“…It seems that the main factors contributing to the increased degradation of phytate in liquid fermented diets are the acidification of fermentation media due to the proliferation of lactogenic bacteria population and the time of fermentation. It has been demonstrated that microbial phytase added to fermented high moisture maize remains active for a considerable time, thus maintaining its capacity to release phytate P (Niven et al, 2007). As shown in Figure 1, the mean pH value of the fermented diets was approximately 4.4, which was 0.9 units lower than the optimum for Peniophora lycii phytase (5.3).…”

A digestibility experiment using six ileally cannulated growing gilts (initial BW 31.6 kg) was carried out to study the effect of microbial phytase and diet form on apparent ileal and total tract digestibilities of dry matter (DM), nitrogen (N), phosphorus (P), calcium (Ca) and energy and on apparent ileal digestibility of amino acids. The basal P-deficient diet was fed either dry or mixed with water (feed:water ratio 1:2.5) and fermented in a laboratory setup. The enzyme was added to the dry diet at four levels (0, 1 000, 1 500 and 3 000 U/kg) and to the liquid fermented diet at two levels (0 and 1 000 U/kg) using a 6 × 6 Latin square design. The supplementation of microbial phytase to the basal diets significantly (P < 0.05) improved ileal and total tract digestibility of P and tended to improve the digestibility of Ca. Phytase supplementation at 3 000 U/kg to the dry diet improved ileal and total tract P digestibility by approximately 30 and 60%, respectively. A similar effect was found in the liquid fermented diet supplemented with phytase at 1 000 U/kg. As a result of improved P digestibility, faecal P excretion was reduced by 20-40%. There was no significant effect of phytase addition or diet fermentation on the digestibility of DM, N, energy or amino acids. The response in amino acid digestibility to phytase calculated with acid insoluble ash as a marker was slightly higher than that calculated with Cr 2 O 3 .

“…During the air-proofed storage, the moist maize primarily undergoes lactic acid fermentation (Taylor and Kung, 2002). Because this process leads to phytate degradation in seeds, P utilisation in monogastrics might be improved (Niven et al, 2007;Humer et al, 2013;Kraler et al, 2014), which may subsequently reduce the feed costs to the farmer and decrease P pollution. We based our calculations for the ATTD of P in the different maize conserves from a previous study (Humer et al, 2013) in which a higher ATTD of P was found when the maize was fermented.…”

“…On the other hand, in a review by Souffrant (2001) it was concluded that the effect of dietary fibre on digestibility is variable due to the high variability in the physico/chemical characteristics of this nutrient. The higher CTTAD of P with the CS diet can be attributable to the fact that in the grain fraction of silage the phytic P is degraded and the mineral can therefore be better utilised, than no silage products, by monogastrics (Niven et al 2007). A higher P digestibility with high moisture maize meal in comparison with dried maize meal was also reported in fattening pigs by Humer et al (2013).…”

Two experiments were conducted to investigate the inclusion of high cut whole plant corn silage (HCCS) in diets for finishing heavy pigs on digestibility, metabolic utilisation, growth performance and slaughter traits. A control diet (CTR, containing maize meal, barley meal, extracted soybean meal and wheat bran, 550, 250, 90 and 80 g/kg DM, respectively) was compared with diet (CS) containing 200 g/kg DM of HCCS. The HCCS replaced wheat bran and part of maize meal in the CTR diet. In the first experiment, eight barrows were used in a two periods cross over design with periods of 21 d, included 7 d of total collection and three cycles of 24 h each in a respiratory chamber. In the second experiment, 28 barrows were divided into pairs on the basis of BW, kept in 14 pens and fed with the experimental diets until slaughter. Lower DM, OM, CP and energy total tract apparent digestibility was measured for the CS diet. Overall P retention as percentage of P intake was higher for CS diet, while N retention was similar for the two diets. Pigs fed CS tended to have a lower retained energy and the estimated NE of maize silage was 8.47 MJ/kg DM. Pigs fed the CS diets had a lower daily gain, a lower BW at slaughter and a reduction in the weight of back fat. The inclusion of HCCS increased the size of the stomach, the aNDFom concentration of stomach content and reduced the incidence of follicular gastritis. ARTICLE HISTORY
