摘要
Abstract
The study aimed to compare the growth performance of crossbred combinations among local chicken breeds,commercial laying hens,and fast-growing broilers.The experiment utilized local chicken breeds(Dagu chickens,Lindian chickens),modern high-yield laying hens(Jinghong No.1 laying hens,Hy-Line Brown laying hens),and fast-growing broilers(Anak-40 broilers)as materials.A two-factor cross design(sire×dam)was adopted to construct four cross combinations:Scheme 1(local breed×commercial layer)included Dagu×Jinghong No.1(DJ group)and Dagu×Hy-Line Brown(DH group);Scheme 2(fast-growing broiler×local breed)included Anak-40×Lindian(AL group)and Anak-40×Dagu(AD group).For each combination,200 healthy chicks were hatched,with equal numbers of males and females.The experimental period lasted 120 days.The results showed that the growth performance of Scheme 2 was superior to that of Scheme 1.The average daily gain in AL and AD groups was significantly higher than that in DJ and DH groups(P<0.05),while the feed-to-gain ratio was significantly lower(P<0.05).The survival rate of offspring in all cross combinations exceeded 90%,with AL group having the highest rate.The feather color uniformity in the two combinations of Scheme 2 reached 100%,whereas white feathers appeared in Scheme 1.The slaughter rate and eviscerated percentage of Scheme 2 were significantly higher than those of Scheme 1(P<0.05).Scheme 1 exhibited a higher leg muscle rate,with DH group(28.3%)being significantly higher than AL group(P<0.05).The meat quality of Scheme 1 was superior,with significantly lower shear force values(P<0.05)and significantly higher contents of inosinic acid and intramuscular fat compared to Scheme 2(P<0.05).The meat color lightness(L* value)of Scheme 2 was significantly higher than that of Scheme 1(P<0.05).The study indicates that the AL combination is suitable for large-scale efficient production,while the DH combination balances leg muscle rate and meat quality,meeting the demand of the high-end market.关键词
