“…The foot callus is characterized by superficial to deep necrotic and inflammatory lesions of the plantar surface of the paws and toes, is also known as pododermatitis or contact dermatitis (SHEPHERD & FAIRCHILD, 2010). Some of the factors involved in the higher or lower callus occurrence are management, nutrition, body weight, genetics and sex (SHEPHERD & FAIRCHILD, 2010;MARTINS et al, 2016). Thus, higher feed intake and excrement volume results in increased litter moisture, which is harmful (MARTINS et al, 2016).…”

Thus, higher feed intake and excrement volume results in increased litter moisture, which is harmful (MARTINS et al, 2016). There was a higher occurrence of callus on the feet for the Ross 95 hybrid (P<0.05); in relation to the seasons, in spring the occurrence was higher and was lower in summer and autumn (P<0.05), and in this case weight was not a determining factor (Table 3).…”

Condemnations in the broilers abattoirs can represent an overview farms health and effectiveness of welfare programs, as well as predisposition between hybrids. The aim of this study was to investigate the prevalence of condemnation among four commercial broiler hybrids and the oscillation of condemnations in different seasons in a poultry abattoir. Data from condemnations of the Federal Inspection Service of a slaughterhouse were analyzed during one year, in which a total of 12.81% of partial condemnations were observed and total condemnations represented 0.41% of slaughtered broiler. There was a difference in total and partial condemnation among the hybrids evaluated, with Hubbard hybrid being the one with the highest number of condemnations (0.67% - 17.71%), followed by Ross 95 (0.42% - 14.21%), Cobb (0.30% - 10.03%); and Cobb Fast (0.26% - 9.29%). The analysis between the seasons showed a higher conviction rate in winter and a lower rate in autumn for both total and partial condemnation. Hubbard had the highest rates and Cobb Fast the lowest for most causes of condemnation. We concluded that the metabolic cause led to higher losses by total condemnation, while contamination or technopathies represented the highest rates in partial losses. The broiler hybrid and the time of year may influence the causes of condemnation in the abattoir. This information should be considered by the abattoir and the farms in sanitary planning, considering the financial impact due to losses by condemnations of carcasses.

“…On this binomial scale, food pad scores were classified as 1 (no lesion: score 1), 2 (initial lesion: scores 1 and 2), and 3 (severe lesions: scores 3 and 4). The diet-directed response data were analyzed using the χ2 test (Martins et al, 2016). The means were separated using Tukey's multiple range test procedures of the SPSS software (Version 21; IBM SPSS 2012) when treatment effect was significant (P＜0.05).…”

Differential Effects of Dietary Methionine Isomers on Broilers Challenged with Acute Heat Stress

et al. 2019

In this study, we investigated the effect of methionine isomers (D-and L-methionine) on growth performance, blood metabolite levels, nutrient digestibility, intestinal morphology, and foot pad dermatitis in broilers challenged with acute heat stress. In total, 240 broilers were randomly allocated in a 2×2 factorial arrangement consisting of two dietary treatments (D-vs. L-methionine) and two thermal environmental conditions (thermo-neutral vs. acute heat stress). Methionine isomers were added to the diet as an ingredient according to the diet formulation. The broilers were exposed to acute heat stress at 33℃ for 5 h on day 14. The average daily gain and feed conversion ratio of birds fed L-methionine were higher than those fed D-methionine (P＜0.05) from the time of hatching till 21 days. Induced acute heat stress impaired (P＜0.05) the daily gain and feed intake of the broilers on day 21. Furthermore, the blood urea nitrogen levels of birds subjected to acute heat stress on days 14 and 21 were higher (P＜0.05) than those of their counterparts. Longer villi (P＜0.05) were observed in broilers fed L-methionine-supplemented diet than in those fed D-methionine-supplemented diet on day 14, irrespective of thermal environmental conditions. Heat stress reduced (P ＜0.01) nutrient digestibility of the broilers on days 14 and 21. Higher incidence and severity of foot pad dermatitis were observed (P＜0.05) in broilers fed diet containing D-methionine than in those fed L-methionine-supplemented diet. In conclusion, L-methionine-supplemented diet improved growth performance, overcame growth depression, and reduced the incidence of foot pad dermatitis when broilers were exposed to acute heat stress in the starter period.

“…There could be an important correlation between macro and micro scores of foot pad in broiler raised in different floor system (Louton et al, 2020). Martins et al (2016) showed that the lesion scores assigned were compatible with the histopathological results, showing that the higher the score, the more severe were the dermal and epidermal lesions. Lesions affecting the deeper layers of the skin as histopathologically were observed more in partially slatted plastic flooring and conventional deep litter (Score from 0 to 4).…”

Broiler housing and management have become important for both manufacturers and researchers, with the increasing commercial demand over the years. The most important factor that creates the management conditions is floor housing system selection. The reason floor housing systems are important is that they allow broilers to reduce contact with the excreta and help excess moisture to be absorbed and controlling ammonia level. Poor litter conditions trigger painful pododermatitis that will affect animal welfare. Footpad dermatitis is a form of contact dermatitis affecting skin and has most commonly been associated with poor litter condition or irritating and unsuitable materials in broilers. This study was made to investigate the histopathologic characteristics of footpad lesions in fast-growing broiler chickens raised in different floor housing systems. There were four groups in the experiment as conventional deep litter flooring, fully slatted plastic flooring, fully slatted wood flooring, and partially slatted plastic flooring. After the slaughter process, random samples were taken from the birds representing each macro score (if occurred, from 0 to 4) from each group. For histopathologic examinations, footpad samples were fixed, and routine histological examinations were applied. Microscopic examination has been defined in five different scores, from the non-lesion score 0 to the score 4 with severe necrosis. As a result of macroscopic and microscopic evaluations, it has been determined that plastic and wooden slatt materials have positive effects on foot health. Focusing future studies on the correlation between the size and depth of macroscopic lesions and the size and depth of histological lesions would be beneficial to determine a reliable correspondence between antemortem and postmortem lesion score of footpad in broiler.
