The study was conducted in May and June 2017 in fifteen localities of two departments of Trarza in Mauritania. The objective was to characterize Aftout camel population from socio-economic and morpho-metric characteristics. A questionnaire was administered to 25 breeders in the study area. Nine morpho-metric measurements were recorded on 104 camels aged 6 years or above. The study showed that camel keeping is a typical men’s activity. All the investigated breeders were men, among which 68% are more than 45 years age, and 84 % has never attended formal education. 80% of the breeders have practiced camel rearing for more than 20 years. The activity was considered a major one, as it contributes more than 75% of the family income for 76% of the breeders. The average zootechnic performances were 5.28±1.64 l/d, 3.48±1.15 years, 5.04±0.84 years, 1.38±0.58 years and 1.6±0.40 years respectively for milk production, age at reproduction of females, age at reproduction of males, age at weaning and duration of lactation. The studied biometric measurements highlighted a marked variability. Four morpho-zoometric indices were estimated, and the average estimated body weight was 352.41±55.12 kg. Based on the obtained results, Aftout camel was characterized by a large diversity of practices, which may be an asset for identifying and orienting the productive potential of various camel types in Mauritania.","PeriodicalId":321295,"journal":{"name":"Genetics & Biodiversity Journal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133898232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The THI was used as an indicator of the heat stress threshold. A sample of 75 lactating cows was divided into three groups according to THI level. The cows of group 1, with severe stress (THI>78), those of group 2, with light stress (THI 72-78), and those of group 3 in thermal comfort (THI<72). The daily milk production (DMY), the Physico-chemical quality (TB, TP, and EST), and the hygienic quality (total flora FMAT) of raw milk showed a decrease with the increase of the THI threshold. A significant effect (p<0.05) of heat stress is recorded on the Physico-chemical and microbiological parameters of milk. The FMAT count values of raw milk samples were highest for groups 1 and 2, while a low bacterial load was recorded for group 3 (THI<72). Heat stress had a negative impact on the performance of Prim'Holsteins cows. These preliminary results show the severity of the negative impact of heat stress in the littoral region on the production and the physicochemical and hygienic quality of milk and will serve as a useful guide for farmers to adopt actions to mitigate the impact within the barns for the sustainability of livestock.","PeriodicalId":321295,"journal":{"name":"Genetics & Biodiversity Journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125667757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently goat farms are beginning to regain interest in different Tunisian climatic conditions. Goat breeding is distributed throughout the territory, particularly in the mountain areas, natural rangelands and southern oases. The main systems encountered are (i) systems integrated into farms, (ii) livestock systems in mountainous and forest regions, (iii) oasis ecosystems and (iv) transhumant livestock systems. These farming modes are influenced by developments in agricultural systems in general, which change due to socio-economic development and are dependent on the availability of funding through national projects. In North African countries in general, transhumant pastoral systems dominate arid and semi-arid zones and are characterized by the seasonality of food resources, which are tightly influenced by rainfall. Extensive pastoral farming, mixed with sheep in regions with a dry climate and limited water resources, is the most widespread. Goat farming is a form of savings rather than an economic activity. Concerning the majority of Mediterranean countries; the existing farming systems reveal the importance of socio-territorial unity and available natural resources. The classification of goat farming systems is based on the resources used (natural rangelands or crop residues), the intensity of resource use (extensive or intensive), the types of livestock breeders (nomadic or sedentary), or the product generated and it's quality. The dominant systems in the European countries of the northern Mediterranean shore are farms oriented to the production of goat's milk intended for the manufacture of cheeses.","PeriodicalId":321295,"journal":{"name":"Genetics & Biodiversity Journal","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116149121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
