    The objective of this research was to evaluate the ingestive behavior and nutrient intake of Santa Inês crossbred lambs fed Tifton 85 hay supplemented with concentrate. Twenty lambs, not neutered, with an initial live weight of 20.3 ± 3.6 kg, in a completely randomized design, with five repetitions were used. Four treatments were studied constituted by Tifton 85 hay associated to four concentrate levels (0.0%; 0.66; 1.33 e 2.0% LW). The diets were provided ad libitum twice a day and the animals were submitted to observation by 24 hours integral periods, in ten-minute intervals, to assess behavioral activities. Dry matter intake (DMI) was estimated through the external indicator technique using the LIPE®. Was no effect of concentrate level on DMI and CPI, over the time spent feeding (TAL) and rumination (TRU), in min/day and min/kg of DM, NDF and CP, and time spent with leisure (TOC) in min/day. The feeding and rumination efficiencies in grams of DM and CP increased linearly with the increasing in the concentrate levels. Conversely, none of the regression models if adjusted to data the efficiency of feeding and rumination expressed in g NDF. In parallel, it was study a correlation between estimates of lambs intake by using external indicator LIPE® and the weight difference between food offered and remains of the diet by interpolations from the behavioral variable feeding time. It was observed a high association between the methodologies for estimating intake of DM and CP, which suggests its use to estimate the individual consumption of feedlot lambs

    Perfil protéico de vacas de grupos genéticos holandês X gir de segunda lactação

    The dairy farming is practiced throughout the national territory and approximately 70% of milk production in Brazil comes from crossbred animals derived from European dairy cattle breeds with zebu breeds of excellent adaptation to tropical conditions. Due the metabolic profile studies have focused on specialized pure breeds in this research was aimed to assess the metabolic profile of protein in two genetic groups of Holstein x Gir cows, from the second lactation order, in two periods of lactation, during the dry season. This work was carried out at the Fazenda Santa Luzia, belonging to the Grupo Cabo Verde, Passos - MG. Data were collected between May and August 2009, from ½ HG cows (37) and ¾ HG cows (35). Two periods of lactation were studied: from 28 to 60 and from 110 to 130 days. The feeding of the herd was conducted in accordance with milk production. From each animal, fasting, 10 mL of blood without anticoagulant, and 4.5 mL, with EDTA anticoagulant were collected. Milk yield and body condition score were evaluated and serum levels of urea, albumin, total protein and hemoglobin determined using a manual spectrophotometer, based on specific procedures for each component. Results showed that milk production was higher in animals ¾ HG in both periods of lactation and body condition score higher in the animals of the second period of lactation, but similar when comparing genetic groups. Although had occurred differences among lactation periods to the genetic groups for urea, albumin and total protein, results for these variables were similar as well as for hemoglobin into genetic groups. However genetic groups presented different results from those obtained for purebreds, demonstrating the need particularly to reconsider the nutritional management of these groups, when related to the purebreds. So, it s suggested that others research could be done in these conditions in order to elucidate this uncertain and to enable to construct tables with specific reference values for these genetic groups
