The effect of feeding system on fattening performance,slaughter, and carcass characteristics of Norduz male kids

The study was conducted to determine the effect of feeding systems on fattening performance, slaughter, and carcass characteristics of male Norduz kids. In the study, 20 male Norduz kids weaned at 2.5 months of age were divided into two groups after weaning. The first group was reared under semi-intensive conditions (SI) on a mixture of pasture and concentrate, and the second group was reared under extensive conditions (E) on pasture only. SI group had higher final weight (35.30 kg versus 32.81 kg), daily weight gain (153.10 g versus 132.14 g), and warm carcass yield (44.84% versus 46.55%) compared to the E group although there were no significant differences. Body organs, carcass parts, prime cuts, and chemical composition of the chop area did not also differ in two groups significantly. As a conclusion, this study showed that semi-intensive feeding systems improved kid fattening performance and carcass characteristics.

Immune response in rams experimentally infected with Brucella ovis

Cellular as well as humoral immune responses were detected in six rams experimentally infected with Brucella ovis. Specific antibodies were detectable by enzyme-linked immunosorbent assay by day 11 after infection in all the rams. The levels of IgM antibodies and total antibodies in the serum rose until 33 and 41 days after infection respectively, then levelled off. Antigen-induced blastogenic responses by lymphocytes developed as early as five days after infection in all rams but had decreased to low levels by day 63 in most. Blastogenesis induced by phytohaemagglutinin and concanavalin A varied among infected rams and did not differ significantly (P greater than 0.05) from control rams. All rams had developed delayed-type skin hypersensitivity by day 63 after infection. One ram which did not become infected as a result of exposure had low levels of B ovis serum antibodies and a detectable antigen-induced lymphocyte blastogenic response before infection, suggesting the involvement of cell-mediated immunity in protection against B ovis.     

Corynebacterium pseudotuberculosis infection and lymphadenitis (taloa or mala) in the camel

Summary Pure cultures ofCorynebacterium pseudotuberculosis were obtained from 11 cases of lymphadenitis (known locally as taloa or mala) in camels. Camel isolates produced typical taloa in camels experimentally inoculated subcutaneously at the base of the external ear with 10¹⁰ colony forming units. A sheep strain ofC. pseudotuberculosis inoculated into camels produced a local abscess at the site of inoculation but did not produce taloa. Re-infection of camels recovered from experimental inoculation did not produce taloa suggesting the possibility of the development of a vaccine against lymphadenitis in camels.

Infeccion PorCorynebacterium Pseudotuberculosis Y Linfadenitis (Taloa O Mala) En El Camello

Resumen Se obtuvieron cultivos puros deCorynebacterium pseudotuberculosis a partir de 11 casos de linfadenitis (conocida localmente como taloa o mala) en camellos. La inoculación subcutánea en camellos en la base de la oreja de 10¹⁰ unidades formadoras de colonias procedentes de un cultivo obtenido de camellos infectados causó taola. Sin embargo, una cepa ovina deC. pseudotuberculosis causó un abceso en el lugar de la inoculación pero no produjo taola en camellos. La reinfección de los camellos que se habían recuperado de la inoculación experimental no causó taola, lo que sugiere la posibilidad de desarrollar una vacuna frente a la linfadenitis caseosa del camello.

Infection ACorynebacterium Pseudotuberculosis Et Lymphadenite (Taloa Ou Mala) Chez Le Chameau

Résumé On a obtenu des cultures pures deCorynebacterium pseudotuberculosis à partir de 11 cas de lymphadénite (dénommée localement taloa ou mala) chez des chameaux. L'inoculation expérimentale des isolements camelins faite en infection sous-cutanée à la base de l'oreille externe avec 10¹⁰ unités formant des colonies a provoqué un taloa typique. Une souche ovine deC. pseudotuberculosis inoculée à des chameaux n'a conduit qu'à la formation d'un abcès local au point d'inoculation mais pas au taloa. La réinfection des chameaux guéris d'une inoculation expérimentale ne provoque pas de taloa, ce qui permet d'augurer la possibilité de développement d'un vaccin contre la lymphadénite cameline.

     

A wavelet analysis-based approach for damage localization in wood beams

Free vibration testing was conducted to generate the first two mode shapes for damage detection in timbers. A wavelet transform was proposed to postprocess the mode shapes for damage pattern recognition. The wavelet used here was “db3.” The different damage severities, damage locations, and number of damaged areas were simulated by removing mass from intact beams. The results showed that the chosen wavelet db3 is suitable and that the wavelet coefficients are sufficiently sensitive to identify the existence of damage and its location in cases of different damage location, severity, and number. An edge distortion effect was apparent at the two computing edges where the wavelet coefficients were abnormally high. The wavelet coefficients showed dominant spikes around the damage locations and were zero everywhere else except the two computing edges. The dominant spikes coincided well with the damage location.     

Effect of induced pyrexia on the disposition kinetics of ciprofloxacin in dogs

Ciprofloxacin was administered intravenously @ 5 mg/kg body weight to six healthy dogs. After a washout period of two weeks, fever was induced by injecting Escherichia (E) coli endotoxin. Ciprofloxacin was administered again. Blood samples were collected at various time intervals and analyzed for ciprofloxacin with HPLC. The kinetic analysis revealed the volume of distribution in healthy vs. febrile dogs as 2.12 ± 0.32 vs. 1.79 ± 0.43 L/Kg, respectively. The elimination half life was 2.23 ± 0.78 and 2.07 ± 0.74 hours in healthy and febrile dogs, respectively. Similarly, dogs under healthy and febrile conditions showed comparable total plasma clearance of 0.66 ± 0.06 and 0.60 ± 0.07 L/Kg/h, respectively. All these and other investigated kinetic parameters were statistically non significant. This study concludes that the pharmacokinetic behavior of ciprofloxacin is similar under healthy and febrile conditions. Thus, the kinetic studies of fluoroquinolones conducted in normal/healthy animals may be used to depict the pharmacokinetic parameters in diseased animals.     

Effect of breed on fattening performance, slaughter and meat quality characteristics of Awassi and Morkaraman lambs

The influence of breed on fattening performance, slaughter and meat quality traits was studied in Awassi and Morkaraman male lambs at approximately 8 months of age. All of the groups were fed a diet consisting of concentrate mixture offered ad libitum, and 300 g of grass hay per lamb per day during 60-day fattening period. Initial live weight, final live weight, daily weight gain and feed conversion efficiency (concentrate and hay consumption for 1 kg of live weight gain) were 39.63 kg, 55.08 kg, 0.258 kg and 6.37 for Awassi; 40.54 kg, 55.58 kg, 0.234 kg and 6.77 for Morkaraman, respectively. The effect of breed on fattening performance and slaughter traits except for LD area was not significant. In addition, meat colour parameters (L = lightness, a = redness, b = yellowness, H = hue angle and C = chroma), pH values, drip loss and sensory attributes were not affected by breed in present study. A significant muscle effect was observed for instrumental measurements of some meat quality characteristics as meat colour parameters (L, a and C), collagen, drip loss, pH, moisture and protein content, WBS, and for some sensory attributes (tenderness, juiciness, acceptability and number of chewing). Results of this study indicate that fattening performance, slaughter and meat quality traits were similar between Awassi and Morkaraman male lambs.     

First record of Oomyzus scaposus (Hymenoptera: Eulophidae), as a parasitoid of Coccinella septempunctata (Coleoptera: Coccinellidae) in Pakistan

Coccinella septempunctata L. (Coleoptera: Coccinellidae) is a natural enemy of several important pests. This biocontrol agent is also a host for different parasitoids. Little is known about the parasitoid complex of C. septempunctata in Pakistan. The authors identified Oomyzus scaposus (Thomson, 1878) (Hymenoptera: Eulophidae) as a larval-pupal parasitoid of C. septempunctata in the district of Sargodha, Punjab, Pakistan. Out of 36 C. septempunctata pupae collected, 58.3% were parasitized by O. scaposus. This study documents the first record of O. scaposus parasitizing C. septempunctata in Pakistan.
