The present experiment aimed to establish the efficacy of a novel feed supplement (NFS) on nutrient intake, energy status, metabolic profile, milk yield, reproductive performance and its socio-economic impact on problematic postpartum buffaloes under field condition. Twenty-four post-partum buffaloes were randomly and equally assigned to CON and NFS groups for 120 days of experimental feeding period. The animals in CON group were fed on basal roughages and concentrate mixture 20% of DMI as per the farmers’ practices, whereas buffaloes in NFS group were fed according to CON with additional novel feed supplement 0.25% of BW. The voluntary feed intake and average daily gain in body weight were increased in NFS than CON group. The buffaloes fed NFS diet exhibited higher Hb, haematocrit, serum glucose and lower NEFA. Serum minerals (Ca, iP, Zn, Cu, Fe, Mn), metabolic hormones (T3, T4, GH, IGF-1) and total antioxidant capacity were enhanced in NFS group. The milk yield and conception rate were also improved significantly following strategic supplementation of NFS. Analyses of cost benefit of milk yield revelled that the benefit-cost ratio was improved in NFS fed buffaloes. Thus, it can be concluded that strategic supplementation the novel feed supplement 0.25% of BW significantly improved the nutrient intake, energy balance, metabolic profile, milk yield and reproduction performance of problematic buffaloes under field condition during early post-partum period. © 2024, Kasetsart University.

The present study aimed to evaluate the comparative nutritional value of Desi and PKM-1 varieties of Moringa oleifera foliage using in-vitro gas production (IVGP) technique in goat feeding. Five groups were established, with substrates comprising a mix of wheat straw and concentrate (60:40 ratio) without moringa foliage serving as the control (CON). The other groups were designated as P-10 and P-20 incorporating PKM-1 moringa foliage at 10% and 20%, respectively; and D-10 and D-20 incorporating Desi moringa foliage at 10% and 20%, respectively. The study revealed that PKM-1 variety exhibited significantly higher (P<0.01) organic matter (OM) and crude protein (CP) content, while total ash (TA) and neutral detergent fiber (NDF) content were significantly lower (P<0.05) compared to Desi moringa foliage. The polyphenolic content remained comparable (P>0.05) between both varieties. Additionally, PKM-1 showed significantly higher (P<0.05) levels of phosphorus (P), copper (Cu), iron (Fe), zinc (Zn) and manganese (Mn) minerals compared to Desi moringa foliage. Furthermore, total gas volume (ml/200 mg) produced after 24 hours of incubation was significantly (P<0.01) higher in P-20 group compared to CON, D-10, D-20, and P-10 groups. Substrate degradation, measured as truly degradable organic matter in the rumen (TDOMR in mg/200mg; %), was higher (P<0.01) in P-20 group, followed by D-20 and P-10 groups, while it was lowest in D-10 and CON groups. Microbial biomass production (MBP in mg/200 mg), efficiency of microbial biomass production (% TDOMR), and partitioning factor (PF in mg TDOMR/ml gas volume) were also higher (P<0.01) in P-20 group, followed by D-20, P-10, and D-10 groups, with the lowest values observed in CON group. Hence, the incorporation of PKM-1 Moringa oleifera foliage at 20% of total dry matter significantly enhanced substrate degradation, truly degradable organic matter in the rumen, and the efficiency of microbial biomass production in goat’s rumen inoculum, as compared to Desi variety. © Range Management Society of India.
