allergen levels in the spring, consistent with findings seen in the classroom. Interestingly, the presence of a basement did not predict higher classroom allergen levels as would be expected andwas only associated with higher cafeteria airborne levels. Similar to previous studies, the reported presence of mice in homes was predictive of higher mouse allergen levels.5,6 However, home allergen le...

Problem statement: Poultry industry is intensive and consistently applies an all-in, all-out system with the aim of minimizing infection pressure and targeting specific pathogens like Salmonella which remains one of the leading causes of food-borne illness, many questions regarding the introduction and persistence in animal production still remain.

Accurate estimations of nutrient digestion and retention are critical in nutrient balance and feed evaluation studies because errors that occur are often additive. However, there is no standard universal method for drying feces, urine, or excreta before laboratory analysis. The objective of this study was to evaluate the impact of 4 different drying methods on nutrient concentrations in feces, ...

In order to domesticate the freshwater oyster Etheria elliptica, a 42-day pond rearing trial was conducted in two ponds of equal size (12 m2 x 1.10 m deep), one which fertilized with poultry droppings and other control (unfertilized). Three depths (30 cm, 60 90 cm from bottom pond) were tested repetition. For each depth, 02 sieves (40 diameter 15 depth) used. A total 180 oysters an average 37.5...

Abstract Developments in polymer technology have introduced new choices such as using fibers and fiber-reinforced polymers (FRP) to improve the impact behavior of concrete structures. In this research, 52 samples (half which wrapped with glass polymers-GFRP) different compressive strengths (20, 30, 40 MPa) polypropylene were constructed. These subjected weight dropping (46.7 kg 66.8 kg). The nu...

High population growth and growing income lead to increasing demand for poultry products in Nigeria. The poultry industry has emerged as the most commercialized and fastest expanding segment in the animal husbandry subsector but still faces many problems. Private investment from foreign countries could help to facilitate this market. This paper reveals the opportunities and threats of a market ...
