Abstract

Feed additives are one of the most essential parts of broiler production. Feed additives such as citric acid and microbial phytase are usually used separately despite the theory that they can work together. In this study, 320 broiler birds were reared and then fed four different treatments. 10 birds were reared per pen and there were 8 replications per treatment. The birds were reared using normal broiler management and health management protocols. The growth parameters and mortalities were recorded after each growth period. Production cost and the market price during the duration of the experiment were used to assess profitability. Out of all the treatments, the combination of the citric acid and microbial phytase gave the highest body weight, weight gain, second-lowest feed intake, best feed conversion ratio, and the highest profitability. Results indicated that there is a synergistic interaction with the combination of 3% citric acid and 500 U/kg microbial phytases. The concurrent supplementation produced a significant increase in the growth parameters and profitability.

Abstract

Poultry production contributes significantly to the agricultural economy. Nutrition is one important factor in having competent poultry production. Currently, there is a lot of research about natural alternatives or feed additives that are low in cost and can help increase the overall performance and improve poultry health conditions without any adverse effects. Macroalgae such as green seaweeds can meet these parameters. It is easily available and is considered a rich source of proteins, polysaccharides, carbohydrates, vitamins, minerals, pigments, and antioxidants. Most often, seaweeds are used as feed additives for broiler chickens as they can induce a beneficial impact on production parameters (body weight (BW), average daily gain (ADG), feed consumption (FC), and feed conversion ratio (FCR) and meat quality. However, there are several challenges in using green seaweed as a protein alternative for broiler chickens such as its toxic and antinutritional components, as well as varying available supply due to seasonal effects, diseases, location, and environmental pollution. Furthermore, the main objective of this review is to evaluate the different research conducted on green seaweed as a potential protein source in broilers.
