Última Effect of litter treatment on growth performance, intestinal development, and selected cecum microbiota in broiler chickens R. Bras. Zootec. Taherparvar,Gilaneh; Seidavi,Alireza; Asadpour,Leila; Payan-Carreira,Rita; Laudadio,Vito; Tufarelli,Vincenzo. ABSTRACT The objective of this study was to determine whether the type of bedding materials (sand, wood shavings, and paper) and of two chemical amendments (lime and bentonite) could interfere with litter quality (moisture, pH, and total bacterial counts), thereby influencing also the growth performance and the development of intestinal traits and cecum microbiota of chickens. Two hundred and seventy male Ross 308 broiler chickens were randomly assigned into nine treatment groups with three replicates per treatment. Broiler productive parameters, relative weight of different intestinal segments, content of cecal total bacterial counts (total aerobic bacteria, Lactobacilli, and coliforms), as well as litter moisture, pH, and total aerobic bacteria and...

Bras. Zootec. Safari-Aliqiarloo,Abbas; Zare,Masoomeh; Faghih-Mohammadi,Farhang; Seidavi,Alireza; Laudadio,Vito; Selvaggi,Maria; Tufarelli,Vincenzo. ABSTRACT The objective of this study was to analyze the effect of environmental factors on egg production curve traits in broiler breeders. The weekly egg production records of birds collected from four different flocks were used to estimate the egg production curve parameters using the Compartmental function (y = A(1 − exp−b(t − d))exp−ct). The coefficient of determination (R2) obtained by the model was 0.98. Least squares analysis of variance indicated that the environmental factors such as hatchability and flock had significant effects on egg production curve traits. The highest correlation was observed between the weekly potential maximum yield and yield at the beginning of laying, whereas the lowest correlation was found between the weekly potential...
