Hormones and feed intake [PDF]
Proceedings of the Nutrition Society, 1983 During the several decades that hormones have been considered for roles in the control of feeding, certain ones have gained special attention, although the role assigned to any one hormone has varied from time to time. Three classes of hormones have been considered in this review: gastrointestinal, brain, and pancreatic.

Methods in cattle physiology and behaviour – Recommendations from the SmartCow consortium., 2020 Knowledge about dry matter intake (DMI) is a very important element in cattle management. Modern, high producing dairy cows require great amount of feed in order to meet the nutrient and energy requirements for maintenance and milk production, particularly during early lactation.

What are the limits to feed intake of broilers on bulky feeds?
Poultry Science, 2021 The view that genetic selection for carcass yield has limited the size of the gastrointestinal tract (GIT) of modern broilers has sparked concerns that their capacity to cope with energy dilution or bulk is also limited. We investigated the capacity of male Ross 308 broilers to deal with increasing levels of bulk and aimed to identify a feed bulk ...

Effects of organic plant oils and role of oxidation on nutrient utilization in juvenile rainbow trout (Oncorhynchus mykiss) [PDF]
, 2012 The study compared the effect of four either fresh or force oxidized organic plant oils in diets for juvenile rainbow trout (Oncorhynchus mykiss) in which 47% of conventional LT fish meal protein was substituted by a mixture of 3 organic plant protein ...

Effect of pre-weaning solid feed and milk intake on caecal content characteristics and performance of rabbits around weaning [PDF]
, 2002 The aim of this study is to know the effect of different solid feed and milk intake during suckling on performance around weaning and on caecal content characteristics at weaning. In order to obtain different intakes of milk and solid feed, 13 litters of

Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle [PDF]
BMC Genetics, 2014 Feed intake plays an important economic role in beef cattle, and is related with feed efficiency, weight gain and carcass traits. However, the phenotypes collected for dry matter intake and feed efficiency are scarce when compared with other measures such as weight gain and carcass traits.

Feeding behaviour, swimming activity and boldness explain variation in feed intake and growth of sole (Solea solea) reared in captivity. [PDF]
PLoS ONE, 2011 The major economic constraint for culturing sole (Solea solea) is its slow and variable growth. The objective was to study the relationship between feed intake/efficiency, growth, and (non-) feeding behaviour of sole.

Residual feed intake in beef cattle [PDF]
Revista Brasileira de Zootecnia, 2008 Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth.
