This study was conducted to study the effect of including
different levels of Grape seed oil as a natural antioxidant on
layer hen egg production, egg quality,.
The research aims to productive performance of the laboratory
evaluation of (ammonia, urea) of the General Fertilizers Company
during the period 2001-2010 using multivariate analysis (factor
analysis). Researcher inductive approach adopted in the
study of the
basic variables affecting the productive performance, which allows the
use of data from the reality of the actual production, and strengthening
the means of observation and viewing during the production process so
as to detect and reasoning on the efficiency and effectiveness of the
productive performance through causal relationships between the various
factors to arrive at check results research goals.
This study was conducted at the Deir Al-Hajar Shami Cattle Research
Station, Animal Wealth Research Administration. For this purpose 12
primiparous Shami cows were used to know the influence of the milking
regimes in the production performance of
the cow and the composition of the
produced milk. The animals were divided randomly into two equal groups.
Machine milking were used at the first group in the presence of the calf, or for
the machine milking without the presence of the calf at the second group.
The daily production of milk was estimated weekly from every cow in both
groups and at the same time milk samples were taken to estimate the
percentage of the basic components of milk such as fat, protein, lactose and dry
matter until the end of lactation. Data were analyzed in statistical program SAS
by using variance analysis ANOVA (Mixed Model).
