Live Yeast

A feeding trial was conducted to evaluate the influence of live yeast culture (Saccharomyces cerevisiae) on milk production, composition, and blood biochemistry of dairy ewes during the machine milking period. The control group (CD) was fed a concentrate mixture and hay and grazed twice daily, while the second (YS3) and third (YS6) groups were fed the same diet supplemented with 3 or 6 g of live yeast culture (Yea Sacc1026), respectively. The treated groups had significantly higher values (p < 0.05) for fat corrected milk (FCM) (1221, 1116 and 940 g/day, for YS6, YS3 and CD group, respectively) and fat-protein corrected milk (FPCM) (1204, 1103 and 931 g/day, for YS6, YS3 and CD group, respectively), while the values for milk yield, fat yield and lactose yield were higher (p < 0.05) only in the YS6 group compared to the CD group. Milk yield values were constantly higher in the YS6 group than in the control group while the values for the YS3 group were more variable during milking. Milk composition was not significantly affected by yeast supplementation with the exception of urea values which were lower (p < 0.05) in the YC6 group. Yeast administration influenced β-hydroxy-butyrate (BHB) values, which were higher (p < 0.05) in the treated groups; and non-esterified fatty acids (NEFA) values, which were higher (p < 0.05) only in the YS6 group compared to the control group. Other blood biochemistry values were not influenced by the treatments. We conclude that supplementation with live yeast culture, under the conditions of our experiment, had a significant effect on the performance and metabolism of grazing dairy ewes during the machine milking period. Based on more constant results, we could recommend the inclusion of live yeast culture (Yea Sacc1026) at 6g/animal/day as appropriate for field conditions.

A study was carried out to assess the effect of live yeast Saccharomyces cerevisiae (Nutriferm™) on milk production at National Cattle Research Program Khumaltar Lalitpur from 19 March 2015 to 15 April 2015. Twenty crossbred cattle were selected randomly and divided into five treatment groups. Each group had four animals arranged in Complete Randomized Design (CRD). Among five treatment groups, treatment (T1) was treated with 0.5 kg/MT of live yeast Saccharomyces cerevisiae (SC) incorporated feed, treatment (T2) with 1 kg/MT SC, treatment (T3) with 1.5 kg/MT SC, treatment (T4) with 2 kg/MT SC and treatment (T5) as control without any live yeast inclusion in feed. Supplementation of the live yeast up to seventh day of the trial had statistically non-significant (P>0.05) effect on average milk yield per cattle between the treatments. Response of the yeast on mean milk yield per cattle between the treatments was found statistically different (P<0.05) on fourteenth day and twenty-eight day of the trial. On fourteenth day mean milk yield of control group (T4) was statistically significant with highest dose rate inclusion T4 only but remained non-significant with the rest of the lower dose rate treatments. With further supplementation of the yeast up to 28th day of the trial results showed the statistically significant effect with lower dose rate T2 as well with respect to control group besides T4. Hence, the result of this experiment indicates that supplementation of live yeast for at least 14 days has role in the enhancement of milk production in crossbred dairy cattle with faster effect by dose rate of T4 treatment.

Abstract A 105-day feed trial was conducted to evaluate the effect of probiotic feed supplement containing Saccharomyces cerevisiae on milk yield and its composition in Holstein Friesian cows. The trial was conducted in the region of Sidi Bouzid in the west of Tunisia. Effects of Saccharomyces cerevisiae have been investigated on eight Holstein Friesian cows randomly divided into two groups of four animals on the basis of age, body weight, average milk yield, and lactation number. The first group was supplemented with 2.5 g/cow/day of probiotic yeast Saccharomyces cerevisiae (2.5 1010 CFU/day) and the second group (control) was without the yeast. The study showed that supplementation with 2.5 g of yeast Saccharomyces cerevisiae per cow per day or 2.5 1010 CFU/day tended (P < 0.06) to increase milk production by 1.1 kg/cow. By cons, there was a significant increase of fat (P < 0.01; 52.8 and 46.9 g/cow/day) and protein (P < 0.05; 41.7 and 38.7 g/cow/day) content both for treated and control group, respectively. It is concluded that supplementation of Saccharomyces cerevisiae at 2.5 1010 CFU/day in the diet of dairy cows may have positive influence on milk fat and protei n yield (g/cow/day).

Bypass protein stimulates the voluntary feed intake, increase quality milk production and thereby improves the economic status of dairy cows farming. This study was conducted to assess the effect of supplementation of bypass protein on lactation performance of dairy cattle. The experiment was conducted by using 2 factorial completely randomized designs. Milk yield of individual animal was recorded daily and milk composition was recorded at fortnight interval. Results revealed that the average daily milk yield of cows fed with Heat treated soyabean cake-T1 (4.29 L) was greater than cows fed with formalin treated soyabean cake-T2 (3.56 L) followed by control group-T3 (2.62 L). . The fortnight average milk protein and fat percentages were 2.91, 2.94 and 3.18% and 5.52, 5.55 and 4.47% for T0, T1 and T2 groups respectively. The weekly average milk SNF and milk density were 8.12, 8.37 and 8.64 % and 25.67, 27.80 and 27.10%, for group T0, T1 and T2 respectively. Experiment revealed that by-pass protein supplementation to lactating animals is one of the option for improving the milk production and milk composition and suggested that further study should be conducted to precise the optimum level of bypass protein supplementation and to quantify the experimental period.

Abstract Milk production is a primary factor controlling weaning weight of beef calves. The purpose of this experiment was to develop a practical and reliable on-farm method of estimating milk production and to relate estimates of milk production and milk composition to preweaning weight gain of calves. A second objective was to relate milk production to postpartum ovarian activity. Milk production of spring- and fall-calving grade Angus cows was estimated by machine milking (MM; average of 66, 123 and 189 d postpartum) and weigh-suckle-weigh (WSW; average of 50, 95, 136 and 179 d postpartum) techniques following overnight calf removal. Cows and calves were weighed monthly and the postpartum interval to first ovulation following calving was determined. The repeatability of the estimated milk production by MM (.97) was higher (P < .01) than by WSW (.35). The correlation of average WSW and average MM estimates of milk production with preweaning calf gain were high and similar (> .75). Inclusion of milk composition did not improve the multiple correlation of MM-estimated milk production and calf gain. Neither milk production in early lactation (−.06) nor prebreeding weight change (−.07) was correlated with postpartum interval to ovulation. Machine milking was a repeatable method of estimating milk production of beef cows and can be used to evaluate effects of management variables on lactation of beef cows.

The aim of the research was to study the effect of the age at conceiving on the productivity traits of sheep from Synthetic population Bulgarian milk in Bulgaria. The experiment was conducted with 20 ewes traditionally conceived at the age of 18 months and 20 ewes conceived as ewe lambs at the age of 11 months on first lactation and their lambs (47) reared in IAS - Kostinbrod, Bulgaria. The 120 days milking milk production and that after 120 days until the end of lactation were determined by the AC method of ICAR. The days after the standard period until the end of lactation were registered. The milk composition was measured by milk analyzer Ekomilk, Bultech Company, Bulgaria. The live weighs were measured. The fecundity was determined. With the exception of the fecundity and the standard 120 days milking milk production the age at conceiving influences significantly the live weigh before conceiving, birth live weight of lambs, the duration of the milking period and the milking milk yield (P<0.01; P<0.001). The traditionally conceived ewes had significantly higher live weight before conceiving (52.31 kg), of newborn lambs (5.05 kg), the duration of milking period (187 days) and milking milk yield (130 L) than the early conceived (40.53 kg; 4.16 kg; 120 days; 80.24 L) (P<0.01; P<0.001). For the fecundity and the standard 120 days milking milk production no significant differences were found between the groups (1.08% and 1.25%; 92.27 L and 80.24 L). Significant difference in the milk composition of the ewes conceived at 18 month age compared to the conceived at the age of 11 months (P<0.05; P<0.001) was found. The obtained results provide useful information for the implementation of suitable management decisions for early conceiving of the ewes from Synthetic population Bulgarian milk for production of lambs and milk at the farm practice.

The Difference

The preliminary study to quantify the drop in milk production in cattle due to cold climate and subsequent nutritional amelioration in temperate Kashmir where the temperature in the winter months ranges from -4 to 10 0C was conducted at Mountain Live stock Research Institute (MLRI), SKUAST-Kashmir and in various dairy farms in the vicinity. In the treatment group, the animals were provided with 150 grams of jaggery and 200 grams of crushed fenugreek daily in addition to normal feeding schedule. The data regarding milk yield and associated parameters were compared between winter (December to February) and spring (March to May) months. The milk yield was recorded daily for 15 days and then presented as an average. The average milk yield in treatment group (6.41±0.53 kg) was significantly (p than 0.05) higher as compared to control group (4.48±0.21 kg) in the winter months. Similarly, the milk yield in the spring months was higher in treatment group (9.12±0.22 kg) as compared to control group (8.68±0.23 kg) but the difference was statistically non-significant. No significant changes were observed in milk composition in winter and spring months in both control and treatment groups. The overall milk production in the treatment group (7.76±0.49 kg) was significantly (p than 0.05) higher in comparison to control (6.58±0.39 kg). Prolactin was higher in treatment group in both winter and spring months but the difference was significant (p than 0.05) in winter months (7.20±0.38 and 5.67±0.13 ng/ml) only. Similarly, growth hormone in treatment group (5.53±0.16 ng/ml) was significantly higher as compared to control group (3.34±0.16 ng/ml) in winter months. Cortisol concentration was significantly (p than 0.05) higher in control group (33.04±0.27 ng/ml) as compared to treatment group (24.33±1.84 ng/ml) in winter months.
