Abstract:V letu 2010 smo izvajali poskus z napajanjem telet na dveh kmetijah. Na kmetiji A, kjer redijo teleta lisaste pasme, smo z mlečnim nadomestkom teleta hranili s pomočjo vedra na cucelj. Na kmetiji B, kjer redijo teleta črno-bele pasme, je bil za krmljenje telet z mlečnim nadomestkom uporabljen avtomat za napajanje. Skupno smo v poskusu spremljali 20 telet od rojstva do starosti 10 tednov. Teleta smo v poskusnem obdobju petkrat (1., 8., 29., 50. in 71. dan) stehtali ter izmerili višino vihra, višino križa in dolžino telesa. Želeli smo ugotoviti, kateri način hranjenja je primernejši z vidika živali kot tudi z vidika delovne zahtevnosti za rejca. Primerjava krmljenja telet z vedrom in avtomatom za napajanje je pokazala statistično značilne razlike (p < 0,05) v telesni masi v obdobju med 50. in 71. dnem starosti (13,30 kg oziroma 9,90 kg), v višini vihra v obdobju med 8. in 29. dnem starosti (1,80 cm oziroma 2,70 cm), v višini križa v obdobju med 29. in 50. dnem starosti (1,70 cm oziroma 2,70 cm) ter statistično značilne razlike (p ≤ 0,001) v dolžini telesa v obdobju med 50. in 71. dnem starosti (2,80 cm oziroma 1,50 cm). Avtomatsko napajanje se je izkazalo primernejše za kmetije z večjim številom telet, saj prihranimo veliko delovnih ur.

Title:Comparison between classic and automatic system for feeding calves
Abstract:In 2010, we studied different feeding strategies for calves on two farms. On the first farm “A”, calves of Simmental breed were fed with milk replacer using a bucket teat (classical feeding). On the second farm “B” calves of Holstein-Friesian breed were given milk replacer using an automatic milk feeding. The experiment comprised 20 calves which were monitored from birth until the age of 10 weeks. On specific days (1st, 8th, 29th, 50th and 71st) calves were weighed and their withers height, back height and body length were measured. The aim of our study was to find out which feeding strategy is more suitable for the calves and for the farmer. The comparison between feeding using bucket teat or automatic feeding system showed significant differences (p < 0.05) in the body weight during the period between 50th and 71st day of age (13.30 kg and 9.90 kg, respectively), in withers height in the period between 8th and 29th day of age (1.80 cm and 2.70 cm, respectively) and in back height in the period between 29th and 50th day of age (1.70 cm and 2.70 cm, respectively). Significant differences were also seen (p ≤ 0.001) in body length during the period between 50th and 71st day of age (2.80 cm and 1.50 cm, respectively). The study proved automatic feeding to be more suitable for farms with large number of calves as it could substantially reduce working hours.
