This study was conducted to evaluatethe degree of biosecurity level with especial reference to Salmonella Spp as an example to explain the expected causes and risk factors that leads to spread them in poultry flocks in Egypt then studied farms evaluated for the sensitivity of Salmonella isolates to the most common disinfectants used in Egypt. About 300 samples (100 cloacal swabs, 100 liver and intestinal samples, 100 litter samples) were collected from 10 broiler farms with different age (at 0 old day, one week, 2,4 and 6 weeks of age) then the samples were investigated for Salmonella Sppand subsequently identified based on biochemical and serological tests.The obtained results showed that 35 Salmonella species were isolated from 10 broiler poultry houses (25%);(6%) and (4%) from cloacal swab;liver and litter, respectively. Average prevalence of Salmonella spp. was 11.33 % in open broiler houses whether raised Cobb, Ross or Sasso breeds. Salmonella Typhimurium, S. enteritidis and S.Kentucky were the most serovars out of the 35 detected isolates. There was great statistical significant difference in the sensitivity of Salmonella isolates to the most common disinfectants(P<0.05)asVerkon- S® achieved 3 log reduction, after 5-minute,Formalin and Phenique were achieved 3 log reductions against S. entriditisafter one-minute Aldekol Des- Gda® achieved one log reduction after one minute, TH4®,Biosentry® 904 and Iodophoreachieved 2 log reductions after 5 minutes.

Salmonellosis is a major problem for the poultry industry, and this problem represents a critical food safety hazard. Resistance to antimicrobial agents within nontyphoidal Salmonellae is a serious problem. The present study aimed to analyze genetically some β-lactamase resistance genes and some virulence associated genes in Salmonella isolates from broiler chicken. Five hundred samples were collected from diseased broiler chickens of different ages (3-6 weeks) from different farms in Assiut Governorate in Egypt during the period from January 2015 to December 2015. Bacteriological examination showed that 26 Salmonella isolates were recovered with a prevalence rate of 5.2% Serotyping of Salmonella isolates showed that S. Enteritidis S. Typhimurium, and S. Kentuky were identified at rates of 50%, 30.8% and 19.2%, respectively. Results of antibiogram showed that 18 Salmonella isolates (92.3%) were multidrug resistant. All isolates were screened for the presence of 2 β-lactamase resistance genes (blaCTX and blaCMY) as well as 3 virulence genes (stn, invA and hilA) using multiplex PCR. The overall prevalences were 53.9% for blaCTX and 34.6% for blaCMY. Meanwhile, stn, invA and hilA genes were found in 96.2%, 100% and 84.7% of isolates, respectively.

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.

Premaalatha B. | Jamnah, O. | Tang, W. W. | Chandrawathani P.
The local river terrapins (Batagur affinis) are an important aspect of the river ecosystem. The Turtle Conservation Centre in Bota Kanan noted morbidity and mortality in its terrapin population and some were sent for full laboratory investigationto diagnose cause of death. The faecal samples were subjected to faecal floatation technique whereby ascarid eggs were observed indicating that the turtles had helminth infection. Ascarid eggs had thick walls and measured at 140.6 μm to 149.7 μm in diameter. Apart from this, post-mortem examination of intestinal contents also showed presence of nematodes identified as Oesophagostomum sp. Treatment and control have to be instituted to prevent further morbidity and losses.

In the Malaysian environment horses are primarily used in sports activities such as racing, endurance, dressage and show jumping as well as in recreational pursuits and police work. Recently, the Perak Turf Club witnessed the death of a four-yearold thoroughbred mare which was given enrofloxacin injection as treatment and was regularly dewormed and vaccinated againstequine influenza, Japanese encephalitis and tetanus. Post-mortem examination of intestinal contents revealed presence of worms. The sample was then sent to the Veterinary Research Institute (VRI), Perak for morphological identification of the worm. The worm was identified as Parascaris equorum. Thus, awareness ongastrointestinal parasites should be raised especially by recommending improved management practices such as proper manure disposal and deworming procedures to control parasite infestations as well as good management and nutrition.

The present study describes the use of electrochemiluminescenceimmunoassay (ECL) with the specific human kit for measuring plasma testosterone and progesterone in ovine. This study wascarried out on 16 mixed age animals of the local breed. They were divided into two groups of both sexes, namely Male-1 Group,Male-2 Group, Female-1 Group and Female-2 Group. Blood samples were collected from the jugular vein into tubes containing EDTAand centrifuged at 1500 rpm for 20 min. Plasma was rapidly separated and stored at -20° C until assayed. The reproducibilityinter- and intra-assay of the P4- and T-ECL is satisfactory (2.11-7.3 %). The accuracy (93-102 %) and the test of parallelism were largely acceptable. No cross-reaction was observed with the different hormones including PMSG,hCG, progesterone,testosterone, oxytocin and PGF2α when concentrations of 10 UI/ml and 10-3 UI/ml were used. T concentrations were higher in Male-1 Group than in Male2 Group (1.67 ± 1.15 and 0.38 ± 0.45 ng/ml, respectively). The female-1 Group showed very high P4 concentrations (15.17 ± 4.91 ng/ ml) compared to the Female-2 Group (0.08 ± 0.04 ng/ml). The results obtained clearly show that human ECL system can be used to measure progesterone and testosterone in plasma ovine

A preliminary study on the effect of probiotics in fermented palm kernel meal (FPKM) and total mixed ration (TMR) to improve milk production in dairy cattle was carried out. TMR feeding enhances feed intake, improves the ecology of the rumen leading to stimulated microbial activity to digest more feed, and then finally increases productivity of the cows. Probiotics ofBacillus spp. was given through concentrate after a fermentation process for three days. The trial was carried out at the Dairy Unit, Veterinary Institute, Kluang, Johore. Twenty Mafriwal cows with low milk production were selected and divided into twoequivalent groups. Each group consisted of 10 cows. Group A were fed with TMR. Group B received TMR and 100 grams perhead/day FPKM (FPKM, probiotics Bacillus spp. and mollases). The cows were given TMR daily which consisted of 20 kg per headof fresh Napier grass, 5 kg per head palm kernel meal, 1 kg per head soya bean meal, 1 kg per head corn, 0.5 kg per head molassesand 0.5 kg per head of enalac. Feeding trial period was carried out for four weeks. Feed was given twice a day, morning and lateafternoon, meanwhile water was given adlibitum. Animals were given the same diet for seven days for an adaptation period.Milk was sampled twice a day for four weeks and were recorded accordingly. The average of daily and weekly milk productionwere calculated. The animals from Group B showed an improvement of milk production before trial to the fourth week from 5.2litres/head/day to 6.99 litres/head/day i.e. 14.80% to 34.44% as compared to Group A.

Agbajelola, V. I. | Lawal, I. R. | Falohun, O. O.
Zoonotic parasitic gastroenteritis has been well-known as a serious limitation to humans as well as livestock productivityin terms of man-power, pathology and fiscal losses, as human infection with these helminths from cattle can resultfrom consumption of meat containing the infective stage of the worm. This study therefore investigates the presence ofzoonotic helminth infections among cattle in Minna metropolis, and scientific basis for their potential transmission to humanpopulation. A total of 184 diarrhoeic faecal samples from cattle were collected from September 2014 to June 2015 in Minna,Niger state and processed using the direct faecal microscopic examination techniques. The obtained results showed that a total of 81 (44%) samples were positive including Ascaris sp, Fasciola gigantica, Trichuris sp. and Taenia sp. with infection rates of 22.3%, 12%, 2.2% and 0.5% respectively, and mixed infections of Fasciola gigantic with Ascaris sp. (4.3%) , and Ascaris sp. with Trichuris sp. (2.7%). Poor human hygiene, inadequate livestock husbandry managements and restriction of animals to residential areas are the major factors responsible for the high prevalence of zoonotic helminths and geo-helminths in the study area. Therefore veterinarians, animal handlers and livestock owners should practice personal hygienic and safe management practices for animal rearing and treatments.
