什么是一头“四事件”母牛

What is a four-event cow?

Meet cow 8968. 请看8968号母牛

She lives on an 1500-cow dairy farm in Wisconsin, where she’s milked three times per day through a double-20 parallel parlor. She’s fed a well-balanced ration, and spends her time resting in sand-bedded freestalls. She is a second lactation cow, sired by 11HO11499 AltaMEGLO, and she’s what we call a 4-event cow.

她生活在威斯康辛州的一个1500头成乳牛的牧场。每天在双-20位的并列式挤奶厅3次挤奶。她采食平衡的日粮,在散栏式牛棚沙床休息。她现在是二胎牛,父亲是011HO11499 AltaMEGLO,她就是我们称之为四事件母牛。

 A 4-event cow? 

什么是一头四事件母牛

If you look at any cow card in DairyComp or your herd management program, a 4-event cow has only four major events listed throughout her lactation:

如果你用DC-305软件或你牛群的其他管理软件查看任何母牛的卡片,一头四事件母牛在其整个泌乳期中列出的只有4个主要事件:

  1.     Fresh、

    产犊、

  2. Bred、

    配种、

  3.  Confirmed pregnant、

    确认怀孕、

  4.  Dry、

    干奶。

In the case of 8968, this means she had a live calf with no troubles. She had no milk fever, ketosis, or retained placenta. No other metabolic issues slowed her down after calving, and by avoiding those issues, she did not incur treatment costs.

在8968的例子中,这意味着她无任何麻烦地产下一头活犊牛,无产后瘫痪、酮病和胎衣不下。产后无其他使其产量下降的代谢病,通过避免了这些问题,她没有发生任何治疗费用。

After a 60-day voluntary wait period, 8698 was bred. Since BRED is only listed once on her cow card, we know it took only one unit of semen – just one insemination for her to conceive.

过了60天自愿等候期给8968号配了种。由于其母牛卡片上只列出了一次配种,我们知道只使用了一个剂量的冻精,即只配一次就怀孕了。

She was later confirmed pregnant, noted as PREG on her cow card. This is only possible because she did not have early embryonic death loss or an abortion, and no other reproductive troubles.

其后确认了她怀孕,其母牛卡片上标注为PREG。只有没发生过早期胚胎死亡损失或流产,也没有其他繁殖问题这才可能实现。

The fourth, and final event of 8968’s lactation shows as DRY on her cow card. This means there were no other lingering issues throughout her lactation. She went about her business as usual, until it was time to be dried off in preparation for her next lactation.

第四,8968号母牛卡片上的泌乳期最后标注只有DRY(干奶)。这意味着在她整个泌乳期内没有其他有关疾病的问题。她一如既往地产奶直到干奶,为下一个泌乳期做准备。

What’s missing?

缺失了什么?

You might wonder what is missing from 8968’s cow card. Of course, maintenance events like pen moves, foot trims, vaccinations, and pregnancy rechecks also occur during a cow’s lactation.

你可能想知道8968的母牛卡片上缺失了什么。当然,在一头母牛的泌乳期中还发生像调圈、修蹄、疫苗注射和再次孕检等维持事件。

But what’s really missing in a 4-event cow’s lactation are the setbacks – the costly, time-consuming issues that hinder overall herd profitability. A 4-event cow like 8968 does not get mastitis. She doesn’t become lame, and she does not abort her calf midway through the pregnancy. She avoids the sickness, infections and troubles that cause major headaches for every dairy producer.

但在一头四事件母牛的泌乳期中,真正缺少的是挫折——这是一个昂贵、耗时的问题,它阻碍了牛群的整体盈利能力。像8968这样的四事件母牛没患乳房炎,没患蹄病,也没有在怀孕中途流产。她避免了会给每个养牛人带来严重头痛的疾病、感染和麻烦

Can genetics help create a herd of four-event cows?

遗传计划有助于创造四事件母牛群体吗?

One of the best ways to create more four-event cows is to select for Productive Life (PL) within your customized genetic plan. Genetic selection for PL doesn’t just mean more old cows. It predicts which cows are toughest, healthiest and easiest to manage.

创建更多四事件母牛的最佳方法之一是在定制的遗传计划中选择生产寿命(PL)。按PL的遗传选择不只是意味着更多的老牛,它还预测哪些母牛最皮实、最健康、最容易管理。

Including Productive Life in your genetic plan will increase your odds of having a herd full of four-event cows. The actual measure of PL is not calculated until after a cow leaves the herd. However, we can use other ways to see if higher PL bulls actually create healthier and more trouble-free cows.

在你的遗传计划中包含生产寿命,就会增加你拥有整群四事件母牛的几率。实际的PL值直到母牛离群后才能计算出,但我们可以用其他方法观察PL更高的公牛是否真的创造了更健康,更多无麻烦的母牛。

Table 1 breaks down the events within the herd where cow 8968 lives. It includes all animals with known Holstein sire ID’s. Based only on each animal’s parent average for Productive Life, this shows the real difference in the health events between high PL pedigreed cows and low PL pedigrees.

表1列出了8968号母牛所在牛群的事件,它包括全部有荷斯坦父号的母牛。这个表格仅根据每头牛父母生产寿命的平均值,显示了高PL系谱母牛与低PL之间健康事件的真正差异。

These are real numbers, recorded on this farm’s herd management software program. Keep in mind, management is consistent throughout the herd, and no preferential treatment is provided for any given cow.

这些是记录在这个牛场牧群管理软件程序中的真实数字。请记住,整个牛群的管理是一致的,没有给任何特定的母牛提供特殊待遇。

The table clearly shows the high PL cows had fewer issues after calving and throughout their lactation. High PL cows had fewer aborts, were coded as ‘do not breeds’ (DNB) less often, and had fewer cases of DA’s, lameness, mastitis, and RPs. This led to fewer of the high PL cows leaving the herd involuntarily.

这个表格清楚地表明,PL高的母牛在产后和整个泌乳期的问题较少,流产次数少,编码为“禁配”(DNB)的次数少,患真胃移位、蹄病、乳房炎和胎衣不下(RPs)的病例也少。这导致PL高的母牛被动淘汰的寥寥无几。

Compare those results to 8968. Her sire, AltaMEGLO is a 6.3 for sire PL, which is a big part in her status as a 4-event cow with no issues.

将这些结果与8968号母牛比较。其父亲AltaMEGLO的PL值是6.3,毫无疑问,这是构成这头四事件母牛的重要原因。

Make more 4-event cows like 8968  创造更多像8968的四事件母牛

Cow 8968 is not only a 4-event cow. She’s a profitable cow. Consider the time and money you save, and peace of mind you gain, with 4-event cows. A herd full of cows like 8968 don’t require costly treatments, and don’t drop in milk production due to those health concerns.

母牛8968不仅是一头四事件母牛,当然还是盈利的。考虑一下你节省的时间和金钱,有了四事件母牛你可获得心灵平静。一群像8968这样的母牛不需要昂贵的治疗费用,也不会因为那些健康问题而减少产奶量。

Keep these costs – or savings – in mind as you customize your genetic plan. If healthy, trouble-free cows are your goal, genetic selection for Productive Life will help you create more of those desirable 4-event cows – just like cow 8968.

当定制你的遗传计划时,请记住这些成本或节约的成本。如果你的目标是健康、无麻烦的母牛,那么按生产寿命进行遗传选择将有助于你创造更多理想的四事件母牛—就像8968号母牛一样。
