Two experiments were conducted in which rye replaced wheat as the cereal component of laying hen diets. In the first experiment laying hens were fed graded levels of Puma rye (0.0, 19.5, 39.0 and 78.0% of the diet) substituted for Glenlea wheat throughout a 280-d egg-production cycle. Rye-based diets supported comparable productive performance to wheat with respect to hen-day egg production, feed conversion, and body weight gain when the level of rye was 39.0% or less of the diet; however, performance declined at the higher rye level. For the second experiment Glenlea wheat was replaced by Gazelle rye (0.0, 23.3, 46.7 and 70.0% of the diet) when laying hens were in a latter phase of egg production, with the trial period commencing at 44 wk. Substitution of rye for wheat did not significantly affect egg production, feed consumption, egg weight, shell elasticity, or tibia ash at lower rye levels (< 46.7%), although there were indications of poorer performance at high rye levels (70.0%). Increasing the nutrient concentration of diets containing high levels of rye was not an effective means of alleviating poor performance induced by feeding rye in either experiment.

This study was carried out to evaluate the energy levels in the diet to obtain better performance rates and quality of eggs from laying hens in the second production cycle. One hundred and eighty Bovans Goldline laying hens with 62 weeks of age were used during four 28-day periods. A completely randomized experimental design was used with four metabolizable energy levels (2,650, 2,725, 2,800, 2,875 and 2,950 kcal/kg), each with six replicates of six birds. The energy level of diet did not affect the weight of the egg, yolk, albumen and eggshell, the percentages of yolk, albumen and eggshell, yolk color and egg specific gravity. Feed intake, egg production, egg mass and feed conversion per egg mass and per dozen eggs increased significantly with increasing levels of metabolizable energy. Feed intake decreased linearly as the energy level in the diet increased. The metabolizable energy levels showed a quadratic effect on egg production, egg mass and feed conversion per egg mass and per dozen eggs. The metabolizable energy level of 2,830 kcal/kg was the most appropriate to promote better performance and quality of eggs from laying hens in the second production cycle.

The aim of this study was to test the use of carrot juice fermentation with probiotics in rations with different levels on the production performance and quality of egg-laying hens. The material used was Lohman Brown strain of laying hens, 27 weeks old with an average initial body weight of 1.69 kg, as many as 45 birds. The research was conducted with experimental methods and used a Complete Design Acal (CRD). The treatment tested was the use of Carrot Extract Fermentation (FLSW) with probiotic SOC in the feed consisting of T1 = 100% basal ration, T2 = basal ration (97.5%) + FLSW (2.5%): T3 = basal ration ( 95%) + FLSW (5%); T4 = basal ration (92.5%) + FLSW (7.5%); T5 = basal ration (90%) + FLSW (10%). The variables observed were production performance (consumption, egg production (HDA / Hen Day Average), egg weight, egg mass, feed conversion and income over feed cost) and egg quality variables (albumin index, yolk index, Haugh Unit (HU), yolk color, albumin pH, yolk pH). The results of the analysis of variance showed that the use of carrot extract fermentation (FLSW) with different levels had a significant effect on feed consumption (Sig.115) and HDA (Sig.063), yolk index value (Sig.087) and yolk color (Sig. 000). , and not significantly different on feed conversion (Sig. 403), albumin index value (Sig. 522), and Haugh Unit (Sig. 259). The conclusion of the research showed that the use of fermented carrot juice waste (FLSW) in the feed of laying hens had an effect on feed consumption, egg production (Hen Day Averag / HDA), yolk index and yolk brightness (yolk color), but had no effect on conversion. feed, Haugh unit and albumin index value. Key words : probiotics, fermentation, carrot juice waste, production performance, egg quality

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P &lt; 0.0003) and feed consumption (P &lt; 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P &lt; 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P &lt; 0.0024) and tibia ash (P &lt; 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves. &nbsp;

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.

Abstract This study was conducted to evaluate the effects of corn protein concentrate (CPC) levels in the diets on laying performance, and egg quality of laying hens. A total of 180 64-wk-old laying hens (2.05 kg ± 0.19 kg of live weight) were randomly assigned to 36 cages (5 birds/cage) with separate feeders, including 6 dietary treatments. Birds were fed 1 of 6 experimental diets containing CPC at different levels (0, 0.5, 1.0, 1.5, 2.0 or 2.5%) for 10 weeks. Diets were isocaloric (2850 Mcal/kg) and isonitrogenous (CP, 15.0%), having similar digestible amino acid profile. Hens were weighed at the beginning and at the end of the experiment to determine BW change. Egg production, feed consumption and egg weight were recorded daily, while egg quality variables were evaluated every 14 days. Data were analyzed using the general linear model procedure of SAS in a complete randomized design. The cage was considered the experimental unit. Linear and quadratic effects of treatment were used for mean separation and significance was declared at P ≤ 0.05. Hens fed CPC maintained BW and gain at an increased rate (Quadraic: P &lt; 0.01). Feed intake increased as CPC increased in the diet (Lineal and quadratic: P &lt; 0.01). Egg production, mass and weight were increased as CPC increased in the diet (Quadraic: P &lt; 0.01). Feed conversion rate was improved as CPC increased in the diet (Lineal and Quadraic: P &lt; 0.02). Shell thickness and breaking strength tended to linearly increased as CPC increased in the diet (P &lt; 0.06). Albumen height and Haugh unit were not altered by dietary treatment (P &gt; 0.25). Yolk color was increased as CPC increased in the diet (P &lt; 0.01). Results from this experiment suggest addition of up to 2.5% CPC in the diet enhances egg production and some parameters of egg quality.

Laying Performance

There is considerable behavioural evidence demonstrating stress reactions in birds. Behaviour of birds can affect their performance parameters. Also, nutritional factors may affect the behaviour of laying hens. Dietary deficiencies, such as minerals can increase feather-pecking behaviour and cannibalism. In the present study, we evaluate the effect of dietary zinc (Zn) on performance and behaviour of laying hens with four treatments (40, 70, 100, 130 mg Zn/kg of diet) with 96 Hy-Line W-36 leghorn hens for 10 weeks. The results showed that egg production for hens receiving 130 mg Zn/kg of diet was significantly higher than for those receiving 40 and 70 mg Zn/kg of diet (P &lt; 0.05). Those hens receiving 130 mg Zn/kg of diet had lower feed consumption compared with those that had other treatments (P &lt; 0.05). Dietary inclusion of Zn caused an improvement to feed conversion ratio (P &lt; 0.05). There was a treatment × time interaction on feeding behaviour that hens received 130 mg Zn/kg of diet spent significantly less time at the feeder than the other treatments. Hens receiving 130 mg Zn/kg of diet spent significantly less time drinking than the hens that received 40 and 70 mg Zn/kg of diet. Also, those that received 130 mg Zn/kg of diet did more non-nutritive pecking and preening than the hens that received 40 and 70 mg Zn/kg of diet. High levels of Zn decreased the aggressive behaviour of hens compared with those that received 40 mg Zn/kg of diet (P &lt; 0.05). It can be concluded that Zn can improve laying performance, and can decrease aggressive behaviour.

This experiment studied the effects of perches in furnished cages on behaviour and feed consumption of laying hens. The study used 352 Lohmann Selected Leghorn (LSL) hens. The hens were housed at 16 weeks of age in furnished cages in groups of 8 birds. The experiment lasted for 205 days. The treatments were: perches present from 16 weeks of age (P16), perches present from 19 weeks of age (P19), and no perches present (NP). Feed consumption and egg production were measured over the pre-laying period and six 4-week laying periods. The number of hens on perch, in nest and litter box was recorded at various ages. The behaviour of 3 hens per treatment was observed using instantaneous sampling at every 5 minutes, so that the observations of each hen covered one light period (14.5 hours). The treatments had no significant effects on feed consumption after the pre-laying period. Feed conversion ratio (kg feed kg-1 eggs) was favourable in P16 in comparison to NP during the periods 2–4. During the observations after the lights-out NP birds tended to be more frequently in nests, than P16 birds. NP birds spent more time on the cage floor, were recumbent more often, and sitting more rarely in comparison to P16 birds. Based on the results of this study, perches may have advantageous effect on feed conversion ratio in furnished cages.;

This study was conducted to compare the use of two types of feed on production performances of laying hen (feed consumption, egg production, feed conversion ratio, and population depletion) in Blitar Regency. Data were collected from several laying hen farms in Blitar Regency with survey method. All data were then analyzed both qualitatively and quantitatively. The average feed price of semi self-mixed feed and total self-mixed feeds were Rp 5,031 and Rp 4,752 per kg. Hen received semi self-mixed feed in one period showed 117.5 g/hen/day of feed intake, 70.38% of egg production, 2.62 of feed conversion ratio, and 20.50% of population depletion. Meanwhile, the total self-mixed feed resulted 118.23 g/hen/day of feed consumption, 71.75% of egg production, 2.39 of feed conversion ratio, and 15.94 of population depletion in one period. The proximate analysis showed that the total self-mixed feed had better nutrient balance compared to semi self-mixed feed, based on SNI 01-3929-2006 standard. As conclusion the total self-mixed feed showed more optimal production performances than semi self-mixed feed.

The aim of the study was to investigate the interaction between exogenous phytase with protease and protein source in laying hens diet. A completely randomised design study with a 2 × 4 factorial arrangement was conducted to observe effects of protein source (soybean vs. yellow lupine seeds diet) and enzyme addition (no enzyme vs. phytase or protease or both) on laying hens performance, bone mineralization and some egg traits. One hundred sixty Hy-Line Brown hens at the age of 18 weeks were weighed and randomly assigned to 10 treatments, each with 16 birds. According to the producer recommendation in diets containing enzymes reduced the level of available phosphorus (50% reduction) and digestible amino acids - 5% reduction. The egg production during the entire experiment was similar in all groups without significant differences. The egg weight was also on an equal level in all treatments and it was about 58g. Birds fed different protein source were characterized by similar feed intake and feed conversion ratio during the whole experiment. The feed conversion ratio (FCR) was about 1.9-2.0 in all groups. Tibia ash was affected by enzymes supplementation. There was an interaction between protein source and enzymes addition. Birds from treatments fed with yellow lupine meal (YLM) diets reached highest tibia ash level in a group with phytase addition and in groups with SMB in a group with phytase and protease mix. The inclusion of enzymes improved the thickness of the shell. There was an interaction between protein source and enzyme inclusion. It was an interaction between experimental factors in shell breaking strength. Stronger eggshell was laid by hens from groups fed with the inclusion of yellow lupine meal. Addition of phytase had a positive impact on increasing the strength of eggshell. Only inclusion of enzymes affected significantly on shell elastic deformation in part I of eggs. Eggs from hens fed diets with inclusion of protease and phytase mix were most resistant to elastic deformation.
