| Because of the relatively long growing cycle and the high cost of research into turkey production and nutrition, the potential benefits from modelling growth in this avian species are considerable. Though there are many studies aimed at evaluating animal growth models, the number of studies targeting growth models in turkeys is quite limited. In this paper we present a sinusoidal function to describe the evolution of growth in turkeys as a function of time based on data published by Aviagen. The new function was evaluated with regard to its ability to describe the relationship between body weight and age in turkeys and was compared to four standard growth functions: the Gompertz, logistic, Lopez, and Richards. The results of this study show that the new... |

| Los objetivos del estudio fueron conocer el manejo, los usos y las características fenotípicas de los pavos en la comunidad indígena de Kapola. La metodología se basó en la aplicación de un cuestionario mediante entrevista personal a todos aquellos habitantes que tuvieran pavos en edad reproductiva (N═40 familias) así como en la caracterización de aquellas variables referidas en los descriptores de la FAO para especies avícolas. Los resultados indican que el uso principal de los pavos en la comunidad de Kapola es para establecer una distinción en las relaciones sociales dentro de las fiestas tradicionales; como elemento de ahorro y como ingrediente dentro de la dieta. El manejo es elemental y consiste en alimentarlos a base de maíz, masa, nixtamal y... |

| This paper examines the industrialization process of U.S. agriculture by examining the trends in the number of farms, the concentration of production during the last decade, and the dynamics of farm survivability, entry, and exit underlying aggregate statistics. We next examine vertical coordination as part of the industrialization process and highlight contracting in the poultry industry. The analysis provides evidence that production is continuing to be concentrated on a smaller number of farms at a relatively rapid rate, in spite of the stability in the number of farms. Although contracting clearly dominates the broiler industry, it is less prevalent in egg and turkey production, where other forms of vertical coordination are likely established. |

| A digestibility trial with 16 to 21-day-old turkeys was conducted to study the effects of feed form and corn particle size on the coefficient of total intestinal tract apparent digestibility of dry matter (DM), nitrogen (N), ether extract (EE), aparent metabolizable energy (AME) and aparent metabolizable energy corrected by nitrogen balance (AMEn). A completely randomized experimental design in a 2 × 3 factorial arrangement - two feed forms (crumble and micropellet) and three average particle sizes of the corn (380, 606, 806 µm) - was applied. Three hundred and sixty 1-d-old B.U.T 9 male turkey poults were distributed into 36 cages, 6 replications of 10 birds, each one per treatment. Overall care of birds complied with welfare directive from the... |

| ABSTRACT The physical, morphological, and mechanical characteristics of eggs play an important role in the processes of embryo development and hatching. Some physical, morphological, and mechanical characteristics of turkey (Meleagris gallopavo; Zagorje breed) eggs collected during two laying cycles from same turkey hens were determined in this study. The average values of length, width, geometric mean diameter, weight, surface area, volume, sphericity, eggshell thickness, and eggshell density were determined as 66.61 mm, 46.84 mm, 52.66 mm, 77.74 g, 8712.42 mm2, 76553.49 mm3, 79.31%, 0.354 mm and 3.13 g cm-3, respectively. Eggs collected during second laying cycle were, on average, larger and heavier in comparison with those collected during first cycle.... |

| ABSTRACT The aim of study was to determine the impact of a probiotic preparation containing live bacteria Bacillus cereus var. toyoi on the performance of turkeys in order to define the effective dose of the preparation and to evaluate its influence on poults' livability in the first month of life. Three hundred and sixty B.U.T. 9 male turkey were divided into three groups. The control group (I) was fed a diet with no probiotic additive, and groups II and III were given a probiotic product containing 0.2x109 and 1x109 B. toyoi CFU/kg of feed respectively. Body weight was recorded in weeks 1, 6, and 18. Livability, feed conversion ratio, and European Efficiency Factor (EEF) were estimated. In experiment II, the impact of a standardized probiotic dose on... |
