作者 李济宸 李群 《科学种养》 2008年第7期42-42,共1页
青贮饮料适口性好、营养丰富、消化率高,是饲喂牛羊的好饲料。制作好的青贮饮料若与大量空气接触,在微生物的作用下,就会继续进行好氧发酵并产生热量,使青贮饲料腐败,这就是青贮饲料的二次发酵,又称好气性腐败。

Problem about adolescent drinking has accelerated. Although the alcohol advertisements are restricted by Thai law, nevertheless the alcohol manufactures could still find their way to convey the message about their products to their consumers, including the adolescents in the school system through several marketing communication tactics. To this study, investigated opinion of Thai teens on alcohol use specific to.. (1) types of alcoholic beverages preferred; (2) reason at first alcohol use; (3) future drinking intention; and (4) perceptions toward alcohol marketing communication. The cross-sectional survey was conducted on 5184 students from grades 4th-12th and vocational school in seven regions of Thailand. The data from questionnaires were analyzed using simple descriptive statistic, frequency distribution, and percentages. Those teens reported to start drinking beer because of wanting to experiment with alcohol (41.3%), to celebrate in special occasion (29.2%), and due to friends involved (15.7%). Majority of teens in this study (〉 80%) disagree or strongly disagree with persuasive message of alcohol advertised through several media channels. Most of the samples have good media literacy, know the intention of the marketing communication of the alcohol manufacturers, and could not be persuaded easily. The results required further evaluation for influence of alcohol marketing communication on students' alcohol expectancy and alcohol use for proper policy recommendation and management. 展开更多

Sugar beet tops including leaves and crown harvested and chopped into 3-6 cm, mixed with sugar cane pulp and sugar cane molasses (about 5% of the total mass) to provide a mixture contained 30-35 percent dry mater. After two months of ensiling, the silage was evaluated and used in the ration of lactating buffaloes. A Latin square experiment in a changeover design, with three periods of time, each with 20 days for adaptation and 10 days for recording data, was conducted in which 15 multiparous lactating buffloes were used in three similar groups, each with five animals. The prepared silage was included in the diet of lactating buffaloes where a control diet (A) was compared with treatment diets contained 25% (B) and 50% (C) silage (DM basis) respectively. Milk yield was recorded, sampled and analysed for fat, protein, solid not-fat and total solids-content. The maximum daily rough milk yield per animal was obtained on diet C while minimum on diet A (P 〈 0.05). Similar trends were observed for 4% fat corrected milk, and 3.5% fat corrected milk that were significantly different between the treatments (P 〈 0.05). The percentage of crude fat and daily fat yield per animal were significantly (P 〈 0.05) higher in treatment C comparing to A and B. An increasingly trend of milk and fat yield was observed when the animals received silage contained diets but statistically it was significant only for the diets contained 50% silage. In addition, the fat percentage was significantly (P 〈 0.05) increased when the buffaloes received diet containing 50% silage. The highest (P 〈 0.05) amount of protein and total solid yield obtained, when the animals received high (50%) silage diet. 展开更多
