Silagem de grãos úmidos de milho na alimentação de frangos de corte

O objetivo deste trabalho foi avaliar a silagem de grãos úmidos de milho (SGUM) como ingrediente nas rações de frangos de corte, em substituição total aos grãos secos de milho (GSM), no desempenho, no rendimento da carcaça, no peso dos órgãos e na morfologia intestinal. No primeiro experimento, 600 pintainhos machos Ross foram distribuídos em blocos casualizados, com seis tratamentos (A: GSM de 1-42 dias; B: SGUM de 1-42 dias; C: SGUM de 1-7 dias e GSM de 8-42 dias; D: SGUM de 1-14 dias e GSM de 15-42 dias; E: SGUM de 1-21 dias e GSM de 22-42 dias; F: GSM + água de 1-42 dias), com quatro repetições, de 25 aves. No segundo experimento, foram utilizados 24 pintainhos machos Ross, distribuídos ao acaso, em dois tratamentos (com e sem SGUM) e 12 repetições cada. A SGUM até 21 dias de idade não interferiu no desempenho das aves e no rendimento de carcaça aos 42 dias de idade. Frangos alimentados com SGUM apresentaram maior peso relativo do fígado, menor largura das vilosidades do duodeno e íleo, maior altura de vilosidade no jejuno aos 21 dias, e menor profundidade de cripta no duodeno e no íleo aos 42 dias de idade. A SGUM pode ser considerada um ingrediente em dietas de frangos de corte até 21 dias de idade, por não interferir no peso final das aves, no rendimento de carcaça e peso dos órgãos.

Phentolamine bioequivalence study

Objective: To assess the bioequivalence of 2 tablet formulations of phentolamine (Regitine phentolamine 40 mg tablet formulation by Novartis, Brazil, as test formulation, and Vasomax, phentolamine 40 mg tablet formulation by Schering Plough S.A., Brazil, as reference formulation). Methods: A single 40 mg oral dose of each formulation was administered to 36 male healthy volunteers. The study was conducted after screening, using an open, randomized, 2-period crossover design, a 7-day interval between doses, and wash-out period of at least 4 weeks. Plasma samples for determination of phentolarnine were obtained predose and at intervals over 720 min postdose. Plasma concentrations were quantified by reversed-phase liquid chromatography coupled to tandem mass spectrometry (LC-MS-MS) with positive ion electrospray ionization using multiple reactions monitoring (MRM) method. Precision of the method was evaluated using calibration curves and plasma quality control samples. The subjects were monitored throughout the study. Systolic and diastolic blood pressure and pulse rate measurement were taken predose and at intervals up to 720 min. Tolerance of both products was good. No serious adverse reactions were reported. The pharmacokinetic parameters calculated for both compounds included: AUC((0-720 min)), AUC((0-infinity)), C-max,C- C-max/AUC((0-720 min),) t(max), t(1/2) and k(c). Results: the maximum concentrations reached (Cmax) were compared. Regitine 40 mg formulation C-max geometric mean ratio was 108.29% (90% Cl = 98.58 - 118.96) of Vasomax 40 mg formulation. The areas under the curve (AUC((0-720 min))) were compared. Regitine 40 formulation (AUC((0-720 min)) geometric mean ratio was 102.33% (90% Cl = 97.21 - 107.72) of Vasomax 40 mg formulation. Conclusion: Since the 90% Cl for both Cmax and AUC ratio where inside the 80 to 125% interval proposed by the Food and Drug Administration, it is concluded that Regitine 40 mg tablet is bioequivalent to Vasomax for the rate and extent of absorption.

Estrutura do capim-braquiária durante o diferimento da pastagem

This experiment was performed aiming to evaluate tiller population density, forage mass and its morphological components on pastures of Brachiaria decumbens cv. Basilisk. during deferment. The treatments encompassed four deferred grazing periods (18, 46, 74 and 121 days). A randomized block design with two replications was used. The numbers of vegetative tillers (VT), reproductive tillers (RT) and dead tillers (DT) in the pasture were determined. The masses of green leaf blade (GLBM), dead stem (DSM) and dead forage (DFM) were also determined. There was a reduction in the number of VT (from 1, 491 to 944 tiller m-2) during the deferment period. RT and DT numbers were not influenced by the deferment periods. Their averages were 211 and 456 tiller m-2, respectively. Longer deferring periods resulted in an increase in GSM (from 2, 965 to 4, 877 kg ha-1 of dry mass) and DFM (from 2, 324 to 4, 823 kg ha-1 of dry mass), but it did not influence GLBM (average of 2, 047 kg ha-1 of dry mass). In Viçosa, Minas Gerais State Brazil, Brachiaria decumbens cv. Basilisk pasture fertilized and deferred in the beginning of March must be kept deferred for about 70 days in order to conciliate both quality and quantity forage production.

Substituição dos grãos secos de milho pela silagem de grãos úmidos de milho para vacas da raça holandesa em lactação

In order to evaluate the effects of replacement of dried corn (GSM) for silage moisture corn (HMCS) on production and milk composition were used five Holstein cows, primiparous with a mean of 112 days post delivery, confined in Tie Stall, for 70 days. We used five diets according to NRC to 17.5% CP (DM) and 2.4 Mcal / kg DM, the 40:60 ratio of roughage and concentrate containing soybean meal, sugar cane silage and hay and substitution levels of the GSM HMCS the following treatments: a) 0%, 2) 25%, 3) 50%, 4) 75% and 5) 100%. Milk production and dry matter intake (DMI) were recorded daily. The animals were milked daily 6:00 and 18:00 h, and milk samples collected from consecutive milkings of each experimental period of 14 days (four days of collection). The experimental design was a 5x5 Latin square and the data analyzed by the statistical program SAS. Body weight (508 kg), milk (23.6 kg), corrected milk (22.7 kg), DMI (17.13 kg) showed no significant difference, but the intakes of neutral detergent fiber (6.67 kg), and detergent acid (3.39 kg), feed efficiency for the production of milk (milk 1.41 kg / day) urea nitrogen (17.67 mg / dL) differ, thus indicating that HMCS is more efficient than GSM in the diet of dairy cows not alter the production and milk composition.
