“…Feeding XPY alone increased 4% FCM production by 11% in MP but not PP cows and during mid not early lactation in the present study. The effect of S. cerevisiae on milk production is not always consistent (Martin and Nisbet, 1992) increasing milk production in some studies (Wohlt et al, 1991;Putnam et al, 1997;Schingoethe et al, 2004) but not in other studies (Arambel and Kent, 1990;Higginbotham et al, 1994;Dann et al, 2000), and based on the present results, cow age and stage of lactation may have influenced previous results. Milk fat percentage was lower in XPY and P169+XPY vs. control cows.…”

“…Francisco et al (2002) reported that 4% FCM production in MP cows fed a sorghum-silage TMR without supplemental yeast during the first 12 weeks of lactation was not significantly affected by P169 supplementation (a 1.9% numeric increase). Stimulatory factors for rumen bacteria, such as B vitamins or branched-chain VFA (Higginbotham et al, 1994) and growth factors, such as malate (Nisbet and Martin, 1991) are present in yeast culture, and their absence may have contributed to the lack of milk production response in Francisco et al (2002). Propionibacteria likely increases milk production because of an increased supply of glucogenic precursors caused by changes in rumen fermentation (Kim et al, 2001;Stein et al, 2006).…”

To determine the effect of supplemental feeding of Diamond V-XP yeast (XPY) alone or in combination with propionibacteria strain P169 on milk production, milk components, body weight, days to first and second ovulation, plasma insulin, and plasma and milk glucose, 31 primiparous and multiparous (MP) Holstein cows were fed one of three dietary treatments between 2 weeks prepartum to 30 weeks postpartum: (i) control (n = 10), fed a corn silage-based total mixed ration (TMR); (ii) XPY (n = 11), fed control TMR plus XPY (at 56 g/head/day); and (iii) P169+XPY (n = 10), received control TMR plus XPY plus P169 (at 6 x 10(11) cfu/head/day). After parturition, daily milk weights were recorded, and milk samples were collected twice weekly for milk component analyses. Daily uncorrected milk, solids-corrected milk, and 4% fat-corrected milk production for MP cows fed P169+XPY was 9-16% greater than control MP cows, but these increases were only evident during mid lactation (9-30 weeks). The percentage of milk fat was 8-18% greater in control than XPY and P169+XPY groups. Milk lactose percentage in MP cows fed P169+XPY was 3-5% greater than in control and XPY MP cows. Primiparous and MP cows fed P169+XPY had 28-32% greater milk glucose levels than control and XPY-fed cows. Diurnal plasma glucose concentration was not affected by diet in MP cows. Plasma insulin levels in MP cows fed P169+XPY were 30-34% greater than in other groups of MP cows. Milk glucose and plasma insulin responses to P169+XPY feeding suggest that P169+XPY might have enhanced gluconeogenesis and increased glucose uptake by the mammary gland in Holstein cows. Thus, a combined feed supplement of P169 and XPY may hold potential as a natural feed alternative to hormones and antibiotics to enhance lactational performance.

“…Many workers reported that the supplementation of DFM in ruminant rations has become a generally accepted practice due to increased ruminal digestion, DMI, performance and reduced body temperature (Piva et al, 1993;Higginbotham et al, 1994;McGilliard & Stallings, 1998). Nikkhah et al (2004) and Raeth-Knight et al (2007) have observed non-significant improvement of DMI by animals fed with yeast culture.…”

This experiment was undertaken to evaluate the potential impacts of supplementing two direct-fed microbial (DFM) products, namely Bactozyme and Ru-max, to the diet of 12 male Barki sheep (live body weight 46.6 ± 2.9 kg) on dry matter intake (DMI), apparent total tract digestibility of nutrients, nitrogen balance and rumen fermentation characteristics. The Bactozyme or Ru-max were supplemented at a rate of 1.0 g/head/day, mixed with the concentrate mixture. Animals were randomly allocated into 3 equal groups (n=4) and were subjected to the digestibility trails.The results showed that the inclusion of either products of DFM had no positive impact on DMI, but non-significantly improved the apparent total tract digestibility of dry matter (DM), organic matter (OM) and crude protein (CP). However, the Bactozyme addition increased (P<0.05) the apparent total tract digestibility of neutral detergent fiber (NDF) and acid detergent fiber (ADF). The enhancement of the apparent total tract digestibility of cell wall was not significant for the two of DFM products and a non-significant improvement in cell wall digestion due to the Ru-max supplementation over the control group was found. The DFM products had positive impacts on the average of total digestible nutrients (TDN) and digestible crude protein (DCP) but non significant in comparison with the untreated animals. In addition, the nitrogen balance was improved (P>0.05) by 8 and 13% due to Ru-max and Bactozyme supplementation, respectively in comparison with the control group. The results also revealed that inclusion of DFM products had no impacts on rumen pH 3.0 and 6.0 h after feeding but Bactozyme reduced (P<0.05) the rumen pH 1.0 h after feeding compared to the control group. The inclusion of Bactozyme and Ru-max increased (P>0.05) the NH 3 -N concentration in the rumen at 1.0 and 3.0 h after feeding but the Bactozyme decreased (P<0.05) the NH 3 -N concentration and increased the volatile fatty acids (VFA) at 6.0 h after feeding compared to the control group. Overall, results indicated that the two DFM products had positive impacts on cell wall digestibility, which in turn improves metabolic energy supply and nutrients utilization in ruminants as well.

“…Feeding high-grain diets to ruminants to increase energy density has resulted in negative associative effects on fibre digestion in the rumen. Harrison et al (1988) concluded that rumen fermentation was more stable in dairy cows fed high concentrate diets supplemented with yeast culture than without the supplement, and several studies reported improved performance of dairy and beef cattle fed high-concentrate diets supplemented with yeast cultures (Higginbotham et al, 1994;Mir & Mir, 1994;Olson et al, 1994). Furthermore, inclusion of yeast culture in the diets of dairy cows produced variable responses in tolerance to heat stress (Higginbotham et al, 1994).…”

This experiment was carried out to study the effect of the inclusion of a yeast culture in the diet of feeder dairy calves on their growth and carcass characteristics. Thirty male Friesian calves were randomly allocated to two groups of 15 each (treatment and control). The calves were fed a total mixed ration for a period of 294 days and then slaughtered to obtain carcass measurements. The yeast culture was added to the diet of the treatment group at a level of 20 kg yeast culture/ton of feed. The addition of the yeast culture did not affect final weight, average gain or average daily gain, but reduced total and daily dry matter intakes. Feed conversion ratio was not affected by treatment. Yeast culture supplementation had no effect on fasting weight or cold carcass weight, dressing percentage nor on non-carcass components. Differences in back-fat thickness and in the weight and percentage of carcass cuts were not significant between treatments. Similarly, carcass characteristics and quality measures did not show any significant differences between treatments. In this experiment the inclusion of a yeast culture in the finishing off diet of dairy calves had no effect on their growth rate, feed conversion ratio, carcass characteristics or meat quality. ________________________________________________________________________________
