Abstract: Effective immunity against coccidiosis can be imparted to poultry if the birds are reared on a regular diet containing added viable sporulated coccidia oocysts at a level sufficient only to induce sub-clinical infection. Preferably the oocyst-containing diet is presented to the birds as soon as they are able to ingest solid food, and contains from 10 to 10,000 oocysts per kg of nutrient feed material. The simultaneous administration of an anti-coccidial drug at a curative level can help to control the immunity-producing infection. The oocyst-containing feedstuff of the invention can be prepared using solid free-flowing pre-mixes or aqueous concentrates, containing appropriate numbers of oocysts together with edible thickening agents. The oocysts can be protected against loss of viability through dehydration by being encapsulated. Growth of the immunized birds is sustained even when they are exposed to a severe oocyst challenge sufficient to induce serious infection in unimmunized birds.

Abstract: A process for the recovery of immunoglobulins of high purity and potency from milk, in which process milk is passed through a re-usable immunoadsorbent column comprising an insoluble carrier material to which is bound a low-affinity monoclonal antibody specific to one or more milk immunoglobulins but not specific to any other common constituent of milk, the antibody bind immunoglobulin molecules are released by eluting the immunoadsorbent.

Abstract: The invention provides new catalysts, useful for various hydrogenation reactions, which consist of 5 to 40% (w/w) of nickel upon a transition alumina, in particular gamma alumina support. These catalysts have an active nickel surface area of between 80 and 300, preferably 100-250 m.sup.2 /g of nickel and the nickel crystallites have an average diameter of 1 to 5, preferably 1.5 to 3 nanometers. The nickel crystallites are dispersed for at least 95% in the pores of the alumina.

Abstract: Method for treating fish carcasses for separating flesh from frames and skins by a squeezing action of a pair of contra-rotating rollers between which decapitated and gutted fishes or tail sections of fishes are passed tail first. An apparatus for executing said method comprises at least two pairs of contra-rotatable rollers (209, 210, 212, 213) having parallel upright axes and each having at least a resilient surface, the first pair (209, 210), as viewed in the direction of transport, being at a greater mutual distance than the second pair (212, 213).

Abstract: In a process of preparing blood cell protein and haem by splitting haemoglobin under the influence of an acid and an organic solvent, the haemoglobin is first contacted with methanol and water and/or ethanol under turbulent conditions at a temperature of 20.degree. to 50.degree. C., whereafter the mixture thus obtained is mixed under turbulent conditions with a mixture of organic solvent and acid, preferably hydrochloric acid. The separation of the dispersion obtained is carried out in hydrocyclones and the recuperated organic solvent is at least partly recycled into the process.

Abstract: The invention relates to novel ester lubricants which can be used in combination with a hydrocarbon base fluid. The ester lubricants are mixtures of esters based on a 2-alkyl-substituted propane diol-1,3, a trimethylol alkane (C.sub.1 -C.sub.4), optionally a C.sub.5 -C.sub.15 -ether diol and a mixture of C.sub.6 -C.sub.10 - and C.sub.12 -C.sub.18 -monocarboxylic acids.

Abstract: An aqueous liquid or semi-liquid soap composition, for use for example as a shower or bath product, is in the form of a single liquid phase which is preferably transparent. The composition comprises soap chosen from monoethanolamine soaps, diethanolamine soaps or mixtures thereof, and a thickening agent chosen from C.sub.12 to C.sub.18 fatty acids, C.sub.12 to C.sub.18 fatty acid alkanolamides or mixtures thereof.

Abstract: Perishable goods containing water, especially foodstuffs, are packed aseptically in packages formed from impervious but flexible film and furnished with vents adequate for the escape of vapor during treatment at bake or part-bake temperatures at which goods in the package are pasteurized, the vents remaining open throughout the heating and subsequent cooling thereafter to prevent the package collapsing on the goods. The vents are positioned for security of subsequent closure in a closure seam first made to enclose the goods in the package and are constituted by interruptions in the seam providing a total cross-sectional venting area of more than 2.5 mms.sup.2. The vents are sealed after cooling. The invention is particularly applicable to the packaging of bakers' goods which are baked or part-baked in the package, which is preferably made from laminated polymeric film material.

Abstract: A dry, free-flowing and non-caking material whose lecithin content can be varied over a wide range is prepared by combining an aqueous medium, a lipid phase containing at least 1 wt % lecithin, and a proteinaceous material, such as a soy concentrate, comprising a porous particulate substance which includes at least 30 wt % of a substantially water insoluble protein, and drying the resulting mixture. The free-flowing and non-caking nature of the particulate product is attributed to the porous and rigid structure of the proteinaceous material which permits the lipis phase to be contained in the interstitial spaces present in each particle.

Abstract: The invention relates to a process and a packaging container for the treatment of pupae by means of sterilizing radiation and for the controllable release of the hatched insects. The pupae are packed in the development compartment of the packaging container together with a filler and a coloring matter and are given radiation treatment in this compartment. When the insects hatch, they mark themselves with the coloring matter and move into the storage compartment of the container attracted by the light that shines through openings made for this purpose. This storage compartment is perforated to permit partial or complete opening in order to release the insects.
