Provided is a ball supply integrated type auto tee-up machine with a simple structure, and more particularly, to an advanced concept technology for easily improving a structure of an auto tee-up machine while performing complexly a function of supplying a golf ball to a golf tee and a function of teeing-up the golf ball on the golf tee by using a single motor. The present invention provides a technique to implement a function of allowing a second ball chute to supply a golf ball to a golf tee and a function of teeing-up the golf ball placed on the golf tee with one-stop automation after delivering the golf ball inserted to a first ball chute to the second ball chute while the golf tee and the first ball chute ascend/descend and the second ball chute descends/ascends in an opposite direction at the same time by using a single tee-up motor.

Provided is a growth supplement for efficient production of agricultural and livestock products, more specifically, a growth supplement for environment-friendly crop cultivation and livestock rearing to increase yields of crops and livestock, which is prepared by mixing specific amounts of antibiotic fruit juices, one or more sources of sugar, one or more sources of hydrogen carbonate, one or more sources of chloride ion and antifebrile vegetable juices depending on crops (species) and cultivation (livestock) conditions to feed the livestock or crops. The growth supplement is prepared by admixing and stirring antibiotic fruit juices in an amount of 2 to 10 parts by weight; the source of hydrogen carbonates in an amount of 1 to 4 parts by weight; the source of chloride ion in an amount of 1 to 4 parts by weight; and antifebrile vegetable juices in an amount of 2 to 8 parts by weight, based on 100 parts by the source of sugar.
