“…Similarly, our data are consistent with the results of Baidoo et al (2003) showing no effects of phytase supplementation on lactation sow BW. In agreement with Kemme et al (1997b), Baidoo et al (2003) and Jongbloed et al (2004), litter size and litter performance were not influenced by phytase in either experiment.…”

Nyachoti, C. M., Sands, J. S., Connor, M. L. and Adeola, O. 2006. Effect of supplementing phytase to corn-or wheat-based gestation and lactation diets on nutrient digestibility and sow and litter performance Can. J. Anim. Sci. 86: 501-510. Effect of an Escherichia coli derived, 6-phytase on nutrient digestibility and sow and litter performance were investigated. Six (exp. 1) or eight (exp. 2) sows per diet were randomly assigned to a positive control (PC), a negative control (NC) with reduced non-phytate phosphorus (P), NC + 500 FTU kg -1 , or NC + 1000 FTU kg -1 diet from day 60 of gestation to day 22 postpartum. Diets in exps. 1 and 2 were based on corn and wheat, respectively. Energy, N, calcium (Ca), and P digestibilities were determined between days 73 to 77 (Period 1), 104 to 106 (Period 2) of pregnancy, and days 16 to 20 postpartum. Sow and litter performance were monitored. During gestation, phytase at 500 FUT kg -1 did not affect nutrient digestibility in exp. 1 but improved (P < 0.05) DE and digestibilities of DM, energy, N, and P in exp. 2. Increasing phytase to 1000 FTU kg -1 reduced (P < 0.05) digestibilities of energy and N (exp. 1). In both experiments, digestibilities of N, Ca, and P were higher (P < 0.05) in period 2 than period 1. During lactation, supplementing the NC diet with 500 FTU kg -1 only improved (P < 0.05) DE and Ca and P digestibility in exp. 1 and DE and digestible P in exp. 2. Compared with NC, P digestibility and digestible P were higher (P < 0.05) in the NC + 1000 FTU kg -1 diet in both experiments. Sow and piglet performance was unaffected by diet in both experiments. In conclusion, P digestibility was greater between days 104 and 106 of gestation than between days 73 and 77 of gestation and phytase improved P digestibility during lactation but this effect was not consistent during gestation in both experiments.Key words: Digestibility, phytase, phosphorus, sows Nyachoti, C.

Can. J. Anim. Sci. 86: 501-510. Les auteurs se sont intéressés à l'incidence d'une 6-phytase issue de Escherichia coli sur la digestibilité des éléments nutritifs et sur la performance des truies et de leur portée. Six (première expéri-ence) ou huit (deuxième expérience) truies par ration ont été réparties au hasard entre une ration témoin positive (TP), une ration témoin négative (TN) à concentration réduite de phosphore sans phytate (P), la ration TN enrichie de 500 FTU par kg ou la ration TN enrichie de 1 000 FTU par kg, du 60 e jour de gestation au 22 e suivant la mise bas. Les rations de la première et de la deuxième expérience étaient respectivement à base de maïs et de blé. Les auteurs ont déterminé la digestibilité de l'énergie, du N, du calcium (Ca) et du P entre le 73 e et le 77 e jour de gestation (période 1), entre le 104 e et 106...

“…In the present investigations, piglets from the sows receiving the phytase preparation reached higher body weights on day 21 of life as well as at weaning. Similarly, beneficial productive effects of microbial phytase in sow nutrition were reported by Jongbloed et al (2004), who examined the addition of microbial phytase to sow diets in the presence of formic acid. Dietary microbial phytase added to the mixtures without monocalcium phosphate appeared more effective in the diets with lower native phytase activity.…”

“…This fact is probably associated with a higher content of nutritive fibre in the sow pregnancy diets resulting in the decreased availability of minerals. According to Jongbloed et al (2004), sows utilize up to 0.77-0.83 g P ..…”

“…The results of some experiments have shown, however, analogically with trials on growing pigs, a beneficial effect of this enzyme on the digestibility of some nutrients and on the performance of these animals (Kemme et al, 1997;Jongbloed et al, 2004). It should be stressed that in almost all of the experiments on sows, the effect of phytase additive was examined when typical maize-soyabean meal diets, poor in intrinsic phytase, were fed (Hill et al, 2008).…”

The influence of intrinsic phytase and a microbial phytase additive on reproductive traits of sows, the composition of colostrum and milk, and on piglet rearing indices was studied. The two trials differed in the kind of grains used in the diets to give them lower (420-440 PU kg -1 , Trial 1) or higher (1000-1150 PU kg -1 , Trial 2) levels of intrinsic phytase. There were 3 feeding groups (34-35 animals in Trial 1 and 25 in Trial 2) in each experiment. In both trials, group 1 received the basic diet enriched with dicalcium phosphate, group 2, the basic diet without this additive (NC), and group 3, the basic diet supplemented with 500 PU kg -1 microbial phytase. A higher number of liveborn piglets in group 3 in comparison with group 2 in Trial 2 was noted. Also, the body weight of piglets was significantly higher in groups 1 and 3 in comparison with the NC group. The microbial phytase supplement increased the concentration of zn and Cu in colostrum and of zn in sow milk, regardless of native phytase activity.

“…No duodeno o ácido fítico é alcalinizado através de excreções dos sulcos pancreáticos e forma quelatos com minerais e aminoácidos formando a molécula de fitato. Os animais monogástricos como os suínos não sintetizam a enzima fitase, sendo assim, a única maneira de se aproveitar o P e outros nutrientes presentes nos cereais é pelo uso de dietas suplementadas com fitase (JONGBLOED et al, 2013). Neste contexto, para se conhecer o potencial de metabolização do P proveniente da dieta no metabolismo de suínos avaliouse as rotas de excreção do P. As excreções endógenas e urinárias se constituem entre as principais portas de saídas para a excreção do excesso de P, sendo a rota endógena a mais importante.…”
