Caprine lentivirus in sheep milk and semen. Repositório Alice
LIMA, C. C. V.; AYRES, M. C. C.; PINHEIRO, R. R.; COSTA, J. N.; ANDRIOLI , A.; SOUZA, T. S.; AZEVEDO, D. A. A.; SANTOS, V. W. S.; ARAÚJO, J. F.; SOUSA, A. L. M.; PEIXOTO, R. M.; DAMASCENO, E. M.; COSTA NETO, A. O..
Abstract: With the objective of detecting the presence of caprine lentivirus (CLV) in ewe milk and in ram semen, ten matrixes and four reproducers experimentally infected with CLV were used. Samples of ewe milk were collected during the four months of lactation, five collections per animal, totaling 50 samples. Regarding the rams, eight semen collections were made per animal, during one year of experimentation, totaling 32 samples. The milk and semen samples were submitted to DNA extraction and the nested polymerase chain reaction test (nPCR) to detect CLV proviral DNA. Eight (16%) of the milk samples were positive in nPCR originating from two ewes. Only one (3.12%) semen sample was positive. The amplification products were sequenced, and were confirmed to...

Effects of ammoniated pearl millet silage on intake, feeding behavior, and blood metabolites in feedlot lambs. Repositório Alice
RODRIGUES, T. C. G. de C.; FREITAS, P. M.; SANTOS, E. M.; ARAUJO, G. G. L. de; PIRES, A. J. V.; AYRES, M. C. C.; CARVALHO, L. M. de; SOUZA, J. G.; CARVALHO, G. G. P. de.
The aim of this study was to evaluate the effects of urea as an additive in the ensiling of pearl millet on the intake, feeding behavior, and metabolic parameters of feedlot-finished lambs. Thirty-two uncastrated, mixed-breed male lambs were used in the experiment. Diets were composed of pearl millet silage enriched with 0, 2, 4, or 6% urea plus a concentrate containing ground corn, soybean meal, and a mineral mixture. The treatments did not affect feed intake (P > 0.05) but influenced (P < 0.05) eating time (in min/day, in min/kg of dry matter (DM), and in min/kg of neutral detergent fiber (NDF)) and chewing time in min/kg of DM. Eating efficiency (in gDM/h and in g NDFap/h) responded linearly (P < 0.05) to the increasing urea levels in the...

Soroepidemiologia do lentivirus em ovinos no Semiárido baiano. Repositório Alice

[Epidemiology of small ruminant lentiviruses in sheep semiarid of Bahia]. Abstract: To verify the occurrence of antibodies against SRLV in sheep flocks from farms located in Microregion of Feira de Santana, Bahia, we performed a seroepidemiological survey of 10 municipalities with the most effective micro sheep: Antonio Cardoso, Feira de Santana, Ipecaetá , Ipirá, Itatim, Pintadas, Rafael Jambeiro, Santa Terezinha, Santo Estevão e Serra Preta, totaling 384 samples collected from 48 municipalities visited properties. The samples were subjected to the test of agar gel immunodiffusion (AGID) to give negative results in all sera investigated. This finding can be attributed to the composition of herds, which are mostly of animals breed, the system of creation...

Transmission of caprine arthritis encephalitis virus between sheep. Repositório Alice
LIMA, C. C. V. de; AYRES, M. C. C.; PINHEIRO, R. R.; COSTA, N. C.; SOUZA, T. S. de; ANDRIOLI, A.; AZEVEDO, D. A. A.; SANTOS, V. W. S. dos.
Abstract: This study was conducted to evaluate caprine arthritis encephalitis virus (CAEV) transmission among sheep using 15 lambs that were distributed in 2 experimental groups. The exposed group consisted of 10 lambs that remained with their mothers, who were experimentally infected with CAEV. The non-exposed group was characterized as the control group and was comprised of 5 lambs that remained with their CAEV-negative mothers. Blood samples were collected monthly from birth until 1 year of life. To evaluate the transmission, an agar gel immunodiffusion test (AGID), enzyme immunoassay (ELISA), immunoblotting (IB), and nested polymerase chain reaction (nPCR) techniques were used. The non-exposed group was negative in all of the tests throughout the whole...
