This study was carried out to determine the effects of lovastatin supplementation on laying performance, egg quality, yolk lipid profile and some serum parameters in Lohmann LS white commercial laying hens reared in poultry houses of Food and Livestock Application and Research Center of Ataturk University. In this experiment, Lohmann layers (n=48, 46 wks of age) were randomly divided into two groups such as control (C) fed with basal diet and treatment (L) group fed with diet including 0,0059 % of lovastatin. After one week of the adaptation period, experiment lasted for five weeks. During the experimental period, hens were fed as ad-libitum and water through nipples was available for all the times. Lovastatin supplementation increased feed consumption (FC) and feed conversion ratio (FCR). Except for yolk color, other egg quality traits were not affected by diet including 0,0059 % of lovastatin. Hens fed with treatment diet had greater triglyceride and phosphatidyl serine values than hens fed with basal diet. Differences between the groups in terms of the levels of egg yolk and serum cholesterol were not significant in present study. These differences could be attributed to short experimental period and low lovastatin added to basal diet of hens. In conclusion, further studies should be conducted to clarify the effects of lovastatin supplementation on laying performance, egg quality, yolk lipid profile and some serum parameters in laying hens fed with diets including lovastatin at different levels during long feeding period.

This study was carried out to determine the effect of dietary rosehip seed (RS) supplementation into layer diets at different levels on performance, egg quality traits and some serum parameters. A total of 72 Lohmann layers, 46 weeks old, were divided into three treatment groups. The control group was fed with commercial layer diet (K), and the other two groups were fed with basal diet + 10% ground rosehip seeds (K1) and basal diet + 15% ground rosehip seeds (K2) for 12 weeks. The water and feed were provided as ad-libitum during the trial. The rosehip seed supplementation level at 15% into layer diets increased the feed consumption and egg yield (p<0.05), and decreased the damaged egg ratio. Though some egg quality traits such as the yolk colour, shell thickness and shell weight increased (p<0.05) in eggs from K2 group, there were no significant differences (p> 0.05) among the groups in respect to other egg quality traits such as shape index, shell strength, albumen and yolk indexes and Haugh unit values. Total cholesterol, cholesterol esters, free fatty acids and triglyceride contents in the egg yolks from treatment groups were not affected by dietary treatments (p> 0.05). Serum parameters such as albumin, total cholesterol, VLDL, triglyceride and ALT values increased (p <0.05) with the RS supplementation at level of 15% into layer diet. Results showed that rosehip seed supplementation into layer diets may be beneficial to improve egg quality traits especially such as shell thickness and to decrease damaged egg ratio. But further investigations are needed to clarify the use of rosehip seed in layer diets and its effects on performance, egg quality and serum parameters. [ABSTRACT FROM AUTHOR]

This experiment was conducted to investigate the effect of coriander oil supplementation at different levels into diets of laying hens on performance, egg quality traits, yolk thiobarbituric acid reactive substances (TBARS) values and some blood parameters. A total of 96 Lohmann white layers, 24 weeks of age, were used in this study as control and three treatment groups, each containing 24 hens. Control group (K-0) was fed with diet containing a standard commercial layer diet, other treatment groups were fed with diets containing basal diet plus 0.1% (KY-1), 0.3% (KY-2), 0.5% (KY-3) coriander oil, respectively. Experiment lasted for 12 weeks. Performance parameters such as feed intake, feed conversion rate and cracked egg rate were not affected by dietary treatments (P>0.05), but adding coriander oil into layer diets increased egg production and decreased egg weight compared with the control group (P<0.01). Dietary treatment did not affected egg quality traits (P>0.05). While coriander oil supplementation decreased serum cholesterol content, other serum parameters were not affected by dietary treatment (P>0.05). Yolk TBARS values were not differed among the treatment groups (P>0.05) during storage time (0, 7, 14 and 28 days). The storage time of eggs affected TBARS formation (P<0.01) and increased yolk TBARS values significantly in egg stored during 28 days. [ABSTRACT FROM AUTHOR]

Although Turkey is one of the world's most important countries with egg production, total production is not at its current potential. The most effective way to increase total egg production is to increase productivity. In this study, egg production efficiency of rations formed by adding humate to laying hen’s basal diet at various ratios was analyzed using Gamma and McNally models. It was determined that humate added at 0.15% into diet of laying hens gives the maximum contribution to egg production. As a result, it is suggested that further investigations in different regions on different species and breed of poultry are needed to clarify the effect of humate supplemented into diets of laying hen on the egg production.

This study was carried out to determine the mineral substances such as macro and micro minerals of legume and cereal forages grown as naturally in the pastures of Erzurum province. In present study, clover, (Medicago sativa), mountain hispanic sainfoin (Hedysarum elegans), bird vetch (Vicia cracca), hairy vetch (Vicia villosa), mountain vetch (Vicia alpestris), mountain clover (Trifolium montanum), caucasian clover (Trifolium ambiguum), the three-headed clover (Trifolium trichocephalum), tawny grass crown (Coronilla varia), the crown of the eastern horn of grass (Coronilla orientatis) and yellow flowers gazelle (Lotus corniculatus) from legume forages; cocksfoot (Dactylis glomerata), crested wheatgrass (Agropyron cristatum), red fescue (Festuca rubra), sheep ball (Festuca ovina), tawny bromine (Bromus variegatus), blue split (Agropyron intermedium), kelp tail grass (Phleum pratense), meadow bluegrass (Poa pratensis) from cereal forages were investigated. The obtained data were subjected to an analysis of variance by using SPSS 12.0 package program. Significant differences between means were tested by using Duncan’s Multiple Range Test. Macro minerals such as Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg) and Sulfur (S) assigned for legume forages changed between 2.39- 3.30%, 1.16-1.28%, 0.70-2.69%, 0.56-1.61%, 0.11-0.51% and 0.16-0.27%, respectively. The amounts of micro mineral like Iron (Fe), Virgin (Cu), Zinc (Zn), Manganese (Mn) and Boron (B) of legume forages were determined to be 105.9-893.7 ppm, 2.22-12.36 ppm, 14.11-195 ppm, 18.18-66.58 ppm and 5.91-40.39 ppm, respectively. Instances of macro minerals of cereal forages were found for N 1.76-of 2.19%, P 1.10-1.19%, K 1.99-3.25%, Ca 0.09-1.15%, Mg 0.07-0.26% and S 0.22-0.36% in present study. Micro minerals such as Fe, Cu, Zn, Mn and B determined for cereal forages changed between 74.90-630.6 ppm, 4- 9.84 ppm, 31.49-335.6 ppm, 24.63-94.51 ppm and 0.35-26.64 ppm, respectively. In conclusion, present study carried out to determine the macro and micro mineral contents of legume and cereal forages grown as naturally showed that differences in terms of macro and micro minerals among both legume forages and cereal forages were significant.

In this study, the situation of animal husbandry of Erzincan province between the years of 2000 - 2010 were examined, and its problems and proposals for solutions were discussed for the last decade, Some important changes have occurred in point of view of existence of bovine during 2000-2010 in Erzincan province. As compared, the number of total native cattle, buffalo and cattle crossbreeds of province in 2010 years were lower as 51.8%, 52.5% and 11.4% respectively, than those of the 2000 years, On the other hand, the number of pure breeding of cattle increased as 15.8%, according to 2000 years. For the same period mentioned above, the number of total native, buffalo, pure cattle breed and cultural crossbreeds of Erzincan province were respectively 1.62%, 0.8%, 1.5% and 0.9% of Turkey bovine numbers, as proportioned. The vast majority of the existing livestock enterprises in the province of Erzincan is the style of a small family business. Main problems of animal husbandry of the province are related to scanty animal shelters, lack of cultivation, high costs of feeding because of yield losses of pastures, inadequate forage and crops production and uncoordinated agriculture.
