This work was carried out to characterize agronomically birdsfoot trefoil (Lotus corniculatus L.) genotypes, including eight populations derived from the cultivar São Gabriel, one rhizomatous cultivar (ARS-260) and one cultivar without rhizomes (Trueno). Individual plants were submitted to seven cuts under field conditions during one year, at Passo Fundo, Rio Grande do Sul, Brazil. The genotypes showed variability relative to internode lenght, height, diameter, legume lenght, forage production and nutritive value. On the average, the populations and the cv. Trueno […]

This experiment was carried out with 22 anestrus Gir cows (Bos indicus), with the postpartum follicular growth studied in 15 of these suckling and kept on pasture, while the seven others were used only for hormonal treatments. Daily real time ultrasonography was done from 4th to the 50th day, using B-mode ultrasound scanner equipped with a linear array 5.0MHz probe. No animal showed estrus, ovulation or follicular luteinization during de experimental period. Four to eight follicular waves emerged each six […]

This experiment was carried out in a greenhouse at the Animal Science Department/UFRPE and aimed to evaluate the fertilization and nematicide effects on the chemical composition of cactus forage cv. “Gigante” suffering chlorotic symptoms. Chlorotic cladodes of Cactus forage cv. “Gigante” were used as planting material and they were collected at the Caruaru Experimental Station/IPA in the same location where those symptoms were previously observed. The treatments tested the presence or absence of macronutrients, micronutrients, and nematicide. A completely randomized […]

The objective of this experiment was to evaluate the yield and carcass characteristics of steers from the following four genetic group: Nellore (N), F1 Canchim x Nellore (CN), F1 Limousin x Nellore (LN) and F1 Aberdeen Angus x Nellore (NA). For this purpose, 32 steers, with age of 19 months and live weight average of 558 kg, raised in confinement and fed diet with and without protected fat for 166 days, were slaughtered. A completely randomized design, with four replicates, […]

Two experiments were conduct to evaluate the effect of dietary nutritive value and performance of sheep fed corn- or sunflower silage-based diet with increasing concentrate proportion (20, 40 and 60%). A factorial design (2×3) was used to evaluate nutritive value and digestibility coefficient of two silages with three concentrate levels and three sheep for each treatment. For lamb performance, a randomized block design in a factorial arrangement (2×3) was used to evaluate lamb performance, with five Suffolk lambs/treatment. Apparent digestibility […]

This study was conducted to evaluate the influence of humidity levels at harvesting period and drying temperatures of wheat grain in isoprotein, isoenergy and isovolumetric diets on broiler performance. The wheat grains were harvested with 30, 16 and 13% of humidity levels and submitted to drying temperatures of 100, 70 and 40°C. The level of 13% of humidity was not submitted to drying. The diets were offered to birds in three distinct periods, 1-21; 22-35 and 36-42 days of age. […]

One experiment was conducted to study the utilization of animal by-products in broilers diets based on the concept of crude and ideal protein form 43 to 49 days of age. Sixty hundred Ross male broilers were used in a factorial arrangement 2×2+1 (two animal sources by-products – poultry viscera meal and bovine blood meal crude and ideal protein) and one basal diet (corn + soybean meal), envolving a total of five treatments with four replications of thirty broilers each. Weight […]

The coeficients of apparent digestibility of dry matter (ADDM), organic matter (ADOM), crude protein (ADCP), ether extract (ADEE), total carboidrates (ADTCHO), nonfiber carboidrates (ADNFC), neutral (ADNDF) and acid detergent fiber (ADADF), were determined to evaluate the effect of diferents inclusions of broiler litter (0, 10, 20 and 30% in dry matter basis), with 45% forage cactus associaded to sugar cane bagasse, urea and cottonsead meal, using the method of indigestible acid detergent fiber as intern indicator to estimate fecal dry […]

An experiment was carried out at to evaluate the fermentation pattern and chemical-bromatologycal composition of fresh and wilted Ipomoea glabra Choisy and Jaquemontia asarifolia L.B. Smith silages. To evaluate the fermentation pattern silos were open in 3, 7, 14, 21 e 28 days of fermentation. The used design was completely randomized in split-plot to the fermentation pattern; and factorial outline 2 X 2 with four reapplication to the chemical analysis. In the material before ensiling were determined pH values, NH3-N […]

The present study had the objective of identifying different management systems related to newborn dairy calves morbidity and mortality, with emphasis on colostrum feeding. It was used 211 herds in the South Center Region of Minas Gerais State, separated into three production categories: category A, from 200 to 600 L/day; category B, from 601 to 1000L/day; and category C, >1001 L/day. The dairy farmers were interviewed through a questionnaire that embraced the production aspects, herd management and newborn performance, focusing […]
