“…Our results coincide with those shown by previous authors (Ponte et al, 2008;Dal Bosco et al, 2012;Bosco et al, 2014;Popova et al, 2018) both in the predominant fatty acids, and in their value in other medium-growing genotypes.…”

A total of 160 medium-sized one-day-old male chicks reared in organic conditions were studied individually from the first day of their life until slaughter (120 days). Two weather periods were considered, being period C colder than period H. A total of 24 chickens per period were randomly selected, then the breast muscle (m. Pectoralis major) was extracted for analysis. Individual fatty acids were measured by gas chromatography and expressed in grams per 100 g of fat. From the values obtained, total lipid fractions were calculated. Near infrared spectroscopy spectra (NIRS) were recorded on the surface of the breast without manipulating. Breast from chicken reared in H period had significantly lower (p<0.05) saturated fatty acids / polyunsaturated fatty acids (SFA / PUFA) ratio, and increased (p<0.05) content in PUFA and n-6. However, no significant differences were observed on the content of individual fatty acid. NIR system was not able to correctly classify the samples according to the breeding period.

“…Omega 3 and omega 6 fatty acid content of broiler meat was highest and had significant (p ≤0.05) difference to Manado chicken. According to Popova et al (2018) Age significantly affect the palmitic acid (C16:0) content in the breast, leading to decrease in the older chickens (p <0.01) whereas the proportion of C18:0 in both breast and thigh increased with advancing age (p <0.001). While no effect of line observed in regard to C16:0 in the muscles, the content of C18:0 in the breast significantly differed between two lines and its proportion decreased significantly with age.…”

India is the fourth largest chicken producer after China, Brazil, and the USA. The per capita consumption of chicken has gone up from 400 gm to 2.5 kg per year, and human nutritionists recommend 10 kg chicken per year. To feed billions of Indian population, there is a lot of scope for the chicken industry to enhance the production. At the same time, many studies revealed that genotype significantly affects functional properties as well as the nutritional characteristics of chicken. The fast-growing chicken strains appear to be more attractive both for industrial and consumer use whereas from a nutritional point of view meat from slow growing chicken strains appears healthier (less fat and higher content of n-3 PUFA) and thus might better fit with the consumer's prospect. In acceptability for meat quality, slow growing chicken showed the better sensory quality of the chicken breast meat. Thus, for the demand of customer's for the higher quality of chicken meat, it is suggested to use slow growing chicken in alteration to fast-growing broilers. This review deals with the effects of genotypes (slow growing and fast growing broilers) on physicochemical and organoleptic traits of chicken.

“…Two such lines are used in this study-the autochthonous La Belle -representative for the national gene pool in Bulgaria, as well as the old French Bresse Gauloise. Research on these lines concerning their carcass and meat quality are relatively few (Popova et al, 2016;Popova et al, 2017;Popova et al, 2018). However, based on the results so far, these lines draw much interest in finding possibilities and best rearing practices for raising slower-growing chickens to produce high quality meat.…”

The study was carried out to compare the carcass quality and the chemicalcomposition of breast and thigh meat in two lines of slow-growing male chickens -La Belle (LB) and Bresse Gauloise (BB) reared conventionally or outdoors, havingaccess to pasture. The birds were slaughtered at 12 weeks of age. Two-wayANOVA was used to assess the effect of the rearing strategies as well as the line onthe carcass quality and meat chemical composition. Rearing system affectedsignificantly the carcass traits of the birds. The lines reared on pasture had lowerlive and carcass weight as well as lower dressing percentage (P<0.001). On theother hand they had higher percent (P<0.001) of the edible by-products (neck andgiblets). The percentage of the breast meat was significantly reduced in the birdsthat had access to pasture (P<0.001), while thigh remained unaffected. Thepastured chickens displayed higher part of the wings (P<0.01). Outdoors rearinginfluenced the chemical composition in the breast and thigh meat of the lines.Chickens reared on pasture were characterised by lower lipid content (P<0.01) inbreast and reduced protein in thigh (P<0.05), as well as increased moisture in bothkinds of meat, however depending on the line (P<0.05). Furthermore, pastureaccess resulted in reduced ash content of the breast meat (P<0.001), which waslower in the LB chickens (P<0.01), while in thigh this parameter was stronglydetermined by the interaction of the rearing system and line of the birds (P<0.01).
