天然DHA牛奶产品开发 《畜牧与饲料科学》2016,37(10):46-46
DHA（二十二碳六烯酸）属于ω-3多不饱和脂肪酸,对人类健康有着特殊的作用和影响,主要体现在改善记忆、促进视网膜形成及儿童脑发育等方面。主要阐述了使用经过包埋处理的微藻粉对奶牛的饲料进行DHA强化生产天然DHA原料奶的生产技术。利用该技术生产的原料奶天然含有DHA成分,不需要进行后期的添加。该原料奶具备正常原奶的加工特性,并加工各个类型产品,可以保证产品中天然含有DHA组分。 相似文献

优质乳是奶业发展的方向 总被引：1，自引：1，他引：0
发展方向决定兴衰存亡。我国奶业经历了30年的快速发展,取得了巨大成就,但是也正在面临发展新方向的抉择。这个新方向就是发展优质乳,需要明确提出"一杯优质牛奶振兴一个民族"的理念。我国有关奶业科研团队,经过近20年的艰苦探索和协同创新,已经形成了适合国情的"优质乳生产的奶牛营养调控与规范化饲养技术"成果并示范应用,示范结果表明,在奶牛生产中使蛋白质饲料利用效率提高8%~15%,乳脂率和乳蛋白率分别达到3.5%和3.1%,牛奶体细胞数低于40万个,细菌总数低于10万CFU/mL,完全达到国际上优质乳的营养品质和卫生安全水平。如何从国家政策的战略设计上进一步明确优质乳的发展方向,积极组织推广优质乳科技成果,大力发展和弘扬优质、健康、向上的奶业文化,应该引起重视。 相似文献

The introduction of specific genes into the genome of farm animals and its stable incorporation into the germ line has been a major technological advance in agriculture. Transgenic technology provides a method to rapidly introduce "new" genes into cattle, swine, sheep, and goats without crossbreeding. It is a more extreme methodology, but in essence, not really different from crossbreeding or genetic selection in its result. Methods to produce transgenic animals have been available for more than 20 yr, yet recently lines of transgenic livestock have been developed that have the potential to improve animal agriculture and benefit producers and/or consumers. There are a number of methods that can be used to produce transgenic animals. However, the primary method to date has been the microinjection of genes into the pronuclei of zygotes. This method is one of an array of rapidly developing transgenic methodologies. Another method that has enjoyed recent success is that of nuclear transfer or "cloning." The use of this technique to produce transgenic livestock will profoundly affect the use of transgenic technology in livestock production. Cell-based, nuclear transfer or cloning strategies have several distinct advantages for use in the production of transgenic livestock that cannot be attained using pronuclear injection of DNA. Practical applications of transgenesis in livestock production include enhanced prolificacy and reproductive performance, increased feed utilization and growth rate, improved carcass composition, improved milk production and/or composition, and increased disease resistance. One practical application of transgenics in swine production is to improve milk production and/or composition. To address the problem of low milk production, transgenic swine over-expressing the milk protein bovine alpha-lactalbumin were developed and characterized. The outcomes assessed were milk composition, milk yield, and piglet growth. Our results indicate that transgenic overexpression of milk proteins may provide a means to improve swine lactation performance. 相似文献

Factors influencing adoption of milk cooling technology were studied with data for 90 smallholder dairy farmers who were randomly selected from seven dairy cooperative societies in Kiambu County, Kenya. Logistic regression identified the age of the household head, daily household milk consumption, freehold land ownership, fodder production area, number of female calves, cooperative membership and cooperative services as significant factors influencing farmers’ willingness to invest in milk cooling technology. These findings offer an entry point for increased interventions by policy makers and various dairy sector stakeholders in promoting milk cooling technology with the aim of significantly reducing post-harvest losses and increasing the sector’s competitiveness. 相似文献
