取输卵管后林蛙残体的营养成分 总被引：1，自引：0，他引：1
林蛙是两栖纲、无尾目、蛙科的动物。中国林蛙 (Rana temporaria chensinensis) 的输卵管——哈士蟆油是强壮滋补药物,具有健脾胃,滋阴补肾、润肺生津之功效。民间也有用黑龙江林蛙(Rana amutensis) 的输卵管取代中国林蛙的输卵管。药用的哈士蟆油仅占林蛙机体的10—16％(见表1),其余84—90％的残体不入药,如何利用取药后的蛙体,早为人们所注目,东北民间即有取食残存蛙体的习惯。为了有效利用野生动物资源,充分应用取药后的下脚废料,我们分析了哈士蟆油取出后林蛙残体的营养成分。现报导如下。 相似文献

林蛙养殖业的主要产品为哈士蟆油,而哈士蟆油为雌性林蛙的输卵管干燥物,所以说雌蛙是养殖的主要对象和目的。在自然条件下,由于多年来对雌性林蛙的大量捕取以及其他不明的原因,使得林蛙雌、雄比例失调,雌蛙仅占群体中的30%左右。这样,一方面限制了蛙群的扩大速度,另一方面也破坏了生态平衡,降低了养殖效益。1雌性诱变原理在两栖类中,每个胚胎同时具备发育成雌性和雄性的潜能。哈士蟆没有异型的性染色体,动物的表型性别可以由改变个体发育的条件加以控制。因此,在林蛙个体发育前期的适当时间,可利用物理及化学的方法改变林蛙的个体发育环境,… 相似文献

家蚕蛾油对蛹虫草液体发酵培养的影响 总被引：1，自引：0，他引：1
通过对蛹虫草菌丝体干产量以及胞外高分子聚合物和胞内多糖含量的测量分析,研究了添加家蚕蛾油对蛹虫草(Cordyceps militarisL.)液体发酵培养效果的影响。添加4%雄蚕蛾油或2%雌蚕蛾油,蛹虫草菌丝体的产量分别增加76.1%和45.9%,胞外高分子聚合物含量分别增加64.2%和43.0%,均达到最大值;添加3%雄蚕蛾油或雌蚕蛾油使胞内多糖含量分别增加46.8%和47.1%,菌丝体产量分别增加145%和102%,均达到最大值。结果表明,添加一定量的家蚕蛾油对蛹虫草液体发酵培养具有促进作用,而在作用效果上,家蚕雄蛾油要优于家蚕雌蛾油。 相似文献

Using dry dog food label information, the hypothesis was tested that the risk of gastric dilatation-volvulus (GDV) increases with an increasing number of soy and cereal ingredients and a decreasing number of animal-protein ingredients among the first four ingredients. A nested case-control study was conducted with 85 GDV cases and 194 controls consuming a single brand and variety of dry food. Neither an increasing number of animal-protein ingredients (P=0.79) nor an increasing number of soy and cereal ingredients (P=0.83) among the first four ingredients significantly influenced GDV risk. An unexpected finding was that dry foods containing an oil or fat ingredient (e.g., sunflower oil, animal fat) among the first four ingredients were associated with a significant (P=0.01), 2.4-fold increased risk of GDV. These findings suggest that the feeding of dry dog foods that list oils or fats among the first four label ingredients predispose a high-risk dog to GDV. 相似文献

文章旨在探讨日粮添加不同油脂原料对肉牛生长性能、养分消化及瘤胃发酵性能的影响。试验选择平均初始体重（296±32.33）kg、带有瘤胃瘘管的肉牛48头,随机分为4组,每组4个重复,每个重复3头。对照组肉牛饲喂不含油脂的日粮,处理组肉牛分别饲喂含有5%棕榈油、亚麻油和包被脂肪的日粮。在为期10周的饲养试验后测定相关指标。结果：对照组与包被脂肪组干物质、有机物和氮摄入量及干物质、有机物表观消化率显著高于棕榈油和亚麻油组（P＜0.05）,而包被脂肪组与亚麻油组粗脂肪摄入量显著高于对照组和棕榈油组（P＜0.05）。对照组粗脂肪表观消化率较其他组分别显著降低31.94%、32.17%和33.56%（P＜0.05）,而亚麻油组中性洗涤纤维表观消化率较其他组分别显著降低18.61%、17.10%和19.68%（P＜0.05）。包被脂肪组瘤胃不饱和脂肪酸流量较对照组和棕榈油组分别显著提高152.26%和240%（P＜0.05）。对照组与包被脂肪组瘤胃氨氮浓度显著高于棕榈油组和亚麻油组（P＜0.05）。结论：包被脂肪降低了脂肪对瘤胃发酵的影响,其对瘤胃饱和脂肪酸流量的影响与亚麻油相似,但棕榈油降低了瘤胃氨氮浓度,不能有效向瘤胃提供不饱和脂肪酸。

The question addressed was whether the fatty acid composition of plasma cholesteryl esters (CEs) in cats reflects the intake of fatty acids. Diets containing either fish oil or sunflower oil were fed to six healthy, adult cats in a cross-over trial. The dry cat foods contained approximately 18.5% crude fat, of which two-third was in the form of the variable oil. Blood samples were collected at the end of each 4-week feeding period, and the fatty acid composition of plasma CEs and plasma concentrations of lipoproteins were determined. Consumption of the diet with fish oil was associated with significantly greater proportions of eicosapentaenoic acid, arachidonic acid, alpha-linolenic acid, oleic acid, palmitic acid and myristic acid in plasma CEs. The intake of fish oil instead of sunflower oil reduced the percentage of linoleic acid in CEs. The plasma concentrations of total cholesterol, high-density lipoprotein cholesterol, phospholipids and triglycerides were not affected by fish oil vs. sunflower oil feeding. 相似文献

Baladi rabbits were fed on five-similar-experimental diets, except the replacement for starch in the 1st diet, cattle tallow in the 2nd, cotton seed oil in the 3rd, and hydrogenated palm oil in the 4th instead of 2% more wheat bran in the 5th (control) diet. All other husbandry conditions were the same for all groups of animals during the experimental period of 7 weeks. The cattle tallow in the second diet caused significant increase of feed intake, growth rate, relative weights of kidneys, lungs and heart and calcium of the tibia bone. This diet had tendency to diminish significantly blood contents of total nitrogen and cholesterol as well as vitamin A in the liver and tibia contents of silica, phosphorus and magnesium. Diet number 3 included cottonseed oil lowered blood contents of glucose, phosphorus, cholesterol and enzyme activity of glutamate oxaloacetate transaminase in the serum and specific gravity of tibia bone. On the other hand, it elevated significantly (P less than or equal to 0.01) stored vitamin A in the liver than on all other experimental diets. Feeding rabbits on diet including hydrogenated palm oil subsided liver contents of dry matter, ash and vitamin A and raised ether extract of the liver significantly. It reduced also dry matter content of the femoral muscle. Substitution for starch (instead of 2% of the diet fats or bran) increased blood content of haemoglobin and haematocrit (insignificant) but values of glucose and phosphorus as well as liver content of dry matter, content of femoral muscle of dry matter and ether extract and content of tibia bone of silica and phosphorus were significantly higher than the other experimental diets. It decreased relative weights of different organs (significantly) and liver contents of ether extract and vitamin A (insignificantly) than on control diet. It could be said that the addition of cattle tallow and cottonseed oil would be recommended to be included in rabbit diets after more studies to determine the effects of the different animal-vegetable mixtures of fats, the best ratio between the two sources of fats, the interrelationships between that mixtures and the energy of the diet, the dietary protein level, the rabbit breed and their weights and aim of the production under the seasonal variation of the weather. 相似文献

本试验旨在研究热应激条件下脂肪来源对肉兔生产性能、养分消化率及血清脂质代谢和抗氧化指标的影响。试验选择30日龄的断奶新西兰兔600只,随机分成5个组,每个组6个重复,每个重复20只。对照组饲喂基础饲粮,各脂肪添加组分别饲喂含2%牛油、猪油、玉米油、豆油的饲粮。试验兔均饲养在热应激兔舍(温湿指数为29.5±0.5)中。试验期7周。结果表明:与对照组相比,热应激条件下饲粮中添加不同来源的脂肪均可以显著提高肉兔的平均日增重(P0.05),显著降低料重比(P0.05),其中以玉米油的效果最佳。与对照组相比,热应激条件下饲粮中添加不同来源的脂肪均可以显著提高肉兔的干物质和粗蛋白质消化率(P0.05),显著降低粗脂肪消化率(P0.05),但对粗灰分和粗纤维消化率无显著影响(P0.05),其中玉米油组的干物质消化率最高,豆油组的粗蛋白质消化率最高。与对照组相比,热应激条件下饲粮添加牛油或猪油可以显著提高肉兔血清甘油三酯和总胆固醇含量(P0.05);玉米油组和豆油组肉兔血清甘油三酯和总胆固醇含量则与对照组差异不显著(P0.05)。与对照组相比,热应激条件下饲粮添加豆油和玉米油可以显著提高肉兔血清超氧化物歧化酶活性和总抗氧化能力(P0.05),显著降低血清丙二醛含量(P0.05);牛油组和猪油组血清超氧化物歧化酶活性、总抗氧化能力和丙二醛含量则与对照组差异不显著(P0.05)。由此可见,热应激条件下,饲粮添加不同来源的脂肪均可提高肉兔生产性能及干物质和粗蛋白质消化率,从整体效果来看,玉米油豆油猪油牛油;饲粮添加牛油或猪油可提高肉兔血清甘油三酯和总胆固醇含量,对机体抗氧化能力的影响不显著;饲粮添加豆油或玉米油对肉兔血清甘油三酯和总胆固醇含量无显著影响,但可显著提高机体的抗氧化能力。 相似文献
