“…One of the most pressing issues is maintaining the high immune status of these animals with the most intensive breeding technology. This is impossible without a thorough and comprehensive study of the immunomorphology of the hemopoietic and lymphopoietic organs, in particular, their morphogenesis in the period of postnatal adaptation (Vakulenko & Ochkovs'ka 2007;Savchuk & Demchuk, 2009).…”

The meat productivity of animals, including rabbits, depends on many decisive factors, the main of which are the quality and type of feeding, housing conditions, the use of intensive rearing protocols and breed affiliation. Now in industrial rabbit breeding, improved hybrid crosses are preferred, which, in terms of their quality characteristics, are significantly dominated by the usual domestic rabbit breeds. Therefore, it is important to have a balanced model with species and age characteristics of the syntopy and morphology of internal organs, in particular hemo-and lymphopoiesis, in this animal species. There have been established main anatomical, topographic and morphometric parameters of the spleen and visceral lymph nodes (cranial mesenteric and cranial mediastinal) for rabbits of the meat productivity direction from the age of 1 day old, 10-, 20-, 30-, 60-and 90-day-old. Each age group consisted of 6 rabbits. All experimental animals were clinically healthy, not vaccinated and not treated against ecto-and endoparasites. The features of the topographic location of the organs were described, as well as length and width parameters, and absolute and relative masses were determined. It was identified that the topography of the spleen and lymph nodes corresponds to the generally accepted species principles for the placement of these organs in rabbits. A relationship has been established between a sharp increase in the dynamics of organ morphometric parameters and the rapid development of a hybrid cross in the period from birth to reaching 90 days of age. Organs' morphometric parameters in general correlate with age.Keywords: secondary organs of hemo-and lymphopoiesis; morphogenesis; structural and functional organization; organs' absolute and relative mass; organs' length and width; rabbit breeding Топографія і динаміка морфометричних параметрів селезінки та лімфатичних вузлів кролівАнотація. М'ясна продуктивність тварин, в тому числі кролів, залежить від низки вирішальних факторів, основні з яких -якість і тип годівлі, умови утримання, застосування схем інтенсивного вирощування та породна приналежність. Нині в промисловому кролівництві надають перевагу вдосконаленим гібридним кросам, які за своїми якісними характеристиками значно переважають звичні породи свійських кролів. Тому важливо мати виважену модель з видовими і віковими особливостями синтопії та морфології внутрішніх органів, зокрема гемо-і лімфопоезу, у цього виду тварин. Встановлені основні анатомо-топографічні та морфометричні параметри селезінки і вісцеральних лімфатичних вузлів (краніального брижового та краніального середостінного) для кролів м'ясного напрямку продуктивності від добового,10-, 20-, 30-, 60-та 90-добового віку. Кожна вікова група складалась з 6 кролів. Всі піддослідні тварини були клінічно здорові, не вакциновані та не піддавалися обробці від екто-та ендопаразитів. Описані особливості топографічного розташування відносно органів, а також визначені параметри довжини і ширини, абсолютної та відносної маси. Визначено, що топографія сел...

The article presents the results of research on the productivity of rabbits of different genotypes (growth and development, slaughter and meat indicators, fur productivity); a comprehensive evaluation of the productivity of rabbits in the process of industrial hybridization was carried out. The following research methods were used in the work: zootechnical (productivity, growth and development, reproductive capacity), genetic, biometric (determination of average values and their errors, probabilities of research results). The study was carried out in the FG "Elit" of the Kolomyia district; PE "Western Ukrainian Gardens" of Halytsky District; PP Havrylyuk O. Ya. Bogorodchansky district. The method of pairs of analogues was used in the studies. Their selection took into account genotype, sex, age, live weight, origin, physiological state, lactation period, fertility, productivity (reproduction of female rabbits, fattening and slaughter indicators, etc.). Analogous animals in different groups had maximum similarity, and some differences were allowed within the group. The productivity of female rabbits and young rabbits was evaluated according to the index of reproductive qualities of the female rabbit (Luchin, 2004) and the index of comprehensive assessment (PKO) (Luchin, 2005). The received materials of scientific research were processed by the methods of variational statistics according to V.P. Kovalenko et al. (2010). It was established that different variants of crossing the maternal and paternal forms of the three-breed genotype of rabbits 4/8 white giant 3/8 local chinchilla 1/8 Flanders had different effects on the reproductive indicators of female rabbits and subsequent fattening indicators of young rabbits, in particular, average daily growth and waist width. A successful combination of maternal and paternal forms of rabbits (group 2) was revealed, which in the process of industrial hybridization ensured an increase in multifertility by 8.1 head or 2.5 % (р<0.05), high fertility by 64g or 6.25 % (р<0.05), milk yield by 2.8 kg or 7.2 % (p<0.05), nest weight at 35 days old by 13.4 % (p<0.01). The hybrid young obtained from female rabbits of group 2 (IVYAK + 5 %) was characterized by a higher body weight by 43.8 g or 10.3 % (p<0.001) and waist width by 6.15 cm or 12.2 % (p< 0.001) to 3 control groups. The positive result was achieved due to the effective combination of the initial forms, which in turn ensured high productivity of the stock (heterosis) of the final hybrid and its resistance to climatic and technological conditions of keeping.
