基于模糊数学评价法优化黑豆百合酸奶配方

以黑豆、百合为主要原料,以感官评定为指标,结合模糊数学综合评定方法对黑豆百合酸奶产品品质的各因素进行了分析。结果表明:影响酸奶品质的因素大小为黑豆乳白砂糖全脂奶粉百合乳;当黑豆乳添加量为70%,百合乳添加量为20%,全脂奶粉添加量为10%,白砂糖添加量为9%时,黑豆百合酸奶产品组织细腻,黏度合适,口感适宜。     

职业学校语文教学中实施中华优秀传统文化的思考

中共中央办公厅、国务院办公厅最近印发的《关于实施中华优秀传统文化传承发展工程的意见》明确提出了"推进职业院校民族文化传承与创新示范专业点建设"的要求,对于职业学校的语文而言,意味着教育教学的课程内容和教学方法都将出现相应的改变。这其中,传统典籍应该成为语文教学中传统文化教育的重要载体,传统文化的价值理念培养是传统文化教育的核心,与考核评价方式改革相结合是传统文化教育形式的关键,课堂向生活的延伸是学生真正走进传统文化甚至亲近传统文化的有效途径。

奶牛隐性乳房炎诊断新指标

随着畜牧业的发展,奶牛疾病的防治手段也在不断的改进和加强.然而隐形乳房炎是一种难以发现的奶牛疾病,一旦出现会严重影响牧场的健康发展,导致牧场的经济效益大幅度的降低.所以,明确奶牛隐性乳房炎诊断指标是必不可少的,可以通过牛乳细胞数进行判断.本文主要就奶牛隐形乳房炎诊断新指标进行了相关的阐述和分析.     

Effect of Fermented Chinese Medicine Preparation by Bacillus subtilis on Growth Performance,Biochemical Indices,Antioxidant Parameters and Ability of Anti-infection of Common Carp

The objective of this study was to evaluate of the growth performance, serum biochemical indices, liver antioxidant parameters and ability of anti-infection with Aeromonas hydrophila by adding the fermented Chinese medicine by Bacillus Subtilis to the carp fish feed, and to find out the appropriate supplemental level of fermented Chinese medicine in diets. Carp fingerling with an initial body weight of (35±0.5) g were set up to 6 experimental diets supplemented with 0 (control group), 0.1‰, 0.5‰, 1‰, 2‰ and 3‰ fermented Chinese medicine for 56 days, respectively. Each group had 30 fish and set up 3 repetitions. After the feeding trail,the fish were challenged with Aeromonas hydrophila to calculate the relative percentage survival (RPS).The results showed as follows:Supplementing fermented traditional Chinese medicine by Bacillus subtilis, the weight gain rate (WGR), specific growth rate (SGR), condition factor (CF), the activities of lysozyme (LSZ), complement 3 (C3),total protein (TP),total anti-oxidation capacity (T-AOC),total superoxide dismutase (T-SOD) and catalase (CAT) in serum of common carp were enhanced at different degrees, while the feed coefficient (FCR)and malondialdehyde (MDA) in serum were declined at different degrees.When the fermented Chinese medicine supplemental levels were 2‰ and 3‰,the effects were significant (P<0.05)(except for C3, ALP and Cr).The experimental results of the virulence of common carp infected with pathogen Aeromonas hydrophila showed that,the fermented herbal could obviously improve the ability of anti-infection, the immune protective rate of the group with 2‰, 3‰ doses of the fermented Chinese medicine could reach 77.23% and 74.63%, respectively. From what had been discussed above, the group with 2‰ and 3‰ doses of the fermented Chinese medicine had significant effect on the growth performance, serum biochemical indices, liver antioxidant parameters and Aeromonas hydrophila anti-infection ability. Considering the cost of adding fermented Chinese medicine, the recommendations for the best additive quantity was 2‰.     

Toxicology Test and Safety Evaluation of Cefquinome Sulfate Liposomes

The purpose of this study was to evaluate the safety of the cefquinome sulfate liposomes by using the acute toxicity test, local irritation test and chronic toxicity test. The results showed that the LD₅₀ of cefquinome sulfate liposomes was 639.73 mg/kg after intramuscular injection of its suspension and 95% confidence interval was 573.06 to 714.17 mg/kg. There was no significant stimulation to muscle. Subchronic toxicity test showed that the weight, haematological indexes and biochemical criterion of rabbits in variety dose had no significant difference compared with normal group (P>0.05). There was no visible pathological changes on the liver,kidney histology. According to pathological observation, the structure of liver and kidney were clear in treated and middle dose groups,but there existed disorganized hepatic cell cord in the liver and hemorrhag between glomerulopathy,tubulointerstitial and hepatic sinusoids in high dose group. All results proved that the cefquinome sulfate liposomes was safe and reliable based on the animal experiments.     

泌乳初期奶牛乳成分与血液生化指标相关性研究

通过分析泌乳初期健康、酮病和低钙血症奶牛血液生化指标及乳成分,明确相关疾病的乳成分特征,同时对泌乳初期奶牛血液生化指标与乳成分相关性进行分析,以期为牛群健康评价提供方法支持。根据血液指标选取产后7~21d荷斯坦奶牛72头,分为亚临床低钙血症试验组、酮病试验组和健康对照组,每组各24头。采集试验奶牛的血液和乳汁用于血液生化指标与乳成分相关性分析。结果显示,酮病和低钙血症引起乳蛋白和非脂乳固体水平降低,而乳中柠檬酸的含量增加。奶牛乳中柠檬酸与血清NEFA、BHBA和GLU相关性方程分别为:y=3.192x-0.802,R~2=0.363;y=4.594x-0.793,R~2=0.320;y=1.228x+0.775,R~2=0.261;其中方程中x为乳中柠檬酸的含量。结果表明,乳中柠檬酸的含量与血液NEFA呈显著正相关,可用于能量负平衡的早期诊断标示物。血中BUN及ALB的水平可用于评价乳蛋白和尿素的水平。     

矮滨菊的耐荫性研究

为了研究矮滨菊的耐荫性,进行了30%、50%、70%、90%4个梯度的遮荫处理,以全光照处理作为对照,观察矮滨菊在4种处理下的形态指标、光合指标的变化。结果表明:矮滨菊在遮荫度为30%时形态的数值都要明显高于其他3个处理时的数值,50%时光合的数值要明显高于其他3个处理。因此认为矮滨菊具有一定的适应弱光环境的能力,在遮荫度为30%~50%的环境下生长良好。
