“…According to the report of Kocher, et al [78], the improved performance was observed due to the inclusion of enzyme cocktail (pectinase, amylase and protease) in corn-SBM-based diets for chicks. Cowieson, et al [79] indicated that exogenous xylanase, amylase, protease, and phytase (Avizyme) can be used to maintain the performance of birds fed on a nutritionally rich feeding diet.…”

Article HistoryThe anaerobic probiotic technology (ZAD) is a patented technique. The products are in two forms either liquid or powder. The powder products are coated so it can handle the pressure and the temperature of the extruders. They are fed as follows; 10 gm/head /day for large animals or 1 kg/ tone of fed (for ZADO). In case of Liquid (ZAD); it is fed 10 ml/head/day for large animals and 1.5 ml liter for poultry and rabbits. It decreases the aflatoxins less than 11% by inclusion rate of 7% of ZAD in 7 hours. They are helping the animals to cope with heat stress. Their ability to decrease the cholesterol and triglycerides are noticed by 21 and 19%, respectively. The birds and animal immunity is elevated too. Animal performances are improved in animals fed either form. Milk production increased in dairy cattle (1.5 kg/animal/day) and dairy buffaloes (1kg/head/day). The same trend was recorded for meat production in cattle, buffaloes, and sheep (220, 180 and 90 gm/head/day, respectively as an average daily gain). For poultry, it helped in decreasing the fattening period by 5 days. In fish, the final weight increased by 18%. For rabbits, it increased the milk production, decreased the mortality rate, increased the average daily gain, and improved all over physiological aspects of rabbits.Contribution/Originality: This study documents the impact of probiotics on the growth performances and nutritional aspects of dairy animals, poultry, rabbit, fish, and beef. The primary contribution of this review article is to analyze the influence of anaerobic probiotic technology on the performances and other physiological aspects of ruminant and non-ruminant animals.

“…Cowieson et al (2006), working with reduction in the level of dietary energy and addition of enzymatic complex (xylanase + protease + amylase + phytase) in diets for broilers observed intake values of digestible fractions (dry matter, nitrogen, energy) greater than or similar to those resulting from supply of diets formulated with adequate nutritional levels without inclusion of enzyme.…”

“…The values of apparent metabolizable energy and apparent metabolizable energy corrected for nitrogen retention determined with 80-week-old laying hens could enable formulations with inclusion of xylanase to provide superior performance compared with those birds fed diets nutritionally adequate without enzyme supplementation. However, information about the digestion and nutritional value of diets with the exogenous enzymes supplementation are important for nutritionists, once they probably enable low-cost formulations and may reduce the risk of having unbalanced nutrients (Cowieson et al, 2006).…”

-The objective of this study was to evaluate the effect of the supplementation of xylanase in diets with reduced energy level on the apparent metabolizable energy corrected for nitrogen, determined with laying hens at 14, 36, 60 and 80 weeks of age. Four digestibility trials were conducted, using 80 Hy-line W36 laying hens aged 14, 36, 60 and 80 weeks of age. Birds were distributed in a completely randomized design in 2 × 2 factorial arrangement (energy level × inclusion of xylanase), totaling four treatments with 10 replicates of two birds each. Treatments were: positive control (balanced diet for their age); positive control + xylanase; negative control (diet with reduction of 100 kcal/kg in the level of metabolizable energy); and negative control + xylanase. Xylanase, produced by microorganism Trichoderma reesei, was added to the diets at 100 g/t (16,000 BXU/kg) for diets fed at 14 weeks and 75 g/t for diets of 36, 60 and 80 weeks (12,000 BXU/kg). The data obtained were subjected to analysis of variance at 5% probability. Supplementation of xylanase promoted higher values for AME (apparent metabolizable energy) and AME n (apparent metabolizable energy corrected for nitrogen) determined with 80-week-old laying hens, subjected to diet with energy level according to the nutritional requirements for their age. Supplementation of xylanase increases the matabolizability coefficient of the dietary crude protein and improves the nitrogen retention of laying hens at 14 weeks. In addition, xylanase associated with adequate levels of dietary energy promotes higher values for AME and AME n determined with laying hens at 80 weeks of age.

“…Nevertheless, the digestibility of CP and gross energy were slightly increased on the HM diet, but not the lower MIL diets. Cowieson et al (2006) suggested that the digestibility of nutrients by broilers fed on maize-soybean meal-based diets can be improved by the use of a combination of xylanase, amylase, protease and phytase. The nature of the diet (among others, particle size, pellet or mash) may influence nutrient digestibility and regulate response to exogenous enzymes.…”

________________________________________________________________________________ AbstractA total of 210 day-old male Cobb broiler chickens were randomly assigned to six treatments in a 3 × 2 factorial design. The treatments consisted of three levels of maize: 250 g/kg (LM), 500 g/kg (MM) and 750 g/kg diet (HM) and two levels of enzymes: plus enzyme and no enzyme. Each treatment was replicated five times, with seven birds per replicate. Chickens were reared in multi-tiered brooder cages to 21 days of age in a climate-controlled room. Feed and water were provided ad libitum. Over the feeding period (21 d), there was an increase in feed intake as maize inclusion level (MIL) increased in diets, while supplementation with microbial enzyme improved feed intake only in the MM diet. There was an improvement in live weight (LW) in chickens with increased MIL in their diets. The microbial enzyme supplement also improved LW, but only on the MM diet. The feed conversion ratio (FCR) was improved with increase in MIL in diets, but the enzyme supplements had no effect on FCR up to day 21. At day 21 there was an increase in relative weight of the small intestine with an increase in MIL, but this was not affected by enzyme supplementation. The weight of the liver increased with increase in MIL and enzyme supplementation. At day 21 the pH of the digesta in the gizzard declined with an increase in MIL in diets. In general, there was no significant effect of MIL or enzyme supplementation on pancreatic tissue protein content, chymotrypsin amidase activity and ileal digestibility of protein, gross energy and starch at 21 days of age. The population of Clostridium perfringens decreased significantly with increase in MIL, but other microbial species were unaffected. The present findings suggest that maize could be included at much higher levels than is currently done without detrimental effects on productivity. Exogenous enzymes also resulted in a significant increase in some of these variables. ________________________________________________________________________________
