<p class="abstract"><strong>Background:</strong> Increasing the bird’s wealth and increasing the growth rate are among the goals of increasing the animal wealth so; we studied the effects of L-carnitine and calf thymus extract on growth performance and immunity in broiler chickens.</p><p class="abstract"><strong>Methods:</strong> Eighty broiler chicks were divided into four groups, each group included twenty chicks. Group 1, was negative control with no treatment of feed or water. Group 2, the regular drinking water was replaced by L-carnitine-infused water (1 gram per liter). Group 3, the regular drinking water was replaced by calf thymus extract- infused water (1 ml per liter). Group 4, the regular drinking water was replaced by both L-carnitine and calf thymus extract- infused water. This treatment was administered from day 1 to day 30 of the cycle. Body weight, feed intake and feed conversion were assessed. The hemogram, leuckogram, total protein, globulin, albumin, phagocytic activity, phagocytic index and interleukin 2 were measured. </p><p class="abstract"><strong>Results:</strong> The hemogram and leuckogram parameters recorded a significant increase in treated groups compared to non treated group. The final body weight for all treatments was nearly the same, but slightly higher with application of L-carnitine. Phagocytic activity, index, TP, globulin and IL2 were significantly increased in treated groups.</p><p class="abstract"><strong>Conclusions:</strong> Both L-carnitine and thymus extract have significantly improved the general health condition, in addition, calf thymus extract improved not only the general body condition but also act has immunomodulatory effect which require more further studies.</p>
Skin burns are one of the most difficult medical problems. Recently, studies have been directed towards development of natural products in order to identify effective and safe remedies. In the present study, we evaluated the efficacy of a natural composite (formulated from honey and essential oils) compared with MEBO® (0.25% β-sitosterol) and DERMAZIN® creams (1% silver-sulfadiazine) in the treatment of thermally induced skin burns. For this purpose, four burn-wounds were created on the back of male New Zealand rabbits (n = 10) using a thermal stamp under the effect of general anesthesia. Each wound represents one of the following groups: non-treated, natural composite-cream, MEBO®-cream, and silver-sulfadiazine treated groups, respectively. Treatments were applied once a day topically until one of these wounds appeared to be healed grossly. The non-treated group received no treatment. Grossly, skin burns have been healed after 28 days of the treatment in all groups except of the non-treated group. The healing efficacy of the natural composite, MEBO® and silver-sulfadiazine creams was quite similar macroscopically. However, microscopically, the epidermal layer of the composite-cream treated group was more mature than those of both MEBO® and silver-sulfadiazine creams treated groups. In conclusion, the tested composite may be a promising effective and inexpensive treatment of skin burns.
Background: Nonsteroidal anti-inflammatory drugs and antibiotics are commonly prescribed together. We aimed to study the kinetic profile of cefquinome (2 mg/kg b.wt.) following intramuscular administration of it alone and co-administered with meloxicam (0.2 mg/kg b.wt.) in goats.Methods: Five Egyptian Baladi goats, each goat was injected intramuscularly at the dose rate of 2 mg/kg b.wt. Cefquinome into the deep gluteal muscle of hindquarter alone and then after fifteen days washout period, these animals also injected intramuscularly at the dose rate of 2 mg/kg b.wt. Cefquinome preceded with meloxicam at the dose rate of 0.2 mg/kg b.wt. The serum concentrations of cefquinome were detected by high performance liquid chromatography, two compartment model.Results: Following a single dose intramuscular administration of cefquinome alone, peak plasma concentration (1.71±0.0189 μg/ml) was obtained at 1.59±0.0038 h. The absorption half-life (t1/2ab), total body clearance (Cltot), elimination half-life (t1/2el) and area under curve (area under concentration (AUC(0-inf)) of cefquinome were 0.4±0.0028 h, 0.068±0.78 l/h/kg, 9.21±0.178h and 29.36±0.78 µg.h.ml-1, respectively. Following a single dose intramuscular co-administration of cefquinome and meloxicam, peak plasma concentration (1.60±0.0124 μg/ml) was obtained at 1.49±0.0092 h. The absorption half-life (t1/2ab), total body clearance (Cltot), elimination half-life (t1/2el) and area under curve (AUC(0-inf)) of cefquinome were 0.396±0.006 h, 0.094±0.25 l/h/kg, 6.5±0.221 h and 21.38±0.696 µg/h/ml, respectively. Non significant alters were reported in the parameters following co-administration of Cefquinome with meloxicam.Conclusions: From our results, may be concluded that intramuscular administration of meloxicam may be successfully co-administrated with cefquinome for combating bacterial infections with an inflammatory condition in goats without any antagonistic effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
