Abstract

The present study aimed to characterize the dairy cattle farming systems in semi arid region in western Algeria. A typology of the farms was established following the description of livestock dairy farming practices and the assessment of their contribution to farm efficiency. The enquiry was conducted on 60 dairy farms during 2018-2019 agricultural campaign to determine structural, technical and economic parameters. The Results show a large diversity of farmer?s strategies, particularly in feeding and economic indicators. The statistical analysis has identified 3 groups of farms. The first group contains 12 farms produce average milk yield about 4120 kg and promote use of forages. The participation of concentrates in total dry matter ingestion (DMI) is about 45.3 %, the average costs of milk production is of 37.1 DA/ liter?0.52 ? and charge of food in total production costs in the order of 62.8 %. 32 dairy farms of second group are characterized by average milk yields 3240 kg and the contribution of concentrated foods represents 49.2 % of total DMI. The cost of liter of milk is about 42.7 DA?0.60 ? and food costs in order of 68.7 % of total production costs. The third group contains 16 dairy farms whose illustrates farms with a significant contribution of concentrates in the global feed balance (54.3 % of total DMI). These concentrated foods were poorly converted into milk as recorded yields are the lowest (2010 kg). Production costs of liter milk and the percentage price of food in total cost production were respectively highest (49.4 DA?0.69 ?) and (80.2 %). The results of this typology indicate the diversity of dairy farms systems in semi-arid region in North Africa, which must be taken to ensure the profitability and sustainability of farms identified. The socio-economic factors are behind the genesis of sample farms, the technical feeding and rationing and no diversification of forage calendar make clear the variations in groups of dairy husbandry. To guarantee sustainability development of typological groups, a specific measure, particularly in feeding management, will be applied for different livestock systems identified.

阿尔及利亚西部半干旱地中海地区奶牛场系统的类型评估
本研究旨在描述阿尔及利亚西部半干旱区奶牛养殖系统的特征。根据牲畜奶牛养殖方法的描述和对其对农场效率的贡献的评估,建立了农场的类型学。该调查是在2018-2019年农业运动期间对60个奶牛场进行的,以确定结构、技术和经济参数。结果显示农民的多样性很大?美国战略,特别是在喂养和经济指标方面。统计分析确定了三组农场。第一组包含12个农场,平均产奶量约为4120公斤,并促进了牧草的使用。精料在总干物质摄食量(DMI)中的参与度约为45.3%,平均产奶成本为37.1 DA/ l ?而食品费用占总生产成本的62.8%左右。第二类32个奶牛场的平均产奶量为3240 kg,浓缩食品的贡献占总DMI的49.2%。每升牛奶的成本约为42.7 DA?0.60 ?食品成本占总生产成本的68.7%。第三组包含16个奶牛场,这些奶牛场在全球饲料平衡中具有显著的精料贡献(占总DMI的54.3%)。由于记录的产量最低(2010公斤),这些浓缩食品转化为牛奶的效果很差。升奶的生产成本和食品价格占总生产成本的比例分别最高(49.4 DA?0.69 ?)和(80.2%)。这一类型学的结果表明了北非半干旱地区奶牛场系统的多样性,必须采取措施确保所确定的奶牛场的盈利能力和可持续性。社会经济因素是样本农场起源背后的原因,技术喂养和定量配给以及饲料日历的不多样化表明了奶牛养殖群体的差异。为了保证类型群的可持续发展,将对确定的不同牲畜系统采取具体措施,特别是在饲养管理方面。
