This method improves chick health without relying on antibiotics, which are increasingly banned due to the rise of antibiotic-resistant bacteria \u2013 a threat to human and animal health.<\/p>\n<p>In her latest study, Amalaradjou wanted to look at the hatching stage itself.<\/p>\n<p>\u201cWe never looked at the in-between window of the actual hatching process so in this study we decided to focus on that,\u201d Amalaradjou says.<\/p>\n<p>This is especially relevant as there has recently been a drop in hatchability, defined as how many chicks successfully hatch from the group of eggs put into an incubator. Scientists do not yet know what could be responsible for this drop.<\/p>\n<p>Amalaradjou observed that when the eggs were sprayed with probiotics, there was an approximately 5% increase in hatchability. The hatchlings were also healthier and more active.<\/p>\n<p>Amalaradjou and her team scored the chicks according to qualitative criteria used by the industry. These criteria include how quickly a chick can stand up after being put on its back; if its naval is fully sealed; if its eyes are open and active; having well-formed legs; inflammation in the hock joint, which the chick uses to crack its egg open; and if it has ingested too much of the egg yolk before hatching.<\/p>\n<p>\u201cThey were all scoring very well,\u201d Amalaradjou says. \u201cThere was a significant difference in the quality of the chicks from the probiotic group compared to the control.\u201d<\/p>\n<p>Following this study, Amalaradjou and her group will simulate the transportation process to see how chicks from eggs treated with the probiotic spray fare.<\/p>\n<p>After they hatch, chicks raised for broiler production are soon transferred to a farm where they grow out. This transfer is often across long distances and the chicks must endure it without food.<\/p>\n<p>\u201cThe hatching process by itself is very stressful,\u201d Amalaradjou says. \u201cThey have to use up all their energy to hatch out and then they have no feed for 48 to 72 hours.\u201d<\/p>\n<p>If the chicks are weak when they hatch, there\u2019s a high chance they will die during or shortly after the transfer.<\/p>\n<p>Amalaradjou hypothesizes that the probiotic spray will give them a leg up in surviving this stressful event as these chicks have proven to be healthier than those in the control group in every other stage.<\/p>\n<p>Amalaradjou will also look at how these chicks grow after transport.<\/p>\n<p>\u201cWe want to figure out if the improvement we see actually translates into reduced mortality of the birds,\u201d Amalaradjou says. \u201cAnd then we want to see what happens to them when they grow out \u2013 do they make more muscle, more meat? That\u2019s the next step because at the end of the day it\u2019s how much meat the birds can make in the case of broiler chickens.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p><em>This work relates to CAHNR\u2019s Strategic Vision area focused on\u00a0<\/em><a href=\"https:\/\/cahnr.uconn.edu\/strategic-vision\/\"><em>Ensuring a Vibrant and Sustainable Agricultural Industry and Food Supply.<\/em><\/a><\/p>\n<p><em>Follow\u00a0<\/em><a href=\"https:\/\/linktr.ee\/uconncahnr_social\"><em>UConn CAHNR<\/em><\/a><em> on social media.<\/em><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This method improves chick health for broiler production without relying on antibiotics, a positive step for human and animal health<\/p>\n","protected":false},"author":127,"featured_media":215686,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_crdt_document":"","wds_primary_category":0,"wds_primary_series":0,"wds_primary_attribution":0,"footnotes":""},"categories":[2298,2224,2235],"tags":[],"magazine-issues":[],"coauthors":[2140],"class_list":["post-215616","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-animal-science","category-cahnr","category-today-homepage"],"pp_statuses_selecting_workflow":false,"pp_workflow_action":"current","pp_status_selection":"publish","acf":[],"publishpress_future_action":{"enabled":false,"date":"2026-04-29 05:33:23","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/215616","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/users\/127"}],"replies":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/comments?post=215616"}],"version-history":[{"count":4,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/215616\/revisions"}],"predecessor-version":[{"id":215701,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/215616\/revisions\/215701"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media\/215686"}],"wp:attachment":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media?parent=215616"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/categories?post=215616"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/tags?post=215616"},{"taxonomy":"magazine-issue","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/magazine-issues?post=215616"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/coauthors?post=215616"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
