Impact of Dietary Methionine Levels and Sources on Performance and Health of Foot Pad in Broilers

Abstract:
Background and Objective: Foot Pad Dermatitis (FPD) is a widespread problem in poultry production and constitutes a welfare issue. The objective of this study was to test the surplus dietary levels of methionine and its sources (DL-Met/MHA) on performance and health of foot pad in broilers. Methodology: One-week-old ♀ broilers were divided randomly into 5 groups for 28 days. All diets were basically composed of wheat (64%) and soybean meal (30%). One group was fed a basic level of Met in the diet (3.5 g kg–1 diet) without any supplementation. The other groups were fed with different Met levels (+1/+2 g kg–1 diet) as DL-Met or as methionine hydroxy analogue. External assessment of foot pads was done weekly. Individual body weight was recorded weekly on the day of scoring. Results: Met supplementation improved the body weight gain, so that the means of Body Weights (BW) differed among the groups after 4 weeks of trial. Feeding unsupplemeted Met diet resulted in the significantly lowest BW (1627 g). Furthermore, feeding higher levels of Met in form of DL-Met (+1 g kg–1 diet) led to the highest BW (1916 g) numerically. The highest significantly FPD scores (5.2±0.6) was found in the control group in comparison to other experimental groups. However, using dietary DL-Met in higher levels (+2 g kg–1 diet) led to numerically lower FPD scores (3.2±0.8) than using only+1 g kg–1 diet (4.7±0.4). Conclusion: It means that there is a specific function of Met regarding performance and foot pads.
