The intensification of animal production systems presents a potential influence on the welfare of animals. The aim of this study was to evaluate the effect of three different systems on performance, welfare of Japanese quail (Coturnixcoturnix japonica) and their meat quality. Battery cages (50×30×30 cm) represent (T1), and floor pen (60×60×30 cm) with sawdust bedding (T2) and free range (200×200×140 cm) with sand-bathing area and nests. The experiment procedure involved seven birds per holding area and three replicates per treatment and overall of 63 quails. During five weeks of experimental period, behavioral activities were observed and recorded. Quails performance and meat quality were measured. Results showed that the behavioral activity indicators were higher welfare degree for quails in free range compared to floor pen and battery cage systems. Chemical composition and meat quality of breast meat were improved significantly (P<0.05) in free range compared with both other systems. This investigation has found that different rearing systems had a different behavior activity, and affect the quantitative and qualitative parameters of the breast meat of quails.
This research was conducted to evaluate the effect of probiotic supplementation on growth performance, gut microbiota, and hematology of local quails. Ninety-one-week-old quails were randomly distributed into three dietary treatments with three replicate per each for 42 days. The dietary treatments were: Treatment 1 which was control (no additive), standard diet added with Lactobacillus animalis bacteria 1 g/kg 1.35 × 109 colony forming units (CFU)/kg (PRO1) and commercial multi-strain probiotic (Lactobacillus acidophilus 2.75 × 1010 CFU, Streptococcus faecium 8.25 × 1010 CFU, and Bacillus subtilis 1.1 × 1010 CFU) (PRO2). Results showed that PRO1, isolated from chicken caeca, had probiotic properties to improve growth performance of local quail compared to the control group. In cecum digesta, addition of both types of probiotics significantly increased the number of Lactobacillus spp. and reduced the number of coliform bacteria at the end of the experiment. Furthermore, supplementation of both types of probiotics significantly increased the number of lymphocyte and reduced H/L ratio compared to the control group at the end of the experiment. While, no significant differences were observed between both types of probiotic. This research has established that L. animalis, which isolated in cecum of chicken origin, had the same data recorded when compared to commercial multi-strain bacteria probiotic by improved growth performance, gut microbiota, and hematology parameters and could be a convenient probiotic additive in dietary local quail.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
