飼糧中補充鋅、銅與錳對高溫濕度指數期間荷蘭泌乳牛行動分數與性能表現之影響
Effect of Zn and Cu and Mn supplementation on locomotion score and performance of Holstein cows under high temperature-humidity index
摘要
本試驗旨在探討於高溫溼度指數（temperature-humidity index, THI）下（大於72）飼糧中補充有機鋅、銅與錳對荷蘭泌乳牛之行動分數、乾物質採食量、體重及產乳量之影響。試驗期間為2017年4月至7月份，將24頭泌乳中期荷蘭乳牛依體重、乳量、胎次與泌乳天數逢機分成兩組，分別於基礎日糧中補充0（對照組）及每天每頭補充鋅360 mg、銅125 mg及錳200 mg（試驗組）。試驗期間每月調查包括畜舍環境參數（包括溫度、濕度）與計算溫溼度指數、牛隻乾物質採食量、牛隻行動分數（5分制）、體重與產乳量，試驗進行4個月。試驗結果顯示，試驗期間（4至7月份）牛舍平均溫溼度指數分別為73.9±6.2、79.2±3.9、82.0±3.9及81.5±3.4單位。飼糧補充有機鋅、銅與錳有降低牛隻餵飼後第30、60、90及120天之行動分數，且牛隻乾物質採食量也隨著連續補充有機鋅、銅與錳30、60、90及120天有增加之趨勢。產乳量與體重並未受到飼糧補充有機鋅銅錳產生影響。由上述結果得知，在高溫濕度指數下，於飼糧中補充鋅、銅與錳可能有助改善牛隻乾物質採食量與腳蹄健康之現象。

The purpose of this study was to evaluate the effects of dietary supplementation of organic form of Zn, Cu and Mn on locomotion score, dry matter intake, milk yield, and body weight of Holstein lactating cows under high Temperature- Humidity Index (THI) above 72. From April to July, a total of 24 Holstein lactating cows were randomly divided into two groups according to their body weight, milk yield, parity and days in milk. Cows received diets with adding 0 (control) and 360 mg zinc, 125 mg copper, and 200 mg manganese (head/day) respectively. The barn environmental parameters (including temperature, humidity and calculated THI), feed intake of cattle dry matter, locomotion score (5 points), body weight and milk yield were collected monthly for 4 months. The results showed that the THI in barn from April to July were 73.9 ± 6.2, 79.2 ± 3.9, 82.0 ± 3.9 and 81.5 ± 3.4, respectively. Diet with organic zinc, copper and manganese supplementation decreased locomotion score while dry matter intake was increased with the continuous supplementation of organic zinc, copper and manganese for 30 and 60, 90 and 120 days. Milk yield and body weight were not affected by adding organic zinc, copper and manganese. In conclusion, Diets with organic zinc, copper and manganese supplementation might improve dry matter intake and hoof health of Holstein dairy cows under high THI.
