The primary purpose of this study was 2-fold. First, it was important to investigate the effects of short-term feeding of Lactobacillus species (plantarum, paracasei, and rhamnosus) via water on nitrogen compounds in manure and blood serum. Second, the effects of sunflower seed meal (SFM) on the same compounds were investigated. Components measured were: ammonia (NH3) emissions from manure, and ammonium nitrogen (NH4-N), total Kjeldahl nitrogen (TKN), and total nitrogen (TN) concentrations in the manure. Biological components of serum included NH3, uric acid, blood urea nitrogen, total protein, albumin, and creatine kinase. Probiotics were mixed in chlorinated drinking water at > 23.3 Mil cfu/g product or 3.64 × 106 cfu/L for each Lactobacillus species to produce approximately 70,000,000 cfu/g product or 1.092 × 107 cfu/L in total. Laying hens (65- to 74-wk-old) were randomly assigned to 4 treatments and fed for 4 wk. Diets were a corn-soy based Control, the Control + Probiotics, the Control + 20% SFM + probiotics or the control + 20% SFM. Major effects and interactions were determined for manure and serum measurements at P < 0.05. Probiotics did not significantly affect NH3 emissions, NH4-N, TKN, and TN in manure. SFM significantly reduced NH3 emissions (P < 0.0001), TKN (P < 0.0001), and TN (P < 0.0001) in manure. TKN in manure was significantly decreased across all treatments. All serum measurements remained statistically similar for the major effects of Probiotics and 20% SFM at P < 0.05.

多种乳酸菌和葵花籽粉对产蛋鸡粪中含氮化合物及血清中生物成分的影响

这项研究的主要目的是2倍。首先,重要的是研究通过水短期饲喂乳酸杆菌植物乳杆菌,副干酪乳杆菌鼠李糖杆菌)对粪便和血清中氮化合物的影响。其次,研究了葵花籽粉(SFM)对相同化合物的影响。测得的成分为:粪便中的氨(NH 3)排放,铵态氮(NH 4 -N),凯氏氮(TKN)总和粪肥中的总氮(TN)浓度。血清的生物成分包括NH 3,尿酸,血尿素氮,总蛋白,白蛋白和肌酸激酶。将益生菌以> 23.3 mil cfu / g产品或3.64×10 6 cfu / L的浓度混合到每种乳酸菌中,以产生大约70,000,000 cfu / g产品或1.092×10 7 cfu / L。将产蛋鸡(65至74周龄)随机分配到4种处理中,并饲喂4周。饮食是基于玉米大豆的对照,对照+益生菌,对照+ 20%SFM +益生菌或对照+ 20%SFM。测定粪便和血清的主要影响和相互作用,P <0.05。益生菌不会显着影响NH 3排放,NH 4-N,TKN和TN肥料。SFM显着减少了粪肥中的NH 3排放(P <0.0001),TKN(P <0.0001)和TN(P <0.0001)。在所有处理中,粪便中的TKN均显着降低。益生菌和20%SFM的主要作用在P <0.05时,所有血清测量值在统计学上仍然相似。
