Penambahan Nukleotida pada Ransum Broiler yang Dipelihara pada Suhu Lingkungan Berbeda terhadap Performa Organ Imunitas

Abstract

This study was aimed to know the effects of dietary nucleotide on the immune organs performance of broiler chickens raised under different environmental conditions. The material used was unsexed 165 birds broiler chickens 15 days old with an average body weight of 462.20±9 g (CV 3.95%), and nucleotide supplemen. The experiment was completely randomized design with factorial patern 3×3 and 5 repeats. The first factor is three different levels of dietary nucleotide T0=0g/kg, T1=0.5g/kg and T2=1g/kg of feed and the second factor is environmental conditions with S 1 =32±1°C, S 2 =23±1°C and S 3 =24 -34°C. The parameters observed were: relative weight of immune organs that is bursa fabricius, thymus and spleen. Data were analysis of variance to determine the effect of treatment at the level of 5%. It will be followed by Duncan's test if there is real treatment effect. The results showed that there was no interaction of dietary nucleotide with raised under different environmental conditions (P>0.05) and fed dietary nucleotide. Comfortable environment signifficantly (P<0.05) improved relative weight of thymus, however hot environment reduced relative weight of thymus and bursa while enhanced relative weight of spleen. In conclusion, comfortable environment supported performance of immune organs, and hot environment inhibited performance of immune organs.

Effect of the Nucleotide and Turmeric Extract Supplementation and different Cage Floors on the Blood Profile and Physiological Status of Broiler Chicken

“…The index of bursa fabricius (BFI) and lien index (LI) of broiler chickens in this study were 2.26-2.39% and 0.11±-0.15% (Table 3). BFI and LI in this study were higher than those of Hakim et al (2021), reporting that BFI and LI in broiler chickens supplemented with nucleotide were only 0.044-0.047% and 0.112-0.146%, respectively. The result of the analysis of variance showed that the supplementation of nucleotide and turmeric extract and different types of floors did not significantly affect (P>0,05) LI, but this combination significantly affected (P<0,05) the BFI of broiler chickens.…”

Stability of the Broiler Antibody Under Heat Stress Using Dry Rice

“…Data (Table 1 and Figure 4) shows relative weight of bursa fabricius T2 better than T1 and T3 that have decreased. Hakim et al [51] stated that chickens that are raised under stress conditions, such as the increase of room temperature and high density of the closed house, will reduce the relative weight of bursa fabricius. The same statement conveyed by Pamok et al [52] that in general, bursa fabricius in chicken that has heat stress may become an atrophy and reduce the number of lymphocytes.…”

Blood Profile and Carcass Production of Broiler Chickens Given Nucleotides and Turmeric Extract in Feed

“…This is because with a very fluctuating cage temperature ranging from 26 to 33 0 C, the cage temperature conditions cause chickens to experience stress. This condition is not be able to meet the adequacy of nucleotide in their body for broiler chickens (Hakim et al, 2021). In addition, it will cause damage to erythrocytes, this is because the chicken in heat stress conditions will trigger the formation of free radicals or reactive oxygen compounds.…”
