The study was carried out at the poultry section of the Department of Animal Science farm, University of Education Winneba (Mampong - Ashanti campus, Ghana) from July, 2018 to September, 2018. Data were collected from fifty randomly selected and tagged birds. The data were collected weekly for eight weeks., Head length (HL), Beak length (BL), Body length (BL), Wing length (WL), shank length (SL), shank circumference(SC) and height(H) were taken randomly on five birds in each replicate at a day in every two weeks using tape measure and Vernier calipers. The data collected were analyzed using simple linear regression analysis. The results from the study indicated that, all linear body measurements were significantly (P<0.01) effected for the model, intercepts and slopes of the regression lines with linear response with the best predictor of body weight indicated for shank circumference. It was concluded from the study that; linear body measurements could be used to predict the body weight of broiler chickens. It is recommended that in areas, especially rural areas, where weighing balance or scale may not be readily available, a tailor’s tape can be used to measure linear body parameters and thereafter used to estimate body weight of chickens from the predictive equation.
One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
