  Effect of single and repeated doses of tramadol on hepatic and renal functions and on pentobarbitone anesthesia was evaluated in dogs. Twenty five dogs were randomly distributed into five equal groups viz groups I and II received 3 mg kg-1 of tramadol by subcutaneous and intravenous injections, respectively during premedication alone. Groups III and IV received similar doses of tramadol during premedication which was repeated 2 h after the initial dose thorough subcutaneous and intravenous injections, respectively. Group V served as negative control. Blood samples (2 mL) were taken at 0, 2 and 4 h after tramadol’s administration while liver and kidney biopsies were taken before the surgery ended. Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels were significantly lowered in groups II-IV when compared to the group V at 4 h. Significant increase in AST was observed in groups I, III and V at 2 h and at 4 h in groups I and V. No significant change in kidney profile. Histopathological changes in the liver and kidney biopsies are mainly congestion, edema and cellular infiltration which occurred less frequently in groups III and IV. The volume of pentobarbitone was significantly lowered in groups III and IV. It is concluded that repeated administrations of tramadol at 3 mg kg-1, IV or SC is safe at a frequency of 2 h interval during surgery without causing irreversible hepatic and renal damage and reduced the required dose of pentobarbitone needed to maintain anaesthesia in healthy dogs.

  The objective of this study was to investigate whether pre freezing and post thawing (motility, morphology, viability, acrosome integrity and membrane integrity). Boer goat spermatozoa are affected by collecting in an Tris citric acid fructose extender supplemented with hypotaurine or cysteine. Semen was collected from four bucks into tubes containing 0 mL extender (Contro I), 2 mL extender without supplementation of antioxidants (Control II), 2 mL extender supplemented with hypotaurine 10 mM and 2 mL extender with cysteine 5 mm. No significant (p>0.05) improvement was observed by adding extender into collection tubes either supplemented or not with antioxidants before freezing and after freeze thawing. While a slight improvement was observed in motility, membrane integrity and acrosome integrity when 2 mL Tris citric acid fructose extender supplemented with either hypotaurine or cysteine. In conclusion, addition of extender in collection tubes either supplemented or not with antioxidants is not beneficial for Boer goat semen cryopreservation.

  The study was carried out to determine the effect of diets containing different parts of Andrographis paniculata on cumulative gas production, dry matter digestibility, methane and volatile fatty acids production in goats using in vitro gas production technique. The leaves, stems and roots of Andrographis paniculata (AP) were analysed for total polyphenols. Leaves of AP were found to contain the highest concentration of polyphenols; 3.08% Tannic Polyphenol (TP), 0.46% Hydrolysable Tannin (HT) and 0.19% Condensed Tannin (CT). The Non-Tannic Polyphenols (NTP) were estimated as 2.43% of the total polyphenols in the herb. Four diets were formulated three of which contained 1% each of the parts analysed (APL = leaves, APS = stems and APR = roots) and not containing Andrographis paniculata (APO) which was used as the control and tested for digestibility via in vitro gas production technique. The results indicated that VFAs, IVDMD, gas production and pH of the rumen fluid were not significantly affected (p>0.05) by the experimental diets except for ammonia (p<0.05). The results suggest that goats can utilize nutrients from feeds containing AP without compromising the production of VFA and dry matter digestibility.

  This study was performed with the aim to evaluate the proximate, elemental and fatty acid analysis of pre-processed edible birdsí nests (Aerodramus fuciphagus) and their comparison between the regions and type of nests. The samples of edible birdsí nests were taken from 5 regions: 4 regions in Penang, Malaysia and one region in Sumatra, Indonesia. The nest type from regions in Penang was house nest, while the one from Sumatra was the cave nest. Analysis of total dry matter content was carried out according to the certification procedures outlined by the Manual of Livestock Feed Analysis, University Putra Malaysia. Crude protein was determined according to the Kjeldahl (micro) method. The fat content of the feed was determined using the total lipid extraction procedure. The crude fibre content of the sample was determined by using an automated apparatus. The elements analyzed in this study were Na, Ca, Mg, K, P and Fe. All of the elements were detected using the Atomic Absorption Spectrophotometer, while for P, PerkinElmer Lambda 35 Spectrophotometer was used. The results showed significant differences in proximate and elemental analysis of edible birdsí nests between the regions and nest types. There were no significant different in the fatty acid content of the nests both between the regions and the nests type. The results also showed that the edible bird-nest have essential components in promoting body vigour.
