松针饲料,就是利用松科树种的针叶而加工的饲料;南方主要用马尾松针叶为原料,而北方可大力发展利用油松针叶。据研究表明：松针中含有维生素Ｃ、胡萝卜素、硫胺素、核黄素、粗蛋白质、粗脂肪、粗纤维、无氮浸出物、灰分以及糖类、氨基酸等物质。从而提高了饲料利用率,改善饲料品质,促进畜禽生长,可提高增重、产蛋率和产奶率,节省了饲料,增强了对疾病的抗病防病能力。据报道,在产蛋鸡饲料中加５％松针粉,可提高产蛋率１３．８％,并可使蛋黄色泽变深。在猪的饲料中加３．５％松针粉,其增重提高可达１５％,饲养周期可缩短６０天,… 相似文献

松针系指松树的针叶,又称松毛,它包括马尾松、黑松、油松、赤松、红松、落叶松、樟子松、云杉、冷杉等树的叶子。松针作为饲料,在我国的应用历史并不长,所以,在这种特定的情况下,把它叫做新的饲料,又由于松针在吉林省,乃至朝鲜族自治州境内,资源丰富,储藏量极大,难以用数字衡量,过去又没有对松针加以合理利用,有待于开发利用, 相似文献

<正>1概述松树主要有赤松、红松、油松、黑松、马尾松、高山松、云南松、华山松、黄松和樟子松等,特别是马尾松在我国分布较广,资源极为丰富。松针粉是将从松树上修剪下来的幼嫩枝条和针叶收集起来,经过干燥、粉碎而成的。松针粉色绿、幽香,是良好的家兔饲料添加剂。在家兔日粮中添加松针粉可明显促进家兔生长,提高产毛量,增加母兔产仔数和提高仔兔成活率,提高幼兔生长速度,可使兔毛皮普遍光泽度好。同时,松针粉或鲜针叶还含有植物杀菌素,具有防病抗病之功效。 相似文献

松针(马尾松、黄山松、黑松、赤松、云南松、油松、樟子松、湿地松、落叶松、红松、云杉、冷杉等树叶)是林业部门进行松林抚育和采伐后,残留的大量枝梢、针叶等剩余物,若任其腐烂或焚烧,不仅浪费森林资源,又易引起森林火灾或招致病虫害,有损于森林。近几年来,我国林业科学研究部门,为了合理利用森林资源,变废为宝,将松针进行多品种多功能化学分析,并加工成新的林业化工产品——饲料添加剂,这对开辟新的饲料来源,解决饲料严重不足具有十分重要意义。松针粉富含多种氨基酸、蛋白质、脂肪、微量元素,植物杀菌素和多种维生素等,含有畜禽需要的各种营养成分达40多种,其中,特 相似文献

松针维生素粉外观为草绿色,具有针叶固有的气味,呈粉末状。由于松针维生素粉中含有植物杀菌素、蛋白质、维生素、氨基酸、微量元素等多种营养物质,所以它是一种营养价值较好的畜禽补充饲料。松针维生素粉的原料主要来源于松林抚育和采伐时丢弃在林地上的枝丫、梢头、嫩枝、绿叶等废料。松针维生素粉补充饲料,我国从1979年开始 相似文献

松针粉质量的优劣取决于胡萝卜素含量的高低,而胡萝卜素含量的高低又取决于松针粉加工方法的先进与否。根据松针粉加工新工艺研究的试验结果,新鲜的松针叶,不论任何一个品种,其胡萝卜素的含量均可达到200mg/kg以上,有些品种还可达到300mg/kg以上。松针叶自采摘以后受阳光、空气、温度的影响,其针叶细胞内的氧化酶、过氧化酶因自动氧化的作用而使针叶发生褐变,同时也使针叶细胞内胡萝卜素的含量迅速下降,只有在控制贮存器内的含氧量为0.5％～1.5％,含水量5％～7％时,对胡萝卜素的保存才最为有利。 国内有关单位研究的或生产用的… 相似文献

In late December 1985, 1485 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1985 and 44% of them responded. Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献
