Winning the weaning battle – butyrates for optimal gut health in piglets

Published on 25-10-2024 - Written by Kemin Animal Nutrition and Health

Butyrates are one of nature’s secret weapons for optimal gut health and integrity. Contrary to what we might think, the intestine cells, called enterocytes or colonocytes (for small and large intestines), use short fatty acids as a source of energy. In the hindgut, bacteria will produce butyrate, which will be used by the cells, but in the small intestine, there is little production. Butyrate is essential to develop the immature digestive system by:

  • Providing energy to the enterocyte.
  • Villi and Crypt growth improving the villi/crypt ratio.
  • Improve tight junction proteins.

The best results are seen with slow-release butyrates as they can reach all parts of the gut, creating a more substantial barrier against pathogens, improving the resilience of the gut to challenges and its ability to absorb nutrients. They can also be used after infections to restore the guts quickly. Let’s explore some experiences.

Energize for success: The vital role of butyric acid as energy source for the enterocyte on post weaning performance – field experience

The commercial trial was designed with:

  • 240 weaned piglets, 23 days old and weighing 6.7 kg.
  • 120 pigs were allocated to the control group and 120 to the Encapsulated Butyrate Slow Release (EBSR).
  • Butyrate was incorporated into pre-starter 1 and 2 diets, fed for 7 days each, as specified in Table 1.
  • Pigs were weighed, and feed consumption was recorded at the end of each phase.

During the pre-starter 1 phase, piglets in the EBSR group showed remarkable performance enhancements:

  • Average Daily Gain (ADG) surged to 235g/d compared to 192g/d in the control group (p<0.01) as seen in Figure 1
  • Average Daily Feed Intake (ADFI) increased to 297g/d from 278g/d (p<0.05) as seen in Figure 2
  • Feed Conversion Rate (FCR) improved to 1.28 EBSR from 1.47 in the control group (p<0.01) as seen in Figure 3
  • Piglets in the EBSR group were significantly heavier at the end of the phase, weighing 8.42 kg versus 8.12 kg (p<0.01).

In the pre-starter 2 phase, the EBSR group continued to outperform with an ADG of 301 g/d versus 276 g/d (p<0.05) and an ADFI of 400 g/d versus 383 g/d (p<0.05), as seen in Figure 4. 

 

At a standardized weight of 8.42 kg following pre-starter 1. The control group will require 2.52 kg of feed, whereas the EBSR group achieved the same weight with 2.2 kg, indicating a 0.32 kg feed reduction per piglet. Considering the higher cost of initial diets in production cycles, these findings suggest substantial cost savings for farmers, even though they are the less-used diets, whilst increasing performance and efficiency.
