“…Parallel to the current ndings, Ayyat et al, (1996) suggested that diets supplemented live yeast (Lacto-Sacc) for lactating rabbits increased milk production, litter size, and weight at weaning. Furthermore, Belhassen et al, (2016) showed that the fertility rate and the viability rate of litter at birth of rabbit does were higher in the live yeast (probiotic) group than those with the control diet.…”

This study aimed to investigate the effect of diet supplementation with a symbiotic (SY), bee pollen (BP), honey bee (HB), date palm pollen (DPP) and their mixture (MIX) on female rabbit productive and reproductive performances under desert hot climates. Seventy-two Californian does of 5 months age and average body weight of 3250 ± 78.2g was randomly allotted into six groups. All does were orally received 3 ml distilled water for 10 days before mating and 28 days during pregnancy. Treatments were repeated for four consecutive parities. The first group was served as control (C) given distilled water only, however the second, third, fourth and fifth groups were supplemented with 3ml distilled water containing0.2 ml SY, 200 mg DPP,200 mg BP, 0.2 ml HB/doe per day, respectively. While, the sixth group does were given all previous ingredients (MIX). Sexual receptivity rate, fertility rate, kindling rate, and newborn traits were recorded. Also, maternal feed intake, feed conversion ratio, and digestibility coefficients were recorded. Treatment increased maternal body weight and daily gain with highest values (P < 0.05) in BP, SY, and MIX does. All treatments enhanced feed intake and feed conversion ratio (FCR) compared with control. Number services per conception decreased (P < 0.01), while litter size and weight and survival at birth and weaning increased (P < 0.01) in treated than control does. Treated does produced more milk than control. All digestibility coefficients were improved (P < 0.01) in treated does. In conclusion, supporting rabbit does pre- and during pregnancy with diets supplemented with a mixture of honey bee, date palm pollen, bee pollen, and synbiotic improved the productive and reproductive performances of rabbit does and their offspring.

“…Moreover, Jurgens et al (1997) noted that active dry yeast included in sow diets did not improve sow reproductive performance as measured by number of pigs born, litter birth weight or litter weaning weight. On the contrary, in other studies Maertens et al (1994) and Ayyat et al (1996) observed a significant (P<0.05) improvement in litter size and weight at 21 d and at weaning due to Paciflor ® and to Lacto-Sacc supplementation. Furthermore, Zaleska et al (2015) observed an increase in prolificacy in sheep fed yeast.…”

“…However, studies on the use of yeast as a probiotic in rabbit does are scarce. Indeed, the results of Ayyat et al (1996) suggest that the inclusion of a probiotic (Lacto-Sacc) in diets of lactating rabbit does increased milk production, litter size and weight at weaning. The objective of our study was to evaluate the effects of diet supplemented with live yeast Saccharomyces cerevisiae W o r l d R a b b i t S c i e n c e (Actisaf Sc 47, France) on mortality and reproductive performance of rabbit does and the performance of their progenies over 2 reproductive cycles.…”

A study was conducted to determine the effect of live yeast supplementation in the diet of rabbit does on their mortality and reproductive performance and the performance of their progeny. A total of 52 cross-bred rabbit does (New Zealand×Californian) were divided into 2 groups differing in diet offered during 2 reproductive cycles and containing (group S; n=26) or not (group C; n=26) 1 g of yeast (Actisaf Sc 47, S.I. LESAFFRE, France)/kg of feed. Natural mating was performed 11 d after kindling and kits were weaned at 28 d of age. Body weight of litters was measured at birth, 21 d and at 28 d of age (weaning). Mortality of kits and rabbit does was monitored daily, and fertility of rabbit does and viability rate of kits at birth were also determined. Weight and litter size at birth and at weaning, litter weight gain during lactation and length of gestation were similar between the 2 groups during the 2 cycles. The mortality of does during the experiment was higher in group C than in group S (27 vs. 4%; P<0.05). Fertility rate of rabbits does and viability rate of kits at birth were higher (P<0.05) in rabbits fed with the supplemented diet than those with the control diet during the second lactation. In the first cycle, kit mortality was lower in S group (15.5%) than the C group (24.7%) during the first 21 d (P<0.05). However, no difference was observed during the second lactation. In conclusion, our results suggest that the inclusion of yeast in the diet of rabbit does could trigger positive effects on the fertility and mortality of rabbit does, as well as on the viability rate of kits at birth.

Seventy-two Californian does of 5 months age and average body weight of 3250 ± 78.2 g were randomly allotted into six groups, each of 12 does.

While, the sixth group does were given all previous ingredients (MIX). Sexual receptivity rate, fertility rate, kindling rate, and newborn traits were recorded. Also, maternal feed intake, feed conversion ratio, and digestibility coefficients of nutrients were recorded. Does in all groups were artificially inseminated with 0.5 ml of fresh heterospermic semen of 15 fertile bucks extended in Tris at 806–1006 sperm/ml. Treatment increased maternal body weight and daily gain with highest values (P < 0.05) in BP, SY, and MIX does. All treatments enhanced feed intake and feed conversion ratio (FCR) compared with control. Number services per conception decreased (P < 0.01), while litter size and weight and survival at birth and weaning increased (P < 0.01) in treated than control does. Treated does produced more milk than control. Digestibility coefficients of all nutrients were improved (P < 0.01) in treated does. In conclusion, supporting rabbit does pre- and during pregnancy with diets supplemented with a mixture of honey bee, date palm pollen, bee pollen, and synbiotic improves the productive and reproductive performances of rabbit does and their offspring.
