Comparison of different nonlinear functions to describe Nelore cattle growth.
This work aims to compare different nonlinear functions for describing the growth curves of Nelore females. The growth curve parameters, their (co)variance components, and environmental and genetic effects were estimated jointly through a Bayesian hierarchical model. In the first stage of the hierarchy, 4 nonlinear functions were compared: Brody, Von Bertalanffy, Gompertz, and logistic. The ana...
متن کاملGrowth Performance, Carcass Characteristics, Antibody Titer and Blood Parameters in Broiler Chickens Fed Dietary Myrtle (Myrtus communis) Essential Oil as an Alternative to Antibiotic Growth Promoter
This experiment was conducted to determine the effects of Myrtle Essential Oil (MEO) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. A total of 200 Ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...
متن کاملEvaluation of Models to Describe Temporal Growth in Local Chickens of Ghana
The logistic, Gompertz, Richards and asymmetric logistic growth curve models were fitted to body weight data of local Ghanaian chickens and French SASSO T44 chickens. All four growth models provided good fit for each sex by genotype growth data with R2 values ranging from 86.7% to 96.7%. The rate constant parameter, k, ranged between 0.137 and 0.271 and were significantly different from zero fo...
متن کاملA decimal code to describe the growth stages of sesame (Sesamum orientale L.)
A standard description of growth stages for crops/plants is necessary not only for determining and improving cultural practices, but also to facilitate enhanced communication among producers, researchers, and educators. It also could help in unifying experimental results. Many different descriptions of growth stages are currently available for many crops, but there are no codes for sesame (Sesa...
متن کاملPre-Noun Modifiers as a Means to Describe Product Characteristics
The article deals with the characteristics of noun phrases functioning in pre-position. Pre-noun modifiers, or attributive modifiers, are among the high-capacity structures in the contemporary English language, as they enable to devoid of prepositions and to describe objects in a laconic way. The goal of this research was to analyze the way scholars interpret this linguistic structure today, as...
