1. Birds that migrate long distances use stopover sites to optimize fuel loads and complete migration as quickly as possible. Stopover use has been predicted to facilitate a time-minimization strategy in land migrants as well, but empirical tests have been lacking, and alternative migration strategies have not been considered. 2. We used fine-scale movement data to evaluate the ecological role ...

The study was conducted at the Livestock Production Enterprise Bacuranao, of the Habana del Este municipality (La Habana province, Cuba), in order to establish a strategy for the prevention and control of natural intoxications by photosensitizing plants in cattle. For such purpose, a presumptive diagnosis on photosensitization was carried out, through the floristic inventory of the plants prese...

Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access to newly emerged, high quality forage along the green up gradient with increasing altitude; termed the forage maturation hypothesis. Any other limiting factor spatially corre...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

Forage is included in beef cattle growing or finishing diets for several reasons. Nutritionally, forage provides protein, vitamins and minerals. When included as a minor component of high grain finishing diets, forage may increase feed intake and reduce nutritional disorders due to increased salivation, rumination and passage rate. Manipulating dietary moisture content through inclusion of dry ...

APBN1, a variety of hybrid napier was analysed at five stages of harvest (30, 40, 45, 50 and 60 days) for yield, leaf to stem ratio, chemical composition, in vitro dry matter digestibility, in sacco dry matter and protein degradation to find out optimum stage of harvesting. The yield of green fodder, dry matter (DM) and crude protein (CP) (MT/ ha/year) of forage harvested at 30, 40, 45, 50 and ...

The objective of this study was to examine the effect of different forage and supplement combinations on forage and supplement intake and ruminal parameters in steers. Six ruminally fistulated steers were assigned to 1 of 4 treatments during 4 different data collection periods. Treatments were 1) Hay +wet brewers grains (WBG); 2) Hay +dried distillers grains (DDG); 3) round bale silage (RBS) + ...

Overview of Hydroponics Consumption of tomatoes in the United States has reached 4.3 billion pounds each year. When consumers are willing to pay double or triple standard prices for a great tasting, blemish free product, buyers and sellers alike can smile at the possibilities. Repeated pricing studies have shown that only high-quality, garden vegetables, such as tomatoes, cucumbers, salad crops...
