中文摘要 | 本試驗目的在探討飼糧離胺酸含量對種母土雞產蛋期繁殖性能之影響。以180隻25週齡臺畜12號種母土雞,逢機分配至6個處理組,每處理3重複,每重複10隻種母土雞。試驗飼糧分別含離胺酸為0.38%、0.53%、0.68%、0.83%、0.98%及1.13%,飼糧含粗蛋白質15%,代謝能2750Kcal/kg,飼糧離胺酸之提高係添加L-離胺酸鹽酸鹽。於34~45週齡試驗期間,測定產蛋性能、繁殖性能及種蛋品質等。結果顯示,種母土雞之增種及飼料採食量,以採食0.98%離胺酸處理組顯著較0.38%及1.13%離胺酸處理組者高(P<0.05);隻日產蛋率、飼料換蛋率及種蛋受精率及孵化率,均以餵飼0.38%離胺酸處理組者顯著較其他飼糧處理組差(P<0.05)。活雛數及雛雞重以0.83及0.98%離胺酸處理組較高(P<0.05)。異常雛雞數以0.38及0.53%離胺酸處理組較高(P<0.05)。飼糧離胺酸含量並不顯著影響種蛋的蛋比重、蛋黃重、蛋黃/蛋重百分比及豪氏單位。種蛋蛋重以0.83%離胺酸處理組顯著較0.38%及1.13%離胺酸處理組高(P<0.05)。血清離胺酸含量,隨著飼糧離胺酸含量之增加而呈線性提高(P<0.05),血清中總蛋白及尿酸態氮含量,隨著飼糧離胺酸含量增加而提高,至0.98%離胺酸含量時達到最高(P<0.05)。依活雛數對飼糧中離胺酸含量進行直線迴歸之斷線法統計分析,求得種母土雞產蛋期的飼糧離胺酸最低需要量為0.74%。 |
英文摘要 | This experiment was conducted to study the effects of dietary lysine (Lys) levels on the reproductive performances of the breeders of the Taiwan native chicken during the laying period. A total of 180 pullets of native hens were divided into 18 groups and randomly fed one of six diets. The basal diets contained 15% of CP and 2700 kcal/kg of ME. L-lysine-HCI was added to basal diets to make the dietary levels of lysine to be 0.38, 0.53, 0.68, 0.83, 0.98 and 1.13%, respectively. The laying and reproductive performance of layer and egg characters were determined during the 34 to 45 wks of age. The results indicated that hens fed with 0.98% Lys diet had significantly heavier weight gain and feed intake (P<0.05) as compared with those fed the diets containing 0.38 and 1.13% Lys. The hens receiving the 0.38% Lys diet significantly decreased (P<0.05) egg production, fertility and hatchability of egg and poor feed conversion ration than those of other groups. The number and weight of chicks hatched were significantly increased (P<0.05) from those hens fed the 0.83-0.98% Lys diet. Meanwhile, the number of abnormal chicks hatched was significantly higher in hens fed diet with the 0.38-0.53% Lys diets than those of other groups. There were significantly (P<0.05) heavier of hen fed with the 0.83% Lys diet as compared with those of 0.38% and 1.13% Lys groups. The dietary lysine did not affect the egg specific gravity, egg-yolk, percentage or Haugh unit of egg. A significant increase in serum Lys content occurred as dietary Lys levels were increased (P<0.05). The total protein and uric acid nitrogen in serum were highest in those hens fed the 0.98% Lys diet. The estimated lysine requirement for Taiwan native laying hens by the broken-line method assay based on the number of chicks hatched was 0.74% during the laying period. |
