Habilidade materna na composição de índices de seleção na pecuária de corte.
Provedor de dados: 14
Autores: CARNEIRO JUNIOR, J. M.
Na pecuária de corte, a criação de bezerros é a fase do processo de reprodução compreendida entre o nascimento e a apartação desses animais das matrizes. nessa etapa, é gerada a base que sustentará toda a cadeia de produção da carne bovina, ou seja, o bezerro desmamado. Entretanto, apesar de importante, por muitos anos essa etapa foi considerada a menos rentável do setor pecuário, geralmente desenvolvida por pequenos produtores e reservada aos piores pastos da propriedade.

Environmental and dam effects on cannibalism in Wistar rat litters
Provedor de dados: 3
Autores: Tarôco, Graziela; Gaya, Leila de Genova; Resende, Daniela Regina; Santos, Ivan Carlos dos; Madureira, Ana Paula.
The factors related to cannibalistic behavior of dams in a Wistar rat colony are identified and analyzed. The maternal genetic effects were tested as a random effect by the method of generalized linear models. The season at parturition, the dam´s age at parturition and the density of the room at parturition were tested as fixed effects, whereas the litter size at birth was tested as a co-variable. The genetic effect of the dam was significant for the number of cannibalized pups. Although the season at parturition, the dam´s age and room density on the day of parturition were not individually significant (p &gt; 0.05), most of the interactions between the variation sources were significant (p &lt; 0.05). Cannibalism occurred mostly in dams aged over 241...

Effect of 5-HT1B receptor agonists injected into the prefrontal cortex on maternal aggression in rats
Provedor de dados: 56
Autores: Veiga,C.P.; Miczek,K.A.; Lucion,A.B.; Almeida,R.M.M. de.
Serotonin (5-HT1B) receptors play an essential role in the inhibition of aggressive behavior in rodents. CP-94,253, a 5-HT1B receptor agonist, can reduce aggression in male mice when administered directly into the ventro-orbitofrontal (VO) prefrontal cortex (PFC). The objective of the current study was to assess the effects of two selective 5-HT1B receptor agonists (CP-94,253 and CP-93,129), microinjected into the VO PFC, on maternal aggressive behavior after social instigation in rats. CP-94,253 (0.56 µg/0.2 µL, N = 8, and 1.0 µg/0.2 µL, N = 8) or CP-93,129 (1.0 µg/0.2 µL, N = 9) was microinjected into the VO PFC of Wistar rats on the 9th day postpartum and 15 min thereafter the aggressive behavior by the resident female against a male intruder was...

The brain decade in debate: VIII. Peptide hormones and behavior: cholecystokinin and prolactin
Provedor de dados: 56
Autores: Beinfeld,M.C.; Bittencourt,J.C.; Bridges,R.S.; Faris,P.L.; Lucion,A.B.; Nasello,A.G.; Weller,A.; Felicio,L.F.
This article is a transcription of an electronic symposium held on November 28, 2000 in which active researchers were invited by the Brazilian Society of Neuroscience and Behavior (SBNeC) to discuss the advances of the last decade in the peptide field with particular focus on central actions of prolactin and cholecystokinin. The comments in this symposium reflect the diversity of prolactin and cholecystokinin research and demonstrate how the field has matured. Since both peptides play a role in reproductive behaviors, particularly mother-infant interactions, this was the starting point of the discussion. Recent findings on the role of the receptor subtypes as well as interaction with other peptides in this context were also discussed. Another issue...
