This study evaluated the impact of electron beam (eBeam) treatment at 3 and 4 kGy — both below the regulatory limit of 4.5 kGy for refrigerated poultry products — on meat quality parameters (pH, cook loss, color, and texture) and sensory attributes (aroma, flavor, taste, and mouthfeel) of ground chicken and ground turkey under conditions simulating commercial processing. At 3 kGy, no significant differences were observed between treated and untreated controls in pH, texture, or most sensory attributes, Read This Summary

   Claude responded: This study by Kalapala (University of Arkansas), published in Poultry Science (Vol. This study evaluated a photo-electrochemical (PEC) treatment system using 1.6% curcumin as a photosensitizer to disinfect poultry processing wastewater from scalding and inside-outside bird washer (IOBW) systems, testing two reactor sizes (7-L and 30-L) at 70 and 100 V over 300 minutes. Aerobic bacterial populations were reduced by 2.0 to 2.9 log Read This Summary

This study examined whether 3% dietary Spirulina platensis supplementation could mitigate the negative effects of heat stress in broilers across three treatment groups: normal temperature, heat stress, and heat stress with microalgae. Heat stress appeared to reduce final body weight and daily weight gain relative to normal conditions, while microalgae-supplemented birds showed improvements in body weight and feed conversion ratio compared to heat-stressed controls. Beyond growth performance, Read This Summary

This observational study characterized the early-life behavior of 75 Ross 308 broiler chicks through continuous 24-hour observation from day 1 to day 7 post-hatch to understand how behavior changes with age and time of day. Findings suggest that resting and sleeping predominated in early post-hatch days and gradually decreased as active behaviors — including standing, walking, running, jumping, eating, drinking, foraging, sparring, and playing — increased over the week, consistent with rapid early Read This Summary

Evaluating dietary natto ( Bacillus subtilis var. natto strain TTCC903) in aging laying hens suggests its potential to mitigate environmental heat stress . Data indicate that a 0.5% inclusion level may help maintain egg production and improve feed conversion efficiency during thermal stress . The treatment also appears to preserve egg quality by stabilizing eggshell strength and reducing defective egg rates Read This Summary

A 35-day study on 300 Cobb 500 and Ross 308 broilers tested whether a fructooligosaccharide and multi-species probiotic synbiotic (0.5 g/kg) could improve growth, gut health, tibia strength, and behavior. Strain choice had the biggest effect. Cobb 500 birds outperformed Ross 308 on weight and feed intake regardless of diet. The synbiotic improved duodenal villi height and added some tibia weight, but did not move body weight, FCR, leg strength, or lameness. Bottom line for producers: strain selection Read This Summary
