Two experiments were carried out with twenty-four male weaned Holstein calves to verify the influence of different dietary cation-anion concentrate and roughage proportions on calves metabolism. In the first experiment, calves were fed rations with -100, +200 and +400 mEq cation-anion balance/kg of dry matter, containing 60% of roughage and 40% of concentrate. In the second experiment, calves (117.6±20.8 kg average weight) received rations with similar dietary cation-anion balance but in diets of 40% roughage and 60% concentrate. As the dietary cation-anion balance became more positive, there was a quadratic response of blood pH in both diets with 60 and 40% roughage. A linear increase following increased dietary cation-anion balance was observed on...

Efeito do manejo de aleitamento nos níveis de cortisol no metabolismo e na produção de leite de vacas holandesas
Provedor de dados: 96
Autores: Paiva,Fernanda Alves de; Negrão,João Alberto; Saran Netto,Arlindo; Porcionato,Marco Aurélio de Felicio; Lima,César Gonçalves de.
Avaliou-se a influência do manejo de aleitamento nos níveis de cortisol, no metabolismo e na produção de leite de vacas leiteiras. Utilizaram-se 18 vacas holandesas e seus bezerros alocados em três tratamentos: T1: as vacas foram separadas dos bezerros 6 horas após o parto, sendo mantidas com suas crias 60 minutos por dia nos três primeiros dias; T2: as vacas foram separadas dos bezerros 6 horas após o parto; T3: as vacas foram mantidas com seus bezerros durante os três primeiros dias de lactação, exceto no momento das ordenhas. Foram coletadas amostras de sangue 168 horas antes do parto, no dia do parto (0 hora) e 24, 48, 72 e 96 horas após o parto para a determinação de glicose, triglicerídeos, proteína total e cortisol. A produção leiteira foi mensurada...

Supplementation of diets for Santa Ines sheep with organic and inorganic zinc sources
Provedor de dados: 96
Autores: Vilela,Flávio Garcia; Zanetti,Marcus Antonio; Saran Netto,Arlindo; Freitas Júnior,José Esler de; Rennó,Francisco Palma; Venturelli,Beatriz Conte; Canaes,Taissa de Souza.
This research was conducted with objective to evaluate the effect of different zinc (Zn) sources and doses in the diet for Santa Ines sheep. Forty lambs at weaning, with 18.4 kg of body weight were supplemented with three different sources of zinc (zinc oxide (ZnO), zinc amino acid and zinc proteinate) and three doses of zinc (200, 400 and 600 mg/kg DM) added to the basal diet. At every 28 days, animals were weighted and blood samples were collected for analyses of zinc (Zn), alkaline phosphatase and immunoglobulin G (IgG) and M (IgM). At the end of experiment, liver samples were collected for determination of the hepatic zinc levels. Zinc was analyzed with atomic absorption spectrophotometer, while phosphatase alkaline and immunoglobulins G and M were...

Roughage-free finishing diet based on whole corn grain and a mixture of additives for Nellore heifers
Provedor de dados: 96

ABSTRACT This study was carried out to evaluate the effect of a blend of additives (choline, methionine, selenium, and organic zinc) on performance, feed efficiency, rumen parameters, and carcass traits of Nellore heifers finished with roughage-free diet. Nellore heifers (n = 36; average BW = 244±24.1 kg; average 24 months of age) were maintained in a feedlot system for 86 d. Heifers were separated into two groups: control and additive. Heifers in control group were fed a based diet composed of 850 g kg−1 corn grain and 150 g kg−1 of a mineral-vitamin-protein pellet. The additive group was fed a diet supplemented with a blend of choline, methionine, selenium, and organic zinc at 1,667, 4,000, 1, and 24.37 mg kg−1 of the diet dry matter, respectively. The...

Accuracy, precision and robustness of different methods to obtain samples from silages in fermentation studies
Provedor de dados: 96
Autores: Gomes,Rodrigo da Costa; Meyer,Paula Marques; Castro,Ari Luiz de; Saran Netto,Arlindo; Rodrigues,Paulo Henrique Mazza.
The objective of this study was to evaluate accuracy, precision and robustness of two methods to obtain silage samples, in comparison with extraction of liquor by manual screw-press. Wet brewery residue alone or combined with soybean hulls and citrus pulp were ensiled in laboratory silos. Liquor was extracted by a manual screw-press and a 2-mL aliquot was fixed with 0.4 mL formic acid. Two 10-g silage samples from each silo were diluted in 20 mL deionized water or 17% formic acid solution (alternative methods). Aliquots obtained by the three methods were used to determine the silage contents of fermentation end-products. The accuracy of the alternative methods was evaluated by comparing mean bias of estimates obtained by manual screw-press and by...
