Performance of dairy cattle under two different feeding systems, as practiced in Kiambu and Nyandarua district of Central Kenya

Abstract

A study was carried out in Central Kenya to compare the performance of dairy cattle under two different feeding systems, stall feeding in Kiambu and grazing in Nyandarua. A total of 23 dairy farmers were randomly selected, 11 from the Kiambu district with a total of 61 cows and 12 from Nyandarua district with a total of 102 cows. Data on milk production and reproduction was collected over a period of two years. Stall-fed cattle showed a significantly higher milk yield (P <0.05) than the grazed animals over a 10 month lactation period (3,150 vs 2,299 kg/lactation). In both feeding systems Ayshires performed better than the other breeds. The cross-bred animals compared well with pure-breds in the grazing system. Lactation yield increased with parity for the stall-fed animals while for grazed animals, milk yield declined from the 5th parity onwards. The calving intervals were long for both feeding systems (437 vs 513 days, stall-fed vs grazed, respectively). Services per conception were significantly lower (P <0.05) for stall-fed (1.85 vs 2.36) compared to grazed animals. Calving season did not have any significant effect on milk yield in both feeding systems but animals calving during the wet season, on average, had a  More>>
