An electronic device for detecting estrus that may be affixed to the tail-head area of a cow is described. This device permits the accurate determination of optimal breeding time, natural or artificial, based on mounting activity. The device includes a water resistant housing, within which is contained the electronic portion of the device consisting of a controller means, a power means, an activation means, a read data means, and at least one display means; said device determining and subsequently indicating suspected and confirmed estrus based on an algorithm. The invention may be used, for example, with any non-human animal exhibiting standing heats and / or mounting behavior indicative of an estrus cycle for making mounting data determinations related to the estrus cycle and analyzing such data to determine optimal time to breed.

The present compounds are intermediates for the preparation of quinoline derivatives and compositions having gonadotropin-releasing hormone antagonistic activity useful as propylactics or therapeutic agent for the prevention or treatment of several hormone dependent diseases, for example, a sex hormone dependent cancer (e.g. prostatic cancer, uterine or cervical cancer, breast cancer, pituitary adenoma), benign prostatic hypertrophy, myoma of the uterus, endometriosis, precocious puberty, amenorrhea, premenstrual syndrome, polycystic ovary syndrome and acne vulgaris; are effective as a fertility controlling agent in both sexes (e.g. a pregnancy controlling agent and a menstrual cycle controlling agent); can be used as a male or female contraceptive, as an ovulation-inducing agent; can be used as an infertility treating agent by using a rebound effect owing to a stoppage of administration thereof; and are useful for modulating estrous cycles in animals in the field of animal husbandry, as agents for improving the quality of edible meat or promoting the growth of animals, and as agents for promoting spawning in fish.

The invention relates to a rhizomyidae traditional Chinese medicine feed reproduction-promoting method, and relates to the technical field of rhizomyidae culturing. The method comprises the following steps: (1) healthy female and male rhizomyidae that never farrow are raised together since they are young, wherein 2-3 females are raised together with 1 male; (2) when male rhizomyidae reaches 45-day old, a nutrition auxiliary feed is used for feeding the male rhizomyidae every day, wherein the nutrition auxiliary feed is prepared by mixing and crushing corn flour, tapioca flour, peanut bran, whole milk powder, unsalted fish meal, animal auxin, wheat germ oil, fried and popped glutinous rice, and Chinese lizardtail herb; (3) when female rhizomyidae reaches 55-day old, an aphrodisiac nutrition feed is used for feeding the female rhizomyidae, wherein the aphrodisiac nutrition feed is a nutrition auxiliary feed which is composed of corn flour, tapioca flour, peanut bran, whole milk powder, unsalted fish meal, glucose and progesterone; and on the last day of feeding, the the female rhizomyidae is subjected to intramuscular injection with 30-50IU of pregnant mare serum gonadotropin. With the method provided by the invention, phenomena of eating and abandoning young rhizomyidae can be minimized, litter size is large, breeding rhizomyidae sexuality is high, female rhizomyidae estrous cycle is short, and rhizomyidae meat quality is good.

A method of determining the phase of an estrous cycle that a mammal is in at a given time that a biological sample is obtained from the mammal is provided. The biological sample obtained from the mammal is combined with at least one flavonoid pigment that reacts with the biological sample on a hydrophobic surface to provide a color response. The estrus phase of the estrous cycle has a corresponding color response that is distinguishable from the color response of each other phase of the estrous cycle to an unaided human eye. The corresponding color response is correlated to the estrus phase of the estrous cycle.

The invention discloses a breeding method for replacement gilts obtained after long x big and big x long binary hybridization. According to the method, four key control points in the breeding processof the replacement gilts are mainly involved and comprise the best mating day age, adaptive weight, an estrus induction method (stimulation on boars) for the replacement gilts and the time length anddaily ration protein / lysine standards for the replacement gilts; if mating is too late, not only is the breeding cost high, but also the breeding performance of the replacement gilts in the whole life can be influenced; the mating replacement gilts the weight of which is lower than the adaptive weight give birth to few live piglets in the first farrow and are easily eliminated prematurely; the problem of difficult estrus of the replacement gilts is solved, and meanwhile the working efficiency of personnel is greatly improved; a nutrient regulation method is adopted for controlling the weightof the replacement gilts in the most suitable stage at the best mating day age and in the best estrus cycle under the free foraging condition. The breeding method can fully exert the production potential of the replacement gilts in the whole life and can also prevent the gilts from premature elimination.

The invention discloses sow aphrodisiac powder which comprises the following components in parts by weight: 10-20 parts of ginkgo leaves, 5-10 parts of raspberries, 2-8 parts of herba epimedii, 1-5 parts of astragalus membranaceus, 10-20 parts of rheum officinale, 2-8 parts of codonopsis pilosula, 5-10 parts of glossy privet fruits, 1-5 parts of radices sileris, 1-5 parts of white atractylodes rhizome, 10-20 parts of caulis spatholobi, 5-10 parts of hairyvein agrimony, 2-6 parts of lithospermum, 2-8 parts of polygonum multiflorum and 1-3 parts of liquorice. The sow aphrodisiac powder is prepared from various Chinese herbal medicines according to physiological characteristics of a sow, the components are synergistic to achieve a remarkable aphrodisiac effect, the oestrous cycle of the sow can be shortened, the fertility rate of the sow can be increased, the body quality of the sow can be improved, and the health of the sow is facilitated.

A gonadotropin-releasing hormone antagonistic composition, which comprises an optionally substituted condensed-bicyclic compound consisting of a homo or hetero 5 to 7 membered ring and a homo or hetero 5 to 7 membered ring is effective as a propylactic or therapeutic agent for the prevention or treatment of several hormone dependent diseases, for example, a sex hormone dependent cancer (e.g. prostatic cancer, cancer of uterine cervix, breast cancer, pituitary adenoma), benign prostatic hypertrophy, myoma of the uterus, endometriosis, precocious puberty, amenorrhea, premenstrual syndrome, pplycystic ovary syndrome and acne vulgaris; is effective as a fertility controlling agent in both sexes (e.g. a pregnancy controlling agent and a menstrual cycle controlling agent); can be used as a contraceptive of male or female, as an ovulation-inducing agent of female; can be used as an infertility treating agent by using a rebound effect owing to a stoppage of administration thereof; is useful as modulating estrous cycles in animals in the field of animal husbandry, as an agent fro improving the quality of edible meat or promoting the growth of animals; is useful as an agent of spawning promotion in fish.
