摘要

Twenty-four male piglets were randomly assigned to four dietary treatments, with increasing Tetraselmis sp. incorporation levels (0%, 5%, 10%, and 15%). Following a 4-day adaptation period to metabolic cages, the animals were used in a 2-week digestibility trial and slaughtered for digestive tract measurements and sampling. The apparent total tract digestibility (ATTD), N balance, small intestine digesta viscosity and histomorphology, and hindgut digesta volatile fatty acid (VFA) profile were determined. Polynomial contrasts were employed to examine linear and quadratic effects of Tetraselmis sp. dietary incorporation. The ATTD of most macronutrients and N retention efficiencies decreased linearly (p < 0.05) with Tetraselmis sp. dietary inclusion. The ileum villi height increased linearly (p < 0.001) and the hindgut VFA concentration increased linearly (p < 0.05) with dietary Tetraselmis sp. inclusion. The ATTD values estimated for Tetraselmis sp. biomass using the regression method were 68.3% ± 3.86 for dry matter (DM), 66.1% ± 5.11 for N, and 61.3% ± 4.28 for gross energy. The values calculated for digestible and metabolizable energy (MJ/kg DM) and digestible crude protein (% DM) for Tetraselmis sp. were 9.0, 8.8, and 18.3, respectively. Tetraselmis sp. biomass had lower ATTD values when compared to protein sources commonly used in swine nutrition.

随机将二十四只雄性小猪随机分配到四种饮食治疗中，而四脑则增加了。掺入水平（0％，5％，10％和15％）。经过为期4天的代谢笼子，将动物用于2周的消化率试验中，并被屠杀进行消化道测量和采样。确定了明显的总道消化率（ATTD），N平衡，小肠消化粘度和组织形态学以及后肠摘要挥发性脂肪酸（VFA）剖面。采用多项式对比来检查四方sp的线性和二次效应。饮食融合。大多数大数营养素和N保留效率的ATT均以四静脉速度线性降低（p <0.05）。饮食纳入。回肠绒毛的高度线性升高（p <0.001），后肠VFA浓度与饮食四翼型sp。线性增加（p <0.05）。包容。估计的四边形SP的ATTD值。使用回归方法的生物质为干物质（DM）为68.3％±3.86，N为66.1％±5.11，总能量为61.3％±4.28。对于可消化和代谢能量（MJ/kg DM）和可消化率的原油（％DM）计算的值分别为9.0、8.8和18.3。Tetraselmis sp。与猪营养中常用的蛋白质源相比，生物质的ATTD值较低。
