Abstract

Genetic improvement of swine enabled more prolific sows and has resulted in an increase of litter size at birth and piglets weaned per sow per year. This increased of litter size has added birth weight variation within litters and had reduced the vitality of newborn piglets. In this context, the use of feeding strategies, involving complex initial diets enriched with milk-products and animal plasma proteins has generally worked well to increased feed intake. The feeding liquid-diet to newborn piglets has showed contradictories results obtained by authors, but there were few results about labor to supply in the liquid-diets. Thus, this project aims to determine the efficiency of the supply of liquid-diet, automated mode, from 3 to 21 day old piglet on intestinal integrity, frequency of diarrhea, performance until slaughter and reflections in the sows. Eighteen females with litters ranging from 11 to 12 piglets will be used. The treatments will be provided for litter, divided into 3 groups: Control (CT) piglets receive only sow's milk; Diet Dry (DD) piglets receive sow's milk + diet dry; Liquid Diet (LD) piglets receive sow' milk + liquid diet. The DD will be provided directly at the feeder and LD will be provided for an outfit that will make the mixture in the ratio 2:1 ratio, water and food, prior to supply to piglets. The diet is based on pre-gelatinized rice, extruded soy and whey and is the same for both treatments; DD and LD. Performance from birth to slaughter, the intestinal morphology and the frequency of days with diarrhea in piglets and performance, plasma metabolite profile and weaning estrus interval n sows will be evaluated. In the statistical analysis, data on the frequency of diarrhea were transformed using the function arcsin and performance, intestinal morphology, plasma metabolic profile and weaning estrus interval will be subjected to analysis of variance (PROC MIXED), using the software SAS. Differences were considered significant when P < 0.05.
