Many consumers have been looking for increasingly safe foods, without agrochemicals, as those produced in organic systems. An alternative to this is the use of techniques that minimize the use of agrochemical inputs. Thus, this study aimed to evaluate the effect of cow urine application on the performance of radish crops. The experiment was carried out in Tangará da Serra, Mato Grosso, Brazil. The experimental design was a randomized block with five treatments and four replications. The treatments employed were: Organomineral leaf fertilizer (Platon-25®) and four doses of cow urine (0 mL; 35 mL; 70 mL and 105 mL). The variables evaluated were: tuberous root diameter, tuberous root length, shoot fresh mass, root fresh mass, tuberous root weight, root length. Application of cow urine, regardless of dose, influenced significantly radish development. At the 70 mL dose of cow urine, the plants showed the same development as those that received the application of organomineral fertilizer. Cow urine provided better radish performance when compared to organomineral fertilizer for most of the variables analyzed, showing that for the conditions of the study, the 105 mL dose of cow urine can be used as a foliar biofertilizer in the radish crop. Muchos consumidores han estado buscando alimentos cada vez más seguras, sin agroquímicos, como los producidos en sistemas orgánicos. Una alternativa a esto es el uso de técnicas que minimizan el uso de insumos agroquímicos. Por lo tanto, este estudio tuvo como objetivo evaluar el efecto de la aplicación de orina de vaca en el rendimiento de los cultivos de rábano. El experimento se llevó a cabo en Tangará da Serra, Mato Grosso, Brasil. El diseño experimental fue un bloque aleatorizado con cinco tratamientos y cuatro repeticiones. Los tratamientos empleados fueron: fertilizante organomineral de las hojas (Platon-25®) y cuatro dosis de orina de vaca (0 mL; 35 mL; 70 mL y 105 mL). Las variables evaluadas fueron: diámetro de la raíz tuberosa, longitud de la raíz tuberosa, masa fresca del brote, masa fresca de la raíz, peso de la raíz tuberosa, longitud de la raíz. La aplicación de orina de vaca, independientemente de la dosis, influyó significativamente en el desarrollo del rábano. Con la dosis de 70 mL de orina de vaca, las plantas mostraron el mismo desarrollo que las que recibieron la aplicación de fertilizante organomineral. La orina de vaca proporcionó un mejor desempeño del rábano en comparación con el fertilizante organomineral para la mayoría de las variables analizadas, mostrando que para las condiciones del estudio, la dosis de 105 mL de orina de vaca se puede utilizar como biofertilizante foliar en el cultivo de rábano. Muitos consumidores têm buscado alimentos mais seguros, sem agroquímicos, como aqueles produzidos em sistemas orgânicos, uma alternativa para isso é a utilização de técnicas que minimizem o uso de insumos agroquímicos. Dessa forma, objetivou-se com este trabalho avaliar o efeito da aplicação da urina de vaca sobre o desempenho da cultura do rabanete. O experimento foi realizado no município de Tangará da Serra, Mato Grosso, Brasil. O delineamento experimental utilizado foi em blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos empregados foram: fertilizante foliar organomineral (Platon-25®) e quatro doses de urina de vaca (0 mL; 35 mL; 70 mL e 105 mL). Foram avaliadas as variáveis: diâmetro da raiz tuberosa, comprimento da raiz tuberosa, massa fresca da parte aérea, massa fresca das raízes, peso da raiz tuberosa, comprimento das raíz. Verificou-se que a aplicação da urina de vaca, independentemente da dose, influenciou significativamente o desenvolvimento do rabanete. Na dose de 70 mL de urina de vaca as plantas apresentaram desenvolvimento igual as que receberam a aplicação do fertilizante organomineral. A urina de vaca proporcionou melhor desempenho do rabanete quando comparada ao fertilizante organomineral para a maioria das variáveis analisadas, mostrando que, para as condições do estudo, a dose de 105 mL de urina de vaca pode ser utilizada como biofertilizante foliar na cultura do rabanete.

Eight crossbred Holstein-Zebu lactating cows with average body weight 525 +/- 18.5 kg and average milk yield of 8 +/- 1.45 kg day(-1) were assigned to four treatments (diets) in a double-Latin square design, as follows: a diet based on corn- and soybean meal-based concentrate and three diets with 20% inclusion of byproducts from the biodiesel industry (cottonseed cake, sunflower meal, and castor bean cake) on a total dry matter basis. The cows were housed in individual covered stalls with concrete floor equipped with individual concrete troughs for feeding and automatic drinkers, and fed diets containing 60% sugarcane and 40% concentrate. The inclusion of the byproducts in the diet changed the intake, digestibility of some nutritional components, milk yield and composition, and feeding behavior of lactating cows. The use of cottonseed cake and sunflower meal in the diet increased milk yield, and fat-corrected milk yield; while the use of castor bean cake reduced the intake, digestibility of dry matter and total digestible nutrients, milk yield, and fat-corrected milk yield. The inclusion of byproducts from the biodiesel industry in the diets did not change the fat, lactose, total solids, and solids-not-fat of milk. Therefore, the cottonseed cake and sunflower meal can be included at up to 20% of the total diet.

The present study aimed to evaluate the fermentation kinetics and degradation rates of Cynodon grasses estimated by semi-automated technique of in vitro gas production. The forages were: Coastcross, Tifton 85 and Tifton 68. Pressure readings were taken at 0, 2, 4, 6, 8, 10, 12, 15, 19, 24, 30, 36, 48, 72 and 96 hours. Dry matter degradability (DMD) was obtained by the percentage of dry matter (DM) remaining after 0, 6, 12, 24, 48 and 96 hours of fermentation. Tifton 85 showed a higher total gas production (p
