动物福利离你还有多远?

<正>动物福利是指动物如何适应其所处的环境,满足其基本的自然需求。科学证明,如果动物健康、感觉舒适、营养充足、安全、能够自由表达天性并且不受痛苦、恐惧和压力威胁,则满足动物福利的要求。世界动物卫生组织尤其强调农场动物的福利,指出农场动物是供人吃的,但在成     

养猪人,今年你过得还好吗?

正编者按:曾经"陈欧体"突然走红,网上出现了各类神改编。"我是学生,我为自己代言"、"我是单身,我为自己代言"……网友们在发挥想象力的同时,玩了一把自嘲式的幽默。某日在一个养猪论坛里闲逛,忽然看到了"我是养猪人,我为自己代言"的帖子,脚步停了下来,打开帖子——我是养猪人,我为自己代言你只看到我卖猪时的笑容,却没有看见我的汗水;你有你的规则,我有我的选择;你否定我的存在,我决定我的未来;你嘲笑我一无所有,我总是可怜的一如既往;你可以轻视我们的简陋,我们会向你证明这是谁的时代。     

你尝试过这三种创新赢利模式吗?

正第一种,小批量产品群赢利模式创新在市场上,当主导产品赢利才能降落,成为竞争对手攻打的靶子时,什么样的产品可能冲破这种瓶颈?那就是小批量产品。而且,对小批量品牌特点药或殊效药,经销商要敢于加价、敢于赢利。在规模经济时代,营销界形成了一种     

老客户离你而去的四个理由

正一、竞争者可以轻易替代你这种问题只出现在你的产品或者服务能够被轻易复制的情况下。例如,你的业务是向大企业销售打印纸,但是他们找到了另一个供应商,能够用更低价格为他们提供所需的商品。为了避免这种问题,你需要提供个性化的,而不是标准化的产品和服务。不断地提高个性化的"档次",竞争对手就不会那么容易替代你。     

你的数据准确吗?

一般来说,在改进工序的过程中最费时间的工作就是收集数据。收集数据的目的是要验证我们的看法(即提出的“原因”)是否符合实际情形。我们对工序进行测量从而得到各种数据,然后我们就按照原先提出的问题(即根据前面所说提出的“原因”)来解释这些数据。根据这些数据,我们就可否决或确认我们原来的看法。这以后就可以根据我们了解到的情况采取行动来改进工序。因为我们要根据从数据中了解到的情况来从事改进工序的工作,所以我们就要确保我们收集到的数据可靠无误。这在你看来也许非常可笑,但我可以向你保证,这一点也不可笑。我们收集到的大部分数据都有一些固有的弱点。我们对这些弱点了解得愈透彻,我们就愈能稳操胜券。比如,让我们来看一看测量体重的情形。我们通过自己的操作来称取物体的重量,并且确信测得的重量     

你理解犬的吠叫吗?

犬交流的方式有:面部表情、吠叫、肢体语言、气味语言等。吠叫是表达方式相对单一的交流方式,但其表达的内容却很丰富。从声音特征上分析犬的吠叫吠叫作为犬的一种声音语言,具备声音所有的三个基本特征:音调、音长、频率(声音的重复率)。     

你的爱犬怀孕了吗?

爱犬在妊娠后都会表现出一系列的变化,包括行为变化、生理变化、激素变化等。作为一般的养犬者来说,并不具备作生理生化检测和仪器检查的条件,这里我们只从犬妊娠期的行为、外部形态特征、食欲变化等比较容易观察判断的方面来探讨母犬的妊娠征兆。

饲料效率和猪抗应激能力之间的关系,你关注过吗?

<正>美国爱荷华州立大学正在进行的一项研究集中于选育低剩余采食量品种的猪。10代后,已清晰地表明这些品种猪的优点除更好的饲料效率外,还表现出更好的抗应激能力。饲料是养猪生产中一项很大的成本,因此,改善饲料效率可以提高生产者的利润。另外,改善饲料效率还可支持行业竞争力,降低全球饲料资源需求,促进环境的可持续性发展。     

你的市场为啥销量上不去?

A survey of manure management on pig farms in Northern Vietnam

Animal manure can provide nutrients for crop and fish production and input for biogas production but, if managed inappropriately, can also have a negative impact on the environment. The objective of this survey was to provide information about pig production and manure management practices in the Northern part of Vietnam in order to identify and prioritize research needs for future improvements in pig manure management. A survey was conducted by in-depth interviews on 54 pig farms in two Northern Vietnamese provinces, Thai Binh and Bac Giang. In addition to the survey, also key informant responses were obtained in the two provinces to help identify problems with existing manure management. The survey showed that large-scale pig producers (> 100 fatteners or 20 sows) had more pigs per hectare than medium-scale (19–99 fatteners, 5–19 sows) or small-scale (< 19 fatteners, < 5 sows) producers. Biogas was produced from 43% of the total manure produced on all surveyed farms, and was used for cooking. The proportion of total manure applied to crops was only 5% in Thai Binh and 35% in Bac Giang. Large-scale producers tended to operate smaller fishponds, and medium-scale farms operated larger ones. The farmers were of the opinion that fish in ponds fertilized with pig manure grew significantly faster than did fish in ponds supplied with other feed or types of fertilizer. Twenty percent of pig producers reported that they raised pigs just to provide manure to feed their pond fish. A large proportion (19%) of the total manure produced was discharged into public sewage systems, rivers and lakes. Of the 54 householders interviewed, 46 believed that animal manure caused serious damage to the environment. Farmers interviewed had little or no expertise in handling liquid manure, composting solid manure, or reducing contamination by means of microbial reduction of pollutants during manure management. In general, specialized pig production is seen as a commercial operation, while manure management remains non-commercial. The survey implied that more information to farmers, as well as stronger regulation of manure management, is needed in Vietnam.     

A longitudinal study to identify constraints to dairy cattle health and production in rural smallholder communities in Northern Vietnam

The objective of the study was to investigate constraints to dairy cattle health and production in rural smallholder communities in northern Vietnam, one of the target areas of the Vietnam government's dairy development programme. A total of 99 dairy farms (11 per commune) were recruited from 9 of 32 communes in Ba Vi District, using random two-stage cluster sampling. After the initial questionnaire interviews were conducted, farms were visited at three monthly intervals over a period of 1 year. Information on several health and production parameters relating to the study cattle was collected. Using multiple indicator modelling, it was found that Fasciola infestation, farmers who had been involved in dairying for longer (not indicative of better management skills), larger herd size, and cattle being kept in a shed were linked to reduced reproductive performances.     

Temporal dynamics of dairy health and production in rural smallholder communities in Northern Vietnam

The objective of this field study was to describe the temporal pattern of dairy cattle health and production and associated risk factors in rural smallholder communities in northern Vietnam, one of the target areas of the government's dairy development programme. A total of 99 dairy farms (11 per commune) were recruited from 9 of 32 communes in Ba Vi District, Ha Tay Province, using random two-stage cluster sampling. All dairy cattle present on the selected farms were included. After the initial questionnaire survey was conducted, farms were visited to collect follow-up information at 3-monthly intervals over a period of one year. The results suggest that offtake as well as mortality are important productivity indices because farmers sell or slaughter dairy cattle that are in poor health at low prices during summer months. Changes in relation to the farming operation suggest that for the farmers adopting dairy production it has become one of the main agricultural activities.

Surveillance of swine influenza viruses in sentinel familial farms in Hung Yen province in Northern Vietnam in 2013–2014

From May 2013 to April 2014, 15 swine family‐run farms (17 pig litters) in two districts in Hung Yen province, near Hanoi, were virologically and epizootiologically monitored for swine influenza viruses (SIV) monthly. No SIV was isolated from nasal swabs. Maternal antibodies were detected in 10 litters, and seroconversion against SIV was detected in six litters. There was a marked difference in patterns of SIV transmission in the two districts. Van Lam district which has low density of swine with mainly smallholder farms had low intensity of SIV, with much of the infection caused by H1N1 2009 pandemic‐like viruses A(H1N1)pdm09, likely originated from humans. In contrast, Van Giang district, which has high swine density and larger farms, had high levels of typical SIV (triple reassortants H3N2 and H3N2 Binh Duong lineage viruses) circulating within swine. With one exception, the SIV lineages detected were those we concurrently isolated from studies in a large central abattoir in Hanoi. Influenza‐like illness symptoms reported by farmers were poorly correlated with serological evidence of SIV infection.     

北美冰川湾冰川时代的巨型幽蓝长城

在美国阿拉斯加州的东南端与加拿大接壤处,耸立着众多挺拔险峻的高峰——整个北美洲最高的10座高峰就有6座屹立在这里.终年积雪的众多山峰环抱着—个海湾,并为它挡住了来自太平洋的温暖的季风,使得该海湾降雪量极高,形成了冰川纵横、白雪盖顶的自然奇景,因此,这个海湾也被命名为冰川湾.冰川湾拥有18条冰川以及除南北极外最大的冰原,但由于全球气候变暖,在它被发现的200多年中,各条冰川均以每年数百米的速度不停地消融、后退.曾经被冰川覆盖的土地慢慢地显露出来,迅速地长满了各种植物,甚至变成了森林,吸引了众多飞禽走兽前来栖息,恢复了冰川时代之前的生机.
