Effect of Dietary Black Cumin Seeds (Nigella Stavia),Garlic(Allium Sativum)and Lettuce Leaves (Lactuca Sativa) on Performance and Egg Qualty Traits of Native Layer Hens

This work is done in rental house at Shaqlawa/Erbil city and It has been adapted to be a typical miniature field for experiment. (two month rearing ),for native layer at age (35week). Aimed of this experiment to investigate the effect of dietary 5% individual powder of black seeds, garlic and grinding of lettuce leaves on performance and egg quality traits of layer Hens. Atotal number of 64 layer distributed for four treatments, each of treatment included 16 hen and 4 cock, The treatments were as follows : T1 (control) without any addition, T2: 5% black cumin seeds powder, T3: 5% garlic powder, T4 : 5% lettuce leaves grinding. Result observed that T4 impact to improve the egg performance and color yolk egg, best value pointed in T1 for eggs phenotype characterized further for Albumin, yolk length/cm and significant (P≤0.05) with other treatments. Results also shown in T3 were the best value for egg shell strength (Kg/cm2). T2 observed better value for thickness, egg shell weight/g and percentage of egg shell. T3 obtained best value for yolk height and yolk Albumin index egg and H.U, followed by T2.

Laying Performance, Egg Quality Characteristics, and Egg Yolk Fatty Acids Profile in Layer Hens Housed with Free Access to Chicory- and/or White Clover-Vegetated or Non-Vegetated Areas

This study investigated the laying performance, egg quality, and egg yolk fatty acids (FAs) and cholesterol content in layer hens housed with free access to chicory- and/or white clover-vegetated areas. During a 16-week study, 400 Lohmann Brown hens (32 weeks old) housed with free outdoor access were allocated randomly into four groups, each with four replicates of 25 hens. Control hens were fed a conventional diet with free access to a soil area (C), whereas other hens were fed on a conventional diet with free access to a chicory (CI)- or white clover (TR)-vegetated area or a CI and TR mixture (MIX)-vegetated area. The C hens consumed more concentrate feed (p = 0.018) than the TR and MIX hens, which had a higher herbage intake than the CI birds (p < 0.001). The C hens produced eggs with a thicker shell than those in the other treatment groups (p = 0.013). Compared with C, the saturated FAs of egg yolk decreased for MIX (p = 0.010). The polyunsaturated FAs were higher in the MIX eggs than in the C and TR eggs (p < 0.001). Although FAs were distributed in all quadrants of the principal component analysis (PCA), three main FA profiles could be identified based on the loadings of natural groupings in the PC2 versus PC1 plot. The present study shows clear evidence for the contribution of herbage to the hen diet without affecting laying performance. In addition, the FA composition of the CI and MIX vegetation contributed to the production of eggs with preferred FA attributes, such as polyunsaturated FAs and a favourable n-6 to n-3 ratio.

Supplementation of herbals on the production performance and gastrointestinal health of layer hens

This study was conducted to determine the effect of herbals on the production performance and gastrointestinal health of layer hens. There were 50 layer hens used and assigned randomly into two different types of diets namely, basal diet (T0) and basal diet+3ml herbals/1000g ration (T1) with each treatment consisting of 25 birds. Meanwhile, the herbals supplemented into the poultry feed consisted of tumeric, sambiloto leaves, soursop leaves, ginger, and lemongrass. Consequently, the T-test results showed that supplementation of herbals on treatment 1 (T1) statistically had no significant difference with treatment control (T0). The study concluded that the herbal mix could be used as a feed supplementation in a layer basal diet.
