Agronomia e ecologia dos lameiros
Pires, Jaime; Fernández-Núñez, E.; Fernandes, Adelaide; Pires, João; Bernardo, Adelino; Galvão, Lurdes; Aguiar, Carlos; Moreira, NunoOs lameiros são tradicionalmente as pastagens de montanha em Portugal com maior importância para a produção animal, principalmente de bovinos. Estes agroecossistemas, apesar de serem uma componente fulcral para o funcionamento dos sistemas agro-pecuários de montanha, não têm sido objeto de estudo de forma continuada e sistemática.
Produção e valor nutritivo de pastagens de montanha
Pires, Jaime; Fernández Nuñez, E.; Fernandes, Adelaide; Pires, João; Bernardo, Adelino; Aguiar, Carlos; Galvão, Lurdes; Moreira, NunoOs lameiros são tradicionalmente as pastagens de montanha em Portugal com maior importância para a produção animal, principalmente de bovinos. Estes agroecossistemas são deste modo uma componente fulcral para o funcionamento dos sistemas agro-pecuários de montanha, além do seu efeito positivo em termos ambientais e paisagísticos. Contudo, o seu estudo não tem tido a relevância que este tipo de culturas merecem ...
Grazing regimes and fertilisation rates: effects on dry matter yields, crude pr...
Fernández-Núñez, E.; Pires, Jaime; Fernandes, Adelaide; Pires, João; Aguiar, Carlos; Galvão, Lurdes; Moreira, NunoThe aim of this study was to evaluate the effect of two grazing regimes: the usual for the area and late spring grazing, and three rates of N fertilisation, on dry-matter (DM) yields and nutritive value in three mountain meadows (Anthemido-Cynosuretum cristati, Gaudinio-Agrostietum cristati and Bromo-Cynosuretum cristati). The results showed that the lowest DM yield was obtained on Bromo-Cynosuretum cristati me...

Nutritive value of meadows in the Northeast of Portugal
Fernández-Núñez, E.; Pires, Jaime; Fernandes, Adelaide; Pires, João; Aguiar, Carlos; Galvão, Lurdes; Moreira, NunoMeadows continue to be the most important source of pasture and hay for beef cattle production in the hill and upland areas in the NE region of Portugal. The aim of this study was to evaluate CP contents and IVOMD values during the year, in three harvests (spring, hay cut and autumn) under the effect of three rates of N fertilisation in seven mountain meadows. The results showed that the highest CP and IVOMD oc...

Effects of PGF(2A) administration at the onset or the end of a short-term proge...
Correia, Teresa Montenegro; Azevedo, Jorge Manuel Teixeira de; Mendonça, Álvaro; Fontes, Paulo J.; Galvão, Lurdes; Cardoso, Manuel; Velasco, HelenaIn order to assess the reproductive effects of Prostaglandin F2alfa (PGF2alfa) administration at the onset or the end of a progestagen treatment in Portuguese Serrana goats, an initial group of 44 females (5 were later rejected for several reasons) aged between 3 and 7 years was used. In May (beginning of the breeding season), all goats were treated with an intravaginal sponge impregnated with 20 mg of fluoroge...

Valentim, Ramiro; Azevedo, Jorge Manuel Teixeira de; Mendonça, Álvaro; Fontes, Paulo J.; Galvão, Lurdes; Cardoso, Manuel; Velasco, HelenaIn order to assess the effects of a long-term progestagen treatment associated with different doses of eCG (equine Chorionic Gonadotropin) to advance the breeding season in Portuguese Churra Galega Bragançana ewes, an initial group of 41 females (2 were later rejected) aged between 2 and 7 years was used. In middle May, all ewes were treated with an intravaginal sponge impregnated with 20 mg of fluorogestone ac...

Correia, Teresa Montenegro; Azevedo, Jorge Manuel Teixeira de; Mendonça, Álvaro; Fontes, Paulo J.; Galvão, Lurdes; Cardoso, Manuel; Velasco, HelenaThe control of the reproduction activity plays an essential role in modern animal production systems allowing higher management flexibility and profitability. Short-term progestagens treatments are becoming increasingly popular. Nevertheless the best moment to administrate Prostaglandin F2a (PGF2a) is still in debate. The current study aims to assess the reproductive effects of PGF2a injected at the onset or th...
