OBJECTIVE To determine pharmacokinetics of butorphanol tartrate incorporated into poloxamer 407 (P407) after SC administration to Hispaniolan Amazon parrots (Amazona ventralis). ANIMALS 11 adult Hispaniolan Amazon parrots (6 males and 5 females; 11 to 27 years old). PROCEDURES A sterile formulation of butorphanol in P407 (But-P407) 25% (percentage determined as [weight of P407/weight of diluent] × 100]) was created (8.3 mg/mL). Five preliminary experiments (2 birds/experiment) were performed to determine the ideal dose for this species. The formulation then was administered (12.5 mg/kg, SC) to 8 birds. Blood samples were collected before (time 0) and 0.08, 0.5, 1, 2, 4, 8, 12, and 24 hours after drug administration. Some birds were used more than once, with a washout period of ≥ 3 months between subsequent treatments. Butorphanol concentrations were quantitated by use of liquid chromatography-tandem mass spectrometry. Pharmacokinetic analysis was performed by use of noncompartmental analysis. RESULTS Maximal plasma butorphanol concentration was reached at 1.31 hours. Plasma concentrations of butorphanol remained > 100 ng/mL for > 3 hours (all birds) or > 4 hours (5/8 birds) but < 8 hours (all birds). Half-life of the terminal slope was 3.41 hours. No adverse effects were detected. CONCLUSIONS AND CLINICAL RELEVANCE Butorphanol was absorbed well from the But-P407 25% by Hispaniolan Amazon parrots, and absorption followed a pharmacokinetic profile compatible with a sustained-release drug. A dose of 12.5 mg/kg, SC, would theoretically provide analgesia for 4 to 8 hours. No adverse effects were detected. Studies on the pharmacodynamics of this formulation are necessary to confirm the degree and duration of analgesia.

In most countries, poultry are reared by traditional farmers d ue tothe relative minimum capital needed to start off, availability of feed and the fast period of the birds to grow. This research was conducted on turkeys which aims to study the abundance and prevalence of ectoparasites from three localities around Kedah, Malaysia. Atotal of 20 turkeys (eight males and twelve females) were examined for ectoparasites infestation and endoparasites infection.Six species of ectoparasites: five lice and a mite have been discovered. The most prevalent ectoparasite was Menopon gallinae with occurrence of 45%. Other external parasites recorded includeLipeurus caponis and Megninia cubitalis with occurrence of 40%, Menacanthus pallidulus (35%), Goniocotes gallinae (30%) and Chelopistes meleagridis (20%). There was a significant difference between the ectoparasite abundance in Jabatan Perkhidmatan Veterinar and Alor Belat Barat [ANOVA, F(2,17)=6.33, p=0.009]. These lice commonly found in the fluff of the feathers, especially at the neck,abdomen, and wings. Lipeurus caponis was found to have the highest infestation in all male and female turkeys and Menacanthus pallidulus was noted as the less common ectoparasite infesting both the male andfemale turkeys. Endoparasite infection was recorded in two species of parasite eggs of nematodes and protozoa. Oocyst of Eimeria spp. recorded the highest faecal egg count with 7300 epg compared to Capillaria spp. with only 1200 epg. Scavenging and pecking behaviour of turkeys in barn area with unsuitable farm housing environmentwere the major contributing factors to the infestation of ectoparasites as well as endoparasites infection.

2017
Gani, M. U. | Siddiqui, M. S. I. | Islam, K. | Ahmed, S. | Rashid, M. H. | Moonmoon, S. | Mostofa, M.
The study of alterations of some hematological parameters in a experimentally induced lead toxicosis were carried out on a total of 15 (15 days old) male weaning Long- Evans (ICDDRB strain) rats. The rats were randomly divided in to three equal groups, each consisting of fiverats. Rats of group A were kept as control (without giving any treatment), group B received lead acetate alone @ 6 mg/ml drinking water and group C receivedlead acetate @ 6 mg/ml plus whole milk (Star ship®) 150 mg/ml drinking water. The result showed a most significantly (p< 0.01) decreased TEC, TLC and Hb%observed on day 56 in group B but in group C, these counts decreased significantly (p< 0.05) on days 56 of experiment. From the study, it was concluded that treatment with lead acetate at low doses has harmfuleffects on experimental animals including hematological alterations.

A comprehensive study was conducted on the clinical observationsincluding clinical history, physical examination along with haematobiochemical alteration on 41 naturally occurring cases of canine babesiosis from Punjab state, India. Examination of 964 dogs revealed 4.25 percent (41/964) prevalence of the disease including 3.84 percent (37) B. gibsoni and 0.41 percent (4) B. canis infected cases. Clinical and parasitological diagnosis was finally confirmed by polymerase chain reaction. A large variation of clinical anifestations including rare findings of paraplegia, blindness, ocular bleeding, immune mediated haemolytic anaemia (IMHA), ascites and skin lesions were observed among the affected animals. Bloodfilms showed anisocytosis and nucleated erythrocytes indicating regenerative anaemia. Blood parameters of the affected dogs revealed significant decrease in Hb, TEC, PCV and thrombocytes. Significantdecrease in lymphocytes was found in B. gibsoni affected animals. The affected dogs showed significant increase in serum bilirubin, ALT, AKP, BUN and creatinine. Haemato-biochemical observations wereindicative of severity of babesiosis in dogs.

Salmonella is known as one of the important food-borne pathogenthat causes salmonellosis in human and animals worldwide. A prevalence study on salmonellosis was conducted on wild rats in Kelantan. From April to June 2015, a total of 36 rats and house shrews sent to the Regional Veterinary Laboratory in Kota Bharu, Kelantan were examined for the presence of Salmonella. These animalswere caught from various locations in the state and were sent to the laboratory either as live or dead specimens. Post mortem wasconducted and intestines were taken for detection of salmonellosis. Results showed that of the 32 rats and 4 shrews examined, 5 (15.6%) rats and 3 (75%) shrews were found positive and on serotyping fourserotypes of Salmonella were identified which are Salmonella ser. Kalamu (62.5%), Salmonella ser. Thyphimurium (12.5%), Salmonella ser. Weltevreden (12.5%) and Salmonella ser. Brancaster (12.5%). In conclusion, positive identification of Salmonella in wild rats indicates that there is a possible transmission of the pathogento humans due to constant contact between the two. Thus appropriate measures are needed to control these pests population to prevent spread of diseases to the humans and animals.

A classification of raw bovine’s milk samples according to theirgeographical origin in Peninsular Malaysia by Makmal Kesihatan Awam Veterinar, Department of Veterinary Services Malaysia (DVS). Six hundred bovine milk samples were collected from Perlis, Kedah, Perak, Selangor, Pahang, Negeri Sembilan, Melaka and Johor states by 26 milkcollecting centres under DVS. This study was carried out directly using attenuated total reflectance Fourier transform infrared(ATR-FTIR) spectroscopy method coupled with a multivariate principal component analysis (PCA). The spectra generated by ATR-FTIR were analysed and regions of interest were found in between 3851.651cm-1 until 2700.819 cm-1 and 2419.173 cm-1 until 977.368 cm-1. The absorbance and wavenumber data of the regions were then analysed using PCA and the results show presence of clustering towards theirgeographical origin. ATR-FTIR coupled with multivariate PCA has potential for classifying the geographical origin of raw milk produced within Peninsular Malaysia. This method provides a rapid and nondestructive secondary methodology in milk classification without further sample preparation.

2017
Muhammad Syafiq I. | Selvaneswary K. | Suhaimi D. | Wan Syahidah H. | Normah M.
This study was conducted to observe the occurrence of aflatoxin in chicken feed from Peninsular Malaysia. A total of 336 samples of chicken feed from Peninsular Malaysia were conveniently collected in this survey. The chicken feed represented the following three categories which are starter, grower and finisher. All samples werecollected from local poultry farms in East Coast Region (Kelantan, Terengganu, and Pahang), Northern Region (Perlis, Kedah, Penang, and Perak), Southern Region (Malacca, Johor) and Central Region (Selangor, Negeri Sembilan) of Peninsular Malaysia for a periodof six months (July-December 2015). Enzymelinked immunosorbent assay (ELISA) was used for screening of total aflatoxin (TA) in the samples. High performance liquid chromatography (HPLC) with fluorescence detector was used for determination of aflatoxin B and G. Moisture content of samples was determined using the hot airoven method (AOAC International, 2011). Overall, the incidence of positive TA >20 µg/kg in chicken feed is 14.9% (50 samples). The average level of TA was found significantly different between different states at p<0.05 for both broiler grower and finisher. Thechromatograph results showed that positive samples were found in broiler finisher from Kedah (94.6 µg/kg and 42.1 µg/kg) and Penang(56.4 µg/kg) with aflatoxin B1. In this study, the range of moisture content were around 6.5-27.3%. About 40% samples have more than12% moisture content. One of the predisposing factors for aflatoxin accumulation in chicken feed is moisture content. The results warrantthe need for surveillance and constant monitoring programmes for the prevention of aflatoxin incidence in poultry farms.
Mostrar más [+] Menos [-]A quantitative investigation of knowledge and practices of human brucellosis in Kajiado County, Kenya
2017
Maina, A. G. | Gatongi, P. M. | Nguhiu, P. N.
Human brucellosis, a neglected zoonosis is endemic in KajiadoCounty in both man and livestock. The Kajiado County community’s mainlivelihood is livestock-keeping which puts it at risk. The study objective was to determine the community’s knowledge and practices, and the association between the two in relation to brucellosis. Results revealed three predictors of practices the community undertook that put them at risk of contracting brucellosis. The predictors were respondent’s education status (p=0.002 [CI 0.272-0.749] OR 0.451), knowledge of importance of pre-purchaselivestock breeding soundness (p=0.007 [CI 1.207-3.356] OR 2.013), and knowledge that livestock abortions could result in human disease (p=0.027 [CI 1.070-2.974] OR 1.783). This meant that respondents without formal education were nearly half less likely to undertake practices that prevented transmission of brucellosis than those withformal education. Respondents who knew that livestock examination was important for breeding soundness were twice more likely to engage in practices that prevented brucellosis transmission than those whodid not know. Respondents who knew that livestock abortions could lead to diseases in man were nearly twice more likely to engage in practices that prevented transmission of brucellosis than those whodid not know that livestock abortions could lead to diseases in man. It was concluded that the community’s knowledge and practices that promote brucellosis were inadequate. Two key recommendationswere drawn. There was need to create awareness in the community on the risk factors and practices that contribute to occurrence of human brucellosis. There was need for using qualified animal health providers to mitigate the disease in animals.

Gan, S. H. | Ong, S. P. | Chin, N. L. | Law, C. L.
This paper presents the resultsof an experimental attempt to improve thedrying kinetics for the retention of colourand sialic acid in edible bird’s nest throughheat pump drying. Kinetics of hot air dryingand heat pump drying were studied byperforming various drying trials on ediblebird’s nest. Isothermal drying trials wereconducted in hot air drying and heat pumpdrying at a temperature range of 40 °C-90 °C and 28.6 °C-40.6 °C, respectively.Intermittent drying trials were carried outin heat pump drying with two differentmodes, which are periodic air flow supplyand step-up air temperature. Experimentalresults showed that heat pump drying withlow temperature dehumidified air not onlyenhanced the drying kinetics but alsoproduced a stable final product of ediblebird’s nest. Heat pump-dried edible bird’ssamples retained a high concentration ofsialic acid when an appropriate dryingmode was selected.
