Effects of maintenance of propofol-ketamine anesthesia with repeat bolus and constant rate infusion of propofol on physiological, biochemical, anesthetic and analgesic indices in dogs Полный текст
2015
Njoku, Njoku Uchechukwu
The research work was aimed at investigating physiological, biochemical, analgesic and anesthetic indices of dogs anesthetized with propofol-ketamine and maintained with repeat bolus and constant infusions of propofol. Eight dogs, assigned to two groups (n=4), were used in this study. All dogs were pre-medicated with atropine (at 0.03 mg/kg bwt) and xylazine (at 2 mg/kg bwt). Anesthesia was induced by a concurrent administration of propofol (at 4 mg/kg bwt) and ketamine (at 2.5 mg/kg bwt). Maintenance of anesthesia in Group 1 was done with a repeat bolus of propofol (at 2 mg/kg bwt), while in Group 2 it was done with a constant infusion of propofol (at 0.2 mg/kg bwt/min). Gastrotomy was performed in both groups, and anesthesia was maintained for 60 min. Physiological, analgesic, anesthetic parameters and plasma glucose concentration were measured. There was no significant (P>0.05) difference found in the analgesia and pedal reflex scores, durations of analgesia and recumbency, recovery time and standing time between the groups. The heart rate, respiratory rate and rectal temperature reduced significantly (P<0.05) from the baseline values. The heart and respiratory rates were significantly (P<0.05) lowered in Group 1 than in Group 2. Blood glucose was significantly (P<0.05) elevated at recovery from anesthesia in both groups. However, the value did not differ significantly (P>0.05) between the groups. In conclusion, both maintenance protocols are suitable for dogs, although the repeat bolus technique produces marked cardiopulmonary depression.http://dx.doi.org/10.5455/javar.2015.b114

The study was conducted to know the effects of several genetic and non-genetic factors like season, sex, year of birth, genotype of calves and milk yield of dam associated with growth performance of crossbred calves. Data were collected from registered farmers during the period of May, 2011 to April, 2013. Birth weight, three-month weight, six-month weight, weaning weight and heritability estimates of those growth performances were performed using a total of 82 registered calves which had pedigree information having the genotypes of 25% Local - 75% Friesian and 37.5% Local - 62.5% Friesian. The average birth, three-month, six-month and weaning weight of calves were 29.33, 64.32, 99.06 and 151.77 kg, respectively. The effects of non-genetic factors like sex, season of birth and genotype were non-significant (P>0.05) for the traits birth weight, three-month, six-month, weaning weight and average daily gain of calves. However, year of birth was found significant on birth (P<0.01), three-month and six-month (P<0.05) weight; but non-significant (P>0.05) on weaning weight and average daily gain of calves. The heritability estimates were 0.40±0.09, 0.46±0.08, 0.39±0.12 and 0.50±0.12 for the traits birth weight, three-month weight, six-month weight and weaning weight, respectively. Estimated heritabilities of live weights suggest that individual own performance basis selection would be more effective for increasing growth and therefore, should be paid more emphasis in cattle improvement program. http://dx.doi.org/10.5455/javar.2015.b116

In this study, an attempt was undertaken to know the prevalence and antibiogram profile of Mycobacterium spp. in poultry and its immediate environments. A total of 130 samples comprising of droppings (n=80), egg washing (n=18), drinking water (n=14), hand washing from farm workers (n=6) and litter (n=12) were collected from six poultry farms located in and around Bangladesh Agricultural University (BAU). Samples were inoculated onto 7H10 Middlebrook agar and incubated aerobically at 37ºC for 7-14 days. Identification of Mycobacterium spp. was performed by colonial morphology, acid fast staining, and biochemical tests. Molecular identification of Mycobacterium spp. at genus level was performed by polymerase chain reaction (PCR) assay targeting 65-kDa heat shock protein gene. Antibiogram profile of Mycobacterium spp. was performed against five antibiotics namely Rifampin, Azithromycin, Ciprofloxacin, Streptomycin and Doxycycline by disc diffusion method. Three Mycobacterium spp. were isolated from dropping samples of poultry. The overall prevalence of Mycobacterium spp. was 2.3% (n=3/130). All the isolates were resistant to Rifampin and sensitive to Azithromycin and Ciprofloxacin. Data of this study indicated that multidrug resistant Mycobacterium spp. are prevalent in the poultry farms of the study area which underscore the need of implementation of good biosecurity to poultry husbandry practice to ensure poultry and human health.http://dx.doi.org/10.5455/javar.2015.b118

This research work was conducted to investigate the effects of age, sex and breed on the induction of immune response against experimentally prepared inactivated trivalent (type O, A, and Asia-1) FMD vaccine. Twenty six cattle were divided into four test groups (Group A, B, C, and D; 5 cattle in each group) and one control group (n=6) based on breed (local and cross), age (?12 months and >12 months), and sex (male and female). Test cattle were vaccinated with the experimentally prepared trivalent FMD vaccine. Pre- and post vaccinated sera from the vaccinated cattle were collected upto 63 days, and the sera were tested using liquid phase blocking enzyme linked immunosorbent assay (LPBE) that was specific for FMD serotypes O, A, and Asia-1. Antibody titers of all the pre-vaccinated serum samples were found to be under protection level. The females were found to be more protected (90%; n=9/10) as compared to males (70%; n=7/10). The titers obtained were statistically analyzed using ttest to observe the effects of age, breed and sex. It was observed that the mean values of antibody titer in cattle aging >12 months against O, A, and Asia-1 serotypes were significant (P<0.05) at 21, 49 and 63 days as compared to the values obtained from the cattle aging ?12 months. In conclusion, the local female cattle aging >12 months showed better immune response towards trivalent FMD vaccine. http://dx.doi.org/10.5455/javar.2015.b121

A cross sectional survey was carried out in dairy farms in four States of Sudan to determine prevalence of reproductive health disorders that affect dairy cattle industries in the country. A total of 575 adult female cows in dairy farms located in Khartoum, Gezira, Sennar, and White Nile States were investigated using questionnaire survey and face-to-face interviews with the owners. The results indicated that 24.4% of the animals were affected with one or more reproductive health disorders. Abortion (57.1%) represented the major health problem affecting calf yield, followed by infertility (34.3%) and neonatal death (8.6%). Other health problems included stillbirth, vaginitis and retained placenta, anomalies, metritis and repeat breeder. Most of the abortion cases were detected during third trimester (76.25%) followed by first (12.5%) and second (11.25%) trimesters. Finally, countrywide investigations of reproductive disorders and increasing awareness to the owners are recommended for designing successful control strategies of reproductive disorders in Sudan. http://dx.doi.org/10.5455/javar.2015.b57

Arsenic is a major water pollutant that may cause serious health hazard (e.g., infertility) in human and animal. We evaluated the changes in histoarchitecture of testes and ovaries of adult Black Bengal goats (n=10) reared in arsenic affected areas in Bangladesh. Grossly, we found insignificant variations among the testes and ovaries, but histological evaluation revealed an extensive alteration in morphology of both testes and ovaries in the arsenic affected goats. In testes, the thickening of tunica albugenia and trabeculae, widening of intertubular space between seminiferous tubules, and narrowing in diameter of seminiferous tubules were observed. In ovaries of arsenic affected goats, significant decrease in number of primary follicles and antral follicles were observed. The diameters of secondary and antral follicles were significantly reduced. The granulosa layer of antral follicles showed marked thickening. The findings indicate that chronic arsenic exposure alters the histoarchitecture of both male and female gonads in Black Bengal goat, and thereby may affect their reproductive performance. http://dx.doi.org/10.5455/javar.2015.b61

Anthrax, caused by Bacillus anthracis is an acute, febrile disease of warm blooded animals including humans. Social norms and poverty in addition to climatic factors such as soil conditions, seasons of year, ambient temperature and rainfall influence the persistence of the B. anthracis and anthrax outbreaks. The present study was designed to reveal the factors influencing the repeated outbreak of anthrax in Bangladesh. Considering the previous outbreaks of anthrax, Sirajganj, Bogra, Kushtia, Tangail and Mymensingh districts of Bangladesh were selected for this study. To elucidate the factors, qualitative data relating to the animal management, knowledge and behavior of the people; and quantitative data relating to soil conditions, ambient temperature and rainfall were acquired, and analyzed critically. Based on the outbreak histories, a year was divided into two seasons, anthrax prone season (May-November) and anthrax dry season (December-April). Anthrax spores could be isolated from 11.67% (n=14/120) of the soil samples collected from the study areas. The present study revealed that poor knowledge, lack of awareness, improper carcass disposal, inadequate vaccination, high Ca content and moisture in the soil along with high ambient temperature and rainfall during the anthrax prone season were the possible influencing factors of repeated outbreaks of anthrax in the study areas. Intensive propaganda to create public awareness of anthrax together with proper vaccination may reduce anthrax outbreaks in Bangladesh. http://dx.doi.org/10.5455/javar.2015.b72

The present work aimed to observe the infection pattern of Bovine herpes virus-1 (BoHV-1) in dairy cattle with reproductive problems in Sudan. A total of 140 samples comprising of vaginal swab (n=97), placenta (n=15), whole blood (n=19), uterine fluid (n=1), and serum (n=8) were collected from 16 dairy herds showing particularly high rate of abortion and infertility in Khartoum State. The samples were used for virus isolation, and were tested by Enzyme-Linked Immunosorbent Assay (ELISA) and polymerase chain reaction (PCR). No virus could be isolated from the samples inoculated for isolation in cell culture. Out of 80 specimens tested by ELISA, 7 (8.75%) were found to be positive, and one sample was doubtful. Using PCR, 11 (10.7%) out of 103 samples were found to be positive. When comparing between two methods for DNA extraction, the DNA extracted by commercial kit was found to be better in quality as compared to the DNA extracted using phenol/chloroform/isoamyl-alcohol method. The study confirmed the presence of BoHV-1 in cattle farms with reproductive problems in Sudan. http://dx.doi.org/10.5455/javar.2015.b81

El-Bahr, Sabry Mohamed | Abdelghany, Ahmed
Three different highly consumed fish species from Al-Ahsa market, Saudi Arabia namely Spangled emporer (Lethriuns nebulosus), Red striped seabream (Pagrus major) and Black seabream (Spondyliosoma cantharus) were evaluated for their muscle contents of heavy metals (e.g., Cd and Pb) and trace elements (e.g., Cu, Zn, Fe and Mn). The possible risks associated with their human consumption were also studied. A total of 60 fresh fish samples comprising of 20 samples from each above mentioned fish were collected, and were subjected for determination of heavy metal and trace element contents by Atomic Absorption Spectrophotometry after Microwave Wet Digestion. The results showed that, accumulation patterns of the heavy metals and trace elements followed the order: Fe > Zn > Cu > Mn > Pb > Cd. There were variations among metal contents in the muscles of the three fish species; S. cantharus accumulated the highest levels of Cu, Zn and Mn, while the highest level of Fe could be detected in the muscles of P. major. The concentration of Cd and Pb remained comparable in the muscles of all three fish species. The calculated maximum daily intake (MDI) values were found as 0.0003, 0.0009, 0.0035, 0.0001, 0.0000, 0.0000 mg/day/person for Cu, Zn, Fe, Mn, Cd and Pb, respectively. Conclusively, the present study indicated that, fish muscles contain relatively less burden of heavy metals and trace elements, and no health problem can be raised from human consumption of the examined commercial fishes at Al-Ahsa market, Saudi Arabia.DOI: http://dx.doi.org/10.5455/javar.2015.b85
