The main objective of this demonstration project was to demonstrate that a combination
\nof protein-rich feeds with phase feeding may give rise to, on the one hand, a
\nhigher use of the total share of home-grown protein feedstuffs and
\non the other hand, a reduction in total protein input and nitrogen excretion in the production of
\nfattening pigs. This may reduce the dependence on soy imports in Flanders
\nbe reduced. Several rations were formulated in this project. In one
\ndemo trial compared different feeding strategies. Both the technical
\npig results were examined as nutrient excretions and digestibility
\nof the feeds. The study also examined the impact of feeds on profitability,
\nenvironmental impact and soybean dependency verified. In addition to the demo test, there is also
\ncollaborated with 5 field companies to also obtain real-world results.<\/p>\n

According to the literature, feed cost, N excretion and dependence on the
\nsoya imports decrease when transitioning from two- to multi-phase feeding. In addition, the
\nzootechnical results and slaughter quality should be comparable at two- and
\nmulti-phase power supply.
\nThe results confirm these assumptions, with the exception of the five-phase feeding.
\nWith the results of the five-phase feeding, one would see a decrease in cost and N excretion
\nexpect compared to the results of three-phase power supply. But in this trial, the
\nfeed cost and N excretion with five-phase feeding slightly higher than with three-phase feeding,
\nbut this can be explained by the specific experimental conditions.
\nThe trial shows that the use of multiphase feeding in combination with alternative
\nprotein sources in the diet of fattening pigs is certainly possible, provided that these
\nalternative protein sources are sufficiently available.
\nApart from some anomalous values at 95 kg and 110 kg, we can say that a
\nSwitching from two-phase power supply to 3 or more phases can help in the
\nreduction in mineral (nitrogen) excretions. For the anomalous values at 95 kg and 110
\nkg there is no logical explanation. The occurrence of abnormal values happens more often
\nsince there is always an influence of specific experimental conditions.
\nIn general, expectations are met on most practice farms. The
\nbiggest expectation of pig farmers was a fall in feed cost price. The
\nHowever, results appear to be highly variable. On some farms, there appeared to be a strong
\ndecrease in feed costs without compromising on animal results. Other
\nfarms, however, showed an increase in feed costs.
\nOn most farms, there is not a big difference in N-excretion and therefore not met
\nto expectations that N excretion will decrease with increasing number of phases. But because the
\nanimals achieve a specific growth curve and feed intake in each round, there can actually be
\nno exact comparison can be carried out.
\nThe results are promising on some farms. But to really form a decision
\nabout the new system and to make a proper comparison, several
\nrounds to be followed up. In addition, the new systems should further
\nbe optimised to the farm situation and the farmer should also be more
\nfamiliarise yourself with the system to get the optimal result
\nPhase feeding in practice is thus certainly feasible and can contribute to further
\nPig farming optimisation.<\/p>","protected":false},"featured_media":2319,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categorie-projecten":[46],"class_list":["post-2316","projecten","type-projecten","status-publish","has-post-thumbnail","hentry","categorie-projecten-varkens"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/projecten\/2316","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/projecten"}],"about":[{"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/types\/projecten"}],"version-history":[{"count":0,"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/projecten\/2316\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/media\/2319"}],"wp:attachment":[{"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/media?parent=2316"}],"wp:term":[{"taxonomy":"categorie-projecten","embeddable":true,"href":"https:\/\/www.pvl-vzw.be\/en\/wp-json\/wp\/v2\/categorie-projecten?post=2316"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
