13. Growth and reproductive performance of 14- to 15-month-old Hereford heifers
ABSTRACT Aiming at breeding heifers with 14-15 months of age, 100 Hereford calves were subjected to different feeding systems. Heifers grazed on a natural pasture in early winter, fed or not a supplement (14% crude protein; 72% total digestible nutrients), were transferred to a ryegrass pasture for 73 days, and then returned to a natural pasture for 15 days

14. Abundance and Diversity of Soil Macrofauna in Native Forest, Eucalyptus Plantations, Perennial Pasture, Integrated Crop-Livestock, and No-Tillage Cropping
ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied:

15. Forage accumulation in brachiaria grass under continuous grazing with single or variable height during the seasons of the year
The objective of this study was to evaluate grazing management strategies of Brachiaria decumbens cv. Basilisk managed with different heights under continuous grazing with cattle. Two grazing management strategies were evaluated: maintenance of pasture with an average height of 25 cm throughout the experimental period and maintenance of pasture on the averag

16. Performance of Braford steers grazing on cultivated pastures and fed or not fed an energy supplement
This experiment evaluated the performance of 84 Braford steers grazing on summer and winter cultivated pastures fed or not fed an energy-protein supplement. Steers were 10 months old and weighed, on average, 165 kg at the beginning of the trial. Steers grazed on cultivated winter pasture, consisting of black oats (Avena strigosa) and ryegrass (Lolium multifl

17. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

18. Nitrogen and carbohydrate fractions on Tifton-85 pastures overseeded with annual winter and summer forage species in different seasons
An experiment was conducted during the 2001-2002 winter-spring-summer to determine the nitrogen and carbohydrate fractions in Tifton-85 pastures exclusively or overseeded with oats, millet and sorghum-sudangrass hybrids. The treatments were Tifton-85 overseeded with millet + bristle oat; sorghum-sudangrass + bristle oat, on 06/19/2002 and 07/02/2002, respect

19. Quality of the forage apparently consumed by beef calves in natural grassland under fertilization and oversown with cool season forage species
The objective of this study was to evaluate the chemical composition of the forage apparently consumed by steers in a natural grassland on region of Campanha, in Rio Grande do Sul, Brazil, subjected or not to different inputs: NP - natural pasture without inputs; FNP - fertilized natural pasture and INP - improved natural grassland with fertilization and ove

20. Carcass characteristics and meat quality of Aberdeen Angus steers finished on different pastures
The present study was conducted to assess carcass features, physicochemical and sensory parameters of meat from steers finished on three types of pastures: natural pasture; natural pasture improved, fertilized and oversown with winter species; and annual summer grassland. The experiment was conducted from December 14, 2009 to November 30, 2010, with treatmen

21. Production and quality of milk from Mantiqueira dairy cows feeding on Mombasa grass pasture and receiving different sources of roughage supplementation
Production and quality of milk from dairy cows grazing exclusively on Mombasa grass pasture, during the spring-summer period and fed roughage supplementations, during the autumn-winter, were evaluated in two consecutive years. The pasture of 11.4 ha was divided into 57 paddocks of 2,000 m² each, including three replications with 19 paddocks each. The pastur

22. Natural and improved pastures on growth and reproductive performance of Hereford heifers
This study evaluated yearling growth and reproductive performance of Hereford heifers at 24-26 months of age grazing on natural pastures at two stocking rates during winter and spring, associated or not to improved natural pastures. Heifers were classified according to three weight groups (Light, Medium and Heavy) and randomly distributed into four feeding m

23. Atributos físicos do solo, produção de biomassa e balanço energético em sistema de integração lavoura-pecuária leiteira sob plantio direto / Soil physical attributes, production of biomass and energy balance in system integration crop livestock dairy in tillage
The integrated crop-livestock allow a series of advantages, but the intensive land use without technical criteria regarding the grazing pressure and machinery traffic can bring damage to soil physical quality, as manifested by compression. In these more intensive systems of production there is growing concern in relation to energy balance. The large amount o

24. Parâmetros produtivos do uso de pastagens temperadas irrigadas na terminação de bovinos de corte / Productive parameters in irrigated pastures use in the finishing beef cattle
The productive parameters of the three production pasture system irrigated based (S1, S2 and S3) in the finishing beef cattle were evaluated at South Brazil. The experimental period was from October, 2010 until September, 2011. The pasture growth (PG; KgDM/ha/d), forage accumulate (FA; KgDM/ha), stocking rate (SR; kgLW/ha/y), animal performance (ADG; kg/an/d
