Abstract
Aim of this research was to determine the influence of lactation order on fertility, milk yield and Sanska goat milk chemical composition. Monitoring of mentioned parameters was conducted from first till third lactation. It has been concluded that from first till third lambing fertility was increasing. In first lactation goats produced significantly (P lt 0,01) less milk (561,13 kg), than goats in second (654,25 kg) and third (743,20 kg) lactation. Amount of milk fat and proteins was increasing from first till third lactation. Research has shown that lactation order, goat age has significant influence on fertility, milk yield and milk chemical composition.
Cilj ovog istraživanja je bio utvrditi uticaj redosleda laktacija na plodnost, proizvodnju i hemijski sastav kozjeg mleka. Ukupno je praćeno 136 koza sanske rase, kroz tri uzastopna jarenja i prve tri laktacije. Plodnost se povećavala od prvog do trećeg jarenja i veća je bila posle trećeg partusa za 8,57% u odnosu na prvo jarenje. Koze su u prvoj laktaciji proizvele vrlo značajno (P lt 0,01) manje mleka (561,13 kg) od koza u drugoj (654,25 kg) i trećoj laktaciji (743,20 kg). Sadržaj mlečne masti i proteina u mleku značajno se povećavao od prve do treće laktacije. Rezultati istraživanja pokazuju da redosled laktacija odnosno uzrast koza imaju značajan uticaj na plodnost, količinu mleka i delimično na hemijski sastav mleka.
