Black soldier fly larvae (BSFL) can use food by-products or residues as a growth substrate, and their is considered strategic solution to improve the sustainability efficiency of animal production. BSFL need be reared under controlled environmental conditions, temperature affect welfare bioconversion. The goal this experiment was test different diets: control, vegetable, carnivorous, omnivorous assess effect on larval performance, chemical composition, substrate temperature. (6-days-old)...
We assessed the effects of inhalation administration lavender essential oil (LEO) either once (L1) or twice (L2) a day on animal welfare indicators, carcass and meat quality Italian heavy pigs. Pigs (n = 108) were allotted to three experimental groups (control -C-, L1 L2) was administered, via vaporizer device, treated during entire fattening–finishing period (79–160 kg BW). Tail lesion severity reduced in at end trial compared other (p < 0.05). Body counts, however, higher L2 than C...
Black soldier fly larvae (BSFL) can utilize food by-products or residues for growth, benefiting farm animal’s diets’ production sustainability. The experiment aimed to assess the effect of different substrate compositions on larval chemical composition, and temperature. BSFL were allocated one four diets (control, vegetable, carnivorous, omnivorous) entire (8 days). temperature was measured twice daily using a thermal-imaging camera, accumulated degree hours (ADH) calculated. results showed...
The insect farming sector is expanding, but knowledge of welfare still limited. This article aims to optimize the dietary regime for “black soldier fly” (Hermetia illucens L., BSF) larvae by applying a holistic view welfare. Four diets were tested: control (CONTR, commercial laying hen feed), vegetable (VEG), omnivorous (OMN), and carnivorous (MEAT) diet, conducting experiments at large (2000 larvae) small scale (100 larvae). Rearing parameters calculated including growth rate, substrate...
The large-scale insect rearing sector is expected to grow significantly in the next few years, with Hermetia illucens L. (black soldier fly, BSF) playing a pivotal role. As traditional livestock, it essential improve and ensure BSF welfare. A starting point can be an adaptation of Five Freedoms framework. Feed availability must optimized meet larvae nutritional needs (freedom from hunger) while maximizing substrate conversion efficiency. Similarly, density well-being, particularly...
To date, especially in Europe, few studies have analysed the implications of long journeys on pig welfare and economic losses, expressed terms transport mortality. This study retrospectively data collected from slaughtering registers travel journals a large Italian abattoir. We focused transports coming abroad arriving at slaughter plant after (a total 59,982 pigs over 370 journeys). explored relationship between mortality following variables: country origin, journey duration, astronomical...
The use of phytoextracts has been proposed as a method to improve animal welfare, also in pigs, by reducing stress and anxiety improving performances. Lavandula angustifolia (Miller) essential oil (LaEO) is an interesting calming phytoextract that could be administered inhalation for prolonged periods time help pigs coping with on-farm conditions. aim this study was assess the effects daily vaporized LaEO on pigs' welfare health indicators, nasal microbiota, trying understand whether...
The experiment aimed to obtain information on the water requirements, drinking behavior and motivation of liquid-fed pigs was conducted during hot season. Eighty castrated male (initial body weight: 36 kg) fed a liquid diet (water:feed ratio 3:1), capable guaranteeing fulfilment theoretical were assigned two experimental groups either receiving via nipple drinkers (CON, Control) or having non-functioning available (RW, Restricted Water). availability extra did not affect pigs' growth...
