Study on the Comparative Efficacy of Natural Growth Promoter (AV/AGP/10) with Antibiotic Supplements on Overall Growth Performance and Intestinal Micrometry of Broiler Birds.

Aims: The study was conducted to compare the efficacy of natural growth promoter AV/AGP/10 with antibiotic supplements on overall growth performance and intestinal micrometry of broiler birds. Study Design: Total of 150 healthy day old Vencob broiler chicks of nearly similar live body weight were equally divided into 5 groups of 30 birds each with three replicates in each group. All the groups were fed with basal diet. Group-I was positive control without any supplement, Group- II was supplemented with AV/AGP/10 @ 250g/ton of feed, Group- III supplemented with AV/AGP/10@500g/ton of feed, Group-IV supplemented with Bacitracin Methylene Dicyticylate @100g/ton of feed and Group-V supplemented with Oregostim @ 250g/ton of feed. Place and Duration of Study: the study was conducted in the department of Animal Nutrition, College of Veterinary and Animal sciences, Udgir, Dist. Latur, Maharashtra, India during the month of April- June 2012 for 42 days. The mean maximum daily temperature recorded at the time of trial was 41±2ºC and relative humidity (RH) 80.57 ± 1.50 %. Methodology: the efficacy of the products was assessed on the basis of feed consumption, body weight gain, feed conversion ratio (FCR), metabolic trial / nutrient retention trial, intestinal micrometry and carcass yield / dressing percentage. Results: at the end of sixth week, significantly higher live body weight (1874.19, 1921.51, 1720.39 and 1673.58) with more economical FCR (1.74, 1.71, 1.78 and 1.78) along with marked improvement in digestibility of nutrients from supplementation of herbal growth promoter with equal competence as that of synthetic antibiotic was observed. The intestinal micrometry at day 21 and 42 also revealed better results with natural growth promoter as compared to synthetic growth promoter and control group in terms of villous height, width and crypts depth. Conclusion: Considering the overall trial results and harmful effects of antibiotic growth promoter such as bacterial resistance or undesired residues in animal products, the natural product AV/AGP/10 is better option as growth promoter and performance enhancers in broiler birds.

Trichuris vulpis (Froelich, 1789) Infection in a Child: A Case Report

We present a human infection with the canine whipworm, Trichuris vulpis, in a child suffering from rhinitis with a diagnosis of rhinitis. T. vulpis eggs resemble those of T. trichiura but they can be differentiated based on their morphological features and egg size, using micrometry with an ocular micrometer. T. vulpis eggs measured an average of 90 microm by 44 microm (range 86-99 microm by 38-47 microm). Prevalence of hookworms (28.1%), Toxocara canis (11.8%), and Trichuris vulpis (3.5%) was found in 292 fecal samples of dogs collected at the peri-domicile, which showed that the risk of infection was not only fortuitous. The treatment of canine whipworm infections is similar to that of T. trichiura infection. We recommend differentiation of the 2 species for their epidemiological and prevention implications.

Comparative intestinal histomorphology of five species of Phyllostomid bats (Phyllostomidae, Microchiroptera): ecomorphological relations with alimentary habits / Histomorfometría comparativa de intestino de cinco especies de murciélagos Phyllostomideos (Phyllostomidae, Microchiroptera): relaciones ecomorfológicas con hábitos alimentarios

The intestines of Sturnira lilium, Phyllostomus hastatus, Carolliaperspicillata, Glossophagasoricinaíind Desmodus rotundus were analized through macroscopic, morphometric and light microscopy studies. The species studied presented some common charactenstics generally found in bats, such as the absence of a caecum and an appendix. The frugivorous bat S. lilium has a longer intestine than the other species. The intestinal epithelium is of the simple columnar type, constituted of absorptive cells characterized by microvilli and goblet cells, which in all the species proved to be PAS + and AB +. These cells presented some differences in quantity and in distribution among the species. The intestinal mucosa presented morphologic and morphometric differences, such as the shape and size of villi as well as the length of the crypts of Lieberkühn. Histologically the different intestinal portions could be distinguished: in the middle portion we found few goblet cells and long villi; in the distal portion we found an increase in goblet cells and a decrease in villi height; and in the large intestine no villi were found, but rather abundant intestinal glands with numerous goblet cells. In C. perspicillata, P. hastatus and G. soricina we could observe Peyeras patches in the distal portion near the large intestine, whereas in D. rotundus and S. lilium we found aggregations of lymphoid nodulous tissue distributed along the tube. In all species we observed the presence of Paneth cells at the base of the crypts of Lieberkühn. We could observe differences among the species in the distribution of collagen in the small intestine submucosa and serosa. The outer muscular layer has one circular layer and a longitudinal layer, the circular layer increasing in thickness along the tube. Large intestine charactenstics are uniform among the species. Sfractures such as the taenia coli and the appendices epiploicae were absent. These results should contribute not only...

Los intestinos de Sturnira azucenas, Phyllostomus hastatus, Carollia perspicillata, Glossophaga soricina y Desmodus rotundus se analizaron a través de estudios macroscópicos, morfométricos y de microscopía de luz. Las especies estudiadas presentan algunas características comunes en general encontradas en murciélagos, tales como la ausencia de un ciego y un apéndice. Murciélagos frugívoros S. azucenas tienen un intestino más largo que el de otras especies. El epitelio intestinal es de tipo columnar simple, constituido por células de absorción que se caracterizan por microveilosidades y células caliciformes, que en todas las especies resultó ser PAS + y AB +. Estas células presentan algunas diferencias en cantidad y en la distribución entre las especies. La mucosa intestinal presenta diferencias morfológicas y morfométricas, como la forma y el tamaño de las vellosidades, así como la longitud de las criptas de Lieberkühn. Histológicamente las diferentes partes intestinales pueden ser distinguidas: en la parte media encontramos pocas células caliciformes y largas vellosidades, en la porción distal encontramos un aumento de células caliciformes y una disminución en la altura de vellosidades, y en el intestino grueso no se encontraron vellosidades, sino más bien abundantes glándulas intestinales con numerosas células caliciformes. En C. perspicillata, P hastatus y G. soricina podemos observar placas de Peyer en la porción distal, cerca del intestino grueso, mientras que en D. rotundus y S. azucenas se encontraron agrupaciones de tejido linfoide nodular distribuido a lo largo del tubo. En todas las especies se observó la presencia de células Paneth en la base de las criptas de Lieberkühn. Hemos podido observar diferencias entre las especies en la distribución de colágeno en el intestino delgado y submucosa serosa. La capa muscular exterior tiene una capa circular y una capa longitudinal, la capa circular en el aumento de espesor a lo largo del...

The Effect of Spinal Cord Injury on Spermatogenesis in Rats / 대한비뇨기과학회지

Male infertility occurs after spinal cord injury (SCI). However, little is known about the effect of SCI on male reproductive function. We evaluated objective assessment of spermatogenesis of spinal cord injured rats by quantitative micrometry and DNA flow cytometry analysis at various time intervals. SCI was produce(B in 30 rats by 710 spinal cord transection. Controls received similar surgery without transaction. From 10 randomly selected seminiferous tubules per subject the mean number of mature spermatids, Sertoli cells, tubular diameter and tubular wall thickness were determined in both groups. The percentage of haploid, diploid and tetraploid cells were determined of each subject by DNA (low cytometry, Two way analysis of variance (ANOVA) was performed. In the SCI rats the mean number of spermatid per tubule was significantly lower (p=0.01) than that of controls. The mean number of Sertoli cells per tubule was not different from that of controls. Mean of spermatid to Sertoli cell ratio per seminiferous tubule in SCI rats was significantly lower than in controls (p=0.048). No significant differences of tubulr wall thickness, diameter and percentage of haploid cells were noted between both groups. These results suggest that the effect of SCI on spermatogenesis is associated with inadequacy of spermatid formation and maturation delay of spermatid.
