| الوصف: | The biological material which was studied has been represented by 34 ROSO SL hybrid that lay eggs, of 45 weeks of age. We have analyzed the 45 weeks age as a middle age for the intensity of egg laying on the level of over 80%. Measurements have been made for the following conformation traits: body weight, body length, former depth, former width, pelvis width, length of the breast-bone careen, thoracic perimeter, shin perimeter and length. The measurements have been made according to the methodology and the known speciality instruments. The observation data have been overworked, this way we have established the average values and the variability parameters for the traits we followed, which fit the values presented in the specialty literature and are even over these for the age group chosen for studies. The body weight of 2058.82 ± 38.49 g, superior to the one mentioned in the technological guide, confirms a proper unrolling of the body weight deposits and shows that the Roso SL hybrid will properly support both the body growth in weight and also egg production in parallel, respectively this double effort, fact that gives the hybrid a higher quality. Other registered values are of 18.06 ± 0.15 for the body length, of 10.85 ± 0.11 cm for the length of the breastbone careen, together with the sizes which maintain a proper egg production, such as the width of the pelvis of 9.75 ± 0.14, the former width of 6.78 ± 0.10 cm and, why not, even the former depth of 10.72 ± 0.12. We would also notice an appreciable uniformity of these values, the limits of the variation factor being between 4.66 (length of the shin) and 8.36 (former width). The values that the biological material represent for the characters we studied, convince us about the hybrid’s availability for being exploited in the egg production. |
