“…Laying rate did not differ amongst hens that received the control, Prob-1 and Prob-3 treatments. These findings are consistent with the results of preliminary laying hen trials that have reported that probiotic dietary supplements have either some (Krueger et al, 1977;Miles et al, 1981;Nahashon et al, 1994b;Mohan et al, 1995;Yörük et al, 2004) or no beneficial effects (Cerniglia et al, 1983;Goodling et al, 1987;Nahashon et al, 1994c;1996a,b). Settable egg production followed the same trend as that observed in hen-day egg production rates (Table 7).…”

“…No significant differences in feed consumption between Prob-2 and Prob-3 treatments, and also between Prob-1 and control treatments, were determined (P>0.05). In full agreement with our findings, Balevi et al (2001) have indicated that feed consumption for brown layers fed a probiotic (Protexin)-added diet was 2.69 g lower than that of hens given a control diet, while others have reported that probiotic feeding has no significant effects (Cerniglia et al, 1983;Goodling et al, 1987;Nahashon et al, 1994cNahashon et al, , 1996a. Based on the results of the present and previous studies, the influences of dietary probiotics on feed intake could be said to be variable, but no deleterious effect on performance was observed in this case.…”

“…However, with the exception of two studies (Goodling et al, 1987;Nahashon et al, 1996b), no study has yet shown that probiotic feeding has any detrimental effects on health status and productivity of layer hens.…”

“…The results of some experimental trials with probiotics have been inconsistent, due to variations in the bacterial cultures used, the age and breed of layer hens treated and other factors related to the management of production, such as the ingredients and nutritional composition of diet; husbandry practices, including environmental stress factors; and housing hygiene (Cerniglia et al, 1983;Goodling et al, 1987;Nahashon et al, 1994bNahashon et al, , 1996bYörük et al, 2004).…”

The effect of three probiotic dietary supplements on the laying and reproductive performance of layer hens and broiler breeder hens was investigated. A total of four hundred and eighty, 22-week-old layer hens were given diets containing one of three probiotics (1 g/kg diet for each probiotics) from weeks 22 to 49. Seven hundred and twenty female and sixtyfour male broiler breeders were also subjected to the same additive feeding procedure between 21 and 50 weeks of age. The layer hen and breeder trials were initiated simultaneously and performed in pens located in the same area. Either egg production rate or egg weight was affected by the microbial cultures administered. Body weight and mortality were not affected. Egg production rate, egg weight and egg mass benefited from some of the probiotics, while, overall, the probiotics led to significant improvements in the feed conversion rate of layer hens. All of the probiotic preparations decreased the cracked-to-broken egg ratio, compared to the untreated control group. One of the three probiotic supplements significantly improved the egg production rate and increased the settable egg and chick yield per hen in broiler breeders, whereas, overall, probiotics tended to decrease settable egg weight. Probiotics enhanced hatchability, but no beneficial effects were observed on fertility. Based on these findings, it can be said that the microbial cultures in the probiotic preparations exhibited host-specific and strain-specific differences in their activities as performanceenhancer feed additives, with improvements in some selected performance parameters.

“…Several studies with layers indicated that supplementation of probiotics increases the egg production and feed conversion 5, 8, 9. However, a number of studies have shown that probiotics have no positive effects on layers' performance 10, 11. Variation in the effects of probiotics obtained from various studies has been attributed to the difference in the strains,12 form of bacteria,13 their concentrations in the diet4 and viability in the gastrointestinal tract 10…”

Effect of probiotic (Lactobacillus sporogenes) feeding on egg production and quality, yolk cholesterol and humoral immune response of White Leghorn layer breeders

et al. 2007

The effect of probiotic (Lactobacillus sporogenes) feeding on egg production and quality, yolk cholesterol and humoral immune response of White Leghorn (WL) layer breeders was studied. WL layer breeders (24 weeks) were randomly distributed into three groups of 28 each and were housed in individual California type cages. Considering one bird (individual feeding) as a replicate, 28 such replicates were randomly allotted to one of the three dietary treatments: basal (control) or basal with probiotic supplementation at a rate of 100 or 150 mg kg −1 feed. The probiotic used in the study was a commercial preparation containing L. sporogenes with 6000 million spores g −1 of the product. Dietary supplementation of L. sporogenes at 100 mg (6 × 10 8 spore) kg −1 diet significantly increased egg production and feed efficiency. However, body weight gain, feed intake, egg weight, specific gravity and Haugh unit was not influenced by probiotic feeding. The eggshell breaking strength, shell weight and shell thickness increased significantly by feeding 100 mg probiotic kg −1 diet. The serum concentration of calcium and protein increased, and that of cholesterol decreased by L. sporogenes supplementation. The yolk cholesterol followed the same trend of serum cholesterol. Feeding of L. sporogenes significantly enhanced antibody production. No difference in antibody production could, however, noticed between the levels (100 or 150 mg) of probiotic. It is concluded that feeding of L. sporogenes at 100 mg (6 × 10 8 spore) kg −1 diet significantly enhanced the egg production, shell quality and humoral immune response of WL layer breeders during 25-40 weeks of age.
