Ad Libitum Feeding of Either a Complete Ration Based on Sugarcane Bagasse or a Conventional Concentrates Mixture to Dairy Cows

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.

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.

The objective of this study was to determine the effect of spineless cactus incorporation in food of dairy goats and growing kids on milk production and composition and on kid's growth and meat characteristics. Two experiments were conducted on Tunisian local goats. In the first, 30 females were divided into two groups; goats of Control group were reared on grazing pasture receiving indoor 0.5 kg of hay and 0.4 kg of concentrate. Goats for the second group (Cac-FL) were kept in feedlot and fed cactus ad libitum more 0.5 kg of hay and 0.4 kg of concentrate. In the second experiment, 14 kids were divided into 2 groups receiving 600 g of hay. The Control group received ad libitum a concentrate containing 130 g crude protein (CP) per kg of dry matter. The second group received cactus ad-libitum plus the half concentrate quantity of control one with 260 g CP/kg DM (Cactus). The daily milk production averaged 485 ml for Control group and 407 ml for Cac-FL one. The milk fat content was significantly higher for Control than Cac-FL group. In the second experiment, animals in Control and Cactus groups had similar growth rate. Carcass fat was significantly lower in Cactus than in the Control group. Cactus in the diet was associated with more C18:2 and conjugated linoleic acid as well as a higher proportion of PUFA than Control ones.

The reduction in milk production following a decrease in feeding level was compared with the increase in milk following an increase in feeding level of cows. Forty cows in their 5th month of lactation were allocated to 2 groups and offered either ad libitum pasture or restricted in their grazing so that, after 32 days, the difference in daily milk yield between the groups averaged 3 L/cow. Cows in each group were then offered cut pasture in stalls for 4 weeks to obtain mean daily intakes of either 14.4 or 10.2 kg DM/ cow The reduction in yield of milk energy (0.133 MJ/MJ metabolisable energy intake) following the decrease of intake from 14.4 to 10.2 kg DM/cow.day was similar to the increase in yield of milk energy (0.140 MJ/MJ metabolisable energy intake) following an increase in intake from 10.2 to 14.4 kg DM/cow.day. We conclude that, for cows in mid-lactation, the decrease in milk production following a decrease in feeding level is similar to the increase in milk production following an increase in feeding level. This implies that increases in milk production due to increased feeding can be predicted from experiments which measured reductions in milk production.

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.

The Difference

The objective of this study was to estimate the effect of the thyroglobulin (TG) locus on beef quality traits in some beef cattle breeds and to investigate the effect of the DGAT1 locus on milk production traits in the Hungarian Holstein Friesian population. TG and DGAT1 genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. At the TG locus TT bulls showed the highest fat percentage values in the longissimus dorsi muscle (m. longissimus dorsi); the difference between CC and TT genotypes was significant. DGAT1 GC/GC cows had the highest milk, fat and protein yield values. Due to the relatively small number of GC/GC cows the difference proved to be significant only between AA/AA and AA/GC genotypes.

The purpose of this research was to determine and to assess the milk production of Holstein Friesian cows in Capita Farm based on its lactation period. The research was conducted on 29thSeptember – 28thOctober 2019. The materials used in the study were 59 FH dairy cows in the lactation period of 1-6 and lactation months of 1-10. The body weight was 497.71 ± 44.73 kg and the milk production was 14.43 ± 4.43 liters / day / head. The study was conducted by observation. The parameters observed were the lactation period and daily milk production. Afterward, the daily milk production was converted into milk production in one lactation period. The difference in milk production of one lactation period between the lactation periods was determined by the independent sample t test at level of 5%. The results of this research showed that the peak production in the 4th lactation period was 4458.26 liter/lactation, while the 1st, 2nd, 3th, 5th, 6th lactation periods were 3976.85; 4100.01; 4143.85; 3850.27; 2938.56 liter/lactation, respectively. The 6th lactation period was significantly lower than the others withproduction capability of 65.91% of the mature equivalent (ME). It was concluded that the Holstein Friesian dairy cows inCapita Farm has the highest production in the 4th lactation period, but there is a real difference in production when it enters the 6thperiod.

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.

ABSTRACTObjective. The objective of the current study was to compare two methods to estimate daily milk production in crossbred hair ewes. Materials and methods. Eight multiparous, crossbred (Pelibuey x Katahdin) lactating hair ewes were used in a completely randomized design with repeated measurements, for 56 days. Ewes were fed ad libitum with a diet based on concentrate. Milk production was estimated twice a week for each ewe by both methods, suckled-hand (SH) and weigh-suckle-weigh (WSW) method. Results. Milk production (p>0.05) means were 1031.9±95.6 and 1119.0±95.6 g/day/ewe for SH and WSW method, respectively. Conclusions. No significant differences (p>0.05) were found between methods for milk yield.RESUMENObjetivo.
