地面結構對熱季豬隻生長性能及豬舍用水量、廢水量之影響

本試驗旨在探討地面結構對熱季豬舍用水量與廢水量，以及生長肥育期豬隻生長性能之影響。在熱季（6－9月份）將平均體重48kg的LD肉豬72頭，飼養在實地面（SOF組）、部分條狀地面（PSF組）及全條狀地面（TSF組）等3種地面結構豬欄，每處理組4欄，每欄飼養6頭，閹公豬和肉女豬各半數。SOF及PSF組的地面每日沖洗1次，TSF組則不沖洗地面，每3－4日沖洗糞尿溝1次。試驗期間飼糧及飲用水皆任飼，飼養到各組平均體重115kg結束試驗。結果顯示，地面結構對生長肥育期豬隻的採食量和飼料效率皆無顯著影響。飼養於SOF、PSF及TSF的豬隻，在生長期平均沖洗水用量分別為41.60、34.98及17.79 L/d/head，廢水量則為33.87、28.80及16.43 L/d/head。PSF及TSF組的沖洗水用量僅為SOF組的84.09%及42.78%，廢水量則為SOF組的85.00%及48.50%。肥育期平均沖洗水用量為39.51、29.37及13.86 L/d/head，廢水量則為34.65、27.44及13.06 L/d/head。PSF及TSF組沖洗水用量分別僅為SOF組的74.33%及35.09%，廢水量則為SOF組的64.76%及37.69%。綜合上述，在熱季豬舍設置部分條狀地面或全條狀地面，可節省豬舍沖洗水量及減少廢水產量。

The purpose of this study was to investigate the effects of floor types on the water consumption and waste-water quantity of pig house during the hot season, and their the growth performance of grower-finisher pigs. A total of 72 head LD (Landrace ♀ × Duroc ♂) pigs, were assigned to three types of floor pen, inclusive of solid floor (SOF), partially slatted floor (PSF) and totally slatted floor (TSF) when their average body weights were 48 kg during the hot season (from Jun. to Sep.). Each group consisted of four pen replicates of six pigs per each pen, half barrows and half gilts each. The groups of SOF and PSF were washed once daily, and TSF group was washed once every 3 or 4 day. Feed and water were supplied ad libitum. The feeding trial was terminated when the average BW of pigs reached 115 kg. The water consumption and wastewater quantity of pig house, quality of wastewater and their growth performance of pigs were measured. The results showed that the floor types did not affect on average daily feed intake and feed efficiency of pigs. During the growing stage, the water consumption of SOF, PSF and TSF groups were respectively 41.60, 34.98 and 17.79 L/d/head and the waste-water quantity were respectively 33.87, 28.80 and 16.43 L/d/head. The water consumption of PSF and TSF groups were respectively about 84.09% and 42.78% of SOF, and the quantity of wastewater of PSF and TSF groups were respectively about 85.00% and 48.50% of SOF. During the finishing stage, the water consumption of SOF, PSF and TSF groups were respectively 39.51, 29.37 and 13.86 L/ d/head and the wastewater quantity were respectively 34.65, 27.44 and 13.06 L /d/head. The water consumption of PSF and TSF groups were respectively about 74.33% and 35.09% of SOF, and the quantity of wastewater of PSF and TSF groups were respectively about 64.76% and 37.69% of SOF. In conclusion, the pig house installed partially slatted floor or totally slatted floor could decrease water consumption and reduced quantity of wastewater during the hot season.
