Modelación del crecimiento de aves Criollas Mexicanas, Rhode Island Red y Hy-Line Brown

نویسندگان

چکیده

El objetivo fue caracterizar el crecimiento de aves Criollas Mexicanas (CMX), Hy-Line Brown (HLB) y Rhode Island Red (RIR) mediante los modelos Gompertz-Laird (MNGL), Logístico (MNL), Richards (MNR) Von Bertalanffy(MNVB). Se utilizaron 70 pollitas cada genotipo. Cada ave identificada para registrar su peso 7 a 210 d edad. Los parámetros se estimaron con procedimiento NLIN (algoritmo Marquardt) SAS. calculó coeficiente determinación ajustado, criterio información Akaike Bayesiana, caso. La tasa inicial (d−1) en CMX menor (0.047 15) que RIR (0.071 69) HLB (0.052 16). Con cuatro modelos, la decaimiento menor, respecto otros genotipos. Asimismo, edad al máximo (d) las CMX,RIR HLB, varió 49.4 87.9, 60.7 81.6 58.7 87.8, respectivamente. Por otro lado, asintótico (g), estimado 2 068.5 644.3, 1 902.4 250.9 096.3 464.5, CMX, MNVB obtuvo mejor ajuste datos contraste, MNR seguido del MNVB. sería más adecuado estudio simultáneo HLB.

This paper describes MEDUSA, an experimental algorithm synthesizer. MEDUSA is characterized by its top-down approach, its use of cost-constraints, and its restricted number of synthesis methods. Given this model, we discuss heuristics used to keep this process from being unbounded search through the solution space. The results indicate that the performance criteria can be used effectively to he...

Estimating microsatellite based genetic diversity in Rhode Island Red chicken

This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIRS and control line RIRC) of Rhode Island Red (RIR) chicken. Genomic DNA of 24 randomly selected birds maintained at Central Avian Research Institute (India) and 24 microsatellite markers were used. Microsatellite alleles were determined on 6% urea-PAGE, recorded using GelDoc system and the samples ...

In this article a computational model for the interpolation and exploration of Complex Response Surfaces is described and analyzed. This computational model consists of two stages: an initial stage in which a group of points is interpolated by means of the coalition of a series of characteristic concepts of vector geometry, the numeric methods and the evolutionary computation to construct the r...

Abstract There are many possibilities to design a parallel program in order to obtain the best performance possible. The selection of a program structure, as an organisation of processes, impacts on the performance to be achieved, and depends on the problem to be solved. Now, in order to select a program structure as the best in terms of performance, the software designer requires performance m...

Genetics of Body Conformation and Feed Efficiency Characteristics in a Control Line of Rhode Island Red Chicken

This investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of Rhode Island Red (RIR) chicken taking single hatched out pedigreed 100 chicks at Central Avian Research Institute, Izatnagar, India. Data was analyzed by least squares analysis of variance. Least squares means of chick weight (CW), body weight (BW), shank length (SL), keel length (KL...
