Type Traits of Holstein-Friesian and Red-Holstein Cows Raised Together in a Private Farm in Aydın Province

Abstract

This study was aimed at comparing the conformation traits of two different cattle breeds such as Holstein-Friesian (HF) and Red-Holstein (RH) cows raised together in a farm in Aydın, Türkiye. In this study, 102 HF and 19 RH cows in different lactations numbers (LN) forming a total of 121 cows were used. The type traits were determined using Linear Type Traits (LTT) based on 9 points scoring system and non-linear 100 points method. The LTT were composed of body traits such as Stature (St), Chest Width (CW), Body Depth (BD), Rump Angle (RA), Rump Width (RW) and Body Condition Score (BCS); foot and legs traits: Rear Legs Set Angle (RLA), Rear Legs Rear View (RLV), Real Legs Knee Structure (RLS) and Foot Angle (FA); udder traits: Fore Udder Attachment (FUA), Rear Udder Height (RUH), Rear Udder Width (RUW), Central Ligament (CL), Udder Depth (UD), Rear Teat Placement (RTP), Fore Teat Length (FTL) and Mammary Acuity (MA); and according to the non-linear 100 points method: Dairy Strength (DS, 15%), Frame (20%), Foot and Legs (FL, 25%) and Udder (40%). The results of variance analysis showed that no differences between breeds and LN were found in body composite traits while, for Foot and Legs traits, only the RLA was found significant (P
