Variation of Microbial Load of Sudanese Nubian Goat’ Milk as Affected by Lactoperoxidase Enzyme System, Stage of Lactation and Storage Temperature
H.M.I. Mohamed, I.E.M. El Zubeir and A.A. Fadlelmoula

Abstract:
This study was carried out to improve the keeping quality and to prolong the shelf life of milk of Sudanese Nubian goat at different stages of lactation and storage temperatures (5±2, 13±2, 25±2 and 37±2°C) by using Lactoperoxidase Enzyme System (LPS). Morning milk samples (36 samples) were collected from Nubian goat unit of the Faculty of Animal Production University of Khartoum during February to November, 2009. The result showed that the treated LPS milk samples were significantly (p≤0.05) affected by the addition of the enzyme, stages of lactation and storage temperature. Moreover, the study showed reduction in total viable bacterial count, coliform, psychrotrophic bacteria and yeast and mould content of treated samples with the reducing of degrees of temperature compared with the control samples kept under the same condition. Samples kept at 37±2°C showed higher microbial load and shorter shelf life compared with that stored at 5±2°C. It was concluded that application of the LPS inhibited the growth and multiplication of microorganisms and prolonged the shelf life of goat’s milk under Sudan condition.
