AMINO ACID ANALYSIS IN THE SHORE CRAB CARCINUS MAENAS (DECAPODA: BRACHYURA)
(2010)Although amino acid flux models have been developed in fish and other crustaceans, this is the first study to present an amino acid flux model for crabs. This study investigates the influence of different feeds and the ... -
Body fatness affects feed intake of sheep at a given body weight
(2006)In a 1-yr experiment, nutritional treatments were used to produce different combinations of BW and BCS in lambs. The experiment served to quantify the effects of BW and BCS on ADFI by sheep. Ewe lambs (n = 78) were assigned ... -
Consequences of protein supplementation for anorexia, expression of immunity and plasma leptin concentrations in parasitized ewes of two breeds
(2009)The periparturient relaxation of immunity (PPRI) against parasites in ewes has a nutritional basis. We investigated whether ewes experience a reduction in food intake (anorexia) during PPRI and if the magnitude of anorexia ... -
Feeding behavior during long-term hexarelin administration in young and old rats
(2008)Ghrelin, a 28-amino-acid peptide isolated from the stomach, is the natural ligand of the GH-secretagogues receptor-la (GHS-R1a) and, so far, the only discovered circulating appetite-stimulating hormone. Similarly to ghrelin, ... -
Human ghrelin decreases pituitary response to GnRH in superovulated ewes
(2013)In addition to its metabolic role, ghrelin has been found to suppress luteinizing hormone secretion in many species acting mainly at the hypothalamic level. The objectives of the present study were to test the hypothesis ... -
In silico exploration of the effects of host genotype and nutrition on the genetic parameters of lambs challenged with gastrointestinal parasites
(2007)An in silico mathematical model was used to explore the effect of, and the interaction between, (i) nutrition, (ii) genotype for growth and (iii) genotype for resistance, on the estimates of genetic parameters for resistance ... -
In silico exploration of the mechanisms that underlie parasite-induced anorexia in sheep
(2011)A model was used to investigate two mechanisms describing reductions in food intake (anorexia) observed during gastrointestinal parasitism in lambs, and to explore relationships between anorexia and food composition. The ... -
Leptin concentrations in the follicular phase of spontaneous cycles and cycles superovulated with follicle stimulating hormone
(1998)It has been reported that oestradiol may play a role in the production of leptin from adipocytes, To investigate this relationship further, nine normally ovulating women were studied during two menstrual cycles, i.e. an ... -
Leptin, Adiponectin, and Ghrelin Levels in Female Patients with Asthma during Stable and Exacerbation Periods
(2013)Objective. The mechanisms underlying the relationship between obesity and asthma have not been fully established. Data in the literature suggest that adipose tissue-derived hormones may be implicated. However, no definite ... -
A model for predicting feed intake of growing animals during exposure to pathogens
(2006)A general model is proposed for predicting the effects of subdinical pathogen challenges of different doses and virulence on the relative feed intake (RFI) of animals. The RFI is defined as the feed intake (FI, kg/d) of ... -
A model to account for the consequences of host nutrition on the outcome of gastrointestinal parasitism in sheep: model evaluation
(2007)This paper describes sensitivity analyses and expectations obtained from a mathematical model developed to account for the effects of host nutrition on the consequences of gastrointestinal parasitism in sheep. The scenarios ... -
A novel flexible method to split feeding behaviour into bouts
(2009)Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the ... -
The structure of feeding behavior in commercial broiler lines selected for different growth rates
(2009)Selection for increased growth rate in livestock is accompanied by increased requirements for food resources. It has been suggested that more intensively selected birds, such as broilers, have altered food intake control ...
