Abstract
The feed processing used on non ruminant animals like pigs and poultry is one of the most studied field. Pig production in Albania is extensive and hygiene conditions in pig stalls are too far from the usually standards. The main objective of this study was to investigate the effects of pellet and meal feed on the performance parameters like as body live weight (BLW), daily weight gain (DWG) and feed conversion ration (FCR) of pigs, under consideration of the extensive pig production conditions like these in Albanian livestock farms. The utilization of pelleted feed improved growth parameters, average live weight (kg), daily weight gain g/day and feed conversion ratio (FCR), compared to the control group. During the experimental period, the group treated with pellet feed had a higher average live weight, 1.3%, 2.4%, and 2.7% respectively on the third, fifth and seventh week. The average daily weight gain had the same tendency. The pellet feed improved clearly the feed conversion ratio also. Based on the achieved results in the present investigations, it could be concluded that the utilization of pelleted feed led to an improvement of the production parameters in pigs, especially under the extremely extensive farm conditions like these in Albanian farms of pig production.

Key words: pigs, pellet feed, granulated feed, performance parameters, daily weight gain

Rezumat
Fabricarea nutreturilor destinate animalelor nerumegatoare, suine si pasari, este unul din cele mai investigate domenii. Cresterea porcilor în Albania se realizeaza, în mare parte în sistem extensiv, iar conditiile igienice ale adaposturilor sunt destul de departe de cerintele standard. Principalul scop al acestui studiu a fost de a investiga efectele utilizarii hranei peletate si sub forma de faina asupra performantelor productive ale porcilor, ca de exemplu greutatea vie (GV), sporul mediu zilnic (SMZ) si indicele de conversie a hranei (ICH), în conditii extensive de productie. Utilizarea nutretului sub forma de pelete a îmbunatatit rezultatele legate de crestere, greutatea vie medie (kg), sporul mediu zilnic si conversia hranei, comparative cu lotul de control. Astfel, pe parcursul cercetarilor, greutatea vie a porcilor din lotul hranit cu nutret peletat a prezentat valori superioare pentru greutatea corporala medie, cu 1,3%, 2,4% si 2.7%, în saptamânile experimentale trei, cinci si sapte. Sporul mediu zilnic a urmarit aceeasi dinamica. Hrana sub forma de pelete a îmbunatatit de asemenea si conversia hranei. În consecinta, utilizarea nutretului combinat peletat a condus la îmbunatatirea parametrilor productivi ai purceilor, în conditiile tehnologice asigurate de fermele de suine de tip extensiv din Albania.
