AIM In Senegal, uncontrolled cross-breeding of cattle breeds and changes in production systems are assumed to lead to an increase of gene flow between populations. This might constitute a relevant threat to livestock improvement. Therewith, this study was carried out to assess the current genetic diversity and the phylogenetic relationships of the four native Senegalese cattle breeds (Gobra zeb...

The present study examined the prevalence and genotypes of Cryptosporidium andersoni in cattle in Shaanxi province, China. A total of 2071 fecal samples (847 from Qinchuan cattle and 1224 from dairy cattle) were examined for the presence of Cryptosporidium oocysts, and 70 samples (3.4%) were C. andersoni-positive and those positive samples were identified by PCR amplification of the small subun...

Investigating the Mental Health Status and Its Related Factors among Students of Guilan University Medical Sciences

Farmers play a key role in conserving native livestock breeds, but without economic support, farms with breeds may not be viable. We hypothesized that terminal crossbreeding can improve herd economy and decrease the support needed from society. Three scenarios were simulated using SimHerd Crossbred: of purebred Swedish Polled Cattle, Red, 75% Cattle 25% F1 crossbreds. The results showed annual ...

background: mixed infection with amphistomes seems common in native cattle of iran. the aim of this study was to determine diagnostic antigens in cattle mixed amphistomiasis. methods: specific antigens of cotylophoron cotylophorum , gastrothylax crumenifer and paramphisto­mum cervi (mixed infection), the most common species, were collected from cattle was deter­mined. adult trematodes were coll...

Measuring the level of awareness for sustainable development in rural construction (Case Study: Guilan Architecture)

Rice product after wheat has special importance as the second agriculture strategic product. Rice weevil as one of the most important stored pest has the main role in losses of stored product. So in this research, the pest effects was studied on 4 common varieties of rice in Guilan province "Taroum, Hashemi, Ali kazemi and Dylamani" in two conditions of facultative and obligatory nutrition. Res...

Acinetobacter species have been reported as opportunistic pathogens. Here, we report the draft genome sequence of Acinetobacter sp. HR7 isolated from the rumen of cannulated Korean native cattle (Hanwoo; Bos taurus coreanae).

BACKGROUND The geographical incidence of IBD varies considerably. This study aimed to survey the epidemiologic features of IBD in Guilan province, North of Iran, during ten years duration. METHODS In this retrospective cross-sectional study, we assessed the documents of 868 patients with IBD referred to private and governmental clinics of Guilan province between 2002 and 2012. Variables such as...

The objective of this study was to develop emission factors (EF) for methane (CH4) emissions from enteric fermentation in cattle native to Benin. Information on livestock characteristics and diet practices specific to the Benin cattle population were gathered from a variety of sources and used to estimate EF according to Tier 2 methodology of the 2006 Intergovernmental Panel on Climate Change (...
