A Quantitative Model To Determine Factors Affecting Profits Of Broiler Enterprises, Yavuz Cevger, Cengi̇z Yalçin Jan 2003

A Quantitative Model To Determine Factors Affecting Profits Of Broiler Enterprises, Yavuz Cevger, Cengi̇z Yalçin

Turkish Journal of Veterinary & Animal Sciences

The purpose of this study was to demonstrate the use of the profit function regression model as a decision support tool in commercial broiler production. The fact that the estimated impact factors affecting profitability on the profit per kg live-weight were similar to those observed in the field indicates the power of the model as a decision support tool in broiler production. Because the marginal impact of each independent variable on profit was the estimated coefficient value, they could simply be used to evaluate "what-if scenarios" and the risk of investment under changing circumstances in broiler production. It is, therefore, …

Turkish Journal of Veterinary & Animal Sciences

The possible pharmacological and toxicological effects of Pistacia terebinthus L. in experimentally hypercholesterolemic rabbits were investigated in this study. A total of 28 rabbits were divided into four groups, and these groups were fed diets containing standard pellets (Group 1), cholesterol (2%) (Group II), P. terebinthus L. (1 g/kg body weight) and cholesterol (2%) (Group III) and P. terebinthus L. (1 g/kg body weight) (Group IV) for 14 weeks. When the data were statistically evaluated over the weeks, body weight gains, showed no marked difference among the groups although liver weight was 58% higher in the cholesterol control group (P < 0.01) and 20.3% higher in P. terebinthus L. and cholesterol group than in the control group. In the comparison of the cholesterol-fed groups, Group III exhibited a marked decrease (P < 0.01) in total cholesterol and triglyceride evels and very low density lipoprotein (VLDL) and low density lipoprotein (LDL) levels by the 14th week and a 1.3-times higher (P < 0.001) high density lipoprotein (HDL) value. In the group fed cholesterol and P. terebinthus L., clotting and bleeding times increased by 13% and 12%, respectively, compored to the cholesterol control group. On account of the histopathological findings, it was confirmed that P. terebinthus L. restrained the progression of the atherosclerotic lesions in the thoracic artery and of hydropic degeneration and fatty changes in the liver. No toxic effect could be attributed to P. terebinthus L. from an investigation of the biochemical data. The results of this study show that P. terebinthus L. has a hypolipidemic effect in hypercholesterolemic rabbits.

The Effect Of Different Rations On Some Rumen Fluid And Blood Parameters In Sheep, Taylan Aksu, Suphi̇ Deni̇z

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of different combinations of energy (barley and dried molassed sugar beet pulp (DMSBP)) and protein sources (soybean meal (SBM), cotton-seed meal (CSM), SBM-treated with formaldehyde (FTSBM), CSM-treated with formaldehyde (FTCSM), and urea) on some rumen fluid and blood parameters. In this study, four rumen fistulated Morkaraman rams were used. Rumen pH values were around the optimal pH values suggested for rumen fluid (5.2-7.3) at all sampling times. Ruminal NH_3-N concentrations were significantly greater (P < 0.05) in animals fed DMSBP as an energy source compared with animals fed barley as an energy source and were between 10.4 and 32.75 mg/100 ml in all groups. Formaldehyde treatments of protein sources reduced ruminal NH_3-N concentrations in animals fed DSBP as an energy source (P < 0.05). Acetic and propionic acid concentrations were affected by the energy source, although butyric acid concentrations were significantly higher in animals fed groups containing barley than in animals fed groups containing DMSBP. Formaldehyde treatment did not affect propionic acid concentrations, although propionic acid concentrations were generally significantly higher (P < 0.05) in animals fed barley + SBM combinations compared to treatments containing both SBM and CSM combinations (P < 0.05). Serum total protein concentrations were affected by the energy source and these were higher in groups containing DMSBP than in groups containing barley (P < 0.05). However, serum urea-N concentrations were similar among the different diets.

The Taxonomy And Distribution Of Apodemus Agrarius (Pallas, 1771) (Mammalia: Rodentia) In The European Part Of Turkey, Haluk Kefeli̇oğlu, Coşkun Tez, İslam Gündüz

Turkish Journal of Zoology

The morphological and karyological characteristics of 27 specimens of Apodemus agrarius (Pallas, 1771) from the European part of Turkey were studied in detail and compared with those in the literature in order to provide a wider perspective on the taxonomic status of Apodemus agrarius in Turkey. In all the samples examined, 2n = 48 karyotype was observed with FN = 56 and FNa = 54. The 2n = 48 karyotype includes three pairs of metacentric, one pair of submetacentric and 19 pairs of acrocentric autosomes. Of the sex chromosomes, the X is a large acrocentric and the Y is a …

Population Dynamics Of Soft-Furred Field Rat, Millardia Meltada, In Rice And Wheat Fields In Central Punjab, Pakistan, Shaher Bano Lathiya, Abdul Rauf Khokhar, Syed Muzaffar Ahmed

Turkish Journal of Zoology

Data on the abundance, reproduction, diet and damage index of the soft-furred field rat Millardia meltada were collected during the rice and wheat seasons. The abundance of Millardia meltada remained high at the post-harvest stage of the rice and wheat crops. The ploughing of fields did not affect the abundance of Millardia. The mean annual prevalence of pregnancy was 50% and the mean embryonic litter size 6.2 ± 0.4. Millardia continued to eat wheat and rice grains over a long period even when there was no crop standing in the fields. The damage indices in rice and wheat crops were …

Alteration Of Soil Water Content Consequent To Root-Pruning At A Windbreak/Crop Interface In Nebraska, Usa, Qingjiang Hou, James R. Brandle, Kenneth Hubbard, Michele Schoneberger, Carlos Nieto, Charles A. Francis Jan 2003

Alteration Of Soil Water Content Consequent To Root-Pruning At A Windbreak/Crop Interface In Nebraska, Usa, Qingjiang Hou, James R. Brandle, Kenneth Hubbard, Michele Schoneberger, Carlos Nieto, Charles A. Francis

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Root-pruning is generally recommended as an appropriate treatment to reduce competition for soil water and/or nutrients and suppression of crop yield in areas adjacent to windbreaks. Several recent studies suggest, however, that factors other than soil water might be causing yield reduction at the interface. For two consecutive years, we evaluated root-pruning effects on soil water at the windbreak/crop interface under both cropped (soybean [Glycine max (L) Merr.] variety ‘Iroquois’, 1997) and non-cropped (1998) conditions in Mead, Nebraska, USA. Volumetric soil water content near the windbreaks was systematically measured at various soil depths, distances from the windbreak, …
