Forty weanling Angus and Hereford calves averaging 159kg were assignedrandomly to 1) corn silage (CS). 2)Brandes sweet sorghum silage (BS). 3)Theis sweet sorghum silage (TS) or 4) fescue hay (FH) treatments. Animals were group-fed ad libitum their respective diets for 129 d. Intake of DM, CP and gross energy (GE), as well as feed conversion, was comparable among treatments (P < 0,5). Average daily gain (ADG) was greater (P < 0.5) for cattle fed BS and CS than for those fed TS or FH. Apparent digestibility of DM were not different (P > .05) among silages,whereas FH was lowest in DM digestibility. Organic matter digestibilities were greater (P < .05) for BS, followed by TS, CS and FH. Digestibilities of CP and ether extract (EE) were greater (P < .05) for steersfed BS and TS than for those fed CS diets. Gross energy digestibilities also were greater (P < .05) in BS-fed than in CS-fed animals. Steersfed silage diets had greater digestibilities of EE and GE than did those fed the FH diet. Steers fed the BS diet digested more (P < .05) NDF, ADF, hemicellulose and cellulose and cellulose than those fed TS or FH, but were equal (NDF and ADF) or superior (Hemicellulose and cellulose) to CS-fed steers in digestibilities of these cell wall constituents. More (P < .05) N was retained in sorghum silage groups than in CS or FH groups. Brandes sweet sorghum silage is a suitable substitute for CS for growing calves. |

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.
