Chickpea (Cicer arietinum L.) is an alternative protein source that can be used to substitute soybean meal (SBM) in diets for young turkey. Raw chickpea seeds (RCKP) have a low content of anti–nutritional factors (i.e., trypsin inhibitor) compared with peas, common beans, and soybeans, offering alternative to extrusion. Depending on the variety, it would facilitate farmers to add RCKP on-farm diets. The objective of this study was to investigate the effect of RCKP (cv. Burnas) use in diets with or without phytase addition on growth performance, carcass traits, bone mineralization, and plasma profile of young turkeys (1 to 70 D of age). A 4 × 2 factorial design was performed to compare the efficacy of four levels of RCKP (0, 80, 120, and 240 g/kg, replacing SBM) and two levels of enzyme added (0 or 0.2 g/kg diet). The results showed that BW gain was significantly increased with increasing amounts of RCKP in the diet but the feed intake and FCR were not affected. Carcass yield, breast and legs yield, internal organ weight, and tibia traits were not affected by feeding RCKP diet but cecal digesta pH was significantly increased. Phytase addition had beneficial effects on growth performance and tibia mineralization but did not affect the carcass traits. The plasma analytes were not affected by feeding RCKP, except for triglycerides, total bilirubin, phosphorus, and iron. It can be concluded that RCKP can be used as an alternative protein source to replace SBM in heavy-type turkey diets, at inclusion levels up to 240 g/kg.

饲喂生鹰嘴豆(Cicer arietinum L.,cv。Burnas)日粮的微生物植酸酶对肉仔鸡生长性能,car体性状,骨矿化和血液生化参数的影响

鹰嘴豆(Cicer arietinum L.)是一种替代蛋白质来源,可用于代替年轻火鸡饮食中的豆粕(SBM)。鹰嘴豆生种子(RCKP)与豌豆,普通豆和大豆相比,抗营养因子(即胰蛋白酶抑制剂)的含量低,可以替代挤压食品。根据品种的不同,这将有助于农民增加RCKP农场饮食。这项研究的目的是研究在添加或不添加植酸酶的日粮中使用RCKP(cv。Burnas)对年轻火鸡(年龄1至70 D)的生长性能,car体性状,骨矿化和血浆分布的影响。进行了4×2析因设计,以比较四种水平的RCKP(0、80、120和240 g / kg,代替SBM)和两种水平的酶(0或0.2 g / kg饮食)的功效。结果表明,随着日粮中RCKP含量的增加,体重增加显着增加,但饲料摄入量和FCR却没有受到影响。体产量,乳房和腿部产量,饲喂RCKP日粮不会影响内部器官重量和胫骨性状,但盲肠消化液的pH值会显着增加。添加植酸酶对生长性能和胫骨矿化有有益影响,但不影响the体性状。除甘油三酸酯,总胆红素,磷和铁外,血浆分析物不受饲喂RCKP的影响。可以得出结论,RCKP可以用作替代蛋白源,以取代重型火鸡日粮中的SBM,其包合物含量可达240 g / kg。总胆红素,磷和铁。可以得出结论,RCKP可以用作替代蛋白源,以取代重型火鸡日粮中的SBM,其包合物含量可达240 g / kg。总胆红素,磷和铁。可以得出结论,RCKP可以用作替代蛋白源,以取代重型火鸡日粮中的SBM,其包合物含量可达240 g / kg。
