Abstract


The aim of the study was to research milk yield, composition and hygienic quality of routinely produced milk from Lipizzan mares. It was the first known case of adapting mares of this breed to the routine machine milking procedure. Three Lipizzan mares included in the routine machine milking produced commercial quantities of mare’s milk. Milk from Lipizzan horse breed was for the first time obtained and analysed in such quantity. The mares were milked consecutively three times per day during five days in a week, and during weekends, they were joined with their foals. The average values were as follows: daily milk yield (MY) was 8.24 kg, fat content (FC) was 4.027 g/kg, protein content (PC) was 15.064 g/kg, lactose content (LC) was 63.218 g/kg, somatic cell count (SCC) was 6.556 x 10³/ml, total bacteria count (TBC) was 114.689 x 10³/ml, and average freezing point (FP) was -0.505 °C. Consecutive milking significantly influenced PC, LC, SCC, and TBC. FC tended to increase with days in milk, whereas PC, SCC, and TBC decreased during the lactation stage. Significant differences between mares were found in PC, LC, SSC and TBC. Interaction between consecutive milking and mare was significant only for FC. The study confirmed that warmblooded horse breed can be used for commercial milk production along with coldblooded breeds. Routine machine milk production with use of Lipizzan mares could add an economic value to the indigenous breed and serve as an additional reason for its preservation.

Key words: milk composition; milk yield; days in milk; consecutive milking; hygienic quality

 

KOLIČINA, SESTAVA IN HIGIENSKA KAKOVOST MLEKA PRIDOBLJENEGA Z RUTINSKO STROJNO MOLŽO LIPICANSKIH KOBIL

Povzetek: Pridobili in raziskali smo komercialno koliÄino namolženega mleka kobil lipicanske pasme. Rutinska mehanska molža treh kobil je potekala na raziskovalni ustavnovi, registrirani za prirejo kobiljega mleka. Rezultati so pokazali, da je bila povpreÄna dnevna koliÄina mleka (KM) 8,24 kg, mleko pa je v povpreÄju vsebovalo 4,027 g maÅ¡Äobe/kg, 15,064 g beljakovin/kg in 63,218 g laktoze/kg. PovpreÄno Å¡tevilo somatskih celic v mleku je bilo 6,556 x 10³/ml, povpreÄno skupno Å¡tevilo mikroorganizmov 114,689 x 10³/ml, povpreÄna zmrziÅ¡Äna toÄka (ZT) mleka pa -0,505 °C. Rezultati analize variance so pokazali, da se koliÄina beljakovin in laktoze ter Å¡tevilo somatskih celic in skupno Å¡tevilo mikroorganizmov statistiÄno znaÄilno razlikujejo glede na zaporedno molžo ter med posameznimi kobilami ter da se koliÄina beljakovin, Å¡tevilo somatskih celic in skupno Å¡tevilo mikroorganizmov v mleku zmanjÅ¡uje z napredovanjem laktacije, medtem ko se vsebnost maÅ¡Äob poveÄuje. Interakcija med zaporedno molžo in kobilo je statistiÄno znaÄilno vplivala le na vsebnost maÅ¡Äob. Gre za prvo raziskavo mleka kobil lipicanske pasme, kar omogoÄa nadaljno primerjavo med pasmami. Uporaba kobil te slovenske avtohtone pasme konj za komercialno rutinsko prirejo mleka bi predstavljala njeno dodatno gospodarsko vrednost in s tem razlog za ohranitev.

KljuÄne besede: sestava mleka; koliÄina mleka; stadij laktacije; zaporedna molža; higienska kakovost mleka
