- Abstract
The variation in feeding frequency and fodder particle size affects the production of lactating animals by altering the rumen ecology. The present study was aimed to investigate the effect of different fodder particle sizes and feeding frequencies on the production performance and milk composition in lactating cows. Sahiwal breed cows (n=15) having uniform age and milk yield were selected and randomly divided in 5 equal groups. Two fodder sizes, C1 (20 mm) and C2 (40 mm) were offered to animals with two feeding frequencies, F1 (twice daily) and F2 (thrice daily). Five different treatments were allotted accordingly; T1 = C1F1, T2 = C1F2, T3 = C2F1, T4 = C2F2 and T5 (control) given whole fodder once daily. The study lasted for 13 weeks with the first week to acclimatize the experimental animals with feeding routine. Results showed that in group T4, the dry matter intake (11.04±0.05kg) and milk yield (6.30±0.06 kg) were significantly higher (P<0.05) as compared to other groups while milk fat (4.67±0.05%) and total solids (12.14±0.094%) were significantly higher (P<0.05) in T3 when compared with other groups. Similarly, T5 showed significantly higher values of solid not fat (7.62±0.046) than other groups. On the other hand, milk protein percentage showed a non-significant (P>0.05) difference among all treatment groups. It was concluded that fodder particle size and the feeding frequency showed a significant effect on production performance and milk composition parameters in lactating Sahiwal cows.
