“…This is in contrast with Roberson et al (2003) who did not observe differences in share of thighs between different turkey strains. Higher (P <0.001) share of thigh was found in males (29.84 %) than in females (27.45 %).…”

“…The results are consistent with Roberson et al (2003) who did not detect differences between turkey strains at 16 or 18 week of age. On the other hand, Werner et al (2008) found significant differences in different turkey hybrids.…”

“…Likewise, Fernandez et al (2001) and Damaziak et al (2013) discovered large differences in live weight at slaughter among genetic types. On the other hand, Roberson et al (2003) did not observe significant differences between strains for live weight. Males had significantly higher (P <0.001) live weight than females.…”

“…Since 1990, average time required for typical tom turkey to reach a target live weight of 16 kg has been decreasing an average of 1.5 day annually (Roberson et al, 2003). The selection of fast-growing turkeys focuses on high growth intensities and correspondingly high yields of the breast muscles.…”

The objective of this study was to evaluate the effect of hybrid and sex on carcass composition in turkeys. A total of 240 turkeys (males and females) of two different hybrids (BUT Big 6 and Converter) were used in experiment. Birds were housed in housing conditions suitable for turkeys. Turkeys were fed ad libitum with commercial feed mixture for given category of turkeys. Six males and six females of each genotype were slaughtered at 17 th weeks of age. Live weight and carcass composition were determined. The significant interactions between hybrid and sex were detected in live weight (P ≤0.001), carcass weight (P ≤0.001) and liver percentage (P ≤0.006). The highest live weight and carcass weight was observed in Converter males (17410 g, 13360 g, respectively), while the lowest was detected in Converter females (12115 g, 9390 g, respectively). Converter females had the highest liver share (1.47 %), whereas the lowest liver share was noted in BUT Big 6 females (1.20 %). The significant effect of hybrid was found in live weight, carcass weight and thigh percentage. The significantly higher live weight (P ≤0.003), carcass weight (P ≤0.002) and share of thigh (P ≤0.010) was detected in BUT Big 6 compare to Converter. Males had significantly higher (P ≤0.001) live weight, carcass weight and share of thigh than females.

“…In the past, turkey was regarded as a once a year treat but nowadays more and more people are aware of turkey's low cost and low fat (10% fat) compared to red meat and are making it a part of their regular diet (Castro Ferreira, et al, 2000). Moreover, meat obtained from turkeys is an excellent protein source and has a good price-quality ratio (Roberson, et al, 2003). In addition, in modern dietary trends, consumption of turkey meat is indicated as an adequate source of essential unsaturated fatty acids (Antony, et al, 2000).…”

The aim of the study was to determine the effect of a phytogenic additive on blood serum indicator levels and fatty acids profile of breast, leg muscles and liver in fattening turkeys. The experiment was realized in private turkey farm and in the Department of Animal Nutrition, Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra. A total of 300 clinically healthy female turkeys (broad-breasted white turkey, hybrid XL) were used in the experiment. Female turkeys were randomly divided into two groups (150 pcs per each). In the control group, turkey were fed with standard complete feed mixtures for fattening, in the experimental group, standard diets from the beginning to 12th week were supplemented with the a blend of essential oils from origanum, anise and citrus fruits as well as a prebiotic rich fructooligosaccharides in dosage 1kg per 1000 kg of feed mixture. Fattening lasted 18 weeks. Blood serum was collected at the end of the experiment, during the slaughter of birds. Samples of breast and leg muscles, and liver for fatty acids composition evaluation were collected during birds dissection (10 samples per each group). After the 12 weeks of phytoadditive supplementation, a tendency of lower activity of serum alanine aminotransferase (53.963 vs. 3.499 U/L) and aspartate aminotransferase (6.238 vs. 1.012 U/L) in experimental group of turkeys was found (P<0.01). The same tendency was analyzed in content of phosphorus (P<0.05). Compare to the control group, in the experimental group have been detected significantly (P<0.01) lower concentration of capric acid in leg muscle, lauric and myristic acid in both evaluated muscles, palmitoleic acid and stearic acid in the liver. Additionally, the phytoadditive supplementation markedly (P< 0.01) increased content of following SFA: lauric, myristic and palmitic acids in the liver, pentadecanoic, heptadecanoic and stearic in both evaluated muscles. In the case of unsaturated fatty acids have been detected that the phytogenic feed additive in breast and leg muscles of birds markedly increase the content of cis-11,14-eicosadienoic acid (0.209 vs 0.276 and 0.242 vs 0.298 % of crude fat, respectively); compare to control group, leg muscle of individuals from experimental group have higher (P>0.01) content of cis-8,11,14-eicosadienoic and arachidonic acids. The phytoadditive supplementation significantly (P<0.01) decreased content of some unsaturated fatty acids in turkeys tissues, as well. In experimental group of turkey have been recorded lower level of elaidic and oleic acids in the breast muscle and cis-11,14-eicosadienoic and arachidonic acids in the liver, compare to birds from control group.Keywords: additives, aromatic plants, blood serum, fatty acids profile, turkey Abstrakt Cieľom práce bolo determinovanie vplyvu fytogénneho aditíva na ukazovatele krvného sera a profil mastných kyselín v prsnom, stehennom svale a pečeni výrkmových moriek.
