本研究之目的在探討不同雞種與禽舍型式對雞隻生長和發育之影響,期望瞭解雞隻於不同生長期各部位生長發育之情形。試驗一為不同畜舍和週齡對白肉雞與黑羽土雞生長和發育之研究。試驗採用愛拔益加品系白肉雞3000隻,及商業用黑羽土雞6000隻,公母各半並採用公母分飼,分配至三棟畜舍處理(水簾式肉雞舍、水簾式土雞舍及放牧式土雞舍)。試驗期間飼料及水採任食任飲。雞隻孵化後每畜舍及性別處理逢機挑選180隻雞秤重,之後每週秤重至16週試驗結束為止。從4週齡開始每畜舍及性別處理犧牲3隻雞,以供測定屠體性狀。試驗二為不同畜舍和週齡對烏骨雞生長和發育之研究。試驗採用商業用白絲羽烏骨雞6000隻,公母各半並採用公母分飼,逢機分配至兩棟畜舍處理(水簾式畜舍及放牧式畜舍)。試驗期間之飼養流程同試驗一。試驗三包括兩個部分,第一部分為白肉雞公母分飼與合飼對生長成績之影響。試驗採用艾維因品系白肉雞384隻,公母各半,區分為三處理組(公雞組、母雞組及合飼組),每處理16重複,每重複8隻。試驗期間飼料及水採任食任飲,固定於每週清掃剩料,並計算出隻日攝食量。雞隻於孵化後秤重,之後每週秤重至35日齡為止。第二部分,為探討白肉雞公母分飼與合飼對生長和發育之影響。試驗採用艾維因品系白肉雞3000隻,公母各半,逢機分配至兩棟畜舍處理(水簾式畜舍及開放式畜舍),並區分為三處理組(公雞組、母雞組及合飼組),每處理500隻。雞隻孵化後每畜舍及性別處理逢機挑選50隻(分飼組各挑選50隻,合飼組則每性別各挑選50隻),並套上腳標秤重,之後每週秤重至35日齡為止。於8日齡開始每週犧牲4隻雞至29日齡為止,以供測定屠體性狀。試驗期間之飼養流程同第一部分。
試驗一結果顯示,在週增重方面,以白肉雞增重顯著較黑羽土雞為佳;黑羽土雞飼養在水簾式畜舍增重較放牧式畜舍為佳(P < 0.001);在性別方面則以公雞增重顯著大於母雞(P < 0.05)。各部位生長發育方面,以白肉雞具有較高之胸肉、腹脂和肝臟比例;黑羽土雞具有較高之翅膀、腿、心、砂囊、脫皮砂囊、頭、雞冠、肉垂和腳比例(P < 0.001)。性別方面,母雞具有較高之胸肉、腹脂和肝臟比例(P < 0.001),其餘各部位比例以公雞具有較高之趨勢。週齡方面,不論白肉雞或黑羽土雞皆以內臟器官(心、肝和砂囊)發育最早,其次為肌肉(胸肉和大腿肉)之發育,最後則是腹脂之蓄積。肌肉強度方面,白肉雞與黑羽土雞飼養在相同週齡下其肌肉強度並無顯著差異(P > 0.05);黑羽土雞以飼養在放牧式畜舍其胸肉強度顯著高於水簾式畜舍(P < 0.05)。肌肉保水性方面,白肉雞腿肉保水性較黑羽土雞為佳(P < 0.05);黑羽土雞飼養在水簾式或放牧式畜舍間對肌肉保水性並無顯著差異(P > 0.05)。血液生化分析方面,白肉雞之鎂離子及肌酸激酶濃度顯著高於黑羽土雞(P < 0.001),而黑羽土雞之鈣離子、鐵離子及三酸甘油酯濃度顯著高於白肉雞(P < 0.05);黑羽土雞飼養於水簾式畜舍,其鉀離子、磷離子、膽固醇及三酸甘油酯濃度顯著高於放牧式畜舍(P < 0.05),而放牧式畜舍之肌酸激酶濃度顯著高於水簾式畜舍(P < 0.001)。
試驗二結果顯示,烏骨雞在週增重方面,以水簾式畜舍增重較放牧式畜舍為佳(P<0.05);性別方面則以公雞增重顯著大於母雞(P < 0.05)。各部位生長發育方面,以水簾式畜舍具有較高之腹脂比例(P < 0.01)。性別方面,母雞具有較高之胸肉、腹脂和肝臟比例(P < 0.001),其餘各部位比例以公雞具有較高之趨勢。週齡方面,隨週齡之增加各部位生長發育情形與試驗一相似。肌肉強度與保水性方面,其結果與試驗一相似。血液生化分析方面,烏骨雞飼養於水簾式與放牧式畜舍間並無顯著差異(P > 0.05)。
試驗三之第一部分顯示,生長成績方面,均以公雞組與合飼組顯著較母雞組為佳(P < 0.01)。第二部分顯示,就試驗全期週增重而言,公雞以分飼組增重高於合飼組,母雞以合飼組高於分飼組(P < 0.001)。各部位生長和發育方面,採用公母分飼與合飼除了在公雞雞冠與睪丸重量以合飼組顯著大於分飼組(P < 0.05)之外,其餘屠體各部位均無顯著差異(P > 0.05)。肌肉強度與保水性方面,其採用公母分飼與合飼處理組間並無顯著差異(P > 0.05)。
整個試驗研究中顯示,以肌肉產量,睪丸和卵巢成熟度及肌肉強度之觀點,建議飼養於水簾式畜舍之白肉雞於7-8週齡出售;黑羽土雞飼養於水簾式畜舍之公雞與母雞分別於13週齡與13-14週齡出售;放牧式畜舍之公雞與母雞分別於12-14週齡與12-15週齡出售;另外,烏骨雞飼養於水簾式畜舍之公雞與母雞皆於12-13週齡將雞隻出售;放牧式畜舍之公雞與母雞分別於13-14週齡與13-15週齡出售。白肉雞採用公母分飼與合飼方面,以公雞增重較母雞快,建議採用公母分開上市。綜合運用上述各項觀點於商業上,可得較佳之經濟效益。
The purpose of this research were to study the effects of breeds and types of housing on the growth and development of chickens, to understand chickens growth and development during the growing period. Experiment one was to study the effect of different houses and ages on growth and development of broilers and native chickens. There were 3000 Arbor Acre’s broilers, and 6000 native chickens, half male and half female, rearing sexes separately, distributed to three treatment houses (broiler house with wet pad cooling system, native chicken house with wet pad cooling system, native chicken with open designed house). Feed and water were provided ad libitum during the experiment. After hatched, 180 chicks were randomly choose to weigh and record in each house and sex treatment. The chicks were weighed once per week until 16 weeks old. There were 3 chicks slaughtered from 4th week to 16 weeks in each house and sex treatment, and recorded weight data of carcass. Experiment two was to study the effect of different houses and ages on growth and development of commercial silkie bantams. The experiment had 6000 commercial silkie bantams, half male and half female, rearing sexes separately, distributed to two treatment houses (wet pad cooling system house and open designed house). The feed management was the same as experiment one. Experiment three included two parts, the first part was to study the effect of rearing sexes separated and mixed on growth performance of broilers. The experiment used 384 Avain’s broilers, half male and half female, distributed to three treatment areas (male, female, mixed-sex). There were 16 replicates per treatment and 8 chicks per replicate. Feed and water were provided ad libitum during this period. The residue of feed was collected per week, and calculated daily feed intake. After hatched, chicks were weighed, and chick were weighed once per week to 35 days of age. The second part was to study the effect of rearing sexes separated and mixed on growth and development of broilers. The experiment used 3000 Avain’s broilers, half male and half female, and distributed to two treatment houses (wet pad cooling system house and open designed house), and three treatment areas (male, female, mixed-sex). Every treatment had 500 chicks. There were 4 chicks slaughtered and recorded weight of carcass from 8 to 29 days of age in each treatment. The feed management was the same as the first part.
The results of experiments one showed that broilers had significantly better weekly weight gain than native chickens. Native chickens raised at wet pad cooling system house were significantly better weight gain than open designed house (P < 0.001). Males had significantly better weight gain than females (P < 0.05). For growth and development, broiler had high percentage of breast meat, abdominal fat, and liver than native chicken. Native chicken had high percentage of wing, leg, heart, gizzard, gizzard without skin, head, comb, wattle and feet (P < 0.001). Females had high percentage of breast meat, abdominal fat, and liver than male (P < 0.001). Males had high percentage of other spots than females. Broilers and native chickens visceral organ (heart, liver and gizzard) grew most early, next grew the muscle (breast meat and thigh meat), finally was storing up of the abdomen fat. The muscle shear value had no difference on the same week of age of broilers and native chickens (P > 0.05). The native chickens had high shear value on breast meat of open designed house than wet pad cooling system house (P < 0.05). The broilers, thigh meat had high water holding capacity than native chickens’ (P < 0.05). The water holding capacity of muscle of native chickens had no difference on wet pad cooling system house and open designed house (P > 0.05). The analysis of blood biochemistry, the broilers had significantly higher magnesium and creatine kinase concentration than native chickens (P < 0.001). But calcium, iron, and triglyceride concentration of native chickens were more than broilers’ (P < 0.05). The native chickens raised at wet pad cooling system house had significantly more potassium, phosphorus, cholesterol and triglyceride concentration than open designed house (P < 0.05), but open designed house had significantly more creatine kinase concentration than wet pad cooling system house (P < 0.001).
The results of experiment two showed that the weekly weight gain of commercial skilkie bantams raised at wet pad cooling system house was significantly better than open designed house (P < 0.05). Males had significantly better weight gain than females (P < 0.05). The growth and development at wet pad cooling system house had high percentage of abdominal fat than open designed house (P < 0.01). Females had high percentage of breast meat, abdominal fat and liver than those of males (P < 0.001). The other spots of male had high percentage than female. As week old aspect, The weekly growth and development of other spots was the same to experiment one. The results of muscle shear value and water holding capacity were the same to experiment one. There was no difference of blood biochemistry analysis on wet pad cooling system house and open designed house of commercial skilkie bantams (P > 0.05).
The results of experiment three, the first part showed that growth performance of male and mixed-sex were better than female (P < 0.01). The second part showed that at the week’s weight gain aspect, separated male better than mixed-sex male and mixed-sex female better than separated female (P < 0.001). The growth and development of male in mixed-sex had higher comb and testis weights than separated male (P < 0.05), but other spots had no difference (P > 0.05). The results of muscle shear value and water holding capacity were no difference of rearing sexes separated and mixed-sex (P > 0.05).
From all experiments it were concluded that from the point of view of muscle yields, testis and ovary maturation and muscle shear, broilers were suggested sold at 7-8 weeks old. Native chickens raised at open designed house male and female sold at 13 weeks old and 13-14 weeks old, respectively. Native chickens raised at wet pad cooling system house male and female sold at 12-14 weeks old and 12-15 weeks old, respectively. Commercial silkie bantams raised at wet pad cooling system house male and female sold together at 12-13 weeks old. Commercial silkie bantams raised at open designed house male and female sold at 13-14 weeks old and 13-15 weeks old, respectively. Broilers raised sexes separated and mixed, weight gain of males was more than females, therefore suggested to separate raising the male and female until to reach the market weight.
