Silva,Ariadne Maria Portilho Saturnino da; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Corassa,Anderson; Sarturi,Débora MinettiABSTRACT The objective of the present study was to evaluate the effects of cooling systems by negative pressure versus directed ducts on the performance of lactating sows and their litter. The experiment was conducted in a tropical climatic region in Brazil. Ninety-four lactating sows during 26.2±1.7 days of lactation were included with their 1,236 piglets. Sows were distributed using a completely randomized bl...
Dietary chromium yeast supplementation length in diets for growing-finishing pigs
Sanches,Danilo de Souza; Garcia,Elis Regina de Moraes; Rodrigues,Gabriela Puhl; Kiefer,Charles; Marçal,Danilo Alves; Alencar,Stephan Alexander da SilvaABSTRACT This study aimed to evaluate different periods of chromium yeast (CrY) supplementation on growth performance and quantitative carcass characteristics of growing-finishing pigs. We used eighty barrows (Duroc/Pietran × Large White/Landrace) with an initial body weight of 24.5±2.4 kg. A completely randomized block design was used within four periods of dietary CrY supplementation (control diet: CrY-free, ...
Guanidinoacetic acid supplementation on growth performance and molecular mechan...
Valini,Graziela Alves da Cunha; Duarte,Marcio de Souza; Rodrigues,Gustavo de Amorim; Veroneze,Renata; Saraiva,Alysson; Hausman,GaryABSTRACT: The objective with the present study was to evaluate the effect of guanidinoacetic acid (GAA) on the growth performance of nursery piglets as well as a possible molecular mechanism of action on lean mass gain. Seventy-two pigs, weaned at 21 d, weighing 6.80 ± 1.2 kg were distributed in a completely randomized design into one of three dietary treatments (control, control + 1.2 g/kg GAA or control + 2.4...
Combined supplementation of chromium-yeast and selenium-yeast on finishing barrows
Rodrigues,Gabriela Puhl; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Corassa,Anderson; Garcia,Elis Regina de Moraes; Marçal,Danilo AlvesABSTRACT: The present study was performed to evaluate the association of chromium-yeast and selenium-yeast as nutritional additives to enhance performance and quantitative characteristics in the carcass of finishing barrows. A total of 48 barrows, commercial hybrid, with initial weight of 68.3±3.5 kg and final weight of 99.6±3.6 kg, were utilized for the study. The animals were distributed in a randomized compl...
Effects of dietary nucleotide supplementation on growth performance and physiol...
Kreuz,Bruna Strieder; Rocha,Gabriel Cipriano; Campos,Paulo Henrique Reis Furtado; Fonseca e Silva,Fabyano; Hannas,Melissa IzabelABSTRACT The objective of this study was to evaluate the effects of dietary nucleotide supplementation on growth performance, serum immunoglobulin G (IgG) and uric acid levels, immune-related organs, and intestinal morphometric parameters of broiler chickens under pre- and post-inflammatory challenge with lipopolysaccharide (LPS). Ninety-six seven-day-old male broiler chicks were randomized in a 2×2 factorial d...
Effects of corn processing on piglet performance and intestinal parameters
Scalco,Tiago; Valini,Graziela Alves da Cunha; Silva,Caroline Brito da; Calderano,Arele Arlindo; Rodrigues,Gustavo de AmorimABSTRACT The objective of the present study was to compare the effects of corn processing on performance and intestinal parameters of weanling piglets. To accomplish our goal, 42 piglets (21 days-old, 7.18±1.0 kg body weight) were randomly allocated (seven pens/treatment; three pigs/pen) to one of two treatments: ground corn – corn ground through a hammer mill with a 1.0-mm screen after being ground by a hammer...
Ractopamine concentration on the lipid profile of swine fat and meat
Alencar,Stephan Alexander da Silva; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Viana,Luiz Henrique; Gonçalves,Liliane Maria PianoABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The ...
Net energy levels on the lipid profile of pork
Alencar,Stephan Alexander da Silva; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Viana,Luiz Henrique; Gonçalves,Liliane Maria PianoABSTRACT: This study was conducted to evaluate the effects of net energy levels on the lipid profile of adipose tissue and muscle of swines. A total of 90 animals, with initial weight of 71.94±4.43kg, were used, and distributed in a randomized block design in five net energy levels (2,300, 2,425, 2,550, 2,675, and 2,800Kcal kg-1 feed), with nine replicates and two animals per experimental unit. Lipid profiles o...
Yeast extract plus blood plasma in diets for piglets from 36 to 60 days old
Pereira,Cinthia Maria Carlos; Donzele,Juarez Lopes; Donzele,Rita Flávia Miranda de Oliveira; Kiefer,Charles; Bernardino,Verônica Maria PereiraABSTRACT: To evaluate inclusion levels and residual effects of diets containing yeast extract (YE) plus blood plasma (BP) on the performance of 36 to 60-days old piglets, 105 piglets were used (8.75±0.72kg), and they were distributed under a randomized block experimental design with five treatments (control - 2.0% BP; 1.0% BP plus 0.0, 1.0, 2.0, or 3.0% YE), seven repetitions, and three animals per experimental...
Evaluation of acid digestion techniques to estimate chromium contents in cattle...
Rocha,Gabriel Cipriano; Palma,Malber Nathan Nobre; Detmann,Edenio; Valadares Filho,Sebastião de CamposThe objective of this work was to evaluate the accuracy of digestion techniques using nitric and perchloric acid at the ratios of 2:1, 3:1, and 4:1 v v-1, in one- or two-step digestion, to estimate chromium contents in cattle feces, using sodium molybdate as a catalyst. Fecal standards containing known chromium contents (0, 2, 4, 6, 8, and 10 g kg-1) were produced from feces of five animals. The chromium conten...
