Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    Abstract This study was conducted to generate information regarding feeding Azolla (Azolla piñnata) for rearing broiler poultry birds. Specifically it aimed to 1) Evaluate the biological growth performance of broiler birds offered Azolla meal (AZM) with soybean meal at different nutrient densities alone and in combinations with additives. 2) Effect on blood biochemistry viz. calcium, phosphorus and cholesterol. 3) Economics of substituting Azolla meal (AZM) with soybean meal (SBM). An experiment was conducted on 110, day old commercial poultry broiler chicks which were divided into 5 main groups (1 control + 4 treatments) within 2 replicates having 11 chicks in each replicate. Four levels of Azolla (2.5 per cent, 2.5 per cent + enzymes (Hizyme & Phytase (PE)), 5.0 per cent and 5.0 per cent + enzymes (Hizyme & Phytase (PE)) served as components of T1, T2, T3, and T4 respectively, where as treatment T0 served as standard control diet. These dietary treatments were arranged in randomized block design. The substitution with dry Azolla with and without Hizyme (carbohydrase) and Phytase enzyme as an ingredient compared to a standard formulated conventional diet was done in a way that the crude protein and metabolisable energy values were similar in all treatments (T1, T2, T3, T4) and control (T0). Overall growth performance of the Azolla fed groups (T1, T2, T3, T4) was found to be comparable to the birds offered standard soybean based formulated feed (T0). Growth performance did not exhibit any significant (P<0.05) difference concluding that Azolla as unconventional feed ingredient was successful in replacing soybean meal without affecting the growth performance. Whereas feed intake per unit gain in live weight was found to be significantly (P<0.05) higher for the Azolla fed groups compared to control group, but 2.5 per cent substitution of Azolla supplemented with enzymes exhibited lower feed conversion ratio compared to treatment offered 5 per cent substituted Azolla. It was also observed that the general acceptability of cooked meat is more in broilers offered Azolla meal at 5 per cent substitution. The breast meat yield and cooking yield value was significantly higher in Azolla fed groups. There was increase in gizzard weight as well gizzard thickness in treatment groups offered 2.5 per cent Azolla substituted feed which also exhibited better feed conversion ratio. The results may be attributed to improved digestibility of nutrients because of better gizzard functioning and increased gastro duodenal reflexes facilitating the contact between nutrients and digestive enzymes. The addition of Azolla in the poultry ration did not affect the plasma mineral levels of broilers. Higher feed intake per unit gain in live weight for the Azolla fed treatments slightly increased the cost of production leading to slightly lower profits, thus Azolla meal can be used as alternative to soy bean in broiler birds. Based on the findings it can be concluded that dried Azolla meal can be safely administered as unconventional feed ingredient in commercial poultry broiler feed up to 5 per cent level without having any deleterious effect on growth, organoleptic and biochemical parameters and can be used as alternative to soy bean meal.
