An experiment was conducted to determine the effects of feeding diets containing 0, 5, 10, and 15% ground raw rapeseed to three replicates of 14 laying hens each. Isocaloric isonitrogenous diets were fed for a 28-day experimental period and performance and egg quality parameters were measured. Egg production was depressed at the two higher levels of rapeseed inclusion but was not affected at the 5% level of inclusion. Haugh unit, albumen height, and shell deformation were not affected significantly (P > 0.05) but egg weight decreased progressively as rapeseed inclusion increased. Feed consumption was significantly depressed (P < 0.05) at the 15% level of rapeseed and slightly reduced at the other levels.

A study was conducted to evaluate the effects of dietary supplementation of phytase B (product of the Aspergillus niger phyB gene expressed in Trichoderma reesei) on feed intake, laying performance, eggshell quality, and on phosphorus and calcium balance in laying hens. Seventy-two, 40 weeks old Hy Line Brown hens were fed for 14 weeks the following four phosphorus-deficient (0.12% nonphytate phosphorus, NPP), maize-soybean meal-based diets: (1) calcium-deficient (2.8% Ca) control diet; (2) diet 1 + phytase B at the activity of 2.5&nbsp;acid phosphatase units (AcPU/kg); (3) control diet (3.8% Ca); (4) diet 3 + phytase B at the activity of 2.5 AcPU/ kg. Each dietary treatment was fed to 18 cages of hens, 1 hen/cage kept in individual cages. Hens fed the NPP- and Ca-deficient diets consumed more feed (P &lt; 0.01) and excreted less calcium (P &lt; 0.01) than those receiving P-deficient diets with the standard calcium level. There were no effects of calcium level on feed utilization, egg mass, egg weight, and eggshell breaking strength. Egg production, although numerically higher in hens fed low Ca diets with no enzyme added, failed to be significantly different due to the low number of hens investigated and therefore the measurement should be considered as preliminary and supplementary. Phytase B increased mean egg weight by about 7% in layers fed the NPP- and Ca-deficient diet (Ca &times; phytase B interaction, P &lt; 0.05), increased shell breaking strength, particularly at the standard calcium level, significantly enhanced amounts of calcium retained by layers and amounts of&nbsp; phosphorus retained by hens fed the Ca-deficient diets. Additionally, phytase B improved Ca retention at both dietary Ca levels and phosphorus retention in hens fed the Ca-deficient diets. Results of the study indicate that the efficacy of phytase B in NPP-deficient diets is strongly influenced by the dietary calcium level and the enzyme may modulate egg weight, eggshell quality, phosphorus and calcium retention in laying hens fed low-NPP, maize-soybean meal-based diets.

The aim of the experiment was to determine how the content of lupin meal in the diet for commercial laying hens would affect the quality of fat in the egg yolk. A total of 210 Isa Brown laying hens was divided into three groups: the control group C (fed a mixture containing only soybean meal as a source of protein) and two experimental groups: EN 50% (fed a mixture containing 50% of soybean meal and 50% of white lupin seed meal, Zulika variety) and EN 100% (fed a mixture containing only white lupin seed meal as a source of protein). The results of the experiment using lupin seed meal in the feed mixture as a 50% and 100% replacement of extracted soybean meal confirmed the positive effect of lupin-based diets on egg yolk fat composition. Although the diets did not affect the fat content of the egg yolk, some other changes in the quality of the egg yolk were demonstrated during laying. These changes in egg yolk fat were characterized by a decrease (P ≤ 0.05) of saturated fatty acids (SFA), an increase (P ≤ 0.05) of monounsaturated fatty acids (MUFA), but only in some of them (C17:1 – heptadecenoic acid; C20:1n9 – eicosenoic acid and C22:1n9 – erucic acid) and, what is important, by a significant (P ≤ 0.05) increase of polyunsaturated fatty acids (PUFA) from the n-6 group (C18:2n6 – linoleic acid and C20:2n-6 – eicosadienoic acid) and n-3 group (C18:3n3 – α-linolenic acid; C20:5n3 – eicosapentaenoid acid and C22:5n3 – docosapentaenoic acid). From these results it is evident that using lupin meal in the feed mixtures for commercial laying hens increases the nutritional value and health benefit of the egg through the improvement of the levels of saturated and unsaturated fatty acids.

Abstrak : Tujuan penelitian ini adalah untuk mengetahui pengaruh  penggunaan bahan pakan fermentasi yang tersusun dari dedak padi, dedak jagung, dan bungkil kedelai dengan ukuran bobot badan awal berbeda terhadap  produksi telur ayam ras petelur.  Penelitian ini dilakukan di Laboratorium Lapangan Peternakan (LLP),  Program Studi Peternakan,  Fakultas Pertanian,  Universitas Syiah Kuala tanggal 13 Februari‒14 April 2017. Penelitian ini menggunakan 48 ekor ayam ras petelur (layer), strain Isa Brown.    Rancangan yang digunakan adalah Rancangan Acak Lengkap Faktorial (RAL  Faktorial) pola  3x2.   Faktor A merupakan perlakuan pemberian pakan fermentasi berbasis dedak padi + dedak jagung + bungkil kedelai  dengan level 0% (A1),  15% (A2), dan 30% (A3).  Faktor B merupakan perlakuan ukuran bobot badan awal ayam  yang terdiri dari bobot badan awal sedang (B1) dan berat (B2).   Tiap kombinasi perlakuan terdiri dari empat  ulangan yang  merupakan unit percobaan  yang masing-masing terdiri dari dua ekor ayam ras petelur.   Hasil penelitian disimpulkan bahwa bahan pakan fermentasi berbasis dedak padi + dedak jagung + bungkil kedelai  dedak padi  dapat digunakan sampai 30% untuk mensubsitusi ransum komersil selama bulan pertama periode produksi telur tanpa berpengaruh buruk terhadap produksi telur (HDP), berat telur, dan massa telur  ayam ras,  baik yang berukuran berat badan awal berat maupun sedang.Effect of Inclusion of Feed FermentationComposed of Rice Bran, Corn Bran, and Soybean Meal on Egg Production of Laying HensAbstrac: The objective of  present study was to determine effect of inclusion of fermentation feed constituted of 40% rice bran + 40% corn bran+ 20% soybean meal as partial substitution of commercial diet  to egg production of  laying hens.   As many as 48 pullets were used in this study.  The study was performed into 3x2 factorial completely randomized design.  The 1th factor was the inclusion of fermentation feed as partial substitution of commercial diets with the level of 0, 15, and 30%, respectively. The 2nd factor was the initial body weights of pullets classified into medium and heavy weight. Replication was an experimental unit consisted of 3 birds. The results of study showed that fermentation feed based on rice bran + corn bran+soybean meal could be used up to 30% to  substitute of commercial diet without adverse effect on egg production  of  laying hens  either  medium  or heavy weight. There was no interaction between fermentation feed and initial body weights of hens.     The objective of  present study was to determine effect of inclusion of fermentation feed constituted of 40% rice bran + 40% corn bran+ 20% soybean meal as partial substitution of commercial diet  to egg production of  laying hens.   As many as 48 pullets were used in this study.  The study was performed into 3x2 factorial completely randomized design.   The 1th factor was the inclusion of fermentation feed as partial substitution of commercial diets with the level of 0, 15, and 30%, respectively.  The 2nd factor was the initial body weights of pullets classified into medium and heavy weight.  Replication was an experimental unit consisted of 3 birds.  The results of study showed that fermentation feed based on rice bran + corn bran+soybean meal could be used up to 30% to  substitute of commercial diet without adverse effect on egg production  of  laying hens  either  medium  or heavy weight.  There was no interaction between fermentation feed and initial body weights of hens.
