Vpliv dokrmljevanja s slamo ali senom na etološke in pitovne lastnosti ter mesnatost prašičev pitancev : diplomsko delo : univerzitetni študij = Influence of enrichment of environment with straw or hay on ethological and fattening traits and carcass composition of fattening pigs : graduation thesis : university studies
Hrastar, Kristijan
Prašiči v skupinskih boksih z rešetkastimi tlemi nimajo drugega materiala za zaposlitev kot krmno mešanico, zato lahko dodatek slame ali sena zanje pomeni tudi obogatitev okokja. V raziskavi na 192 ...prašičih pitancih (polovica ženskega spola in polovica mošlih kastratov) od 60 kg žive mase do zakola pri povprečni telesni masi 96 kg smo želeli preučiti vpliv dokrmljevanja s slamo ali senom na obnašanje živali, prirast in mesnatost. Dodatek slame ali sena je zmanjšal aktivnost zauživanja poplne krmne mešanice v času opazovanj med 6.00 in 14.00 uro. Prašiči z dodatkom so več krmne mešanice zaužili po koncu opazovanja. Ukvarjanje s slamo ali senom je skrajšalo trajanje mirovanja. Ugotovili smo tudi, da so prašiči, ki so lahko žvečili slamo ali seno bistvenomanj pogosto žvečili palice v pregradah boksov. Dodatek slame ali senaje prav tako močno zmanjšal agresivnost med prašiči pitanci. Dodatek slameali sena ni vplival na prirast in mesnatost prašičev pitancev. Seno je bilo med prašiči pitanci bolj priljubljeno, saj so ga raje žvečili in žrli kot slamo.
