Effect of Organic Production System on the Performance and Meat Quality of Two Purebred Slow-Growing Chicken Breeds

Abstract: the objective of the study was to compare the effect of organic and conventional rearing systems on the productivity and meat quality of Yellowleg Partridge (Ż-33) and Rhode Island Red (R-11) chickens. a total of 492 sexed experimental birds (Gallus domesticus) were assigned to four groups. In groups I-C and III-C, the Ż-33 and R-11 chickens were reared under intensive conditions following conventional farming principles. In groups II-O and IV-O, the Ż-33 and R-11 chickens were kept according to organic farmin… Show more

“…Drip loss was determined from meat weight loss after 24 h of cold storage at 4 • C. To this end, samples weighing 50 g were collected from the cranial part of breast muscle 15 min post-mortem and placed in airtight containers. The drip loss was determined as a percentage loss of initial weight [43].…”

“…In Poland, generally native and locally adapted breeds of hens are recommenced for alternative housing, as they are adapted to using the pasture and are less susceptible to unfavourable weather. These breeds are used for organic systems (Sosnówka-Czajka et al, 2017) and for production of capons (Calik et al, 2017) and poulardes (Obrzut et al, 2018;Krawczyk et al, 2019), high-quality, exclusive niche products (Kuźniacka et al, 2017). Hence, there is a need for studies on the bone quality in native and locally adapted breeds of hens, not only because of animal welfare but also because of the food safety (bone fragments in meat) and economic losses.…”

“…In our study, the PI percentage and level of PUFAs was higher in the breast muscle of the chickens fed diets without rancid oil. Similarly, Batkowska et al (2011) and Sosnówka-Czajka et al (2017) found the PI value to be higher in the muscle of birds with a higher PUFA content.…”
