“…Positive effects of inclusion of PRO on growth performance are expected to be accompanied by improvements in feed intake [22]. In the present results, addition of PRO improved the lambs performances by enhancing BW gain, TWG, GR, and reducing FCR in the post-weaning period which a companied by a tendency to increase DM intake.…”

ObjectiveTwo experiments were conducted to evaluate the effects on growth performance, digestibility, and blood metabolites of lambs during pre- and post-weaning period of inclusion of a commercial probiotic (PRO) containing a mixture of two strains of Pediococcus, Pediococcus acidilactici (1×106 colony-forming unit [cfu]/g) and Pediococcus pentosaceus (1.3×106 cfu/g), with dextrose as the carrier compound compared to a diet based on concentrate mixture and wheat straw.MethodsIn exp. 1, 24 male lambs of about 15±2.6 d age and initial body weight (BW) of 5.52±0.6 kg were randomly allocated into three groups. One group received control diet without additives, and remainders received control diet supplemented with 0.5 or 1 g PRO/lamb/d. Daily feed intake and biweekly BW were recorded. In exp. 2, five lambs, (initial BW = 29.72±1.15 kg, age = 6.54±0.32 mo) were used as experimental animals in a digestion trial. They were fed the same diets as in Exp. 1.ResultsThe supplementation of PRO did not result in any significant differences in milk intake, average daily gain (ADG), or total gain between treatments during the pre-weaning period. Total dry matter intake tended to be greater (p = 0.07) with addition of PRO in the post-weaning diets. During post-weaning phase, the final BW, ADG, total gain, and feed conversion ratio of the lambs receiving PRO treatments tended to be greater (p≤0.10) than the control group. Addition of PRO in post-weaning diet decreased (p≤0.01) blood urea and cholesterol concentrations. With the exception of ether extract digestibility, all nutrients digestibility were improved with inclusion PRO in the post-weaning diets.ConclusionLambs that received PRO in post-weaning diet appeared to show a better performance than lambs in pre-weaning period. Addition of the probiotic in the post-weaning diet trended towards improved dry matter intake, growth performance, feed conversion ratio, and nutrients digestibility.

“…In contrast to the results of this experiment, a study with goat kids (Ata o lu et al, 2010) showed that kefir consumption did not affect fecal consistency. However, our findings may partially be supported by findings of a recent meta-analysis by Signorini et al (2012), who reported a lower incidence of diarrhea in lactic acid bacteria-fed calves and attributed the response to the indirect or direct modulation of the endogenous microbiota or the intestinal immune system by probiotics.…”

A growing body of evidence suggests health-promoting effects of kefir consumption on different nonruminant species, leading to the speculation that kefir may act as a probiotic and benefit calf performance and health. Our objectives were to determine effects of feeding kefir on performance and health of calves in the first 70d of life. Thirty 3-d-old female Holstein calves (body weight=38.2±3.1kg) were blocked by initial body weight and assigned randomly to 1 of 3 treatments (1 calf per pen; 10 pens per treatment). Kefir was added to whole milk (vol/vol) at 0:1 (control; KF0), 1:3 (KF1), or 1:1 (KF2) and fed twice per day (0800 and 1600h) from d3 through 45 and then once per day until weaning, which occurred on d50. Pre- and postweaning intake of starter, daily body weight gain, and gain-to-feed ratio exhibited no difference among treatments. Adding kefir to whole milk fed directly to calves had no effect on concentration of blood metabolites collected on d20, 40, and 70. Body length on d50 (weaning) and 70 was greater in kefir-fed calves. Kefir intake improved fecal scores and reduced days with diarrhea during the first 2wk of life. Apparent digestibility of organic matter, ether extract, crude protein, and neutral detergent fiber remained unaffected by treatment. Overall, it appears that directly feeding kefir to calves during the preweaning period did not improve the performance of calves under the conditions of the current study; however, its consumption marginally improved body length and fecal consistency in the first weeks of life, which is an important concern in intensive calf-rearing systems. Feeding kefir to neonatal calves may be a viable approach to improve the health of calves in commercial calf-rearing operations, although to validate its health-promoting effects additional research is needed to investigate its effects under different calf-rearing conditions.

“…However, some studies observed that rat body weight gain was similar in both groups (control and kefir); No significant differences were found (Elena et al, 2007;Sahin and Yardimci, 2009;Ataşoğlu et al, 2010;Kızak and Çelik, 2012;Aliakbarpour et al, 2013;Salaj et al, 2013;Piccolo et al, 2015).…”
