    (Mdpi, 2022) Asghar, Muhammad Umair; Dogan, Sibel Canogullari; Wilk, Martyna; Korczynski, Mariusz
    Simple Summary Over the last decade, there has been a surge of interest in the use of natural herbs as antibiotic alternatives or natural feed additives in diets to boost animal productivity and optimize the potential production. One of the natural feed additives is black cumin powder (BCP), which is characterized by high antioxidant activity and high phenolic contents. The aim of this study was to evaluate the influence of varying levels of BCP added to the Japanese quail diet on the growth, slaughter carcass, sensory features, and some meat preservation properties. It is worth noting that BCP lowered the overall quantity of bacteria and increased the quality of meat preservation. According to our findings, the supplementation of BCP had a positive influence on the quail growth, lipid profile, antioxidant, immunity, meat storage quality, pH, and decrease in pathogenic bacteria content. The current study was conducted to determine the effect of adding black cumin (Nigella sativa) powder (BCP) to the Japanese quail diet on the carcass characteristics and meat quality. In this research, 240 Japanese quail chicks (mean initial body weight 9.15 +/- 0.12) were divided into four groups of four replications each. Treatments consisted of the addition of BCP at levels 1, 2, and 4% to the mixed feed and control group without the BCP additive. Compared to the other groups, the group with the 2% BCP diet had a higher live weight (LW), body weight gain (BWG), and a better feed conversion ratio (FCR, p < 0.05). BCP administration had no impact on the carcass characteristics, however, BCP had a significant effect on the thigh and breast meat. The animal study protocol was approved by the Nigde Governorship, Provincial Directorate of Agriculture and Forestry, Turkey (protocol code: E-15018773-050.01.04-75932 and date of approval: 26 April 2021) for studies involving animals. Lower thiobarbituric acid (TBA), pH, peroxide, and total psychrophilic bacteria levels were found in the BCP added groups compared to the control group (p < 0.05). When compared with the control, the sensory properties such as color, juiciness, softness, and flavor were significantly higher in the BCP treated groups, especially when fed the 2% BCP diet. It can be concluded that BCP as an additive to quail feeds had a significant effect on the performance of quails as well as on the shelf life of the meat. In order to avoid health and environmental concerns, it was concluded that BCP can be used as a natural additive to replace synthetic antimicrobials and antioxidants at the level of 1-2% in quail compound feeds.

    Insect Meal as an Alternative to Protein Concentrates in Poultry Nutrition with Future Perspectives (An Updated Review)
    (Mdpi, 2023) Sajid, Qurat Ul Ain; Asghar, Muhammad Umair; Tariq, Haneef; Wilk, Martyna; Platek, Arkadiusz
    In recent years, interest has grown among poultry nutritionists in using alternative protein sources, such as insect meal, to meet the protein requirements of poultry due to sustainability concerns surrounding traditional protein sources such as soybean and fish meal. Insect meal can be produced from different insects, including black soldier fly, mealworms, and house crickets, and its nutrient composition varies depending on the insect species, the substrate they are reared on, and the production method. This review article provides an updated overview of insect meal as a new form of protein concentrate in poultry diets, including its nutritional value, advantages, challenges, and future prospects. Insect meal has been shown to be a rich source of protein, amino acids (lysine, methionine), and minerals (calcium, phosphorus, zinc), with a high digestibility rate, making it a valuable feed ingredient for poultry production. Additionally, using insect meal in poultry feed could reduce the cost of production and the environmental impact on the industry. Furthermore, the use of insect meal has the potential to improve the growth performance and meat quality of poultry species. However, several challenges related to large-scale insect production, legal regulatory frameworks, and consumer acceptance need to be addressed. Future research and development could help overcome these challenges and increase the adoption of insects as a potential source of protein in poultry feed. This review provides an updated and comprehensive overview of insects as a potential source of protein for poultry nutrition and highlights the possible perspectives of insect meal to contribute to a more sustainable and efficient poultry production system. While challenges remain, the utilization of insect meal in poultry feed has the capability to enhance the sustainability and efficiency in the poultry industry. Hence, insect meal emerges as a highly encouraging protein alternative, offering sustainable prospects for its utilization within the poultry sector. However, advancements in insect production technology and efficiency have the potential to raise the production scale while lowering prices, making insect meals more affordable compared to conventional protein sources. Based on the comprehensive analysis, it is recommended to further explore the practical implementation of insect meal as a reliable and efficient means of supplying protein in poultry nutrition.

    The Effect of Quinoa Seed (Chenopodium quinoa Willd.) Extract on the Performance, Carcass Characteristics, and Meat Quality in Japanese Quails (Coturnix coturnix japonica)
    (Mdpi, 2022) Naimati, Shaistah; Dogan, Sibel Canogullari; Asghar, Muhammad Umair; Wilk, Martyna; Korczynski, Mariusz
    Simple Summary There has been a rise of interest in using natural herbs as antibiotic alternatives or natural feed additives in diets to enhance animal productivity and maximize potential production during the last decades. Quinoa seed extract (QSE), which has a high antioxidant activity and phenolic content, is one of the natural feed additives. Quinoa (Chenopodium quinoa Willd.), a gluten-free pseudocereal, has grown in popularity over the years. Quinoa is a good source of protein (vital amino acids like lysine and methionine), carbohydrates, fiber, tocopherols (vitamin E), unsaturated fatty acids, and polyphenols. This research aimed to evaluate the effects of different amounts of QSE in the Japanese quail diet on growth, slaughter carcass, sensory characteristics, and certain meat preservation capabilities. The addition of QSE had a good effect on quail weight gain and growth of animals, lipid profile, antioxidant, immunity, meat storage quality, pH, and pathogenic bacteria content, according to our findings. It is worth mentioning that QSE reduced overall bacteria levels while improving meat preservation quality. According to the presented research, the best results of quail performance were obtained with 0.2 g/kg and 0.4 g QSE/kg of the quail's fodder. While the addition of 0.4 g QSE/kg of the quail's fodder had a significant effect on meat shelf life and could be used in poultry mixed feed to prevent or delay lipid oxidation of meat. This research was conducted to determine the effect of quinoa seed (Chenopodium quinoa Willd.) extract on the performance, carcass parameters, and meat quality in Japanese quails. In this study, 400 quail chicks were divided into a control group (without quinoa seed extract addition) and 3 experiment groups (4 replicates containing 25 quails in each). Commercial feed and the addition of different concentrations of quinoa seed extract (QSE) 0.1 g/kg, 0.2 g/kg, and 0.4 g/kg were used in the study. During the second week of the experiment, the highest feed intake was obtained from the supplemented groups (p < 0.01). After 5 weeks of experimentation, the highest feed consumption was noticed in the group with 0.4 g of QSE additive. The QSE additive affected the live weight gain values of all experimental groups during 1 week of the experiment. The highest values of hot carcass weight were noticed in groups with 0.2 and 0.4 g of QSE additive (p < 0.01). While the highest value of cold carcass weight was noticed in a group with 0.2 g of QSE additive (p < 0.05). Thigh, breast, back and neck ratio, and internal organs (except gizzard) were not affected by the supplementation of QSE. As a result of storage of breast meat at 4 degrees C for 0, 1 days, 3 days, 5 days, and 7 days, it was determined that the number of pH, thiobarbituric acid, peroxide, and total psychrophilic bacteria were lower in the groups with QSE as compared to the control group (p < 0.05). In conclusion, the best results of quail performance were obtained with 0.2 g/kg and 0.4 g QSE/kg of the quail's fodder. While the addition of 0.4 g QSE/kg of the quail's fodder had a significant effect on meat shelf life and could be used in poultry mixed feed to prevent or delay lipid oxidation of meat.
