The paper presents the results of evaluating the efficiency of feed rations offered to broilers of the Arbor Acres cross, formed taking into account the climatic, geochemical conditions of Central Africa and its native food flora. The study was conducted on the basis of an experimental farm at the University of N’Djamena, the Republic of Chad. In the experiment, the authors used five formulas of feed rations, which are currently used by farms in the Republic of Chad for growing broiler chickens. They mainly contain locally availble ingredients. To increase the resistance of the poultry organism to unfavorable environmental factors, the chickens of the control and experimental groups were given “TETRACOLIVIT” and “AMIN’TOTAL” vitamins. The efficiency of feed rations was evaluated by determining the age dynamics of live weight, average weekly gains in live weight and blood biochemical parameters of broiler chickens of the Arbor Acres cross from 1 to 42 days of life. The formula of feed ration No. 1 proved to be the most effective in terms of the cross productivity.

Abstract New multiparameter biomechanics models are developed in this work for the characterization of bone strengths in broiler chickens and turkeys, as functions of the major physical and biochemical parameters, which can contribute to mechanical properties of bone strengths in these birds, under good management practices. Theoretical and experimental methods have been developed in this study to model bone strength as functions of (a) the physical parameters only and (b) the biochemical parameters only, which can affect bone strength. The choice of any particular methodology will depend on the availability of either the physical or biochemical parameters, which can be obtained from experimental data. Possible useful practical applications of the statistical biomechanics principles developed in this technical paper, particularly in the field of bone strength enhancement in turkeys and broiler chickens will be discussed. In view of the problems described, the major objectives of the present study are as follows: (1) To develop new multiparameter biomechanics models for the characterization of bone strengths in turkeys and broiler chickens as functions of the major physical only, or biomechanical parameters only, which can contribute to bone strength in these birds, under conditions of good management of these birds. This study will consider only the compressive buckling as the mode of structural failure in the cellular material of the bone. (2) To highlight briefly the possible practical applications of the statistical biomechanics principles, which will be developed in this study to the genetic improvement of bone strengths in broiler chickens and turkeys.

This study investigated the genetic variation in carcass traits and blood parameters of local naked neck and normal-feathered chickens and their crosses with Marshall broiler chickens. Two hundred and sixty three chickens consisting of 50 purebred Marshalls (M), 38 naked neck (Nk) and 48 normal-feathered (N), 61Marshall x naked neck (MNk) and 66Marshall x normal-feathered(MN) chickens were used for the study. Data were collected on carcass traits, haematology and serum biochemical parameters and were analysed using the General Linear Model procedure of Statistical Analysis System. Carcass traits such as eviscerated weight and weights of thigh, drumstick, breast, wings and organs were significantly (P < 0.0001) affected by genotype. Results showed that the purebred Marshall had the highest values in most of the traits followed by their crossbreds. In organs such as gizzard, liver and heart the local normal feathered ranked equal with its crossbred. Sex significantly (P< 0.05) affected carcass traits. Males consistently had higher values than females in all the parameters measured. Genotype significantly (P
