1. Effect of dietary fat level and source on performance and immune system response of turkeys
ABSTRACT. An experiment was conducted to determine effects of different levels and sources of fats in diets on growth performance, carcass characteristics and immune response of turkeys during four periods (0-21, 22 to 42, 43 to 63 and 64 to 70 days of age). A completely randomized design with five treatments, six replicates and eight B.U.T.6 turkey chickens

2. Macroscopic embryonic development of Guinea fowl compared to other domestic bird species
ABSTRACT Since few studies have addressed the embryonic development of Guinea fowl (Numida meleagris), the objective of the present study was to evaluate its embryonic development in the Cerrado region of Brazil and compare the results to published descriptions of the embryonic development of other domestic bird species. The commercialized weight for Guinea

3. A sinusoidal equation as an alternative to classical growth functions to describe growth profiles in turkeys
ABSTRACT. 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 th

4. Analysis of Variables Affecting Carcass Weight of White Turkeys by Regression Analysis Based on Factor Analysis Scores and Ridge Regression
ABSTRACT In this study, the influence of carcass parts weights (thigh, breast, wing, back weight, gizzard, heart, and feet) on whole carcass weight of white turkeys (Big-6) was analyzed by regression analysis based on ridge regression and factor analysis scores. For this purpose, a total of 30 turkey carcasses of 15 males and 15 females with 17 weeks of age,

5. The Effect of Lentil-By Product on Growth Performance and Carcass Traits of Heavy White Turkeys
ABSTRACT The subject of this study was to figure out the effects of lentil by product (LP) on growth performance and carcass traits of the white heavy turkeys. To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1st, 2nd, 3rd, 4th, 5th, 6th and 7th groups received 0,

6. Use of Organic Acids and A Competitive Exclusion Product as Growth Promoter and Salmonella Enteritidis Control in Commercial Turkeys
ABSTRACT It is estimated that Salmonella causes one million illnesses in the United States annually, with 19,000 hospitalizations and 380 deaths. There are various serotypes of this bacterium, and the serotypes Typhimurium and Enteritidis are commonly isolated from outbreaks and, in most cases, present resistance to the antibiotics utilized in clinical medic

7. Genetic variation of the bronze locus (MC1R) in turkeys from Southern Brazil
Abstract Domestic turkeys present several color phenotypes controlled by at least five genetic loci, but only one of these has been identified precisely: the bronze locus, which turned out to be the melanocortin-1 receptor (MC1R) gene. MC1R variation is important for breeders interested in maintaining or developing different color varieties. In this study, w

8. Non-Linear Model to Describe Growth Curves of Commercial Turkey in the Tropics of Mexico
ABSTRACT The objective of this study was to select the best non-linear model that fits the growth curve of turkeys managed under the tropical conditions of Southern Mexico. Data from 481 Hybrid converter turkeys (236 females and 245 males) reared under commercial conditions typical of that region were used. Turkeys were given ad libitum access to feed and wa

9. Effects of Different Amounts of Blue Lupine (L. Angustifolius L.) in The Diets of Heavy-Type Turkeys on Their Growth Rate, Carcass and Meat Qualities
ABSTRACT A study was carried out to determine the effects of soybean meal replacement with different amounts of blue lupine in the diets of turkeys on the growth rate, anatomic carcass dissection data, chemical indicators of breast and thigh muscles and the content of tryptophan and oxyprolin. In total three hundred and sixty cross BIG-6 turkeys were allotte

10. Analyzing Growth Curves of Turkeys Reared in Different Breeding Systems (Intensive and Free-Range) with some Nonlinear Models
ABSTRACT The objective of this study was to identify the growth curve of live weight of turkeys reared in different systems (intensive and free- range) with the best mathematical model. To achieve this goal, the live weight of male and female turkeys (Large White) reared for 0-18 weeks were used. Logistic, Gompertz, Von Bertalanffy, and Gauss were used to de

11. Ultrastructural Assessment of the Integrity of the enteric Mucosa of Commercial Turkeys Vaccinated against Coccidiosis
ABSTRACT The objective of this study was evaluated the villus integrity of commercial turkeys submitted to coccidiosis prevention methods and challenged with Eimeria field oocysts, using scanning electron microscopy. Sixty BUT 9 female commercial turkeys were distributed in a completely randomized block design split with two treatments: T1- control diet with

12. Proposal of a Standard for the Condemnation for Turkey Carcasses Due to Fowlpox
ABSTRACT This study aimed at proposing a new technical criteria for condemnation of turkey carcasses due to fowlpox in turkeys as a contribution for the work of the Brazilian Federal Meat Inspection Service. Skin samples from 30 carcasses of a flock of 840 turkeys (Meleagris gallopavo), previously vaccinated for fowlpox and slaughtered in June 2013, were col
