<div><strong>Background: </strong>Faba bean (<em>Vicia faba</em> L.) is thirst most important grain legume in the world and the first one in Algeria. The chocolate spot disease caused by Botrytis fabae Sard (BF), is the major constraint of this culture in Algeria when caused a destructive damages.<br />
<br />
<strong>Methods:</strong> The aim of this study is to find the sources of resistance for Seven varieties of faba beans (Giza 02, Giza 40, Giza 461, Sakha 02, Sakha 03, Precoce de Seville), by using the detached leaflet inoculation test for resistance to the two isolates from BF represent two different regions of northwest Algeria (Mascara and Relizane).&nbsp;</div>

<div><br />
<strong>Result:</strong> A significant difference (P &lt;0.05) was observed in the reaction of the varieties which manifest themselves by a different reaction vis-&agrave;-vis the isolates of BF. Total sensitivity was observed in the four (4) varieties Giza02, Sakha01, Sakha02 and Sakha03, two (2) varieties (Giza40 and Ziban), are tolerant, while the variety named &lsquo;Precoce de Seville&rsquo; showed significant resistance to both isolates from BF. These results showed a similar pathogenic behavior of two isolates of BF and variability in the level of reactions of the varieties of beans. The variety &lsquo;Precoce de Seville&rsquo; showed promising results to be valued and cultivated in order to reduce the damage caused by this disease and reduce the use of chemicals.</div>

<div>The effect of Moringa oleifera essential oils supplementation on milk quality and fatty acid profile was studied in Sicilo-sarde sheep. Twenty-four Sicilo-Sarde ewes were divided into three homogeneous groups (8 animals per group): the control (C), O-M1 and O-M2 groups. The control group (C) received a basal diet of oats hay with complementation to the reason of 500 g/ewe/day of concentrate feed. While, ewes of the experimental batches (O-M1 and O-M2) received further to the basal diet and concentrate, 0.3 ml and 0.6 ml of Moringa oleifera essential oil (EO), respectively. The performance of the milk has been assigned (P&lt;0.01) by the incorporation of essential oils (EO) of Moringa oleifera and the dose. The Fat content was significantly high (P&lt;0.01) in favor of the group O-M2, while the protein content was statistically comparable (P&gt;0.05) for the three groups. The concentration of urea nitrogen of the milk has been affected by the presence and the dose of EO of Moringa oleifera (P&lt;0.01) in favor of the control group. Milk saturated fatty acids decreases (P&lt;0.01) with the dose of EO, while PUFA, CLA and UFA/SFA were higher for the group (O-M2) (P&lt;0.01). The supplementation of the essential oils of Moringa oleifera has improved milk production and quality of Sicilo-Sarde ewes during lactation period.</div>

<div>Inter simple sequence repeat (ISSR) amplification was used to study the genetic diversity between three populations of the Sicilian-Sardinian dairy sheep breed. This breed is only found in the north of Tunisia (Beja and Bizerte governorates) where the climate is subhumid (&gt; 600 mm / year) and is favorable to large forage production. The studied animals belong to three regions: Gnadil (Beja), Nagachia (Beja) and Fretissa (Bizerte). In total, 153 bands were amplified and all were polymorphic (100%). Within populations, the Nei&rsquo;s gene diversity, the Shannon index and the percentage of polymorphic loci were between 0.08 and 0.16, 0.13 and 0.27 and 30.72% and 77.78% respectively. The coefficient of gene differentiation (Gst) and the gene flow (Nm) between populations varied from 0.12-0.2 and 1.99-3.65. The UPGMA dendrogram, grouping the three studied populations, based on the Nei&rsquo;s standard genetic distances showed that the populations of Nagachia and Fretissa are genetically the closest while the population of Gnadil is the most distant one.</div>
