近年来，人们对驴奶生产、驴奶特性和驴奶养殖技术的兴趣越来越大。驴奶具有经济价值高的特点，但驴奶的生产水平较低。在挤奶过程中，马驹通常与母驴分开，以便在挤奶前将乳汁收集在雌驴的乳腺中。哺乳期驴驹每天需要8小时的禁食期。在此期间，可以应用部分人工哺乳系统（白天人工哺乳，夜间自然哺乳）。这项工作的目的是评估这种创新技术对Martina弗兰卡驴驹体内性能和产肉性状的影响。40只Martina弗兰卡珍妮和它们的小马驹被用于试验。在Colostnim假设后，每天有20匹马驹进行部分人工哺乳（AS），20匹马驹进行自然哺乳（NS）。从8：00到20：00，两组都与母亲分开，以便让珍妮挤奶。AS组在一个配备有自动犊牛哺乳机的畜栏中。每组在12个月时屠宰10匹马驹，在18个月时屠宰10匹马驹。人工哺乳制度对驴驹的生长速度有积极的影响，尤其是在出生后的前6个月，周增重较高（P
In recent years, there has been an increasing interest on donkey milk production, on its characteristics, and also on breeding techniques. Donkey milk is characterized by high economic value, although the productive level of jennies is poor. During the milking process, foals are usually separated from their dams, allowing the milk collection in the mammary gland of jennies before milking session. This takes 8 h per day of fastening period for lactating donkey foals. During this period, it could be possible to apply a partial artificial suckling system (artificial suckling during daytime and natural suckling during the night). The aim of the work is the evaluation of the effect of this innovative technique on in vivo performances and on meat production traits of Martina Franca donkey foals. Forty Martina Franca jennies with their foals were used for the trial. After colostnim assumption, 20 foals were partially artificially suckled (AS) during each day, and 20 foals were naturally suckled (NS). From 8.00 to 20.00, both groups were separated from their mothers in order to allow the milking procedures of the jennies. The AS group was in a stall equipped with an automatic calf-suckling machine. For each group, 10 foals were slaughtered at 12 months and 10 foals at 18 months. Artificial suckling system positively affected the growth rate of donkey foals, particularly in the first 6 months from birth, with higher weekly weight gain (P
