Conversion of energy and protein rich food waste as an alternative feed ingredient in broiler feed formulation.

A series of experiments were performed to find out the impact of food waste on growth attributes and performance of broilers in a tropical climate. Two hundred and fifty-one-day-old broiler chicks were randomly separated into 5 groups, where each group comprised 50 animals. The broilers were fed with five different dietary treatments. Treatment 1 (T1), the diet consisted of food waste ingredients such as sprat heads, fish offal (protein), scraped coconut, and swill cooked rice as energy supplements; dietary treatment II (T2) diet was formulated with protein rich food waste; treatment III (T3) diet formulated with energy-rich food waste; treatment IV (T4) without any food waste materials, but a diet formulated with commercially available feed ingredients; and treatment V (T5), a 100% commercially-available broiler diet. Total feed intake per week and total weight gain were significantly (p < 0.05) higher in the commercial diet (T5) contrary to the formulated diets. The highest feed conversion ratio (FCR) was recorded in T3. The average dressing percentage was not significantly different (p > 0.05) in T1, T3, and T5. Average DM % in litter and DM % in feces were higher in T5, but average nitrogen % in droppings were lower in T4 and T5 compared to other diets. The study shows the potential application of food waste as an alternative feed in the broiler industry and its abundance and easy collection makes it a promising feeding regime in urban and suburban areas.

Nutritional and Health Benefits of Jackfruit (Artocarpus heterophyllus Lam.): A Review.

Artocarpus heterophyllus Lam., which is commonly known as jackfruit is a tropical climacteric fruit, belonging to Moraceae family, is native to Western Ghats of India and common in Asia, Africa, and some regions in South America. It is known to be the largest edible fruit in the world. Jackfruit is rich in nutrients including carbohydrates, proteins, vitamins, minerals, and phytochemicals. Both the seeds and the flesh of jackfruit are consumed as curries and boiled forms, while the flesh in fully ripen stage can be eaten directly as a fruit. Several countries have developed different food products such as jam, jellies, marmalades, and ice creams using pureed jackfruit. The several parts of jack tree including fruits, leaves, and barks have been extensively used in traditional medicine due to its anticarcinogenic, antimicrobial, antifungal, anti-inflammatory, wound healing, and hypoglycemic effects. Despite all these benefits, unfortunately, the fruit is underutilized in commercial scale processing in regions where it is grown. The aim of this review is to disseminate the knowledge on nutritional and health benefits of jackfruit, in order to promote utilization of jackfruit for commercial scale food production.
