“…Based on the Codex Alimentarius (FAO/WHO 2007), the sago grub is not a source of iron and calcium. This is as expected since invertebrates without a mineralized skeleton can contain very little calcium (de Castro et al 2018). On the other hand, the sago grub can be labelled as a source of zinc and magnesium.…”

“…Palmitic (42%), oleic (45%), and linoleic (3%) acids are the major fatty acids in the sago grub oil which were similarly observed by Ekpo and Onigbinde (2005) on Rhynchophorus phoenicis, with the larva oil containing palmitic (32%), oleic (40%) and linoleic (13%) acids. Generally, insects have more unsaturated fatty acids (UFA) compared to saturated fatty acids (SFA) (de Castro et al 2018). The sago grub has a higher SFA (48%) and MUFA (48%), but a lower PUFA (5%) content compared to the larvae of Rhynchophorus phoenicis and Rhynchophorus palmarum from Nigeria with SFA ranging from 29 to 31%, MUFA from 37 to 40%, and PUFA from 29 to 34%.…”

The sago grub (Rhynchophorus bilineatus) [Montrouzier, Coleoptera, Dryophthoridae] is a local delicacy in the Papua Province in Indonesia. In this study, the nutrient content of the edible insect was measured using chromatographic and spectrometric methods. The results showed that it contains 10.39 g protein and 17.17 g oil/ 100 g fresh weight. The sago grub meets the FAO/ WHO requirements of 40% essential amino acids and a 0.60 ratio between essential to non-essential amino acids. Its limiting amino acid is methionine + cysteine. The major fatty acids found in the sago grub are palmitic (42%), oleic (45%), and linoleic (3%) acids. Although vitamin E is exclusively produced by photosynthetic organisms, a gram of sago grub oil contains 51 μg vitamin E, which is composed mainly of tocopherols (92%). In contrast with palm oil, the sago grub oil contains δ-tocopherol (0.12 μg/g oil), and a significantly high amount of β-tocopherol (3.85 μg/g oil). It is a source of zinc and magnesium and contains safe levels of heavy metals. Based on these nutritional properties, the Indonesian sago grub can be considered as a good source of nutrients, and its propagation and utilization should be encouraged especially in other areas of Indonesia and maybe in neighboring countries where they are also endemic, and where malnutrition is prevalent. The consumption of edible insects should be considered as a component of dietary diversificationa sustainable way of alleviating the nutritional status of the population.

“…Rearing insects for mass consumption is increasingly sparking interest due to their high nutritional value and, most importantly, their resource efficiency when converting organic matter, especially waste, into protein [6][7][8][9] . As recently reviewed by Dicke 10 , insect production has a much smaller ecological footprint in terms of land and water use and greenhouse warming potential compared to the production of chicken, pigs and cattle which is related to its much lower feed to meat conversion ratio.…”

Rearing insects is expected to dramatically increase during the next few years, and this will be associated with generating high quantities of frass (insect excreta). It is necessary to find solutions allowing the efficient valorization of these by-products before a major upscaling of the industry takes place. therefore, this study aims at investigating the fertilizer potential of frass. A pot experiment was established and soil was amended either with mealworm (Tenebrio molitor L.) frass (10 Mg ha −1 ), with mineral fertilizer (NPK) at equivalent nutrient level to frass or with a mixture of 50% NPK and 50% frass. Changes of soil properties and growth and nutrient uptake by barley (Hordeum vulgare L.) were then analyzed. Due to its rapid mineralization and the presence of nutrient in a readily-available form, we found that frass is as efficient as mineral NPK fertilizer to improve biomass and N, P and K uptake by barley. Compared to mineral fertilizer, water soluble P concentration is five times lower in the presence of frass, which prevents p from loss and sorption onto soil constituents. More importantly, BioLoG ecoplate reveals that addition of frass stimulates soil microbial activity, especially when it is mixed with mineral fertilizer, suggesting a synergistic effect between both amendments. Taken together, our results indicate that frass has a great potential to be used as a partial or a complete substitute for mineral npK fertilizer. this is especially relevant in the context of a reduced availability of mineral fertilizers while being consistent with circular economy's principles.

“…Various insects and other substances such as defatted marine microalgal biomass have received greatest attention, although very little research has been conducted with ruminant livestock. Recent reviews in the area of novel protein sources include Lum et al (2013), Makkar et al (2014), Anankware et al (2015), Stamer (2015), Akhtar and Isman (2018), and de Castro et al (2018).…”

Recent research of feeding practices and the nutrition of lactating dairy goats

Dairy goats can mobilize considerable body fat for support of milk production, but this can necessitate a high nutritional plane later for replenishment. Tissue mobilization during gestation should be controlled so as not to impair lactational performance. Dairy goats can markedly vary feeding behaviour in response to factors such as restricted periods of access; however, further studies are needed to address the efficiency of production. With some tolerance of goats to plant secondary metabolites and voluntary consumption of a wide array of materials, regionally available byproducts and other nonconventional feedstuffs can be used to minimize production costs. Dairy goats are resilient to moderately harsh environmental conditions, but more extreme ones should be addressed with anticipated future climate change. Some differences in the effects of dietary inclusion of fats and oils between dairy goats and cattle may relate to ruminal microbial conditions as well as the susceptibility of mammary gland enzymes to bioactive conjugated linoleic acid isomers. Much research is being conducted to improve the fatty acid composition of fat in goat milk in regard to effects on human health through the use of fats and oils as well as plant secondary metabolites, and effects on antioxidant status are increasingly being considered as well.
