A memoir in an Okinawa livestock experimental station size domestic animal room

A dosage effect of lumen liquid in a calf for meat .
Laboratory of Okinawa livestock experimental station / size domestic animal room announcement article Okinawa livestock experimental station report 34, 1996.

■ An abstract
The onset of diarrhea decreases when I administer lumen liquid to a black-haired Japanese cow calf of an instar from an instar after life every two weeks on 73rd on 31st, and quantity of increase body improves.
■ A background / an aim
The onset of diarrhea in upbringing device of a calf does not have an influence on a figure after they become stagnation and adult cow of growth, and labor to need for loose bowels measures and economic influence are great. A lactation calf is vulnerable to resistance for illness, and a wear ratio by loose bowels is in particular high, too. Loose bowels protective efficacy of a calf is reported, but the dosage such as lactic acid bacteria examines increase body characteristics and relations with the diarrhea onset because even a farming family administers the ruminant stomach (lumen) liquid which I can apply it to with low cost more.
■ Contents / a characteristic of result
I used eight black-haired Japanese cow calves to an instar from an instar on 86th on 31st and did the ward that I beat and I divided the lumen liquid that I gathered than adult cow into total four times of 300mL on 200mL, the 73rd day on 100mL, the 59th day on 50mL, the 45th day on the 31st day in after birth and administered to 4 with a dosage ward. When I evaluate it and, as a ward comparing four remainder, compare the onset situation of diarrhea with normalcy service 0, soft bowel movement 1, mud service 2, water service 3,

(1) The onset situation of diarrhea of a dosage ward has few 0.21 with 0.07 from contrast ward 0.28 between examination all periods.

(2) The increase weight of the inside has many 2.7kg at 40.7kg a dosage ward 43.4kg, a contrast ward a dosage ward in a study time.

(3) As for the dried foods intake per 1st, a dosage ward is less than a contrast ward except (a 45th instar, 58th instar) for ,Ⅱ period, and an average intake during testing period has few 0.076kg.

The onset of diarrhea decreases, and it is thought that the increase weight improves by administering lumen liquid to a black-haired Japanese cow calf of an instar from an instar from these on 73rd on 31st.

■ Inflection side of result / a point to keep in mind
(1) The onset of diarrhea in a calf decreases, and the increase weight improves, too.

(2) Lumen liquid (a stomach stew) collection device is necessary, and around one or two times exercises are necessary.

(3) You had better administer the lumen liquid after collection within several hours.
