PHENOTYPIC EXPRESSION OF FATTENING YOUNG BOARS OF THE LARGE WHITE IN PERFORMANCE TEST

Ukupno 255 nerastića iz četiri linije nerastova velikog jorkšira ispitano je performance testom od 28 do 101 kg tjelesne mase. Nerastići su hranjeni ad libitum. Tijekom ispitivanja od 84 dana, nerastići su u prosječnoj dobi od 170,24 dana ostvarili prosječni dnevni prirast od 0,865 kg, konverziju hrane od 2,51 kg i debljinu leđne slanine od 14,08 mm. Utvrđena je statistički značajna fenotipska povezanost (r) relevantnih pokazatelja tovnosti nerastića (dnevni prirast : konverzija hrane = 0,350**; dnevni prirast : ukupna količina hrane = -0,380**; konverzija hrane : debljina slanine = 0,240**; konverzija hrane : ukupna količina hrane = 0,745**; konverzija hrane : dnevna konzumacija hrane = 0,450**).A total ad 255 young boars from four lines of the Large White was investigated by performance test from 28 to 101 kg of body weight. Young boars were fed ad libitum. During the 84-day research young boars aged 170.24 days on average realized average daily gain of 0.865 kg, food conversion of 2.51 kg and back fat thickness of 14.08 mm. Statistically significant phenotypic corelation was determined (r) among relevant indicators of young boars fattening capacity (daily gain : food conversion = 0.350**; daily gain : total food intake = - 0.380**; food conversion : fat thickness = 0.240**; food conversion : total food quantity = 0.745**; food conversion : daily food consumption = 0.450**)
