An experiment was conducted to evaluate the productive performance and carcass characteristics of three groups of growing grasscutters fed home-made concentrate diets. The objective was to assess the feeding values of the diets. The diets were labelled 0% grass diet, 7.5% grass diet and 15% grass dietand respectively contained 0, 7.5 and 15% guinea grass, Panicum maximum. The completely randomi...

knowledge of the warming or cooling effects induced by asphalt or grass covered areas, may improve our understanding of how thermal stress or thermal comfort is created for workers who have to work outdoors for long hours in warm seasons. for this purpose a field measurements were carried out to know the cooling and warming effects of two adjacent areas, one covered with grass and the other wit...
Invasive species can alter the succession of ecological communities because they are often adapted to the disturbed conditions that initiate succession. The extent to which this occurs may depend on how widely they are distributed across environmental gradients and how long they persist over the course of succession. We focus on plant communities of the USA Pacific Northwest coastal dunes, wher...
In Florida, horses have numerous arthropod pests. Most of these pests are considered external parasites as their attack on the horse is principally external, as opposed to internal parasites such as “worms” or nematodes and bots.

The grass carp (Ctenopharyngodon idella) is one of the most important freshwater fish species in China and the world; grass carp production accounts for about 16% of the world’s total freshwater aquaculture [1]. In 2015, Wang et al. performed whole-genome sequencing and de novo assembly for a female (0.9 Gb) and male grass carp (1.07 Gb) by using the shotgun sequencing strategy [2]. Based on th...
the major lymphoid tissues in teleost fish are the kidneys, thymus, spleen and mucosa-associatedlymphoid tissue including the skin, gills and intestine. the head of kidney (pronephros) is an importanthaematopoietic organ and has morphological similarities with the bone marrow in higher vertebrates. in thisstudy, during 12 months from august 2002 to july 2003, 120 grass carp (10 fish/month) were...
