The specific aim of this study was to investigate the effects of of
Methalonic Extract of Fenugreek and Nigella Sativa Seeds on blood
profile in Male Rabbits The experiment was
carried out on(30) of Male rabbits divided into(5) groups (6)
animals of each.
A field experiment was conducted during the two consecutive growing seasons
(2010/2011 and 2011/2012) at Ezra’ Research Station/Deraa/Syria in order to evaluate the
role of some agricultural practices in improving the performance of four wheat vari
eties
(Acsad1105, Acsad1229, Acsad885 and Acsad901) under rainfed conditions. The experiment
was laid according to factorial randomized complete block-split design with three
replications. The mean average of early vigor, flag leaf area, peduncle length and leaf area
index was significantly higher during the first growing season for the wheat variety
(Acsad901) at the first planting date with a nitrogen amount of (150 kgN. Hectar1), and
when nitrogen fertilizers were added twice (1.6-2.5, 53.4cm2, 16.3cm, 1.20 respectively).
The mean average of the same studied aspects, however, was significantly lower during the
second growing season in the case of the variety Acsad855 with regards to the early vigor,
as well as in the case of the variety Acsad1129 in the case of the leaf area Flag at a late
planting date, and without nitrogen fertilizers (3.6 4.5, 3.3 cm, 0.18, 16.6 cm2
respectively). The mean average of the grain yield was significantly higher during the first
growing season for two wheat varieties (Acsad901, Acsad1229) at the first planting date,
nitrogen rate 200 kgN. Ha-1, and when nitrogen fertilizers were added twice (660.4, 631.1
g.m-2 respectively), while it was significantly lower during the second growing season for
the variety Acsad1105, at a late planting date, and without nitrogen fertilizers (127 g.m-2).
Optimizing some important cultural practices helps increasing wheat grain yield by
improving morpho-physiological traits related to yield particularly the size of source
photo synthise (Leaf Area Index, Flag leaf area). The response of astivum wheat variety
was better compared to durum wheat. This shows the importance of improving crop
mangment factors in order to reach the maximum potential yield.
The research study was conducted in Hama Governorate during the
agricultural season of 2010 - 2011 through a stratified random sample of 201
farmers who cultivate irrigated durum wheat in the research area in order to
measure the yield gap, the pr
oductive efficiency divergence among farmers and
to determine the effect of using different amounts of the productive factors in
the production process. It also aimed to determine the contribution level of
these factors in the gap formation, as well as to determine the production phase
in which farmers of the sample stand. Descriptive analysis methodology in
addition to the multiple regression technique were used to estimate production
functions. Results showed a yield gap up to 32.6% between farmers in the first
phase and those who are in the fourth phase. The reason why productivity in
large size farms was higher than in small size farms that the second production
stage, the profitable one occurred in large size farms, while the first production
phase occurred in small economic capacity farms. So, another combination of
the production inputs can be used in order to reach a marginal product value
which equals the price value and to increase the production level plus the
productivity of the farmers in the research area.
The experiment was conducted on 24 brown laying hens at 30
weeks old and were randomly assigned to four groups, each
consisting of six laying hens and put in individual cages stacked in
accordance with the battery system in the unit of poultry fee
d at the
Faculty of Veterinary Medicine, University of Hama, in order to
study the effect of different types of oil and fat on performance,
apparent and true metabolizable energy, and apparent and true fats
digestibility.
This research aims to assess and study the evolution of broiler breeding in Syrian
Arab Republic in general and in Syrian Coast and Lattakia Governorate particularly, in
period between 2003 – 2012, and account of production costs for all stages of
broiler
breeding according and analyze these costs, and economical evaluation of production
broiler by using some economic indicators, and clarifying the impact of crisis in Syria the
process of broiler breeding and production in Lattakia Governorate, by comparing the
prices and costs befor and after the crisis.The research shows the production efficiency for
table chicken breeding in Lattakia Governorate amounted to /1.85/ in year 2010, and /1.20/
in year 2014, while the economic efficiencyreached /1.72/ in year 2010, and /1.09/ in year
2014, the return of capital period was 1.3 years in 2010, then it became 9.8 years in 2014.
The aim of the study was to determine the effect of dietary
supplementation of some organic acids (Propionic acid, butyric
acid,) on the performance and some blood biochemical profile of
quails.
Seventy five (75) one day old unsexed Japanese quai
l chicks were
used in this study and distributed randomly into three treatments per
each treatment (25 chicks) commercial Japanese quail chicks were
used for 42 days..
An experiment was carried out using 120 unsexed chicks of a
commercial broiler breed taken from a hatchery nearby the farm of
the experiment. When the chicks started to hatch the chicks were
collected without the need to complete the operation of
hatching to
ensure that the hatching chicks were hatched at the same time.
The chicks were distributed into four groups of each group divid into 6
sub groups each sub group contains 5 chicks. The chicks were fed
different diets.
