“…Separate data and pedigree files for each trait were prepared in excel sheets. The year was divided into five seasons as defined by Mirza et al (2015). The other factors were herd (1-5), parity (1-4).…”

Current study was conducted to find out heritability estimates of some body measurements of Nili Ravi buffaloes maintained at 5 Livestock Experiment Stations in Punjab Pakistan. Recording of body measurements was continued for 3 years since 2010 to 2012. Heritabilities of traits were estimated using BLUP (Best Linear Unbiased Prediction) evaluation techniques. Influencing factors such as age of the buffalo at scoring, stage of lactation, parity, herd and season were included in the model. Individual Animal Model was fitted under Restricted Maximum Likelihood (REML) Procedure. Data were analysed using the mixed model procedure of the Statistical Analysis Systems. Fixed effects observed to be significant in the initial analysis were included in the model for estimation of variance components from which genetic parameters were estimated. The ASREML set of computer programs was used to estimate heritabilities.

“…There is also high diversity of heritability of cattle temperament (Miglior et al, 2017). Cattle temperament heritability parameters have been estimated 0.18-0.22 and 0.25 for Holstein -Friesian and Jersey, respectively (Mirza et al, 2015).In addition, heritability index of cattle temperament has been reported 0-0.61 and 0.11-0.31 for beef cattle (Vogt et al, 2017).Almost high heritability index (0.36, 0.44 and 0.5) have been recorded for nutritional behaviors (duration, and speed of feeding respectively; figure 5) of hybrid cattle of Bos taurus and Bos indicus. There is low or medium heritability for social and reproductive behaviors.…”

Behavioral traits are the main controllable factors for domesticating cattle. The traits profoundly influence on the longevity of cattle and play a remarkable role in animal welfare assessment and animal ethics limitations determination. In the present study, the genetics of cattle behavior is discussed. Current breeding status of cattle behavioral traits is also reviewed, regarding the high individual variation of behavioral traits and almost high correlations between the traits and performance. Moreover, recent findings of characterizing quantitative trait loci (QTL) for behavioral traits of cattle is considered, as well as the most important problems in the breeding of cattle behavioral traits such as a large variety of methods which are used to evaluate the traits.
