Résumé: Our study is carried out in three honey-producing regions, Djamoura, M'Chouneche and El-Kantara, using analysis of reject pellets to study the diet of the European Bee-eater Analysis of reject pellets revealed a high species richness in the M'Chouneche (S M’Chouneche = 51 species). The species Apis mellifera accounts for a large percentage (AR% = 70, 65%) of the total prey eaten by European Bee- eaters at El-Kantara. The fairness value (E) is E = 0.77 in Djamoura, with the recorded diversity value is H’= 1.20 bits. In the El-Kantara site the fairness value is less than 0.5, which explains a certain dominance of a prey species (Apis mellifera) in the Bee-eater menu in El-Kantara.

Résumé: We conducted an avian count from November 2017 to October 2019. This qualitative and quantitative study at
the level of an artificial environment, in the case of the palm grove d’El Hadjed in El Ménea, provides an
objective inventory of the birds' diversity. A total of 48 species have been identified by researchers, distributed
among nine orders and 19 families. The order Passeriformes is the most dominant, with 11 families and 36
species, or 75% of the recorded species. As for Muscicapidae, the Sylviidae are the best represented, with 11 and
5 species, respectively. Depending on phenological status, there are17 species of passage visitors (35.42%), 18
breeding species, of which 13 are residents (27.1%), and 5 are migratory species (10.42%). 12 species (25%)
represent the winter visitor birds.
At the national level, executive Fiat Algerian law (N°12-235) protects 8 species, or 16.67%, while Ordinance
(06-05) protects one other species (Peregrine Falcon). Two species have an international status of "near
threatened" (Lanius senator), while one species is classified as "vulnerable" (Streptopelia turtur). Shannon index
values fluctuate between 2.91 bits (2018) and 2.99 bits (2019), and evenness index (E) values fluctuate between
0.56 bits (2018) and 0.62 bits (2019).

Résumé: Recent research in rabbit farming has focused on studying the impact of proper nutrition on rabbits during the growing stage. This is done in a proposal to find an effective strategy to reduce health problems in animals during weaning, while also considering the technical and economic aspects of this type of farming. Our study aims to clarify the effects of different types and quantities of dietary restriction on rabbits and their performance, based on various studies and research that have addressed this topic. Therefore, this research serves as a comprehensive summary of previous studies on dietary restriction in rabbits during the fattening stage. The results of these studies demonstrate the effectiveness of dietary restriction as a strategy, which can be adopted to achieve the desired economic goals of markets and consumers, as well as health-related objectives and overall profitability in rabbit farming projects.

Résumé: In order to study several aspects of the breeding of small sheep at the wilaya of Tizi Ouzou, 60 farms located in the region are the subject of our survey. The majority of breeders surveyed belong to the middle age group, being their main activity. The farms are of the meat type and generally have a small number of animals (less than 40 heads). The diet is based on grazing and sometimes supplementation with concentrates. A certain diversity of sheep breeds should be noted with the predominance of the Ouled Djellal breed as well as crossbred animals. Autumn and spring are the main breeding seasons with the most popular breeding method being semi-intensive and the practice of natural mating. The number of young per year is 2 to 3 lambs per female. Mortalities affect ewes much more often due to respiratory pathologies and lambs at birth from twin litters. Pastures are essentially the sources of food with supplementation depending on the seasons. The livestock buildings are not equipped
