When you are involved to increase your Day Old Duck quality, many ways are possible : hatchery management, vitamins & microelements in breeders, & sometimes additives. In this huge world of additives, Probiotics have a specific target = change the microbiota to a healthy one ! Many studies in all the species proved that is possible, and, a better microbiota means a better health.
Several families of Pre/Probiotics exist on the market, one is the live microorganisms (bacterium alone or a mixture). We can speak sometimes to a “new flora”. The idea is to provide good bacteria inside the feed, the water or on the eggshell/ducklings (at the hatchery level). Those additives should decrease the health challenges, so, less use of antibiotics.
Inside feed &/or water, we want to limit the development of undesirable bacteria by many ways = competition for nutrients, place on the gut wall, less energy spend to fight against bad bacteria … This way is very efficient when birds are young, but less & less efficient with age. Why ? Because when a duck is adult, the gut is fully mature, to change is microbiota, you should provide the “new flora” all the time. Otherwise, you will come back to the previous flora in a short time (except if this new flora is coming from “Duck bacteria strain”, in this case, this flora could multiply alone by natural colonization).
On the eggshell, at the hatchery, we want to avoid development of bad bacteria from unfertile eggs or eggs with a dead embryo/duckling. The timing (at which day of incubation) & the flora used are crucial to reach a good effect (this way is more complicated than inside feed). On the ducklings, they will ingest this flora to make a good first colonization of their gut (same effect than inside feed or water but earlier).
We use and test those additives at different levels to provide the best duckling quality everywhere. Currently, they are used, even in very good conditions. By this way, they could increase the performance of growth, laying rate… Never forget that use a live good bacterium in the same time to an antibiotic treatment is useless, because you will kill it ! However, use this live bacterium just after an antibiotic treatment will be very useful to create a new & good microbiota (whatever the age). Keep in mind also that should work well in young duck, however, I think no live bacteria from duck are available on the market (mostly they come from broiler strains). In addition, like all additives, you must try in your local conditions to check if it’s working well or not for your farms !
Kwa sababu ya ubora wa bidhaa, kuna njia nyingi za kuongeza ubora wa bidhaa: kuunganisha vitamini na viungo vya micro katika uzalishaji, na wakati mwingine kuongeza. Katika ulimwengu huu mkubwa wa nyongeza, Probiotics kuwa na lengo maalum = kubadilisha microbiota kwa moja afya! Uchunguzi wa kila aina ya viumbe unaonyesha kwamba kuna uwezekano wa kuwa na viumbe wengi zaidi, na kwamba kuwa na viumbe wengi zaidi kunamaanisha kuwa na afya bora. Kuna aina kadhaa za Prebiotics, moja ni viumbe hai (bacteria peke yake au mchanganyiko). Tunaweza kuzungumza wakati mwingine kwa <unk>mimea mpya<unk>. Wazo ni kutoa bakteria nzuri ndani ya chakula, maji au juu ya shell ya yai au ducklings (katika ngazi ya hatchery). Viongezeo hivyo vinapaswa kupunguza changamoto za afya, kwa hivyo, matumizi machache ya viuavijasumu. Katika chakula na maji, tunataka kupunguza maendeleo ya bakteria zisizohitajika kwa njia nyingi: ushindani kwa virutubisho, nafasi kwenye ukuta wa matumbo, matumizi ya nishati kidogo kupambana na bakteria mbaya, njia hii ni bora wakati ndege ni vijana, lakini chini na chini ya ufanisi na umri. Kwa nini? Kwa sababu wakati bata ni mtu mzima, matumbo ni kukomaa kikamilifu, kubadilisha ni microbiota, unapaswa kutoa <unk>mimea mpya<unk> wakati wote. Vinginevyo, utarudi kwenye mimea ya awali kwa muda mfupi (bila shaka ikiwa mimea hii mpya inatokana na <unk>Duck bakteria strain<unk>, katika kesi hii, mimea hii inaweza kuzidisha peke yake kwa ukoloni wa asili). Katika shell ya yai, katika hatchery, tunataka kuepuka maendeleo ya bakteria mbaya kutoka mayai unfertile au mayai na kiinitete wafu. Wakati (siku gani ya incubation) na mimea kutumika ni muhimu kufikia athari nzuri (njia hii ni ngumu zaidi kuliko ndani ya kulisha). Katika ducklings, wao ingest mimea hii kufanya colonization nzuri ya kwanza ya matumbo yao (athari sawa na ndani ya chakula au maji lakini mapema). Sisi kutumia na mtihani wale nyongeza katika ngazi tofauti kutoa ubora bora duckling kila mahali. Kwa sasa, zinatumiwa, hata katika hali nzuri sana. Kwa njia hii, wangeweza kuongeza utendaji wa ukuaji, kiwango cha kuweka... Kamwe usisahau kwamba kutumia bakteria hai nzuri katika wakati huo huo kwa matibabu ya antibiotic ni bure, kwa sababu utaiua! Hata hivyo, kutumia bakteria hii hai tu baada ya matibabu ya antibiotic itakuwa muhimu sana kuunda microbiota mpya na nzuri (kwa umri wowote). Kwa upande mwingine, kwa sababu ya kuonekana kwa viungo vya bakteria katika viungo vya duck, hakuna bakteria yoyote ya duck inayoweza kupatikana kwenye soko (kwa kawaida hutoka kwa aina ya broiler). Aidha, kama nyongeza zote, lazima kujaribu katika hali yako ya ndani kuangalia kama ni kazi vizuri au si kwa ajili ya mashamba yako!
