“…The digestibility of organic matter is closely related to the digestibility of dry matter because some dry matter is organic matter consisting of crude protein, crude fat, crude fibre, and no nitrogen extract. The digestibility of organic matter shows the number of nutrients such as fats, carbohydrates, and proteins that can be digested by livestock [6,19,24] . The digestibility value of organic matter has a higher value than the digestibility value of dry matter.…”

This study aims to determine the effect of adding feed supplements of fermented shrimp waste extract in the ration on the digestibility of local chicken rations in the growth phase. The research was carried out in Jatinangor District as well as the Laboratory of Ruminant Animal Nutrition and Animal Feed Chemistry, Faculty of Animal Husbandry, Padjadjaran University, Sumedang. The method used in this study was experimental with a Complete Randomized Design (RAL). The data were analyzed by fingerprint test (ANOVA) with further tests using the Dunnet test. The object of this study consisted of 20 Sentul chickens raised from the age of 1 day to 12 weeks, divided into 5 treatments and 4 tests. The treatment consists of P0 = Basal ration without the addition of feed supplement fermented shrimp waste extract, P1 = Basal ration + 0.5% feed supplement fermented shrimp waste extract, P2 = Basal ration + 1.0% feed supplement fermented shrimp waste extract, P3 = Basal ration + 1.5% feed supplement fermented shrimp waste extract, and P4 = Basal ration + 2.0% feed supplement fermented shrimp waste extract. The changes observed are the digestibility of dry matter, the digestibility of organic matter, and the digestibility of proteins. The results showed that the addition of feed supplements for fermented shrimp waste extract had a significantly different influence on the digestibility of dry matter, the digestibility of organic matter, and the digestibility of protein. This study concludes that the addition of a feed supplement of 2% fermented shrimp waste extract in the ration can produce a high ration digestibility value for Sentul chicken in the growth phase.

“…Ethanol extract of elecampane ( Inula helenium L.) rhizome (rich source of sesquiterpenes) has shown to attenuate ascites syndrome in broiler chickens (Abolfathi et al., 2021). Root extract of Prosopis farcta (rich source of flavonoids) has shown the potential to reduce the occurrence of ascites in broiler chickens (Shirzadi et al., 2020). Supplementing broiler diets with 3 g/ kg purslane ( Portulaca oleracea L.) powder improved antioxidant status and reduced ascites incidence without affecting growth performance (Habibian et al., 2017).…”

This review covers the challenges of broiler chickens at high altitude, with the focus on growth performance and physiological response. The review also sheds light on nutritional and management interventions that help overcome the challenges raised at high altitude. Reduced concentration of atmospheric oxygen is by far the biggest challenge that remarkably affect growth performance and livability of broiler chickens reared in high altitude area. Broiler chickens have endured intensive genetic selection, which potentially predispose them to several metabolic disorders. Hypoxia is an overriding factor that may increase the incidence of metabolic disorders, mainly ascites syndrome at high altitude. Commercial broiler strains cannot fully achieve their genetic potential when raising at highland regions. Careful nutrition and management considerations are required to prevent metabolic disorders when raising broilers at high altitude. In ovo or in‐feed nutraceuticals such as l‐carnitine and guanidinoacetic acid as well as pharmaceuticals, texture of feed and the use of proper sources and levels of dietary energy and protein are important factors that need to be carefully considered for rearing broiler chickens at high altitude. Management strategies such as lighting programs have been shown to be effective to circumvent ascites prevalence. Special breeding programs may also be considered to develop strains with resistance to ascites.

This study investigates the effects of vine tea (Ampelopsis grossedentata) extract (AGE) on meat quality, gut microbiota and cecal content metabolites of Wenchang broilers. A total of 240 female Wenchang broilers aged 70 days were randomly allocated into four groups with five replicates of twelve broilers each. Broilers were fed a corn-soybean basal diet supplemented with AGE at 0 (T1), 0.2% (T2), 0.4% (T3) and 0.6% (T4) until 124 days of age. The whole feeding trial lasted 54 days. Results suggest that the content of total triglycerides and low-density lipoprotein cholesterol in serum of broilers are linearly reduced with dietary AGE supplementation (p < 0.05). The T3 and T4 groups had higher (p < 0.05) a* value in thigh and breast muscles than the T1 group. Additionally, the dietary supplementation of AGE decreased the shear force and drip loss of both thigh and breast muscles linearly (p < 0.05). Compared with the T1 group, AGE supplementation increased the levels of inosine monophosphate (IMP) significantly (p < 0.05) in both the thigh and breast muscles. Furthermore, an increase (p < 0.05) in the total unsaturated fatty acid (USFA), polyunsaturated fatty acids (PUFA) and the ratio of unsaturated fatty acids to saturated fatty acid (USFA: SFA) in both the thigh and breast muscles in the T3 group was observed. Higher abundance of Bacteroidota (p < 0.05) and lower abundance of Firmicutes (p < 0.05) were observed in the T3 group. The abundance of Faecalibacterium was significantly decreased (p < 0.05) in the T3 group compared with the T1 group. Cholesterol sulfate and p-cresol sulfate were identified as differential metabolites between the T1 and T3 groups. It suggested that 0.4% of AGE supplementation significantly downregulated the levels of p-cresol sulfate and cholesterol sulfate (p < 0.05) and the hepatic 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) activity compared with the control. Our present study demonstrates that dietary supplementation with AGE can improve the quality and flavor by increasing the IMP and PUFA content in the muscle of Wenchang broilers. Furthermore, dietary AGE supplementation with 0.4% can regulate the cholesterol metabolism of Wenchang broilers.
