1. Fertility Enhancing Potency of Omega-3 Fatty Acids in Male Rats
Abstract Cases of some grave side effects of some allopathic medicines used in treatment of infertility has caused a global need for alternatives with minimal or no side effect, hence the demand to evaluate the fertility enhancing potential of omega-3 fatty acids (O3FA) in male rats. This study evaluated the fertility enhancing potential of omega-3 fatty aci

2. Analysis of daily body weight of dairy cows in early lactation and associations withproductive and reproductive performance
The objective of this study was to describe daily body weight (BW) changes in the first 100 days of lactation in confined dairy cows and to associate BW loss with productive and reproductive performance. Data included 26,344 daily BW measurements of 372 Holsteins calving between June 2011 and June 2012 in a commercial herd in the South of Brazil. Cows were a

4. DINÂMICA DO FÓSFORO NA INTEGRAÇÃO LAVOURA-PECUÁRIA SOB SISTEMA PLANTIO DIRETO / Phosphurus dynamic in crop livestock integration under notillage.
The necessity to preserve the soil, coupled with the constant search for lower production costs and increased productivity resulted in the use no-tillage (NT). Efficient technique in the preservation and use of highly weathered soils (tropical and subtropical soils). However, only the continuous cultivation of monocultures has been implicated in reduced prof

6. CRESCIMENTO, ESTADO NUTRICIONAL E CARACTERÍSTICAS FOTOSSINTÉTICAS DE Bertholletia excelsa SOB TRATAMENTOS DE ADUBAÇÃO EM ÁREA DEGRADADA NA AMAZÔNIA CENTRAL
Human activities on forest ecosystems can result in the removal of forest cover followed by impoverishment of the soil physical, chemical and biological properties. Throughout time, these areas without forest coverage can turn in to degraded areas. In face of this, for the revegetation of these areas with forest species different methods have been applied fo

7. RECOMMENDATION OF PHOSPHATE AND POTASSIUM FERTILIZATION TO THE MAIN GRAIN CROPS UNDER NOTILLAGE IN PARAGUAY / RECOMENDAÇÕES DE FERTILIZAÇÃO FOSFATADA E POTÁSSICA PARA AS PRINCIPAIS CULTURAS DE GRÃOS SOB SISTEMA PLANTIO DIRETO NO PARAGUAI
The recommendations of fertilization have as main purpose to facilitate and aid the decisions about application of fertilizers necessary to obtain yields of maximum economic efficiency. Pointing out the importance of the numerical tables indications, should be also important the crops and area history, the history of fertilizations and calcareous use, the yi

8. Contested dominance modifies the anovulatory consequences of social subordination in female marmosets
Dominance status among female marmosets is reflected in agonistic behavior and ovarian function. Socially dominant females receive submissive behavior from subordinates, while exhibiting normal ovulatory function. Subordinate females, however, receive agonistic behavior from dominants, while exhibiting reduced or absent ovulatory function. Such disparity in

9. Parametros reprodutivos masculinos e fertilidade de ratos adultos expostos ao inseticida fenvalerato / Male reproductive parameters and fertility of adult rats exposed to fenvalerate
Fenvalerate is a synthetic pyrethroid insecticide widely used in agriculture to control a variety of insects. Although it is considered to be of low acute toxicity to mammals, studies have showed that pyrethroids can have estrogenic activity and can act as endocrine disruptors, causing important reproductive impairment in males. It is documented in the liter

10. A queda da fecundidade nas Minas e nos Gerais: um estudo ecológico
The study analyzes fertility decline in 66 microregions of the State of Minas Gerais, over the period 1970-2000. It identifies the factors that eventually influenced this process and by that token, aims to reduce lack of data concerning the transition of fertility at small areas level in Minas Gerais. The fertility decline had similar speed and patterns to t

12. Soil fertility and 137Cs redistribution as related to land use, landscape and texture in a watershed of ParaÃba state / Fertilidade do solo e redistribuiÃÃo de 137Cs em funÃÃo da cobertura vegetal, relevo e classes texturais, em uma microbacia hidrogrÃfica do estado da ParaÃba
Intensive land use and growing deforestation of the natural vegetation in Northeastern Brazil have contributed to the degradation of resources, particularly the decrease of soil fertility. As a result, biodiversity and ecosystem capacity to restore its resources after disturbances have been diminished. The decrease in soil fertility is more substantial in ar
