Abstract :本実験は肥育豚における,成長,血液成分及び枝肉格付けへの制限給水区と自由飲水区におけるアルカリ水給水の効果の検討を目的として行なった。試験動物は240頭のLWHの3元交配種を供試した。制限給水区において,飲水量がいずれも自由飲水区より有意に減少し,同時に採食量も減少させた。また,制限給水区において,アルカリ水区の飲水量と採食量が水道水区より高い傾向にあった。しかし,自由飲水区においては,アルカリ水区は水道区より飲水量と採食量が少ない値を示した。肥育豚の増体量は自由飲水区が制限給水区より高く,また制限給水区と自由飲水区において,水道水区がアルカリ水区より高い傾向を示した。制限給水区のアルカリ水区でグロブリン量が有意に高く,A/G比が有意に低くなった。総コレステロール量,遊離コレステロール量,中性脂肪量及びリン脂質は制限給水区が自由飲水区より低く,制限給水区と自由飲水区において,アルカリ水区が水道区より低い傾向を示した。自由飲水区における水道水区の遊離脂肪酸は他の3区より低い値を示した。枝肉格付けにおける上物率は総肥育豚において,制限給水区におけるアルカリ水区が最も高く,自由飲水区における水道水区が最も低い値を示した。また,雌豚の上物率は制限給水区におけるアルカリ水区で77%と最も高い値を示し,去勢雄の上物率は自由飲水区におけるアルカリ水区で6%と最も低い値を示した。
The experiments were planned to study the effects of Alkaline water in controlled water intake and free water intake on the growth, plasma compositions and carcass judging in fattening hog. Animals tested were 240 baby pigs. Water intake and feed intake were significantly lower in controlled water intake than in free water intake (P<0.01). They intended to be higher in Alkaline water intake than tap water intake in controlled water intake, but intended to be lower in Alkaline water intake than tap water intake in free water intake. Body weight gained by hog was higher in free water intake than controlled water intake, and was higher in tap water intake than Alkaline water intake in controlled water intake and free water intake. In alkaline water of controlled water intake, globlin was higher than others, and A/G ratio was lower than others (P<0.01). Total cholesterol, free cholesterol, triglyceride and P lipid were lower in controlled water intake than free water intake, and intended to be lower in Alkaline water intake than tap water intake in controlled water intake and free water intake. Free fatty acid in tap water intake of free water intake was lower than others. Percentages of the first grade of carcass judging were highest in Alkaline water intake of controlled water intake (first grade : 55.0%), but were lowest in tap water intake of free water intake (first grade : 27.0%) in all hogs tested. In Alkaline water intake, Percentages of the first grade of carcass judging were the highest values (77.0%) in female hog, and were the lowest values (6%) in male hog.
