    The present investigation was carried out to test the efficacy of Chlorophytum borivilianum (CB) supplementation on milk production, composition, and fatty acid profile in crossbred (KF) cows. Eighteen crossbred cows were selected randomly from the institute herd and divided as control (n = 6), treatment 1 (T1, n = 6) and treatment 2 (T2, n = 6) based on body weight (av. 410.45, 424.47, 414.45 kg) and milk yield (av. 15.17, 15.80, 15.95 kg/d), respectively. The CB was supplemented at low dose at a dose rate of 40 mg/kg BW/day (T1) and high dose at a dose rate of 80 mg/kg BW/day (T2) during hot-humid (HH) season. The parameters like milk yield, dry matter intake (DMI), and body weight were recorded and milk composition viz., milk fat, solid not fat (SNF), protein, and fatty acid profile, somatic cell count (SCC), and plasminogen were estimated. Temperature humidity index (THI) was calculated to assess the level of heat stress on animals during hot-humid (HH) season. Body weight of crossbred cows did not vary between the groups during HH season. C. borivilianum supplementation in higher dose (80 mg/kg BW/day) increased DMI (per 100 kg BW) (p < 0.01) in T2 group KF cows in comparison to T1 and control group. The supplementation of CB in high dose increased milk yield, milk fat, protein, plasminogen and decreased SCC in comparison to low dose and control. Further, ratio of saturated to unsaturated fatty acids (SFAs:UFAs) was significantly reduced (p < 0.01) due to CB supplementation at higher dose in comparison to lower dose. It was concluded that supplementation of C. borivilianum at a dose rate of 80 mg/kg BW/day was found effective to augment milk production. The reduced saturated fatty acid, milk SCC, and the increase in unsaturated fatty acid content of milk, milk plasminogen suggest that its supplementation could be used in improving the mammary health and quality of milk production in dairy animals.
