This experiment was conducted to evaluate the effect of levels of calcium (Ca) and particle size of limestone (LS) for laying hens. It was used 216 Dekalb White laying hens at 25 to 49 weeks of age in a completely randomized design in a 3 × 2 factorial arrangement, composed of three levels of calcium (3.92, 4.02 and 4.12%) and two particle sizes of limestone (thin - 0.60 mm; and thick - 1.00 mm), resulting in 6 treatments with six replicates of six birds. There was no significant effect of levels of calcium and limestone particle size neither of the interaction calcium × particle size for feed intake, egg weight, specific gravity, shell thickness, shell percentage, Haugh unit, calcium and phosphorus digestibility and percentage of digestive tract. Production, mass, conversion by mass and conversion by egg dozen had their best results with 4.12% of calcium in the diet. Percentage of gizzard and feed intake observed at 3:00 p.m. improved as limestone granulometry improved from 0.60 to 1.00 mm. There was an interaction effect among calcium level and limestone granulometry for breaking strength of tibia, bone density, length of the small intestine and feed intake at 6:00 a.m.; 9:00 a.m., 12:00 p.m., 6:00 p.m. and 9:00 p.m., respectively. It is recommended the addition of 4.12% of calcium and limestone in the thick granulometry (1.00 mm) for a better performance of commercial laying hens. More studies are needed to elucidate the mechanisms involved in the alteration of nutritional behavior of laying hens in response to changes in the levels of calcium and in the granulometry of limestone in the rations.

Abstract:The objective of this work was to evaluate the effect of limestone particle sizes in the diet and of lighting regimes on the egg and bone quality and on the performance of commercial laying hens. Three hundred Hissex White layers, at 18 weeks of age, were distributed in a completely randomized design, in a 5×2 factorial arrangement (coarse limestone in the diet at 0, 25, 50, 75, and 100%; with or without artificial light), with five replicates of six birds. No significant interaction was observed between particle sizes and lighting regime for the evaluated parameters. There was no significant effect of coarse limestone level in the diet on the performance and egg quality of hens; however, bone deformity (3.23 to 4.01 mm), strength (5.19 to 6.70 kgf cm-2), and mineral matter (51.09 to 59.61%) improved as the proportion of coarse limestone increased. For lighting regime, the treatment with artificial light yielded higher Haugh unit values (87.17 vs. 85.54) than that with natural light only. Greater limestone particles improve bone quality of laying hens, and the use of artificial light can benefit the albumen quality of the eggs.

Abstract This research aims to study and analyze the effect of adding turmeric flour (Curcuma domestica Val) in the rations on the performance of 70 weeks old Isa Brown strain of laying hens. The research method used in this study was an experimental method with a completely randomized design (CRD) step with five treatments and four replications. The number of chickens used was as many as 40 laying hens. The treatments given to the sample were P0 = feed without giving turmeric flour (control), P1 = feed with 0.3% turmeric flour, P2 = feed with 0.5% turmeric flour, P3 = feed with 0.7% turmeric flour and treatment P4 = feed by giving turmeric flour 0,9%. The results showed that giving turmeric flour in the rations of the Isa Brown strain of laying hens affected chicken performance and egg quality. This research concludes that giving turmeric flour a percentage of 0.7% in Isa Brown’s 70-week old laying hens is the best for ration consumption, Hen Day Production, egg weight, feed conversion, and egg quality: Haught Unit, yolk egg color, yolk egg index, grading egg and egg mass. Based on the haugh unit value, all eggs produced are still in the AA grade category

SUMMARY This study was performed to evaluate the effect of the inclusion of paprika and marigold extracts in sorghum-based rations on the productivity and egg quality of laying hens. One hundred sixty laying hens were distributed in a completely randomized design in five treatments and in a factorial arrangement (2 × 2 + 1), one control ration based on corn, two levels of paprika extract (0 and 6 g/kg diet), and two levels of marigold extract (0 and 1 g/kg diet) in sorghum-based rations. There was no effect (P > 0.05) of the treatments on the weight, specific weight, and Haugh unit of the eggs and productive performance, but the inclusion of paprika extract resulted in eggs with lower egg pH. The interaction between the control group and the factorial was significant (P < 0.05) to the laying rate, egg mass, and yolk color, whose values were lower with sorghum-based diets with no pigment compared to control treatment. The interaction between the paprika and marigold extracts was significant increasing the height (P < 0.03) and color (P < 0.0001) of the yolk when paprika extract was used, with or without marigold extract. Marigold extract inclusion reduced the percentage (P < 0.02) and thickness (P < 0.01) of the eggshell. As conclusion, the inclusion of paprika extract in sorghum-based diets for laying hens is viable for improving the egg quality.

ABSTRACT Biochar, which has emerged as an important form of the transformation and final disposal of biomass, can be used directly in soil or in seedling nurseries. In this study, the use of biochar of different particle sizes and percentages was evaluated in replacement to a conventional substrate used in the production of sugarcane seedlings. To this end, an experiment was carried out based on a completely randomized design, with a 5 × 4 factorial scheme, consisting of five different percentages of biochar (with 0, 25, 50, 75, and 100% v/v substitution of the conventional substrate) and four particle sizes (<1, 2, 4, and 9 mm), with nine repetitions. As seedling growth variables, the average sprouting time, sprouting speed index, plant height, leaf number, leaf length, and width + 2, as well as the dry mass of the aerial parts and roots were evaluated. Irrespective of the percentage of commercial substrate replaced with biochar, sprouting time was found to be shorter when 6-mm-diameter biochar particles were used. With respect to the sprouting speed index, it was found that regardless of particle size, the highest value occurred when biochar was used to replace 42% of the commercial substrate. The substitution of the commercial substrate with biochar had the effect of reducing the growth of sugarcane seedlings.

Performance and egg qualities of old-laying hens fed with diets containing ginger, turmeric and garlic were evaluated in a twelve (12) week feeding trial. A total of 135 laying birds of Isa-Brown strain which were sixty-four (64) weeks old were used for the trial and arranged in a completely randomized design. Five diets were formulated for the trial:  Diet 1 (control), Diet 2 (3% inclusion level of turmeric), Diet 3 (3% inclusion level of ginger), Diet 4 (turmeric and garlic at 2.25% and 0.75%, respectively) and Diet 5 (ginger and garlic at 2.25% and 0.75%, respectively). Proximate compositions of the Phytogenic Feed Additives (PFAs) were determined with the moisture content ranging between 5.03-7.50%; ash (3.26-6.11%); ether extract (7.39-14.58%); fibre (10.28-13.79%); protein (3.07-7.23%) and Nitrogen Free Extract (58.88-61.54%). The performance indices, though not significantly (P˃0.05) influenced by the test diets except for Hen Day Production (HDP) had the highest weight gained (0.16kg) recorded for birds fed on a diet containing ginger. The highest (62.92 and 62.04 %) HDP were observed in birds fed diets containing ginger and ginger + garlic; respectively. However, the lowest weight gained (0.04kg) was recorded in birds fed a diet containing turmeric + garlic; this diet also recorded the lowest % HDP and FCR with values of 57.50% and 2.37 respectively. The overall values for the qualities of eggs from laying hens fed the PFAs showed that only the Haugh Unit, yolk colour and albumen height were significantly (P˂0.05) affected; with those on Turmeric + Garlic diets having the highest for these parameters. However, the fatty acid variables were not significantly (P˃0.05) affected by the dietary treatments. It could be concluded that the inclusion of PFAs in the diets of laying hens especially at an older age would help to sustain performance with improved quality.

A total of one hundred and fifty, a day-old keets were used in an experiment arranged in a Completely Randomized design (CRD) with the aim of determining the effect of feed particle size on the performance of the keets. The keets were randomly divided into three treatment groups viz; 1, 2 and 3mm particle sizes having 45 keets each. These were further subdivided into three replications of 15 keets per replicate. The keets were reared for 56 days post 21days of brooding. They were fed and watered ad libitum. Data collected were subjected to One-Way Analysis of Variance. The proximate composition of the feed particle sizes were statistically similar (P>0.05) in contents. The results obtained revealed significant (P<0.05) differences in all the parameters considered with the exception of the initial weight. The keets on 2mm feed particle size had the highest final weight of 1529.73 ± 8.74g/bird; the highest weight gain of 26.85 ± 0.16g/bird/day; the highest feed intake of 44.50 ± 0.54g/bird/day; the best feed: gain of 1.66 ± 0.03 and the best protein efficiency ratio of 3.10 ± 0.05. The highest mortality of 33.33 ± 0.00% (n = 15) was recorded in keets fed 3mm feed particle size. The results showed that birds fed 2mm feed particle size depicted potential for efficient utilization of feed which is related to the fine texture of the feed. Hence, it could be concluded that keets up to 11 weeks of age can be managed effectively on feed particle size 2mm.

This study used the AUDI’s technology application with repair rations, aimed at increasing the productivity of Arab’s hens in the 2 nd phase. The repair ration is focused on the addition of calcium minerals. AUDI technology is a combination of water filtering technology with extract beluntas (Pluchea indica L.). The research used seventy two Arab’s hen with homogenous body weight. The study used a completely randomized design with 3 treatments, 6 replications, each replication consisting of 3 chickens. The research was conducted in 6 weeks of treatment. The parameters measured in this study were ration consumption, calcium consumption, hen day production (HDP), eggshell weight, and thickness. The results showed that the use of AUDI technology on rations significantly improved (p <0.05) affected ration consumption, calcium consumption, and increased hen day production (HDP), but did not affect weight, and thickness of an eggshell. Feed intake and calcium consumption significantly influenced by differences in calcium and crude protein in the rations. Based on these results, it was found that the use of AUDI technology was able to shorten the clutch cycle in laying hens so that production still reached 60-70% equivalent with phase I. Weight and thickness of eggshells were not affected by the use of AUDI technology and improved rations because the hens used as subject had reached peak production.

Non-conventional feeds are generally of low quality so feed fermentation needs to be done to increase its use. This research was conducted to examine the effect of giving fermented feed types on egg quality. This research was conducted in June until August 2018 in the cage of Cibadak poultry in Sukabumi district. The animals used in this study were 24 Brown Strain Isa Brown laying hens as many as 24 birds. The study used a completely randomized design (CRD) consisting of 6 treatments and 4 replications. The treatment in this study was R0 = 100% Basic Ration, R1 = 90% Basic ration + 10% fermented non conventional ration, R2 = 80% Basic ration + 20% fermented non conventional ration, R3 = 70% Basic ration + 30% Non ration conventional fermented, R4 = 60% Basic ration + 40% Fermented non-conventional ration, R5 = 50% Basic ration + 50% Fermented non-conventional ration. The data obtained were analyzed using Analysis of variance (ANOVA), if the data showed results that were significantly different (P <0.05) followed by the Duncan test. The results showed that substitution feeding did not significantly influence the egg index, egg white weight, Haugh Unit value, and shell thickness. Therefore, it can be concluded that demonstrable non-conventional feed can be given in ration of laying hens up to 50%.

Microbial Phytase

The aim of the present experiment was to examine the interaction between particle size and microbial phytase supplementation on the performance, nutrient utilisation and digestive tract development of broiler starters fed maize-based diets. The experimental design was a 2 × 2 factorial arrangement of treatments evaluating two maize particle sizes (medium and coarse) and two levels of phytase supplementation (without or with 500 phytase units/kg diet). The two particle sizes were achieved by grinding the whole maize in a hammer mill to pass through 3- and 7-mm screens, respectively. Broiler starter diets, based on maize and soybean meal, were formulated to meet recommended requirements for major nutrients, except phosphorus. Each of the four diets was fed ad libitum to six pens of eight male broilers each, from day 1 to day 21 post-hatching. Phytase supplementation increased (P < 0.001) the feed intake and weight gain, and lowered (P < 0.05) feed per gain in both medium and coarse particle size diets. Coarse grinding improved (P < 0.05) weight gain, but had no effect (P > 0.05) on feed intake and feed per gain. No interactions (P > 0.05) between phytase supplementation and particle size were observed for any of the performance parameters. Phytase supplementation increased (P < 0.001) ileal phosphorus digestibility and toe ash content of birds fed the medium particle size diet, but had no effect in those fed the coarse particle size diet. Apparent metabolisable energy and ileal digestibility of calcium and nitrogen were not influenced by particle size or phytase supplementation. The present findings suggest that the effectiveness of supplemental phytase on broiler performance is not influenced by the particle size of maize.
