Voluntary food intake and reproduction
The underlying assumption I will make is that voluntary food intake is normally controlled so as to meet the requirements of the animal, especially for energy. This control is achieved by positive and negative feedbacks involving many pathways, in particular visceral receptors in communication with the central nervous system. Reproductive processes do not, on the whole, interfere seriously with...

متن کاملPreliminary study: voluntary food intake in dogs during tryptophan supplementation.
Tryptophan, a precursor of important molecules such as serotonin, melatonin and niacin, is an essential amino acid for dogs. In pigs, tryptophan supplementation has been shown to induce a significant increase in food intake. The aim of the present study was to assess whether long-term tryptophan supplementation increases voluntary food intake in dogs and to observe whether this was accompanied ...

متن کاملEquids
Alongside domestic horses and donkeys, the horse family, also known as equids, comprises six extant wild species of asses and zebras (Figure 1). Equids are extremely well represented in the fossil record, comprising a 55 million-year evolutionary history, punctuated by many episodes of innovation, extinction and migration. Limited to the single genus Equus today, in the Miocene (23.0–5.3 millio...
