تأثیر مکمل‌های پرو‌بیوتیکی و پری‌بیوتیکی بر عملکرد و سلامتی بره‌های در حال رشد بلوچی

The aim of this experiment was to determine the effects of different microbial products on the performance and health of Baluchi lambs. 40 Baluchi make lamb with mean age of one year and initial body weight of 30 kg ± 1.5 kg for 90 days were used in a completely randomized design with four treatments and ten replicates. Experimental diets were 1) basal diet (control group), 2) basal diet +0.5 gr probiotic, 3) basal diet+2 gr of prebiotic 4) basal diet+0.5 gr probiotic +2 gr of prebiotic per head (sheep) per day. Body weight (BW) and body growth measures were recorded First and period End. Feces were scored weekly. The pH ruminal fluid was determined immediately after sampling and straightening it. The results of this experiment showed that mean BW was higher in probiotic than other groups (52.85). There was no difference between treatments for the final weight, daily gain, feed intake and feed conversion rate. Also, there were no significant differences between treatments in health indicators, fecal consistency and digestibility of nutrients. The results of this study indicated that with use probiotic, pH ruminal fluid was increased and there was a significant difference between the control group (P <0.05). Overall Results of this experiment indicated that supplementation probiotics did not have a significant effect on the performance and health indicators of pre-growing lambs.
