The experiments were conducted to evaluate the effects of whole wheat on the production performance, egg quality, and nutrient digestibility when supplemented primarily at the expense of corn in ground corn-soybean meal control diets. The experiments utilized Lohmann Brown Classic laying hens from 45 to 53 wk of age. The results were shown that feeding 5, 10, 15, 20, or25% whole wheat in diet had no effect on the production performance and egg quality, whereas 15, 20, and 25% whole wheat in diet decreased the yolk color (based on the Roche color fan score) when compared with layers fed the control diet.Whole wheat level in diet had no effect on dry matter,organic matter digestibility, and apparent metabolizable energy when compared with laying hens fed the control diet. Therefore, whole wheat can be used at levels of up to 25% in laying hen diets without negatively affecting the production performance, but levels over 15% whole wheat decreased the yolk color.

Apparent Metabolizable Energy

This study aimed to evaluate açaí meal in diets for commercial laying hens on apparent nutrient digestibility and apparent metabolizable energy. A total of 72 Hissex White laying hens (52-wks-old) were distributed in a completely randomized design, where treatments consisted of a control diet and an experimental diet (25% açaí meal) with six replicates of six birds each. Data collected were subjected to polynomial regression at 5%. Differences (p < 0.05) were detected in digestibility of all evaluated nutrients. Hens fed diets with 25% açaí meal presented worse (p < 0.05) metabolization and use of energy content. It can be concluded that hens fed diets containing açaí meal presented better use of crude protein, non-fiber carbohydrates and mineral matter. However, there was worse use of dry matter, fiber carbohydrates and ether extract. This result directly affected the energy metabolism of the birds. The inclusion of açaí meal reduced the energy use.

The objective of this study was to evaluate the effects of acid silage meal made of pirarucu waste in diets for commercial laying hens on apparent digestibility and energy metabolism. Seventy-two Hisex White hens with 71 weeks of age were assigned to a completely randomized with two treatments (control diet and diet with 3% pirarucu waste acid silage) with six replicates of six birds each. The ensiled biomass was light brown in color, showing acidified aroma; creamy consistency; 4.38±0.11 pH; 84.16% dry matter; 40.06% crude protein; 26.82% ether extract; 9.31% mineral matter, 65.16 g kg-1 calcium and 22.90 g kg-1 phosphorus. Differences (p > 0.05) were detected in digestibility of crude protein, non-fiber carbohydrates (soluble carbohydrates), etherextract, mineral matter, metabolizable energy and metabolizable energy coefficient. Our results indicate that the acid silage mealmade of pirarucu waste can be included up to 3% in diets for laying hens, showing satisfactory nutrient digestibility and potential to be used as an energy source.

Abstract We aimed to determine the effects of feeding a high-oleic peanut (HOPN) diet to egg-producing laying hens on egg quality, digestibility, and feed conversion. Three isonitrogenous and isocaloric dietary treatments were formulated with 1) Control diet (CON)—a corn-soybean meal conventional diet with 7.8 % added poultry fat, 2) HOPN diet—dietary inclusion of ~20% coarse-ground whole HOPN, and 3) oleic acid (CON-OA) diet—a control diet supplemented with 2.6% oleic fatty acid oil. Ninety-nine 57-wk-old brown Leghorn laying hens were randomly assigned to 33 animals per treatment. Animals were housed individually for 8 wk. Body and feed weights were recorded weekly and feed conversation ratio was calculated. Bi-weekly, shell eggs were analyzed for quality (yolk color, albumen height, and Haugh unit [HU]). Jejunum samples were collected at week 8 for histomorphometric analysis. Analysis of variance was performed on all variables using a general linear mixed model. Laying hens fed the CON-OA diet produced greater number of eggs relative to those fed the HOPN and control diets (P &lt; 0.05). The roche yolk color value was higher (P &lt; 0.001) in eggs from hens fed the HOPN diet. There were no differences in laying hen performance, eggshell color, eggshell strength, eggshell elasticity and egg albumen height, or egg HU, ileal fat digestibility, or villi surface among treatment groups. However, the apparent metabolizable energy (P &lt; 0.01) and ileal protein digestibility (P = 0.02) were greater in laying hens fed the HOPN diet relative to the CON diet. This study suggests that whole unblanched high-oleic peanuts may be an acceptable alternative feed ingredient for laying hens.

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

The effects of different dietary lipids on the fatty acid profiles of eggs produced by 20 and 54 wk old Dekalb laying hens were investigated. Laying hens were subjected to three defined treatments according to the source of lipid added to their diets: soybean oil, beef tallow, and a control diet (without the addition of oil). The experimental design was in a 3x2 factorial arrangement (three treatments and two different ages). The fatty acid composition of the yolks in the eggs produced by the laying hens was analyzed. The eggs produced by laying hens on the soybean oil diet had a large amount of polyunsaturated fatty acids (PUFA) omega-6 (n-6) and omega-3 (n-3) in their yolks (23.55, 2.30% respectively), whereas egg yolks from hens who were given beef tallow had higher percentages of monounsaturated fatty acids (47.53%) compared to soybean oil (47.53%) and the control diet (38.72%). The percentages of trans fats present in the egg yolks in all treatments were considered very low (0.91; 0,11; 0.05%). Young layers are more efficient at depositing n-3 fatty acids (1.40%), specially C22:6 (0.76%) with the best ratio n6:n-3 (13.97) compared to old layers (1.35; 0.72; 14.81% respectively). Based on these results, it was concluded that the amount of fatty acids present in the egg yolks can be modified by the sources of lipids included in the diet and that independent of the sources of lipid in the diet and the age of the chicken, egg yolks have insignificant amounts of trans fatty acids.

An experiment was conducted to determine the effect of feeding concentrate diets containing varying levels of groundnut haulms on dry matter intake, nutrient digestibility and nutrient balance in Friesian x Bunaji bulls. The feed consisted of four concentrate mixed diets formulated to contain on average 14.45- 14.65% crude protein. Groundnut haulms (GH) in the concentrate diets were on nitrogen basis at 0, 25, 50 and 75% levels with control diet having 0% inclusion of GH. Sixteen bulls aged 12-18months were divided into four each and were randomly allotted to the four treatment diets in a completely randomized design for metabolic trial. During trial, the bulls were housed in metabolic crates and fed Gamba hay adlib and the basal or particular test concentrate mixture at 40% of estimated DM intake. Chemical composition and energy contents of the diets were determined. Dry matter intake (D M ) and organic matter intake (OMI) were also determined. The CP value averaged 14.45±0.44 - 14.65±1.22% for the four experimental diets. The metabolizable energy content expressed in Kcal/kg of diets decreased with increase in GH level from 0-75% (3166-1752 kcal/kg). There was no significant (P>0.05) difference on voluntary DMI and OMI. The digestibility coefficients of DM, OM, CP, CF, EE, NDF, ADF, hemicellulose and ash were significantly (P<0.05) higher at 75% level of groundnut haulms. CF and ADF digestibility were significantly influenced (P<0.05) when groundnut haulms level reached 25%. Conversely, the digestibility of NFE did not differ (P>0.05) across treatments. Nitrogen balance were similar (P>0.05) among animals fed concentrate mixtures. Nitrogen balance expressed in percent was slightly higher at 75% level of groundnut haulms. It is concluded that inclusion of GH in concentrate diets of crossed bulls up to 75% can improve nutrient digestibility and the percent Nitrogen balance.

Abstract: The objective of this work was to evaluate the use of enzyme combinations in diets, with different nutritional uplift matrices, for hens raised in an alternative cage-free system. The experiment was carried out with 800 Isa Brown laying hens aged 24-30 weeks, distributed in a 2x2 factorial arrangement, with two combinations of enzymes (phytase and xylanase) and two nutritional matrices (conventional and overvalued uplifts). The treatments were: T1, phytase (450 FTU per kilogram) + xylanase (12,000 BXU per kilogram), using matrix I (100 Kcal kg-1 apparent metabolizable energy, 0.16% calcium, 0.15% available phosphorus, 0.03 sodium, and 0.02% digestible lysine); T2, phytase (1,500 FTU per kilogram) and matrix I; T3, phytase (450 FTU per kilogram) + xylanase (12,000 BXU per kilogram), using matrix II (120 Kcal kg-1 apparent metabolizable energy, 0.22% calcium, 0.20% available phosphorus, 0.04% sodium, and 0.05% digestible lysine); and T4, phytase (1,500 FTU per kilogram) and matrix II. Productive performance variables and external and internal egg quality were analyzed. The use of phytase or of the phytase + xylanase combination, independently of the nutritional matrix used, met the nutrient requirements of the animals and maintained their productive performance. However, the combination phytase + xylanase and the adoption of matrix I was more efficient.

Dietary Treatments

The practical usage of untraditional feedstuffs such as sunflower meal (SFM) in laying hens nutrition in developing countries has received considerable attention. SFM is a by-product of the sunflower oil industry and has been progressively added to bird’s diets. Sunflower meal (SFM) is gaining great interest as a feed ingredient due to its eminent crude protein content, low anti-nutritional compounds, and low price. The current experiment was aimed to assess the production efficiency, egg quality, yolk fatty acids composition, and nutrient digestibility of laying hens fed SFM. A total of 162 Bovans Brown laying hens aged 60 weeks old were randomly allocated using a completely randomized design into three experimental groups of nine replicates each (n = six/replicate) for eight weeks. The dietary treatments involved a control (basal diet) and two levels of SFM, 50 and 100 g/kg feed. The dietary treatments did not influence live weight gain, feed intake, and egg mass. On one hand, the laying rate was increased; on the other hand, the feed conversion ratio and broken eggs rate of laying hens were decreased (p < 0.05) by the dietary inclusion of SFM. Dietary treatments had no effect on the egg’s quality characteristics except the yolk color and yolk height were larger (p = 0.01) for laying hens fed SFM compared with those fed the control. Dietary inclusion of SFM decreased (p < 0.05) the content of cholesterol in the egg yolk. Still, it increased the yolk contents of vitamin E, calcium, linoleic acid, linolenic acid, and oleic acid (p < 0.05). Furthermore, the dietary inclusion of SFM increased crude protein and calcium digestibility, but decreased the ether extract digestibility. In conclusion, our results suggested that the dietary inclusion of SFM, up to 100 g/kg at a late phase of laying, could improve the production performance, some of the egg quality traits, and nutrient digestibility while decreasing egg yolk cholesterol.

ABSTRACT. Penelitian bertujuan untuk mengetahui pengaruh penambahan pakan ampas kelapa (AK) yang difermentasi dengan penambahan ammonium sulfat (AS) terhadap produksi dan kualitas telur telah dilaksanakan. Ampas kelapa ditambahkan AS dengan konsentrasi 0, dan 4% dan 0.1% Ragi (Fermipan®) dan diinkubasi selama 5 dan 7 hari. Substrat yang dihasilkan dicampur kedalam pakan dan diberikan kepada 75 ekor ayam petelur fase bertelur umur 20 minggu selama 24 minggu. Pakan perlakuan yang diberikan adalah: pakan kontrol (KTL), kontrol + AK tanpa AS yang difermentasi selama 5 hari (F5-0AS), kontrol + AK dengan 4% AS yang difermentasi selama 5 hari (F5-4AS), kontrol + AK tanpa AS yang difermentasi selama 7 hari (F7-0AS) dan kontrol + AK dengan 4% AS yang difermentasi selama 7 hari (F7-4AS). Penelitian ini menggunakan rancangan acak lengkap dengan 5 perlakuan, 5 ulangan dan 3 ekor ayam per ulangan. Data yang diperoleh dianalisis dengan analisis ragam dan dilanjutkan dengan uji Tukey. Hasil penelitian menunjukkan bahwa konsumsi ransum, produksi telur, bahan kering ekskreta dan kualitas telur dipengaruhi oleh pakan perlakuan (P0,05). Perlakuan tidak memberikan pengaruh yang nyata (P0,05) terhadap bobot telur, kecernaan bahan kering, persentase kerabang telur, indeks telur dan tinggi albumen. Total bobot telur tertinggi diperoleh pada ayam yang diberi perlakuan fermentasi baik tanpa ataupun dengan penambahan AS. Fermentasi selama 7 hari dapat meningkatkan produksi henday dan jumlah telur. Kualitas terbaik dari aspek indeks kuning telur dan Haugh unit adalah pada perlakuan F7-4AS. Penelitian dapat disimpulkan bahwa fermentasi dapat meningkatkan total bobot telur dan AS dapat meningkatkan kualitas telur dalam bentuk Haugh unit.  (The effect of coconut dregs fermented with the addition of ammonium sulfate on production and quality of eggs) ABSTRAK. An experiment was done to determine the effect of coconut dregs (CD) with the addition of ammonium sulfate (AS) prior to fermentation on productive performance and egg quality. Coconut dregs were added with 0 and 4% AS and 0.1% yeast S. cerevisiae (Fermipan®) after autoclaving. The substrates were incubated for 5 and 7 days and mixed into diets and offered to 75 laying hens for 24 weeks. The experimental diets were: control diet (KTL), basal + 5-days- fermented coconut dregs (FCD) without AS (F5-0AS), basal + 5-days FCD with 4% AS (F5-4AS), basal + 7-days- FCD without AS (F7-0AS), basal + 7-days-FCD with 4% AS (F7-4AS). Data were analyzed using analysis of variance with 5 treatments and 5 replications. Data were further tested by the Tukey test. Results of the study indicate that feed intake, hen day production, total egg, total egg mass, excreta dry matter, yolk height, yolk index, and the Haugh unit were statistically affected by the treatments (P0.05). The effects of treatments were not statistically significant (P0.05) on individual egg mass, dry matter digestibility, eggshell percentage, egg shape index, and albumen height. The highest total egg mass was found in birds fed the FCD diets. Fermentation for 7 days could improve hen day production total egg. The higher yolk index and Haugh unit were produced by the hens fed the F7-4AS diet than those eggs produced by controlled laying hens. In conclusion, fermentation could improve total egg mass and AS supplementation could increase the Haugh unit.
