The evolution of milk production was studied in the country for the period
1994-2008 by measuring the role of horizontal and vertical expansion factors.
Results showed that:- Horizontal expansion factors played the main role in
determining the dev
elopment trends of milk production in the country during
the studied period, and that not in accordance with global trends in this area, so
that 98% of the changes in production were interpreted by the changes in the
numbers of cattle and 87% of the increase in production achieved Due to a rise
in the numbers of cattle, which increased by 4.5% annually, while the
intensification of production factors contribute only about 13% of the increase
in production. - The policy for changing the structural composition of the herd
of cattle by type and which was based on the reduction of the proportion of
cows low-productivity local cattle and focus on raising the proportion of cows
improved in the herd had positive results, however, that these results came very
modest, and did not lead to a substantial increase in annual production for
cows during the period studied only by 0.7% only.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
The aim of this study was to investigate the specific antibodies
and to determine the seroprevalence of Chlamydophila abortus on
abortive cows in north area in Syria.
Blood samples were collected and analyzed from 41 cows,
aborted at least once, taken from 316 cows suspected from eight
herds in north region of Syria.
