“…Dès 1995, des nouveaux programmes de recherche ont été élaborés en vue de la caractérisation phénotypique et génétique de la chèvre locale. Ces travaux ont permis une meilleure caractérisation des performances de la chèvre locale (Najari, 2005 ;Gaddour, 2005 ;Najari et al, 2007a ;b ;c ;Gaddour et al, 2007a ;b ;c ;Gaddour et al, 2008a ;b ;c ;Gaddour et al, 2009a ;b ;c ).…”

After 40 years, the first results of the proposed crossing of absorption have been widely transferred at farms in the region. Most herds of goats oasis region were more or less affected by the introduction of goats genotypes. At farm level, the crossing was implemented without technical restrictions in order to generate a genetic mix in the different modes of production. Therefore, we conducted a survey to nearly 85 goat farmers delegation Mareth, where the cross was adopted in different rearing systems. The results show that the conduct is not sufficiently controlled, even in intensive, to enjoy the benefits of crossing. The conduct of breeding and the renewal does not consider the specific genotypes, such as seasonality and sexual risks of inbreeding. Some genetic requirements, such as the slaughter of male F1, are little known and respected by farmers thus hindering the optimization of available genetic resources. The general trend is the use of beef breeds such as improvement in quality races and this is reflected by the increased choice of race Damascus.

Native genetic resource of goats is a pivotal source for meat and milk in southern Tunisia. Feeding is one of the most important activities of goat husbandry. Perceptions on the role of native feed resources for growth and carcass characteristics have not been well studied. Therefore, the present study was designed to help understand and to compare the influences of local forage resources (grass hay, dried olive leaves, Stipa tenacissima and oat hay) on growth performance and carcass characteristics of kids. The kids with the age of 4 months (average live bodyweight of 15 ± 58 kg) were selected for the study. The three study groups in the 90-day trial were as follows: Group C, where animals received oat hay only (control), Group OL, where animals received olive leaves (dried) + S. tenacissima and Group GH, where animals received grass hay. A daily allowance of commercially available concentrate (305 g DM/day) was offered to all groups (making about half of the total DM intake). At the end of the experiment, all animals were slaughtered. Statistical analysis showed that total DM intake was lower (P < 0.001) in C group (490.77 g) than the other two groups having similar DM intake (619.22 and 589.28 g for OL and GH, respectively). Average daily gain was comparable for the three groups (38.33, 40.71 g and 39.52, respectively, for C, OL and GH), with similar final liveweights. Cold carcass weight and carcass yield were not affected by diet treatment. Diet had no significant effect on individual organ weights and carcass composition. The use of the local forage resources evaluated in this trial could be used for the local goat population without loss of productivity when they make up about half of the diet along with a concentrate feed.
