EXTERIOR ESTIMATION OF LIMOUSIN BREED COWS FROM DIFFERENT IMPORTS

Y. Gorinov, K. Lidji

Abstract: Is performed phenotypic estimation in exterior dimensions and indexes of body types of cows Limousin breed reared in herds of different import. The study was performed on 61 full record cows reared in five different farms for the period 2008–2015. The taking of exterior dimensions is conduct ed under normal spring calving, 90–150 days after the birth act. Experimental dates were processed by LS analysis in the middle of the software SPSS. It is established highly significant influence (P < 0.001) of different import cows from Limousin breed on indicators heights stook and seat bones, depth of thorax and vertical perimeter croup, where R2 is in the range 0.604÷0.855.
Differences in shoulder height and width croup, athwart body length and thorax perimeter, are mathematically significant (P < 0.01). The estimated differences in exterior indicators show that the Netherlands imports surpass the heights of the body other analogues of 6.5 to 9.5 cm and indicator depth of thorax this difference reached 10.2 cm. It is found a strong influence of imports of the indices body – rangy, upgraded, chest and pelvis-chest (P < 0.001). The volume of body is the highest deterministic indicator (R2 = 0.904). Established dependences in performed analys characterized imports from the Netherlands elongate and fusiform body, well-developed chest.
