“…The rearing stage is extremely important for the poultry chain, as a completely condemned carcass no longer generates a return on the investment made during rearing and adds disposal costs. Completely condemned birds are usually sent to waste processing facilities, where they are transformed into viscera meal through a water-filled pipeline (Giusti et al, 2022). The disposal of carcasses in integrated poultry production systems results in losses for the industry in terms of production volume and product value, as well as for the producers, who face reduced returns due to a decrease in the number of intact carcasses produced (Kruger et al, 2011).…”

Animal production systems and agribusinessFull-length research article Impacts of rearing-related factors on the slaughter characteristics of broilersABSTRACT -We investigated the influence of poultry rearing factors, including strain, type of ventilation, and sex on the slaughter characteristics of broiler chickens. Factorial analysis of mixed data was employed to analyze the data from broiler flocks slaughtered between 2018 and 2020 in Mato Grosso do Sul, comprising 2,684 flocks and 82,486,500 birds. The characterization information considered included age at slaughter, average weight, date of slaughter, percentage of pododermatitis, percentage of scratches, percentage of pre-slaughter condemnations, percentage of slaughter condemnations, percentage of total condemnation, percentage of field mortality, type of ventilation, strain, and sex. The factorial analysis of mixed data aimed to identify the relationships between pre-slaughter factors and slaughter characteristics. Five main components, explaining 85.5% of the total data variance, were derived from the analysis. Age, generated value per kilo of product, and percentage of pre-slaughter condemnations exhibited positive correlations. Negative pressure ventilation was found to be more closely associated with the percentage of pododermatitis, while the dark house system showed a stronger association with the percentage of total condemnation and percentage of pre-slaughter condemnation. The Cobb strain and female sex were found to be more strongly related to the generated value of the product. Strain, sex, and type of ventilation were identified as decisive factors influencing the characteristics of meat yields and the economic results of poultry activity in slaughterhouses. Moreover, it was observed that percentages of scratches and pododermatitis were negatively correlated with the value generated ($/kg) by broiler flocks, and they were more closely associated with positive pressure ventilation systems, Ross strain, mixtures of strains within the same flock, and male chickens. It was possible to prove the strong interdependence between the rearing stage of broiler chickens and the slaughterhouse, which needs to be considered in decision making by agroindustry to achieve an ideal rearing model.

“…Besides that, feed production in chicken farming is very climate intensive since feed ingredient manufacturing has the greatest negative environmental impact (Giusti et al 2022 ; Mostert et al 2022 ; Azmi et al 2023 ). The environmental impacts in the feed production subsystem were caused by the manufacture of feed ingredients (maize grain, soybean meal, wheat bran, rice bran, fishmeal) and energy use (electricity and natural gas).…”

Chickens are definitely among the most prevalent and broadly distributed domestic species. Among these, Ayam Cemani, also known as black chicken, is a rare Indonesian chicken breed originating from the island of Java. The main characteristic of this breed is that the body, both internally and externally, is entirely black. This is due to a condition named fibro melanosis, in which there is an over accumulation of melanin pigment in body tissues. In addition to this, Ayam Cemani meat results to be also higher in protein content and lower in fat. Moreover, Ayam Cemani meat is also known to have antioxidant and glucose-binding capacities. These properties make it very desirable within the market and consequently very expensive. Their meat is also used traditionally by tribal healers in the treatment of some chronic illnesses. In general, compared to other chicken species, the Ayam Cemani showed an higher genetic resistance to some infectious diseases commonly affecting poultry species. As regard the breeding, Ayam Cemani is a unique breed which may only be raised in specific locations, characterized to be a slowly growing breed with a lower body weight in comparison to the other poultry breeds. Nowadays, due to an improvement in the management, the nutrition and diseases control, it is possible to enhance their productivity. To date, there are not many studies in the literature on the specific breed of Ayam Cemani. For this reason, this review aims to provide a comprehensive overview of all the knowledge of the Ayam Cemani breed, the nutritional composition of the meat and consumer acceptance.
