The experiment was carried out to characterize a manipulated caatinga and to estimate the botanical composition and quality of diet for fistulated steers. The experiment was carried out during the rainy season from March to July, 2003. Caatinga was browsed by 24 Guzerá and 12 Girolando breed heifers and by two esophageal fistulated steers. In caatinga, it was identified 24 families, 38 genus, and 41 species in the two studied strata (out of them, ten species were found in the […]

The objective of this study was to evaluate the effect of different doses of liquid swine slurry on dry matter accumulation rate and nutritive values (crude proten and neutral detergent fiber) of Tifton 85 grass pasture cultivated in southwestern Paraná from October 2005 to March 2006. It was used a complete random experimental design in a 4 x 4 factorial scheme composed of four doses of swine slurry in the plots (0, 80, 160 and 320 m3/ha) and four consecutive […]

The objective of this work was to evaluate the morphogenetic and structural characteristics of xaraes palisadegrass submitted to three cutting heights (15, 20 and 25 cm) when the sward reached 95% of light interception during regrowth. The experiment was carried out according to a complete randomized block design with three replications. The sward surface height under the cutting condition of 95% of light interception was very homogeneous with values around 30 cm. The increase in cutting height reduced the leaf […]

Root traits of Panicum maximum Jacq. Cv. Tanzânia were evaluated in response to a nutritive solution with combinations of nitrogen and calcium rates. Ground quartz was used as substrate in an experiment carried out in a greenhouse in the spring, using a complete randomized block design, with four replications, in a fractionated 52 factorial scheme, with 13 combinations of nitrogen and calcium, in mmol/L: 2-0.5; 2-3.0; 2-5.5; 9-1.75; 9-4.25; 16-0.5; 16-3.0; 16-5.5; 23-1.75; 23-4.25; 30-0.5; 30-3.0, and 30-5.5. After the […]

The objective of this research was to evaluate variability and heritability of quantitative traits related to forage quality of 32 clones of elephant grass (three local controls, from Zona da Mata de Pernambuco, and the remaining from RENACE/CNPGL). A complete randomized design was used with additional controls and analyses of variance was applied by using the procedure of families with controls between rows. Evaluation was performed during the dry period, at 60 days of growth. It was observed significant differences […]

The objective of this study is to evaluate morphogenetic and structural characteristics as well as forage accumulation on Brachiaria decumbens pastures according to the site of cattle feces. It was evaluated two grazing areas: near and far from the droppings. The design used was a random block design, with three replicates. Tillers were tagged on the pasture for evaluation of length of the leaves and stems. Leaf appearance and death were also recorded. Stem elongation rate was 80% higher and […]

The performance of beef calves submitted to two weaning ages (early weaning, at an average age of 80 days; conventional weaning, at an average age of 152 days) was evaluated. One hundred and five Braford calves born in 2004 and 2005, after weaning, were kept on pastures cultivated with pearl millet (Pennisetum americanum) in the first and second summer and, in winter/spring, they were kept on pastures with oat and ryegrass (Avena strigosa Schreb + Lolium multiflorum Lam). Body weight […]

The objective of this study is to identify demands of customers of a sire-producing company in Rio Grande do Sul, Brazil, by using a methodology adapted from quality function deployment tool. The adaptation consisted on the fact that matrices are treated in an unified manner among product and services due to the high perception of inter-relationship among these business components. The results evidenced that clients priorize traits related to the product, especially genetic value of the bulls. Service items were […]

The objectives of this research were to analyse data on the international market of frozen boneless beef and to classify its participants into groups according to their trade relationships, identifying the main factors that influence the preference of a country to beef from a determined supplier country. International beef trade is composed of two markets: in one of them, the relationships between supplier and client depend on the lowest price, and Brazil is found in favorable conditions; and the other, […]

The objective of this study was to investigate components of production and seed production of two Paspalum species. It was evaluated two ecotypes of Paspalum notatum and Bagual) and two ecotypes of Paspalm urvillei (André da Rocha and Eldorado do Sul). It was used a complete randomized experimental design, in a factorial scheme (ecotypes x days after planting), with five replicates nested within days after planting. Each species was analyzed separately for determination of the components of production and seed […]
