The objective of this study was to evaluate the effect of adding different doses of insulin to swine semen processed and stored at 15 ºC. The experiment used sixteen ejaculates from four commercial breeding pigs, distributed in a randomized block design (ejaculate) with split plot along time (0, 24, 48 and 72 hours of storage) with four treatments (insulin levels - 0.0 4.0 8.0 and 12.0 IU per dose) and 16 repetitions. The experimental unit was made of two insemination doses of 100 mL each, with 3×10(9) spermatozoids. Insulin used was NPH-human, added at the time of processing the doses. The addition of insulin did not affect motility, sperm viability, the percentage of abnormal cells, the osmotic resistance or the degradation rate of motility in 120...

The objective of this work was to evaluate the use of vegetable extract based addictives associated or not to symbiotics as an alternative for antibiotic as growth promoters for piglets at initial phase. It was used 125 pigs of commercial genetic line with initial weight of 7.4 ± 1.1 kg, weaned at 20 days of age, during 50 days. The experimental design used was randomized blocks (initial weight), with five treatments and five replicates with five animals per experimental unit. The experimental diets were a basal diet, without additive, and other four diets, one diet containing antibiotic (colistin + zinc oxide); diet with 0.3% of a symbiotic mixture; diet with 0.3% of a symbiotic mixture plus 0.05% of herbal mix (plant extracts and microencapsulated...

Autores: Alvarenga,Renata Ribeiro; Rodrigues,Paulo Borges; Cantarelli,Vinícius de Souza; Zangeronimo,Márcio Gilberto; Silva Júnior,José Walter da; Silva,Leonardo Rafael da; Santos,Luziane Moreira dos; Pereira,Luciano José.
The objective of this study was to determine the chemical and energy composition of spirulina (Spirulina platensis), the nutrient metabolizability coefficients, and the values of apparent metabolizable energy (AME) and the apparent metabolizable energy corrected for nitrogen balance (AMEn) in broilers. A digestibility trial was carried out by using total excreta collection method, with 90 Cobb 500 lineage chicks, with initial weight of 256 ± 5 g at 11 days of age. Birds were allotted in metabolic cages for 10 days, distributed in a completely randomized design, with three treatments and six repetitions with five birds each. Diets consisted on a reference-ration based on corn and soybean meal and two test diets, one containing spirulina (30%) and the other...

Provedor de dados: 96
Autores: Teles,Mariele Cristina; Pereira,Bárbara Azevedo; Rocha,Luiz Gustavo Pessoa; Resende,Carla Oliveira; Rodrigues,Valéria Vânia; Pereira,Luciano José; Rodríguez-Gil,Joan Enric; Zangeronimo,Márcio Gilberto.
ABSTRACT The objective of this study was to evaluate the putative effects of the use of coffee husk as floor covering on boar semen quality. Sixteen boars were divided into two groups. The first group was held in a conventional system with a compact floor. The second group was kept on a compact floor covered with coffee pods. The experimental period was 60 days. Levels of caffeine and chlorogenic acid in the insemination doses (ID) before and after 96 h of storage at 15 °C and the reproductive performance (litter size and rate of return to estrus) of these doses after their utilization in a standard artificial insemination protocol were evaluated. The ID from the animals kept in pens containing the coffee pods contained 25.4±8.7 µg/mL of caffeine, whereas...

Metabolic and behavioral effects of ractopamine at continuous low levels in rats under stress
Provedor de dados: 52
Autores: Lopes,Edna; Sousa,Raimundo Vicente de; Zangeronimo,Márcio Gilberto; Pereira,Andressa Naira de Jesus; Coelho,Mariana de Resende; Ferreira,Matheus Soares da Silva; Lima,Renato Ribeiro; Marcondes,Fernanda Klein; Napimoga,Marcelo Henrique; Pereira,Luciano José.
This study aimed at evaluating the effect of ractopamine (RAC) on metabolism, zootechnical performance, body composition, and behavior in Wistar rats submitted to acute and chronic restrain stress. The oral dose of 5 mg/kg of RAC was administered in periods of 0, 7, 14, 21, and 28 days. The elevated plus-maze test (EPMT) was used for behavioral assessment. Blood, carcass and viscera characteristics were evaluated. Insulin-dependent glucose transporters (GLUT-4) were semi-quantified by Western Blot in epididymal adipocytes. RAC periods associated with chronic stress increased the GLUT-4 protein expression in adipose tissue in a time-dependent manner (P=0.01), i.e., the longer the RAC addition period, the higher the GLUT-4 concentration in chronically...

The objective of this study was to evaluate the influence of integral and decaffeinated coffee brews (Coffea arabica L and C. canephora Pierre) on the metabolic parameters of rats fed with hyperlipidemic diet. Thirty male Wistar rats (initial weight of 270 g ± 20 g) were used in the study, which were divided into six groups five each. The treatments were normal diet, hyperlipidemic diet, hyperlipidemic diet associated with integral coffee arabica or canephora brews (7.2 mL/kg/day) and hyperlipidemic diet associated to decaffeinated arabica, or canephora brews, using the same dosage. After 41 days, performance analyses were conducted.The rats were then euthanized and the carcasses were used for the analysis of dried ether extract and crude protein....

Autores: Ferreira,Matheus Soares da Silva; Garbossa,Cesar Augusto Pospissil; Oberlender,Guilherme; Pereira,Luciano José; Zangeronimo,Márcio Gilberto; Sousa,Raimundo Vicente de; Cantarelli,Vinícius de Souza.
The aim of this article was to evaluate the in vivo mechanism of action through which ractopamine reduces the amount of adipose tissue in carcass of animals fed diets supplemented with this drug. Literature search was carried out, using the keywords Ractopamine, lipogenesis, lipolysis, fatty acid and adipose tissue. The scoring system was designed for the adequacy of the methodology. A total of eight papers were found - all published in the English language. The determination of lipolysis and lipogenesis was carried out using different methods - from the quantification of non-esterified fatty acids in the blood to molecular analyses of adipose tissue. The review analysis suggested that, at least in the pigs, the use of this drug reduced lipid deposition in...

Provedor de dados: 52
Autores: Silva,Viviam de Oliveira; Foureaux,Renata de Carvalho; Araujo,Thiago Santos; Peconick,Ana Paula; Zangeronimo,Marcio Gilberto; Pereira,Luciano José.
The probiotic influence on the immune system, especially under pathogenic challenge conditions, still remains controversial. To address this, a systematic review of current studies concerning the efficacy of probiotics on the immune response of rats subjected to experimental challenges was conducted. The survey was conducted using PubMed, ISI Web of Science and Scielo databases. Only studies which tested probiotics in vivo in rats were included. The experimental design, methodological quality, and results of the articles were analyzed. In total 21 articles were selected for this study. The most commonly used microorganisms in the experiments were those of the genus Lactobacillus, which was reported in 12 articles. The second most often used genus was...

In vitro bacterial plaque suppression and recolonization by S. mutans and S. sobrinus
Provedor de dados: 58
Autores: Pereira,Cássio Vicente; Pereira,Luciano José; Gonçalves,Reginaldo Bruno; Höfling,José Francisco.
The in vitro study of the interactions between S. mutans and S. sobrinus is important to determine the role of these microorganisms in the formation of biofilms on dental structures and their potential to induce carious lesions. The objective of this research was to study the suppression of bacterial plaque formation and its recolonization by rifampycin-resistant S.mutans and streptomycin-resistant S. sobrinus. To study the competitive relationship between these species, previously standardized strains were incubated in media containing different fermentable carbohydrates. At determined time intervals, samples were collected from mixed cultures of S. mutans and S. sobrinus, diluted and plated on BHI-agar containing rifampycin or streptomycin to determine...
