Abstract
Objective: Efficacy of AV/CSP/29 premix (Ca, P supplement with Vit. A & D3 along with synergistic herbs) (M/S Ayurvet Ltd.) was evaluated in commercial broiler chicks. Materials and methods: A total of 144 day-old chicks were randomly divided into three groups. Group T0 (n=48) control group, supplemented with basal diet without any additional source of calcium (Ca) and phosphorus (P). Group T1 (n=48) was administered with AV/CSP/29 premix at 500 gm/ton of feed and Group T2 birds (n=48) were supplemented with Brand A at 500 gm/ton of feed for 0 to 42 days. Parameters viz., growth, performance, serum biochemical and carcass quality traits were evaluated. Results: More gain in body weight was observed in the AV/CSP/29 premix supplemented group (T1) birds as compared to other groups. Similarly, FCR was improved in the AV/CSP/29 premix supplemented group (T1) birds. Blood Ca and P concentrations were comparatively improved in AV/CSP/29 premix supplemented birds. Parameters viz., carcass yield, dressing percentage, tibial mineralization, water holding capacity and extract release volume were also found to be better in AV/CSP/29 premix supplemented group (T1) birds. Conclusion: The results from the current study suggest that feeding of AV/CSP/29 premix to broiler chickens may have a beneficial effect on bone quality and in improving overall performance.
Highlights
Metabolic and structural function of Ca and P in bone and eggshell formation is essential in poultry production (Pelicia et al, 2009)
At the end of 6th week the mean body weight was non-significantly more in AV/CSP/29 premix supplemented Group T1 birds (2203.4) as compared to Brand A supplemented Group T2 birds (2137.5) but was significantly (P
Deficiency of calcium cause skeletal abnormalities, and phosphorus plays a critical role in cellular metabolism, as a part of the energy currency of the cell, in cellular regulatory mechanism, and in bone (85% of P is in bone) (Musilova et al, 2014)
Summary
Metabolic and structural function of Ca and P in bone and eggshell formation is essential in poultry production (Pelicia et al, 2009). Inadequate level of Phosphorus results in loss of skeletal integrity and loss of appetite. This results in subnormal growth in young birds and weight loss in older birds (Narcy et al, 2009; Venalainen et al, 2006). Overall deficiency or excess of Ca and P interferes with homeostasis of each other, results in depressed growth rate and bone mineralization (Shafey et al, 1990; Hurwitz et al, 1995). Deficiency of vitamin A seriously affect growth rate, feed utilization, development of bone, movements, vision, reproduction, resistance against diseases, and mortality in poultry birds (Bhuiyan et al, 2004).
