Alabio duck as one of the genetic resources of South Kalimantan develop rapidly and well-known as an excellent breed of ducks for egg production in Indonesia. However, due to unplanned crossbreeding in the field, presumely  the productivity and the purity of Alabio ducks decreased.   The study is conducted in order to provide information of the characteristics of body weight, body shape, colour of feather, beak, and shank, and also egg production and egg quality of Alabio ducks at duck farming centers in South Kalimantan.  The results indicated that there are uniformity in body weight,  ≤ 1,5 – 1,6 kg for female and  > 1,6 kg for male at 20-24 weeks of age, bottle for of body shape, 60o elavation, but there are variations in some degree in feather colour, beak colour and shank colour of Alabio duks. The feathers vary between batik (strip) or not-strip with cream as the base color. Meanwhile, the colour of beak and shank vary as light yellow, old yellow and orange.  Unless for the higher egg production (91%) in the intensive system and yellow red yolk colour (12,93 RYCF) in the extensive system, egg qualities are not different between production systems.

This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

Effect Of Feeding

The objective of the experiment was to evaluate the effect of the feeding of 80 g/kg (R8) and 100 g/kg (R10) of untreated rapeseed (RS) on egg quality including sensory quality in comparison with a control diet without rapeseed (R0). The addition of iodine (I) was also evaluated (1 mg/kg (R10) vs. 3 mg/kg (R10+I)). “Double zero” RS was used. The contents of energy and crude protein were almost the same in the diets. Laying hybrid ISABROWN was used in the experiment. The quality of eggs was analyzed 11 times every 28 days, from 19 to 64 weeks of age. 30 eggs per each group were always analyzed. Boiled eggs were assessed twice around the peak of egg production. Egg weight decreased (<I>P</I> < 0.001) with the increased level of RS (62.9 g, 61.8 g and 60.7 g, respectively). A reduction in egg weight in R8 and R10 diets resulted in the lower weight of albumen and eggshells. The addition of I to R10 diet increased (<I>P</I> < 0.001) egg weight (62.1 g vs. 60.7 g). The yolk proportion in egg weight was the highest (26.0%, <I>P</I> < 0.001) and the albumen weight ratio was the lowest (64.2%, <I>P</I> < 0.001) in group R8. Iodine supplementation improved (<I>P</I> < 0.001) yolk weight (15.7 g vs. 15.3 g). The proportion of RS in the diet did not affect the eggshell strength. An increase in the level of I improved (<I>P</I> < 0.001) eggshell quality (strength 36.1 N vs. 34.0 N and thickness 0.386 mm vs. 0.363 mm). Taste and overall acceptability were lower (<I>P</I> < 0.05) in eggs of hens fed RS. The addition of I did not affect flavour, odour, taste or overall acceptability.

SUMMARY Birds show poor utilization of phytic phosphorus in their diets because of the lack of endogenous enzymes to digest phosphorus and make it bioavailable. Therefore, the objective of this study was to evaluate phytase supplementation in the diets of laying quails. Eighty quails were used in a completely randomized experimental design with five treatments and four replicates of four birds each. The treatments were as follows: 0.35% Pd; 0.20% Pd; 0.20% Pd + 500FTUs of phytase; 0.09% Pd; 0.09% Pd + 500 FTUs of phytase. The birds were housed in metallic batteries during a trial period of 21 days, for evaluation of egg production, egg weight, feed intake and feed conversion. After being collected, the eggs were sent to the nutrition laboratory of the department of zootechnics of the CEO/Udesc, where analyses of albumin, yolk and shell quality were performed. The results were subjected to analysis of variance, and the differences between the averages were compared using the Tukey test at 5% of significance. No differences (P> 0.05) were observed in terms of performance and egg quality parameters. We conclude that the inclusion of phytase in the diet of laying quails can be accomplished without compromising the performance and quality of the eggs. Additionally, 0.09% of 22 disponible phosphorus can be used to grant adequate performance for 21 days.

The main objective of this research is to evaluate the inclusion of different natural pigment solutions in diets formulated with maize and sorghum solutions on the growth performance and egg quality of commercial laying hens created in hot climates. Throughout the conduction of this experiment, were used 252 laying hens of the Hisex Brow, in a completely randomized design, with six treatments, seven repetitions, and six birds per plot. The experimental diets were assigned with different energy sources and adding pigmentation solutions, diet 1 (corn), diet 2 (corn + annatto), diet 3 (corn + carrot), diet 4 (sorghum), diet 5 (sorghum + annatto), diet 6 (sorghum + Carrot).  Afterward, being evaluated the performance and quality of eggs. It was observed significant difference with reference t egg production, egg weight (g), gem weight (g), the weight of shell (g), albumin in weight (g), and gem coloration (tons) among the treatments. There was no difference in the parameters of performance and quality of eggs evaluated, only the variable yolk color had a significant effect between treatments. Replacing the energy source of the corn diet with sorghum in the diet of laying hens at peak production provides similar performance and egg quality, which can be a substitute for quality and efficiency. The use of annatto and carrots as a natural pigmentation promotes greater pigmentation of the egg yolks of laying Hisex Brown eggs and does not impair the performance of the birds.

The purpose of this study was to determine the effect of Moringa leaf meal (Moringa oleifera) in feed on production performance and egg quality of laying hens. The materials used 120 laying hens of Isa Brown breed in 38 to 42 weeks age. The method used an experimental trial by Moringa oleifera addition in the basal feed. The experiment were devided into four groups i.e. without Moringa oleifera as control (P0), with Moringa oleifera 0.5% (P1), 1% (P2), 1.5% (P3) and 2% (P4). Variables observed were the appearance of egg production and quality. The data was analyzed by Completely Randomized one way design. The mean differences were calculated by the Duncan Multiple Range Test. The results showed that administration of Moringa leaf powder can increase the production and quality of eggs in laying hens. Addition of 2% Moringa leaf powder in the feed gives the best effect on the appearance and quality of production and egg. This research suggested the addition of 2% Moringa leaf powder was recommended in order to obtain the finest appearance and quality of production.

This study aimed to evaluate the introduction of cassava flour, moringa leaf meal and bocaiuva pulp in laying hens’ diets on egg quality. Nine hundred eggs from Dekalb® White laying hens between 34 and 54 weeks of age rearing in semi-intensive system were used in the experiment. The laying hens were submitted to the following diets: 1 - diet control: maize and soybean meal base diet; 2 - diet with inclusion of 18% of cassava root meal+4% moringa leaf meal+4% of bocaiuva pulp; 3 - diet with the inclusion of 24% of cassava root meal+6% of moringa leaf meal+6% of bocaiuva pulp; 4 - diet with the inclusion of 30% of cassava root meal+8% of moringa leaf meal+8% bocaiuva pulp. The inclusion of higher levels of alternative ingredients intensified yolk color; it improved the percentage of albumen, yolk index, specific gravity and reduced yolk percentage. The association of 30% de cassava root meal+8% de moringa leaf meal+8% de bocaiuva pulp does not decrease the egg quality; it gives the yolk an orange yellow tone and it can be used in diets of laying hens with 34 and 54 weeks of age in semi-intensive systems.

The differences in egg production traits in six laying hen genotypes (brown-egg hens Bovans Brown, Bovans Sperwer, ISA Sussex; white-egg hen Dekalb White; laying hens with tinted shells Moravia Barred and Moravia BSL) and the interactions of genotype and oviposition on egg quality were evaluated. The genotype affected the laying rate (P ≤ 0.003), mean sequence length (P ≤ 0.001), and time of oviposition (P ≤ 0.001). The brown-egg genotypes laid eggs approximately 1 h earlier than the white-egg genotypes and approximately 2 h earlier than the tinted-egg genotypes. Egg shell strength was the lowest in tinted-egg genotypes (P ≤ 0.001) and declined with the time of oviposition (P ≤ 0.002). Egg shell percentage (P ≤ 0.011) and thickness (P ≤ 0.011) were affected by the interaction of genotype and oviposition. None of the effects affected egg weight; however, the proportion of egg components was significantly influenced by the interaction of genotype and oviposition. The study confirmed that the differences in the egg production and egg quality of various genotypes are associated with the laying pattern.
