Última NUTRIENTS BALANCES IN BEEF CATTLE PRODUCTION SYSTEMS AND THEIR IMPLICATIONS FOR THE ENVIRONMENT R.C. Suelo Nutr. Veg. Alfaro,M; Salazar,F. S; Oenema,O; Iraira,S; Teuber,N; Ramirez,L; Villarroel,D. The main inputs and outputs of nitrogen (N) and phosphorus (P) in soils and swards under typical Southern Chilean conditions were determined between 2004-2005 and 2006-2007 to establish soil and field gate N and P balances under different immediate stocking rates (63 and 191 anim ha-1 d-1) and field slope treatments (4 and 12%). Treatments received 67.5 and 40 kg N and P ha-1 yr-1 as inorganic fertilizer. The main N and P input to the soil balances was N mineralization (304 kg ha-1 yr-1) and inorganic fertilizer (62 and 69% for N and P, respectively). The main output for all treatments was plant uptake (95% and 100% on average for N and P, respectively). The N and P apparent use efficiency was high (>95%). The main N and P input to field gate balances... Tipo: Journal article Palavras-chave: Stocking rate; Field slope; Grazing; Nutrient budget.

Agric. Res. Alfaro,Marta; Salazar,Francisco; Iraira,Sergio; Teuber,Nolberto; Villarroel,Dagoberto; Ramírez,Luis. In Chile there is little information on nutrient losses in livestock systems. The experiment was carried out between 2004 and 2006. Two stocking rates (3.5 and 5.0 steers ha-1) were tested under rotational grazing with Black and White Friesian steers on a permanent pasture (67.5 kg N and 40 kg P ha-1 yr-1). To quantify surface runoff losses (N, P, K), three surface lysimeters (5 x 5 m) per treatment were established. N and K leaching losses were estimated with ceramic cups. Runoff and leachate samples were individually analyzed for available and total N, reactive (RP) and total P, and K. Dissolved organic N (DON) and organic P (OP) were estimated as the difference between total and available forms. The stocking rate did not increase total N, P and K losses...

Bras. Zootec. Almeida,Paulo José Presídio; Pereira,Mara Lúcia Albuquerque; Silva,Fabiano Ferreira da; Santos,Alana Batista dos; Pereira,Taiala Cristina de Jesus; Santos,Edileusa de Jesus dos; Moreira,Jeruzia Vitória. This study was conducted with the objective of evaluating the effect of concentrate supplementation, formulated with different ingredients (Mesquite pod meal, sorghum meal or wheat meal and mineral supplementation) on performance, intake and digestibility of nutrients in Santa Inês lambs grazing on urochloa grass during the dry season. Twenty-four uncastrated weaned Santa Inês sheep, with average body weight (BW) 20±2 kg with an average of 120 days of age were used in the assay. The experiment lasted 75 days. The animals grazing deferred Urochloa grass (Urochloa mosambicensis (Hack) Daudy) were distributed into four treatments consisting of mineral supplementation provided ad libitum and concentrated supplements containing mesquite pod meal, sorghum meal...

Stocker cattle ownership is compared to contract grazing using stochastic simulation. Returns are evaluated for both cattle owners and caretakers in contract grazing agreements. For caretakers, contract grazing is significantly less risky than cattle ownership. Slightly to moderately risk-averse caretakers could be expected to prefer some type of contract grazing to direct ownership of cattle. For cattle owners, contracting reduces risk only slightly while significantly reducing expected returns.

Using monocultures or single species dominated natural phytoplankton, cell counts and volume estimations obtained by visual and electronic methods show reasonable agreement.Calibration seems possible (Figs.1-2).2. Further examples given (Fig. 3-4) show that microscopical identification of the volume peaks in electronic counter spectra of natural seston is not quite simple. Phytoplankton peaks may not be detected in the Counter spectrum. Shifts of Counter peaks to the left side of the visual spectrum may be found when cylindrical, elongated or needle- like phytoplankton dominate the sample.3. Both visual and electronic methods include potentially large errors. Possibly particle volume is either overestimated by the microscope and / or underestimated by...

G.; MARTHA JÚNIOR, G. B.. Planning forage needs in beef cattle enterprises is necessary for efficient utilization of genetic and environmental resources in pastoral systems and to generate economic benefits in an environmentally sound way. Production risk evaluation is essential in feed planning for cow-calf operations in pastoral systems. The proposed method to accomplish with production risk in these systems is based on the time biological system is maintained in an acceptable state under adverse climate conditions. This is coined "buffering time". The buffering time is calculated for both animals and pasture using an energetic approach. For cows, the buffering time is the minimum period the animal takes to reach the lowest acceptable body weight. for pasture, it is period for...

Soils under pastures suffer physical modifications, in greater or lesser intensity, via the action of animal trampling. Thus, the aim was to evaluate the spatial dependence of soil physical attributes under bovine trampling. The trial was performed at Roçadinho Farm, Agreste of Pernambuco, Brazil, in a 40 x 40 m paddock that was managed with continuous stocking by bovines and 12 AU ha-1 stocking rate. Soil samples were collected before and after grazing using a 6 x 6 m grid, totaling 36 sampling points. At each point, the bulk density, total porosity, moisture, soil penetration resistance at 0.00 - 0.10, 0.10 - 0.20, and 0.20 - 0.30 m depth were estimated, as was the hydraulic conductivity on the saturated soil surface.

Even though wetlands are very valuable environments, they suffer heavy exploitation and transformation processes that affect their biodiversity. The main goal of this study was to characterize the herbaceous plant communities associated with the southern Uruguay River flood plain. We focused on lowlands of two farms, one of which is surrounded by an embankment to prevent flooding. A random stratified sampling was performed in 72 plots. To detect distribution patterns and plant species associations we performed a Detrended Correspondence Analysis (DCA) and a Two-Way indicator species analysis (TWINSPAN). We could identify six groups of plots whose ordination patterns are related to the flooding preferences of dominant species. Herbaceous plant groups that...

A cultura do feijão-miúdo tem crescido em importância na região de clima temperado, principalmente em áreas da agricultura familiar, utilizando sistemas de base ecológica, visando a alimentação de ruminantes. Na região da planície costeira do Rio Grande do Sul a cultura apresenta grande desenvolvimento e tem se espalhado mais recentemente para outras áreas, no entanto sem informações técnicas sobre o seu manejo. A rusticidade da planta é reconhecida largamente, vegetando bem em solos mal drenados, arenosos e de baixa fertilidade, salinos e com baixa disponibilidade de água, sendo especialmente indicada como recuperadora de solo. Sua multiplicidade de usos tornou-a uma importante opção aos agricultores familiares, podendo ser utilizada além de recuperadora...

The ingestive behavior of crossbred heifers grazing on stargrass pasture was managed at two levels of light interception and two levels of post-grazing residual height. The experiment was conducted at Pesagro (Seropédica, Rio de Janeiro State) between April 2012 and January 2013. The grazing (GT), rumination (RT) and idling (IT) times were evaluated every 10 minutes throughout a 24-hour period. Forage samples were collected for the analysis of chemical composition and for leaf:stem ratio determination. Dry bulb, wet bulb and black globe temperatures were evaluated every hour along with the relative humidity, during grazing to characterize the environment and calculate the Black Globe Humidity Index (BGHI).
