Effects of Canthaxanthin on Egg Production, Egg Quality, and Egg Yolk Color in Laying Hens

Abstract

<p class="4"><span lang="EN-US">The effects of canthaxanthin (CTX) on egg production, (average daily feed intake) ADFI, egg quality, and yolk color compared with n<a name="_GoBack"></a>atural xanthophylls in feedstuffs in laying hens were studied in a 5-wk trial. A total of 280 36-wk-old ISA Brown layers were divided into the following 7 treatments: T1, negative control (30% corn+20% wheat); T2, diet with 50% corn; T3, diet with 5% DDGS; T4, diet with 10% DDGS; T5, T1+0.011% CTX; T6, T1+0.021% CTX; T7, commercial diet with 40% corn. Although ADFI, and egg quality were not affected by dietary treatments, the egg production was higher (<em>P</em><0.05) in diet supplemented with 0.021% colorant than diet with 50% corn, and diet supplemented 0.011% colorant. Yolk color in layers fed the diet contained 10% DDGS was higher (<em>P</em><0.05) than the layers fed the T1 diet, and the diet with 5% DDGS. Yolk color score was linearly improved (<em>P</em><0.05) when the diet supplemented with 0.011%, and 0.021% CTX. Higher yolk color score was also observed (<em>P</em><0.05) when layers fed commercial diet compared with control diet, and the diet with higher natural xanthophylls. In conclusion, egg production and yolk color were improved when layers fed diet supplemented with colorant.</span><span lang="EN-US"> </span></p> <!--EndFragment--> S style='font-size:10.5pt;mso-bidi-font-size:12.0pt;font-family:"Times New Roman","serif"; mso-fareast-font-family:??;mso-font-kerning:1.0pt;mso-ansi-language:EN-US; mso-fareast-language:PL;mso-bidi-language:AR-SA'>slightly degraded chernozem, formed from loess. The examined inoculants were applied during sowing. The presented results of the studies on the symbiotic nitrogen fixation by leguminous plants indicate that the productivity of pea was positively affected by the application of IUNG (noncommercial) inoculant. On the other hand, it is not recommended to use Nitragine^TM separately, as it inhibits the growth of pea. Plants of the ‘Klif’ variety used the symbiotically fixed nitrogen more effectively and demonstrated higher yield component and better phenotypic parameters.<p> </p

Karakterisasi Mie Mojang (Mocaf-Jagung) Dengan Perbedaan Jenis Dan Konsentrasi Bahan Pengikat

“…Semakin tinggi penambahan bahan pengikat, kesukaan panelis terhadap warna mie mojang semakin besar yaitu semakin berwarna kuning. Kuning telur mengandung pigmen xantofil yang menyebabkan warna kuning atau oranye 28 sehingga semakin tinggi konsentrasi penambahan telur intensitas warna mi mojang semakin terlihat dan panelis lebih menyukai mi mojang dengan penambahan telur dibandingkan gum xanthan atau konjak. Semakin tinggi konsentrasi telur yang ditambahkan rata-rata skor hedonik terhadap warna mi ubi jalar semakin naik 29 .…”

“…Hal ini dikarenakan terdapat kuning telur. Kuning telur mengandung xantofil dan pigmen karotenoid yang menyebabkan warna kuning 28 .…”

“…Nilai chroma tertinggi terdapat pada perlakuan P8 (penambahan telur 5%). Telur mengandung xantofil dan pigmen karotenoid yang menyebabkan warna kuning atau oranye 28 sehingga mi mojang yang dihasilkan lebih berwarna kuning dibandingkan dengan penambahan gum xanthan dan konjak. Didukung oleh 35 , penambahan telur menyebabkan warna menjadi lebih kuning.…”

Production of Pigment Enriched Desi Chicken Eggs by Feeding of Tagetes erecta Petals

“…Recent trend in fortification of poultry products is enrichment with natural antioxidants through herbal feed additives since consumer's preferences for natural organic products in their food are increasing (Cho et al, 2013). In Andaman & Nicobar Islands, backyard poultry eggs meet out more than 60 per cent of rural requirements of rural people for eggs.…”

“…Further, backyard poultry farmers face problems in better hatchability at field level due to lack of cold storage before natural hatching using broody hens. Carotenoid pigments are potent natural antioxidants (Cho et al, 2013). Since the usage of synthetic pigment in the feeding of rural poultry is highly impossible by the rural poultry keepers, natural carotenoid source should be of ideal choice as pigmenting agents for egg yolk.…”
