Effects of feeding maize stover and cottonseed cake on onset of puberty in Bunaji (Bos indicus) heifers

A study was conducted to determine the influence of maize stover and cottonseed cake supplementation on age and live weight at onset of puberty in Bunaji heifers. A total of 49 pre-pubertal Bunaji heifers approximately 12 months of age were allotted randomly to one of two treatments of feed suppleme...

Description
Summary:A study was conducted to determine the influence of maize stover and cottonseed cake supplementation on age and live weight at onset of puberty in Bunaji heifers. A total of 49 pre-pubertal Bunaji heifers approximately 12 months of age were allotted randomly to one of two treatments of feed supplementation: (i) supplementation with maize stover and (ii) supplementation with cottonseed cake. The heifers were monitored for a period of 18 months for first observable oestrus or onset of puberty. The maize stover group were given maize stover (crop residue) supplementation ad libitum during the dry season; in the cottonseed cake group each heifer received 500 g of cottonseed cake per day during the dry season. The heifers supplemented with cottonseed cake attained puberty at an earlier age (23.9+/-1.2 months) than the heifers supplemented with maize stover (28.2+/-1.3 months; p
