African swine fever (ASF) is a contagious haemorrhagic disease associated with causing heavy economic losses to the swine industry in many African countries. In 2017, Zambia experienced ASF outbreaks in Mbala District (Northern province) and for the first time in Isoka and Chinsali districts (Muchinga province). Meanwhile, another outbreak was observed in Chipata District (Eastern province). Genetic analysis of part of the B646L gene, E183L gene, CP204L gene and the central variable region of the B602L gene of ASF virus (ASFV) associated with the outbreaks in Mbala and Chipata districts was conducted. The results revealed that the ASFV detected in Mbala District was highly similar to that of the Georgia 2007/1 isolate across all the genome regions analysed. In contrast, while showing close relationship with the Georgia 2007/1 virus in the B646L gene, the ASFV detected in Chipata District showed remarkable genetic variation in the rest of the genes analysed. These results suggest that the Georgia 2007/1-like virus could be more diverse than what was previously thought, underscoring the need of continued surveillance and monitoring of ASFVs within the south-eastern African region to better understand their epidemiology and the relationships between outbreaks and their possible origin.

The current study was conducted on a total of 204 Egyptian, lactating buffalo cows. These animals were in the second or third parity, of good body condition scores and apparently healthy. The animals were raised in intensive production system on a private farm. The buffalo cows were allotted into three groups, two of these groups were experimental and the third was a control group. The first experimental group included 30 buffalo cows were undergo ovulation control by Crestar® a subcutaneous ear implant ( 3mg norgestamet ) plus Crestar® injection i.m. ( 3mg norgestamet + 5mg estradiol valerate ) at zero day. At the 7th day of implantation, PGF2α was injected i.m., then Crestar® implant was removed at the 9th day with injection of PMSG 400 iu. Timed insemination was conducted 56 hrs later. The second experimental group (24 buffalo cows) was treated by the same program, moreover they injected with GnRH at the time of insemination .The third group (150) buffalo cows was bred naturally and used as a control group. For serum progesterone assay blood samples were collected from the animals of the two experimental groups at day 0, 7 and 9 of the Crestar program. The buffalo cows of the experimental groups were closely observed for estrus signs and were rectally palpated at the time of insemination for detection of the internal estrus changes. At day 50 post insemination all animals were rectally palpated for pregnancy diagnosis. The result of the current study revealed that the visibility of estrus signs were 20 %, 16.7% and 22 % for the first, second and third group respectively. Pregnancy rate was much higher in the second group associated with the injection of GnRH at the time of insemination. Two animals of the second group were carrying twins (11 %). Serum level of progesterone was significantly higher in the 7thday in comparison with those recorded for 0 and 9th day.

This study was carried out on twelve Holstein dairy cows. Five cows were clinically healthy and considered as control; three cows with left displacement of abomasum (LDA) and four cows with right displacement of abomasum (LDA). Diagnosis of DA based on clinical examinations and confirmed by ultrasonography. The Hb, PCV%, total leucocytic count, neutrophils and abomasal fluid pH were significantly increased (P<0.05) in RDA compared to control. Serum biochemical analysis showed significant reductions of sodium, potassium, chloride and calcium in LDA and RDA and significant increases (P < 0.05) in glucose and total proteins in RDA compared to the control. Moreover, there were significant increases (P<0.001) in ALT, AST, LDH, CPK, urea and creatinine in LDA and RDA compared to control. In conclusion, abomasal displacement produces alterations in the clinical, hematological and biochemical picture compared to control healthy cow and these alterations may vary according to the type of displacement

Assessment of the sperm membrane functional status appears to be a significant marker for the fertilizing capacity of spermatozoa. The hypo osmotic swelling test (HOST) is one of the best methods to evaluate sperm membrane integrity. In the current study, we used DW and hypo osmotic solutions of 50 and 100mOsm/l of dextrose/NaCl, NaCl, sucrose and fructose. Based on the results, Among the dextrose/NaCl, NaCl, sucrose, and fructose solutions and DW, Maximum numbers of swollen of bull frozen-thawed spermatozoa were observed with DW and dextrose/NaCl solution at 50 mOsm with average response by 61.20±8.677 and 47.90±10.181 respectively. The HOST response at 3 and 60 min for all of solutions were positively correlated to each other and there was no significant difference between the responses to the HOST at 3 and 60 min after incubation in all of solutions. The significant correlation was observed between motility and dextrose/NaCl at 50 mOsm, sucrose 50 and 100 mOsm, NaCl 50 mOsm and DW. The high relationship was between motility and DW and dextrose/NaCl at 50 mosm. There was no significant correlation between DW and all of hypoosmotic solutions with staining of the spermatozoa by eosin/nigrosin. In conclusion, the water test can be efficiently used for the evaluation of the functional integrity of the plasma membrane of bull frozen-thawed spermatozoa. The hypoosmular solution of dextrose/NaCl at 50 mOsm is a good medium to evaluate bull frozen spermatozoa. The used of HOST and motility are better tests to evaluate bull frozen thawed sperm than eosin-nigrosin. The short HOST procedure (3 min) is suitable method for evaluating of membrane integrity of bull frozen/thawed spermatozoa.

The oral use of pregabalin was evaluated in this study to reveal its effects on some hematological and biochemical parameters of laboratory mice. The animals of this study were divided into three groups (twelve mice each). The control group was fed on a standard ration. The first treated group (Pregabalin 1) were dosed orally with one ml of distilled water containing Pregabalin (20 mg/ml/mice/ day). The second treated group (Pregabalin 2) were dosed orally with one ml of distilled water containing pregabalin (40mg/ml/mice/ day). The experiment continued for two successive months. The results showed that the use of pregabalin caused a significant declination in R.B.C., HGB, HCT, W.B.C., M.C.V., MCH, and MCHC of both treated groups compared them with control group and the declination was more significant in (pregabalin 2) group compared with (pregabalin 1) group. The RDWCV, RDW-SD, and PLT increased significantly in both treated groups as compared with those of the control group. However, PCT, PDW and MPV were not affected by the use of pregabalin except the MPV of (Pregabalin 2) group was significantly less than that of (Pregabalin 1) but without a significant difference compared with that of control. The Fe++, and GLU decreased significantly in both treated groups compared with the control and they declined more significantly in (Pregabalin 2) compared with (Pregabalin 1). Both the TP and Ca++ did not affected by the use of pregabalin compared with the control group (P≤0.05)

John's disease or paratuberculosis is a chronic mycobacterial infection that affectsruminants, adversely, leading to huge economic losses throughout the world. Theestimation of sero-prevalence and molecular confirmation of this disease in the cattlepopulation of south-Iraq were the objectives of this study. One of the diagnostic toolsused to detect an antibody in plasma samples was the Enzyme Linked Immuno-Sorbent Assay, indirect-ELISA was used to diagnose and estimate the sero-prevalenceof paratuberculosis in cattle. Out of 156 bovine plasma samples, 81 (51.9%) werepositive and this MAP-seroprevalence is not significantly connected to age or breedof cows (P>0.05). In this study, a PCR-based detection of IS900, distinct insertionsequences of MAP from the buffy coat of seropositive cattle (n = 81) were used as aconfirmative diagnosis. The positive PCR-based detection of IS900 was observed inanimals having high S:P% ELISA values (n=29 :35.8%).
