Development of breeding strategy based on body coloration and phenotype in Holstein Friesian crossbreds for sustainable milk production

In this study, Holstein Friesian crossbreds were categorized based on white coloring in different body parts, hump status, and known generations derived from controlled breeding and recording. The aim of this study was to reveal the effects of morphological features on milk production; grading of Holstein Friesian crossbreds and implement a sustainable breeding strategy based on phenotypic grading. Data of peak milk production and morphological characteristics were collected on 51 Holstein Friesian crossbred cows after primary sorting from three districts (Sirajganj, Chittagong and Mymensingh) of Bangladesh. The data analyses were conducted following one-way ANOVA with descriptive statistics. The animals were graded according to the white coloring pattern (absent or present) in horn, eyelid and eyelash, muzzle, hoof, tail switch, and the presence of a hump. It was observed that the presence of white color (18.86±1.01 to 22.00±1.57 liters) in different body parts of Holstein Friesian crossbreds were significantly (p
