This study focused on a sample of 48 sheep, representing about 15% of the total number of animals, in the UCPA Gnadil in the Beja region of northern Tunisia. Ewes were milked twice daily by a mechanical pot machine. The average of milk yield during a 175-day milking period was 133 ± 43 l after a lactation phase that lasted an average of 56 days (± 6.6). At the end of lactation, exactly at the 25th and 29th weeks of lactation, the qualitative analyzes of the milk essentially revealed that the average values of the fat, protein, lactose and total dry extract were respectively 8, 5, 6.0, 4.6 and 19.9%. The results of the CMT test recorded the occurrence of some cases of subclinical mastitis of the order of 3%, while the average CCI increased from 463400 cells / ml to reach 788100 cells / ml at the end of lactation.

L'étude est basée sur la capture des oiseaux à l'aide de filets, de nid-trappes ou bien de pièges à appât. Vingt oiseaux appartenant à l’espèce Ciconia ciconia ont été capturés, L’examen de ces oiseaux au laboratoire a montré l’absence d'endoparasites et d'hémo-parasites. Seuls les ectoparasites: les poux (Ciconiphilus zebra et Ciconiphilus quadripustulatus (Burmeister, 1838)) et les tiques de la famille Argasidae ont été enregistrés. Les résultats ont montré que les poux (Ciconiphilus quadripustulatus) sont les plus abondantes. Elles représentent 87,5 % de l’effectif total, suivies par les poux (Colpocéphalum zebra) avec une prévalence de 75% et les tiques du genre Argas avec 62,5%.

Our study area is the entire region of Biskra (Algeria). We used an extensive database of 21 503 date producers distributed in 33 municipalities, to reveal the regularities present in our region. The analysis shows that the distribution of tree planting density is heterogeneous over a very wide spectrum. After a statistical investigation by an analysis of variance followed by a test of less significant differences resulting in a classification of the municipal communes, a zoning is derived in order to depict the differential of date tree density over the totality of the region. This differential is explained by two region-specific factors: the presence of irrigation water sources and joint-products crops.

The study focused on the Ghardaïa region through two areas Metlili and Zelfana, both renowned for camel breeding par excellence. Of the 293 registered camel drivers, 56 were approached as well as 08 owners of specialized farms through semi-structured interviews. Following field investigations, three types of camel breeding systems are to be considered ; whether they embody a system on a course or in (temporary) stabling, the fundamental traits of each are highlighted at a time when the emergence of the specialized camel "dairy" system begins to take shape.
