開展生長豬動物實驗，驗證一試驗假設：不討論葵花籽副產品生產于哪個地區，其總能、粗蛋白、酸水解粗脂肪、總膳食纖維、不溶性膳食纖維、可溶性膳食纖維的全腸道表觀消化率和代謝能沒有顯著差異。
從美國（兩個樣品）、烏克蘭（兩個樣品）、匈牙利和意大利收集六個葵花籽粕（SFM）樣品，以及一個來自美國的膨脹葵花籽粕（SFE）樣品。 配制了以玉米為基礎的對照日糧和 7 種含有玉米和向日葵副產品的日糧。將來自四個不同斷奶組的 64 頭去勢公豬（初重 31.5 ± 3.2 kg）分配到 8 種日糧，使用隨機完全區組設計。 豬單獨圈養在代謝籠中，并提供三倍于維持能量需要的飼料。 在適應日糧7 天后收集糞便和尿液 4 天。
結果表明，與葵花籽粕相比，膨脹葵花籽粕中總能和粗蛋白的全腸道表觀消化率較小（P < 0.05），但酸水解粗脂肪的表觀消化率更高（P < 0.05）。葵花籽粕和膨脹葵花籽粕之間的代謝能沒有顯著差異。 來自烏克蘭和匈牙利的葵花籽粕中總能和總膳食纖維的消化率大于（P < 0.05）來自美國或意大利的葵花籽粕。美國2號樣本中酸水解粗脂肪的消化率高于其它樣品（P < 0.05），其它樣品之間的酸水解粗脂肪的消化率沒有顯著差異。 美國 1號樣和來自意大利的樣中可溶性膳食纖維的消化率低于其他樣品（P < 0.05）。烏克蘭 2號葵花籽粕樣品的總膳食纖維消化率（P < 0.05）大于兩個美國樣本。 來自烏克蘭的葵花籽粕樣本和來自匈牙利的樣品中的代謝能高于（P < 0.05）美國 1 號樣和來自意大利的葵花籽粕。
總之，葵花籽粕和膨脹葵花籽粕中總能和養分的全腸道表觀消化率有差異，但葵花籽粕中總膳食纖維和代謝能的消化率與可溶性膳食纖維的值沒有差異。 在葵花籽粕樣品中總能、酸水解粗脂肪、粗蛋白的消化率變化相對較小，但代謝能和總膳食纖維的消化率不同。
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.
