EFFECT OF Α-Tocopherol AND ASCORBIC ACIDS ON PERFORMANCE AND BLOOD IMMUNITY PROFILE OF MALE NATIVE MUSCOVY DUCK

Abstract

The purpose of the research was to assess the effect of α-tocopherol and ascobic acids on the performance and immunity blood profile of male native Muscovy duck. The materials used were 84 male Muscovy ducks at 9 weeks old. The research used completely randomized design with 7 treatments. The treatments were E0C0 : basal diet without α-tocopherol and ascobic acids, E400: basal diet+ α-tocopherol 400IU, E600: basal diet+α-tocopherol 600IU, C400: basal diet+ascorbic acid 400mg/kg, C600: basal diet+ascorbic acid 600mg/kg, E200C200: basal diet+α-tocopherol 200IU+ ascorbic acid 200mg/kg, and E300C300: basal diet+α-tocopherol 300IU+ ascorbic acid 300mg/kg. Each treatment was repeated 4 times and each replication consisted of 3 ducks. The observed variables were body weight, feed consumption, feed conversion ratio, packed cell volume (PCV), total of plasma protein (TPP), leucocyte count, basophil, heterophil, eosinophil, monocyte, lymphocytes count and heterophil/lymphocyte (H/L) ratio of Muscovy duck. The result indicated that E0C0, E400, E600, C400, C600, E200C200 and E300C300 had no significant difference in body weight, feed intake and feed conversion. There were significant effects on PCV, leucocyte count, percentage of heterophil and lymphocytes, but had no significant effect on eosinophil, monocyte and the H/L ratio. The C400 resulted a higher PCV count, percentage of heterophil, and H/L ratio. The C 600 produced the highest leucocyte count. In conclusion, the supplementation of ascorbic acid at 400 - 600 mg/kg feed ascorbic acid could improve theimmune profile, but could not improve the performance of Muscovy duck.

Hematological Features of Cihateup’s Duck Blood that are Given Natural Isotonic in Dry Systems

“…The hematologic picture of Cihateup duck blood in this study is in the normal range for poultry, especially ducks. The level of duck blood leukocytes from this study was higher than that of Tugiyanti [10] and Zapletal [11], which is in the range of (9.65 to 17.38) 10 3 (mm 3 ) -1 [10] and (23.4 to 24.8) 10 3 (mm 3 ) -1 [11]. The results of Pramana and Suprijatna [12], are around (22.28 to 36.33) 10 3 (mm 3 ) -1 .…”

Physiological and Immunological Performance of Domyati Ducklings Fed Different Levels of Coconut Oil

“…These results are in good agreement with El-Kholy et al (2014) indicating that the inclusion levels of CO in the diet are very effective on humoral immunity and immune cells of poultry. These results suggest that CO inclusion may enhance immune system activity through several fatty acids, which are potent as immune stimulants (Tugiyanti1 et al, 2016); and phenolic compounds in CO, such as caffeic, p-coumaric and ferulic acids and catechin, which improve antioxidant capacity (Kapila and Dissanayake, 2008). These changes could be attributed either to a direct stimulating effect of CO on the lymphoid organs or to the production of specific or non-specific antibodies against different antigens.…”

“…Besides in vitro test showed that several fatty acids in CO are potential as antibacterial (Bergsson et al, 2001), antivirus (Bartolotta et al, 2001, and immune-stimulant (Witcher et al, 1996), which are important to fight infection. The immune system required antioxidants product that maintained the balance of immune cells (haematopoesis), protects cell membranes from ROS, to fight microorganisms cause disease (Tugiyanti1 et al, 2016). Mohammadzade et al (2013) showed that with application of medium chain fatty acids as a prebiotic there is no need to antibiotic administration.…”

The effects of native chicken strains and feed addives on immunity, kidney functions, and blood protein

“…The mean leukocyte number in broiler chickens and thermal environmental data of the pen under the natural light-dark cycle was 13.78 ± 1.8 (x 10 3 /ml) (Makeri et al, 2017). According to Tugiyanti et al, (2016) the total and types of leukocytes may serve as the parameter for poultry diagnostic and infection status. A high number of leukocytes reflects an optimal body immune.…”
