1. Phytogenic as feed additive for suckling dairy calves’ has a beneficial effect on animal health and performance
Abstract: The aim of this study was to evaluate whether the use phytogenic as feed additive of Holstein calves could exert beneficial effects on animal health and performance. Thirty newborn calves were randomly divided into two groups (control and treated), and the treated consisted of 10 g of the phytogenic product diluted in milk once a day for 30 days. B

2. Determination of methanol residues in crude glycerol for animal feed by gas chromatography
ABSTRACT: Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodiesel, yet few have been described that identify the methanol level in crude glycerol. We propose

3. 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,

4. Effects of lines and inoculants on nutritive value and production costs of triticale silages
ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity

5. Combined use of ionophore and virginiamycin for finishing Nellore steers fed high concentrate diets
Zebu cattle fed high concentrate diets may present inconsistent performance due to the occurrence of metabolic disorders, like acidosis. The isolated use of ionophores and virginiamycin in high grain diets can improve animal performance and reduce the incidence of such disorders, but recent studies suggested that their combination may have an additive effect

6. Ractopamine as a metabolic modifier feed additive for finishing pigs: a review
The β-adrenergic agonist ractopamine is increasingly used in the swine industry due to higher consumer demand for leaner pork products. Redirecting nutrients to favor leanness rather than fat deposition, ractopamine improves growth and carcass traits of finishing pigs. However, the impact of this agonist on pork quality is not clearly defined. Understanding

7. Ractopamine in diets for finishing pigs of different sexual categories
Performance and carcass and cut yield of finishing pigs of three sexual categories fed diets with different levels of ractopamine were studied. Forty-eight hybrid animals (initial weight of 92.1±2.4 kg) were distributed in a completely randomised design in 3 × 2 factorial arrangement (three sexual categories: surgically castrated males, two females and imm

8. Avaliação de antimicrobianos como promotores de crescimento via mistura mineral para bovinos de corte em pastejo / Antimicrobial growth promoters in mineral mixtures for grazing beef cattle
Antimicrobials which modifies rumen fermentation can improve economical efficiency of beef cattle grazing systems and reduce its possible impacts on the environment. It was conducted a series of experiments with the objective of evaluating free-choice mineral mixtures as an antimicrobial delivery system for grazing animals. On experiment 1, at Piracicaba-SP,

9. Studies with sanguinarine like alkaloids as feed additive in broiler diets
This research included two studies evaluating the live performance of broilers fed Sangrovit® (minimum of 1.5% sanguinarine, a quaternary benzo[c]phenanthridine alkaloid extracted from Macleaya cordata). Both studies were conducted using Ross 308 female broiler chicks. Birds were fed corn-soybean meal all-vegetable diets without growth promoters with 5 trea

10. Development and validation of methods for analysis of ractopamine in raw material, feed additive Ractosuin®, vitamin-mineral complex and ration for swine in termination. / Desenvolvimento e validação de métodos para análise de Ractopamina na matéria-prima, no produto Ractosuin®, no complexo vitamínico-mineral e na ração para suínos em terminação
Muitos fármacos, principalmente os agonistas B-adrenérgicos, vêm sendo utilizados na produção animal e, devido às novas formas de pecuária intensiva, sua utilização tem crescido exponencialmente. Dentre os agonistas B-adrenérgicos, a Ractopamina (RAC) é o mais utilizado como agente repartidor de nutrientes, pois promove ganho de peso, eficiência

11. Níveis de ractopamina nas dietas de suínos machos castrados na fase de terminação / Ractopamine levels in diet for finishing borrows
The swine production in Brazil has become in recente years, a highly dynamic activity, because the consumer is getting increasingly demanding especially with rescpet to the product it consumes. This fact, coupled with the need for the producer to remain in business, have meant that people involved in the chain pig were in constant learning and the search for

12. GLICOMANANO ESTERIFICADO EM RAÇÕES PARA FRANGOS CONTENDO MILHO OU SORGO EXPERIMENTALMENTE CONTAMINADAS POR FUNGOS OU COM AFLATOXINA B1 / GLICOMANANO esterified into diets of broiler chickens containing corn or sorghum EXPERIMENTALLY INFECTED BY FUNGI OR AFLATOXIN B1
Two experiments were conducted with 960 Cobb 500 chicks raised in battery heated to 21 days. In the first experiment, birds were fed diets with corn and sorghum non-musty and moldy, or not treated with the mycotoxin adsorbent based glicomanano ester (GME) at concentrations of 0 and 0.1% of the diet. The experiment was conducted in a completely randomized in
