“…Profitability is considered a critical factor and has a profound effect on the poultry industry, as it determines the financial success and sustainability of the business. In that, broiler production systems place significant importance on profitability (Sevim et al, 2021). According to the results obtained from this study, it is possible to suggest that rearing the Avian-48 and Cobb-500 strains may be more profitable due to their ability to produce more meat with less feed and in a shorter time, resulting in lower production costs overall.…”

The aim of this study was to assess the growth performance and profitability of four broiler strains raised in Egypt to identify which strains were most effective and profitable for broiler production in this region. A total of 24000 one-dayold chicks were separately allocated to 4 strain broiler groups: Cobb-500, Avian-48, Ross-308, and Indian River (IR), of the same age and size were used for the study. Each strain group was reared and housed in separate buildings under the same conditions with free access to feed and water. Each strain represented by 6000 birds, divided into five replicates of 1200 broiler chicks per replicate, and was randomly distributed in a completely randomized design into four groups reared to 42 days of age. Live body weight (LBW) and body weight gain (BWG) were recorded weekly. Also, feed consumption (FC), feed conversion ratio (FCR), and livability (%) were determined. The production efficiency factor (PEF), economic indices, and cost-benefit analysis were calculated to assess the profitability of each studied strain group. The results showed that there are significant differences in growth performance and other traits among the four broiler strains. The findings indicated that the Avian-48 and Cobb-500 strains were the most effective and profitable for broiler production under Egyptian conditions. In addition, the IR strain also showed good growth performance and feed efficiency. In conclusion, the study provides valuable insights into the performance and profitability of different broiler strains under Egyptian conditions, which can help inform decision-making in broiler production. By selecting the most effective and profitable broiler strains, producers can optimize their operations and potentially increase their profitability.

“…There are some experiments with other minerals and other forms (nano). Organic selenium supplementation, for instance, has improved the severity of FPD in ducks (Abdel-Hamid et al, 2020), while nano zinc did not cause any significant improvement (Sevim et al, 2021).…”

Nowadays, foot pad dermatitis and the associated loss of production and income is one of the major problems in intensive broiler chicken production. The third most valuable part of a broiler chicken is the legs. In the case of FPD, losses are realised as animals with foot pad dermatitis (FDP) eat, drink, and move less, and their performance is reduced, which causes serious loss of income. It also raises animal welfare concerns and can cause food safety problems. Development of the FPD and its frequency is influenced by several factors, individually or in combination: genetics, management, and feeding. In this article, we review the feeding causes of the development of FDP. Feedstuffs, rich in soluble NSP substances, low energy concentration in the diet, or luxury protein supply lead to low quality of the litter, predisposing birds to FPD. In addition, some minerals (Na, K, Cl) stimulate water consumption, while deficiency of others (Zn, Cu, Mn) affects epithelial tissue development and thus might provoke FPD.

“…Diet can also play a role in the development of footpad dermatitis in broiler chickens. An imbalanced diet with inadequate levels of certain nutrients, such as biotin, zinc, and choline, can contribute to poor skin and footpad health, making the birds more susceptible to footpad dermatitis [44,45]. Youssef et al [35] reported that dietary biotin (2000 µg/kg of diet) reduced the incidence of footpad dermatitis when litter had 25% moisture, but it failed to reduce it when litter had higher moisture contents (73% moisture).…”

The growth of the broiler industry has been accompanied with concerns over the environmental and social impacts on intensive production systems, as well as the welfare of the animals themselves. As a result, since the 2000s, there has been growing interest in alternative production systems that improve animal welfare and sustainability. In this context, it is important to prioritize the welfare of broilers in commercial production systems and to use reliable welfare indicators to provide consumers with information about the welfare of the animals they consume. Resource-based measures (RBM) are based on assessing the resources available to the birds in terms of their housing, environment, and management practices, such as stocking density, litter quality, lighting and air quality, etc. Outcome-based measures (OBM), also known as animal-based measures, focus on assessing the actual welfare outcomes for the birds, such as footpad dermatitis, hock burn, contamination or damage to feathers, gait score, mortality, etc. These OBM-based measures are one of the more direct indicators of welfare and can help identify any welfare issues. The present review highlighted the factors that affect animal welfare indicators focused on OBMs which can be used in the commercial broiler farms.
