Tingginya suhu lingkungan didaerah tropis menyebabkan ternak unggas mengalami stress panas. Stresss panas pada unggas khususnya puyuh dapat memicu timbulnya berbagai penyakit, mempengaruhi pertumbuhan dan produksi telur. Cara yang bisa dilakukan untuk mengurangi stress panas pada puyuh ialah dengan memberikan feed additive berupa vitamin C, mengingat vitamin C mengandung antioksidan yang dap  at digunakan untuk meredam radikal bebas yang menyebabkan stress pada puyuh. Tujuan ditulisnya artikel ini adalah untuk mengetahui seberapa besar manfaat vitamin C sebagai feed additive untuk mengurangi stress pada ternak puyuh. Materi dan metode yang digunakan dalam penulisan artikel ini adalah kajian pustaka yang selanjutnya dianalisis menggunakan pendekatan diskriptif kualitatif.  Hasil dan pembahasan berisi tentang Stress pada unggas yang ditandai dengan peningkatan tekanan darah, otot, sensitivitas saraf, gula darah dan respirasi. Ketika stress terjadi secara berkelanjutan maka tubuh akan mengaktifkan hypothalamic-pituitary-adrenal cortical system. Penggunaan antioksidan yang murah bisa dengan memanfaatkan vitamin C, tak hanya itu vitamin C juga memiliki kelebihan lain seperti vitamin C, yakni mampu mengembalikan radikal tokoferol menjadi alfa tokoferol yang stabil.

Abstract The present study aimed to evaluate the effects of dietary copper nanoparticles (Cu-NPs) and vitamin C (VC) supplementations on rainbow trout (Oncorhynchus mykiss) juveniles. Six trial diets were supplemented with Cu-NPs and VC including 0/0 (T1, control diet), 0/250 (T2), 0/500 (T3), 2/250 (T4), 2/500 (T5), and 2/0 (T6) mg Cu-NPs/VC per kg diet. After the feeding trial for 60 days, the fish were challenged with Yersinia ruckeri and the survival rate was calculated for 15 days. Based on the data analysis, weight gain (WG), feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER), lysozyme, alternative complement activity (ACH50), catalase (CAT), glutathione peroxidase (GPX), hematocrit (Hct) and mean corpuscular volume (MCV) were significantly (p < 0.05) affected by the Cu-NPs factor. Meanwhile, VC was a significant factor for hemoglobin (Hb) and superoxide dismutase (SOD) (p < 0.05). The results showed that the Cu-NPs and/or VC-supplemented diets improved WG, FCR, SGR, PER, lysozyme, ACH50, SOD, CAT, GPX, Hb, Hct, and MCV when compared with the control group (p < 0.05). The expressions of TNF-α, IL-1ß, IL-10, SOD, CAT, and GPX genes were significantly (p < 0.05) decreased in the fish fed on T3, T4, and T5 diets versus the control. In addition, the dietary Cu-NPs and VC supplementations significantly enhanced resistance against pathogens and led to the control of infection in rainbow trout. In conclusion, Cu-NPs and VC administered as feed additive at 2/250–500 mg/kg elevated the growth performance, antioxidant capacity, and health of rainbow trout.

The aim of the study was to determine the effect of vitamin C on indicators of gilts and sows reproductive value. The study was conducted using 64 gilts of the Pulawska breed. The experimental gilts received a supplement of vitamin C in an amount of 2.4 g daily throughout the whole experiment. Sixteen gilts from both control and experimental groups were mated in their third estrus. In order to determine the number of corpora lutea and the state of development of the reproductive organs, other gilts from the control and experimental groups were slaughtered after third estrus between the 5th and 10th day of the following estrous cycle. The results showed that gilts from the experimental group were characterized by higher potential fertility, as well as reared more piglets per litter. In the body weight and backfat thickness of sows during the first reproduction cycle in the control and experimental groups were not statistically significantly different. The piglets in the experimental group had higher body weight in the 1st and 21st day of rearing. Larger contents of protein, immunoglobulins, and vitamin C were recorded in the colostrum and milk from experimental sows.
