O objetivo deste trabalho foi avaliar o efeito da utilização de óleo de linhaça, em substituição ao óleo de soja, sobre a produtividade e a qualidade da carne de frangos de corte de ambos os sexos. Foram utilizadas 320 aves, em um arranjo fatorial 4x2 - quatro combinações dos períodos de fornecimento de óleo de soja e óleo de linhaça e dois sexos - e quatro repetições. O desempenho produtivo foi avaliado por pesagens da ração e das aves com 1, 21, 42 dias e no momento do abate, aos 49 dias de idade. Após o abate, foi avaliado o rendimento de carcaça e sua composição: cortes, vísceras e gordura abdominal. Foram determinados os teores de lipídeos totais, umidade e colesterol da carne. A dieta contendo óleo de linhaça melhorou a qualidade nutricional da fração lipídica da carne de frango, mas prejudicou o desempenho produtivo das aves.

Pigeonpea protein concentrate was prepared from full-fat decorticated raw flour. The water holding capacity of pigeonpea flour of decorticated seeds is 75% and its oil absorption capacity a 30%. The water holding capacity of the protein concentrate is three times the dry weight. The oil absorption capacity of the concentrate was 1,29 mL oil/g protein. The whipping capacity of the pigeonpea flour and its protein concentrate were evaluated.

In this work we used leaves of four species of Eucalyptus - E. bicostata Maiden, E. deanei Maiden, E. dunnii Maiden and E. viminalis Labill, grown in Colombo, Parana State, Brazil. Preliminary studies were done, in the following sequence: botanic identification, olfactory research, extraction and purification of the essential oil of each species. The physical and chemical tests done were the following: relative density, refractive index, optical rotation, solubility, coagulation point and cineol percentage. The essential oils analysed through gaseous chromatography, presented the following cineol percentage: E. bicostata Maiden - 26.92%, E. deanei Maiden - 70.21%, E. dunnii Maiden - 53.16% and E. viminalis Labill - 23.05%.

The aim of this research was to evaluate the intake and apparent digestibility of nutrients in sheep fed with diets containing different amounts of linseed meal. The treatments evaluated were: corn silage exclusive (control); corn silage + concentrate; corn silage + concentrate + 5% of linseed meal; corn silage + concentrate + 10% of linseed meal. The dry matter (DM) intake has increased in diets containing concentrated if compared to diet exclusively with corn silage (P<0.05), however, there was no effect of the inclusion of linseed meal in diets (0; 5 and 10%). As it was expected, the diets containing 5 and 10% of linseed meal resulted in an increase of ether extract (EE) intake. A higher apparent digestibility of DM, organic matter (OM) and neutral detergent fiber (NDF) in the animals fed with diets containing the concentrate was observed, independently of linseed meal proportion. According to the experimental conditions under which the experiment was developed, itis recommended to provide the diets containing until 5% of linseed meal, because there is no negative effect on dry matter and nutrients intake, as well as on apparent digestibility.

The objective of this study was to evaluate the supplementation of linseed as an omega-3 fatty acid supplier on the functional capacity of jumping horses. 6 horses disposed in two 3 x 3 balanced Latin squares were used. The treatments consisted of increasing levels of linseed mixed with flour and linseed oil in a ratio of 75:25, respectively, resulting in 0g (control), 60g and 120g on a daily basis per horse. The horses were supplemented for 30 days. Physical activity was jumping at riding class level. The functional parameters measured were lameness index, stride length and joint metacarpophalangeal (MCP) biometry (circumference and flexion angle). A significant linseed supplementation effect for doses of 60 and 120g was observed on the lameness index. Feeding 120g of linseed increased stride length while trotting (P<0.05). An increment of 0.5cm on MCP circumference was found in horses that received the control diet when compared to those horses that consumed 120g of linseed. Thus, supplementation of jumping horses with 120g/day of linseed promoted greater stride length at a trot and reduced swelling in the metacarpophalangeal joint, improving their functional capabilities.
