The research was conducted on 24 ewes of Awasi sheep. The
animal study were divided into 4 groups each includes six ewes.
The first three groups were injected via variant proportions of
BST hormone ( as serial doses 40 mg, 80 mg, and 120 mg)
dail
y for 2 weeks. The fourth group was considered as control
group. It was measured the quantity of morning milk and
measurement of fat and protein and lactose one time every
week. Tissue specimen was taken from udder to study the
changes of secretive vesicles.
This study was done on the records of 564 milk cows
during the period 2004-2007 .Those cows were dismissed
for many reasons and in different ages. The range of
dismissing age is between 3-6 years. The ratio of
dismissing of those cows was between
20-25% . The rate
of dismissing was high in the first lactation season . It
reached 27,43% for the years 2004-2005, and 24,45% for
the years 2006-2007. The highest percentage of dismissing
was in the first month of milk seasons .It reached 34,49%
in the years 2006-2007.
The aim of this study was to evaluate the affecting factors of
Buffalo milk production in Al- Ghab Plain. The data were
collected according to the farmers during the season of 2009-2010.
The effect of parturition season, dry period and calving int
erval
were studied. The results showed that the mean milk production
was 934,96 kg with 8.1% fat and 4.85% protein. The lactation
period was 180-240 days, the dry period was 120-180 days and the calving interval mean was 420 days. Our results indicated that the quantity of buffalo milk in Syria was low because of the short
lactation period, the long dry period and the long calving interval.
But it could be possible to improve the buffalo milk production by
the better rasing conditions and genetic improvement.
A research had been made in three areas at the Syrian Cost where Al Awassi race is
grown; these areas are (Arab Al Mulk, Dwer Al Khateeb, Bekhdarmow). The number of
Al Awassi there reaches to (439) heads. The research was started at 2/11/2009, and
a
random sample of (82)was selected from each area (33-27-22) in a row, and measured
were at the day number (30-90-150) during the season milking, and completed at 4/3/2010.
Results showed at the second phase of day (90) a high measurements of udder which
meets the maximum standards of milk production, and the udder specification had a
significant impact on all forms of the mammary gland (20,01), as well as the nipple
specification, order of milking season, and age had impact on the nipple's size (20,01), but
not on the length of it, but the season milking and age had effect on udder height above the
ground (20,001).
Results showed a correlation which is not fixed between the udder specifications and
quantity of milk as well as a weak and positive relationship between the amount of milk
and nipple measurements in the order of (r=0.33, r=0.49, r=0.19, r=0.27).
This study was carried out using white German goat race during 2000-2001
at the Research Center of Animal Production Division, Humboldt University,
Berlin, in order to examine the validity of the Lactocorder instrument, which
has been used for det
ermination of milking curve of cows, to determine the
milking curve of goat, and to study the timing changes of this curve.
