1. Influence of fermented fish meal supplementation on growth performance, blood metabolites, and fecal microflora of weaning pigs
ABSTRACT This study was conducted to estimate the effect of dietary supplementation with fermented fish meal on growth performance, blood metabolites, and fecal microflora in weaning pigs. A total of 180 weaned pigs ((Landrace ×Yorkshire) × Duroc; with average body weight of 6.0 kg) were randomly distributed among three dietary treatments (0, 0.2, and 0.5%

2. Inorganic and organic trace mineral supplementation in weanling pig diets
Um estudo foi conduzido para avaliar os efeitos de microminerais inorgânicos e orgânicos na dieta em dois níveis de suplementação, sobre desempenho, ocorrência de diarreia, parâmetros hematológicos, excreção dos minerais nas fezes e retenção dos minerais nos metacarpos e fígado de leitões desmamados. Setenta leitões desmamados aos 21 dias de i

3. Óleo de arroz na alimentação de leitões recém-desmamados / Rice oil in weanling pig diet
A inclusão de óleos em dietas de leitões recém-desmamados tem por finalidade aumentar a densidade energética para atender às exigências energéticas dos leitões. Foram realizados dois experimentos para avaliar a inclusão do óleo semirrefinado de arroz como substituto ao óleo refinado de soja em dietas de leitões recém-desmamados. O Experimento 1

4. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o

5. Produção e avaliação de plasma bovino desidratado como ingrediente de rações de leitões desmamados precocemente. / Production and evaluation of plasma dehydrated as an ingredient in cattle rations of early weaners.
The objective of this work was to obtain spray dried bovine plasma (SDBP) and to compare it with a commercial one (CSDBP) as feed ingredients of weanling pigs (weaned at 21 days of age) based on performance, blood and plasma components, liver and spleen glutathione levels, small intestine morphology and diarrhea score. Blood of healthy bovines was collected

6. Antimicrobial agents, probiotics, prebiotics and herbal extracts as growth promoters of weanling pigs / Utilização de agentes antimicrobianos, probióticos, prebióticos e extratos vegetais como promotores do crescimento de leitões recém-desmamados
The purpose of this work was to evaluate the probiotics, prebiotics and herbal extracts as alternatives to antimicrobial agents as growth promoters of weanling pigs, based on the morphometry of organs, fecal score, intestinal microbiology, intestinal histology, nutrient digestibility and performance. Two randomized complete block design experiments were carr

7. Spray-dried egg for weanling pigs. / O ovo em pó na alimentação de leitões recém-desmamados.
Foram realizados dois experimentos para determinar a composição química, os coeficientes de digestibilidade de nutrientes e os valores de energia e proteína digestíveis do ovo em pó (OP) e avaliar o desempenho e os componentes sanguíneos e plasmáticos de leitões recém-desmamados alimentados com dietas contendo níveis crescentes de proteína do OP

8. Isolation and partial characterization of two different heat-stable enterotoxins produced by bovine and porcine strains of enterotoxigenic Escherichia coli.
Heat-stable enterotoxins (ST-124 and ST-1261) have been isolated from two different enterotoxigenic Escherichia coli of bovine (124) and porcine (1261) origin. The enterotoxin preparations were isolated by ultrafiltration and ion-exchange chromatography and were both active in the suckling mouse test and pig ligated loop test in the nanogram range. The bovin

9. Phenotype and genotype of Escherichia coli isolated from pigs with postweaning diarrhea in Hungary.
A total of 205 Escherichia coli isolates from 88 diarrheal weanling (4- to 10-week-old) pigs from 59 farms were tested by slide agglutination for K88, K99, F41, and 987P antigens. K88 antigen was detected in 61% of the isolates representing 60% of the pigs and 56% of the farms. K88 antigen was associated with serogroup O149 and 91% of the K88+ isolates. K99,

10. Reversal of the biological activity of Escherichia coli heat-stable enterotoxin by disulfide-reducing agents.
Various disulfide-reducing agents, mostly thiols and thiol precursors, were examined for their ability to reduce the disulfide bonds in the Escherichia coli heat-stable enterotoxin STa; reduction of the bonds results in loss of biological activity. The biological activity measured was the stimulation of guanylate cyclase in pig intestinal brush border membra

11. Neutrophil response and function during acute cytomegalovirus infection in guinea pigs.
The mobilization and functional characteristics of polymorphonuclear leukocytes (PMNs) at the site of an inflammatory stimulus were studied during acute cytomegalovirus infection in guinea pigs. Weanling Hartley strain guinea pigs were inoculated subcutaneously with approximately 10(6) 50% tissue culture infective doses of virulent salivary gland-passaged gu

12. R Factor Transmission In Vivo1
Experimental infections were induced in weanling pigs orally both with nalidixic acid (NA)-sensitive and -resistant strains of Salmonella choleraesuis var. kunzendorf, designated RC221 and RC221NA, respectively. Prior to the time of infection, cultures of normal bacterial flora were isolated from swine fecal matter and screened for the presence of R factors.
