Day 2 of Asian Agribiz’s Pig Feed Quality Conference addressed ‘Nutritional strategies to build a robust pig’, to help pig producers achieve profitability. Below are some highlights.
Better FCR always leads to better ROI
There is a strong correlation between FCR and ROI in pig diets, said Chaiyapoom Bunchasak, Professor at the Department of Animal Science, Faculty of Agriculture, Kasetsart University in Thailand. “For better economic returns, it is best to improve FCR.” Improving FCR means better nutrient usage, less metabolic stress, and overall improved immunity for pigs, he explained. He noted that nutrient requirements in pig feed formulation need to consider the final consumer. Integrators especially would have to focus their formulation on getting the best ROI and FCR.
Accuracy vs precision in diets
Accurate rather than precise feed formulation helps boost efficiency in diets, said Prof Bunchasak. Talking about the difference between accuracy and precision, he noted that calculating feed formulation using ‘total basis’ for amino acids was precise but using Standardize Ileal Digestibility (SID) was more accurate. When it comes to energy calculations, he recommended using net energy (NE) values rather than ‘metabolizable energy’ values of ingredients to be accurate. Following accuracy would thus help reduce crude protein use, boost immunity, and lower feed costs, he said. SID and NE values of alternative ingredients also give a better picture during formulation.
Low protein diets can improve immunity
Low protein diets can increase amino acid digestibility in pigs, leading to better immunity and health. Prof Bunchasak explained that low protein content would not impact growth performance if there were sufficient digestible amino acids in the diet. “High protein in the gut can impact microbiota modulation, leading to gut inflammation and stress,” he said. Producers can stop this by using low crude protein diets, which saves money.
Feed strategies help reduce cytokine storm in ASF pigs
Feed strategies can help reduce the cytokine storm in ASF-infected pigs. Prof Bunchasak believes that this cytokine storm comes from the inflammation of the gut resulting from the virus. He said reducing gut inflammation using low crude protein diets could help with the cytokine storm. Other feed strategies that can reduce inflammation include the use of Omega-3 and the reduction of antioxidants in the body.
