Canul-Solís d. Reno, Nevada. The main objective was to develop equations to predict body weight BW using heart girth Eqkation in Pelibuey ewes. A second objective was eegression evaluate this model for how to use the regression equation to predict using an independent dataset. For model develop a data set composed byyr-old, non-pregnant and non-lactating ewes; with a mean BW of A second data set composed by 67 animals, with similar characteristics BW of The MEF has indicated a higher efficiency of prediction with higher proportion of the total variance of the observed values been explained by the predicted regresxion 0.

The partition of the MSEP has indicated a very small mean bias 0. The how to use the regression equation to predict bias has shown that preeict how to use the regression equation to predict. The proposed equation accurately and precisely estimated the BW of non-pregnant and non-lactating Pelibuey ewe using HG and therefore is recommended to be used. Un segundo objetivo fue evaluar este modelo para determinar la precisión utilizando un conjunto de datos independiente.

Para desarrollar el modelo, se utilizó un conjunto de datos compuesto por ovejas de años de edad, no gestantes y no lactantes, con una media de peso corporal de Un segundo conjunto de datos compuesto por 67 animales con características similares PC de El MEF ha indicado una mayor eficiencia de predicción con una mayor proporción de la varianza total de los valores observados explicada por los datos previstos 0.

Body weight BW is one of the most accurate measurements to determine livestock growth 1. The further understanding of body growth allows for novel diet optimization approaches with consequences on the improvement of regresslon of sales prices 2as well as management strategies that can improve therapeutic treatments for livestock diseases 23.

Despite of BW being an important economic trait usse can assist feeding and management decision supports; small producers can rarely afford expensive scales necessary to perform such measurement 3which statement is true of the relationship between risk and return quizlet5. Recently, it has been reported that the sheep lose a significant amount of BW over a short-term delay prior to weighing as a result of handling operations leading to losses around to 1.

Therefore, it is important preduct develop alternative practical methods that are of rregression cost and ease allowing smallholders to monitor the body growth of production animals 46. Among alternative method, the use of biometric measurements BM such as the heart girth HGbody length BL and withers height WH are valuable and rather simple tools used for the estimation of the BW of production animals 5. Regresxion HG is highly correlated with the BW of small ruminants sheep and goats of different breeds and therefore is used more frequently 6 - hoq.

Despite of agreements on the correlations of both variables, there are prredict studies under field conditions designed to evaluate the relationship between BW and HG in Pelibuey sheep. Moreover, the predictive equations reported for small ruminants have rarely been evaluated for Pelibuey sheep. The main objective of current study was to develop equations to predict body weight BW using heart girth HG in non-pregnant and non-lactating Pelibuey ewes.

All procedures involving animals were conducted within the guidelines of official techniques of animal care and health in México NOMZOO A data set composed byof 2 to 3-yr-old, non-pregnant and non-lactating, clinically healthy Pelibuey ewes; with a mean Regresssion of A second data set composed by 67 animals, with similar characteristics and mean BW of According to the management of the farm, the ewes were how to use the regression equation to predict in confinement open-sided facilities provided with a roof and concrete floor.

The dietary ingredients were composed of cereal grains corn or sorghumsoybean meal, tropical grasses hay, vitamins, and minerals. Statistical analyses were performed using SAS Outliers were tested by plotting the studentized residual against the regressiion model-predicted values. The goodness-of-fit of the regression was assessed by the root of the mean square error RMSE and the r 2.

The mean bias MBwas used as representation of the average inaccuracy of the model The coefficient of model determination CD was used to assess the variance of the predicted data. The bias correction factor Cba component of the concordance correlation coefficient CCC 18was used as an indicator of the deviation from the identity line, whereas CCC as the reproducibility index simultaneously accounting for accuracy and precision. It was observed that the BW of ewes, ranged from Hoq correlation coefficient r between BW and HG was 0.

The MEF have indicated a higher efficiency of prediction with higher proportion of the total variance of the observed values been explained by the predicted data 0. Table 2 Mean and descriptive statistics of the accuracy and precision of the relationship among observed and predicted values for body weight using the heart girth in Pelibuey ewes.

Figure 1 Relationships between observed and predicted BW using eqjation HG in non-pregnant and non-lactating Pelibuey ewes. The How to use the regression equation to predict indicated medium to low variability in the predicted data 1. The current study presents an evaluation of the practicality of use predixt HG to predict BW of Pelibuey ewes. Although, some articles have been published on this topic in other species and in other sheep breeds; in Pelibuey ewes, there are no reports that evaluate this relationship under field conditions.

Moreover, it has been reported that this type of models should be developed for each breed under the conditions of handling and system of production On the other equattion, the use of empirical equations developed for the prediction of BW and productive performance, among others, is limited by the lack of evaluation of its predictive capacity with independent data that were used for its development, which makes it difficult to ascertain its accuracy and precision It is in agreement with other authors, indicating that this BM is highly correlated with the BW for different animal species 8.

This coincides with the results obtained in how to use the regression equation to predict study using sheep The small variance surrounding the slope of the proposed equation indicates that BW can be explained by the variance of Yse. The HG itself contributes to eqution body area where most of organs are housed. It seems that the thoracic circumference of Pelibuey ewe play a bigger role on the determination of BW than body length.

The practical implications are that the volume and weight of organs housed in the abdominal cavity may represent better determinants on body mass which determines hhe bulk of nutrient requirements of maintenance In addition, Kunene et al 3 reported that the relationship between HG and BW had significant r-values that ranged from 0. Furthermore, Souza et al 23 concluded that the equations generated using the heart girth and body length can be used to estimate the body weight of male and female meat-type sheep of different breeds and ages.

This it agrees with several authors who have reported the importance th HG in BW estimation in sheep of different breeds 7regresdion On the other hand, in the literature, exist different approaches and techniques to evaluate models, according to Mayer and Butler 17the main evaluation techniques are based on subjective assessment, comparative ewuation, measures of deviation based on the differences between observed and predicted values and statistical tests.

In the present signs he just wants a casual relationship, were used the tests and analysis of Model Evaluation Regreseion described by Tedeschi The CD found in the present study was 1. Based on the results of the statistical evaluations, the proposed model predicts the in non-pregnant and non-lactating Regreszion ewes with good precision and accuracy.

For Tedeschi 14the assessment of the adequacy of a model is only what is tuple in dbms mcq through a combination of statistical analysis according to the purpose for which the model was conceptualized and eqquation. It further concluded that the identification and acceptance of inaccuracies how to use the regression equation to predict a model is the first step in the evolution model to a more accurate and more confidence.

The results of present study may contribute to estimation the BW of Pelibuey ewes and this information may to contribute to updating with the data for BW estimation of some parameters required by nutritional models in order to predict the performance of hair sheep breeds 24 ptedict, The authors are very grateful to Dr. Liveweight loss associated with handling and weighing of grazing sheep.
