Hermetia Illucens Larvae

Insects will likely play an important role as protein sources for livestock in the future. Many insect species are able to convert materials not suitable for human nutrition – or even waste – into valuable protein with a favourable amino acid composition for poultry and other livestock. A feeding trial with partly de-fatted meal of dried Hermetia illucens larvae (Hermetia meal) reared on vegetarian by-products of the pasta and convenience food industry was carried out in small groups of Lohmann Selected Leghorn laying hens (four rounds, 10 hens/round). Experimental diets H12 and H24 contained 12 and 24 g/100 g Hermetia meal replacing 50 or 100% of soybean cake used in the control feed, respectively. After three weeks of feeding experimental diets, there were no significant differences between feeding groups with regard to performance (egg production, feed intake). There was a tendency (P=0.06) for lower albumen weight in the H24 group; yolk and shell weights did not differ. No mortality and no sign of health disorders occurred. Plumage as well as wound scores remained stable during the feeding period and did not differ between treatments. Dry matter of faeces increased with increasing proportions of Hermetia meal in the diet, with a significant difference between H24 and the control (P=0.03). An increase of black faecal pads was observed in the H12 and H24 groups. Overall, these results suggest Hermetia meal can be a valuable component of layer diets. However, insect meal production still has to become economically more viable through upscaling production and, especially, legislative issues have to be solved.

Hermetia Illucens Larvae

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.

Behaviour Study

1. A feeding trial is described including four groups of cattle fed on grades I, II and III silages and on swedes, straw and oats respectively.2. The live-weight gains made are recorded, together with the rate of dry-matter intake.3. The efficiency of the dry matter of the diets was calculated.4. All three grades of silage produced a significantly greater rate of fattening than swedes plus straw and oats. There was no significant difference between the fattening values of the three grades of silage.5. The dressing percentages found for 100 silagefed and 71 swede-fed cattle are given. The swedefed cattle yielded a greater average dressing percentage.6. It is suggested that the higher dressing percentage found for root-fed cattle as compared with silage-fed cattle can be attributed to the more rapid elimination of dietary water from the body in rootfed cattle.7. An animal behaviour study is described, the time spent by cattle on the four diets, eating, cudding and lying down, being determined.8. Cattle fed on grass silage spent longer on feeding plus cudding than swede-fed cattle.9. An experiment is described designed to determine the effect of the dry-matter percentage of the diet on the dry-matter intake of ruminants.10. The results indicate that when ruminants are subsisting on a diet consisting solely of succulents, the dry-matter intake is depressed when the dry-matter percentage of the diet falls.

ENERGYANDPROTEIN DIGESTIBILITY OF BROILER CHICKEN CONSUMING MAGGOT (HERMETIA ILLUCENS) MEAL SUBSTITUTING FISH MEAL IN THE DIETS. As an animal feed, maggot from black soldier fly (Hermetia Illucens) has high protein and fat content. Yet, little is known about the digestibility of energy and protein in the diet containing maggot. The present study was conducted to determine the effect of substitution of fish meal with maggot meal in the diets on energy and protein digestibility of broiler chicken. Twenty chicks were assingned to each dietary treatment which was replicated four times in a completely randomized design (CRD). Tretaments were formulated as follow: R0 = 100% fish meal (15% in the diet) + 0% maggot meal (0% in the diet); R1 = 75% fish meal (11,25% in the diet) + 25% maggot meal (3.75% in the diet); R2 = 50% fish meal (7.5% in the diet) + 50% maggot meal (7.5% in the diet); R3 = 25% fish meal (3.75% in the diet) + 75% maggot meal (11.25% in the diet); and R4 = 0% fish meal (0% in the diet) + 100% maggot meal (15% in the diet). Parameters measured were energy and protein digestibility. Energy and protein digestibility were calculated using the indicator (internal lignin) method. All data was submitted to the ANOVA procedure for completely randomized design. Differences were considered significantat (P< 0.05). The results showed that dry matter, energy, and protein digestibility were increased significantly (P < 0.05) compared to R0, R2, R3, and R4. No significant difference (P > 0.05)  were found among R0, R2, R3, and R4. It can be concluded that the maggot flour is best used to the level of 25% replacing fish meal or 11.25% in the ration. However, the result of this study indicate that maggot flour can be used up to 100% replace fish meal in broiler chicken rations without any negative effect on digestibility of dry matter, energy, and protein. Keywords: Fish meal, maggot (Hermetia Illucens) meal, energy and protein digestibility.

ABSTRACT Feed shortage during the dry season in the highlands of Madagascar negatively impacts the dairy cattle productivity, as well as the farmers’ income. Bamboo can produce a high quantity of biomass and could be an alternative way to increase the fodder supply for cattle. The present study aimed to assess the compositional information and the optimal rate of bamboo as fodder for dairy cattle. Leaf samples from nine bamboo species were collected to determine their chemical composition and nutritive value. A feeding experiment was also conducted using ten dairy cows, over ten weeks. Bamboo leaves were mixed with maize silage in five proportions: SIL0:BAM100, SIL25:BAM75, SIL50:BAM50, SIL75:BAM25 and SIL100:BAM0. The contents of dry matter, total ash and crude protein in the bamboo leaves were, respectively, 44.5-64.6 %, 6.68-18.5 % and 7.71-15.4 %. In the feeding trial, the dry matter intake of bamboo leaves was 1.6-7.1 kg per day, with an average of 4.8 kg per day. The dry matter apparent digestibility of bamboo leaves was 37.4-56.4 %. The milk production reached 13.6-14.4 L per cow, per day, but there was no significant difference concerning the rate of bamboo leaves in the mixed diet (p > 0.05). The introduction of bamboo leaves into the ruminants diet did not affect their milk production.

UTILIZATION OF MANURE DEGRADED BY BLACKFLIES LARVAE (HERMETIA ILLUCENS L) ON THE PERFORMANCE OF LAYING NATIVE CHICKEN. Native chicken is one of the livestocks that have been widely used for source of protein. It has already been maintained everywhere in Indonesia. Native chickens is widely kept for eggs because it contains good nutrients for human beings. One of the source of rations for native chicken is manure flour from the degradation of the blackflies larvae (MHD flour). This feed material contains a good nutritional value for this chicken. In this study the results of the degradation of manure blackflies larvae processed into flour and added into the rations with the aim to know the consumption of rations, egg production and rations conversion of native chicken. 40 native chickens females aged 56 weeks had been used.Baterry system cages of 50x50x75 cm in size was used to kept the native chickes. Placement of chicken in each unit was done randomly. A randomized complete design (RAL) with 4 treatment and 5 replications was used as design methods (Steel and Torrie, 1991). Each replication using native chickens age 56 weeks with the following treatments: R0 = 0% flour MHD: R1 = 5% flour MHD: R2 = 10% flour MHD: R3 = 15% flour MHD. The variable measured is the sum of rations consumption, egg production and rations conversion. The results obtained showed that there was highly significant difference (P < 0.01)between treatmentsandrations consumption, egg production, and there was no significant difference (P > 0.05) between treatmens and rations conversion. It can be concluded that as much as 15% of the MHDcan be used in chicken rations. Keywords: Native Chicken, Black Flies, MHD flour.

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01) but no significant difference was recorded for dry matter content of egg yolk at 50% level of egg production (P>0.05). The CP contents of egg albumen and egg yolk differed significantly (P<0.01) at 50% level of egg production but the difference was not significant (P>0.05) for CP content of egg yolk at 75% level of production. There were significant differences (P<0.01) on EE and TA contents of egg albumen and egg yolk at all levels of production. The results of the study demonstrated that the dry matter, as well as crude protein, ether extract and total ash content of eggs on dietary treatment T1(Scavenging + standard ration) was highest compared to the eggs on other treatment groups (T0, T2, T3, T4 and T5).

Acid base homeostasis and urine pH is influenced by the dietary cation anion balance (DCAB) in many species. Here, a negative DCAB acidifies the urine, while higher DCABs alkalize the urine. The dimension of the DCAB effect can be species-specific, because of differences in urine buffer systems. The aim of the present study was to describe the response of laboratory mice to diets with different DCAB. We used 8-week-old wildtype male mice of the C57Bl/6J inbred strain and CD1 outbred stock. Three groups (n = 15 animals/group) were formed and fed standard diet A for adaptation. For the 7-week feeding trial, mice were either kept on diet A (DCAB −7 mmol/kg dry matter (DM) or switched to diet B (246 mmol/kg DM) or C (−257 mmol/kg DM). Urine pH was measured weekly from a pooled sample per cage. There was a significant difference in the basal urine pH on diet A between C57Bl6/J and CD1 mice. The shift in urine pH was also significantly different between the two groups investigated.

Organically produced chicken eggs have more nutritional and sensory properties, and they do not contain any harmful substances to the health of the consumer. Research has shown that, unlike what is expected, there is no significant difference between dry matter, lipid and fatty acids of eggs produced in cages and organic. It has been reported that sold the organic egg about two times fee according to the cage egg has only psychological and ethical motivation. The Council of the European Union considers it necessary for chickens to have access to green roughage materials as well as basal rations in the production of organic eggs. However, if this access is provided, the organically produced egg may respond to consumer expectations. The studies shows that the 4m2 outdoor area allocated per chicken according to Turkey's Organic Agriculture Legislation is not enough to meet these demands. This situation necessitate an increase in the outdoor area separated to the chickens so as to provide rotation with the various plants or the supply of additional green feed materials to the outdoor area. Thus, in addition to obtaining a product with functional food characteristics, a production mode in which animal welfare is increased by the decrease of pecking and cannibalism will be attained. In this review, it is mentioned what applications are increasing the chemical contents such as carotenoids, fatty acids and improving the sensory properties such as color, smell and taste in organic egg production.
