Background: Many cross pollinated flowering plants rely on pollinators for reproduction and survival. The pigeon pea (arhar), Cajanus cajan L., is the India&rsquo;s most important pulse crop. It attracts pollinators because to its cross pollination nature, possible nectar and pollen source, attractive colour and scent of the seeds and timing of blossoming. As a result, a complete research of pigeon pea insect pollinator fauna shall be used to conserve those fauna for increasing pigeon pea pollination effectiveness. 
 
Methods: Diversity of different pollinating agents associated with the crop pigeon pea by observing their abundance, diversity, percentage contribution, dominance status and diversity following the statistical diversity indexes were recorded during Kharif, 2021-22 in the state of Odisha where the insect pollinators&rsquo; fauna was recorded through fixed plot survey. 
 
Result: Megachille lanata (Fabricius) was found to be the most dominant pollinator throughout the flowering period among seven different pollinators of order Hymenoptera. M. lanata and Megachille disjuncta (Fabricius) shown higher foraging activity i.e. 6.02 bees/5 min/m2 and 4.25 bees/5 min/m2 respectively. Subdominant class represented maximum species among different dominant status classes exhibited. Very less diversity was observed throughout the season but still more diversity has been observed at mid flowering stags during 10:00-11:00 AM..

<div>Background: The effect of a phyto-supplement (PS) composed of Aerva lanata, Piper betle, Cynodon dactylon and Piper nigrum on carcass characteristics was evaluated in commercial broiler chicken. 
 
Methods: A total of 192 day-old commercial broiler chicks were allocated to the four experimental groups and each group was separated into 6 replicates, with 8 birds per replicate. The dietary treatment groups were the positive control (basal diet + antibiotic, chlortetracycline @355g/ metric ton of feed), negative control (0% PS: basal diet only), 1% PS (basal diet +1% PS) and 2% PS (basal diet +2%PS). The trial lasted for 42 days (0 to 42&nbsp;D of age).&nbsp;The carcass characteristics were recorded for two birds from each replicate at the end of the trial.&nbsp; 
 
Result: The broilers fed chlortetracycline and 1% PS recorded the highest (P=0.0205) and those fed only basal diet (negative control) recorded the lowest dressing percentage. Broilers fed diet supplemented with 1 and 2% PS exhibited higher (P&lt;0.0001) weight and relative weight of lung than other treatments. Broilers fed diet supplemented with 1 and 2% PS exhibited lower weight&nbsp;(P=0.0032) and relative weight (P=0.0002) of liver when compared with the antibiotic treatment. Feeding 1% PS increased the relative weight of heart quadratically (P=0.044) while 2% PS reduced the weight of heart. Broilers on negative control diet recorded the highest weight (P=0.0002) and relative weight (P&lt;0.0001) of kidney.</div>
