to determine the effect of hen age and storage condition on egg quality, fresh eggs were sampled from two commercial flocks of white leghorn hens at 28 and 68 weeks of age. half of sampled eggs from each flock were stored at 6°c and the other half was stored at room temperature. fifteen eggs were randomly sampled from each treatment following collection and at 5-day intervals to 30 days of stor...

P rotein has long been the favored macronutrient for athletes. The logic is simple: if you want big muscles and muscle is made of protein, then eating more protein equals more muscle. This simple rationale is more fiction than fact, but it is difficult to convince athletes that protein is not the most important nutrient for sports performance. Flip through the pages of any health and fitness ma...

study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...

Beekeepers experience high annual losses of colonies, with environmental stressors like pathogens, reduced forage, and pesticides as contributors. Some factors, nutritional stress from flower abundance or diversity, are more pronounced in agricultural landscapes where extensive farming limits pollen availability. In addition to affecting other aspects colony health, quantity quality available i...

Fish egg quality is strongly related with the ability of to be fertilized and develop a normal embryo good survival lack abnormalities. Large variations in spawning quantity or impact directly competitiveness sustainability hatcheries, which create an overly large broodstock order satisfy on-growing companies’ demand for undeformed fry. The present study reports, first time relation gilthead se...

The paper addresses the two-fold rise in teacher-student ratio in the American K-12 school system in the post-World War II period accompanied by the evidence of a decline in the relative quality of teachers. We develop a dynamic general equilibrium framework for analyzing the teacher quantity-quality trade-off and offer an explanation to the observed trends. Our OLG model features two stages of...

Any discipline of human knowledge is characterized by three fundamental elements: the complexity of its content, the method used for its elaboration, and the language used for its expression. This article argues that any method for making knowledge is a particular combination of three main components that we can call (a) science, (b) art, and (c) revelation. The right combination depends on the...

This inequality is especially critical for Asia, which has 60% of the world’s population but only 36% of the world’s water. Water quality in terms of pollutant loading also is not distributed equally and is related to the type of use and a country’s level of development (Figure 2). Developing countries often have less capacity to improve water quality and depend on lower-quality water for a var...
