Inclusion Level

Hulless barley (var. Scout) was evaluated as a potential feedstuff for laying hens in two experiments. In exp. 1 hulless barley was substituted for wheat at four dietary levels (20, 40, 60 or 80%) and in exp. 2 hulless or conventional barley was substituted for wheat at two dietary levels (35.7 or 71.4%). Increasing dietary hulless barley had no effect on egg production or body weight in exp. 1 while feed consumption and feed conversion were significantly lower and egg weight and specific gravity significantly higher. In exp. 2, addition of hulless barley increased hen-day production and decreased egg specific gravity in comparison to hens fed a wheat diet. At the 35.7% dietary inclusion level, hulless barley resulted in more eggs with higher specific gravity than for hens fed conventional barley. Hens fed 71.4% hulless barley were heavier and produced larger eggs than hens fed the same level of conventional barley. It may be concluded that hulless barley was at least equivalent to wheat and surpassed conventional barley as a cereal grain for laying hens. Key words: Laying hens, hulless barley, barley

The study was conducted to determine the effect of organic acids supplementation on body weight changes, feed intake, feed efficiency, egg production, egg weight and egg quality in laying hens at age between 67 and 74 weeks. A total of 48 Shaver 579 laying hens of 67 weeks age were allotted into 4 groups, each containing 12 hens. The hens were fed basal diet (17% CP and 2800 kcal ME/kg diet) supplemented with 0 (T1), 260 (T2), 520 (T3) and 780 ppm (T4) of organic acid mixture (fumaric acid and salt of butyric, propionic and lactic acids). The results revealed no effect of organic acids supplementation on body weight change and feed intake but improvement of egg production and feed conversion were observed. Organic acids supplementation significantly increased egg production by about 2.26, 8.0 and 9.84% on 260, 520 and 780 ppm respectively when compared with the untreated group (P<0.05). Feed conversion showed a significant (P<0.05) improvement in laying hen groups which fed on the basal diet supplemented with organic acids at 260, 520 and 780 ppm by about 1.85, 8.48 and 7.74% respectively when compared with the control. On the other hand, dietary organic acid had no effect on the average egg weight, while showed a lower percentage of large (P<0.05) and extra large egg (P<0.01) size compared with control group. Body composition parameters were not affected (P>0.05) by dietary treatments. Inclusion of organic acids improved egg shell thickness (P<0.05) while significantly reduced albumen index (P<0.05). Incorporation of organic acids attributed to significant increase per cent albumen (P<0.01) and significant decrease in yolk per cent (P<0.05). It can be concluded that organic acid supplementation of laying hens diet may improve persistency of lay and feed conversion. From economical point of view, it is concluded that organic acid addition (520 ppm) may result an economic benefit of layer production at older age.

Three experiments were conducted to evaluate the effects of β-glucanase/pentosanase enzyme complex (Trichoderma viride, Roxazyme® G) on the performance of Leghorn chicks and laying hens fed wheat, barley, oats or rye diets. In the first experiment, enzyme addition (0.2 and 0.4 g kg−1) improved weight gain and feed efficiency in Leghorn chicks fed hulless barley (45 and 18%, respectively) and naked oat-based diets (35 and 15%, respectively). No response to dietary enzymes was evident when chicks were given the wheat diet. In the second experiment, the addition of Roxazyme® G to diets containing hulless barley (0.1 g kg−1) and rye (4.0 g kg−1) improved feed consumption (8 and 16%, respectively), weight gain (21 and 35%, respectively) and feed-to-gain ratios (11 and 14%, respectively). Relative gizzard weights of birds fed the rye diet were reduced by 18% when enzyme was added to this diet. In the third experiment, replacing all the wheat with hulless barley, naked oats or rye in diets for young pullets had no effect on overall performance during a 12-wk laying trial. Vent feather soilage increased with the incorporation of naked oats and rye. Enzyme supplementation had a beneficial effect on weight gain and feed intake but not on egg production, initial egg weight, average egg weight, egg specific gravity, Haugh unit score, and mortality.

Inclusion Level

The study was conducted to evaluate an appropriate inclusion level of white-flowered semi-leafless green spring peas in diets for laying hens. Egg production and egg quality variables (specific weight, Haugh unit, shell strenght) were determined with 576 hens in a 52-week feeding experiment, which comprised of three feeding phases. The hens were offered one of the four cereal and soybean meal (SBM) based experimental diets. Peas were tested in proportions of 0, 100, 200 or 300 g kg-1 in the diet. Pea inclusion had no effects on production performance, feed consumption or feed conversion ratio (FCR) of the hens during the entire trial. The pea inclusion impaired FCR during the second feeding phase (p < 0.05) and increased birds’ live weight in a linear manner during the second and the third feeding phases (p < 0.05). Pea inclusion had no effects on egg quality. It can be concluded that at least 300 g kg-1 of the studied peas can be used in the diets of laying hens without negative effects on production performance or egg quality.

Abstract. This study was carried out to investigate the effects of fluctuate lighting on performance of laying hens. Two programs were applied with 16 hours daily lighting: step-up (normal) lighting program as the control treatment and a fluctuate lighting program of 2 W/m2 for 45 min and 6 W/m2 for 15 min. Egg weight, feed consumption, feed conversion ratio, henday egg production and hen-housed egg production of the laying hens were recorded for 46 weeks. No significant difference for hen-day and hen-housed egg production between the step up and fluctuate lighting programs (P>0.05) were found. However, fluctuate lighting program resulted in a significant increase in egg weight (P<0.05). Moreover, hens in the fluctuate lighting program consumed significantly less amount of feed and had a better feed conversion ratio than hens in the step-up lighting program (P<0.01). The results of the present study indicate that fluctuate lighting can be used for a profitable egg production.

Initial body weight may affect animal performance. This study investigated the effect of divergent selection based on body weight and betaine supplementation on performance of quails in the tropical environment. In total, 900 7-day-old female Japanese quails were divided into 30 cages of 30 birds in a 3×2 factorial design. The first factor was body weight (Random, High, and Low), and the second factor was betaine supplementation (0% and 0.14%), resulting in 6 treatments. Performance data were collected for 2 periods of 28 days during the laying phase. The variables observed included feed consumption, egg production, egg weight, and feed conversion. The data were analyzed using analysis of variance and continued with Duncan’s Test for significant results. The results showed that there was no interaction between body weight and betaine supplementation on quails’ performance. Random body weight produced more eggs and the highest feed efficiency than Low body weight (P<0.05), although the result did not differ from High body weight. Betaine supplementation enhanced egg weight (P<0.05) than the non-supplemented group but did not affect other variables. It is concluded that Random and High weight and betaine supplementation can be applied to optimize the performance of quails in a tropical environment.

 This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 160 Dekalb White hens with 52-wk old were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost.
