Abstract
This study was aimed to identify the phenotypic features of local Pabna calves including their growth trait attributes at BLRI Regional Station, Baghabari. Data on different phenotypic measurements and growth traits were collected from 12 half sib Pabna baby calves. Each calf was allowed to drink 10% of milk for individual’s body weight from respective dam. Data analyses were conducted following independent sample t-test and one-way ANOVA using SAS 9.1.3 (SAS Institute Inc., Cary, NC, USA). Although significant differences observed in body weight (p<0.001), body length (p<0.05), heart girth (p<0.05) and mouth circumference (p<0.05) based on two types of birth weight groups in calves (<20 kg and ≥20 kg) but there were limited effects observed in the baby calves at three months except head length (p<0.05) considering dam’s body weights. Observed growth rate has no variations (p>0.05) in baby calves. This study revealed that half sib calves originated from the same sire had similar morphological features and growth in the early stage while dams’ body weight had limited effects on those aspects.

Highlights
Pabna cattle are one of the most promising local varieties for productivity among the available cattle varieties which was originated from the area of Pabna and Sirajganj districts of Bangladesh having disease resistant capability and environmental adaptability (Ghosh, 1981; Majid et al, 1992; Bhuiyan et al, 2007)
Source of data Data on different phenotypic measurements and growth traits were collected from 12 half sib Pabna baby calves having same sire using measuring tape and digital weighing balance within three months of calving, respectively, at BLRI Regional Station, Baghabari during January-June in 2018
The morphological features of Pabna calves at birth had significant differences in body weight (p
Summary
Pabna cattle are one of the most promising local varieties for productivity among the available cattle varieties which was originated from the area of Pabna and Sirajganj districts of Bangladesh having disease resistant capability and environmental adaptability (Ghosh, 1981; Majid et al, 1992; Bhuiyan et al, 2007). Phenotypic characterization contributes to the improvement of animal genetic resources in the context of country-level implementation (FAO, 2012). The study of Talukder et al (2017) revealed that morphological features were not varied between local Pabna cows populations except body length, height at wither, pelvic length, tail dock circumference and mouth circumference. Several studies had been carried out for local Pabna cattle in Bangladesh (Husain et al, 1984; Husain and Mostafa, 1985; Khan et al, 1999), but the in-depth studies on morphological and growth traits of half sib baby calves are not conducted yet. This study was aimed to reveal the phenotypic features of local Pabna calves including their growth trait features.
