1. Impact of birth weight and daily weight gain during suckling on the weight gain of weaning piglets
RESUMO Objetivou-se avaliar o efeito do peso dos leitões ao nascimento e do seu ganho de peso na maternidade sobre seu desempenho na fase de creche (21-61 dias de idade). Quinhentos e trinta e quatro leitões, provenientes de 55 primíparas, foram pesados ao nascimento, no desmame e na saída da creche. Os animais foram distribuídos em um delineamento inte

2. Developments of reproductive management and biotechnology in the pig
Abstract This review aims to describe changes in production environment, management tools and technology to alleviate problems seen with the present hyperprolific sow model. Successful parturition in the pig includes the possibility to express adequate maternal behaviour, rapid expulsion of piglets, complete expulsion of placenta, elimination of uterine cont

3. Arginine improves nutritional quality of sow milk and piglet performance
ABSTRACT The objective of this study was to evaluate the effect of L-arginine supplementation in lactation diets on the productive and reproductive performance of pluriparous sows and their litters. Seventy-six sows of the same genetic line were assigned to four treatments in a completely randomized design with 19 replicates. The experimental unit was the so

4. Timing carbon turnover (δ13C) in weaned piglet’s brain by IRMS
Abstract Isotope-ratio mass spectrometry (IRMS) is a potential tool that provides time-integrated estimate of assimilated and not just ingested nutrients. This feature turned possible its application to evaluate the effects of dietary nucleotides and glutamate on carbon turnover (δ13C) in the brain of weanling piglets. Eighty-seven piglets weaned at 21-day-

5. Impact of piglet birthweight and sow parity on mortality rates, growth performance, and carcass traits in pigs
ABSTRACT A total of 5502 piglets from 435 sows were selected for evaluation of the effect of piglet birthweight and sow parity on mortality rate (MR), growth performance, and carcass traits in pigs. Piglets were distributed into one of eight categories according to their weight (<600, 601-800, 801-1000, 1001-1200, 1201-1400, 1401-1600, 1601-1800, and >1801 g

6. Substitution of blood plasma with soy protein concentrate in piglet diet
ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight

7. The effect of supplementing sow and piglet diets with different forms of iron
ABSTRACT The objective of this study was to evaluate the effect of chelated iron supplementation on gestating and lactating sows and on their suckling and weaned piglets. Reproductive traits, piglet performance, hematological parameters, and the iron concentrations in colostrum, milk, and stillborn livers were measured. Ninety-six sows were subjected to one

8. Effects of dietary valine:lysine ratios on lactation performance of primiparous sows nursing large litters
ABSTRACT Eighteen sows were used to determine the effect of dietary valine:lysine (val:lys) ratios on lactation performance in primiparous sows and litter performance. Sows, raised in individual pens, were randomly assigned to 1 of 2 experimental diets containing different standardized ileal digestibility (SID) val:lys ratios of 0.80 or 0.85. Corn-soybean-wh

9. Effects of dietary mineral bioplex in pregnant and lactating sow diets on piglet performance and physiological characteristics
A total of thirty-six Landrace × Large White sows were inseminated with semen of Large White boars and studied in late pregnancy (30 days pre-partum) and lactation phases to determine the effects of trace mineral supplementation in organic (bioplex) and inorganic forms at two levels of supplementation (1 and 2 kg/t) on the reproductive performance of the fe

10. Efeito de altos niveis de zinco suplementar no desempenho e na mortalidade de leitoes.
Avaliou-se a suplementacao com Zn proveniente do oxido de zinco, na dieta de desmame de leitoes. Foram utilizados dois niveis de Zn (0 e 3.000 ppm) de 0 a 21 dias apos o desmame (primeira fase), tres niveis (0,1500 e 3.000 ppm) de 22 a 42 dias apos o desmame (segunda fase) e algumas de suas combinacoes. Foram utilizados 186 leitoes cruzados (D x LW), desmama

11. Perfil de eliminação de agentes infecciosos envolvidos em rinite na espécie suína / Elimination profile of infectious agents related with rhinitis in swine specie
Respiratory diseases are one of the largest cause of economic losses in swine industry, it is related with grown and weight gain reduction, mortality, vaccines and medicaments costs, veterinary assistance. In that context, rinithis cases have been a major contribution. The present study propose the determination of elimination profile of agents related with

12. Glutamine, glutamic acid and or yeast extract in the diet of weaned pigs / Glutamina, ácido glutâmico e ou extrato de levedura na dieta de leitoes desmamados
The present study aimed to evaluate the effects of the supplementation of different sources of protein concentrates, glutamine, acid glutamic and or yeast extract in diets of piglets from 26 to 44 days of age. At 22nd day of age, weaning day, 210 piglets, females and castrated males, crossbred of Landrace, Large White and Duroc races, with 6,79 kg average we
