Öğe Determination of quality and nutrient content of artichoke by-products ensilaged with barley and molasses(Kielanowski Inst Animal Physiology Nutrition, 2023) Demirci, M.; Kara, K.; Karsli, M. A.The aim of this study was to determine the nutrient composition and quality of artichoke by-products ensiled with barley and molasses. Artichoke by-products included leaf, bracts and stalks of plants. Materials for ensiling were prepared from artichoke by-products without any additives (control silage), or with barley and molasses in the amounts of 2.5% and 5%, respectively. The prepared materials were ensiled in jars, incubated, and then the nutrient contents, selected fermentation parameters, and in vitro dry matter digestibility (IVDMD) of these silage samples were determined. Barley and molasses supplementation increased dry matter, organic matter, IVDMD, pH, lactic and acetic acid values of the silage from artichoke by-products (P < 0.05). However, the content of crude protein, ash, neutral detergent fibre and acid detergent fibre decreased in artichoke by-product silage due to barley and molasses supplementation (P < 0.05). In addition, it was determined that propionic acid and ammonia-N levels were similar between the groups (P > 0.05), but butyric acid did not occur at all. In vitro ruminal energy (metabolisable energy and net energy lactation) and IVDMD values of artichoke by-product silages with additives were higher than those of the control silage. As a result, it has been concluded that it is possible to produce similar silages to maize silage from green/fresh artichoke by-products in terms of both organoleptic properties and nutrient content. Moreover, it was also observed that supplementing the silage material with barley and molasses additives significantly improved silage quality.Öğe Determining the effects of black cumin seed oil on performance and meat fatty acid profile of broiler chickens(South African Journal Of Animal Sciences, 2019) Demirci, M.; Karsli, M. A.; Aluc, Y.This study was designed to investigate the effects of adding black cumin (Nigella sativa L.) seed (BCS) oil to diets for broiler chickens on their performance and the meat fatty acid profile of the meat. Broiler chicks were assigned to three groups. The unsupplemented control did not receive BCS oil. The two treated groups received 0.5% and 1% BCS oil. The live weight and live weight gain of the experimental groups were generally greater for the treated groups than for the control group. Feed consumption did not differ among groups, and thus the group that was fed the diet supplemented with 1% BCS oil was most efficient. Total saturated fatty acids were lower, and polyunsaturated fatty acids were greater in the treated groups, but monounsaturated fatty acids were greater in meat from the control group. As a result, it can be concluded that the addition of 0.5-1% BCS oil into the diets of broiler may improve the performance of chicks and enrich the meat quality by creating meaningful changes in meat fatty acid profiles, especially in terms of total polyunsaturated fatty acids.Öğe Digestibility and Silage Quality of Potato Pulp Silages Prepared with Different Feedstuff(Hellenic Veterinary Medical Soc, 2021) Senyuz, H. H.; Karsli, M. A.The objective of this study was to determine silage quality and digestibility of potato pulp ensiled with different feedstuffs (straw, alfalfa hay and wheat bran). A total of 5 different potato pulp silages (PPS) were prepared with 5% ground barley straw, ground alfalfa hay, wheat bran alone or combination of 2.5 % wheat bran+ground straw, and wheat bran+ground alfalfa hay on a fed basis.These silages were ensiled in 2-L jars. After 49d of ensiling, all silages were opened and the chemical composition, pH, organic acids, ammonia-N contents, in situ organic matter (OM) and starch degradabilities and in vitro OM digestibility (IVOMD) of the silages were determined. Then, energy values were calculated.The highest dry matter (DM) and OM concentrations were observed in PPS prepared with wheat bran alone (P<0.05). Potato pulp silage containing ground barley straw alone had the lowest crude protein (CP) concentration (P<0.05) and silage containing wheat bran alone had the lowest neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations among PPS (P<0.05). Potato pulp with wheat bran alone had the highest lactic acid concentrations among all silages (P<0.05). Acetic acid concentrations of silages were similar (P>0.05). The in situ OM degradability and IVOMD were significantly different (P<0.05) among all silages. However, in situ starch digestibility was similar among PPS (P>0.05). It can be concluded that PPS prepared with different feedstuffs at a 5% level had good fermentation properties and high degradability values. Even a high quality PPS can be obtained with the addition of 5% ground barley straw alone.Öğe Effect of substituting barley grain with wet sugar beet pulp silage on some blood metabolites in lambs(Agricultural Research Communication Centre, 2019) Aldemiri, R.; Bingol, N. T.; Karsli, M. A.; Dede, S.The objective of this experiment was to evaluate the effects of substituting grain barley with we sugar beet pulp (WSBP) silage prepared with wheat bran (WSBPS) at different levels on some blood parameters of lambs. A barley grain based control diet was prepared. Then, three experimental diets were prepared by substituting 35, 70 and 100% of barley grain with WSBPS (35, 70 and 100% WSBPS diets). Moreover, negative control was also established. A total of sixty, 6-7 month old male Akkaraman lambs with 24.29+1.50 kg mean body weight were used in the study. These lambs were fed one of five diets for a period of 75 days. Blood samples were taken at the beginning and end of the experiment. Serum glucose, total protein, BUN, phosphorus, and calcium levels were determined. Serum BUN and phosphorus levels were similar at the beginning and end of the experiment (P>0,05). Serum glucose levels were significantly higher in control, 100% WSBPS and negative control whereas Ca level was higher in all groups, except negative control at the end of experiment (P<0,05). Total protein levels were significantly lower in 70 and 100% WSBPS (P<0,05). All of the parameters, except BUN level were statistically similar among groups at the end of the experiment. In conclusion, substituting barley with wet sugar beet pulp silage did not have significant effects on blood parameters, except BUN. Substituting barley with WSBPS could be an alternative feeding strategy for farmers without affecting animal health based on the results of this experiment.Öğe Effects of Plantago major extract on serum levels of antioxidant vitamins and minerals in broiler(Agricultural Research Communication Centre, 2018) Dede, S.; Bingol, N. T.; Kilinc, D. Kilicalp; Deger, Y.; Yoruk, I. H.; Ekici, P. Tanritanir; Karsli, M. A.The aim of this study was to evaluate the effects of Plantago major liquid extract on serum antioxidant vitamin and mineral concentrations of broiler. The experiment consisted of the control and 2 treatment groups, composed of 28 Ross 308 broiler chicks (Total, 84). A basal (control) diet was formulated. P Major was added to the control diet as following: PM1 (5 g/kg feed), PM2 (10 g/kg feed). The chicks were feed for 42 days ad libitum. The serum micronutrients (Retinol, alpha-tocopherol, vitamin D, calcium, magnesium, iron, manganese, and zinc) levels were determined. The retinol, alpha-tocopherol, Fe, Mg, Mn levels were not affected, and the Zn levels decreased in the PM1 and PM2. The supplementation of P. major has affected the serum vitamin D and Zn levels for this study, and should be analyzed for the alterations on the metabolism in subsequent studies.Öğe Effects of the Replacement of Soybean Meal with Pea as Dietary Protein Source on the Serum Protein Fractions of Broilers(Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2016) Bingol, N. T.; Dede, S.; Karsli, M. A.; Deger, Y.; Kilinc, Kilicalp D.; Cetin, S.The aim of this study was to determine the effects of the replacement of different levels of protein derived from soybean meal with that from peas in broiler diets on serum protein fractions. A corn-soybean meal basal diet was formulated as the control diet (Control=C) (NRC, 1994), and then pea was added to the control diet to replace 20% (P20) or 40% (P40) of the crude protein of the control diet. The diets were randomly fed to 12 pens per treatment, each housing five birds, for 42 days. Blood samples were collected from 36 birds (3 birds x 4 pens x3 treatments) and the serum protein fractions were separated. Gamma-globulin percentage was higher in group P20 compared with C and P40 groups. Total protein, beta-globulin, and gamma-globulin concentrations were significantly higher in group P20 compared with those of both control and P40 group (p<0.05).
