The kouprey is a rare and enigmatic forest ox discovered by scientists in Cambodia only in 1937. Numerous morphological hypotheses have been proposed for the origin of the kouprey: that it is a species closely related to banteng and gaur, two other wild oxen of southeast Asia; a morphologically divergent species placed in a separate genus, named Novibos; a wild species linked to aurochs and dom...

The ultrastructure of normal, ejaculated spermatozoa of Bos indicus was studied by means of electron microscopy, being evaluated in two principal parts, the head and the tail. The head is flat, oval or paddle-shaped with a square base, which provides a concave recess for the insertion of the tail. The acrosome tightly covers the anterior two thirds of the nucleus. A distinct unilateral acrosoma...

The major histocompatibility complex (MHC) plays well-defined roles in eliciting immune responses and combating infectious diseases. The major histocompatibility complex of cattle is referred to as BoLA (Bovine Lymphocyte Antigen). This genetic system is among the most polymorphic. In the present study, polymorphism of the BoLADRB3.2 locus in three Bos indicus breeds viz., Sahiwal, Rathi and Ha...

N has a high level of biocultural diversity that has brought many researchers to the country for centuries. There exist many reports about their studies and explorations that describe Nicaraguan cultures, languages, and ecosystems. Nonetheless, terrestrial fauna has been significantly under-represented in these investigations and subsequent publication. Due to this, there is a great deal regard...

Tangius indicus sp. n. (Batrisitae: Batrisini) is described and illustrated from the Indian States of Meghalaya (Khasi Hills, type locality) and West Bengal (Darjeeling). Specimens of the new species are similar to those of the recently described T. glabellus Yin & Li from Tibet, Southwest China, and can be separated only by minor differences of the male features.

Trypanosomiasis remains a major constraint to the development of livestock in Sub-Saharan Africa and a big part of Africa is rendered unsuitable for the production of livestock due to the presence of tsetse flies. A cross sectional study was conducted to estimate the prevalence of trypanosomosis in Mulanda Sub County, Tororo district in Eastern Uganda during the month of April 2014. Whole blood...

A severe outbreak of dermatophilosis occurred in 1985 in a herd of Brahman cows imported from Martinique in Guadeloupe in July 1983. Little was known on this disease in Guadeloupe until then, for the local zebu breed is naturally highly resistant to diseases transmitted by ticks or associated with them. Conditions of appearance and development of the disease were studied in relation with herd m...

Plasma progesterone concentrations were determined weekly during gestation averaging 283 +/- 2 d in Ethiopian zebu (Bos indicus) cows. Mean progesterone levels increased from 0.2 +/- 0.1 ng/ml at oestrus (service) to 3.1 +/- 1.6 ng/ml on d 7 and 8.1 +/- 2.1 ng/ml on d 21. Progesterone levels remained elevated throughout pregnancy. Hormone concentration differed significantly between cows (P les...
