Objective: The aim of this research is to study the effectiveness of mosquito magnet (MM) for reducing mosquitoes (Diptera) populations in coastal areas.Materials and methods: The study sites are in the coastal area of Samut Songkhram province, Thailand, which is divided into two locations; one that is 2 km and another that is 4 km in distance from the sea. We used the Mosquito Magnet® Independence (MMI) trap for effective field testing in Samut Songkhram Province, Thailand. Traps were placed 100 m away from the house (one trap per location) and mosquitoes were collected at night from 6 PM to 6 AM during September and October 2017 (30 days).Results: A total of 2,561 adult mosquitoes, including Anopheles epiroticus Linton & Harbach, Culex quinquefasciatus Say, Cx. sitiens Wiedmann, and Cx. gelidus Theobald were collected by MMI. At a 2-km distance from the sea were captured more mosquitoes per night more than at a 4-km distance (63.63 ± 42.30 vs. 21.70 ± 12.42). The comparison of effectiveness of MMI in two locations of the coastal area was shown to have a statistically significant difference (p < 0.05) and analysis of the correlation between the number of mosquitoes caught in coastal areas, including at a 2- and 4-km distance from the sea, accounting for weather factors, we found that the effectiveness ofMMI was not correlated with weather (p > 0.05). Conclusion: Overall, this study demonstrated that MM can be used to control mosquitoes in coastal areas with high efficiency, especially 2 km away from the sea.

Objective: The objectives of our study were to estimate the effect of some non-genetic factors on production and reproduction traits of Egyptian buffaloes and to estimate the breeding values for these traits.Materials and Methods: Data from 965 lactation records of 305 Egyptian buffalo cows mated by 73 sires that were raised at Mahallet Mousa Experimental farms of Animal Production Research Institute were collected. Dairy records covered the period from 2001 to 2015. The data were arranged and statistically analyzed using SAS version 9.1.3 to study the effect of non-genetic factors and the MTDFREMAL program was included in estimating the expected breeding values.Results: Our results showed that buffalo cows that calved in winter season recorded the highest and significant total milk yield (TMY) and daily milk yield (DMY) traits and the best reproductive performance was indicated by the lower number of services per conception and the shortest calving interval (CI) period. Moreover, age at first calving and dry period (DP) showed a highly significant effect on the TMY and DMY. A significant effect for the level of milk production on days open (DO) period was recorded in our study. The range of sires EBV was 540 kg, 295.2 days, 113.9 days, 2.8 months, and 71.1 days for TMY, LL, DO, CI, and DP, respectively.Conclusion: Buffalos breeders must consider the season of calving, parity, and DP in management program because they greatly affect the farm productivity and profitability and they must select animals with higher breeding values to be the parent of the next generation.

Chinedu Adive Akwuobu | Joseph Odeh Agbo | Raphael Agbo-Peters Ofukwu
Objective: The present study was initiated to ascertain the level of shedding of salmonellae by dogs in Makurdi area and to highlight the risk of infection for dog-owners.Materials and Methods: Rectal swabs from 200 dogs from different locations in the studyarea were examined in the study. The samples were cultured for salmonellae using Rappaport-Vassiliadis enrichment broth (Oxoid) and brilliant green agar (Oxoid). Suspected Salmonella isolates were serologically identified.Results: Overall, Salmonellae organisms were isolated from 11 (5.5%) of the 200 dogs sampled. Prevalence rates of 5.6% and 4.5% were recorded for apparently healthy and clinically sick dogs, respectively. Salmonella was respectively isolated from 4.1% to 9.1% of male and female dogs. Dogs aged 4 years and above recorded the highest prevalence rate. The study revealed a low prevalence rate in Nigerian local breed (mongrels) and high prevalence rates in exotic breeds of dogs.Conclusion: The isolation of salmonellae in apparently healthy and clinically sick dogs in this study indicates a carrier status which may constitute a serious problem in disease control in the study area. The lower prevalence rate of Salmonella infection in mongrels could be an indication of resistance to Salmonella in local breeds of dogs and should generate interest in research in the pathogenicity and pathogenesis of salmonellae in mongrels.

Objective: This current study was subjected to investigate the influence of two-stage fermentation by Chrysonilia crassa and Bacillus subtilis on nutritional values and antioxidative properties of agro-industrial by-products.Materials and methods: Two-stage fermentation with Ch. crassa (inoculated in advance; single-step fermentation) and B. subtilis (inoculated later; two-step fermentation) was conducted on agro-industrial by-products, i.e., banana peel meals, cassava pulp, and rice bran. The pH measurement, microbial enumeration, proximate, and antioxidant analyses were conducted following 4- and 2-days aerobic incubation with Ch. crassa and B. subtilis, respectively.Results: The pH of banana peels and cassava pulp increased with Ch. crassa-fermentation, but then decreased following B. subtilis-fermentation. Chrysonilia crassa-fermentation did not change, but B. subtilis-fermentation decreased pH of rice bran. The number of lactic acid bacteria was higher in two-stage than in single-stage fermented by-products. Crude protein and fat were higher in fermented than in unfermented banana peels. Crude protein was higher in single- and two-stage fermented, while fat higher in single-stage fermented than in unfermented cassava pulp. Crude fat and ash contents increased with fermentation in rice bran. Single-stage fermentation increased some of amino acids contents in banana peels and cassava pulp. The concentration of polyphenols, tannins, and antioxidant potential of banana peels reduced with fermentation. Total polyphenols and tannins were higher, whereas antioxidant activity was lower in fermented than in unfermented cassava pulp. Total polyphenols, tannins, and antioxidant activity were lower in two-stage than in single-stage fermented and unfermented rice bran.Conclusion: Single-stage fermentation with Ch. crassa improved nutritional characteristics of agro-industrial by-products.

Objective: Sarcocystis spp. are common parasites and in terms of economics and pathogenicity in domestic animals is important. The purpose of this work was to define the rate of contamination of slaughtered carcasses of cattle to Sarcocystis using digestive and histopathological methods in southeast Iran.Material and Methods: In this descriptive laboratory study for 1 year, 500 carcasses were examined and isolated bradyzoites of Sarcocystis with the digest method. Also, tissue samples from the esophagus and diaphragm were considered for pathologic studies and stained with hematoxylin and eosin of sections of histopathological.Results: The results showed that the highest contaminations were in imported male animals aged 23 years old in the spring. There was a significant difference (p < 0.05) in the prevalence rate with the sex and race of cattle but no significant difference (p > 0.05) in the prevalence rate with age and season.Conclusion: Infection with Sarcocystis is common in oxen in this region. The imported cattle are more infected. It seems that racing and the environmental condition affect the prevalence of Sarcocystosis. [J Adv Vet Anim Res 2018; 5(4.000): 381-387]

Objective: The aim of this paper is to report surgical correction of ureteric rupture due to stenosis induced secondary to accidental injury by placing nephrovesical subcutaneous ureteric bypass in a dog and postoperative long term outcomes. Materials and methods: Imaging techniques revealed multiple bone fractures as well as left proximal ureter injury. The all bone fractures were corrected using standard techniques while left proximal ureter injury was treated as conservation medical therapy. One month later, contrast media were also found in proximal ureter and abdomen which indicated ureter rupture. This rupture was corrected surgically by nephrovesical subcutaneous ureteric bypass (SUB) under fluoroscopy guidance.Results: First day after accidental injury, the serum BUN and CRE were 10.7 mg/dL and 0.9 mg/dL, respectively which indicated kidney injury but by conservative therapy these parameters were lowered gradually. On the 5th day after considering these parameters, the dog was judged normal. However, on the 31st day BUN and CRE were 14.3 mg/dL and 0.8 mg/Kg, respectively. The Doppler ultrasonography revealed hydroneprosis, proximal ureter stenosis and high resistive index (0.72±0.02) in the renal arcuate artery indicating renal abnormalities due to ureter obstruction. On re-examination by radiography after one month postoperatively, revealed that patency of the device and normal renal function. The dog was clinically normal with normal urination and no complications were found 6 months postoperatively.Conclusion: In view of the above findings, it is suggested that the SUB system can be a better alternative to preserve the kidney in non-reparable traumatic ureteral damage in dogs.
