Bu araştırma, Malatya Sultansuyu Tarım İşletmesi'ndeki toplam 99 baş Esmer ırkı inekte linear tip özelliklerini (LTÖ) ve bunlar üzerine bazı çevre faktörlerinin etkilerini belirlemek amacıyla yapılmıştır. Araştırmada, laktasyon sayısının LTÖ'nden; sağrı meyili, ön meme başı yerleşimi ve meme derinliği, puanlama mevsiminin; ön meme başı yerleşimi, sağrı genişliği, arka meme yüksekliği, ayak yapısı, meme derinliği ve arka bacaklar, puanlama yılının; sütçü form ve sağrı genişliği, yaşın ise vücut derinliği, sağrı genişliği, sütçü form, ön meme bağlantısı, meme derinliği, ön meme başı uzunluğu ve suspansor ligament özellikleri üzerine etkisi istatistiki olarak önemli (p

The aim of this study was to determine linear type traits (LTT) and the effects of some environmental factors on LTT of Brown-Swiss cows bred at Malatya Sultansuyu Agricultural Station. In this study, the number of lactation had significant influence on pelvic angle, front teat placement and on udder depth. The grading season influenced front teat placement, pelvic width, rear udder height, foot shape, uider depth and on rear legs. The effects of grading year on dairy form, and pelvic width was statistically significant. The influence of age on body depth, pelvic width, dairy form, front udder attachment, udder depth, front teat length and on suspensory ligament were significant. The level of significance in the above measurements varied between p<0.05 andp<0.00l. Grades on LTT varied significantly depending upon lactation stages. Adjusted avarage grade points for LTT was 13.25 ± 0.58 for stature and 36.48 ± 0.56 for the front teat length. In contusion, Brown-Swiss cows bred in Agricultural Station had small satature, poor rear udder attachment and tall front teats. The influence of lactation stage were generally significant on LTT. These evaluations might be stated that in grading of cows, stage of lactation can be taken into consideration.
