This study aimed to investigate the effects of three strains of probiotics, these being Lactobacillus rhamnosus GG, Bifidobacterium animalis subsp. Lactis BB-12 and Saccharomyces boulardii CNCM I-745, on the body weight, animal performances and blood parameters of rabbits (male and female) of the ITELV2006 strain. The supplementation of the feed of the rabbits with the three probiotic strains allowed observing positive effects on most of the biochemical and haematological parameters investigated during a period of 60 days (30 days of supplementation and 30 days without treatment). Further, there was a significant improvement in the body weight of the rabbits at the end of the experiment. The effect of the three probiotics investigated in this trial was found to be related to the sex of the rabbits and to the intake period (duration). Ultimately, these findings raise the possibility of using probiotics to investigate in an in-depth and specific manner based on fixed factors such as the strain, the gender and age of the animals, the main underlying mechanisms and effects, which would allow achieving optimal and adapted health benefits and sustainable production. In the context of animal production, it is worth investigating in a targeted study the effect of the three strains on muscle growth and development and finding evidence of the possible consequences on meat quality traits of the rabbits supplemented with probiotics.

This study aimed first to develop an experimental model of obesity and metabolic syndrome over 14 weeks using a diet called “cafeteria”, which is a high-fat diet, to evaluate its consequences on the biochemical and morphometric parameters in ITELV2006 strain rabbits. Second, the trial aimed to evaluate the effect of two strains of probiotics, these being Bifidobacterium animalis subsp. lactis BB-12^® and Lactobacillus plantarum 299v^®, on the obesity and MetS induced during the first experiment. Overall, the results of the “cafeteria” diet demonstrated significant changes in numerous biochemical and morphometric parameters, reproducing obesity and the main clinical manifestations of the metabolic syndrome in humans. The administration of the two probiotic strains demonstrated an impact on certain parameters of obesity and induced MetS. This study makes it possible to conclude that probiotics could be useful in the treatment of obesity and metabolic syndrome of rabbits, but in a dependent manner. Furthermore, this study evidenced the importance of selecting specific probiotic strains and dosages to achieve desirable results on rabbits or other species.

Camel meat is considered as good source of nutrition, its taste and texture are similar to that of cattle and has an amino acid content ten times higher than that of the latter. Moreover, its consumption is very low and the manufacture and marketing of cameline meat products are very neglected. The objective of this work is to promote camel’s meat and the derived products from it. Thus, the industry sector should launch and invest in the production of large ranges of camel meat, in order to meet consumer demands.

Among the mammals domesticated by humans for their needs, the dromedary, which is a versatile animal, is used for the production of milk, meat, wool and skin, as well as for sports, tourism and transport. However, knowledge about the breeding and feeding of this animal is limited. The objective of this work is to synthesize previous works on the breeding and feeding of camels in Algeria. The results show that the main farming systems are transhumant, sedentary and nomadic. In addition, the diet of the dromedary is based on different types of Saharan routes and constitutes the main element upon which an extensive camel breeding system is based. Thus, for a better valorization of this species, further studies on the diet and breeding methods of camels are recommended.

In many countries around the world, camel milk is a healthy food used to treat many health issues including diabetes. Thus, it has been demonstrated from several studies in vivo that the consumption of camel milk either fresh or fermented could have a positive effect on certain diseases and metabolic disorders such as hypercholesterolemia and hypertension. Furthermore, lactic cultures from camel milk have also been tested for the action of some active proteins or probiotic and have shown encouraging results. The objective of this work is to synthesize the data related to the benefits of camel milk and its effect on the regulation of glycemia. More in-depth studies should be carried out on humans, in order to confirm the effect of camel milk on glycemia.
