ABSTRACT
Influence of Yucca and ProBAC s u p p l e m e n t a t i o n on increasing rate of some dimensions in 42-77 day-old Noi chickens
A total of 162 Noi chickens at 42 days of age (108 males and 54 females) were arranged in 3 different treatments witli 3 replicates in which each of them was a pen containing 12 females and 6 males. All cliickens 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 udth Yucca and supplied ProBAC-drinking water in treatment 3. As results, the addition of Yucca or Yucca in combination witli ProBAC sigmficantly improved shank length, breast diameter, thigh diameter, beak length, back length and/or neck length through different stages of age in Noi chicken breed (P<0.05), Further researdies on application of these two bioproducts should be done to evaluate the economic efficiency in clean and safe chicken production system in Vietnam, towards a sustamable agriculture in the future-
Keywords' Noi broilers, pivbiotics. Yucca schidigera, body dimensions.
