Effects of Different Management Practices on Milk Hygiene of Goat Farms in Khartoum State, Sudan
M.E.M. Abdalla and E.M. El Ibtisam Zubeir

Abstract:
This study was carried out to evaluate the procedures and management practices and their effect on milk microbiological quality in 15 cross dairy goat farms that distributed in Khartoum State. The areas of study include Kuku, Alhatana, Aldroshab, Alkadrow, Shambat and Ombada. The information were collected through field visits and questionnaire, moreover seventy five raw bulk milk samples were collected from those farms. One duplicate sample per month from each farm were collected and examined for total bacterial counts, coliform counts, yeast and mould counts, milk acidity and freezing point. The questionnaire showed that the dominant breed for crossing was Saanen breed (100%) with blood percentage which vary from 50-90% and it was observed that the well designed housing was dominant in the studied farms and there was a high level of education for the goat owners, since more than 50% awarded a university degree. The laboratory examination of the milk samples revealed that the total bacterial counts were 762x106±2.14, 1423x106 and 702x105 cfu mL-1 for mean±standard deviation, maximum and minimum values, respectively. The coliform bacteria counts revealed 636x105±1.66, 1204x106 and 652x105 cfu mL-1, respectively. Similarly the average yeast and mould counts were 51x105±3.63, 160x105 and 30x104 cfu mL-1. Acidity was found to be 0.231±.0026, 0.279 and 0.185%, while the freezing point were -0.484±0.032, -0.443 and 0.576°C, respectively. The present result also showed that there were significant (p<0.01) positive correlations between total bacterial counts and each of coliform counts (r = 0.470) and acidity (r = 0.808). Similarly significant positive (p<0.01) correlation between coliform counts and acidity (r = 0.613) and significant (p<0.05) correlation between yeast and mould counts and freezing point (r = 0.283) were estimated.
