A.S. Al-Ankari,M.M. Zaki,S.I. Al-Sultan
International Journal of Poultry Science , 2004,
Abstract: An attempt has been conducted to evaluate the effect of habek on performance and immunity of broiler chickens. Five levels of whole habek, 0, 25, 100, 150 and 200 g/kg were incorporated into basal diet of 125 broilers for 5 weeks. The results of the study showed that including 150 g/kg habek into broiler diet make a significant improvement in the mean body weight, daily average gain, feed intake and food conversion ratio. However, in another experiment, habek had no effect on the immune response of the birds against Newcastle disease virus live vaccine when a group of 25 birds was given basal diet supplemented with 150 g/kg habek compare to that fed basal diet only.

International Journal of Poultry Science , 2006,
Abstract: This study was designed to investigate the effect of increasing level(s) of arginine (ARG) and/or lysine (LYS) over the normal requirements of the Leghorn breeds (NRC, 1994) and their interaction on performance, ovarian activity and humoral immune response of local Saudi chickens known for their low production. The outcome of the study revealed that feed intake and specific gravity of the eggs were the only traits significantly (P< 0.05) affected by the interaction between ARG and LYS. Hen-day production did not significantly (P>0.05) increase and feed conversion improved with the higher levels of ARG and LYS (1.54 and 2.05 %, respectively) compared to the controls. In spite of the significant effect of specific gravities of the eggs, no specific trend was found in response to the treatments. Albumen height was better in the control group in both treatments which supported the higher egg size of the control group compared to the other treatments. No significant differences were found among treatments or their interaction in all ovarian and oviductal measurements. However there was a tendency for an increase in the weight of F1 follicles (largest follicles) as a result of ARG supplementation at the 2.04 % level. The study of humoral immune response of the birds revealed that mean antibodies titers (MAT) at week 24, 28, 32 and 40 of age were nearly the same in all groups of birds and no significant differences between the groups in the designated periods (P>0.05). However, at week 36 of age, MAT of group treated with 1.54% ARG and 1.05% LYS were significantly higher than the controls (P< 0.05). A significant correlation between MAT and thymus weight index at week 40 of age was observed. Based on the results of this study, it is concluded that extra ARG, LYS and their interaction did not significantly affect performance and ovarian activity of the local birds but enhanced thymus size and maintain MAT level over time.

International Journal of Poultry Science , 2004,
Abstract: A case-control study was conducted to identify risk factors associated with prevalence of swollen head syndrome (SHS) in broiler chickens in Eastern Province of Saudi Arabia (EPSA). A total of 200 birds - originated from 25 broiler flocks - confirmed cases and 200 controls were used in this study. Source of all data were the necropsy reports of the diagnostic investigations carried out at the Veterinary Teaching Hospital-King Faisal University, between July 1999 and June 2000 and the corresponding results of serological testing for turkey rhinotracheitis virus (TRTV) antibodies. Furthermore, a questionnaire was developed and used to collect data from 47 broiler farms on putative risk factors hypothesized to be associated with the prevalence of SHS in production farms. Multiple logistic regression was performed to identify factors associated with SHS. Analysis of the data revealed significant association between TRTV antibodies and clinical signs of SHS (Chi2=292.6; P<0.001) was concluded. Meanwhile, farm`s hygiene and stocking density found to be contributed in prevalence of SHS in open and closed housing system (R2= 87.99 and 53.86%, respectively).

Abdul-Rahman S. Al-Ankari
International Journal of Tropical Medicine , 2012,
Abstract: An experiment consisted of three groups of hens that were given basal diet only and/or supplemented with either high calcium or high urea was designed to assess the correlation between serum constituents and the severity of damage to the kidney`s tissues. At weeks 6, 12, 18, 24 and 30 of age, six birds from each group were sacrificed, histology of kidney tissues was examined microscopically and the abnormal changes in tissue were recorded to each bird and scored. Collected blood from 6 birds of each group at weeks 6, 12, 18, 24 and 30 of age was used to estimate serum levels of uric acid, phosphorous, magnesium, calcium, urea and creatinine. The outcome of the study revealed that severity score of kidney tissues was positively correlated with serum levels of uric acid (r = 0.992, p<0.01) and calcium (r = 0.914, p<0.01) in the group that was fed high calcium diet. It was also correlated with uric acid (r = 0.994, p<0.01) and calcium (r = 0.881, p<0.05) in group that was fed high urea diet. However, levels of serum urea, creatinine, phosphorous or manganese were not correlated (p>0.05) with severity score.

Effect of Temperature and Relative Humidity on Prevalence of Swollen Head Syndrome (SHS) in Broiler Chickens in Al-Ahsa Region-Saudi Arabia
Al-Ankari,Abdul-Rahman,El-Demerdash,Mohsen,Al- Ramadan,Mustafa
Journal of Animal and Veterinary Advances , 2012,
Abstract: Swollen head syndrome (SHS) in broiler chickens in Al-Ahsa region-Saudi Arabia had been reported between 1998 and 1999. Clinical, bacteriological and pathological investigations were carried out. Pneumovirus antibodies were detected and pathogenic E. coli strains were isolated from most of infected birds. Approximately, 37, 30 and 9% of the total cases were recorded during March, April and May, respectively. Such incidence was occurred as a result of sharp reduction in relative humidity (RH%) and increase of the temperature (T) in the climate. It could be concluded that incidence of SHS in broiler chickens reared in open system houses was enhanced by substantial changes in RH% and T.

International Journal of Poultry Science , 2009,
Abstract: IBD can only be controlled by proper vaccination. The objective of this study was to determine the efficacy of an intermediate strain of live attenuated IBD vaccine in broiler chicks at 7th day of age, as well as the effect of fish oil on immune response in birds vaccinated with IBD vaccine. One hundred forty, day-old broiler chicks were reared and used for this purpose. The chicks were divided into 7 groups A, B, C, D, E, F and G. Groups A, B and C were vaccinated via drinking water route at 7th day whereas D, E and F were vaccinated at 14th day of age. Groups B, C, E and F were fed 50gm fish oil/kg diet for one week either before or after vaccination. Group G was acted as control. Three chicks from each group were sacrificed by decapitation one week interval from the first day until 28th day of age and bursa weight to body weight (Bursal index) was recorded at these periods. Blood samples were collected for detection IBD antibody titer using ELISA at all these periods from control group for detection MDA, whereas the blood has been collected from the treated groups at a period of seven days after vaccination until the end of the experiment at 28th day of age to detect the effect of time of vaccination and fish oil supplementation on the IBD antibody titer. On necropsy, the gross pathological changes were recorded. The changes were occurred after 7 days postvaccination. The affected bursa was edematous and covered with yellowish transudate, other showed pinpoint mucosal surface necrosis, whereas other undergo atrophy. The Bursal Index (BI) was gradually increased from 1st-28th day of age in the control group, whereas in group A it was increased from the 1st to the 7th day and decreased thereafter. In group D the index was increased from the 1st-14th day and decreased thereafter until the 28th day of age. The MDA of control group was decreased from the 1st to the 28th day. The antibody titer of group A was decreased in a way similar to that of the control group, but a significant (p<0.05) difference was present between them at 14th day and thereafter, whereas in group D it was decreased from the 1st-14th day and then increased at 21st and 28th of age. Fish oil supplemented groups exhibited a slight numerical increment of both BI and antibody titer. Although single dose at the 7th day old vaccination could induce slight increase of IBD antibody in comparison to that of the control, vaccination at the 14th day of age induced high and protective level of IBD antibody titer. These may be due to the ability of vaccine at each time of vaccination to neutraliz

Ali A.S. Al-Mayah
International Journal of Poultry Science , 2006,
Abstract: The study was conducted to evaluate the effect of methionine (ME) supplementation on immune response of broiler chicks during the period of 1st -7th and 29th - 36th day of age. The amino acid powder was supplemented as 1gm/L of drinking water or as 1gm/kg of feed during these early and late period of supplementation. The mean value of bursa of Fabricius, spleen and thymus weights of chicks supplemented DL-ME during the early period of age showed significant increment (P< 0.05). Whereas chicks which were supplemented during the late period of the maturation of the immune system did not show significant increasing in lymphoid organ weights. Of all the blood parameters examined, the red blood cell counts and mean cell volume showed significant increment (P< 0.05) from the control. Other haematological values were more than that of the normal values. The values of serum and liver total protein, albumin and globulin were highest but did not vary significantly from one another and from the control. We concluded that better immune response could be obtained with adequate supplementation of ME which have been identified to be in marginal quantities in poultry feed.
The Mineralogy of Clay Fractions in the Soils of the Southern Region of Jazan, Saudi Arabia
A.S. Al-Farraj
Journal of Agronomy , 2008,
Abstract: Because of very limited information of the clay minerals of Southern Jazan region (Saudi Arabia), the mineralogy of the clay fraction has been studied. A total of nineteen soil samples from five sites representing the main landforms in the region were studied. X-ray diffraction, differential thermal and thermo gravimetric analyses were carried out on the samples. Smectite, kaolinite and illite were found to be the predominant soil minerals. Other minerals present in small quantities included: Chlorite, quartz, feldspars. DTA confirmed the low hydroxylation temperatures of kaolinite (513-540°C), which indicates disordered crystallization of kaolinite. Moreover, TGA illustrated 4-6.6% (average 5.4%) weight loss related to dehydroxylation of kaolinite. Therefore, the amount of kaolinite minerals was calculated to be 29-47% with average 39%. The clay minerals in the samples were similarity among all the sites and this could be explained by the fact that arid conditions found in the area does not support intense pedogenic processes.

Abstract: Forty five Hubbard broiler chicks and Forty five local chicks of one day old were reared on litter floor for 35 days. The chicks were divided into six groups A, B and C for broiler chicks, D, E and F for local chicks. The chicks of group A and D were vaccinated with an intermediate vaccine (Bursine -2) whereas, the chicks of group B and E were vaccinated with an intermediate-plus type of vaccine (Bursine Plus). Vaccination has been performed at 14th day. The chicks of group C and F were acted as control. Five chicks were sacrificed by decapitation from the experimental groups at 21st, 28th and 35th day and the bursae were removed, bursa weight (gram) and body weight (gram) were recorded for each individual bird. Significant decrease of bursa weight (p<0.05) was found in group B compared with that of group C at 21st day. The bursa weights in group D and E of local chicks were significantly differed at (p<0.05) from that of control group (F). The body weights of group D and E of local chicks were significantly decreased from those of group F at (p<0.05). The present study revealed that the more pathogenic intermediate vaccine (intermediate-plus) caused severe bursa of Fabricius injury in vaccinated local chicks. This could be explained by the lower degree of attenuation of this kind of vaccine and may be also related to the lack of maternally-derived antibody in these chicks.
