Performance and carcass characteristics of Santa Inês pure lambs and crosses with Dorper e Texel at different management systems R. Bras. Zootec.
Garcia,Iraides Ferreira Furusho; Costa,Tharcilla Isabella Rodrigues; Almeida,Amélia Katiane de; Pereira,Idalmo Garcia; Alvarenga,Flávio Augusto Pereira; Lima,Natália Ludmila Lins.
It was evaluated the performance and the carcass characteristics of 36 non-castrated male lambs, Santa Inês purebreed and crossbreeds from Dorper × Santa Inês and Texel × Santa Inês, managed in three different systems (intensive, semi-intensive and extensive), slaughtered at 38.41 ± 1.24 kg. It was observed the highest weight gain for lambs reared in intensive system, which also showed the greatest carcass yield. The management systems did not influence carcass measures of animals in intensive system much because of the greater weight of the carcass. The intensive system provided the best performance, regardless the genetic group. The use of Texel and Dorper breeds in crossings with Santa Inês increases carcass yield.

Physiological quality of dual-purpose wheat seeds from plants subjected to artificial defoliation Ciência Rural
Rodolfo,Giselle Regina; Souza,Clovis Arruda; Coelho,Cileide Maria Medeiros; Belizario,Karla Katy.
ABSTRACT: Defoliation may play a role in source-sink relationships and reduce the physiological quality of seeds. The main goal of this research was to investigate the effect of successive defoliations on physiological quality of wheat seeds in 'BRS Umbu' and 'BRS Tarumã' cultivars. Two experiments were carried out using a complete randomized design with four replications. Treatments included plants without defoliation (0), and those where 1, 2, and 3 consecutives defoliations were applied. Seeds from each treatment originated from four different lots. Data were analyzed with one-way analysis of variance and means compared by Tukey test at 5% statistical probability. Germination was not affected by defoliation, or the number of cuts, but an effect on vigor...
