“…Wet litter promotes pathogenic proliferation and amplifies emitting of ammonia gas, as a result, increasing the incidence of contact dermatitis and related footpad lesion and breast blisters ( Shepherd and Fairchild, 2010 ). Footpad dermatitis ( FPD ) and hock burn ( HB ), the skin of the foot and hock inflamed with necrotic lesions, have been recognized as the main reasons causing lameness in broilers ( Hossain et al., 2018 ).…”

The aim of this study was to investigate the effect of a dietary probiotic supplement on bone mass and meat quality of broiler chickens. Two hundred ten 1-day-old male Ross 708 broiler chicks were divided among 21 floor pens (10 chicks per pen). The pens were randomly distributed to 1 of 3 dietary treatments containing a probiotic, Bacillus subtilis, at 0 (control), 0.25 ( 0.25X ), and 0.5 ( 0.5X ) g/kg (n = 7). Gait score, footpad dermatitis ( FPD ), leg straightness, and hock burn ( HB ) were examined at day 33, and a latency-to-lie test was performed at day 34. At the end of the experiment (day 35), plasma, right leg, and litter samples were collected for mineral contents, meat quality, bone morphometric parameters, and litter quality assessments. The results indicated that probiotic-fed birds stood much longer during the latency-to-lie test with a greater tibial length, weight, and strength as well as higher plasma levels of calcium and phosphorus compared with the controls. In addition, probiotic-fed birds' leg muscle had higher color lightness at both 30 min and 5 h postmortem and greater water-holding capacity with a trend for less cooking loss ( P = 0.056) and lower pH values ( P < 0.05) at 5 h postmortem. Probiotic-fed birds' leg meat was tastier ( P < 0.05) at 24 h after slaughter. These probiotic effects were greater in the 0.5X group than in the 0.25X group. There were no treatment effects on other measured parameters including gait score, HB, FPD, tibial lateral and medial wall thickness, diaphysis and medullary canal diameters, robusticity and tibiotarsal indexes, plasma magnesium concentrations, and litter moisture and pH values ( P > 0.05). These findings indicate that the probiotic supplement could be a useful management tool for improving broiler production and welfare by enhanced bone mass and meat quality.

“…The ideal litter material should have a moisture content of 20-25%, a pH of 8-10, and ammonia content should not exceed 25 ppm (Dunlop et al, 2016 andGençoğlan andGençoğlan, 2017). Excess moisture in the litter increases the incidence of breast blisters, skin bums, scabby areas, bruising, condemnations and downgrades (Hossain et al, 2018). Wet litter is the primary cause of ammonia emissions, one of the most serious performance and environmental factors affecting broiler production today (Rizt et al, 2017).…”

The study was implemented at the National University of Lesotho with the aim to find a potential litter material for use in broiler production. The study followed a completely randomized design with four litter treatments replicated three times. A well ventilated house divided into 12 pans was used where each pan or a replicate contain 15 birds with a total of (n=180) birds. Feeding and watering were done on ad libitum basis while the normal routine for broiler production was followed. Litter treatments were made up of control represented by wood shaving and it was compared to dried pine leaves, decomposed kraal manure and sand. All litter materials were applied at the depth of 10 cm. Data was collected on the following parameters broiler production, feet health and chemical and physical properties. Litter material treatment had no significant influence on feed intake, body weight, body weight gain, and feed conversion ratio and mortality rate. Regarding broiler feet health litter treatment had significant influence on foot pad dermatitis while hock burns and broiler temperature were not statistically different amongst litter treatments. Litter evaluation results revealed that different litter sources were differing significantly in terms ammonia emissions, water holding capacity. pH and bulk density while litter temperature did not differ significantly between litter treatments. It was concluded that both dried pine leave and decomposed kraal manure are potential sources that could replace wood shavings in broiler production. Dried pine leaves ideal for improved production while decomposed kraal manure deemed fit for ensure good feet health. It is therefore recommended that farmers in Lesotho can use both decomposed kraal manure and dried pine leaves to replace wood shavings.
