The duration of the evaluation was 6 months. For the trial, 15 Creole hens were taken, and their feeding costs were evaluated with a diet based on commercial concentrate. They were fed 115 grams of feed per bird daily for a period of 3 months; subsequently, 40% (46 grams) of the diet was replaced with house fly larvae (Musca domestica L.) and 60% (69 grams) with commercial concentrate feed. During the trial period, the following production data were recorded: number of eggs collected and average egg weight. As a result of the work, it was estimated that the feeding costs with commercial feed were $4,673 bird\/month and $4,214.7 bird\/month for the diet consisting of 60% commercial feed and 40% fly larvae. According to the economic analysis, fly larvae supplementation increased income by 56.5%.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786206516330\"\u003e\u003ch3\u003eReducing the feed costs of laying hens with house fly larvae supplementation\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786206516330","offer_id":47152909222213,"sku":"9786206516330","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5567a9ee-5157-4294-b25c-13b679ebe373.jpg?v=1758607937","url":"https:\/\/shop.autorenwelt.de\/products\/reducing-feed-costs-of-layer-hens-von-disney-rodriguez-parra-und-liliana-valencia","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
