Feeding time under performance and eggs quality of quails in production

SUMMARY In order to evaluate the performance and egg quality of quails on different time feeding, One hundred ninety two Japanese quail (Coturnix coturnix japonica) at 24 weeks of age were distributed in a completely randomized design with two replications and twelve treatments eight birds each. The treatments consisted of two different times of feeding at 6h and 16h. The performance was evaluated by the feed intake (g/bird/day), egg production (%), egg mass (g), feed conversion per egg mass (kg/kg ), feed conversion per dozen eggs (kg/dz) and viability (%). The egg quality was evaluated by the eggshell thickness (mm), percentage of albumen, yolk percentage and average egg weight (g). The feeding time at 16h favored the performance of Japanese quails at 26 and 34 wk of age considering egg production, egg mass and average egg weight. Thus, it is recommended to feed the quails at times that coincide with the highest egg laying intensity, which ranges from 16 to 19h.

The aim of this study was to evaluate the effects of vegetable glycerin on performance and egg quality of red-egg layers in the second production cycle. A total of 252 Hy-Line Brown layers weighing 1.919 ± 0.095 kg, at 90 weeks, were used in a completely randomized design with six treatments and seven birds per replication. The experiment lasted 84 days. Treatments consisted of a control diet (no glycerin) and five diets with increasing levels of vegetable glycerin (2, 4, 6, 8, and 10%). The following variables were evaluated: feed intake (g/bird/day); egg production (%); egg weight (g); egg mass (g/bird/day); conversion per egg mass (kg kg) and per dozen eggs (kg/dz); percentages of albumen, yolk, and shell; eggshell thickness (mm); and egg specific gravity. (Y = 67.69 + 54.23X, R2 = 0.78) and egg mass (Y = 44.84 + 42.87X, R2 = 0.66) improved linearly with the glycerin levels. A quadratic effect was observed (Y = 114.11 + 336.96 X – 3,169.6 X2, R2 = 0.52) on feed intake. In conclusion, glycerin can be used to partially replace corn in diets for layers in the second production cycle at inclusion levels of up to 10%.

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

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 aim of this study was to evaluate levels of inclusion of pinto beans in diets for quail in the laying phase on their performance and egg quality. A total of 280 Japanese quail in the laying phase were distributed into five treatments in a completely randomized design with eight replicates and seven birds per plot. Treatments consisted of five levels (0, 2, 4, 6, and 8%) of inclusion of pinto beans in the diets, which remained isoenergetic and isoproteic. The experiment began with the quail at 70 days of age and lasted 63 days, with their performance assessed every 21 days and egg-quality parameters on the last two days of each cycle. The following parameters were evaluated: final weight, feed intake, egg-laying rate, feed conversion (per dozen eggs and per egg mass), egg weight, eggshell thickness, specific gravity, yolk color, and weights of shell, yolk, and albumen. No difference was detected between the bean inclusion levels for any of the performance and egg-quality traits assessed or the birds' final weight. In conclusion, up to 8% raw pinto beans may be added in diets for Japanese quail in the laying phase without compromising their performance or internal-external egg quality.

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

Five layer diets were formulated containing 0.5,10, 15 and 20% Anthonotha macrophylla seed meal which replaced equivalent proportion of groundnut cake. One hundred and eighty Babcock brown layers already 3 months in lay were randomized into 5 groups and each group was fed one of the experimental diets for 84 days. The hens were examined for performance using body weight. teed intake, henday egg production, egg weight and feed conversion ratio. The interior quality of Eggs were also assessed. Total feed intake ranged from 9.27 to 10.97kg, average daily feed intake, from 110.32 to 130.54 g/bird/day, hen-day egg production, from 48.88% to 79.11% and feed conversion ratio, from 1.87 to 2.15. Statistical analysis showed that total feed intake, average daily feed intake and hen - day egg production were similar across the dictary treatments up to the 15% level of inclusion, but were significantly depressed (P<0.05) at the 20% inclusion level. However, diet had no significant effect on final body weight and average egg weight and feed conversion ration (P>0.05). Similarly results on egg quality showed no significant effect (P>0.05) on albumen index, yolk index, yolk colour, Haugh unit and shell thickness. Based on these results, it was concluded that Anthonotha macrophylla seed meal can be incorporated into layer diets up to 15%, inclusion level without incurring a depression in performance Layer diets containing this meal ingredient had no deleterious effect on egg quality.
