2. Challenges to increase the AI and ET markets in Brazil
Abstract Artificial insemination (AI) and embryo transfer (ET) are the most widely used biotechnologies in the world with the goal of increasing genetic gain and improving reproductive efficiency of beef and dairy herds. The protocols for ovulation synchronization for timed AI (TAI) or ET (TET) are tools that allow artificial insemination or transfer of a hi

3. Modelling beef cattle production systems from the Pampas in Brazil to assess intensification options
ABSTRACT Traditional livestock productivity is hard to estimate, since it depends on a gamut of animal production indicators that are difficult to measure for many farms. Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Br

4. Production and quality of the silage of corn intercropped with Paiaguas palisadegrass in different forage systems and maturity stages
ABSTRACT The objective of this study was to evaluate dry matter production, fermentative parameters, and nutritional value of the silage of corn intercropped with Paiaguas palisadegrass in different forage systems and maturity stages, in the off-season. The experiment was carried out in a randomized block design, with four replications, in a 5×3 factorial a

5. Sustainable productive intensification for family farming in developing tropical countries
RESUMO No passado, a agricultura era direcionada para satisfazer as necessidades humanas. Hoje em dia, é direcionada para atender os mercados, forçando o campesinato a se adaptar a essa condição. Como resultado, os agricultores familiares se tornaram multifacetados, incorporando tanto a produção de subsistência quanto aquela orientada para o mercado.

6. Growth and chlorophyll in noni seedlings irrigated with saline water in substrate with vermicompost
RESUMO A irrigação é um fator limitante para o desenvolvimento das culturas, e todas as fontes de água contem sais, podendo acumular-se no solo e na planta, comprometendo seu desenvolvimento. Dentre algumas alternativas para atenuar os efeitos negativos dos sais nos vegetais está a utilização de vermicomposto, sendo este um adubo orgânico condicionad

8. Common moist diet replacement to promote sustainable Cobia Rachycentron canadum (Linnaeus) near- shore farming in Brazil
ABSTRACT: Cobia is one of the most promising warm water aquaculture species. In Brazil, cobia farming began in 2008 in the state of Rio de Janeiro from experimental scale facilities to regular near-shore farms based on fresh/frozen fish diets composed mostly of Sardinella sp. Despite the encouraging results achieved in the promotion of sustainable cobia farm

9. Producción subjetiva sobre la exposición a agroquímicos. Revisión de la bibliografía científica
Abstract The intensification of agriculture in countries of the Southern Cone of Latin America has led to a significant rise in the use of agrochemicals. Scientific output in the field of health has concentrated on the epidemiological aspects of this issue and studies addressing the social dimensions of exposure to these substances remain scarce. The aim of

12. Soil carbon stock and humification in pastures under different levels of intensification in Brazil
ABSTRACT: Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification. Pastures in four beef cattle produc
