Abstract To determine the effect of Certillus on milk production, milk components and feed efficiency, primiparous (n = 13) and multiparous (n = 12) Holstein cows were assigned to one of two dietary groups starting from 8 to 120 days of lactation. The controls (n = 13) received regular TMR ration, and treated cows (n =12) received control TMR plus 2 x 109 cfu/head of Certillus (Church & Dwight Co., Inc., Waukesha, WI). Cows were housed in an open-air free-stall barn with 16 Insentec electronic feeders (8 feeders/group) to record daily feed events and intake (DMI). Cows were provided with ad libitum TMR fed twice daily and were milked twice daily. Milk samples were taken weekly during successive a.m./p.m. milkings and analyzed for percentage milk fat, protein, lactose, and milk urea nitrogen (MUN). Data were analyzed using a repeated-measures 2 x 2 factorial ANOVA. Daily milk production (4%FCM) was influenced (P < 0.05) by treatment x parity, week and parity, averaging 11% greater (P < 0.05) in Certillus-fed than control cows. Milk fat percentage increased (P < 0.005) from 4.02 to 4.41 + 0.09% with Certillus feeding. Milk lactose was influenced (P < 0.05) by week and treatment x parity. Milk protein was affected by week (P < 0.001) only. Certillus decreased (P < 0.05) MUN levels such that MUN was 1.0 mg/dL greater (P < 0.001) in Certillus-fed than control cows. Feed intake was reduced by 9% (P < 0.01) and feed efficiency (kg 4%FCM/kg DMI) was improved by 14% (P < 0.05) in Certillus-fed versus control cows. We conclude that Certillus may hold potential as an effective direct-fed microbial to increase feed efficiency and milk production.

Two feeding regimes were compared using 13 lactating cows (11 Holstein- Fresian and two Brown Swiss) confined in corrals. The rations consisted of a conventional concentrates mixture and sorghum silage in treatment A, and of 22.5 percent sugarcane bagasse mixed with 20.0 percent molasses and 57.5 percent other concentrates (complete ration) in treatment B. The experimental design was a double-reversal with 10-week periods, each divided into a 3-week adjustment and a 7-week comparison phase, preceded by a 25-day preliminary period. During the 7 weeks of the comparison phase of the first of the three experimental periods, five cows on treatment A averaged 37.0 pounds of concentrates and 30.5 pounds of silage consumption daily, while eight cows on treatment B consumed an average of 48.0 pounds of the complete ration. Average daily milk production with these respective rations during the comparison phase in question was 53.1 and 56.9 pounds. No significant differences between treatments were found. Over the three experimental periods of the double-reversal, daily intakes averaged 36.6 pounds of conventional concentrates mixture, 30.2 pounds of silage, and 45.1 pounds of complete ration. On treatments A and B, daily milk production averaged 48.6 and 47.4 pounds; milk fat percentage, 2.85 and 3.23; milk solids-notfat percentage, 9.08 and 9.03; milk total solids percentage, 11.92 and 12.26; milk protein percentage, 3.53 and 3.43; and daily liveweight gain, 1.15 and 1.01 pounds, respectively. The difference between treatment means was significant for milk fat (P < .01) and milk total solids (P < .05) percentages. Since the complete ration resulted in productive performance comparable to that obtained with ad libitum consumption of conventional concentrates, it is concluded that the former is capable of sustaining milk production at nearly maximum capacity. Milk production on treatment B was also equal to that obtained in a previous experiment with a complete ration containing 7.5 percent less bagasse and 5.0 percent less molasses, and correspondingly higher proportions of soybean meal and shelled corn.

Continuous Feeding

Thirty dairy heifer calves were reared from birth to calving on rations containing 0, 6.8 or 13.7% rapeseed meal in substitution for soybean meal. The level of rapeseed meal did not significantly (P > 0.05) affect feed intake, weight gain or feed efficiency of heifers up to breeding weight (330–340 kg). The level of rapeseed meal did not significantly (P > 0.05) affect reproduction or milk production during the first lactation. However, there may have been a trend for lower conception rate and milk fat production during first lactation with the higher level of rapeseed meal.

The aim of this study was to evaluate influence of climatic conditions represented by daily air temperature and relative air humidity on indicators of Holstein cows’ milk quality and production. The first dataset represented individual milk production in day of milk performance recording (milk kg, fat %, protein %, and somatic cells count thous.*ml−1). The second dataset represented total daily milk characteristics of herd (milk kg, fat %, protein % and somatic cells count thous.*ml−1). A total of 654 Holstein cows were observed and evaluated. Both datasets were evaluated in relation to selected external influences (year, month, average daily air temperature, and average daily relatively air humidity). Statistical analysis was performed using SAS 9.3, and UNIVARIATE, REG and GLM procedure. Three groups of daily air temeperature (< 4.4 °C; 4.4 – 13.2 °C; > 13.2 °C), and daily relative air humidity (< 65.3 %; 65.3 – 80.4 %; > 80.4 %) were conducted for evaluation. Significant (P < 0.05) linear regressions were computed among daily air temperature and all milk production indicators, except of somatic cells count attribute. The highest individual daily milk production (35.94 kg, P < 0.01), and protein content (3.41 %, P < 0.01) were achieved with the highest average daily air temperature. Opposite results were observed for milk yield of herd as well as protein content. Average daily relative air humidity had lower influence on individual and bulk milk samples. The better results were achieved for both datasets (individual and bulk samples) in groups (65.3 – 80.4 %; > 80.4 %) of average daily relative air humidity. Obtained results point out importance of outdoor climatic parameters monitoring and preventive measures of climatic conditions in the stable.

Investigation of some production traits in two production years (2005, 2006) was carried out on East-Friesian sheep. Considerably (P<0.01) higher milk production (346 lit.) in 2005, in comparison to 2006 (250 lit.) was registered. The duration of lactation is considerably (P<0.01) greater in 2006 (264 days), compared to 2005 (232 days). The content of milk fat in the milk from this breed is in average 5.01%, i.e. 5.64%, for the two years consequently. The production of milk fat is 17.34 kg in 2005 and 14.11 kg in 2006. The percentage of proteins in our research, in average is 4.68% in 2005, i.e. 4.85% in 2006, while the production is 16.19, i.e. 12.12 kg. The number of obtained lambs per sheep is not considerably higher (P<0.05) in 2005 (1.64 lambs) in comparison to 2006 (1.48 lambs). Almost all the examined factors (year, lactation, number of milk control) highly influence (P<0.001) the daily milk production, with the exception of the year, which influences with a considerable importance (P<0.05) the evening milk. In regard to the milk fat, statistically highly significant (P<0,001) influence was established only of the number of sequence and the month of the milk control, while all the rest fixed factors (year, lactation, number of lambs) didn?t influence significantly (P>0,05) this component of milk. Except of the fats, all the examined factors influenced statistically highly significantly (P<0,001) proteins in the milk, with an exception of the number of lambs, which did not influence considerably (P>0,05) this component.

Kunak is the biggest community for a traditional dairy cattle farmer in West of Java. Providing good qualities and quantities of forage continuously in a year for ruminants, still be one problem in this community caused by different forage production between the dry season and rainy season. High forage production in the rainy season could be stored as silage to provide forage requirement in the dry season. These research examined in 2 experiments. The first experiment aimed to determine the effect partial-substitute of fresh forage uses grass silage on the quantities and qualities of daily milk production. The second experiment aimed to determine the quantities and qualities of dairy cattle milk production, affected by adding Gracilaria sp (GS) on partial-substitute of fresh forage uses grass silage and palm kernel-meal (S-PKM) on daily feed. These research uses complete randomized design divided into two treatments (to substitute as much as 0% and 10.08% Dry matter of fresh forage with grass silage) with five replications on the first experiment and three treatments (0%S-PKM-0%GS; 19.51%S-PKM-0%GS; 15.03%S-PKM-2.03%GS) with three replications on the second experiment. The results showed that substituting as much as 10.08% DM of fresh forage uses grass silage does not affect the feed intake (11.56-11.98 Kg DM/head/day), Feed Digestibility (59.37-63.45%), milk protein-production (0.36-0.37 Kg/head/day), milk fat-production (0.54-0.58 Kg/head/day), daily milk production (12.36-12.67 Kg/head/day) in the first experiment. Feed intake (Kg DM /head/day), milk protein-production (Kg/head/day), milk fat-production (Kg/head/day), and daily milk production (Kg/head/day) increase with added 15.03%S-PKM-2.03%GS in the second experiment.

The main goal of this study was to evaluate the health condition of dairy cows in relationship to milk production and milk composition using continuous monitoring boluses. In total, seven Holstein cows had boluses implemented for monitoring rumen pH and temperature every 15 min with an accuracy of ± 0.1 pH/ °C. Milk production test day records were noted by Breeding Services of Slovakia, s.e. (state-owned enterprise) 5 × per each cow with a bolus over 27 weeks of lactation. Dairy cows were divided into three groups according to their mean daily pH. After that, the test day records with the selected group were paired. Only two cows had pH values within the normal pH intervals during the control days. Consequently, there was found to be a 6.8% (P < 0.05) decrease in daily milk production in cows with lowered pH compared to cows with normal pH. Furthermore, there was found to be a 14.08% (P < 0.05) decrease in daily milk production in cows with an increased pH compared to cows with normal pH. Narrower fat to protein ratio and lactose content was found in cows with decreased and increased ruminal pH. The lowest milk fat concentration (P < 0.05) but the highest somatic cell count and urea content were determined in cows with decreased pH. These results show that continuous monitoring of rumen environment is a suitable method for nutrition and health management in dairy herds and allows the nutritionist to make nutritional interventions for pH stabilization within normal range in order to keep good milk production and high milk quality.
