1. Acidifiers blend on digestibility, blood metabolites and performance of nursery piglets
RESUMO O objetivo deste estudo foi avaliar o efeito da inclusão de dois acidificantes (com diferentes níveis de proteção) sobre o potencial de acidificação in vitro, a digestibilidade aparente do trato total dos nutrientes da dieta, os metabólitos sanguíneos e o ganho médio diário de leitões. Foram avaliados dois acidificantes comerciais (AC1 e AC

2. Oral Administration of Citrus Extracts in Suckling Piglets
Abstract An experiment was conducted to evaluate the performance of suckling piglets subjected to oral administration of citrus extracts (CE). Twenty sows were used with ten sucking piglets on average initial weight of 1.26 kg (± 0.32) for 21 days. The experimental design was a randomized complete block design with two treatments: Negative Control (without

3. Desempenho e termorregulação de porcas lactantes alojadas em diferentes localizações no interior de um galpão com sistema de resfriamento evaporativo em ambiente tropical
ABSTRACT The effects of housing lactating sows at different locations in a shed with evaporative cooling system (ECS) on their thermoregulation and reproductive and productive performance of the sow and the litter in summer were determined. 34 females were used in the three lines of cages at these locations: near the pad cooling; in the middle of the shed an

4. Phenotypic correlation of characteristics in the gilt performance test with an average number of live-born piglets through all achieved births, during the reproductive exploitation
RESUMO A eficácia reprodutiva das porcas dita o nível de rentabilidade da própria produção, e o momento do teste e seleção de leitoas para reprodução (como os pais de uma geração futura) representa um momento muito importante. Dado o fato de que a seleção de leitoas para criação é parcialmente baseada no ganho de peso no teste, neste estudo e

5. Dietary fiber and zinc additives on performance and intestinal health of Escherichia coli challenged piglets
ABSTRACT This study aimed to evaluate the effects of zinc oxide and a low level of encapsulated zinc oxide, with or without dietary fiber, on the performance and intestinal health of weaned piglets. A total of 112 piglets were used, divided into four treatment groups: basal diet with zinc oxide (ZnO); basal diet with zinc oxide and dietary fiber (ZnO+DF); ba

6. Effect of observed individual data of performance and excretion on life cycle assessment of piglets
ABSTRACT: The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replica

7. Increased urinary losses in piglets fed diets containing high levels of glycerin
ABSTRACT This study evaluated the nutritional value of glycerin added to diets of weaned piglets and its effects on animal performance and urinary losses. Weaned piglets were individually housed in metabolic cages and fed diets in which a basal diet containing lactose (Gly0) was replaced by 50 (Gly50), 100 (Gly100), or 150 g kg−1 (Gly150) of glycerin; or a

8. Reproductive performance of fixed-time artificial insemination in swine and factors for the technology success
RESUMO: A inseminação artificial em tempo fixo (IATF) surge como uma biotecnologia para definir o melhor momento para realizar uma única IA, reduzindo o número de células espermáticas por fêmea inseminada. Os protocolos de IATF podem se basear na detecção do estro ou na data de desmame e têm como objetivo sincronizar a ovulação a partir do uso de

9. Creep feeding improves growth performance of suckling piglets
ABSTRACT The present study evaluated the optimal duration of creep feeding that improves the growth performance and fecal score of piglets and the performance and estrus interval of sows. Sixteen sows (Yorkshire × Landrace) and their litters were used in this 24-day trial. Dietary treatments were: Treatment 1, in which creep feed was not provided; treatment

10. Feed additives can differentially modulate NF-κB (RelA/p65), IGF-1, GLUT2, and SGLT1 gene expression in porcine jejunal explants
ABSTRACT The intestinal gene expression of RelA/p65 (NF-κB), insulin growth factor 1 (IGF-1), glucose transporter 2 (GLUT2), and Na+/dependent glucose transporter 1 (SGLT1) were evaluated in response to benzoic acid, yeast culture, L-glutamine, and oregano essential oil, using an ex vivo model. Six piglets weighing approximately 20 kg each were sacrificed,

11. Correlation between urinary tract infection and reproductive performance of sows
ABSTRACT This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an ex

12. 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
