ThesisItem Open Access EFFECT OF DIETARY ORGANIC AND NANO COPPER ON GROWTH PERFORMANCE, MEAT AND EGG QUALITY TRAITS IN GIRIRAJA AND SWARNADHARA CHICKEN(KARNATAKA VETERINARY, ANIMAL AND FISHERIESSCIENCES UNIVERSITY, BIDAR, 2022) AMINULLAH; T. M. PRABHUTwo biological trials were conducted to evaluate the dietary supplementation of organic and nanoparticle forms of copper (Cu) at reduced levels in improved native strain of Giriraja and Swarnadhara chicken. The basal diets of both experiments were supplemented with inorganic CuSO4at 100% recommended level to form control (T1), while test diets T2, T3 and T4 supplemented with organic copper at 100, 75 and 50% and diets T5, T6 and T7with Cu nanoparticles at 75, 50 and 25% of recommended level, respectively. In trial I, a total of 420 one day-old Giriraja chicks were utilized for 10 weeks. The grower phase (7-10 week) and cumulative (1-10 week) body weight gain was higher (p≤0.05) in T2, while feed intake was lower (p≤0.05) and feed conversion ratio was better (p≤0.05) during chick phase (1-6 week) and cumulatively in T2 and T5 groups. The dry matter, organic matter and crude protein metabolizability and nitrogen balance was higher (p≤0.05) in T2 and T5, crude fibre, nitrogen free extract metabolizability, calcium and phosphorus balance were remained unaffected. The highest (p≤0.05) excretion and lowest retention of Cu as per cent of intake was noticed in T1, and lower excretion and higher retention was in T7, while Zn and Mn balance was not affected. The serum total protein, globulin and glucose level was (p≤0.05) affected at 3rd and 10th week, and total cholesterol was lesser (p≤0.05) in T2 and T5 only at 10th week, while triglyceride, creatinine, SGOT, SGPT, calcium and phosphorus level were remained unaffected. The breast and thigh muscle yield as per cent of live weight was higher (p≤0.05) in T5, while no difference in other carcass quality parameters including bone mineralization was observed. The Cu deposition in liver was greater (p≤0.05) in T5 and in muscle was greater (p≤0.05) in T2 and T5, while Fe, Zn and Mn were not influenced. In trial II, total 224 Swarnadhara breeder hens from 28th to 48th week of age were used for the study. The egg production performance, feed conversion ratio, egg mass, yolk index, fat content and color were not affected by different treatments. The feed intake was lower (p≤0.05), shell thickness was higher, and cumulative albumen index and Haugh unit were lower in T5, while the egg weight was higher in T6. The egg fertility was higher (p≤0.05) in T2, while its hatchability based on total eggs set improved (p≤0.05) in T2 and T3. The hatchability of fertile egg and chick quality were better (p≤0.05) in T5. It was concluded that the conventional inorganic source of CuSO4 can be reduced up to 50% and 75% using organic and nanoparticle forms of Cu, respectively without jeopardizing the growth and meat quality traits in Giriraja chicken or egg production and egg quality including hatchability in Swarnadhara breeder hens.ThesisItem Open Access IN VITRO AND IN VIVO EVALUATION OF SUPER NAPIER (PENNISETUM PURPUREUM) AND COFS-29 (MULTICUT SORGHUM) FODDERS AND THEIR SILAGES IN KENGURI SHEEP(KARNATAKA VETERINARY, ANIMAL & FISHERIES SCIENCES UNIVERSITY, NANDINAGAR,, 2022) RAVINDRA DOMBAR; B. RAMACHANDRASuper Napier fodder (SNF) and CoFS-29 (multi-cut sorghum fodder, MSF) are the most preferred and high yielding perennial cereal fodders. An attempt was made to assess the proximate and fiber fractions at different harvesting stages (first cut- at the 90th day after plantation, second (135th day) and third (180th day) cut. Proximate and fibre fractions of second and third cuts were comparable to each other and they were superior in terms of CP and EE. First cut was lower in CP% and higher in CF% when compared to the second and third. Two in vivo experiments were conducted to evaluate the DMI, digestibility and nutritive value of the SNF and MSF and their silages. In both the experiments, CFM and tur pods were supplemented to meet the nutrient requirement of adult sheep for maintenance (ICAR-2013). In Expt-I, adult Kenguri sheep were fed sorghum stover, SNF, MSF and SNF50:MSF50 (combination of two fodders at 50:50 ratio) in T-1, T-2, T-3 and T-4, respectively. The DMI of MSF (3.02%BW) and SNF50:MSF50 (2.84%BW) was significantly (P<0.01) higher than SNF (2.32%BW). Numerically higher nutrient digestibility (DCP % and TDN %) were observed in the MSF and SNF50:MSF50 fed group than SNF alone on DMB. In Expt-II, sheep were fed with sorghum stover, silage of SNF (SNS), silage of CoFS-29 (MSS) and silage of SNF50:MSF50 (SNS50:MSS50) in T- 5, T-6, T-7 and T-8, respectively. The DMI of MSS (4.04%BW) and SNS50:MSS50 (4.11%BW) were significantly (P<0.01) higher than SNS (3.20%BW). However, no significant difference was observed between SNS and SNS50:MSS50 in terms of DMI, digestibility of nutrients, DCP and TDN content. Numerically higher nutrient digestibility (%), DCP (%) and TDN (%) were observed in the MSS and SNS50:MSS50 than the SNS fed group. In vitro study revealed that ME, TDOM, PF, MBP and EMBP at t1/2 were higher for MSS and SNS50:MSS50 among the green fodders and silages. It can be concluded that SNF50:MSF50, SNS50:MSS50, MSF and MSS are more palatable, have beneficial role in feeding of small ruminants compared to SNF and SNS alone. SNF, MSF and SNF50:MSF50 can be stored as silage like other variteis of Napier and Multi-cut sorghum.ThesisItem Open Access Ruminant Feedevaluationforfermentation Characteristics And Microbial Biomasssynthesis(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2007) T.
