Abstract:
Crossbred cows (18), aged 2 to 4 years with average body weight of 190 kg, were randomly divided into 3 uniform groups of 6 each. All the cows were fed ad libitum green fodder and measured quantity of concentrate mixture. The cows in group T₂ were supplemented with 50 gm micro minerals/cow/day and in group T₃ were supplemented with 50 gm macro minerals/cow/day as whereas cows in group T₁ kept as control. The feeding trial lasted for 45 days. The body weight and metabolic body weight were measured at 0, 15, 30 & 45 day. The average body weight was recorded in T₂ (treatment group) at 0 day 183.33 kg. 15 days 186.91 kg. 30 days 191.93 kg. & 45 days 199.5 kg. Followed by T₃ (Treatment group) at 0 day 179.33 kg. 15 days 183.36 kg. 30 days 188.71 kg. & 45 days 199.85 kg. Lowest in T₁ (control group) at 0 day 177.16 kg. 15 days 180.86 kg. 30 days 185.35 kg. & 45 days 191.21 kg. & average metabolic body weight gain highest was recorded in T₂ (treatment group) at 0 day 49.80 kg. 15 days 50.53 kg. 30 days 51.55 kg. & 45 days 53.07 kg. Followed by T₃ (treatment group) at 0 day 48.99 kg. 15 days 49.82 kg. 30 days 50.90 kg. & 45 days 52.34 kg. & lowest in T₁ (control group) at 0 day 48.55 kg. 15 days 49.31 kg. 30 days 50.22 kg. & 45 days 51.41 kg. Body wt. & metabolic body wt. From the treatment of ANOVA design treatment significance but intrusion is non-significance. So effect of days and treatment are significantly different.
