“…Supplementation of vermi meal in the ration did not influence the FCR, water consumption, and showed a negative result in profit and return on investment because of the high cost of vermi meal. The results were consonant to the study of Zang et al (2018) that the effects of dietary supplementation with vermi meal on production performance of broiler supplemented with 0%, 1%, 3%, and 5% were the improved feed conversion ratios by 12.64-22.45%. Supplementing the diet with 5% vermi meal had no negative effect on the growth of broiler and increased antioxidant enzyme.…”

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.

Shortage of protein feed resources is the major challenge to the world farm animal industry. Insects are known as an alternative protein source for poultry. A Wwide range of insects are available for use in poultry diets.Insect larvae thrive in manure, and organic waste, and produce antimicrobial peptides to protect themselves from microbial infections, and additionally these peptides might also be functional in poultry feed. The feed containing antimicrobial peptides can improve the growth performance, nutrient digestibility, intestinal health, and immune function in poultry. Insect meal contains a higher amount of essential amino acids compared to conventional feedstuffs. Black soldier fly, mealworm, housefly, cricket/Grasshopper/Locust (Orthoptera), silkworm, and earthworm are the commonly used insect meals in broiler, and laying hen diets. This paper summarized the nutrient profiles of the insect meals, and reviewed their efficacy when included in poultry diets.Due to the differences in insect meal products, and breeds of poultry, inconsistent results were noticed among studies. The main challenge for proper utilization, and the promising prospect of insect meal in poultry diet were also addressed in the paper. In order tTo fully exploit insect meal as an alternative protein resource, and exert their functional effects, modes of action need to be understood. With the emergence of more accurate and reliable studies, insect meals will undoubtedly play more important role in poultry feed industry.

“…Some authors observed increase in body weight and decrease in feed intake in broiler chickens (Sofyan et al., 2010). There are studies revealing both parameters increased with increasing portion of EW powder in the diet (3% and 5%; Zang et al., 2018), while another authors (Bahadori et al., 2015, 2017; Rezaeipour et al., 2014) revealed the decrease in the growth performance of broiler chickens with increasing amount of EW meal. Humic substances as the main components of VH promote the growth of animals (Jaduttova et al., 2019; Ozturk et al., 2012; Yildiz et al., 2013), although in the present study, the diet containing only supplemental VH (without EW powder) had not substantial influence on weight gains of breeder quails.…”

The present study is aimed to evaluate the effects of different levels of earthworm (EW) powder and vermihumus (VH) on the growth performance, humoral immunity response, plasma constituents and reproductive performance of Japanese breeder quails. A total of 336 birds were assigned to seven treatments in a completely randomized design from day 30 to 90 of age. The dietary treatments were carried out, one without any addition of EW and VH, the second had a standard rate of VH at 0.8%, while a range of EW additions was supplied from 0%, 0.5%, 1%, 1.5%, 2% and 2.5%. The effects of treatments on body weight and mortality were not significant (p > .05). The highest feed intake was observed in birds fed the diets supplemented with 1% and 1.5% EW (p < .05). The highest titre of antibodies against influenza virus and sheep red blood cells belonged to the EW and VH treatments (p < .05). The antibody titre against Newcastle disease virus vaccine was not affected by the treatments. In general, the birds receiving EW and VH had the highest egg weight, egg production and egg mass weight (p < .05). Nonetheless, various levels of EW powder negatively affected hatchability and increased mortality and leg disorders (p < .05). The results showed that the levels of dietary 1% and 1.5% of EW powder gave the best growth and reproductive performance to birds respectively.
