dc.description.abstractThe present study on “Effect of various breed proportions on breeding values for various traits in HF crossbred cattle” was conducted with objectives: (i) to determine the proportions of exotic inheritance in the crossbred cows by SNP genotyping (ii) to study genetic parameters for production traits and AFC in crossbred cattle (iii) to estimate breeding values of sires for various traits in crossbred cattle (iv) to study the effect of various breed proportions on estimates of breeding value for various traits in crossbred cattle. For this, a total of 1,59,950 first lactation test day milk yield records of 17135 HF crossbred cows sired by 259 sires spread over a period of 23 years (1997-2019) belonging to four districts of Gujarat state viz., Panchmahal, Sabarkantha, Surat and Tapi were collected from the INAPH-MIS database maintained by NDDB, Anand. The number of records, minimum, maximum and average values were 159950, 1.00 kg, 24.93 kg and 9.12 kg for test day milk yield; 142400, 0.03 kg, 1.59 kg and 0.38 kg for test day fat yield; 133377, 0.07 kg, 2.36 kg and 0.80 kg for test day solid not fat yield; 131465, 0.02 kg, 1.03 kg and 0.30 kg for test day protein yield, respectively. The number of records, minimum, maximum and average values were 15642, 2.50%, 6.40% and 4.18% for fat percent; 14770, 7.81%, 9.95% and 8.78% for solid not fat percent; 14746, 2.43%, 4.30% and 3.34% for protein percent, respectively.en_US
