Fenotipske lastnosti ovc kot pokazatelj pasemske pripadnosti

Lakovšek, Ana (author), Simčič, Mojca (mentor)

Namen diplomske naloge je bil izmeriti telesne mere in pridobiti telesno maso ter opisati lastnosti zunanjosti ovnov jezersko-solčavske in oplemenjene jezersko-solčavske pasme. Meritve smo opravili pri skupno 88 ovnih julija 2020 na testni postaji za ovne na PRC Logatec. V času zaključevanja direktnega testa smo izmerili 45 ovnov jezerskosolčavske in 43 ovnov oplemenjene jezersko-solčavske pasme. Merili smo višino vihra, dolžino telesa, obseg prsi, dolžino repa in dolžino ušes. Poleg tega smo še opisali dolžino repa glede na skočni sklep, postavitev ušes, barvo volne, oznake na glavi in rogatost. Na podlagi izmerjenih telesnih mer smo izračunali morfometrične indekse pri živalih, in sicer indeks telesnega okvirja oz. indeks dolžine (ITO), indeks razvitosti prsnega koša (IRPK), indeks konformacije (IK) in indeks telesne mase (ITM). Višina vihra izmerjenih ovnov jezersko-solčavske pasme (JS) je bila 55,74 cm, ovnov oplemenjene jezerskosolčavske pasme(JSR) pa 53,10cm. Dolžina trupa od vihra do sednice je bila 67,97 cm (JS) in 66,41 (JSR), obseg prsi 79,57 cm (JS) in 81,22 cm (JSR), dolžina repa 44,17 cm (JS) in 28,54 cm (JSR), dolžina ušes pa je bila 14,74 cm (JS) in 12,51 cm (JSR). Indeks telesnega okvirja izmerjenih živali je bil 122,09 (JS) in 125,30 (JSR), indeks razvitosti prsnega koša 143,04 (JS) in 153,34 (JSR), indeks konformacije 113,87 (JS) in 124,67 (JSR) in indeks telesne mase 88,00 (JS) in 92,69 (JSR). Kot smo pričakovali so bili JSR ovni manjši od JS ovnov in so imeli krajši rep ter krajša ušesa, imeli pa so večji obseg prsi in večji indeks razvitosti prsnega koša ter indeks telesne mase od JS ovnov.

Abstract

The aim of the work was to measure the body measurements, body weight and describe the type traits of rams of the Jezersko-Solčava breed and the Improved Jezersko-Solčava breed. The measurements were performed on a total of 88 rams in July 2020 at the PRC Logatec ram test station. We measured 45 rams of the Jezersko-Solčava breed and 43 rams of the Improved Jezersko-Solcava breed at the time of completion of the direct test. We measured wither height, body length, chest girth, tail length and ear length. In addition, we described tail length in relation to the hock joint, ear position, wool colour, head markings, and horns. Based on the body measurements, we calculated morphometric indices for the animals, namely: index of body frame or index of length (ITO), index of thorax development (IRPK), index of conformation (IK) and index of body weight (ITM). The wither height of the measured rams of the Jezersko-Solčava breed (JS) was 55.74 cm and that of the rams of the Improved Jezersko-Solčava breed (JSR) was 53.10 cm. Body length from withers to ischium was 67.97 cm (JS) and 66.41 cm (JSR), chest girth 79.57 cm (JS) and 81.22 cm (JSR), tail length 44.17 cm (JS) and 28.54 cm (JSR), and ear length 14.74 cm (JS) and 12.51 cm (JSR). The index of body frame was 122.09 (JS) and 125.30 (JSR), the index of thorax development was 143.04 (JS) and 153.34 (JSR), the index of conformation was 113.87 (JS) and 124.67 (JSR) and the index of body weight was 88.00 (JS) and 92.69 (JSR). As expected, JSR rams were larger than JS rams and had shorter tails and ears, but they had larger chest girth and higher chest development index and body weight index than JS rams.
