1类可以作为饲料生产,第3类可以作为食品工业生产。     

家禽用药时间有讲究

维生素类。有两类:一是水溶性维生素,如维生素B类,维生素C类;二是脂溶性维生素,如维生素A、D、E、K等。作为饲料添加剂主要是复合维生素或多种维生素,随配随用效果最好。夏季维生素B和维生素E最易损失,要及时补充。抗菌素类。氯霉素、土霉素、红霉素等可混饲或混水,应按规定的时间投服,不宜长期放在水中或料中。宜注射的抗菌素,口服效果不好,如青霉素、链霉素、庆大霉素等。驱虫药类。驱蠕虫药如左旋咪唑、抗蠕敏等,肉鸡在30日龄左右,蛋鸡在60日龄和120日龄左右内服一次。宜在下午投服,第二天上午清除粪便垫料,消毒鸡舍。抗球虫药应从10…
