“…It has been reported that doses of tannins higher than 0.5% of diet DM may decrease the rate of nutrient digestion in the rumen (Mueller-Harvey, 2006). In contrast, some studies have reported a non-harmful effect of tannin extract on ruminant intake (Al-Kindi et al, 2016;Santos et al, 2012). In this study, we decided to use a dose of condensed tannins that is approximately ten times lower than the usual doses reported in most studies in the literature to minimize further negative effects, mainly on DMI and ruminal deamination, which are also effects promoted by sodium monensin (Duffield et al, 2012).…”

The objective of this study was to evaluate the performance of Nellore bulls finished in the feedlot and fed high-energy diets containing sodium monensin associated or not with tannins and saponins. Ninety-six Nellore bulls were used with an average initial body weight of 350.6±17.9 kg. The bulls were weight-blocked and randomly allocated to 12 pens, which were considered the experimental units. The treatments were assigned to the pens according to the blocks, as follows: sodium monensin (25 ppm; SM) and sodium monensin (25 ppm) plus tannins (350 ppm) and saponins (3.92 ppm, SM+TS). The bulls received an adaptation diet for the first 19 days, a growing diet from day 20 to day 59, and a finishing diet from day 60 to 98 of the experimental period. The animals were slaughtered after 98 days of study. The addition of tannins and saponins to the diets of feedlot Nellore cattle did not change the dry matter intake, hot carcass weight, and dressing percentage; however, it increased body weight by 2.0% and average daily gain by 5.4% and improved feed conversion by 4.3%. The addition of tannins and saponins to high-concentrate diets containing sodium monensin improves the productive performance of Nellore cattle finished in a feedlot for 98 days.

“…Similar results were also obtained by Doreau et al [53], who studied the effect of linseed lipid on ruminal metabolism and intestinal digestibility in cows and reported no change in protozoal number when cows' diet was supplemented with either rolled flaxseed or a mixture of flax oil and flax meal. Santos et al [54] stated that the inclusion of canola seeds had no effect on the pH, ammonia nitrogen, and VFA values in the rumen. They reported that extruded canola seeds might stimulate the efficiency of microbial protein synthesis and, thus, increase protein availability in the small intestine without compromising the total digestibility of protein.…”

Background and Aim: Dietary supplements play pivotal roles in promoting productive and reproductive performance in ruminant animals. The aims of the present study were to evaluate the effects of extruded flaxseed and Salmate® (Ballard Group, Inc, OH, USA) inclusion in diets on milk yield and composition, ruminal degradation and fermentation, and flow of fluids and digesta in lactating cattle. Materials and Methods: Six rumen-fistulated Holstein lactating cows were distributed to a 6 × 6 design of Latin square (L.S.). The groups were assorted into a control group fed a basal control diet and two treated groups fed diets containing extruded flaxseed (7.0%) or Salmate® (25 g/head/day). The basal control, extruded flaxseed, and Salmate® diets were formulated as isonitrogenous and isoenergetic. Each L.S. period of the group comprised 21 days, including 10 days for adaptation to the diet and 11 days for data sampling and recording. Results: Feed intake did not differ among the control, extruded flaxseed, and Salmate® groups. Milk yield (kg) and protein and fat composition (%) were improved on feeding the extruded flaxseed diet compared with the Salmate® and control diets. Extruded flaxseed or Salmate® diet had no effect on the values of ruminal pH, ammonia, and volatile fatty acids except isobutyrate, which decreased in the Salmate® group. Degradable efficiency and ruminal digestibility were significantly decreased with the inclusion of extruded flaxseed and/or Salmate® in the diets. The extruded flaxseed and Salmate® groups had a greater digesta passage rate than the control group. The extruded flaxseed and control groups had a greater liquid passage rate than the Salmate® group. Conclusion: The inclusion of extruded flaxseed in the diet improved (p < 0.05) milk yield, milk composition, and milk Omega-6: Omega-3 ratio with no changes in ruminal fermentation, notable negative effects on degradable efficiency and ruminal digestibility. Keywords: degradability, flaxseed, passage rate, Salmate® ruminal fermentation.

“…Among the five studies submitted, two cannot be considered since one (Petit et al., ) is an in vitro study and the other (Rosa dos Santos et al., ) lacks to report any performance parameters. The remaining three are not tolerance studies since only one lignosulphonate dose level was introduced and the duration was very short (20 and 21 days in two studies).…”

“…Rosa dos Santos et al. () assessed the effects of feeding extruded versus non‐extruded canola seed, with or without 50,000 mg lignosulphonate/kg on rumen fermentation, nutrient flow to the omasum and degradability of DM and N of each diet. Four multiparous Holstein cows were used in a Latin square design with four 21‐day experimental periods.…”

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of lignosulphonate, when used as a technological additive, functional group: binders. In a previous opinion, the FEEDAP Panel could not conclude on the safety of the additive for target species and for the environment. The applicant provided additional information that was assessed in the current opinion. As regards the safety for the target species, the maximum recommended content of lignosulphonate of 10,000 mg/kg complete feed is considered safe in weaned piglet. A safe concentration of lignosulphonate in feed for salmonids and dairy cows could not be identified. The FEEDAP Panel reiterates also its previous conclusions that ‘10,000 mg lignosulphonate/kg complete feed is safe for chickens for fattening, laying hens and cattle for fattening but a margin of safety cannot be identified. Therefore, this conclusion cannot be extended to all animal species/categories’. Considering the absence of adverse effects confirmed by all the ecotoxicity studies up to very high concentrations, no concerns for the environment are expected from the use of this additive in animal nutrition according the conditions of use. Lignosulphonate is efficacious as pellet binder.
