“…Milk urea nitrogen was significantly lower in the LY group (P 00.001). The decrease in urea level in milk and blood (Table 5) was probably related to a higher microbial activity and higher incorporation of NH 3 into microbial protein (Erasmus et al 1992;Masˇek et al 2008;Heidari Khormizi et al 2010). Increasing NDF apparent digestibility approved this hypothesis (Table 3).…”

“…In some studies, supplementation of a culture of S. cerevisiae did not improve milk yield (Putnam et al 1997;Robinson and Garrett 1999;Soder and Holden 1999;Dann et al 2000;Schingoethe et al 2004;Heidari Khormizi et al 2010). However, some other researchers showed a beneficial effect of yeast supplementation on milk yield (Piva et al 1993;Wohlt et al 1998;Nocek and Kautz 2006;Bruno et al 2009;Moallem et al 2009).…”

Effects of live yeast supplementation on mid-lactation dairy cows performances, milk composition, rumen digestion and plasma metabolites during hot seasonFifty-six Holstein cows (36 multiparous and 20 primiparous), that averaged 145923 days postpartum, were used to investigate the supplementing of live yeast (LY) on productivity during hot summer conditions, from July until August 2010. Cows were fed a control diet with or without 4 g of LY (15 )10 9 CFU/g) per cow daily during a five-week period. Cows were milked three times a day and milk yield was recorded daily. Milk samples were also taken weekly for milk composition analysis. Blood samples and rumen liquor samples were taken in two subsequent days during the last week of the experiment. Milk production, 3.5% fat-corrected milk, and DM intake were similar for cows fed on both diets. A greater milk fat percentage was observed for cows fed LY compared to the control (PB0.05). However, milk urea nitrogen concentration in cows fed LY was lower compared to the control (PB0.01). Cows fed LY had greater blood glucose compared to the control (P B0.01). Blood urea nitrogen was lower for cows fed LY compared to the control (P B0.05). Non-esterified fatty acids, bhydroxybutyrate (BHB), triglyceride, total protein, and total cholesterol were similar for both diets. The apparent digestibility of NDF was greater for cows fed LY compared to the control (PB0.05). Rumen parameters such as pH, N-NH 3 , and VFAs were also similar for both treatments. The present results suggested that feeding LY to mid-lactation Holstein cows during heat stress can increase diet cell wall digestibility and improve milk fat percentage.

The study aimed to investigate the effects of a yeast/lactobacillus product, 'ZooLac Bovimix Milk', on the performance and health of Jersey heifer calves during the first month of life. The product contained live yeast (Saccharomyces cerevisiae) and postbiotic from Lactobacillus acidophilus. Danish Jersey heifer calves (n = 148) at birth were randomly allocated to a control diet (CON; 76 calves) or a diet supplemented with the yeast/lactobacillus product in the milk replacer (PRO; 72 calves). The average birth weight was 25.5 ± 0.3 kg and 25.4 ± 0.3 kg for CON and PRO groups, respectively. The yeast/lactobacillus product constituted 0.7% dry matter (DM) of the milk replacer for PRO group. Faecal samples were collected from 40 calves of each treatment around days 6-8 and 25-28, while blood was sampled from all calves around days 2-4 and 26-28. Additionally, 30 other faecal samples were obtained from some calves treated for diarrhoea. Significantly higher growth performance was observed in PRO group animals than in CON group ones, while no effect was found in the number of antibiotic treatments. The DM-% in manure from PRO group tended to be higher than for CON. Causative agents of diarrhoea were either Cryptosporidium spp., rotavirus A or both. Serum metabolites were unaffected by the treatment, however CON group tended to have a higher IgA level. Thus, supplementation of the yeast/lactobacillus product into the milk replacer during the first month of life had a positive effect on calf growth performance but did apparently not affect the overall health.

“…Bassiouni et al (2010) observed that the supplementation of corn silage or berseem hay with cellulase increased the digestibility of nutrients and thus increased milk production. HeidariKhormizi et al (2010) according to reports, in Holstein Holstein cows, feeding direct-fed microorganisms and feeding enzymes or both significantly improved milk production. Feeding FENZ in the Bermuda grass-based TMR increased milk production of dairy cows (Romero et al, 2016) due to improving the digestion of dietary fiber, adding a mixture of cellulase and xylanase at the amount of 1.5 g/kg DM TMR can significantly increase the average daily milk production and FCM production of Murrah buffalo (Chandra Sekhar et al, 2010).…”

Twenty dairy buffaloes at late pregnancy and in 2-4 parties were divided into four groups fed control ration (G1), or the control ration with 10 g yeast (YC)/h/d (G2), 10 g/h/d fibrolytic enzyme (FENZ, G3) and 10 g YC+10 g FENZ/h/day (G4). The feeding period lasted from three months pre-partum up to 100 days postpartum. Results indicated that digestibility of DM, OM, CP, feeding values as TDN and DCP, actual and 7% FCM milk yield, percentages and components yield of milk and feed efficiency improved (P<0.05) by all treatments. Plasma total proteins, albumin, globulin and glucose increased (P<0.05) by FENZ. Ruminal pH value decreased insignificantly, while total volatile fatty acids and ammonia-N concentrations increased (P<0.05) with YC and FENZ. Supplementation with FENZ improved (P<0.05) calf birth weight (CBW), CBW/post-partum dam weight, weight at weaning, and daily and total gain. Reproductive traits improved by FENZ supplementation, in terms of decreasing (P<0.05) duration of placental drop and uterine involution, 1st heat incidence, days open and number of services per conception. Supplementation of YC and FENZ decreased (P<0.05) the cost of kg 7% FCM, and increased (P<0.05) income of 7% FCM, reflecting the highest economic feed efficiency.Pre-and post-partum diets supplemented with yeast culture and fibrolytic enzyme are beneficial to the digestibility, rumen fermentation, blood metabolites, milk production, feed conversion rate, economic feed efficiency, and postpartum reproductive performance of Egyptian buffaloes and growth performance of their offspring during suckling period.
