Inclusion of grape pomace in the diet of pigs on pork quality and oxidative stability of omega-3 enriched fat Ciência Rural
Bertol,Teresinha Marisa; Ludke,Jorge Vitor; Campos,Rogerio Manoel Lemes de; Kawski,Vicky Lilge; Cunha Junior,Anildo; Figueiredo,Elsio Antonio Pereira de.
ABSTRACT: The objective of this study was to assess the effects of including grape pomace in the diet of pigs on pork quality and oxidative stability of body fat enriched with omega-3 fatty acids. Four treatments were compared: T1) Control diet based on corn and soybean meal; T2) Diet with inclusion of 3% of a canola (50%) and flaxseed (50%) oil blend; T3) Diet with inclusion of 3% of the oil blend and sequential levels of 3 and 5% of grape pomace; T4) Diet with inclusion of 3% of the oil blend and sequential levels of 6 and 10% of grape pomace. Inclusion of grape pomace in the diet led to an increase (P<0.10) of a* value and color saturation index of meat. The omega-3 and polyunsaturated fatty acids (PUFA) content of backfat were increased (P>0.10)...

Investigation of glutathione peroxidase activity in chicken meat under different experimental conditions Ciênc. Tecnol. Aliment.
Cichoski,Alexandre José; Rotta,Renata Bezerra; Scheuermann,Gerson; Cunha Junior,Anildo; Barin,Juliano Smanioto.
Due to the fact that previous studies on the enzymatic activity of Glutathione peroxidase (GSH-Px) diverge widely in their methodology and results, this study aimed to investigate the influence of different analytical conditions on GSH-Px activity in chicken thighs from broilers that were fed different diets with different sources and concentrations of selenium. GSH-Px activity was evaluated six hours after slaughter and 120 days after frozen storage at -18 ºC. The different analytical conditions included time of pre-incubation (0, 10 and 30 minutes), reaction medium, types of substrate (H2O2 (0.72 mM, 7.2 mM, and 72 mM) and Terc-butil hydroperoxide 15 mM), and different buffer concentrations (buffer 1, potassium phosphate 50 mM pH 7.0 + EDTA 1 mM +...

Lactobacillus plantarum AJ2 isolated from naturally fermented sausage and its effects on the technological properties of Milano-type salami Ciênc. Tecnol. Aliment.
Sawitzki,Maristela Cortez; Fiorentini,Ângela Maria; Cunha Junior,Anildo; Bertol,Teresinha Marisa; Sant'Anna,Ernani Sebastião.
L. plantarum, strain AJ2, was isolated from naturally fermented sausage manufactured in the Southern region of Brazil and inoculated in Milano-type salami. The lactic culture exhibited the ability of growing in the product, decreasing pH in the first seven days of fermentation/maturation and the residual levels of nitrite and nitrate, as well as peroxide and TBARS values. The inoculated sausage had the highest intensity for brightness and red color, but did not present a difference in chemical composition and fatty acid composition, compared to the control.

Phytogenic additive as an alternative to growth promoters in broiler chickens Ciência Rural
Scheuermann,Gerson Neudí; Cunha Junior,Anildo; Cypriano,Lucas; Gabbi,Alexandre Mossate.
This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P>0.05) treatment effect on feed conversion ratio. No treatment differences (P>0.05) on carcass yield and composition was observed. There...
