Two independent studies were conducted to evaluate the effects of a commercially available phytogenic feed additive (essential oils blend and saponins) to reduce ammonia (NH3) emission in finishing swine. In each experiment, 72 barrows and gilts (Exp. 1: 30.7±3.35kg; Exp. 2: 26.2±1.85kg) were used during 110 and 77 d, respectively. In each experiment, pigs were housed in 8 gas-tight sealed chambers under controlled climatic conditions. Each chamber had three pens with a fully slatted floor. Pigs were allotted into 24 pens (3 pigs/pen). Treatments were assigned to the chambers (4 chambers/treatment). Dietary treatments were: 1) Control, and 2) Phytogenics (100g/MT AromexPro, Delacon Biotechnik GmbH). Diets were offered ad libitum and in mash form. Ammonia emissions were measured during the last 14 d of the experimental period of each study. Ammonia emissions were calculated per chamber as the experimental unit. Air NH3 concentration in the chambers was measured by a Photoacoustic Gas Monitor System INNOVA every 13 minutes. The ventilation rate of each chamber was used to calculate the emission rate. Data were analyzed using PROC MIXED of SAS. In Exp. 1, the phytogenics treatment significantly reduced by 19.5% the daily NH3 produced per animal, and by 20% the NH3 emission per kg body weight gained compared with the control treatment (12.94 vs. 16.07 g NH3/animal/day, P < 0.001 and 13.73 vs. 17.23 g NH3/kg BWG, P = 0.011). Similar findings were observed in Exp. 2, the phytogenic treatment significantly reduced by 19.8% the daily NH3 produced per animal and by 21% the NH3 emission per kg BWG compared with the control treatment (14.40 vs. 17.95 g NH3/animal/day, P = 0.01 and 13.58 vs. 17.18 g NH3/kg BWG, P = 0.01). In conclusion, the results suggest that the phytogenic feed additive used in the present studies can be implemented as a nutritional strategy to reduce NH3 emissions in finishing swine.

PSVI-4 植物性饲料添加剂对肥育猪氨排放的影响
进行了两项独立研究以评估市售植物性饲料添加剂(混合精油和皂苷)对减少育肥猪中氨 (NH3) 排放的影响。在每个实验中,72 头手推车和后备母猪(实验 1:30.7±3.35kg;实验 2:26.2±1.85kg)分别在 110 天和 77 天使用。在每个实验中,将猪圈养在 8 个气密密封室中,并在受控的气候条件下进行。每个房间有三个围栏,地板全是板条。猪被分配到 24 个围栏中(3 头猪/围栏)。治疗被分配到室(4室/治疗)。饮食治疗是:1) 对照和 2) Phytogenics (100g/MT AromexPro, Delacon Biotechnik GmbH)。随意提供饮食并以捣碎形式提供。在每项研究的实验期的最后 14 天测量氨排放。每个室的氨排放量作为实验单位进行计算。每 13 分钟通过光声气体监测系统 INNOVA 测量室中的空气 NH3 浓度。每个室的通风率用于计算排放率。使用 SAS 的 PROC MIXED 分析数据。在 Exp。如图 1 所示,与对照处理相比,植物源处理每只动物每天产生的 NH3 显着降低了 19.5%,每增加公斤体重的 NH3 排放量显着降低了 20%(12.94 对 16.07 g NH3/动物/天,P < 0.001 13.73 与 17.23 g NH3/kg BWG,P = 0.011)。在实验中也观察到了类似的发现。如图 2 所示,与对照处理相比,植物源处理每只动物每天产生的 NH3 显着减少了 19.8%,每公斤 BWG 的 NH3 排放量显着减少了 21%(14.40 对 17.95 g NH3/动物/天,P = 0.01 和 13。58 与 17.18 g NH3/kg BWG,P = 0.01)。总之,结果表明,本研究中使用的植物性饲料添加剂可以作为一种营养策略实施,以减少肥育猪的 NH3 排放。
