The objective of this study was to evaluate the influence of feeding energy levels during the last third of gestation and lactation on performance of ewes and lambs up to weaning. The experiment was carried out in the sheep raising sector of Universidade Estadual de Londrina (UEL), from August to December of 2007. Thirty-two adult lambs with 105 days of gestation, average live weight of 57.55 kg and average body condition scores of 3.42 were used in the beginning of the experiment. The animals were confined in collective pens, distributed randomly in three treatments: 2.4; 2.2 and 2.0 Mcal of metabolizable energy (ME)/kg of dry matter (DM). Feed supply was ad libitum during the last third of gestation and lactation. Weaning occurred at 70 days. Body...

The objective of this study was to evaluate the characteristics of wool produced by ewes of different genetic groups, ages, and reproductive statuses. A total of 115 ewes, of the following genetic groups, were used: 10 Corriedale, 37 Hampshire Down, 26 1/2 Hampshire Down + 1/2 Corriedale, 24 1/2 Ile de France + 1/2 Corriedale, and 18 1/2 Suffolk + 1/2 Corriedale. Age was determined by the number of permanent incisors, ranging from four teeth to eight teeth. Ewes were further classified by their reproductive status into: lambed, having reared one lamb; and not-lambed. Hampshire and half-blood Suffolk ewes were heavier (53.2 and 52.7 kg, respectively), while Corriedale animals were lighter (40.1 kg). Older ewes and not-lambed ewes were heavier as well....

Influence of environmental factors on ponderal performance and morphometric characteristics of lambs of different genetic groups from birth to weaning
Provedor de dados: Revista Brasileira de Zootecnia

The objectives of this work were to evaluate the environmental effects (age of dam, type of birth and sex of lamb) and genetic groups (Hampshire Down and Ile de France, ½ and ¾ Hampshire Down, Ile de France and Suffolk, and ½ Texel) on performance and morphometric characteristics (height, length and heart girth) of lambs; to test regressions to predict live weight of lambs from body measurements; and to describe the growth type of the measurements as function of the weight. Weights and measurements were collected from birth to weaning, every 14 days. For evaluations of performance in relation to environmental effects and genetic groups, only data from birth and from weaning were used; for type of growth all collected data were used. Lambs from younger ewes...

Performance, carcass and meat quality of ewes supplemented with magnesium oxide
Provedor de dados: Revista Brasileira de Zootecnia
Autores: Constantino,Camila; Ribeiro,Edson Luis de Azambuja; Bridi,Ana Maria; Tarsitano,Marina Avena; Castro,Filipe Alexandre Boscaro de; Fernandes Júnior,Francisco; Mizubuti,Ivone Yurika; Pereira,Elzânia Sales.
The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus...

Autores: Ribeiro,Edson Luis de Azambuja; Oliveira,Humberto Cardoso; Castro,Filipe Alexandre Boscaro de; Mizubuti,Ivone Yurika; Silva,Leandro das Dores Ferreira da; Barbosa,Marco Aurélio Alves de Freitas.
Este trabalho teve como objetivo avaliar o desempenho em confinamento e a produção de carcaça e de componentes não carcaça de cordeiros dos grupos genéticos Texel x Hampshire Down (THD), Texel x Ile de France (TIF) e Texel x Suffolk (TS). Foram utilizados 17 cordeiros castrados, sendo seis THD, seis TIF e cinco TS, com idade de 120 dias e peso vivo médio inicial de 31,0±3,2kg. Os cordeiros foram confinados por um período de 51 dias, quando receberam diariamente ração concentrada comercial com 18% PB e 74% NDT, na proporção de 1,5% do peso vivo, mais cana-de-açúcar picada in natura à vontade. Não houve diferenças significativas (P&gt;0,05) para ganho de peso, peso final e escores de condição corporal entre os grupos genéticos; porém, cordeiros TS tiveram...
