ABSTRACT

One of the main causes of death in newborn piglets is the low level of energy reserves to maintain their body temperature, which can lead to hypothermia and, subsequently, death. Thus, the objective of this study was to evaluate the effect of soybean oil supplementation to sows in the first three days after farrowing to save piglet fat reserves through the higher nutritional intake of sow milk. In total, 604.5, 750, 1000, 1250 and 1500 g of soybean oil were provided for each sow during the three days of supplementation. A total of 60 sows were evaluated per treatment, distributed in a random block design, supplemented in the first three days after farrowing with soybean oil added on top of the feed at the time of feeding. Performance and reproductive data and milk samples were collected from the sows to determine fat levels. Piglets were evaluated for fall-back rate and survival. There was no significant effect of soybean oil supplementation on any of the parameters evaluated for both sows and their milk. Therefore, soybean oil supplementation for sows in the first three days after farrowing does not influence performance parameters, reproduction and milk fat of the sows and mortality and fall-back rate of the piglets.

摘要

新生仔猪死亡的主要原因之一是维持体温的能量储备水平低，这可能导致体温过低并随后导致死亡。因此，本研究的目的是评估母猪在分娩后前三天添加大豆油的效果，通过更高的母乳营养摄入量来节省仔猪脂肪储备。在补充的三天内，总共为每头母猪提供了 604.5、750、1000、1250 和 1500 克大豆油。每个处理总共评估了 60 头母猪，以随机区组设计分布，在分娩后的前三天在饲喂时在饲料顶部添加豆油进行补充。从母猪身上收集性能和繁殖数据以及奶样以确定脂肪水平。评估仔猪的倒退率和存活率。补充大豆油对母猪及其乳汁评估的任何参数均无显着影响。因此，母猪在分娩后的前三天补充大豆油不会影响母猪的性能参数、繁殖和乳脂以及仔猪的死亡率和倒退率。
