Ray fish were caught, filleted, and stored in ice. Fillets were analysed for 18
days to determine the chemical, biochemical and physical changes and their relation to the muscle eating quality. ...Trimethylamine (TMA-N), total volatile bases (TVB-N), ATP content and breakdown products,
K value, pH, texture, water-holding capacity (WHC) and colour changes were monitored. At the beginning of the study, the ray fish muscle showed a low concentration of ATP and a high value of inosine 5′-monophosphate (IMP). Regarding to the signs of freshness and deterioration,
K value presented an exponential increase (
r2
=
0.95) with an initial value of 4.7% and a final value of 47.5%. Furthermore, the TBV-N and TMA-N significantly increased (
P
<
0.05) during the storage in ice. As for the physical analysis whereas the texture changed (
P
<
0.05); pH and the WHC were not affected (
P
<
0.05). The overall results of this study indicated that the edible quality of ray fish muscle was maintained during at least 15
days of ice storage.
In the present work, polylactic acid (PLA), elastin and gelatin fibers, containing clindamycin, were prepared to test their potential application as wound dressings. They underwent release studies to ...determine the mechanism of drug release through mathematical models. The fibers have a homogeneous morphology, without pores. The studies of FTIR and thermal analysis corroborate the presence of each of the components in the fibers; the results of the feasibility tests showed encouraging percentages with a viability of 82% after 7 days of direct contact of the HUVEC cells with the membranes. Similarly, cell adhesion assays show the presence of viable and stretched cells on the fibers, the tendency of the cells to position themselves on the fibers and follow this conformation was observed. On the other hand, studies of antimicrobial activity against
S. aureus
show us that in fibers loaded with clindamycin they have inhibition halos greater than 8 mm.
•A probiotic, prebiotic, and their combination was tested in lambs fed high-energy diet.•Probiotic increased apparent N digestion, digestible energy, and ruminal pH.•Prebiotic increased apparent ...digestion of OM, NDF, N, digestible energy, and ruminal pH.•The combination potentiated the positive effects observed for both supplemented alone.
Probiotics (beneficial living microorganisms) and prebiotics (fiber, cell wall material, mannan polysaccharides derived through hydrolysis of yeast cell walls) are feed additives that may have beneficial extra-nutritional pharmaceutical and/or metabolic effects on livestock health and growth performance. Due to differences in modes of action, their combination may have additive effects on digestion and fermentation in ruminants. For this reason, four male lambs (Dorper; 45.1 ± 2.7 kg initial weight) with “T” cannulas in the rumen were used in a 4 × 4 Latin square experiment to evaluate the effects of single or combined supplementation of probiotics and prebiotics on ruminal fermentation and total tract digestion. Dietary treatments consisted of a cracked corn-based basal finishing diet supplemented with: 1) no eubiotics (Control); 2) 3 g of live saccharomyces cerevisiae /lamb/day (2 × 1010 cfu/g, SC), 3) 3 g of mannan oligosaccharide (30 % w/w) plus b-glucans (20 % w/w) /lamb/day (MOS), and 4) combination of 1.5 g/day SC and 1.5 g/day MOS (SCMOS). Compared to controls, SC supplementation tended (P = 0.09) to increase total tract digestion of DM and OM, and increased (P < 0.05) total tract digestion of N, starch, and digestible energy (DE). Compared with Control, MOS increased total tract NDF (7.9 %, P < 0.01) and starch digestion, and tended to improve total tract digestion of (P = 0.09), N (P = 0.07), and DE diet (P = 0.07). Compared to Control, SCMOS increased (P ≤ 0.03) total tract digestion of all fractions evaluated, including a 4.2 % (P < 0.01) increase in DE. Although lambs fed MOS had greater (6.7 %, P = 0.02) NDF digestion than those fed SC, differences in total tract digestion of DM, OM, N, starch and DE diet were not appreciable (P ≥ 0.24). Compared with SC and MOS fed separately, SCMOS increased (P < 0.05) total tract digestion of N and NDF. Supplemental MOS and SCMOS tended (P = 0.09) to promote greater ruminal pH than the Control. Combining supplementation decreased (P ≤ 0.03) the molar proportion of butyrate and ruminal ammonia, consistent with decreased of ruminal concentration of C. aminophilum. Probiotic/prebiotic supplementation of high-energy lamb finishing diets enhances total tract digestion and digestible energy. Reduction hyper-ammonia producing ruminal bacteria with the combination probiotic plus prebiotic may contribute to improved dietary N economy. The combination of probiotics with prebiotics potentiate positive effects on digestion and ruminal fermentation in lambs fed a high-energy diets.
