| Numerous vertebrates, and in particular birds, ingest stones (geo-gastrolites) to favour the breakdown and digestion of food in the muscular stomachs. Between 1993 and 1994 we evaluated the quantity, relative abundance and quality of autochthonous (geo-gastrolites) and allochthonous (pieces of glass) components of the grit in gizzards of black-faced ibis (Theristicus melanopis) inhabiting the pastures of southern Chile. Grit elements were present in 32 out of 48 (66,7%) of all gizzard analysed. A total of 572 particles were recorded from which, 69.1% corresponded to autochthonous elements and 27.8% were allochthonous particles. Both components are similar in shape; however glass contributes considerably more in terms of mass. Gender differences reveal that... |

| Three 54ha "farmlets" were established in 2000 near Uralla, NSW to trial high input, moderate input and intensive rotational grazing systems. A representative farm approach was used to interpret the profitability results of the trial from July 2000 to June 2005 at a commercial scale level to make research results more relevant to farmers. At the gross margin level, the high input farmlet had the highest annual gross margins, but this farmlet had the worst whole farm performance. These contrasting results support the claim that annual activity gross margins cannot alone indicate the profitability of an investment. This demonstrates that whole farm analysis is the most suitable method to assess different grazing systems. |

| O estudo do comportamento materno-filial se torna importante por permitir classificar as ovelhas pela sua reatividade, resultando em maior sobrevivência dos cordeiros, o produto comercial da ovinocultura. Objetivou-se caracterizr as variáveis do comportamento materno de ovinos pantaneiros no período do periparto e correlacionar com as características produtivas. Foram utilizadas 27 ovelhas pantaneiras com idade média de 3,8 anos e peso corporal médio de 47 kg. As observações do comportamento ocorreram desde o início do parto até 2 horas após, quando foram registradas as seguintes observações: permanência da ovelha parturiente com o rebanho, grau de agitação durante o parto, postura corporal e tempos de latência do cordeiro para ficar em pé e para mamar.... |

| ABSTRACT: Plant growth regulators are an immense group of substances that have the ability to alter growth pattern of plants and can be used for improving plant growth and productivity. A study was conducted in the Xilin Gol grassland of Inner Mongolia, China, to ascertain the growth and biomass production of Stipa krylovii in response to exogenous application of different growth regulators at various concentrations viz. naphthalene acetic acid (NAA), 6-benzylaminopurine (6-BA), brassinosteroid (BR), sodium nitrophenolate (SNP) and forchlorfenuron, and gibberellic acid (GA3). Application of growth regulators significantly enhanced the growth and biomass production of S. krylovii. The height of vegetative shoot was enhanced mostly by the application of 100... |
