南县位于湖南省洞庭湖中部,养猪事业发达。1988年初我们在该县进行了多点、多批沼液作添加剂喂猪可行性验证观察试验,收到一定宏观效果。为了更准确地探索沼液喂猪在湖区的饲养应用方法、效益和前景,选定牧鹿湖良种示范猪场,由畜牧师和高级畜牧师组成课题组,配备专职饲养员管理开展系统试验。试验选用长白×大约克二元杂交肥育猪72头,按随机取样分为三组,均用自配混合饲料喂养。选用试验猪自产鲜粪为原料的同一沼气池内发 Nanxian County is located in the central part of Dongting Lake in Hunan Province with a well-developed pig industry. At the beginning of 1988, we carried out multi-point and multiple batches of biogas slurry as additives to pig viability verification observation experiment in this county, and received some macroeconomic results. In order to more accurately explore the application of biogas slurry feeding pigs in the lake area, benefit and prospects, selected Deer Lake demonstration farms, from animal husbandry and senior animal husbandry division task force, equipped with full-time breeder management system experiments. In the experiment, 72 Changbai × Yorkshire hybrid fattening pigs were selected and randomly divided into three groups, all fed with self-made mixed feed. Selection of test pigs produce fresh manure as raw material in the same digester hair
