Two experiments were conducted to study the effect of feeding raw or treated common vetch seeds (V) on BW, feed intake (FI), egg production (EP), feed conversion (FC), egg weight (EW), shell thickness (ST), yolk color score (YC), and Haugh unit score (HU) of Single Comb White Leghorn hens for 56 d. In Experiment 1, diets contained 0, 7.5, 15, and 22.5% raw V. Compared with the control, the 22.5% V diet decreased (P < .05) BW, FI, and EP. In Experiment 2, intact or ground (G) V were either soaked (S) in water (1:5) for 24 h or autoclaved (A) at 103.5 x 10(3) Pa for 8 h, and then dried (D) at 55 C for 24 h. Eight diets were used, a corn soybean (control) and seven others, each containing 25% V, previously subjected to the forementioned treatments as follows: untreated V (UV), SDV, GSDV, ADV, GADV, SADV, and GSADV. Compared with the control, the UV diet decreased (P < .05) FI (75 vs 98 g) and EP (47.3 vs 88.7%), increased FC (1.99 vs 1.4 kg feed per dozen eggs), and induced BW loss (-63 vs 49 g). Soaking intact V improved (P < .05) FI (85 g) and EP (69%). Remaining treatments resulted in further improvement. Hens fed all V diets produced eggs with HU score 13 points better than that of the control (P < .05). In both experiments, EW, YC, and ST were not different among treatments. Results indicated that autoclaved V at 25% level was not detrimental to layers' performance.
进行了两项试验，研究给单冠白来航蛋鸡饲喂生的或经过处理的普通巢菜种子（V）56天对其体重（BW）、采食量（FI）、产蛋量（EP）、饲料转化率（FC）、蛋重（EW）、蛋壳厚度（ST）、蛋黄颜色评分（YC）和哈夫单位评分（HU）的影响。在试验1中，日粮中分别含有0、7.5%、15%和22.5%的生V。与对照组相比，22.5% V日粮使BW、FI和EP降低（P < 0.05）。在试验2中，将完整的或粉碎的（G）V在水（1:5）中浸泡（S）24小时，或在103.5×10³ Pa压力下高压灭菌（A）8小时，然后在55℃下干燥（D）24小时。使用了8种日粮，一种玉米 - 大豆日粮（对照组）和其他7种日粮，每种日粮含有25%的V，且V先前经过如下所述的处理：未处理的V（UV）、浸泡干燥V（SDV）、粉碎浸泡干燥V（GSDV）、高压灭菌干燥V（ADV）、粉碎高压灭菌干燥V（GADV）、浸泡高压灭菌干燥V（SADV）和粉碎浸泡高压灭菌干燥V（GSADV）。与对照组相比，UV日粮使FI（75 vs 98克）和EP（47.3% vs 88.7%）降低（P < 0.05），使FC提高（每打鸡蛋消耗1.99 vs 1.4千克饲料），并导致BW下降（-63 vs 49克）。浸泡完整的V使FI（85克）和EP（69%）提高（P < 0.05）。其余处理使情况进一步改善。采食所有含V日粮的母鸡所产鸡蛋的HU评分比对照组高13分（P < 0.05）。在两项试验中，各处理间的EW、YC和ST没有差异。结果表明，25%水平的高压灭菌V对蛋鸡生产性能无害。
