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 […]

This study aimed to evaluate four sources of phosphorus for cattle grazing African Bermudagrass (Cynodon nlemfuesis Vanderyst) pasture and to compare them considering weight performance and physiological parameters. It was used a complete random experimental design, with 32 crossbred steers (Bos indicus x Bos Taurus) at average initial weight of 347 kg randomly distributed in four groups, each one receiving mineral supplement formulated with dicalcium phosphate, supertriple phosphate, monoammonium phosphate or Araxá rock phosphate, as sources of phosphorus. Weight gain […]

The objective of this study was to estimate tissue composition of the carcass from physical composition of commercial cuts of F1 crossbred goats (Boer with females of non-defined racial standard) finished on native pasture with four levels of supplementation with concentrate (0.0; 0.5; 1.0 and 1.5% of BW in dry matter). It was used 24 non-castrated animals at initial body weight of 15.52 kg and at 120 days of age. The carcass was sectioned in the half, and from the […]

The objective of this work was to estimate the total recovering and the long term bias of the estimates of fecal excretion using the external markers chromic oxide and titanium dioxide and internal markers indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) in a digestion assay with cattle fed different diets. Fourteen F1 Red Angus x Nellore averaging 12 months and 287 kg were used. The animals were fed with elephant grass silage, […]

It was used 27 goat kids (18 ¾ Boer + ¼ Saanen and nine Saanen; 18.0 ± 1.60 kg) distributed in a completely randomized design with factorial arrangement to evaluate productive performance and the total digestibility of dry matter and nutrients in the rations. Diets were composed of soybean meal, soybean meal + dry yeast or dry yeast as protein source, oat hay, ground corn and vitamin-mineral mixture with mean composition of 2.50 Mcal of ME/kg DM and 17.0% of […]

The objective of this study was to evaluate carcass traits through ultrasonography in real time and after slaughter and the relationship between these traits and carcass yields of lambs with different genotypes finished in feedlot with several levels of energy in the diet. It was used 54 non-castrated lambs: 18 pure Santa Inês (SI), 18 ½Dorper x ½Santa Inês (Dp x SI) and 18 ½Santa Inês x ½ Without Standard Defined Breed (SI x WSDB), at an average age of […]
