Correlation between productive and interior traits of steers of different genotypes

ABSTRACT The objective was to study the productive and biological traits of young cattle of the Kalmyk breed and its crosses. The experiment was conducted on 4 groups of steers, 10 heads each, at OAO Shurupovskoe, Frolovsky District, Volgograd Region. The experimental steers were kept in rooms separ...

Description
Summary:ABSTRACT The objective was to study the productive and biological traits of young cattle of the Kalmyk breed and its crosses. The experiment was conducted on 4 groups of steers, 10 heads each, at OAO Shurupovskoe, Frolovsky District, Volgograd Region. The experimental steers were kept in rooms separately in groups on a deep bed of straw and had free access to walking yards with mounds. The hemoglobin content and the numbers of erythrocytes and leukocytes were determined on a Medonic CA 530 hematological analyzer. The total protein in blood serum and protein fractions were found on an automatic biochemical analyzer Stat Faks 1904. The digital experimental data were processed by the variation statistics method in terms of the significance of the compared parameters using the Student's test accepted in biology and animal science. The study evidenced that the contents of morphological elements and proteins in blood reflected the metabolism and potential for crossbred steers to gain muscle mass. RESUMO O objetivo era estudar os traços produtivos e biológicos do gado jovem da raça Kalmyk e seus cruzamentos. A experiência foi conduzida em 4 grupos de bois, 10 cabeças cada, na OAO Shurupovskoe, Distrito de Frolovsky, Região de Volgograd. Os bois experimentais foram mantidos em quartos separados em grupos em uma cama de palha profunda e tiveram livre acesso a pátios de caminhada com montes. O conteúdo de hemoglobina e o número de eritrócitos e leucócitos foram determinados em um analisador hematológico Medonic CA 530. A proteína total em soro sanguíneo e frações proteicas foram encontradas em um analisador bioquímico automático Stat Faks 1904. Os dados experimentais digitais foram processados pelo método de estatística de variação em termos da significância dos parâmetros comparados usando o teste de Student aceito em biologia e ciência animal. O estudo evidenciou que o conteúdo de elementos morfológicos e proteínas no sangue refletia o metabolismo e o potencial de bois cruzados para ganhar massa muscular.
