Effects of ginger or ginger and thyme extract in laying hens feeding on productive results and eggs quality

The aim of this research is to know potention of the egg shells mill in ration toweard eggs production and Quality of the layer chiken. This research was conducted in August 2020 at Apitaik West Lombok, laboratory of Animal nutrition Animal Husbandri Mataram Univercity and laboratory of BPTP East Nusa Tenggara. 75 of layer chiken devide into 5 treatment was PI (0% egg shells +50% yellow corn +16% rise bren and 36% KLKS consentrat), P1I (5% eggs shells +50% yellow corn +16% rise bren and 36% KLKS consentrat), P1II (7% eggs shells +50% yellow corn, 36% KLKS consentrat) +16% rise bren), 5 replicetes and each replicates use 5 layer chiken and all of treatment give iso protein and iso energy ration. The parameter in this reaserch was eggs production, feed comsumtion, feed convertion, eggs weight and eggs quality. The result of this research were analysis by varians analysis above completely randomized design (CRD). The result showed that eggs producktion, eggs weight, feed cosumtion and feed convertion non significant effect (P>0.05), but was significant effect (P<0.05) on weight and thick of eggs shell It was concluded that giving egg shells to a level of 7.5% in the feed had enough potential to increase egg production and quality of laying hens with relatively good feed efficiency.

This study was to understand the effect of supplementation probiotic and different levels of citric acid to laying hens diet on eggs quality traits. during five months used 195 laying hens of lohmann brown, 20 weeks old, being distributed in 15 ground pens (1. 5 × 2 m / pen) , 13 hens / pen, were randomly divided in to six treatments (3 Rep. / Treat.). First treatment was feded a standard laying diet without any additive as control, second treatment was feded diet with Iraqi probiotic 0.25%, third treatment was feded diet with Citric Acid 0.3% while fourth and fifth treatments were fed diets with Iraqi probiotic 0.25% and different levels of Citric Acid 0.3 and 0.45% respectively. The results showed an improvement in the eggs quality traits of hens fed the probiotic and citric acid, since significantly increase an achieved in each of eggs weight, shell weight, yolk weight, yolk index, haugh unit and without significant differences in shell thickness and weight of albumin . The effect of addition treatments had been enhanced the eggs quality traits in hens fed a combination addition of probiotic and citric acid compared with hens fed a single addition of probiotic or citric acid, that means get a synergistic effect between the probiotic and citric acid.

Eggs Quality

ABSTRACT: It was possible to evaluate the effect of continuous and intermittent lighting programs with different photophases on the performance and eggs quality of laying hens, applied to the beginning of the laying phase. The authors used 420 Hy-line Brown laying hens with 21 weeks of age, bred on bedding and submitted for six periods of 28 days between the solstice of summer and winter. The three lighting programs were: (PIC) 16 hours of continuos light, intermittent program with initial and final photophases of 15 minutes (PII15) and an intermittent program with initial and final photophases of 30 minutes (PII30). A completely randomized design with ten repetitions of 14 birds was used. The mean values were subjected analysis of variance and analyzed by the Tukey test (5%). The PIC program showed higher feed intake and eggs' mass about the PII15, and the eggs production of birds, in the PIC, was 1.8% greater than the intermittent photoperiods. Programs of light did not change the egg quality. The intermittent programs for semi-heavy laying hens bred on bedding in an open shed, applied at the beginning of the laying phase, reduced the productive performance of the birds without affecting the eggs quality.
