Nutritive value of Masson Pine pollen (Pinus massoniana) in comparison to wheat bran and effects on stool characteristics in a pig model
The effect of pollen of Chinese Masson Pine (Pinus massoniana) on stool weight, faecal characteristics and nutrient digestibility was investigated in a total of 18 balance measurements. 9 young pigs (40–60 kg of BW) were subdivided in a randomized latin square to three treatments offered either a control diet, this diet added by 3.5 % of Masson Pine pollen or 3.5 % wheat bran. Masson Pine pollen increased (p < 0.05) daily bulk volume, water content of stool and daily faecal nitrogen, triacyglycerol and cholesterol excretion. Daily faecal bile acid excretion was increased (p < 0.05) compared to the wheat bran group. Digestibility of dry matter, crude protein and crude lipids was decreased (p < 0.05) and daily faecal excretion of different bacterial species was increased (p < 0.05) in pollen fed animals. In conclusion, Masson Pine pollen may be a useful additive to elevate fibre supply in men.
