  Pork producers who want to get the most out of every ingredient in a sow diet can look to new research showing the value of supplementing vitamins at optimal levels.

  猪肉生产商若想要最大程度地发挥母猪日粮中的每一种成分,可以关注下面的这项新研究,该研究揭示了维生素含量水平最佳的饲料的价值。

  The most recent research, supported by DSM Nutritional Products and carried out at Kansas State University, shows that an optimum level of vitamin D3 supplementation in the sow diet can measurably impact the performance of sows and their progeny.

  由DSM赞助,在堪萨斯州立大学进行的最新研究表明,若母猪饲料中含最佳水平的维生素D3,可显著影响母猪及其后代的生产性能。

  Additionally, the research shows a higher level of vitamin D3 supplementation doesn’t always support more benefits. For some criteria, the sows and their progeny performed best when the sows were fed an “optimum” rather than a high level of vitamin D3.

  此外,研究还显示供应高水平的维生素D3不总是显现出它的益处。从某些标准来看,当维生素D3含量“最佳”时母猪及其后代的生产性能要优于“高水平”供应。

  “We are seeing growing evidence that supplementing a sow’s diet with an optimal level of vitamin D3 can support her improved performance, as well as the lifetime performance of her progeny,” says Jon Bergstrom, Ph.D., senior technical support manager for DSM Nutritional Products.

  DSM高级技术支持经理Jon Bergstrom博士说:“越来越多的证据表明,当日粮中含最佳水平维生素D3时,母猪的生产性及其后代的性能都可得到改善。”

  “It is important to note ‘optimal’ doesn’t mean ‘as much as possible.’ We have tested varying levels of vitamin D3 supplementation, and the data is showing a moderate level of vitamin D3 supports better performance and growth than a higher or lower level.”

  “需要重点强调的是适量而不是尽可能的多补充,我们已经对维生素D3不同含量水平的日粮进行试验研究,数据表明中等含量的维生素D3改善生产和生长性能要优于高水平和低水平含量。”

  The three levels of vitamin D3 supplementation compared in the study included:

  · 363IU/lb (800 IU/kg), which is the vitamin D3 requirement recommended for sows by the NRC (2012) to prevent vitamin D deficiency.

  · 907IU/lb (2,000 IU/kg), which is the upper level of the range DSM recommends for sow supplementation (1,500 to 2,000 IU/kg).

  · 4,355IU/lb (9,600IU/kg), which is a high level of vitamin D3 supplementation thought safe for sows.

  研究中维生素D3这三个含量水平如下:

  · 363IU/lb (800IU/kg),这NRC(2012)推荐用于预防维生素D缺乏的维生素D3含量需求。

  · 907IU/lb(2000IU/kg),这是DSM推荐母猪饲料中供应维生素D3含量阈值(1500 到 2000 IU/kg)的上限。

  · 4355IU/lb(9600IU/kg),这是母猪日粮中维生素D3含量安全范围的高水平供应量。

  

  Lactation and vitamin D3

  A sow’s nutrient needs are three times higher during lactation than at other times in her production cycle. The research supported vitamin D3 supplementation as a tool to meet the sow’s nutrient needs.

  哺乳期和维生素D3

  母猪在哺乳期的营养需求比其他生产周期的需求高三倍。研究表明维生素D3的补充可帮助满足母猪的营养需求。

  Results showed sows fed the 907 IU/lb of Vitamin D3 more successfully maintained body condition during lactation. In addition, the research showed sows fed the 907 IU/lb of Vitamin D3 had the greatest average daily feed intake (ADFI) during lactation. The lowest ADFI was measured in sows supplemented with the highest vitamin D3 level.

  结果显示饲喂907IU/lb维生素D3的母猪在哺乳期能更好地维持良好的身体状况。此外,研究表明,喂养907IU/lb维生素D3的母猪在哺乳期的平均日采食量(ADFI)最大。补充最高维生素D3水平的母猪其ADFI最低。

  “This research showed 907 IU/lb of supplemental vitamin D3 supported greater lactation feed intake and reduced sow weight loss. Not only were the sows eating more to nourish their pigs, they were maintaining body condition, which can improve subsequent reproduction and the pigs produced in the sows’ lifetimes,” says.

  “这项研究表明补充907IU/Ib维生素D3母猪在哺乳期采食量更大,母猪体重的减轻量最少。不仅母猪吃的更多,可以更好地哺育仔猪,母猪及仔猪的还能更好的维持身体健康水平,这可以改善母猪之后的繁殖性能及其所有后代的生产性能。”Bergstrom说道。

  Increased performance measures in pigs

  The research also showed the benefits of supplementing sow diets with an optimal level of Vitamin D3 extended beyond the sows themselves. Pigs produced by sows fed the diets with 907 IU/lb of vitamin D3 experienced:

  提高的猪性能

  研究也显示在母猪日粮中供应最佳水平维生素D3不仅仅对母猪自身有利。饲喂907 IU/lb水平母猪生产的仔猪也受益匪浅:

  · Greater post-weaning average daily gain (ADG) than pigs farrowed by sows fed the higher or lower level of vitamin D3.

  · Greater than 8 pounds more weight gained from birth to market (176 days of age) when compared to pigs produced by sows fed the low level of vitamin D3, and nearly 3.5 pounds more weight gained than pigs from sows fed the high level of vitamin D3.

  · 断奶后平均日增重(ADG)高于由饲喂较高或较低水平维生素D3的母猪分娩仔猪。

  · 与饲喂低水平维生素D3母猪分娩的仔猪相比,从出生到上市(176日龄)多增重8磅;与饲喂高水平维生素D3组相比,多增重近3.5磅。

  “These results show the importance of sow vitamin D3 supplementation goes beyond supporting the sows’ nutrition and performance,” Bergstrom says.

  “This research also demonstrates sow nutrition can have a measurable impact on the progeny performance from birth to market, and that optimum vitamin nutrition for the sow can help the progeny reach their genetic potential.”

  “这些研究都显示了母猪日粮中供应维生素D3的重要性,不仅可以满足母猪的营养需求,还能改善它的生产性能,”Bergstrom说,“这个研究还表明母猪的营养对仔猪从出生到上市的这段时间的生产性能影响很大,饲喂最佳水平的维生素可帮助仔猪达到其遗传潜力。”
