Abstract:

This study was conducted to investigate the effect of different levels of dietary nanomicelles curcumin on serum biochemical parameters and immune system of laying hens. For this purpose, a total of 160 laying hens of Hy-Line strain were used in a completely randomized design, including 4 treatments with 4 replicates of 10 hens each. Birds were 60 weeks old and experiment period was 8 weeks. Dietary treatments were a basal diet without nano curcumin (control)  and diets containing 400, 800 and 1200 mg nanomicelles curcumin per kg. The evaluation of serum biochemical parameters was conducted in week 4 and 8. Serum immunology factors were also evaluated after SRBC injection (in week six) and blood sampling in seventh and eighth weeks of trial period which improved immune system (P<0.05). By investigating serum biochemical parameters in the middle of experiment it was revealed that ALT and AST concentration significantly decreased (P<0.05) under the effect of low-dose nano curcumin. Concentration of cholesterol, LDL and HDL: LDL ratio were affected by nanomicelle consuming levels (P<0.05) at the end of experiment. Level of 400 mg of nano curcumin showed best immune response compared to control and levels of 800 and 1200 mg. The results of this study generally showed that using different levels of nano curcumin specifically in the low level (400 mg) reduced lipids profile of serum and improved hepatic enzyme activities and immunity system in the final weeks of the experiment.

Asem M Atwa has completed his PhD in Veterinary Microbiology. He invented a patent vaccine for poultry necrotic enteritis. He worked as Laboratory Director at veterinary quarantine. Now, he is working as Researcher at Animal Medical Center.

Abstract:

Background: In Malaysia, cat ownership is very popular with most feline owners keeping on average 2-3 cats, with some exceeding 10 cats per household. As FIV and FeLV are two clinically important viral infections in cats, prevalence of these diseases would be important for both veterinarians and the public sector. 
Objective & Design: Retrospective study using domesticated cats in Malaysia to determine the seroprevalence of FIV and FeLV and risk factors associated with these infections. Between 2010 and 2016, a total of 2230 samples were collected and tested. Samples were tested at the Animal Medical Center, Malaysia for FIV antibodies and FeLV antigen using commercially available ELISA test kits.
Results: 10.03% (224/2230, 95% CI=8.80-11.26) were seropositive for FIV, 11.97% (267/2230; 95% CI=10.62-13.32) were seropositive for FeLV; and 2.6% (58/2230; 95% CI=2.01-3.17) for seropositive for both. Risk factor was adult male cats.
Conclusion: The prevalence of FIV and FeLV in Malaysia is common and as it could represent a considerable clinical concern in domesticated cats, vaccinations should be routinely given. Because of the immunosuppressive potentials of both viruses, proper control strategies from screening and routine vaccination, eradication and education programs should be also applied.

Abstract:

The aim of this study was to investigate the effect of isoflurane on total antioxidant capacity in calves. The research was carried out on 15 calves, from newborns to 3-months-old, in operations performed for a variety of reasons.  For induction, isoflurane was given at 3-5% concentration via mask during 15 minutes. Then, endotracheal intubation was performed and the maintenance was set to a concentration of 1.5-3% isoflurane in 100% oxygen two hours period. Blood samples were taken at 30 and 75 minutes, after the induction, before of anaesthesia, during two hours isoflurane anaesthesia and total antioxidant capacity were evaluated. Blood samples were centrifuged at 3500 rpm for 10 minutes at +4°C and the serum samples were obtained. The samples were maintained at -20°C until analyses. Total antioxidant capacity (TAC) was determined using commercial kits using a spectrophotometer (Eo Biotex, USA). There was no significant difference recorded on TAC during isoflurane anaesthesia. It was determined the isoflurane anesthesia had no adverse effect on total antioxidant capacity in calves.

Abstract:

Feeding high-grain diets to induce subacute ruminal acidosis (SARA) in dairy cows has consistently been associated with increase in the concentrations of lipopolysaccharide (LPS) endotoxin originating from Gram-negative bacteria in rumen fluid, and of acute phase proteins, including LPS-binding protein (LBP), in peripheral blood. Changes in the levels of acute phase proteins and LBP are indicative of a systemic immune response, possibly due to the translocation of LPS from the digestive tract. Lactoferrin (LF) is an important modulator of the immune response and inflammation. In vitro studies have shown that LF inhibits LPS-induced inflammatory response. We investigated the effect of bovine LF feeding on rumen LPS level and pH and plasma LBP in lactating dairy cows. 24 Holstein cows were randomly assigned to two groups: LF (10 g/day) feeding group (n=12) and LF (0 g/day, control) group (n=12) during 3 and 12 weeks after the parturition. Cows were fed a close-up total mixed ration (120% of TDN requirement). Postpartum, cows were fed the same close-up diet and commercial concentrate (NDF 33%, 100% of TDN requirement). Wireless ruminal pH sensors were used to obtain ruminal pH profiles (10 min interval) 3 weeks prior to calving until 9 weeks postpartum. Cows were considered to have SARA if the total below pH 5.8 was ≥180 min/day. Rumen LPS activity was lower (P<0.05) in the LF feeding group than in the control group at 12 weeks after parturition. Plasma LBP concentration was lower (P<0.05) in the LF feeding group than in the control group at 8 and 12 weeks after parturition. There were no significant differences in body weight, dry matter intake, milk yields, and rumen volatile fatty acids concentration in both groups. Cows in LF and control group had similar pH profile in lactating period, the amount of time at pH≥5.8 (67 vs. 81 min; SEM 0.45) and SARA cow was one of them in each group. Our results indicated that bovine LF feeding decreased rumen LPS activity and plasma LBP concentration in dairy cows after parturition.

Abstract:

The objective of this study was to compare the reproductive efficacy of Shortened Ovsynch (SOv) protocol in terms of service rate, conception rate and pregnancy rate with Ovsynch (OS) and Heatsynch (HS) protocols. A randomized field trial was conducted in 4 commercial dairy farms in Tehran province of Iran. Cows (n=1974) were randomly selected among those which determined non-pregnant 30 to 37 d after artificial insemination or cows which weren’t inseminated until 60 days after parturition. The animals then were randomly assigned to treatment or control groups. Cows assigned to the treatment group, followed SOv protocol (n=891) (D-0: PGF2α, Day-2: GnRH, 16-18 hours later TAI). Whereas Cows in control group were randomly assigned to OS (n=422) (D-0: GnRH, D-7: PGF2α, Day-9: GnRH, 16-18 hours later TAI) or HS (n=661) (D-0: GnRH, D-7: PGF2α, Day-9: Estradiol Benzoate, AI based on estrus detection) protocols. All cows had a CL larger than 20 mm, and a follicle between 10 and 20 mm prior initiation of the treatment. Otherwise, they would recheck 3-7 days later, until having the right size follicle and CL on their ovaries prior the initiation of the protocols. Pregnancy status of all cows was checked 30 to 37 d after AI by Ultrasonography; cows determined non-pregnant after initial enrollment, were again enrolled in the experiment, and randomly assigned to the treatment groups. Service rate (SR), conception rate (CR) and pregnancy rate (PR) was calculated for all 3 protocols. The PR of SOv-treated cows (33.67%) were higher compared to control groups (PR in OS and HS protocols were 28.67% and 27.68% respectively). The SR was significantly higher in SOv protocol, compared to HS. The CR was higher in SOv compared to both OS and HS protocols. Conclusively, the SOv protocol showed to be more reproductive and efficient compared to protocol, in terms of PR, CR and SR. It also showed higher CR and PR compared to OS protocol. The SOv protocol also could be more cost beneficial when compared to the other 2 protocols, due to shorter duration, lesser hormone injections, higher reproductive performance and being TAI based, which needs detailed economic evaluations to confirm.

Joon-Seok Chae has completed his DVM, MS, PhD from Chonbuk National University and Post-doctoral studies from Texas A&M University and University of California-Davis. He is the Professor of College of Veterinary Medicine, Seoul National University. He has published more than 170 papers in reputed journals and serving as an Editorial Board Member of repute. His recent interesting research areas are tick-borne zoonotic pathogens (Anaplasma, Ehrlichia, Rickettsia, Bartonella, Borrelia, tick-borne encephalitis and severe fever with thrombocytopenia syndrome virus, etc.).

Abstract:

Tick-borne diseases have been thought to be important in Medical and Veterinary Medicine. The genus Ornithodoros spp., which is included in Family Argasidae, is usually associated with wild animals including seabirds and it was difficult to investigate because of the location of seabirds’ nests are inaccessible. However, Ornithodoros spp. has been known for the vector of many diseases including African swine fever virus. In this study, nest, soil and litter of seabirds were collected from 10 islands in western and southern part of the Republic of Korea from July to August in 2017, known for breeding places of migratory birds, to investigate Ornithodoros species. Each time a survey was conducted, less than 10 nest, soil and litter of seabirds was collected from one island for the conservation of islands environment. Ticks were collected from nest, soil and litter of seabirds using Tullgren funnel. In total, 28 Ornithodoros spp. ticks from 70 seabird's (black-tailed gull, Larus crassirotris; and band-rumped strom petrel, Oceanodroma castro) nesting soil and litter in 4 islands (Chilsan-island, Chilbal-island, Gugul-island and Nan-island) were collected. To identify the species of Ornithodoros spp. ticks, the sequence of Ornithodoros spp. from our study showed 95% identity to Ornithodoros sawaii (KT372790) and Ornithodoros capensis (AB076080) based on 16S rRNA and 99% identity to Ornithodoros capensis (KR907243) based on 18S rRNA. Previous studies have found Ornithodoros sp. only in Chilsan Island, this study found Ornithodoros spp., in four uninhabited islands that are breeding places of migratory birds in western and southern islands of the Republic of Korea.

Abstract:

The aim of this work was to perform the comparative analysis of the thermal effect of therapeutic ultrasound (TU) on the femoral quadriceps phantom of small domestic animals. Firstly, canine femoral quadriceps model (phantom) was made, and to mimic the bone, a PVC pipe was placed inside it. Firstly, the phantom was placed in a water bath to resemble the normal temperature of the animal (37°C to 39°C), which was submitted to three different brands of TU (Sonomed IV, Sonic and Sonopulse Ibramed) with 3 MHz frequency of intensity of 1 W/cm2 for 5 minutes. In order to identify the overheating in the applied region, the thermal images were captured by an infrared camera (Flir Systems AB model), which were analyzed by Flir Tools software. After the analysis, it was verified that no overheating (above 45°C) occurred in any applications. With Sonopulse Ibramed apparatus, the maximum temperature with the closed state phantom was 44.1°C and opened state was 42.27°C. With the sonic, the maximum temperature reached was 44.3°C with closed phantom, it was the highest temperature between brands, and with the phantom opened the temperature reach 40.3°C.inally, the sonomed IV apparatus the maximum closed temperature was 40.73°C and 39.8°C opened. It was proved that there is no risk to apply therapeutic ultrasound with this intensity, but the phantom should be improved to reach the acoustic and thermal properties of the body.

Abstract:

Beef is still the most widely consumed protein source in the world, but knowing how to distinguish different types of cuts is an uncommon factor for people in general. Based on it, trying to ensure that the customer is aware of the type of meat cut he is buying, this project proposes the development a technique by ultrasound to analyze the longitudinal velocity of 3 types of meat cuts from females of the Nellore breed, approximately 2 years of age. These cuts with average thickness of 0.87±0.05cm of distinct regions (strip loin, full rump and rump tail), were submerged in water and using transducers at 1.0 MHz (Olimpicus) whose emit ultrasonic pulses through the refringent medium and the sample, reaching the reflector located below it, returning later to the transducer. The signals were collected 5 times through a software developed in Labview platform. The results showed that strip loin velocity was 1594.32±15.37, full rump 1589.17±13.64 and rump tail 1591.53±8.15 m/s. The anova analysis at 0.05 shows p value of 0.818 and F of 0.20. There was no difference between the meat cuts longitudinal velocity, but the result obtained, despite the margin of insecurity, was satisfactory since the coefficient of variation in the 3 samples was 1%.

Biography:

Paulo Alex Machado Carneiro obtained a DVM degree by the Amazon Federal Rural University (1992), Master of Science degree at the University of Sao Paulo (2000), and currently is a PhD candidate in the Comparative Medicine and Integrative Biology Program at Michigan State University. He has 25 years of experience teaching and 11 years of governance as President of the Amazonas State Board of Veterinary Medicine. He is Amazonas State representative at several regional and national meetings related to the public health, animal production, and disease surveillance. He also has experience and expertise in beef, dairy, and veterinary regulatory affairs in Brazil and the USA.

Abstract:

Brazilian national mortality and incidence rates were reduced by 38.9% (3.6 to 2.2/ 100,000) and 34.1% (51.8 to 33.2/100,000), respectively, from 1990 to 2015. In contrast to the national figures, in the Amazonas State the TB incidence rate have been rising in the last decade, reaching 67.2/100,000 persons in 2016 - the highest incidence in the country, third highest mortality rate due to TB (3.2/100.00). Despite the efforts of the local Amazonas authorities in diagnosing TB, and free access to treatment of TB, a significant reduction in TB cases has not been achieved. Alarmingly, the major risk factors associated with zoonotic TB (due to M. bovis), such as the occurrence of M. bovis, low rates of milk pasteurization, and high consumption of products from raw milk are routine in Amazonas’s municipalities, and physicians might be unaware of the risk of the occurrence of zoonotic infection, and therefore specific diagnosis is not requested. This project aims to uncover the contribution of M. bovis to human tuberculosis in Amazonas State. The specific aims of this study are to: 1) determine the prevalence of M. bovis in M. tuberculosis complex in animals in slaughterhouses (cattle and buffalo), human population, milk, and cheese from raw milk; and 2) determine the risk factors associated with the prevalence in humans. To date the preliminary results show that the disease is widespread and that the prevalence is much higher than predicted (81.4% vs 13%), indicating that the bovine tuberculosis is a significant problem in Amazonas State.

Abstract:

In order to strengthen the reliability in the sale and purchase of meat, it is necessary to certify the type of cuts bought by the customer. Therefore, the ultrasound was used to verify if the attenuation coefficient is an intrinsic acoustic property to each meat cuts, generating positive impacts in the modernization of the meat trade. Thus, the pulse-echo technique was employed using a function generator applying an electric pulse at 1.0 MHz in one transducer (Olimpicus) immersed in distilled water aligned with an aluminum reflector by positioners. An oscilloscope (TEKTRONIX TPS2024) connected to a computer via the USB port was used to save and process the signal. Three samples of each meat cuts (strip loin, full rump and rump tail) with average thickness of 0.87±0.05 cm were immerse in water at 26oC where the ultrasound signals were transmitted and receipt by transducer five times in order to determine the acoustic attenuation. The signals were acquired and processed by a software developed in Labview Platform. The results showed that strip loin attenuation was 3.15±1.08, full rump 1.35±1.07 and rump tail 2.37±1.20 dB/cm2. The anova analysis at α 0.05 shows p-value of 0.072 and F of 3.28. There was no difference between the meat cuts attenuation, but maybe this is due to technical difficulties. Some technical improvements can be made.

Abstract:

Calf disease is an important problem on many farms that can have serious effects on calf survival and productivity. Calf diarrhea is the most common causes of morbidity and mortality in cattle in Korea. The objective of this study was to investigate calf diarrhea management on Korean native cattle farm. Data were collected prospectively on parameters related to calf diarrhea on 10 farms located in Jeonbuk/Jeonnam provinces in Korea. A 30-question survey about health status, hygiene, farm environment and management practices was administered to farmer by face-to-face interview. Of these farms, one farm with no presence of calf diarrhea was chosen to serve as a standard (control). Another 9 farms with presence of calf diarrhea were divided into 2 groups based on the incidence of calf diarrhea (less than 50%, 50% or more). Several calf management conditions showed no difference on the visited farms. These factors include colostrum management and calf treatment by owner. In contrast, other factors such as hygiene management (frequency of cleaning the farm/calving area, placement of individual calf space, vaccination for diarrhea, etc.) differed between farms and showed an association with the incidence of calf diarrhea. This study identifies several factors associated with calf diarrhea that should be further investigated to establish calf management protocol to reduce the calf diarrhea in Korea.
