“…Interestingly, Taylor et al (2020) found a relationship between range use and welfare, with better welfare scores with higher range use. In literature often systems are compared where the provision of an outdoor area or veranda is confounded with breed ( Sans et al, 2022 ; de Jong et al, 2022 ) which makes it impossible to determine the exact contribution of the outdoor area or covered veranda to broiler welfare. Environmental complexity can also be increased by applying various types of environmental enrichments which may have several functions, such as elevated resting areas combined with materials stimulating dustbathing and/or exploratory or foraging behavior.…”

“…Brazil is the main producer and exporter of chicken meat, and despite having produced 6.2 billion birds and 14.6 million tons of poultry meat in 2021 (Instituto Brasileiro de Geografia e Estatística, 2022), there is not official data about the quantity of birds produced in free-range farms. However, it is expected that the number is lower than other markets from in European countries where the consumption of these products reaches around 35% of source animal protein (Sans et al, 2021).…”

“…In recent years, there has been an increasing demand for free-range chickens, which have thus become a promising market in the poultry industry. This fact has happened because in chicken produced by conventional industrial system, there are problems related to animal welfare and the number of consumers willing to pay more for products from welfare-friendly systems has been increasing (Martínez-Pérez et al, 2017;Sans et al, 2021). Brazil is the main producer and exporter of chicken meat, and despite having produced 6.2 billion birds and 14.6 million tons of poultry meat in 2021 (Instituto Brasileiro de Geografia e Estatística, 2022), there is not official data about the quantity of birds produced in free-range farms.…”

The influence of sexual maturity on the meat quality of free-range chickens

This research study aimed to evaluate the influence of sexual maturity on meat quality parameters in chickens raised in a free-range system. The fully randomized design (FRD) used a (2x2) factorial scheme, with two sexes (male and female) and two categories of sexual maturity (immature and mature). Ninety birds (45 females and 45 males) belonging to the Label Rouge (Pescoço Pelado) strain were slaughtered at five different ages (70, 90, 120, 150, and 180 days). The physicochemical parameters, centesimal composition and shelf life of the meat were assessed. In both breast and leg cuts, sexual maturity promoted an increase in shear force and affected the meat color by increasing its redness (a*). Moisture was higher in leg meat after sexual maturity. In both breast and leg cuts, ether extract was higher in sexually mature females. Sexual maturity also caused a decrease in tenderness and shorter shelf life of the meat.

“…A comprehensive analysis of welfare criteria demonstrated the superiority of free range in sustaining better welfare conditions [14]. Furthermore, switching from a fastgrowing breed to a slower-growing breed improved animal welfare and reduced the need for antibiotics, creating a synergistic effect [15].…”

The global demand for improvement in the welfare conditions of broilers has generated the necessity to implement alternative rearing systems as well as less intensive growth hybrids. The majority of the data on alternative farming methods, notwithstanding their abundance, are the result of small-scale experiments. The present extended field study examined the effect of two different industrial farming systems on broilers’ antioxidant status, performance, and meat quality, including 13 replicates of each industrial breeding system (intensive conventional; free range) and two different chicken genotypes (fast growth; slow growth). The duration of the study was 51 months, and the total number of broilers was 260.000 for the conventional and 78.000 for the free-range system. The results showed that fast-growth chicks demonstrated a more satisfactory performance (in terms of body weight gain (BWG) and feed conversion ratio (FCR) with p ≤ 0.001), reduced serum lipid oxidation (p ≤ 0.05), and more tender meat. Contrarily, slow-growth chickens presented significantly higher total antioxidant capacity (TAC) in serum and thigh muscle (p ≤ 0.001), significantly lower (p ≤ 0.05) thigh muscle oxidation (in terms of thiobarbituric acid reactive substances, TBARS), increased protein and decreased fat content (p ≤ 0.05), and better smell, taste, color, and texture. In conclusion, the free-range farming system for slow-growth chickens may result in an overall higher nutritional value, sensory score, and serum and thigh muscle antioxidant profile than the conventional farming system for fast-growth broilers. However, fast-growth broilers exhibit better performance and might undergo less stress.
