The present study was carried out to explore the impacts of dietary supplementation of enzyme mixture with sodium butyrate on the growth performance, carcass traits, blood profile and economic benefit in two breeds of weanling rabbits adapted to survive in Egypt (New Zealand White and Rex). One-hundred and twenty weaned male rabbits (New Zealand White and Rex) of 6 weeks of age and 770.5 ± 20 g body weight were allotted randomly into four groups in a factorial arrangement. The obtained results indicated that there were non-significant differences in all growth performance traits, blood profile and economic parameters due to the breed effect.However, there were significant differences in most of carcass traits due to the breed effect except total giblets and New Zealand White breed showed the highest value of these parameters including dressing % (p < .01), forequarter and loin % (p < .001) and hindquarter % (p < .003) compared with Rex breed counterparts. The effect of the treatment and its interaction with the breed significantly (p < .05) improved body weight gain, feed consumption and carcass traits (percentage of dressing, forequarter, hind quarter and lion). However, final body weight and feed conversion ratio were not significantly influenced. Supplementing a diet with treatment significantly decreased blood triglycerides, cholesterol and the ratio between albumin and globulin (A/G ratio), while increased blood total protein and globulin. Although higher feed cost and total costs in treated groups than control ones in each breed, they showed higher total return and net return. Rex non-treated rabbit breed showed the lowest profitability measures compared with other groups. In conclusion, dietary supplementation of multi-enzyme with sodium butyrate is highly recommended in growing rabbits due to their beneficial effects on the growth performance and profitability.

“…Additionally, the supplementation of cellulolytic enzymes to the diet of rabbits has a pronounced positive influence on the weight gain [38]. Since, the rate of digestion of fibre and starch in young rabbits is limited [33,34,39], the supplementation of enzymes increased the dietary digestion as well as performance of young rabbits on starter diets [33,34,40].…”

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.
“…Lam Phuoc and Jamikorn (2017) found that growth performance and feed efficiency of weaning rabbits were positively affected by dietary probiotic. Chandra et al (2014) attributed the improvement in growth performance in response to feeding the probiotic-supplemented diets to improved nutrient digestibility and absorption in the ileum. Pogány Simonová et al (2015) reported that the administration of Enterococcus faecium CCM7420 strain to the rabbits altered their growth performance; these changes may influence the gut function and improve the nutrient uptake.…”

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), β-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary β-pro (enzymes+probiotics) or a combination of enzymes, organic acids and β-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.
