The invention relates to the technical field of animal husbandry, in particular to a synchronous oestrus-timing insemination method suitable for cattle, which comprises the following steps: firstly, performing intramuscular injection of PG (cloprostenol sodium) at different time points after calving to promote uterine recovery and luteolysis and lay a synchronous oestrus foundation; the method comprises the key steps that GnRH (gonadotropin release hormone) is given through intramuscular injection on the 43rd day, the 53rd day, the 60th day and the 69th day, pituitary is promoted to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), collection and screening of follicles are guided, follicle maturation is promoted, the oestrus uncovering rate and the oestrus conception rate are increased, a melatonin implant is implanted in a subcutaneous implantation mode on the 63rd day, and the melatonin implant is implanted in a subcutaneous implantation mode on the 63rd day. The synthesis of ovarian hormones is promoted by regulating the hypothalamus-pituitary-gonad axis, the secretion of follicle cell factors and maturation promoting factors is promoted, the development of granular cells is promoted, and the maturation of oocytes is promoted. According to the method, the pregnancy rate of a double-synchronization-timing insemination scheme which is most widely used in a large-scale dairy cow breeding pasture at present can be remarkably increased, and feasible technical support is provided for success of increasing the breeding efficiency of cows.

Tri -partite devices, kits, and methods (e.g., pull techniques) for subcutaneous implantation of a therapeutic pellet within pre-determined sites in a subject in need thereof are provided. The tri-partite devices are atraumatic devices comprising a cannula barrel, a unitary medication loading system, and a detachable and retractable obturator with or without a coated tip.

The invention relates to the field of medicine, namely to biosensor analytical devices (biosensors) and can be used for continuous minimally invasive determination of blood glucose content. An electrode system for a device for quantitative analysis of blood glucose content comprises a reference electrode (6), an auxiliary electrode (5) and a working electrode (1) a surface of which is modified by a composite material containing a matrix (2) with chitosan covalently linked to an electron transport mediator, and inclusions of the glucose oxidase enzyme (3) placed in said matrix (2), wherein the matrix (2) of the composite material is chitosan-based, the surface of the working electrode (1) with the composite material is covered with a protective diffusion membrane (4), and the electrode system is designed for subcutaneous placement. The technical effect of the invention is to provide minimally invasive continuous determination of blood glucose concentrations within the range of 1.5 to 48 mM.
