随着蛋鸡养殖规模的扩大,在生产中加强节能减排的研究和探索愈发重要。这不仅是节约成本、减少浪费、提高经济效益的最佳选择,也是减少环境污染必需要做的选择。同时“双碳”目标也要求蛋鸡养殖业的升级转型,集约化、规模化最终取代小规模、高污染的蛋鸡养殖模式,节能减排的高质量蛋鸡生产方式是蛋鸡养殖业可持续发展的保障,也是蛋鸡养殖业发展的必然。本文主要综述现阶段蛋鸡生产节能减排的研究进展,以期为蛋鸡节能减排的高质量生产提供借鉴,推动蛋鸡养殖业的可持续发展。 相似文献

铝工业自从问世以来,发展十分迅速,目前铝产量已经位于有色金属之首。我国氧化铝生产过程中,总体情况为高能耗,高污染,低产量。在国家节能减排的大环境下,节能减排势在必行。而蒸发工序是氧化铝生产过程中主要的耗能环节,因此研究蒸发工序节能降耗技术具有重要意义。 相似文献

Antimicrobial usage (AMU) has been described to be high in pig production. Although farmers are aware of the high usage, little is known about intervention to improve the situation. This study evaluated the extent to which AMU could be reduced in pig production by the optimization of herd management, biosecurity status, vaccination strategy, anthelmintic therapy and advice on prudent AMU. Furthermore, the effects of these interventions on the herd production results were explored. This intervention study was conducted on 61 Flemish pig herds and included three visits per herd. During the initial visit, information was gathered on herd management, biosecurity status (quantified by means of the Biocheck.UGent? risk‐based scoring system), vaccination strategy, anthelmintic therapy and AMU. This info was then translated into a herd‐specific action plan which was discussed with the farmer and herd veterinarian/other advisors during the second visit. In the final herd visit (±8 months later), comparable data were obtained to evaluate the progress. Overall, a significant improvement of 2.4 points external and 7 points internal biosecurity on the herds was obtained, combined with additional vaccination, anthelmintic therapy and prudent AMU. This was accompanied by a significant reduction in the AMU with a decrease of 52% for the pigs from birth till slaughter and 32% for breeding animals, based on treatment incidences (TIs) and included an important reduction in the use of critically important antimicrobials. More importantly, the increased biosecurity levels and decreased AMU were combined with significantly improved technical results such as the number of weaned piglets per sow per year (+1.1), daily weight gain (+5.9 g/day) and mortality in the finisher period (?0.6%). Guided interventions as a team effort of farmer and herd veterinarian/other advisors have shown to be a promising method in the reduction of AMU in pig production. 相似文献
