Zavod za specijalno stočarstvo Agronomskog fakulteta Sveučilišta u Zagrebu i Hrvatski stočarski centar nositelji su projekta kojemu je cilj genetsko definiranje i utvrđivanje vanjštine hrvatskih izvornih pasmina ovaca. Za tu su namjenu izvršene komisijske ocjene vanjštine paških ovaca i uzete tjelesne mjere od ukupno 379 grla iz 4 stada u vlasništvu obiteljskih gospodarstava koja se tradicionalno bave ovčarstvom na otoku Pagu. Ovce su bile različite dobi, spola i uzrasta. Nakon pojedinačnih procjena dobi po zubima i utvrđivanja spola, sva su grla podijeljena u sljedeće skupine: 1. šilježice prosječne dobi oko 15 mjeseci; 2. mlade ovce u dobi između 2 i 3,5 godine; 3. odrasle ovce u dobi iznad 3,5 godine; 4. ovnovi. Prosječna visina grebena odraslih ovaca iznosila je 56,14 cm, dužina trupa 64,27 cm, širina prsa 17,11 cm, dubina prsa 28,98 cm, opseg prsa 83,26 cm, opseg cjevanice 7,04 cm i tjelesna masa 43,05 kg. Utvrđeno je da današnje paške ovce imaju veći tjelesni okvir i tjelesnu masu u odnosu na ranija istraživanja (prije 50 i više godina). Šilježice su imale u prosjeku 99,86% visine grebena i 98,63% dužine trupa odraslih ovaca, te 79,65% završne tjelesne mase. Utvrđen je značajan utjecaj spola na tjelesni okvir, te su ovnovi bili znatno razvijeniji u odnosu na ovce.Department of Animal Science at the Faculty of Agronomy, University of Zagreb and Croatian Livestock Centre are conducting a project whose basic purpose is to determine genetic and exterior characteristics of Croatian autochthonous sheep breeds. For that purpose, the exterior of the Pag sheep was evaluated by a commission and body measurements were taken from 379 heads from 4 flocks. The flocks are owned by local people with long tradition in sheep breeding on the island of Pag. The sheep were of different age, sese and stature. After determining the age according to the teeth and sese by visual assessment, the following groups of sheep were formed: 1) ewe hoggets about 15 months old; 2) young sheep between 2 and 3.5 years old; 3) older than 3.5-year-old adult sheep; 4) adult rams. The mean height of crest of adult sheep was 56.14 cm, the length of the trunk 64.27 cm, the width of the chest was 17.11 cm, the depth of the chest 28.98 cm, the circumference of the chest was 83.26 cm, the circumference of the leg was 7.04 cm and the body weight was 43.05 kg. Ewe hoggets had 99.86% of adult sheep height of withers, 98.63% of adult sheep length of the trunk and 79.65% of their terminal body weight. It was determined that sex had a significant influence on trunk conformation and the rams were considerably bigger than ewes
