“…Our results show that chitosan had a tendency to decrease IVDMD; however, this was significantly decreased only in the high forage diet. A reduction of in vitro digestibility for maize silage diet and a different forage-concentrate diet with chitosan (325, 750, and 1500 mg/L of culture fluid) has also been observed previously (3)(4)(5). A slight decrease in the digestibility in sheep given chitosan (136 mg/kg of BW) daily via rumen fistula has also been reported (6).…”

“…Although the negative effects of chitosan on the rumen ciliate protozoa population could be useful, such effects on rumen bacteria, with the consequent decrease in dry matter digestibility, would be harmful. The use of chitosan in ruminant diets influences rumen fermentation processes both in vitro and in vivo (3)(4)(5)(6), and it can also inhibit in vitro rumen biohydrogenation when fat sources are included (7). Rumen ciliate protozoa play an important role in increasing the concentration of conjugated linoleic acid (cis9, trans11C 18:2 ; c9, t11-CLA) and trans-vaccenic acid (trans11C 18:1 ; TVA) in the rumen fluid (8,9), and their alteration by chitosan or by a combination of both additives (i.e.…”

An efficient ecofriendly method for the alkylation reaction of various imines is described by a simple one-pot reaction of aldehydes, amines and alkyl iodides in the presence of AgI nanoparticles in aqueous media. Silver iodide nanoparticles mediated an enhanced rate and facility of reaction and showed high influence in the green synthesis of some amine derivatives. Moreover, this nanoparticle increased the yields of products and decreased the reaction times in all cases. The heterogeneous mediator was fully characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and FT-IR experimental techniques.

“…We observed a linear increase in DM and NDF digestibility with chitosan addition in the rumen without effect on DMI (7% increase from diets Q0 to Q150), probably related to altered ruminal fermentation. However, Goiri et al (2009b) showed in vitro conditions that chitosan lowered NDF digestibility. In a study with sheep, chitosan tended to decrease NDF digestibility but without reducing OM digestibility (Goiri et al, 2010).…”

a b s t r a c tThis study aimed to investigate the effects of chitosan on dry matter intake (DMI), nutrient digestibility, ruminal fermentation, and blood metabolites in Nellore steers. Eight ruminally cannulated Nellore steers (540 ± 28.5 kg of BW) were used in a replicated 4 × 4 Latin square design, with 21-d of experimental periods. The animals were randomly assigned to the following treatments: control (without chitosan addition; Q0), Q50, Q100 and Q150, by dosing 50, 100 and 150 mg/kg BW chitosan, respectively, through the cannula. Although there was no difference on DMI, chitosan addition increased dry matter, neutral detergent fiber, and crude protein apparent total-tract digestibility (P < 0.05). Ruminal pH was not affected, whereas NH 3 N concentration was quadratically affected with chitosan addition (P = 0.01). There were no differences in total volatile fatty acids concentration among treatments. Chitosan had a quadratic effect on propionate and butyrate, whereas acetate molar proportions decreased linearly (P < 0.05). Acetate:propionate ratio decreased with chitosan addition (P < 0.05). Plasma glucose concentration was higher with chitosan addition (P < 0.05); however, total protein, urea, aspartate aminotransferase, and gamma-glutamyl transferase were not affected by chitosan. Addition of chitosan altered ruminal fermentation, improved nutrient digestibility, and did not appear to damage animal health.

“…The antimicrobial activity of chitosan has emerged as one of its most interesting properties (Matsuhashi & Kume, 1997), which has led to evaluation of its use in ruminant nutrition. Benefits observed seem to be caused by changes in ruminal fermentation, in particular by increased propionate proportion (Goiri et al, 2010) and decreased methane production (Goiri et al, 2009), which in turn lead to energetically more efficient fermentation patterns. Such shifts in the fermentation pattern could result in increased plasma glucose concentrations (Sauer et al, 1989) and as a consequence in improved productive performance or improved efficiency (McGuffey et al, 2001).…”

The objective of this study was to evaluate the effects of chitosan (CHI) supplementation on production performance and blood parameters in dairy ewes. Twenty-four multiparous Latxa dairy ewes at d 16 of lactation were divided into two groups of 12 ewes each. Ewes were fed one of two experimental concentrates (0.840 kg dry matter/d), control or supplemented with 1.2% CHI, on a dry matter basis. Ewes also had free access to tall fescue hay, water, and mineral salts. The experimental period lasted for 25 d, of which the first 14 d were for treatment adaptation and the last 11 d for measurements and samplings. Supplementation with CHI decreased total (p=0.043) and fescue (p=0.035) dry matter intake (DMI), but did not affect concentrate DMI. Supplementation with CHI, moreover, increased plasma glucose (p=0.013) and BUN concentrations (p=0.035), but did not affect those of non-esterified fatty acids. Dietary supplementation with CHI, however, did not affect milk yield, 6.5% FCM, milk composition, or BW, but it improved dietary apparent efficiency by increasing the milk yield-to-DMI (p=0.055) and 6.5% FCM-to-DMI (p=0.045) ratios. In conclusion, dietary supplementation of chitosan maintained ewe performance while reducing feed intake and improving dietary apparent efficiency.Additional key words: animal nutrition; Latxa ewe; milk production.
