Mahaliy sigirlarni Limuzin zotli buqalar bilan çatiştirişdan olingan birinçi böğin (F1) duragay buqaçalarning eksteryer körsatkiçlari

Abstract

This article investigates the exterior traits and body conformation indices of first-generation (F1) crossbred bulls produced by crossing local cows with Limousin beef bulls. The study was conducted in 2025–2026 at the Pişembay çorva farm in Kegeyli District, the Republic of Karakalpakstan. Two groups were compared: local bulls and crossbred bulls with a ½ Limousin × ½ local genotype, with 10 animals in each group. Body measurements at birth and at six months of age were evaluated. At six months, the crossbred bulls showed higher values for several exterior traits, including withers height, rump height, chest depth, chest circumference, chest width, and oblique body length, compared with their local counterparts. The crossbred animals also demonstrated higher values for chest development, pelvic-chest, compactness, and meat conformation indices. These findings contribute to the assessment of the effects of Limousin crossbreeding on body development and exterior characteristics of young cattle under local production conditions.
