Dietary Protein-Lysine-Energy Requirements and Relationships for Weanling Pigs and Dietary Lysine Requirements for Finishing Pigs (Amino Acids, Calories)
… the pig industry, however, specific quantative requirements of the early weaned pig for several nutrients have not been precisely identified, in particular, optimum dietary levels of protein, lysine, energy and their relationships. Also, the suggested dietary requirements vary greatly. …

Annual forage cropping-systems for midwestern ruminant livestock production
… to be broken into groups based on livestock dietary requirements and production goals. The second research trial focused on characterizing the forage quality and nutrient removal capabilities of amaranth as compared to other annual forage crops in the presence or absence of manure …

Folate status and milk folate concentration in lactating women
… to examine the relationship among folate intake, dietary iron, folate status, iron status and milk folate. Seven-day dietary records, milk samples, and blood samples were collected monthly for four months from five lactating women. Dietary iron and folate was analyzed. Milk folate, serum ferritin, …

The effect of dietary caloric restriction during pregnancy on maternal and fetal body composition in the obese Sprague Dawley rat
… assigned, on a weight basis, to one of three dietary treatments: ad lib, 15% caloric restriction, and 30% caloric restriction. All other nutrients were fed at levels to meet dietary requirements. Each treatment groups was further sub-divided into pregnant and non-pregnant animals. Rats were …

The effect of severe dietary caloric restriction during pregnancy on maternal and fetal body composition in the obese Sprague Dawley rat
… assigned, on a weight basis, to one of three dietary treatments: ad libitum, 30% caloric restriction, and 50% caloric restriction. All other nutrients were fed at levels to meet dietary requirements. Each treatment group was further divided into pregnant and nonpregnant subgroups. The …

Influence of Acremonium coenophialum on Festuca arundinacea growth, chemical composition, digestibility and tall fescue toxicosis
… and Zn in bloom-cut tall fescue hay were below dietary requirements for 227-kg steers. A disc meter was also evaluated for use in predicting yield of tall fescue. The meter is useful for non-destructive estimation of yield. Three feeding studies were conducted with steers (6/treatment/year). …

Vitamin D and health during pregnancy
… to address the question of whether nutritional requirements for vitamin D during pregnancy differ from non-pregnant adults, and to supply data of sufficient quality to inform such dietary reference values (DRVs) for vitamin D in pregnancy, if required. Using the dose-response relation of total …

Investigating the impacts of donkeys on a communal range in Namaqualand: how much does a donkey "cost" in goat units?
… is discussed in the light of the degree of dietary and habitat overlap, which were obtained from field observations. Habitat use was scored using dung frequency transects, and feeding was directly observed. It was found that in the wet season, one donkey eats as much as 5 / 7.6 goats (donkey …

Uncovering the genetic basis of seed amino acid composition in arabidopsis using a multi-omics integrative approach
… of major crops are not sufficient to meet dietary requirements. Protein in the seed is comprised of free amino acids (FAA) and protein bound amino acids (PBAA) which have both been the targets of manipulation in order to create a seed with a more balanced amino acid profile. However, upon …

Too hot to handle: how Martial Eagles (Polemaetus bellicosus) manage the heat in the Kruger National Park, South Africa
… temperatures. These results indicate that the dietary requirements of Martial Eagle may be potentially buffered from the effects of climate change through their ability to provision a wide diversity of prey. These differences are most likely due to these prey types having differing …

Trophic role of small cetaceans and seals in Irish waters
… inter alia, an understanding of their diet and dietary requirements. In this thesis, the foraging ecology of seven marine mammal species that regularly occur in Irish waters was investigated by reconstructing diet using hard parts from digestive tracts and scats. Of the species examined, two …

Soil properties, lime and phosphorus fertiliser management affecting grass production in Ireland
… and herbage P concentration for animal dietary requirements. However phosphorus is a finite resource and efforts must be made to reduce P needs in grassland to prolong its remaining lifespan. In Ireland current P fertiliser recommendations do not account for soil type differences, but …
