“…Some studies reported that egg production increased when dietary protein content was increased (Leeson & Caston, 1996;Praes et al, 2014), also another study reported that diets with low protein exhibite negative effect on egg production (Keshawarz 1998;Cufadar et al, 2010) in isoenergetic hen diets. However, it was reported that diets with high protein and low energy have a negative effect on egg production (Li et al, 2013;Steenhuisen & Gous, 2016).…”

KeywordsEmbryonal mortality, hatchability, pheasant, protein levels, sex ratio.Submitted: November/2016 Approved: January/2017 ABSTRACTThis study was performed to investigate the effects of crude protein (CP) in diet and sex ratio on egg production, egg and hatching chick weight and hatchability traits in pheasants (Phasianus Colchicus). In this study, the treatment groups were constructed as 15% CP-5:1; 15% CP-7:1; 18% CP-5:1; 18% CP-7:1 for CP and sex (male:female) ratio respectively. The eggs were obtained from 48 weeks old pheasant. In this study, it was determined that there was positive effective on egg production, egg and hatching weight and hatchability of fertile eggs (HFE) for 18% CP. In contrast, fertility (FR) (p<0.05) and hatchability rate of total eggs (HR) (p>0.05), EPEM (p>0.05) and MPEM (p>0.05) tended to decrease with increasing CP. It was found that there was egg production, egg (p>0.05) and hatching weight (p>0.05), FR (p>0.05), HR (p>0.05) and HFE (p>0.05) increased with increasing female for sex ratio. In terms of embryonic mortality, the EPEM (p>0.05) and LPEM (p>0.05) rate decreased with increasing female. For protein levels × sex ratio, it was found that hatchability traits were adversely affected for 15% CP-1:7. Also, it was determined that the lowest EPEM, MPEM and LPEM were determined for 7:1 in 18% CP group. Based on these results, to improve hatchability traits and a lower embryonic mortality rate, it may be beneficial to use 15% CP-5:1 or 18% CP-7:1 for pheasant breeding.

“…Contrary, Samli et al (2006) obtained a significantly (P<0.05) reduced egg production from 93.6 to 87.8%, on 15% dietary rice bran inclusion responsible also for the decreased feed intake. Also, Praes et al (2014) experimented three fiber sources (cottonseed, soybean and rice hulls) and two dietary crude protein levels (12% and 16%) on Isa Brown layers and noticed negative effects on production parameters. Alagawany et al (2015) stated that a content higher than 8.9% CF (26% SFM) will effect negatively the egg production.…”

Fibre inclusion in laying hen diets it is considered a solution to reduce feed formulation costs by improving nutrients absorption and metabolization within the gastrointestinal tract. A 5-wk study was conducted on 200, Tetra SL layers (28 weeks) randomly allocated in 5 groups (C, E1, E2, E3, E4, respectively), with initial average weights of 1732.26±109.35 g/hen, housed (4 hens/cage; 10 cages/group; 40 hens/group). All groups had the same basic feed compound structure (corn, oil, soybean meal and sunflower meal). The conventional diet (C group) contained 2780 kcal/kg Metabolizable energy (ME); 17.5% Crude protein (CP); 4.39% Crude fibre (CF). The experimental diets added 16.56% sunflower meal and 20% rice bran, increasing the dietary cellulose up to 7%. The fibre digestibility was improved using on E2 (0.015% enzyme); E3 (0.015% phytoadditive) and E4 (0.015% enzyme + 0.015% phytoadditive). The high fibre diets had no negative impact on productive performances and egg quality parameters. Yolk cholesterol significantly decreased (P<0.05) on E1, E3 and E4 groups compared to C, E2 groups. Villi height increased significantly (P<0.05) on E2 group compared to all other groups. In conclusion, the high dietary crude fibre (7%), additional enzymes/phyto additives, can improve the nutrient digestibility and intestinal morphology with beneficial effects on health and egg quality.

“…Fertility and hatchability are two major parameters that highly influence the supply of day-old chicks. Many factors of which nutrition, sex ratio, age, egg weight and storage duration are the most important ones could affect fertility and hatchability of eggs (Praes et al 2014;Uğurlu et al 2017). For the hatchability traits, breed has little effect on hatchability of poultry eggs, although light breeds like White Leghorn have been reported to have high fertility and hatchability (King'ori 2011).…”

The substitution effect of maize grain with grain milling by-products (GMP) was investigated on egg production and fertility parameters in White Leghorn layer hens. To this effect, four treatment (T) diets were formulated to contain GMP (g/kg) at zero (T1), 100 (T2), 150 (T3) and 200 (T4) by partially replacing the maize grain. Onehundred forty four White Leghorn layer hens were allocated randomly to the treatment diets, replicated thrice consisting of 12 hens each. The experiment was conducted for 20 weeks. The results indicated that the hen-housed egg production and daily egg mass output was higher (p<0.001) in hens fed with T1 and T2 diets than those of T3 and T4. Birds fed with T1 diet produced heavier (p<0.001) eggs than those reared in T2, T3 and T4 diets, the former being significantly different with the latter two. The daily feed intake differed significantly among treatment diets being higher (p<0.001) in birds fed with T1 and T2 than that of T3 and T4 diets, which had similar values. No significant difference was observed in hen-housed egg production, daily egg mass output, and daily feed intake among hens fed with T1 and T2 diets. Similarly, no significance difference was observed in egg weight, total and daily feed intake between hens fed with T3 and T4 diets. The feed conversion ratio (FCR, kg feed/kg egg mass) were different among treatment diets in which the lowest value being observed in those chickens reared in T1 followed by T2 diets. Birds fed with T4 diet had the highest FCR as compared with the rest of the treatment groups. Fertility and hatchability of eggs set were similar among chickens reared in T1 and T2 diets; but were higher (p<0.05) than those of T3 and T4 which had similar values. However, hens fed with T4 diet had lower (p<0.05) value in hatchability of fertile eggs than the rest of other treatments. In conclusion, the substitution of maize grain with 10% GMP showed similar effect with that of the control group in all studied performance parameters. Thus, GMP could be safely incorporated in replacement of maize for layer hen diets up to 10%.
