Effects of multiphase nutrition during the starter period on production performances of broilers
Efekti multifazne ishrane u starter periodu na proizvodne performanse brojlera
Abstract
The objective of the present study was to investigate the effect of multiphase nutrition, i.e. different mixtures used in broiler nutrition, whose protein content was reduced in several phases, on production performances of broilers. The study was performed on 1216 individually tagged chickens of the Ross 308 strain, separated by sex, and divided into four groups. The standard fattening technology, with four nutrition treatments, was applied during the trial period (1-21 days). Chickens of the first group (control) were fed diet containing 23% of proteins from the 1st to 21st day, while the protein content in the remaining three trial groups was reduced during the trial period in several phases. Based on processed data it can be concluded that different programmes of multiphase nutrition had resulted in different effects on production performances of male and female chickens. Multiphase nutrition at the end of the starter period (21st day) had no statistically significant effect on a b...ody weight of male and female chickens, i.e. the reduction of the protein level in mixtures for broilers had no effect on the decrease of the body weight compared to control male (723.48 g) and female (680.66 g) chickens. At the same time, programmes of multiphase nutrition (T4) resulted in the most favourable feed conversion in male (1.468) and female (1.502) chickens, which is in favour of the application of multiphase nutrition, considering that the difference in feed conversion can be essential for accomplishing positive economical results in the production. .
Cilj istraživanja je bio da se ispita uticaj multifazne ishrane, odnosno uticaj različitih smeša za ishranu brojlera u kojima je sadržaj proteina smanjen višefazno, na proizvodne osobine tovnih pilića. Ispitivanje je izvedeno na 1216 individualno obeleženih pilića, provenijence Ross 308, razdvojenih po polu, podeljenih u četiri grupe. U oglednom periodu (1-21 dan) primenjena je standardna tehnologija tova, sa četiri tretmana ishrane. Pilići prve grupe (kontrolne) hranjeni su smešom sa 23% proteina u trajanju od 1. do 21. dana, a ostalim trima grupama sadržaj proteina je tokom oglednog perioda smanjen višefazno. Na osnovu obrađenih podataka može se konstatovati da su različiti programi multifazne ishrane rezultirali različitim efektima na proizvodne performanse pilića muškog i ženskog pola. Multifazna ishrana na kraju starter perioda (21 dan) nije statistički značajno uticala na telesnu masu pilića muškog i ženskog pola, odnosno smanjenje nivoa proteina u smešama za ishranu brojlera nij...e uticalo na smanjenje telesne mase u poređenju sa kontrolnom grupom pilića muškog (723,48 g) i ženskog (680,66 g) pola. Istovremeno, program multifazne ishrane (T4) rezultirao je najpovoljnijom konverzijom hrane kod pilića muškog (1,468) i ženskog (1,502) pola, što ide u prilog primeni multifazne ishrane, s obzirom da razlika u konverziji hrane može biti ključna za ostvarenje pozitivnog ekonomskog efekta proizvodnje. .
