Kanber Kara | Eray Aktuğ | Alper Çağrı | Berrin Kocaoğlu Güçlü | Erol Baytok
In this study, it was aimed to investigate the effects of formic acid on the in vitro methane production and in vitro ruminal fermentation of alfalfa hay. Effect of 0.0 (control group: YF0), 0.1, 0.2, 0.3, 0.4 and 0.5 ml/L (experimental groups: YF1, YF2, YF3, YF4, and YF5 respectively) formic acid (Amasil85-liquid) addition to rumen fluid on ruminal fermentation parameters of alfalfa hay were determined by using in vitro gas production techniques. Methane production of in vitro incubation increased (to about 20%) with addition of linearly increased formic acid. Linearly increased levels of formic acid addition to rumen fluid has significantly changed the production of in vitro total gas production, metabolic energy (ME) and organic matter digestibility (OMD) at linear, quadratic and cubic. The addition of 0.1 ml/L and 0.2 ml/L formic acid to rumen fluid significantly decreased in vitro total gas production, ME and OMD however addition of 0.3 ml/L and 0.4 ml/L formic acid was not changed in vitro gas production, ME and OMD levels and 0.5 ml/L formic acid was significantly increased all these parameters. Ruminal pH was not changed by addition of formic acid. Formic acid is a safe feed additive because of its properties antibacterial and flavorings and also is used as a fermentation promoter in silage. In this study it has been observed that all doses of formic acid increased in vitro enteric methane production and low doses decreased in vitro total gas production, ME and OMD and high doses have increased all these parameters. High doses have a positive effect on ME and OMD; however formic acid should be used at limited levels in diets due to the negative effect of increasing greenhouse gases. The effect of formic acid addition to the feed raw matter and rations of all livestock would be beneficial to investigate in terms of digestive system parameters and global warming, further in vitro and in vivo studies.

Eferhire Aganbi | Oghenetega Jonathan Avwioroko | Emmanuel Rex Enabulele | Onyeka Joshua Osagu | Chinedu Kennis Uwandu | Assumpta Ike | Aaron Akpede | Prince Eferusuoa
The protective effects of ‘ofada’ rice koji (ORK, fermented ofada rice) and ascorbic acid (AA) against lead (Pb)-induced toxicity in the blood, liver and kidney tissues of male Wistar rats was investigated. The animals were divided into four treatment groups (A – D, n = 5). Groups B, C and D were intoxified by intra-peritoneal injection of 75 mg lead acetate/kg body weight. Groups C and D only had their feed mixed with ORK and AA, respectively. The results showed no significant difference in % packed cell volume (PCV) and Pb concentrations. Feeding with ORK and AA significantly decreased alanine aminotransferase activities (36.50 ± 3.54 and 34.02 ± 0.05 UL-1 respectively) compared to Pb-only treated group (85.50 ± 3.25 UL-1). The ferric reducing antioxidant power (FRAP) for organs increased significantly following intake of feeds mixed with ORK and AA; increases in FRAP was higher for ORK-treated group possibly due to increased total flavonoids concentration following fermentation. Furthermore, Pb-induced high plasma creatinine levels decreased upon treatment with feeds mixed with ORK and ascorbic acid. These findings strongly indicated that feed supplementation with ORK by 45% may be more effective at ameliorating the effects of Pb-induced toxicity in tissues compared to supplementation with AA by 2%.

Mehmet Aydoğan | Kürşat Demiryürek | Nur İlkay Abacı
This study was conducted to reveal of future estimation of the dry bean production area, production quantity, export quantity, import quantity and supply-demand balance in Turkey. The data used in the study were obtained from the Turkish Statistical Institute (TIS), FAO and the Ministry of Food Agriculture and Livestock records. The Double exponential smoothing method was used to estimate the future data. The data was used in the analysis includes dry bean production areas (ha), quantity of production, export, import and domestic use between 1994 and 2014. In the next five years (2015-2019), it was forecasted that there would be a decrease in the amount of the dry bean production areas, production quantity and export quantity whereas there would be an increase in the amount of the dry bean import quantity and domestic use. At the same time, it was expected that the amount of dry bean domestic supply would be higher than dry bean domestic demand. The reason for this surplus is high import quantity. In other words, it was foreseen that Turkey’s external dependence in dry bean will increase. In order to ensure continuity of production, it should be increase the income of dry bean producers, decrease the dry bean production cost and encourage the production. The policies to prevent domestic prices fall should be developed.

In this study, examined the structure and problems of fruit sapling producing enterprises and offers solutions in The Hatay Province. The data were obtained from 92 enterprises by the method of full count and face to face with producers. Of the 51.15% population in creating family business primary school graduates, the proportion of university graduates remained at 8.62%. The rate of agricultural engineer employment in the businesses is 2.18%. While 64.05% of the enterprisers the father's profession, this profession began taking 3.37's% of nursery education. Average potential family labour is the 4.22 male labour forces in enterprises. The family labour utilization rate was calculated as 50.71%. Of the 88.48% in fruit sapling businesses, 5.32's% in other agricultural productions and 5.22's% in non-agricultural jobs of total used men workforce. The businesses have average total land size of 25.74 acres which it has established 12 acres of fruit sapling production land. While 74.58% of the total fruit sapling land is property, 25.42's% is for rent situation. The operating capital is calculated as the average of 229.308 TL. The most common species of fruit sapling production were citrus (46.20%) and olive trees (35.29%). The problems faced by most of the farms in the region were high input prices, excessive bureaucratic procedures preventing memberships into the union, an inadequate amount of support provided by the state, production-threatening diseases of plants and difficulties in finding qualified staff in the region. The results show that enterprises need to increase their production capacity, to unite under one organization to facilitate the resolution of problems.
Afficher plus [+] Moins [-]Evaluation of Multiple Imputation in Missing Data Analysis: An Application on Repeated Measurement Data in Animal Science
2015
Gazel Ser | Cafer Tayyar Bati
The purpose of this study was to evaluate the performance of multiple imputation method in case that missing observation structure is at random and completely at random from the approach of general linear mixed model. The application data of study was consisted of a total 77 heads of Norduz ram lambs at 7 months of age. After slaughtering, pH values measured at five different time points were determined as dependent variable. In addition, hot carcass weight, muscle glycogen level and fasting durations were included as independent variables in the model. In the dependent variable without missing observation, two missing observation structures including Missing Completely at Random (MCAR) and Missing at Random (MAR) were created by deleting the observations at certain rations (10% and 25%). After that, in data sets that have missing observation structure, complete data sets were obtained using MI (multiple imputation). The results obtained by applying general linear mixed model to the data sets that were completed using MI method were compared to the results regarding complete data. In the mixed model which was applied to the complete data and MI data sets, results whose covariance structures were the same and parameter estimations and standard estimations were rather close to the complete data are obtained. As a result, in this study, it was ensured that reliable information was obtained in mixed model in case of choosing MI as imputation method in missing observation structure and rates of both cases.
Afficher plus [+] Moins [-]Effect of Replacing Beef Fat with Chicken Skin on Some Properties of Model System Chicken Emulsions
2015
Aslı Zungur | Berker Nacak | Meltem Serdaroglu
Model system chicken emulsions were prepared by replacing 5, 10, 15 and 20 % beef fat with chicken skin. Moisture, protein, fat, ash and pH were determined in raw and heat processed emulsions. Emulsion samples were evaluated for cooking characteristics, TBA values and colour parameters (L*, a*, b*). Addition of chicken skin decreased fat content and increased moisture and protein content of emulsion samples. Chicken skin replacement significantly increased water holding capacity and cooking yield and decreased fluid release. Increasing chicken skin in formulation increased a* and b* values of emulsion samples. Therefore, adding of chicken skin instead of beef fat is useful in improving technological quality and producing low fat formulation.
