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...

Studies on the trypanotolerance of Orma Boran X Maasai Zebu (Orma Zebu) crossbred cattle (F1 progeny) and pure-bred Maasai Zebu contemporaries were carried out in Nguruman, south western Kenya. The two groups were monitored from birth for a period of 2 years. The incidence of trypanosomosis, parasitaemia, packed cell volume (PCV), body mass and average daily mass gain were monitored. During the...

The embryo recovery following superovulatory (SOV) treatment using equine chorionic gonadotrophin (eCG) and porcine follicular stimulating hormone (FSH) in native Rathi (Bos indicus) cattle was studied. In treatment I (n=33) 2000 IU of eCG was injected on day 8 of the natural estrus. In treatment II (n=17) donors received six 12 h im descending doses of porcine FSH (Super OV, Ausa International...

Milk production data from Holstein × Zebu cows in small farms (2.4 cows per farm on average) in Maharashtra, India, followed by Bharatiya Agro Industries Foundation (BAIF), an Indian non-governmental organisation, were analysed to evaluate the impact of simplified milk-recording systems. The aim was to investigate, in developing tropical areas, less-costly protocols compared with the one curren...

The objective of the study was to evaluate the maternal protective behavior of zebu-type cattle (Bos indicus) and its association with temperament. A total of 40 cow-calf pairs raised under extensive conditions were randomly assigned to 1 of 4 groups (n = 10), which were evaluated at 30, 60, 90, and 120 d postpartum (dpp), respectively. Measures obtained were defense responses of cows protectin...
