Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (P<0.05) in B. indicus a...

A new species of spider crab, Sunipea callistus, n. sp., from Cape Guardafui, Somali Republic, is described and illustrated. Sunipea indicus (Alcock, 1895) is also redescribed and figured. Sunipea callistus n. sp. differs from S. indicus in the structures of the carapace, third maxillipeds, thoracic sternum, male abdomen, and chelipeds. Despite a number of characteristics that separate both spe...

Heat stress has negative effects on pregnancy rates of lactating dairy cattle. There are genetic differences in tolerance to heat stress; Bos taurus indicus (B. t. indicus) cattle and embryos are more thermotolerant than Bos taurus taurus (B. t. taurus). In the present study, the effects of sire and sire breed on conception and embryonic/fetal loss rates of lactating Holstein cows during the Br...

Greater than half of the cattle in the world are managed in tropical environments, while approximately 40% of beef cows in the United States are located in subtropical areas. Furthermore, approximately 80% of global beef production is Bos indicus based. Given this, Bos indicus germplasm plays a critical role in both US and worldwide beef production particularly when used as part of a well-struc...

Many scientists have worked out on the host-parasite relatiosship. The cestode parasites were attached mostly in the stomach and duodenal mucosa. Heavy infection with this cestode parasites caused inflammation, congestion(Khadap,2009). Lytocestus indicus is a caryophyllaeid cestode of fresh water fishes. During the present study on the helminth parasites of the fresh water fishes of Warangal, C...

Our objective was to estimate Bos primigenius taurus introgression in American Zebu cattle. One hundred and four American Zebu (Nellore) cattle were submitted to mtDNA, microsatellite and satellite analysis. Twenty-three alleles were detected in microsatellite analysis, averaging 4.6 ± 1.82/locus. Variance component comparisons of microsatellite allele sizes allowed the construction of tw...

In the current review the main fundamental biological differences in reproductive function between Bos taurus and Bos indicus cattle are discussed. Breed differences regarding puberty, estrous cycle patterns, estrous behavior, acquisition of ovulatory capacity, ovarian structures and reproductive hormones are presented. The main physiological differences that Bos indicus cattle present relative...

The rhizome of Java grass, Cyperus rotundus was extracted different organic polar and non-polar solvents and performed the in vitro antiviral and immunostimulant activities against White Spot Syndrome Virus (WSSV) and Vibrio harveyi respectively. Based on the initial screening the ethyl acetate extract of C. rotundus was strong activities and further it was purified through silica column chroma...

The giant water bug, Lethocerus indicus (Lepeletier and Serville) (Heteroptera: Belostomatidae), a native species of Southeast Asia, is one of the largest insects belonging to suborder Heteroptera. In this study, the meiotic chromosome of L. indicus was studied in insect samples collected from Thailand, Myanmar, Loas, and Cambodia. Testicular cells stained with lacto-acetic orcein, Giemsa, DAPI...

Treatment of rats with paracetamol and CCl4 produced a significant increase in the levels of serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total and direct bilirubin. Rats pretreated with methanolic extract of roots of H. indicus (100-500 mg/kg body weight, po) exhibited rise in the levels of these enzymes but it was ...
