The Effect of Dietary Oil or Cake in the Diets of Broiler Chickens on Growth Performance, Fatty Acid Profile, and Sensory Quality of Meat.

The aim of the present study was to determine the effect of supplementing the diets of broiler chickens with oil or cake as a source of polyunsaturated fatty acids (PUFAs) on their growth performance, fatty acid profile, and sensory quality of meat. The 456 Ross 308 broilers aged 21-42 days were divided into 3 groups with 4 replicates of 38 birds in each. Chickens in the control group I (CTR) were fed a standard grower-finisher feed mixture containing 60 g/kg rapeseed oil.

The use of primed in situ synthesis (PRINS) to analyze nucleolar organizer regions (NORs) and telomeric DNA sequences in the domestic chicken genome.

One of the most often analyzed avian genomes is the domestic chicken genome (Gallus domesticus) whose diploid number is 2n = 78. In the chicken karyotype, similarly to other birds, there is a group of microchromosomes for which the determination of morphology and banding pattern is impossible using classic cytogenetics methods. The aim of this study was to evaluate telomeric and rDNA repetitive sequences in the chicken genome by the PRINS technique as an alternative method to fluorescence in situ hybridization.

The effect of dietary CLA supplementation on meat and eating quality, and the histochemical profile of the m. longissimus dorsi from stress susceptible fatteners slaughtered at heavier weights.

The influence of adding 2% CLA to the morning feed of a group of 20 crossbred fatteners from 70 to 130 kg on meat quality, eating quality and dietetic value of m. longissimus dorsi was evaluated compared with a group of 20 controls. Addition of 2% CLA in feed did not influence fattening and slaughter results and also some traits of meat and eating quality.
