Использование Питательных Веществ Баранчиками Разного Генотипа

The paper presents the results of a comparative study of feed nutrient utilization in buck lambs with different genotypes under the same growth and management conditions. It has been established that the crossbred and purebred buck lambs have a substantial difference in digestibility of dry and organic matter, as well as protein and fiber. Differences in digestibility of nitrogen-free extractive substances are smaller, although they are significant. Hybrids born to ewes of meat-wool type are superior in terms of feed utilization efficiency in comparison to lambs born to ewes of wool-meat type. The nitrogen balance is also higher in the hybrids. The differences between purebred lambs and hybrids born to ewes of meat-wool type are as follows: hybrids with the Romney Marsh breed – 1.16 g, hybrids with the Kuibyshev breed – 0.1 g. A similar trend is observed for the balance of calcium and phosphorus.El artículo presenta los resultados de un estudio comparativo de la utilización de nutrientes en corderos con diferentes genotipos en las mismas condiciones de crecimiento y manejo. Se ha establecido que los corderos cruzados y de raza pura tienen una diferencia sustancial en la digestibilidad de la materia seca y orgánica, así como de las proteínas y la fibra. Las diferencias en la digestibilidad de las sustancias extractivas sin nitrógeno son más pequeñas, aunque son significativas. Los híbridos nacidos de ovejas del tipo carne-lana son superiores en términos de eficiencia de utilización de alimento en comparación con los corderos nacidos de ovejas del tipo carne-lana. El balance de nitrógeno también es mayor en los híbridos. Las diferencias entre los corderos de raza pura y los híbridos nacidos de ovejas del tipo lana de carne son los siguientes: híbridos con la raza Romney Marsh - 1.16 g, híbridos con la raza Kuibyshev - 0.1 g. Se observa una tendencia similar para el equilibrio de calcio y fósforo.в статье представлены данные по сравнительному изучению использования питательных веществ корма баранчиками разного генотипа в одинаковых условиях вы-ращивания и содержания. Установлено, что у помесных и чистопородных баранчиков наблюдалась значительная разница по переваримости сухого и органического вещества, протеина и клетчатки. По переваримости БЭВ полученные различия менее значительные, хотя и достоверные. При этом следует отметить превосходство помесей, полученных от овцематок мясошерстного типа по эффективности использования кормов по сравнению со сверстниками, полученными от шерстномясных маток. Баланс азота оказался выше также у помесей. При сравнении с чистопородными сверстниками разница у варианта с ромни-марш составила 1,16г, а у варианта с куйбышевской - 0,1г у мясошерстных маток. Аналогичная тенденция и по балансу кальция и фосфора

Biomechanical aspects of researches of degenerative-dystrophic diseases of lumbar segment of spine and hip joints (the review of literature)

Degenerative dystrophic diseases of spine and hip joints are considered by the most of the authors as united pathogenic process. The common and connecting element is change of spatial orientation of spine with redistribution of loads on hip joints and sacroiliac articulations, i.e. disorder of topographic-anatomic interrelations of bone-joint formations of "Chacklin triada". For objectification of estimation offunctional disorders of locomotor system biomechanical methods are widely used in clinical practice, the most informative of them is study of locomotions. In spite of achievements in studying of individual degenerative-dystrophic affections of locomotor system there is no single solution of the problem of combined diseases of hip joints and lumbar segment of spine and their mutual influence that determines actuality of further study

Experience of treatment of patients with intervertebral hernias on lumbar level

The article is devoted to the analysis of the results of examination and treatment of patients with spine pathology in lumbar segment. The data on the actuality of the problem of spine pathology (frequency of occurrence, invalidization). On the basis of their experience the authors propose complex approach to the treatment of patients with discogenic lumbar-sacral rediculitis, complicated by the disks hernias and pain syndrome, based on the definite algorithm in the form of treatment program. Lumbodynia and lumbar ischialgia prevailed in neurological status of the patients (45,2 %). Radicular disorders (radiculopathy, radiculoneuritis) are registered in 13,1 % of patients. Pain syndrome by the visually analogue scale corresponded to 7-6 (40 % of patients) and 5-4 points (60 % of patients). Protrusion of the disks (bulging of the disk up to 4 mm) are revealed in 24,3 % of cases. Median and paramedian hernias of disks (bulging of the disk from 4 to 8 mm) are revealed in 57,4 % patients. Posterolateral hernias of disks (bulging of the disk from 4 to 7 mm) are revealed in 18,3 % of patients. At the estimation of the effectiveness of treatment of 115 patients favorable results of treatment in the terms up to 1 year were registered in 99 of them
