S. M. S. El-Ayouby | O. R. Salib | H. K. El-Deen
This study was conducted to evaluate the protective effect of Brucella melitensis Rev.1 and the use of BCG vaccine as immunostimulant by subcutaneous injection in Guinea pigs. Lab. animals were divided into 8 groups: Combined Rev.1 and BCG vaccines injected in the1st group & both vaccines were injected simultaneously in the 2nd group. Three groups sensitized with BCG vaccine then injected with Rev.1 vaccine one week, two week & three weeks intervals respectively. Other two groups were injected with BCG and Rev.1 vaccine individually. The last one was unvaccinated control. All injected animals showed resistance to infection with 16 M strain (90 %, 80 %, 80, 60 %, 70 %, 0 % and 70 % respectively).Thus animals vaccinated with bivalent Rev.1 and BCG vaccines (in one shot) showed the best protective level to infection

The efficacy of four infectious bursal disease virus (IBDV) vaccines including intermediate (D78) and intermediate plus (228E, IBD-Blen and Bursa-Vac+) were compared in priming vaccination of 10 days commercial old male layer chicks. There were different parameters were measured for testing these vaccines including; the immunogenic efficacy, the effect on performance, organ (bursa, spleen, and proventriculus) body weight index as well as histopathological examination of bursa, spleen, proventriculus and thymus. Chick was received a dose of 102 EID50 from one IBDV vaccine out of 228E, IBD-Blen or Bursa-Vac+, while D78 dose was 104 EID50. The results cleared out that all the tested vaccines passed through the maternal derived antibodies 2480.133 + 156.3. All vaccines stimulate antibody formation as measured by ELISA test. The used vaccines not affect markedly body weight and feed intake, as there were no significant differences between the control group and the vaccinated ones in the mean body weight and the feed conversion rate. Furthermore, the bursa: body weight index of vaccinated groups were generally less than those of control one at all intervals, while the spleen and proventriculus: spleen: body weight index of vaccinated groups was higher than control on at the end of the observation period. The used vaccines induced histopathological changes in bursa, spleen , proventriculus and thymus glands. These results indicated that all tested vaccine are of value in vaccination of commercial chicks from vaccinated breeders

Stability study of biological products especially living bacterial vaccines plays an important role for determination of product changes in maintenance period and ensures safety, efficacy and maintenance of biological properties of the vaccines. So, the objective of this study was to establish stability and keeping quality of the local Brucella melitensis Rev-1 vaccine using different types of stabilizers in lyophilization process. A long-term stability study was carried out for four batches of reduced-dose Brucella melitensis Rev-1 vaccine manufactured by veterinary serum and vaccine research institute using four different stabilizers. These stabilizers were (A) sucrose and skimmed milk, (B and C) different concentrations of sucrose, sodium glutamate and gelatin, and (D) casein, sucrose and sodium glutamate. The quality control tests including colony forming unit, purity, dissociation and physicochemical tests on all batches until 12 months post- production were performed. The obtained results indicated that, in spite of collapse (shrinkage) of lyophilized cake in a number of bottles in batches prepared using stabilizer A, the brucella vaccine batches were stable and met the specification recommended by OIE 2012 for 12 months post-production in vaccine batches with stabilizers A and D.

The objective of this work was to estimate the lead (Pb), Cadmium (Cd), Copper (Cu), Zinc (Zn), Iron (Fe) and Manganese (Mn) levels in drinking water, layer feed and muscle samples were collected during winter season from two layer farms which present at two different areas, non industrial area (Integrated poultry project in El-Azab) and industrial area (Kom Oshim) in Tamia district in El-Fayoum province, Egypt. All samples will be analyzed to determine the translocations of heavy metals from water and feed to the bird's muscle. The results explained that the mean metal concentrations in the different samples of selected poultry farms are Pb (1.1034±0.097, 1.173±0.129), (2.891±0.194, 3.182±0.28) and (0.071±0.03, 0.099±0.0396 ppm). Cd (0.419±0.004, 0.389±0.017), (0.508±0.017, 0.5854±0.003) and (0.005±0.0013, 0.0125±0.003 ppm). Cu (5.9±2.1, 0.8596±0.054), (9.15±1.202, 14.75±0.417) and (0.0442±0.0075, 0.03032±0.004 ppm). Zn (14.50±1.285, 13.628±1.053), (57.605±3.06, 58.319±0.73) and (0.0668±0.018, 0.016±0.00498 ppm). Fe (171.011±79.6, 186.74±72.65), (153.58±15.3, 124.12±3.26) and (0.013±0.008 ppm, ND). And Mn (3.187±1.539, 1.398±0.768), (84.98±5.676, 85.884±1.07) and (0.0056±0.0037ppm, ND) for muscle, layer feeds and drinking water which were collected from non industrial area and industrial area in ElFayoum province, Egypt, respectively. These data indicated that Pb and Cd in muscle, layer feeds and drinking water collected from industrial area were higher than that collected from non industrial area. Also these metals residual concentrations particularly in layer muscle and drinking water were more than the permissible limits.

Abdullah, R. | Chai, I. I. | Hamzah, H. | F. , Jesse F. A. | Ho, H. W. | Hassim, H. A. | Azlan C. A. | Wahid, H.
The objective of the study was to establish the baseline values for blood and coagulation parameters in normal and healthy rusa deer (Rusa timorensis) of different ages and sexes. The samplepopulation consists of 40 rusa deer, divided into four groups of (i) juvenile males (ii) juvenile females (iii) adult males and (iv) adult females. The findings showed significant (p<0.05) higher values in erythrocyte count, calcium concentration and prothrombin time in the adult males compared to adult female rusa deer. On the other hand, the total protein concentration was significantly higher in adult females than adult male deer. No significant differences in blood or coagulation parameters were observed between sexes in the juvenile deer. Between age group, the adult deer had significantly higher mean cell volume, plasma protein and globulin concentration than juvenile rusa deer. Thus, it is necessary to take into account the age and sex of the rusa deer when using blood reference values for the diagnosis of diseases or health assessment.

Multiple ovulation and embryo transfer is one of the reproductivetechnologies which is important to increase animal production. In this case report, four cows were selected as donors while elevencows were selected as recipients. Both donors and recipients had undergone the same procedures and steps for multiple ovulation and embryo transfer (MOET), such as cow preparation, synchronisation and where only donor cows follow the superovulation protocol. Cows were artificially inseminated and the embryos were flushed and graded. Out of four selected cows for donor, one of them was pregnant and only two cows actuallyproduced the embryos. The recovery rate for the embryo collection was 70.1%, and from 13 embryos (including unfertilised ova), 84.6% of the embryos was classified as good quality and suitable for embryo transfer. The overall results showed that out of eight recipients, five cows were detected pregnant, a 62.5% pregnancy rate. The aim of this report is to describe the procedures aswell as the factors that affect the successful of the MOET programme.

Roslan M. Y. | Suhaimi D. | Norazean M. F. | Nurul Aini M. Y. | Nurshuhada S.
Biogas plant is an anaerobic digester that produces biogas fromorganic materials. The general purpose of implementing biogas plant in an animal farm is to obtain biogas from animal manure and the effluent of biogas digester after fermentation process can be used as organic fertiliser. There are 15 biogas plants based on livestock waste that have been developed throughout Malaysia until 2018. Two more biogas plants are planned to be built in Segamat and Keningau. All biogas plants built were originally aimed for domestic use which is as source of energyused for cooking and incinerator as well as to generate electricity for farm use. Out of 15 biogas plants, 7 plants were built on cattle farms, 4 plants on pig farms, 3 plantson poultry farms and only 1 plant on buffalo farm. Total construction cost for each biogas plant is between MYR4,500 to MYR30 million. Based on the survey conducted, it revealed that only 40% of the plants are still functional. However, 60% were dormant or nonfunctional due to poor maintenance, design errors, lack of technical knowledge to run the system consistently, improper planning and monitoring or insufficient livestock waste to continuously producing biogas.

Salmonella stained antigen has been widely used in Malaysia for detection of Salmonella infection in poultry. Growth phase of four Salmonella enterica serovar Pullorum (SP 9-25, SP 14/11, SP 690/79 and SP 7107/07) used in the antigen production were investigated based on colony enumeration and turbidity. This study aimed to determine the growth curve and the difference between S. Pullorum isolates based on turbidity measurement and spread plate technique for optimisation towards biomass production of salmonella antigen using bioreactor. Current production of the antigen used conventional methods and the number of bacterial cells is low and with several other drawbacks. The isolates were cultured in nutrient broth, incubated aerobically with constant shake for 48 hours to determine the lag, exponential, stationary and the death phase of the bacteria. Turbidity of the bacterial cells was measured using spectrophotometer and the colony was counted using total plate count every four hours. Based on the colony forming unit per milliliter, SP 690/79 strain showed the fastest growth where this bacteria achieved its mid-exponential growth at 8 hours. This is followed by SP 14/11 where this strain demonstrated the mid-exponential growth at 12 hours. The other two strains (SP 9-25 and SP 7107-07) are the slowest growth where their mid-exponential growth was measured at 14 hours. However, SP 690/79also the fastest strain entering the death phase which demonstrates the difference growth of the S. Pullorum strains. This study demonstrates that each S. Pullorum strains multiplying and dying at different phase though in the same serovar.
