The aim of this study was to identify possible effects of different vaccination strategies (concomitantly or not) against brucellosis and clostridia on intake, performance, feeding behavior, blood parameters, and immune responses of dairy heifers calves. Fifty heifers calves were enrolled [38 Gyr (Zebu, Bos taurus indicus) and 12 5/8 Holstein × Gyr]. At 120 d of age, animals were randomly distributed among 3 groups: B (n = 18), vaccinated against brucellosis; C (n = 14), vaccinated against clostridia and CB (n = 18), vaccinated concomitantly for both. Rectal and thermographic temperatures were evaluated on days ?1, 0, 1, 2, 3, 5, 7,10, 14, and 28 relatives to the vaccination day. Feed and water intake, body weight (BW), and feeding behavior were monitored daily by an electronic feeding system. Blood was sampled on days 0, 3, 7, 14, and 28, relative to the vaccination day for determination of glucose and ? -hydroxybutyrate (BHBA) concentrations. Blood sampled on day 0 (prevaccination) and on days 28 and 42 were used to evaluate the immune response against Brucella abortus and clostridia. There was an increase in rectal temperature between the first and the third day postvaccination in the 3 groups. The thermography revealed an increase of local temperature for 7 d on groups B and CB. Group C had increased local temperature for a longer period, lasting for up to 14 d. Dry mater intake was reduced for groups B and CB, but no alteration was observed for group C. No alterations regarding initial BW, final BW, average daily weight gain, and feed efficiency were observed. No differences were observed for the 3 vaccination groups for blood parameters throughout the evaluation period. The concomitant vaccination against brucellosis and clostridia led to lower neutralizing antibody titers against epsilon toxin of Clostridium perfringens and botulinum toxin type C of C. botulinum (C > CB > B). When cellular proliferation assay and serological tests to B. abortus were evaluated, no differences were observed between groups B and CB. The present results indicate that the concomitant vaccination against brucellosis and clostridia has no relevant impact on the intake, performance, and feeding behavior of dairy calves. However, the concomitant vaccination of vaccines against these 2 pathogens impacts animal immunity against clostridial infections.

The inclusion of high doses of concentrate in the diet of cattle promotes changes in metabolic activity, as well as in the organs. However, this high activity can lead to hepatic alterations, due to the characteristic of an organ of high activity in nutrient metabolism. The aim of this study was to evaluate the influence of non-antibiotic additives to replace antibiotics in the diet of cattle raised on intensive pasture on liver parameters. The experiment was conducted at Embrapa Agrossilvipastoril, in Sinop - Mato Grosso. Forty cattle of the Nelore breed, uncastrated, with mean age of 22 ± 2 months and mean initial body weight of 415 ± 5 kg, were randomly divided into four treatments: supplement containing non-ionophore additive (0.07 g kg DM-1 of virginiamycin) (VM); supplement containing yeast-based probiotic (3 g per 100 kg body weight) to replace virginiamycin (ADV); supplement containing 1.4 g kg DM-1 of tannin to replace virginiamycin (TN1.4); supplement containing 2.1 g kg DM-1 of tannin to replace virginiamycin (TN2.1). Blood samples were collected via tail vein puncture at the adaptation and at the end of the experiment, and all animals were sampled. The samples were centrifuged, aiming the separation of serum, for the analysis of blood parameters. At the end of the experiment all animals were slaughtered, and the liver weights of each animal were recorded. The means of the treatments were analyzed via PROC MEANS of SAS and the means were compared using the Tukey test (α = 0.10). There was no difference between the additives for liver weight in kg (P = 0.373) and carcass percentage (P = 0.801). Lactate concentrations were not influenced by the additives (P = 0.419). Serum concentrations for glutamic-oxalacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) were higher in VM and TN 1.4 treatments (P < 0.10), with mean values of 52.0 U L-1 and 94.45 U L-1, respectively. The enzymes GOT and GPT are markers of liver injury and can be found in both the cytoplasm and mitochondria of liver cells, where concentrations above 130 U L-1 for GOT and above 118 U L-1 for GPT indicate changes in liver tissue. From the evaluation of hepatic metabolic parameters and liver evaluation, no evidence was found to show liver injury, with enzyme concentrations being below the upper limit of ideal. Based on the evaluation of liver parameters of animals receiving high levels of supplementation we can conclude that non-antibiotic additives can be added to the diet of intensively grazed cattle, replacing virginiamycin.
