Comparison of growth performance and carcass traits of Japanese quails reared in conventional, pasture, and organic conditions

Abstract

-This study was conducted to compare live weight, feed intake, feed conversion, mortality rate, and some carcass characteristics of Japanese quails reared under organic and conventional conditions. A total of 180 one-day-old quail chicks were randomly divided into six groups -Conventional, consuming conventional feed ad libitum; Control (C), consuming organic feed ad libitum; C+P, consuming organic feed ad libitum + pasture; 80C+P, consuming 80% of control + pasture; 70C+P, consuming 70% of control + pasture; and 50C+P, consuming 50% of control + pasture -with three replicates. The conventional group was kept for 6 weeks, while the control, C+P, 80C+P, 70C+P, and 50C+P groups were reared until the end of 10 weeks of age. Raising systems significantly affected live weight, feed intake, and feed conversion. The analysis showed that the meat yield of quail raised in organic conditions had better results than those raised in conventional conditions in terms of appearance, color, aroma, and flavor. The group consuming 50% of control plus pasture was more advantageous than the other organic groups and the conventional group at the end of the 10-week fattening period. The organic production system can be a good system to meet the demand of consumers who seek more natural products.

Effect of dietary pomegranate peel powder on productive traits, blood chemistry, economic efficiency and the expression of FSHR and LH-β genes in two strains of laying Japanese quail

“…These results came in accordance with Fadhil et al (2018) who reported an obvious higher productive parameter including carcass weight of the white strain compared with the brown strain. In contrast to the present results, Inci et al (2016) reported higher values of carcass dressing% of the brown strain.…”

Difference in the Carcass Quality and Meat Chemical Composition in Two Lines of Slowgrowing Chickens With or Without Access to Pasture

“…On the other hand, the authors did not find any effect on wings while the trunk was increased in the pastured birds. Contrary to our results, Küҫükiyalmaz et al (2014) and Inci et al (2016) did not find significant change in the percentage of breast meat respectively in broilers and quails as affected by organic rearing with pasture access, however the latter observed decrease in the drumstick ratio in the male birds on pasture, compared to the conventional rearing.…”

Evaluation of growth performance and slaughter traits of Aseel chicken grown with and without outdoor access

“…Similar to these ndings, Ahmad et al (2019) found that birds reared indoor achieved higher drumstick weight compared to free-range and part-time free-range systems. Inci et al (2016), likewise, observed variations in drumstick weight of quails under different rearing systems. Among the varieties, Sindhi showed increased drumstick yield than Peshawari.…”
