“…Carotenoids exert antioxidant effects and have known benefits to human health such as improving eye health, cardiovascular health, cognitive function and may even help prevent some types of cancer (see review by Eggersdorfer and Wyss, 2018 ). Consumers have been shown to give considerable importance to the color of egg yolks, even over other egg characteristics such as texture, flavor, and odor ( Berkhoff et al, 2020 ). In order to ensure a strong pigmentation of the egg yolks in a larvae rich diet it would be necessary to increase the provision of carotenoids in the concentrate or, perhaps, in the larvae (by supplementing their diet).…”

Feeding live Black Soldier Fly larvae (Hermetia illucens) to laying hens: effects on feed consumption, hen health, hen behavior, and egg quality

et al. 2021

The use of insects in animal feed has the potential to reduce the demand for soybean production and reduce the deforestation and loss of natural resources. In particular, the black soldier fly ( BSF , Hermetia illucens ) larvae have received attention due to their ability to convert organic waste into high-value biomass. Several studies have investigated the effects of providing BSF larvae to both broilers and laying hens. However, knowledge gaps regarding hens’ voluntary intake of live larvae and the effects of larvae consumption on egg production still remain. Therefore, the aim of the present study was to determine the effects of the consumption of 4 different amounts of live BSF larvae on laying hen feed consumption, hen health and fearfulness, and egg production and quality. To this end, 40 Bovans White laying hens were housed individually and provided with 0, 10, 20% or ad libitum daily portions of live larvae from 18 to 30 wk of age. The larvae consumption and concentrate consumption, hen weight, egg production, and egg quality were monitored. Overall, differences were found between the hens given ad libitum access to larvae compared to the other treatments. Ad libitum hens, consumed 163 ± 41 g larvae/hen/day, consumed less concentrate ( P = 0.03) and gained more weight ( P = 0.0002) than all other treatments. They also had an overall higher consumption of protein, fat and energy ( P < 0.03). There was no effect of larvae consumption on egg production, egg weight, shell thickness, shell breaking strength, or Haugh unit ( P > 0.05). There was also no effect on hen behavior toward a novel object or in an open field test. This study is the first to provide different amounts of live BSF larvae, including an ad libitum portion to laying hens. The 20% diet could promote sustainability in the egg industry and be economically advantageous if BSF larvae can be bought in bulk for less than 40% of the cost of the concentrate.

“…This sensory property also can be an indicator of some defects in milk, such as adulteration [7], spoilage [8] and the long-term storage conditions [9]. Regarding eggs, yolk [10] and shell color [11] make the valuable quality attribute for consumers' judge. In general, customers rather desire the yellow-orange egg yolk than off-white yolk [12][13].…”

“…In general, customers rather desire the yellow-orange egg yolk than off-white yolk [12][13]. In case of the eggshell, consumer priority for color differs worldwide [14]. Furthermore, white-shell eggs are desired in Japan, North and Central America, Middle East, India, Taiwan, and Philippines, whereas brown-shell eggs are opting for Latin America, Europe and China [15].…”

Rapid and objective assessment of food color is necessary in quality control. The color evaluation of animal source foods using a computer vision system (CVS) and a traditional colorimeter is examined. With the same measurement conditions, color results deviated between these two approaches. The color returned by the CVS had a close resemblance to the perceived color of the animal source foods, whereas the colorimeter returned not typical colors. The effectiveness of the CVS is confirmed by the study results. Considering these data, it could be concluded that the colorimeter is not representative method for color analysis of animal source foods, therefore, the color read by the CVS seemed to be more similar to the real ones.

“…Unfortunately, most people do not have the answer or the habit of thinking about these questions, mainly in developing countries. In Latin America, there are many researches related to the profile and behavior of the consumer of food from animal sources, and it showed that most of the people do not worry about the animals' sanitary conditions and the good hygienic practices during the production process (2,(4)(5)(6)(7)(8)(9)(10). They care most about the color, tenderness, and price of the food, and in some regions, it is explained by the low education of the population, including people who are analphabet (4).…”

Most people consume animal foods, for example meats, but few are concerned with the quality and origin of these products. Many studies point out hygiene problems of these foods after production; however, the lack of knowledge of the consumers of animal products about the importance of hygienic-sanitary control during the production process can lead them to a bad choice when buying these products and, consequently, expose themselves to the risk of acquiring many diseases, such as zoonosis. In this perspective, the objective of this work is to reflect about the consumers' role in the production of safe food of animal origin and to show that the population's health education is necessary and urgent. Only by helping the consumers to obtain knowledge about the production of animal products origin will there be a change in consumption habits, preventing the ingestion of contaminated foods that can cause damage to human health and to the environment, consequently, promoting one's health.
