    Effect of feeding Mint (Mentha spicata) and Indian Bay Leaf (Cinnamomum tamala) on Performance, Carcass traits and Nutrient Utilization in Broiler Chicks
    (The Association of Mastitis, 2024-06) Gurjar, Mukesh Kumar; Nehra, Rajesh; Dhuria, Rajesh Kumar; Kumar, Mangesh; Ram, Luna
    A six-week study was carried out to investigate the effect of dietary supplementation of mint powder and Indian bay leaf powder alone and in combination on performance, carcass traits and nutrient utilization in broiler chicks. Three hundred chicks were equally and randomly divided into ten dietary treatment groups having two replicates in each. The T1 i.e. control group was fed on basal diet while T 2 , T3 and T4 groups have 0.50%, 1.0% and 1.50% of mint powder and T 5, T6 and T 7 groups have Indian bay leaf powder @ 0.50%, 1.0% and 1.50% levels, respectively. T8 , T9 and T10 treatment groups were supplemented with 0.25%, 0.50% & 0.75% of both the herbs. Results indicated the inclusion of herbal feed additive alone and in combination increased feed intake (P<0.05) and body weight, weight gain, feed conversion ratio (FCR) and performance index (P<0.01) as compared to control. Body weight, weight gain, feed conversion ratio and performance index were highest in T7 treatment group i.e. group supplemented with 1.5% level of Indian bay leaf powder. Similarly, the metabolizability of dry matter (P<0.05) and crude protein (P<0.01) also increase significantly on supplementation of these herbs alone and in combination. However, no effect was recorded on the protein efficiency ratio; dressed weight percent, eviscerated yield percent and percent yield of giblet, heart, liver and gizzard. Thus, it can be concluded that the supplementation of herbs in broiler feed has increased performance. Further, Indian bay leaf powder at 1.5% level could be suggested for the best broiler performance.

    Effect of Supplementation of Ginger Root Powder and Black Cumin Seed Powder on Performance of White Leghorn Layers
    (Association of Mastitis, 2019-10) Kumar, Mangesh; Arya, R.S.; Dhuria, R.K.; Nehra, Rajesh; Jain, Dinesh
    This study was conducted to investigate the effects of different levels of ginger root powder and black cumin seed powder alone or in combination on performance and egg production in laying hens. A total of 270 Leghorn laying hens of 28 weeks old were randomly distributed among nine groups with 30 layers in each treatment with three replications following the factorial design (32). Experimental diets consisted of 0.00%, 0.50% and 1.00% levels of ginger root powder and black cumin seed powder alone or in combination. The experimental period lasted for a total of 84 days and laying hens’ performance was measured. Non-significant effect was observed on feed intake due to supplementation of black cumin seed powder whereas, significant (P<0.05) effect was observed due to ginger root powder supplementation. T5 treatment group which was supplemented with 0.00% ginger root powder and 1.00% black cumin seed powder had significantly (P<0.01) highest egg weight, egg production and egg mass along with best feed conversion ratio. It can be concluded that supplementation of 1.00% level of black cumin seed powder was recommended for best layer performance.
