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. USE OF PUPILLOMETRY IN THE DIAGNOSIS OF STRESS IN PIGLETS TRANSPORTED IN A TROPICAL CLIMATE
ABSTRACT The objective of this study was to evaluate the reactivity of the pupillary area (PA) as a non-invasive method for diagnosing stress in piglets submitted to transport. A total of 10 journeys were monitored and grouped according to the transport distance (15 and 75 km). Were sampled 360 piglets (25±3.8 kg) to measure the PA, body temperature (BT), a

3. BEHAVIORAL RESPONSES OF PIGS FINISHED IN DEEP BEDDING AND CONVENTIONAL BED SYSTEMS
ABSTRACT The objective of this study was to characterize the thermal environment and evaluate the behavior of finishing pigs housed in deep bedding and conventional systems. The work was carried out in the Department of Animal Science of the Federal Institute of Education, Science and Technology of Southeast Minas Gerais, Rio Pomba campus. Three pens were us

4. USING SOUNDS PRODUCED BY PIGS TO IDENTIFY THERMONEUTRALITY ZONES FOR THERMAL ENVIRONMENT ASSESSMENT RATIOS
ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nurser

5. 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

6. Hemodynamic variables in piglets anesthetized with isoflurane or propofol, kept under spontaneous ventilation and FIO2 of 0.5
RESUMO O objetivo deste estudo foi avaliar comparativamente os efeitos do propofol ou do isoflurano sobre as variáveis hemodinâmicas em leitões que receberam fração inspirada de oxigênio (FIO2) de 0,5 sob ventilação espontânea. Dezesseis leitões, pesando 16±1,1kg, foram divididos aleatoriamente em dois grupos: GI (isoflurano e FIO2 de 0,5) e GP (p

7. 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

8. 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

9. 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

10. Dietary iron chelate for sows and effects on iron supplementation in piglets
Abstract: In order to evaluate iron chelate in diets for sows during gestation and lactation and its effects on iron supplementation for piglets, a total of 50 pregnant sows in the third parity order were distributed according to a randomized block design with two treatments: diet without iron chelate supplementation (n=20); diet supplemented with 0.15% of i

11. Outbreaks of nutritional cardiomyopathy in pigs in Brazil
RESUMO: Cardiomiopatia dilatada (CMD) é uma condição que afeta o miocárdio, raramente relatada em porcos. A DCM é caracterizada por dilatação ventricular, que resulta em disfunção sistólica e disfunção diastólica secundária e pode levar a arritmias e insuficiência cardíaca congestiva fatal. Este estudo descreve os achados clínicos, patológi

12. 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
