“…In agreement with the observations of Gordon et al (2009), it became evident from the present results that profits associated with lighter hens like ISA Brown and Sonali were higher than those associated with heavy profitability of lighter hens was hens such as RIR and Cobb 500 and the increased largely due to their improved feed conversion, because lighter hens produced predominantly larger or extra large eggs. Broiler farming with Cobb 500 was reported profitable because of lower investment, less space requirement, utilization of family labour and quick returns as examined by Islam et al (2010).…”

Production performance and economic efficiencies of broiler of Cobb 500, cockerel of ISA Brown, Fayoumi, and RIR (Rhode Island Red) and Sonali (derived from RIR? × Fayoumi?) available in Rajshahi were investigated. Identical care and management practices were provided to chickens of all genetic groups reared for meat and egg production. Performance of four meat purpose chickens viz., Cobb 500, ISA Brown, Fayoumi and Sonali were evaluated in terms of such important parameters as initial body weight (IBW), 5-wk rearing period (RP), achieved body weight (ABW), feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR). Performance of three egg purpose chickens viz. Fayoumi, RIR and Sonali included weight of day-old chick (WDOC), growth rate (GR), death rate (DR), fertility (FR), hatchability (HT), first laying age (FLA) and monthly egg production (MEP). Economic efficiency parameters viz., total cost (TC), gross return (GRR), net return (NR) and cost-benefit ratio (CBR) were calculated for both types. In terms of FI, FCR and BWG values, broiler of Cobb 500 was the best preferred and cockerel of ISA Brown the least preferred chicken. Conversely, in terms of the CBR values for meat producers, the cockerel of ISA White (1.58) was the best and the broiler of Cobb 500 (1.15) the worst. Taking the FLA and MEP into account, RIR topped the list (19.1 wks and 23 eggs per month) whereas Cobb 500 ranked at the bottom (25.2 wks and 16 eggs per month). CBR for egg productivity, on the other hand, was highest in Sonali (1.11) followed by RIR and Fayoumi (1.10 each) and Cobb 500 (1.09). As regards the meat productivity, significant correlations existed between TC and NR for all chickens except Sonali, which exhibited a negative correlation between the traits. Negative and non-significant associations prevailed for egg productivity in all the chickens. Although broiler of Cobb 500 was found to be the most popular for meat and RIR for egg, the cockerel of ISA Brown was the chicken that earned the maximum CBR.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15374Univ. j. zool.

“…Showing an increase of egg mass during the first cycle of molting from the regular production cycle expressed in index points clearly indicates the trend of their increase and shift their weight to heavier classes. The same results were obtained in the research conducted by Gordon et al, 2009. By organizing data obtained from regular production cycle and the first molting process there was noticed very significant differences in the parameters that are logically impose such a conclusion.…”

The method of artificial interruption of the production process by hens, broiler breeders, today known as the molting, it is often used in recent years as one of possible reasonable steps in making decisions on feasibility of continuing exploitation of broiler breeder safter the regular production process. The aim of this study was to test the economic profitability molting hens-broiler, during one exploitation period. It included the throat of hybrid heavy line COBB500. The animals in the house were exposed to the same microclimate conditions, with identical positions in relation to light, ventilation, water, food and fertilization system. The analysis of food consumption per produced egg can be notice that parents' hens during the process of molting consume more food by 43% compared to the hens fed the normal cycle of production. Achieved income was 2.54% higher after billing code for molting chickens instead of the regular production cycle. Economic indicators egg production after molting demonstrate justification of these biological and technological operations, considering that the net income per hen housed is the same income in the normal production process.

“…During the transition phase of the birds from the chicks to the growers (i.e., between week 10 and 12), there was a period of physical adjustment to the new feeds between week 10 and 12. Leeson and Summers [79] and Mwaniki et al [21] revealed that birds are usually physically challenged before the onset of egg laying with great potential for negative nutrient balances to occur. This explains why young birds must be provided with adequate energy and nutrient-rich feeds for proper body build up before the onset of egg laying.…”

Cost-Effectiveness of Black Soldier Fly Larvae Meal as Substitute of Fishmeal in Diets for Layer Chicks and Growers

The acceptance of eco-friendly black soldier fly larvae meal (BSFLM) as sustainable alternative protein ingredient in poultry feeds continues to gain momentum worldwide. This study evaluates the impact of BSFLM in layer chick and grower diets on the growth, carcass quality and economic returns. Mean weekly weight gain and total live weight per chick and grower varied significantly. The highest final weight gain was achieved when birds were provided diet with 25.6% BSFLM. Average daily feed intake (ADFI), average daily weight gain (ADG) and overall weight gain of the chick varied significantly, except for the feed conversion ratio (FCR). For grower birds, ADFI, ADG, FCR and overall weight gain did not vary significantly across the various feeding regimes. The weight of the wings and drumsticks had a quadratic response with a maximum weight obtained at 33% inclusion of BSFLM. The weight of the internal organs were not significantly affected by dietary types. Positive cost–benefit ratio and return on investment was recorded for diet types with higher BSFLM inclusion levels (>75%). Diets with 25% and 100% BSFLM inclusion were the most suitable and cost-effective, respectively. Thus, BSFLM represents a promising alternative source of protein that could be sustainably used in the poultry industries.
