Artificial rearing of pigs
I . Baby pigs were removed from the sow 36-48 h after birth and reared on a diet of reconstituted whole-milk powder until 28 d of age. The whole milk was either mildly or severely heated before spray-drying ; the severe heating completely denatured the whey proteins. 2. When the two milks were given at a high level of intake, either at hourly intervals or twice daily, severe scouring and some d...
متن کاملArtificial Diet for Rearing Trichogramma Wasps (hymenoptera: Trichogrammatidae) with Emphasis on Protein Utilization
Trichogramma wasps are tiny hymenopterous egg parasitoids widely used in biological control programs worldwide. The huge quantities of insects necessary for inundative releases are mainly produced on factitious hosts like Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae), or on silkworms. In order to simplify production, increase its flexibility, and potentially reduce cost, studies on arti...
متن کاملRearing the Cotton Bollworm, Helicoverpa armigera, on a Tapioca-Based Artificial Diet
The impact of a tapioca-based artificial diet on the developmental rate, life history parameters, and fertility was examined over five consecutive generations for the cotton bollworm, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), a highly polyphagous pest of many agricultural crops. The study showed that when fed the tapioca-based artificial diet during larval stage, larval and pupal de...
متن کاملArtificial rearing of pigs
I. Diets containing different proportions of skim milk and fat, either beef tallow or soyabean oil, supplemented with fat-soluble vitamins were given to 2-d-old pigs. Each fat source was used in three diets containing approximately 280, 350 and 420 g fat, and 260, 235 and 210 g protein/kg dry matter respectively. 2. The diets were given as a milk containing zoo g solids/l during a 26 d experime...
متن کاملRearing the house fly predator Carcinops pumilio (Erichson) (Coleoptera: Histeridae) on an artificial diet
A number of concentrations of PRO-PLEXTM, a protein rich food additive, were incorporated into an artificial diet to determine its effect on the predatory beetle, Carcinops pumilio (Erichson). The impact of this host-free artificial diet on developmental time, larval weight, oviposition and mortality was assessed. When C. pumilio is fed on a host-free diet, the total development of egg to adult...
