Influence of ProBAC supplementation on percent increase of some morphological traits in the 35-63 day-old Noi chickens
The aim ot the ^Uid\ was to determine the effects of ProBAC supplementation (containing 4 differenl strains of B«CJ//»S) on the some measured parametters on live weight in Noi chickens from 35-h3 days old. A total of 96 broiler chicks (4S males and 48 females) v/ere divided into 4 groups in where the control was fed GF1324 and supplied drinking water ad libitum while the others were received 1, 2 or 3 limes/week of ProBAC dnnking water beside given feed. Some dimensions were c-oUected at 35. 49 and 63 days of age. The ProBAC supplementahon has significantly increased the percentage of thigh diameter in females (P=0 04)

ABSTRACT
Effects of ProBAC a n d Yucca s u p p l e m e n t a t i o n on growth performance and feed efficiency in 35-84 day-old Noi chickens
Probiotics and Yucca schidigera are considered as potential biological materials to replace antibiotics and growth stimulants in livestock p r o d u c h o n . In this study, a total of 162 Noi chickens from 35-84 weeks of age were arranged in 3 different treatments with 3 replicates (each of them contains 18 chicks, 6 males and 12 females). Over there, chickens were fed ad libitum (i) GF1324 produced by GreenFeed Vietnam Joint Stock Company in treatment 1, (ii) GF1324 mixed with Yucca in treatment 2 and (iii) GF1324 mixed with Yucca and supplied ProBAC-drinking water in treatment 3 Tlie results were noted that supplementing Yucca in feed in combination with ProBAC in drinking water improved sigmficantly the live weight at 49 days of age (P=0.020), the percent increase ot body length (P=0.001), wings length (PH3.006), thigh length (P=0.001), shank length (P=0.00{1), keel length (P=0.018) and breast diameter (P=0 005) in Noi broilers.
Keywords: Noi chicken broilers, Probiotics, Yucca schidigera, feed conversion ratio, body dimension.
