Study of morphometric and reproductive parameters of equine breeds raised in Algeria

This study was conducted on the purebred Arabian horse, Arab-Barb and Barb, present in the
National Stud of Chaouchaoua, Wilaya of Tiaret. The objective of this work is to identify the
morphometric characteristics of the 20 characters (HG) Height at withers, (HC) Croup height,
Substernal height (HSS) Substernal void (VSS) , Head Languor (LTE), Neck languor (LE),
Anterior canal languor (ACL) Posterior canal languor (LCP), Languor of the pastor (LP),
Total languor (TL), Eye to eye distance (DY), Forearm tour (FT), Tower of Geniuses (TG),
Anterior canal tour (TCA), Neck circumference (NC), Chest circumference (CC), Chest width
(CF), Pasturent tour (TPA), on 43 purebred Arabian Barb and Arab Barb horses aged 3 years
and over. Thus to study the following reproductive parameters (gestation duration), (foaling-
return to heat interval) (foaling-Gestation interval) concerns data from three years (2020, 2021
and 2022).
This study showed significant values of quantitative and qualitative characters for individuals
of both sexes in the sample studied. The results obtained confirm the sexual dimorphism
already known in Equines, and also confirm the results already obtained by other researchers.

Pastoral Assessment of Steppe Rangelands in the Northwestern Region of M'sila (Algeria)

In Algeria, steppe rangelands are experiencing significant degradation due to human and livestock pressures. This is evidenced by the decline in plant species with pastoral value, which undermines the productivity of pastoral livestock systems and, consequently, reduces the incomes of rural populations. A study was conducted at seven stations in the northwest of the region of M'sila. This work was undertaken as part of an analysis of floristic richness and an evaluation of pastoral resources in these steppe rangelands during the spring season. The floristic study identified 40 species belonging to 16 families, including 13 perennials and 27 ephemeral species. The managed rangeland was found to be the richest in species diversity compared to other rangelands classified as open.
The evaluation of pastoral resources was conducted using a method based on specific indices and the contribution of each species. The study yielded the following results: Pastoral productivity was higher in the set-aside rangeland compared to the open rangelands at the various stations studied. The animal carrying capacity was approximately 2.28 livestock units (LU) per hectare per season on the managed rangeland. The open rangelands showed clear signs of overexploitation and degradation of these steppe ecosystems.

Study of the factors influencing the success of the reproduction of turtle doves (Streptopelia turtur) in a fruit tree-type agrosystem (El Hodna, Algeria)

The objective of the study is to find and provide answers on the ecology of the reproduction of turtle doves in an artificial agricultural habitat, composed of two orchards, in particular apricot and olive trees. A total of 203 active dove nests were monitored in these artificial agrosystems.
The density of the nests was higher in the apricot orchards 02,61 nest/ha and 02 nest/ha for the olive tree. Breeding success was higher in apricot orchards than in olive trees. The mean clutch size in the two orchards was 01,93±0,01 eggs per nest. Apricot habitat was 1,90±0,03 and olive was 1,96±0,01. Nest abandonment (69,2%, n=45) and predation (16,9%, n=11) were the main causes of failed incubation stages. The breeding success of nests in the two orchards was 62,89%, for apricot and olive were 65,36% and 59,66% respectively. Desertion was the main cause of nest failure with a value of 69,2%, followed by predation with a frequency of 16,9%. Apricot orchards are the preferred breeding habitat of the dove in this region. In both orchards, nest position variables were not a significant predictor of nesting success.

Evaluation des potentialités pastorales des parcours steppiques algériennes cas de M’sila (Algérie)

Les parcours steppiques en Algérie connaissent une importante dégradation à cause de la pression humaine et animale. Cette dégradation se manifeste au niveau de la réduction du couvert végétal et de la disparition d’espèces d’intérêt pastorales, ce qui affecte la productivité des systèmes pastoraux et par conséquence, aggrave le niveau de pauvreté des populations rurales. Les résultats obtenus montrent que la plantation pastorale a un impact positif à travers l'augmentation tant quantitative que qualitative (richesse floristique, recouvrement globale, phytomasse et productivité pastorale) des parcours aménagés (PA) par rapport aux parcours libre non aménagés (PNA). L’étude floristique souligne une diversité floristique avec 51 espèces regroupant 17 vivaces et 34 éphémères. Du point de vue biodiversité, on note la remontée des espèces indicatrice de la dégradation dans le parcours non aménagés suite à l’éradication des espèces palatables. L’étude des attributs vitaux montre une évolution progressive du recouvrement au niveau des parcours aménagés se traduisant par une phytomasse et une productivité pastorale appréciable de l’ordre de 298 kg MS/ha et 121,7 UF/ha respectivement. Cette situation supporte une charge animale de l’ordre de 2,6 ha par unité ovine. Il en ressort que les parcours libres sans aménagement sont surexploités et tendent vers un état de dégradation très sévère du biotope steppique. La restauration et la réhabilitation des parcours par des actions de plantation fourragère pastorale renforcée par des mises en défens représentent l’issue idéale pour cet écosystème fragile.

Contribution à l’étude des stomoxes au niveau d’un élevage bovin laitier

Les mouches d’étables Stomoxys calcitrans sont des mouches souvent négligées et confondues en Algérie par les éleveurs du fait de leur grande ressemblance avec la mouche domestique Musca domestica, En raison de leur importance économique, et l’absence de données sur la biologie et la dynamique des populations, limite à priori la mise en évidence d’un programme de lutte efficace. Notre étude sur les diptère (Stomoxe), été conduite dans la localité de Souk-Ahras , et le suivi de la dynamique par des captures périodiques réalisées chaque 15 jours, et durant une année à l’aide du piège vavoua, nous a permis l’identification d’une seul espèce : Stomoxys calcitrans
