Conference Theme

In March 1997 an international conference was held in Boston, Massachusetts, on the ways that the nutritional value and quality of foods are affected by how they are produced. It was organized by the School of Nutrition Science and Policy, Tufts University, and was attended by people from 19 countries.The conference theme was interpreted broadly, with “quality” encompassing not only biological and chemical characteristics such as nutrient content, but also social and political consequences of different production systems. In all, 46 papers were presented, the abstracts of which are printed here, followed by the closing address. The 20 papers marked with * are included in the proceedings volume.

ABSTRACT Diet, energy density (ED) and relative condition factor (Kn ) were used to investigate the energetic assimilation of the invasive fish Hemiodus orthonops under different environmental condition of the upper rio Paraná floodplain. Samples were taken in June and September 2013 and 2014. Nutrient content was determined for sediment. The diet was combined in the Food Index (IAi%), ED was expressed in Kcal/g of dry weight and Kn was calculated by: Kn = Wt/We, where Wt is the total weight and We the expected weight. Detritus/sediment prevailed in the stomachs of specimens from Ivinhema and Baia, while Algae was the main item in Paraná, reflecting the resource availability. ED and Kn from Ivinhema specimens were the greatest, consequence of the quality of food and lower spent on searching and handling food. The Paraná specimens showed lower ED values, but higher Kn values, due to algae consumption, a nutrient-rich resource. Baia presented high aluminum concentration on the sediment and the lower pH values, which contribute to reduce the nutritional value of the detritus and the ED and Kn values of their specimens. In conclusion, H.orthonops is capable to take advantage of the resources availability in the different environments, ensuring their establishment.

The article presents experimental material on changing the quality of a bean-silage with the introduction of the Biocomplex-BTU. The influence exerted by silos harvested on its basis on the productivity of dairy herds of large horned animals was revealed. A change in the nutrient content when using this biocomplex has been established.

Increasing the number of individual deer in captivity indicates an increase in the deer population. One of the factors affecting the increase in the deer population is a drop in the quality of feed and nutritional value adequate for deer. Therefore it is necessary to investigate the type of feed and feed nutrient content in captive deer drop in PT Gunung Madu Plantations (GMP). Nutrient content of feed drop in deer obtained through the proximate analysis by taking a sample of 100 grams per sample feed. This type of feed given drop in manager consists of the main feed forage consisting of grass and leaves, in the form of rice bran concentrate feed, and feed the tubers were given every month. Based on proximate analysis that has been made known that the feed drop-in provided by the organizer captivity contains good nutrition, as seen in the high water content, extract ingredients without nitrogen (BETN) high, protein and fibers that do not differ greatly in value and fat content is not excessive. Keywords: Drop in Feed Nutrition, Feeding Deer, Captive Deer PT.

As part of the search for sustainability in production systems, systems of annual crops intercropped with tropical forage plants have recently been used for silage production. Therefore, in the present study we aimed to evaluate the dry matter yield, fermentative parameters and nutritional value of the silage of sorghum intercropped with Paiaguas palisadegrass in different forage systems and maturity stages in a crop-livestock integration system. The experiment was conducted at the Goiano Federal Institute (Instituto Federal Goiano), Rio Verde Campus, Goiás, Brazil, in a completely randomised design with four replications in a 5 × 3 factorial arrangement with five forage systems (monocropped sorghum, monocropped Paiaguas palisadegrass, sorghum row intercropped with Paiaguas palisadegrass, sorghum inter-row intercropped with Paiaguas palisadegrass and sorghum oversown and intercropped with Paiaguas palisadegrass) and three maturity stages of the sorghum (milky, soft dough and hard dough). The results show that for all sowing methods, the silages of the intercropping systems harvested in the hard-dough stage provide a higher yield per area than did the monocropped sorghum and Paiaguas palisadegrass. The intercropping of sorghum with Paiaguas palisadegrass in crop-livestock integration systems could become an important option for the production of silage because intercropping minimises the inconveniences resulting from the fermentation process of the silage of monocropped grasses and improves the quality of the silage. These findings show this intercropping method to be advantageous strategy for the production of supplemental roughage in addition to contributing to the formation of pasture after the crops have been harvested for ensiling.

Legumes, such as red and white clover, are potentially important constituents of low input, environmentally friendly beef production systems. However, the effects of grazing clover on the quality of beef have not been assessed fully. Important aspects of meat quality are shelf-life (colour and lipid stability), flavour and human nutritional value, all of which are affected by components of the animals diet such as antioxidants and fatty acids. Tissues from lamb finished on swards containing white clover were reported to contain more linoleic and a-linolenic acid and less eicosapentaenoic acid (EPA, 20:5 n-3) (Vipond et al., 1993) compared to animals grazing grass. The objective of this study was to determine the quality of meat from two beef breeds raised on grass or grass plus white or red clover.
