The present investigation aimed to explore the impact of dietary graded levels of two types of probiotic bacteria (BT and BB) on growth, carcass traits, meat quality, and bacteriology of growing Japanese quail reared under cage system. One thousand and three hundred sixty Japanese quail day-old chicks randomly divided into ten groups (eight replicates each). Birds were fed a basal diet (control, T1) and the basal diet plus 0.05, 0.075, 0.10 and 0.125% BT (T2, T3, T4 and T5, respectively), 0.10% BB (T6) and the same previous doses of BT plus 0.05% BB (T7, T8, T9 and T10, respectively). Results showed a significant (P<0.001) increase in final body weight and weight gain (WG) due to probiotics supplementation (except T2 for WG). Both feed intake (FI) and feed conversion ratio did not differ during the overall experimental period (1-42 days of age, DOA) except FI that was reduced in T2 and increased in T5 and T9 groups. All carcass traits studied were significantly (P < 0.01) affected by probiotics, and the combination between BT and BB in group T8 increased all studied parameters as compared with the other treatment groups. The quail meat color of redness a* and L* values, thiobarbituric (TBA) content, cooking loss, proteolysis, and total coliform (TC) were decreased (P<0.001) by probiotics treatment. In general, supplementing BT, BB, or their combination to the basal diet delayed the proliferation of pathogenic bacteria in the diet and intestine. Using BT and BB as feed supplements enhanced growth performance and meat quality of quails as well as diminished pathogenic bacteria proliferation in their diet and intestine. According to our results, we can recommend the application of T5, T8 to T10 levels for the best performance, carcass traits, and meat quality of growing quails.

This study investigated two kinds of probiotic bacteria (Bacillus toyonensis, B1 and Bifidobacterium bifidum, B2) on laying Japanese quail’s performance, egg quality, fertility and hatchability, blood biochemical characteristics and microbiological parameters. A total of 270 mature quails (180 females and 90 males) were distributed into ten groups in a completely randomized design at eight weeks of age. The experimental groups were as follows: T1: basal diet only (control); T2-T5, basal diet plus 0.05, 0.075, 0.10 and 0.125% B1, respectively; T6: basal diet plus 0.10% B2; T7-T10: basal diet plus 0.05, 0.075, 0.10 and 0.125% B1 plus 0.05% B2, respectively. Results revealed that egg number (EN) and egg weight (EW) were gradually increased (P<0.01) as the levels of both probiotic types increased. The feed conversion ratio (FCR) was significantly (P<0.05) better within the total experimental period (8-20 weeks) due to B1 alone or/with B2 supplementation. Values of yolk percentage (Y%) were statistically (P<0.01) higher only at 8-20 weeks of age and T10 recorded the highest value. By increasing the level of probiotics, fertility and hatchability percentages (F% and H%) were gradually increased (P<0.01 and P<0.05). Creatinine (CR) level was statistically reduced in birds fed T4 diet. Also, urea-N and aspartate aminotransferase (AST) levels were reduced in treated birds. The opposite was found regarding alkaline phosphatase (ALP). Conclusively, using B1 and B2 enhanced the productive performance, some egg quality traits, fertility and hatchability, digestive enzyme activities, and reduced the harmful bacteria in the gut of laying Japanese quail. Our findings could recommend to apply T4 (basal diet + 0.10 % B1), T6 (basal diet + 0.10% B2) and T9 (basal diet + 0.10% B1 + 0.05% B2) levels for the best results.
Growth Performance of Broiler Quails Fed with Enriched Probiotic Feed
2018
Probiotic can help in stimulating the growth and development of immune organs, improve level of immunoglobulin and antibody as well as improve immunity in animal. This present study was carried out to determine the effect of feed enriched with probiotics on the growth performance and hepatosomatic index of broiler quails. A total of 240 quails were divided into four groups with three replicates per group. Each treatments group has a different feeding treatment in which treatment 1 (T0) act as a control with no probiotic added, treatment 2 (T1) with 0.05% probiotic added, treatment 3 (T2) with 0.20 % probiotic added and treatment 4 (T3) with 0.35 % probiotic added, respectively. Probiotic was mixed in the feed of quails starting from day 14 until day 42 and the quails were fed ad-libitum twice per day. The results showed that there was a significant different between treatment group and control in weight gain (p<0.05), average daily gain (ADG), feed conversion ratio (FCR) and feed...
Effect of Feed Supplement and Probiotics on Growth Performance of Japanese Quails
The study was conducted on 120 day-old Japanese quail chicks under deep litter system which were randomly divided into four group viz., T 1 , T 2 , T 3 and T 4 of thirty birds each. Group T 1 , T 2 and T 3 were given feed supplement, probiotic and their combination, respectively along with basal diet and the group T 4 was kept as control. At 6 week age, higher (P<0.05) body weight was observed in group T 3 (147.33±2.57 g) and T 1 (147.00±4.58 g) in comparison to group T 2 (127.00±4.24 g) and T 4 (125.27±4.28). The average FCR was better in group T 3 (3.24±0.44) followed by T 1 (3.26±0.45), T 2 (3.68±0.58) and T 4 (3.81±0.60) during 0-6 weeks age. The present finding suggested that the feed supplement, probiotic and their combination might be utilized in Japanese quail farming under deep litter system.
Effect of supplementation of multi-species probiotic on production performance of Japanese quail
An experiment was conducted to study the effect of multi-species probiotic on production performance of Japanese Quails. Three hundred Japanese quail day old chicks were randomly divided into a control and three treatment groups with three replicates of 25 each and reared in cages for six weeks. The basal diets were supplemented with multi-species probiotic to control, T1, T2, and T3 diets @ 0, 0.005, 0.01, and 0.02 % level respectively. The parameters such as biweekly body weight, FCR, and livability were recorded and analyzed. The groups supplemented with multi-species probiotic at 0.01, and 0.02 % level had resulted in significantly (P < 0.01) higher mean body weight (185.62±2.51g and195.05±2.12g), better FCR (2.84±0.03 and 2.69±0.04) respectively than other groups. It can be concluded that the supplementation of multi-species probiotic in diet at 0.01, and 0.02% levels were found to be beneficial for higher production performance of Japanese quail.
