Comparative Evaluation of Growth Performance of HD-K75 Pigs under Organized Farm and Field Conditions

Abstract

Pig farming plays a vital role among the tribal population of northeastern region. Out of the different pig breeds HD-K75 variety is very popular among the farmers due to its better growth performance. It is a new variety developed by ICAR-AICRP on pigs, Khanapara, Guwahati. The present investigation was carried out to evaluate the growth performance of HD-K75 pigs under different system. Twenty-one weaned piglets of HD-K75 variety were selected from organized farm and another twenty-one from unorganized pig farm in the peri-urban area of Guwahati city were selected. The body weight and linear body measurement of the experimental animals were measured with the help of weighing balance and flexible tape, respectively at monthly interval. The average body weight of HD-K75 pigs at 2 months of age was 13±0.27 and 8.67±0.23 kg respectively, under organized and unorganized farming systems while, at 7 months of age it was 70.84±0.45 and 60.09±0.34 kg, respectively. The average daily BWG of pig under organized and unorganized farming system was 0.41±0.01 and 0.29±0.01 kg; 0.46±0.01 and 0.40±0.01 kg, respectively during 2-3, and 6-7 months of age. The linear body measurements were significantly (P<0.05) higher in pigs reared under organized farming system. The study revealed that the growth performance of HD-K75 pigs was better under organized farming system. Therefore, management practices followed in the organized farm should be implement in the field conditions.
