开展生长猪动物实验，验证一试验假设：不讨论葵花籽副产品生产于哪个地区，其总能、粗蛋白、酸水解粗脂肪、总膳食纤维、不溶性膳食纤维、可溶性膳食纤维的全肠道表观消化率和代谢能没有显著差异。
从美国（两个样品）、乌克兰（两个样品）、匈牙利和意大利收集六个葵花籽粕（SFM）样品，以及一个来自美国的膨胀葵花籽粕（SFE）样品。 配制了以玉米为基础的对照日粮和 7 种含有玉米和向日葵副产品的日粮。将来自四个不同断奶组的 64 头去势公猪（初重 31.5 ± 3.2 kg）分配到 8 种日粮，使用随机完全区组设计。 猪单独圈养在代谢笼中，并提供三倍于维持能量需要的饲料。 在适应日粮7 天后收集粪便和尿液 4 天。
结果表明，与葵花籽粕相比，膨胀葵花籽粕中总能和粗蛋白的全肠道表观消化率较小（P < 0.05），但酸水解粗脂肪的表观消化率更高（P < 0.05）。葵花籽粕和膨胀葵花籽粕之间的代谢能没有显著差异。 来自乌克兰和匈牙利的葵花籽粕中总能和总膳食纤维的消化率大于（P < 0.05）来自美国或意大利的葵花籽粕。美国2号样本中酸水解粗脂肪的消化率高于其它样品（P < 0.05），其它样品之间的酸水解粗脂肪的消化率没有显著差异。 美国 1号样和来自意大利的样中可溶性膳食纤维的消化率低于其他样品（P < 0.05）。乌克兰 2号葵花籽粕样品的总膳食纤维消化率（P < 0.05）大于两个美国样本。 来自乌克兰的葵花籽粕样本和来自匈牙利的样品中的代谢能高于（P < 0.05）美国 1 号样和来自意大利的葵花籽粕。
总之，葵花籽粕和膨胀葵花籽粕中总能和养分的全肠道表观消化率有差异，但葵花籽粕中总膳食纤维和代谢能的消化率与可溶性膳食纤维的值没有差异。 在葵花籽粕样品中总能、酸水解粗脂肪、粗蛋白的消化率变化相对较小，但代谢能和总膳食纤维的消化率不同。
Metabolizable energy and apparent total tract digestibility of energy and nutrients differ among samples of sunflower meal and sunflower expellers fed to growing pigs
An experiment was conducted to test the hypothesis that there are no differences among samples of sunflower coproducts in apparent total tract digestibility (ATTD) of gross energy (GE), crude protein (CP), and acid hydrolyzed ether extract (AEE), total dietary fiber (TDF), insoluble dietary fiber, soluble dietary fiber (SDF), or in metabolizable energy (ME) regardless of where the ingredient was produced. Six samples of sunflower meal (SFM) were obtained from the United States (two samples), Ukraine (two samples), Hungary, and Italy. A sample of sunflower expellers (SFE) from the United States was also used. A corn-based control diet and 7 diets containing corn and each sample of sunflower coproducts were formulated. Sixty-four barrows (initial weight?=?31.5?±?3.2 kg) were allotted to 8 diets using a randomized complete block design with four blocks of pigs from four different weaning groups. Pigs were housed individually in metabolism crates and feed was provided at three times energy requirement for maintenance. Feces and urine were collected for four days after seven days of adaptation to diets. Results indicated that the ATTD of GE and CP in SFE was less (P?<?0.05) than in SFM, but ATTD of AEE in SFE was greater (P?<?0.05) compared with SFM. No difference in ME between SFM and SFE was observed. The ATTD of GE and TDF in SFM from Ukraine and Hungary was greater (P?<?0.05) than in SFM from the United States or Italy. The ATTD of AEE did not differ among SFM samples with the exception that ATTD of AEE in the U.S. 2 sample was greater (P?<?0.05) than in the other samples. The ATTD of SDF was less (P?<?0.05) in the U.S. 1 sample and the sample from Italy than in the other samples. The ATTD of TDF was greater in the Ukraine 2 sample of SFM (P?<?0.05) than in the two U.S. samples. The ME in the SFM samples from Ukraine and in the SFM from Hungary was greater (P?<?0.05) than in the U.S. 1 sample and the SFM from Italy. In conclusion, ATTD of GE and nutrients differed between SFM and SFE, but the ATTD of TDF and the ME in SFM was not different from value for SFE. Among SFM samples, relatively small variations in ATTD of GE, AEE, and CP were observed, but ME and digestibility of TDF varied.
