Effect of Probiotic Bacteria on Immunoglobulin G Concentration and Other Blood Components of Newborn Calves
M.Y. Al-Saiady
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.604.609
Abstract: Twenty-four, 3-4 days old male calves were used in this study. All animals were clinically normal. They were weighed within 24 h of arrival and divided into 3 groups A-C matched for body weight. Group A (control) calves were given a basal diet containing a combination of whole pasteurized milk and reconstituted milk replacer. In group B, a commercial culture of L. acidophilus and L. plantarum was added to the basal diet. In group C a culture of L. acidophilus 27 sc was added to the basal diet. Serum total proteins, albumin and total globulins were comparable in all three groups as were the serum concentrations of urea, BUN and triglycerides. Serum inorganic constituents also showed no significant differences between the control and treated groups. A significant increase in serum Ig G concentration was recorded in the probiotic-supplemented groups, which also showed a significant increase in body weight at 5 weeks and during the entire experimental period.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.925.931
Abstract: Twenty-four Najdi ram lambs, weighing an average of 24 kg and circa 3 months old were utilized in this trial to evaluate the effect of two feeding frequencies on growth performance, carcass characteristics, digestion coefficients, nitrogen retention and ruminal VFA and ammonia-N concentrations. The feeding protocol involved once daily feeding at 0800 h and twice daily feeding in two equal portions at 08:00 and 15:00 h lambs were offered a sufficient quantity of total daily DM (95 g DM day-1 w0.75) to resemble ad libitum consumption. All lambs were slaughtered after a 14 week feeding trial. Although, the results showed no significant effect of frequency of feeding on DMI, ADG, carcass weight, digestibility of DM, CP and ADF and N-retention, lambs fed one meal daily had higher (p<0.05) gain efficiency and NDF digestibility and lower (p<0.05) dressing percentage than lambs fed two meals daily. Rumen total VFA concentrations at all post-feeding intervals were not influenced (p>0.05) by feeding frequency, except at 10 h post-feeding; rumen VFA concentration value at 10 h post-feeding was higher (p<0.05) in lambs fed once daily than those fed twice daily. Feeding once daily resulted in a greater (p<0.05) molar proportion of propionate and a smaller (p<0.05) molar proportion of acetate than from feeding twice daily. The ruminal fluctuations in total VFA and ammonia-N concentrations were less obvious in the lambs fed twice daily than once daily.

Abstract: The purpose of this study was to investigate serological prevalence and titers of anti-Toxoplasma gondii antibodies in ewes following waves of abortion and stillbirths in a commercial flock in Riyadh, Saudi Arabia. Serum samples from 168 aborted ewes and 52 breeding rams, were tested for toxoplasmosis using an indirect enzyme-linked-immunosorbent assay (ELISA) and indirect haemagglutination test (IHA). 71 randomly sampled sheep from an abortion-free flock (60 ewes and 11 rams) were also tested, which served as controls. 149 (88.7%) ewes and 42 (80.8%) breeding rams from the flock where abortions and stillbirths occurred were positive for anti-T. gondii antibodies by ELISA. 155 ewes (92.3%) and 44 rams (84.6%), including all of the ELISA positive cases, were also positive by indirect haemagglutination test (IHA). More than 80% of the ELISA positive ewes had O.D. exceeding 100% and nearly 25% of them had O.D. of ≥150%. The IHA results, on the other hand, indicated that more than 75% of the seropositive ewes had antibody titers ≥1:1024, including 58 (37.4%) ewes with IHA titer ranging between 1:4096-1:8192 Pyrexia, depression and vaginal discharge were recorded in some ewes shortly prior to abortion. Post-mortem examination of 5 aborted fetuses revealed blood-stained fluid in the abdominal and thoracic cavities and small inflammatory and necrotic foci in the brain, liver and lungs while the placenta was reddish and friable, and its cotyledons were speckled with small whitish foci of necrosis and mineralization. T. gondii tachyzoites were demonstrated in placental sections of two ewes. By contrast, only 7 (9.9%) out of 71 randomly sampled sheep from an abortion-free flock (60 ewes and 11 rams), were positive for anti-T. gondii antibodies by ELISA and 6 (8.5%) by indirect haemagglutination (IHA) test and most of these had significantly lower titers compared to the flock where abortions and stillbirths were recorded. These results constitute the first detailed serological study of ovine toxoplasmosis in Saudi Arabia and strongly implicate toxoplasmosis as the cause of the abortions and stillbirths in these sheep.

Research Journal of Biological Sciences , 2012, DOI: 10.3923/rjbsci.2010.164.170
Abstract: This study was undertaken to determine the effect of dietary Chromium (Cr) supplementation on performance, body chemical composition, plasma glucose, Hepatosomatic Index (HSI) and liver glycogen in hybrid tilapia (Oreochromis niloticus x O. aureus). Cr-yeast or Chromic Oxide (Cr2O3) were added to fish feeds at the rates of 1 or 2 mg kg-1 while control fish received an unsupplemented diet. About 1400 fish (avg. weight 18.6 g) were randomly assigned to 5 feeding regimens, each consisting of four replicates. Each replicate was reared separately. Body Weight (BW), Feed Intake (FI), Growth Rate (GR) and Feed Efficiency Ratio (FER) were measured at days 14, 28, 42, 56, 70 and 84. Chemical composition, HSI and liver glycogen were determined at days 0, 30 and 60. Plasma glucose was measured after starving the fish for 24 h and at 1, 2, 3, 4, 6, 8 h after feeding. The results showed increased BW, FI, GR, FER, total protein, ether extract, gross energy, plasma glucose and liver glycogen and decreased ash percent in all groups. Comparison of the overall means of these variables in different feeding groups showed that BW, FI, GR and FER were significantly lower in fish receiving 2 mg kg-1 Cr-yeast while overall mean values of ether extraction and gross energy were significantly higher in fish receiving 1 mg kg-1 Cr2O3. On the other hand the highest overall mean value for liver glycogen was recorded in fish receiving 2 mg kg-1 Cr. No significant changes were observed in moisture, ash, total protein, plasma glucose or HSI. These findings indicate that the inclusion of Cr in fish feeds can lead to improvement of tilapia chemical composition and physiology, namely ether extract, total energy and liver glycogen.

Abstract: This study was undertaken to determine the effect of dietary chromium supplementation on humoral antibody response and some blood constituents in hybrid tilapia fish (Oreohromis niloticus x O. aureus). Cr-yeast or Chromic Oxide (Cr2O3) were added to fish feed at the rates of 1 or 2 mg kg-1, while control fish received unsupplemented diet. Three hundred and forty fish (Avg. weight 37.8 g) were randomly assigned to 5 feeding regimens with two replicates each. Each replicate was reared separately. The fish were immunized with Sheep Red Blood Cells (SRBCs) at 0 day and re-immunized at 30 days of the experiment to determine primary and secondary humoral antibody responses, respectively. Blood samples were collected from 15 fish/replicate at 0 and 25 days to determine blood plasma constituents and at 5 days intervals during primary and secondary immunization up to 50 days to determine anti-SRBC antibody titers. The results shown decreased plasma glucose and increased plasma cholesterol concentrations at 25 days compared to 0 days in all groups. Increased triglyceride levels was noted in fish receiving Cr2O3 (1 mg kg-1) and decreased albumin: globulin ratio in those receiving Cr yeast (2 mg kg-1) at 25 days (p<0.05). No significant changes were observed in total protein, albumin and total globulin concentrations due to either Cr treatment or feeding duration. Anti-SRBC antibody titers were significantly higher in Cr-supplemented groups versus control, with highest titers in fish receiving 2 mg kg-1 Cr-yeast supplement during secondary immunization. These findings indicate that the inclusion of Cr in the feed significantly augments humoral antibody response of tilapia.

Abstract: The present study aimed to investigate the effect of nutrition on body weight gain, ovaries development, blood components (total protein, albumen, globulin, cholesterol and glucose) and hormone level (estradiol and progesterone) in pre-pubertal she-camels. Fourteen dromedary she-camels (Camelus dromedarius) were divided in two groups (A and B) similar body weight and age at the start of the experiment (200 kg and 12 month, respectively). Group A received diet with 13% Crude Protein (CP) and 2.9 Mcal Metabolisable Energy (ME). Group B received the traditional diet of the farm. Both diets contained 25:75 forage:concentrate. Individual feed intake was calculated after 14 days of adaptation period. Feed offered and orts was recorded daily during the whole experimental period of 12 months. Blood samples were taken from each group every 15 days throughout the experimental period. Estradiol, progesterone concentrations were measured using ELISA kits. Body weight and average daily gain for the Ist 6 months did not show significant differences between treatments. On the contrary for the last 6 months, treatment A significantly increased body weight and daily weight gain when compared to B (70.07±8.17 kg and 0.389±0.05 kg day-1 vs. 37.86±8.17 kg and 0.210±0.05 kg day-1, respectively. Group A was more efficient converting feed to body weight comparing with group B. Feed Conversion Ratio (FCR) for the whole period was 11.25 and 13.74 for Group A and B, respectively. Group B had greater ovary size than Group A but the difference was not significant. Size of right ovary was smaller than the left one and season had positive effects on both right and left ovary sizes. Greater ovary sizes were observed in Winter and Spring comparing with Summer and Autumn. Group A had higher blood estradiol level comparing with Group B while there was no difference between groups in progesterone levels. It was concluded that feeding regime did not affect body weight, daily body weight gain and blood progesterone levels but improved feed conversion ratio and blood estrogen levels.

Abstract: Twenty four Najdi ram lambs, weighing an average of 42.0+0.6 kg were utilized in this experiment to evaluate the effects of various alfalfa hay particle lengths in the diets and frequency of feeding on nutrients digestibility, ruminal retention time, total mean retention time and transit time. Lambs were randomly placed in a 3x2 factorial arrangement of three dietary treatments: 9.5 and 14 mm diets where alfalfa hay was processed to 9.5 and 14 mm particle lengths, respectively mixed with 3 parts of concentrate and pelleted as total mixed ration and long hay diet where one part of loose alfalfa hay (17.8±2.4 cm) was offered in combination with 3 parts of only-concentrate pellet and two feeding frequencies: once daily feeding at 0800 h and twice daily feeding in two equal portions at 0800 and 1500 h. All dietary treatments were homogeneous in their ingredient composition. Altering the particle length of alfalfa hay in diets did not affect the digestibility of DM or CP whereas digestibilities of ADF and NDF and ruminal retention time were 4.2 and 5.3% units higher (p<0.05) and 6.3 h longer (p<0.05), respectively for the long hay diet versus the 9.5 mm pelleted diet. The total mean retention time for the long hay diet was longer (p<0.05) at 63.1 h compared with the 9.5 and 14 mm diets. Lambs fed once a day had higher (p<0.05) NDF digestibility and 4.9 and 3.8 h longer (p<0.05) ruminal and total mean retention times, respectively than lambs fed twice daily. On the other hand, neither particle length of the alfalfa hay nor frequency of feeding had affected (p>0.05) the lower tract retention time and transit time.

Journal of Animal and Veterinary Advances , 2012,
Abstract: Sixty wild birds for each of pigeons and starlings were captured in Mosul and examined clinically and serologically for avian influenza virus (AIV) infection. ELISA and haemagglutination inhibition (HI) tests were used for the detection of (AIV) antibodies in both types of examined birds. Clinically the pigeons appeared dull with loss of appetite. The percentage of positive serum antibodies titers against (AIV) was 81.8 and 50% with ELISA and HI tests, respectivly. The starlings did not show any abnormal clinical signs and all serum samples showed negative results by ELISA and HI tests. In conclusion, pigeons only showed ability to be infected with AIV subtype H9N2 and they may play an important role in spreading (AIV) as natural carriers.

World of Computer Science and Information Technology Journal , 2011,
Abstract: Trojan virus attacks pose one of the most serious threats to computer security. A Trojan horse is typically separated into two parts – a server and a client. It is the client that is cleverly disguised as significant software and positioned in peer-to-peer file sharing networks, or unauthorized download websites. The most common means of infection is through email attachments. The developer of the virus usually uses various spamming techniques in order to distribute the virus to unsuspecting users. Malware developers use chat software as another method to spread their Trojan horse viruses such as Yahoo Messenger and Skype. The objective of this paper is to explore the network packet information and detect the behavior of Trojan attacks to monitoring operating systems such as Windows and Linux. This is accomplished by detecting and analyzing the Trojan infected packet from a network segment -which passes through email attachment- before attacking a host computer.The results that have been obtained to detect information and to store infected packets through monitoring when using the web browser also compare the behaviors of Linux and Windows using the payload size after implementing the Wireshark sniffer packet results. Conclusions of the figures analysis from the packet captured data to analyze the control bits and , check the behavior of the control bits, and the usability of the operating systems Linux and Windows.

Journal of Animal and Veterinary Advances , 2012,
Abstract: Avian pox virus was isolated from skin pox lesions and oropharynex region swabs taken from peacocks (Pavo cristatus). The isolated virus produced small haemorrhagic plaques on Chorioallantoic Membrane (CAM) of developing chicken embryos. The isolated virus diagnosed by agar gel diffusion test and serum neutralization test. Morphological identification using negative staining technique of wet preparation of isolated virus is conducted and examined under the electron microscope showed oval to brick shaped particules; their sizes ranged from 300-350 150-230 nm. Chickens inoculated with the virus by scarification developed localized pox-like lesions but turkeys showed cutaneous lesions on head, legs and transient swelling of feather follicules at the site of inoculation, where as pigeon showed no lesions.
