1. Milk fatty acid composition of unsupplemented dairy cows grazing on a tropical pasture
ABSTRACT This study aimed to evaluate the milk fatty acid (FA) composition of unsupplemented dairy cows grazing on elephantgrass (Pennisetum purpureum Schum. cv. Pioneiro) pastures under three grazing management strategies: pre-grazing height of 120 cm with defoliation intensities of 50 and 70% of the initial height (treatments 120/50 and 120/70) and pre-gra

2. Fatty acid profile in vertical strata of elephant grass subjected to intermittent stocking
ABSTRACT The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate climate grasses and the literature with tropical grasses

3. Herbage utilisation efficiency of continuously stocked marandu palisade grass subjected to nitrogen fertilisation
Nitrogen fertiliser accelerates plant growth and increases herbage utilisation efficiency in continuously stocked temperate grass swards, indicating greater herbage production and harvest efficiency. There is no similar evidence, however, for tropical pastures. In this study we evaluated the morphogenetic responses, the patterns of defoliation and the effici

4. Morphogenesis on age categories of tillers in marandu palisadegrass
Knowledge regarding morphogenetic characteristics has contributed to the understanding of plant responses to variations in climatic conditions and management practices. However, the original framework has been developed for temperate grass species, and indicates no ontogenetic effect on the expression of morphogenetic traits. Similar information for tropical

5. Influência de sistemas de rotação de sementes de gramíneas forrageiras temperadas na composição do banco de sementes invasoras no solo / Influence of temperate grass seed rotation systems on weed seed soil bank composition
Em consequência da mudança nas práticas agronômicas nos cultivos de gramíneas perenes para sementes no oeste de Oregon, EUA, sistemas alternativos de rotação estão sendo considerados com a finalidade de reduzir a infestação de plantas invasoras. De um modo geral, inexistem informações dos efeitos de práticas agronômicas alternativas e aplicaç�

6. NUTRITIVE VALUE OF DIETS BASED ON FRESH RYEGRASS (Lolium multiflorum, LAM.) FORAGE SUPPLEMENTED WITH NITROGEN OR ENERGY / VALOR ALIMENTAR DE DIETAS COM AZEVÉM (Lolium multiflorum, LAM.) E SUPLEMENTAÇÃO NITROGENADA OU ENERGÉTICA
The present study was carried out to determine the effects of supplementing fresh ryegrass forage based diets with starch, rumen degradable or undegradable protein sources on intake, digestion and nitrogen retention, rumen digestibility and the duodenal nitrogen flow. Ten Corriedale lambs (26 kg mean body weight), kept in metabolic cages were used in a 5 x 5

7. PERFIL DE ÁCIDOS GRAXOS, EMBUTIDO FERMENTADO E CARACTERÍSTICAS DA CARCAÇA DE OVELHAS DE DESCARTE / FATTY ACIDS PROFILE, FERMENTED SAUSAGE AND CARCASS TRAITS OF CULLING SHEEP
The experiment was accomplished with the objective of determine the differences in the carcasses traits and the fatty acids profile in meats of culling sheep of two genetic groups in two feeding systems and also to evaluate fermented sausage type salami produced with this meat. Were used 20 culling ewes, being 10 of the Ideal race and 10 of the Texel race, w

8. Antisense-mediated silencing of a gene encoding a major ryegrass pollen allergen
Type 1 allergic reactions, such as hay fever and allergic asthma, triggered by grass pollen allergens are a global health problem that affects ≈20% of the population in cool, temperate climates. Ryegrass is the dominant source of allergens because of its prodigious production of airborne pollen. Lol p 5 is the major allergenic protein of ryegrass pollen, j

9. Brachypodium distachyon. A New Model System for Functional Genomics in Grasses1
A new model for grass functional genomics is described based on Brachypodium distachyon, which in the evolution of the Pooideae diverged just prior to the clade of “core pooid” genera that contain the majority of important temperate cereals and forage grasses. Diploid ecotypes of B. distachyon (2n = 10) have five easily distinguishable chromosomes that d
