Research note: A scald water surfactant combined with an organic acid carcass dip reduces microbial contaminants on broiler carcasses during processing.

Organic acids are applied to poultry carcasses during processing to reduce foodborne pathogens and spoilage microorganisms. Scald water surfactant agents employed to improve feather removal may enhance the efficacy of organic acids during processing. This study investigated the effects of concurrent application of a scald water surfactant and organic acid dip on microbial contamination of carcasses processed in a small-scale production model.

Effect of Limestone Particle Size and Potassium Supplementation on Growth Performance, Blood Physiology, and Breast Muscle Myopathy of Male Broiler Chickens.

The experiment investigated the effects of limestone particle size and dietary potassium (K) on live performance, blood physiology, and muscle myopathies in broilers raised to 35 days of age. A total of 384 Ross male broilers were placed in 24 floor pens and fed four diets during the starter (0-16 days of age) and grower (17-33 days of age) periods containing two limestone particle sizes (fine: 0.2 mm and coarse: 0.

The effects of high-oleic peanuts as an alternative feed ingredient on broiler performance, ileal digestibility, apparent metabolizable energy, and histology of the intestine.

Locally grown feed ingredients of high energy and protein content, such as peanuts, maybe economically feasible alternatives to corn and soybean meal in broiler diets. Even though normal-oleic peanuts have been demonstrated to be a viable feed ingredient for poultry, few studies to date have examined the use of high-oleic peanuts (HO PN) as an alternative feed ingredient for broiler chickens. Thus, we aimed to determine the effect of feeding HO PN on broiler performance, nutrient digestibility, and intestinal morphology.

Potential Transfer of Peanut and/or Soy Proteins from Poultry Feed to the Meat and/or Eggs Produced.

Previous studies have demonstrated that allergenic feed proteins from peanuts in the diets of layer hens are not detected in the eggs produced. Hence, in this study, we aimed to determine if soy and/or peanut proteins in poultry feed rations of broiler chickens or layer hens would be transferred or detectable in the meat or eggs produced. To meet this objective, 99 layer hens and 300 broiler chickens were equally divided into treatment groups and fed one of three experimental diets: control soybean meal and corn diet, whole unblanched high-oleic peanut and corn diet (HO PN), or a control diet spiked supplemented with oleic acid (OA) oil.

Meat quality and sensory attributes of meat produced from broiler chickens fed a high oleic peanut diet.

Previous studies have identified peanut meal prepared from normal-oleic peanuts as a suitable and economical ingredient for broiler feed. However, to date, no studies have examined the use of new, high-oleic peanut (HO-PN) cultivars as a feed ingredient for poultry. This project aimed to determine the effect of HO-PNs as a feed ingredient for broiler chickens on the quality and sensory attributes of the meat produced.

White striping and wooden breast myopathies of broiler breast muscle is affected by time-limited feeding, genetic background, and egg storage.

The effects of time-limited feeding, genetic background, and egg storage on white striping (WS) and wooden breast (WB) in broilers were studied. Male chicks (240) from 2 genetic backgrounds and 2 egg storage periods were fed on either an ad libitum (AL) or time-limited (TL) program from 7 d of age. A rapid growth strain (Growth) and an enhanced yield strain (Yield) of broiler breeder males were mated to a single female line and eggs were stored for periods of either 1 to 7 d or 8 to 14 d.
