1. Energy utilization of light and heavy weaned piglets subjected to different dietary energy levels
ABSTRACT This study was conducted to evaluate the effects of dietary metabolisable energy (ME: 3.25, 3.40, 3.55, or 3.70 Mcal kg−1) and weaning weight (WW: light 4.0±0.7 kg, and heavy: 6.3±0.6 kg) on productive response and energy utilization of weaned piglets. Sixty-four male piglets were housed in 32 metabolic cages (two animals per cage) during the fi

2. Influência do peso dos leitões na uniformização no desempenho de primíparas suínas e suas leitegadas. / Influence of piglets weight at crossfostering on the performance of primiparous sows and their litters
The objective of this study was to evaluate the effect of crossfostering piglets with different birth weight on feed intake, body reserve losses and reproductive performance of primiparous sows and on performance of their litters until weaning. Primiparous sows were allocated in three groups: group A (n= 31) ¿ litters with 14 Light piglets (1.0-1.2 kg); gro

3. Efeito do peso ao nascer e do tamanho da leitegada ao nascimento no desempenho de fêmeas puras Landrace até a puberdade / Effectofbirth weightandlitter size of femalepurelandrace ontheir performanceuntil puberty
The aim of this study was to evaluate the effect of litter size in which gilts were born and of their individual birth weight on mortality and cullingof these gilts until the moment of selection and on occurrence of puberty. The study evaluated 1525 landrace gilts, identified and weighted until 18 hours after birth. The gilts were also weighed on weaning (n=

4. Alternativas de manejos em leitões neonatos para melhorar o desempenho na fase lactacional. / Alternatives of management to assist in the survival of neonatal pigs
As maiores perdas por mortalidade na maternidade concentram-se nos primeiros três dias de vida, ficando em torno de 30 a 40% para leitões que nascem abaixo de 1000g. O meio de obter um maior sucesso na diminuição da mortalidade neonatal tem sido através do intensivo manejo na maternidade como: indução e atendimento ao parto, equalização da leitegada

5. Procurement and Maintenance of Germ-Free Swine for Microbiological Investigations1
Germ-free swine were routinely procured by both hysterectomy and hysterotomy (Caesarian section). By means of light-weight portable equipment, piglets could be obtained and transported to the laboratory (without contamination) over distances in excess of 100 miles. The isolators employed in rearing were constructed of stainless steel and flexible plastic fil
