In female pigs feeding level has important effects on reproductive performance. This review is focused on the follicular development after low and high feeding levels during the luteal phase in gilts. Although aspects of diet composition seem to have a role in regulating reproductive performance, the most important aspect appears to be the plane of nutrition. Similar effects are described durin...

This study evaluated the influence of the initial weight, feeding period and temperature on weight gain and biological parameters of the non-parasitic phase of partially engorged Rhipicephalus sanguineus females that were artificially fed using plastic tips as feeding devices. The device did not alter the oviposition of the females or any other parameters evaluated. Furthermore, it was observed...

The main objective of this review is to discuss human feeding behavior based on evolution. With regard to feeding, the human species has undergone various changes during its evolutionary and social history, from the hunting and gathering phase, including the discovery of fire, to modern times, mainly after the implementation of agriculture. These changes exerted a direct influence on feeding ha...

In individual, single-phase feeding animals were fed extensively (group E--7 animals) or intensively (group I--7 animals) in semi ad libitum system. The mixtures differed in composition as well as energy and nutritional value, with constant ratio of protein to energy of 13.12:1 in intensive feeding and 13.04:1 in extensive feeding. Fibre content per 1 kg mixture was 3.43% in group I and 12.3% i...

Feeding under constant cold conditions resulted in a marginal shortening of feeding period and a major shortening of the subsequent developmental phase of all stages of Ixodes rubicundus Neumann 1904, the Karoo paralysis tick. Paralysis occurred in laboratory rabbits when nymphae were fed on them under constant warm, constant cold and fluctuating ambient winter conditions. This paralysis was fo...

This study provides the first data on muscle activity patterns during active feeding in a larval anuran. Data regarding muscle function during gill irrigation and hyperexpiration are also provided. Electromyographic and kinematic data were recorded from six mandibular and hyoid muscles in unanesthetized, unrestrained larvae of Rana catesbeiana. Only three (hyoangularis, orbitohyoideus, anterior...

Providing rats and mice with access to palatable high fat diets for a short period each day induces the consumption of substantial binge-like meals. Temporal food intake structure (assessed using the TSE PhenoMaster/LabMaster system) and metabolic outcomes (oral glucose tolerance tests [oGTTs], and dark phase glucose and insulin profiles) were examined in Sprague-Dawley rats given access to 60%...

26 The orexins (Orexin-A and orexin-B) are neuropeptides which are secreted from 27 neurons in the lateral hypothalamus, which participate in the regulation of feeding 28 behavior. It remains to be determined, however, how the orexins exert their effects on 29 feeding behavior, including masticatory movements. To this end, we analyzed food 30 intake behavior and masticatory muscle activity usin...

according to high costs of phase shifters in antenna arrays, new methods for beam steering without phase shifter were introduced. frequency diverse array (fda) concept is another approach to beam steering problem. in this structure, the subsequent antenna elements are fed with stepped discrete frequencies causing continuous scanning of space in time. so a range-angle dependent scanning is made ...
