“…Interleukin 8 has been related to the degranulative effects of neutrophils and its gene overexpression has been described when polyphenols are added to rations (Taub et al 1996;Jung et al 2009). Increases in plasma proteins have also been observed when adding an extract rich in phenols to lamb diets (Rivero et al 2012); and, as observed here, these changes were not related to infectious agents or chronic inflammatory processes, confirmed by the albumin and globulin values (Russell and Roussel 2007).…”

An experiment was conducted to evaluate the effect of a polyherbal mixture based on Withania somnifera, Ocimum tenuiflorum, Tinospora cordifolia and Emblica officinalis, on lamb's growth and blood metabolites. Thirty-two lambs (initial body weight BW 25 ± 4.1 kg) were randomly assigned to the treatments which consisted of the polyherbal ImmuPlus at dietary concentrations of 0, 0.1, 0.2 and 0.3% of dry matter (DM) for 60 days. There was a quadratic response to polyherbal in average daily gain (p < 0.01) and feed conversion (p < 0.05). The optimal concentration estimated by regression for maximum ADG was 0.14 ± 0.08% DM of ImmuPlus. Ruminal DM digestibility was not affected but pH was reduced linearly (p < 0.05). Ruminal N-NH3 (p < 0.01) and total VFA concentration showed a quadratic increment (p < 0.05) whereas butyrate proportion was increased linearly (p < 0.05). There was no effect in most blood metabolites related to energy metabolism, but uric acid was linearly reduced (p < 0.01) and bilirubin showed a quadratic decrement (p < 0.05). Mean corpuscular haemoglobin (p < 0.01) increased linearly (p < 0.10), lymphocytes and segmented neutrophils showed a quadratic response (p < 0.01) and platelets showed a linear reduction (linear p < 0.05). The inclusion of ImmuPlus improved the daily gain in finishing lambs and feed efficiency at 0.1% DM without altering blood chemistry and blood biometry.

“…These improvements were reflected in the feed conversion ratios, which improved by 25•7% for EZSB, 13•5% for EZ and 3•2% for SB treatments. The increased feed intake, nutrient digestibility and daily gain with the administration of SB extract and/or enzymes may be related to the positive effects of metabolites contained in the extract (Jiménez-Peralta et al 2011;Rivero et al 2012: Salem et al 2014a, and/or the action exerted by the enzymes (Rivero et al 2012). Researchers have demonstrated that a positive correlation between feeding animals diets supplemented with fibre-degrading enzymes, their performance and modes of action are uncertain (Alsersy et al in press).…”

“…A hypothesis was developed to explain the synergetic effects resulting from the combination of Salix babylonica (SB) extract and direct-fed enzyme on animal performance: optimal doses of secondary metabolic compounds from plant extracts with optimum doses of enzymes may have cumulative effects on animal performance. Rivero et al (2012Rivero et al ( , 2013 tested the effect of administering 30 ml SB extract in combination with 10 g ZADO ® (i.e. an exogenous enzyme cocktail) on the performance of Suffolk lambs.…”

SUMMARYSixteen Suffolk lambs with 29 ± 2·0 kg body weight were housed in individual cages for 60 days and allotted to four treatments in a completely randomized design to determine the effect of administration of Salix babylonica (SB) extract and/or exogenous enzymes (ZADO ® ) on lamb performance. Lambs were fed with 300 g/kg concentrate (160 g crude protein (CP)/kg, 13·4 MJ metabolizable energy (ME)/kg dry matter (DM)) and 700 g/kg maize silage (80 g/kg CP, 11·7 MJ ME/kg DM) as a basal diet (control). Another three treatments were tested; the SB extract was administered at 30 ml/day (SB) and exogenous enzymes ZADO ® (i.e. an exogenous enzyme cocktail in a powder form) directly fed at 10 g/day (EZ), while the last treatment contained ZADO ® at 10 g/day + SB extract at 30 ml/day (EZSB). Lambs of the treatment EZSB had the greatest average daily weight gain (ADG) and feed conversion throughout the period of the experiment. However, during the first 30 days SB was more effective for ADG than EZ and vice versa during the last 30 days of the experiment. Water consumption was greater for SB, followed by EZ and EZSB compared to the control. Intakes of DM and organic matter (OM) were the highest in EZSB followed by EZ, which had the greatest neutral detergent fibre, acid detergent fibre (ADF) and nitrogen (N) intakes. The EZSB treatment had the greatest DM and OM digestibilities compared to the other treatments; however, SB had the greatest ADF digestibility. Combination of EZ and SB had the best N balance. Allantoin, total purine derivatives (PD), allantoin : -creatinine ratio, and PD : creatinine ratio were increased in EZSB compared to the other treatments. However, EZ supplementation increased uric acid concentration, whereas the microbial N (g N/day) and metabolizable protein (g N/day) were increased in EZSB versus the other treatments. It can be concluded that addition of 10 g ZADO ® in combination with S. babylonica extract at 30 ml/day in the diet of lambs increased feed intake, nutrient digestibility and daily gain, with a positive impact on the use of N and microbial protein synthesis.

“…They found that only the combination of Salix babylonica extract and enzyme had a significant effect on meat quality parameters but no significant effects with only the enzyme addition (Cayetano et al, 2013). A study by Rivero et al (2012) reported the effect of Salix babylonica extracts and exogenous enzymes separately and as a combination on haematological parameters in growing lambs where no effect with any treatment observed.

The concept of supplementation of ruminant diets with exogenous enzymes is not new though a considerable research interest on this field has been emerged from 1990s. Availability of wide range of exogenous enzyme products, development of better methods to evaluate enzyme activity, revised knowledge on rumen functions and recent advances of biotechnology which lowers the cost of enzyme production have fuelled the enzyme utilization in ruminant industries. The exogenous enzymes used in ruminant diets can be characterized in to main categories as fibrolytic, amylolytic and proteolytic based on specific substrate on which their enzyme activity can perform. The sources of these exogenous enzymes are mainly four bacterial species, three fungal species and some yeasts. Solid State Fermentation (SSF) and Submerged Fermentation (SmF) are the major methods for enzyme extraction which have combined with several other biotechnological aspects. The enzyme application method can vary in a wide range from applying to forage at harvesting, at ensiling, at feeding and the portion of feed which is mixed with enzyme may also vary from to forage to concentrate to a part of totally mixed rations. Up to date numerous number of researches have been done with ruminants like cattle both dairy and beef, goat, sheep and less with buffalo. The results seems to be inconsistent but positive results on feed intake, nutrient digestibility, growth performance, other production parameters, manure nutrient excretion etc., have been obtained. Therefore more fine-tuned research efforts are highly suggested for the generalization of exogenous enzyme usage in ruminant nutrition.
