A system and method for automatically delivering a substance to an animal or fish including a positioning system that positions each animal singularly and a sensor that detects the location of a predetermined targeted area on the animal. The system further includes a delivery device for delivering a substance to the targeted area. The position of the delivery device may be adjustable. The delivery device is in communication with the sensor. The delivery device adjusts its position in response to the data received from the sensor and delivers a substance to the targeted area.

Systems for selecting, generating, and breeding hybrid dairy cattle are described, as are methods for maintaining herds of hybrid cattle.

The present invention relates to methods of and compositions comprising cytokines for, improving the success rate of embryo implantation and the success rate of pregnancy rates in females, by providing an immunopermissive uterine environment prior to insemination or implantation of embryos. The methods of the present invention are used to make the uterus more receptive or less hostile to, for example, transferred embryos, sperm or other allografted tissue.

Disclosed is a method of in vitro fertilization wherein the embryo is implanted into the uterus of a female patient at least two, an preferably three to twelve months after the eggs are retrieved from the patient in order to reduce the effect of autoimmune rejection of the embryo by the patient's autoimmune system and increase the probability and success of pregnancy and wherein prior to embryo implantation, the endometrium in the uterus is prepared for embryo implantation by introducing peripheral blood mononuclear cells (PBMCs) into the uterus. The procedure is combined with cryopreservation techniques to preserve the oocytes or the IVF-produced embryos of the patient.

A first system for determining the relative health of a chick having a first moving platform to support a chick, a first image capture device, a first database having a library of digital images relating to healthy and unhealthy chicks and a computer processor in communication with the image capture device and database. A second system for determining the gender of a chick includes a second moving platform, a second image capture device, stimuli directed at the chick to cause the chick to open its wings. The second system also includes a second database having wing patterns of male and female chicks of the breed of the chick on the second moving platform and a second computer processor in communication with the second image capture device and the second database.
