Lactating Dairy Cows

Vacuum silages made from Pioneer 383 and Pride 5 corn were fed with concentrate and with and without hay to lactating dairy cows. Yields per hectare in terms of dry matter were 8,850 kg for Pioneer 383 and 8,350 kg for Pride 5. Intake of silage dry matter was significantly higher (P < 0.05) for Pride 5 (11.4 kg/day) than for Pioneer 383 (9.8 kg/day), and significantly lower (P < 0.05) for both silages when hay was fed (11.4 kg/day versus 9.7 kg/day). Fat-corrected milk production was significantly higher (P < 0.05) for Pride 5 (17.0 kg/day) than for Pioneer 383 silage (15.8 kg/day), and significantly higher (P < 0.05) when hay was fed, than without hay supplementation (167 kg/day versus 16.0 kg/day). Utilization of silage dry matter in terms of fat-corrected milk production per hectare was 10,486 kg for Pride 5 corn silage and 11,176 kg for Pioneer 383 corn silage.

Ramirez-Ramirez, H. A., Geis, A. R., Heine, C. S., Clark, K. J., Gehman, A. M. and Kononoff, P. J. 2011. Storage conditions of wet corn distillers’ grains with solubles in combination with other feeds and understanding the effects on performance of lactating dairy cows. Can. J. Anim. Sci. 91: 331–339. Wet distillers’ grains are commonly stored in polyethylene silo bags until needed for feeding. The objective of the first experiment was to evaluate the nature of ensiling wet distillers’ grains with soluble (WDGS) alone or in combination with other feeds. A 3×4×3 factorial experiment was conducted in which 36 mixtures were made using three loads of distillers’ grains stored at varying levels with three feeds (corn silage, ground corn, and brome hay). In all mixtures, the addition of feeds to WDGS increased the pH of stored material. The objective of the second experiment was to evaluate the effects of feeding WDGS on milk production. Twenty Holstein cows were used in a 4×5 Youden square. Prior to initiation of the study, WDGS were stored alone (WDGS) or mixed with either 12% ground corn (DM basis) (WDGS+C), 15% brome hay (DM basis) (WDGS+H) or 15% corn silage (DM basis) (WDGS+CS) in polyethylene silo bags. Animals were assigned to one of five treatments during each 21-d period. A diet not containing WDGS was formulated (Control), along with one containing 30% WDGS (DM basis) (WDGS). Three additional diets, similar to the WDGS treatment, were formulated to include one of the three blends of WDGS with corn (WDGS+C), brome hay (WDGS+H) or corn silage (WDGS+CS). Dry matter intake (DMI) was affected by diet and, compared with Control (21.9 kg d−1±0.70 kg d−1), was greater for WDGS (23.8±0.70 kg d−1) and WDGS+C (23.7±0.70 kg d−1). Milk yield, 3.5% FCM, and fat yield were not affected by treatment. These results suggest that dairy rations can be formulated to include stored WDGS at 30% DM without negative effects on milk production and composition.

Dough Stage

Whole crops of corn, barley, wheat, and forage oats were ensiled and fed as the sole forage to 48 milking cows in two 12-wk feeding trials. In the first experiment corn (25.1% dry matter (DM)) harvested in the early dent stage, barley (34.2% DM), and forage oats (27.6% DM) harvested in the dough stage were compared. Holstein cows fed the three silages averaged 22.6, 19.7, and 18.7 kg of 4% fat-corrected milk per day and consumed 1.67, 1.82, and 1.85 kg of silage DM per 100 kg body weight, respectively. In the second experiment, cows fed wheat (35.7% DM), barley (29.8% DM), or forage oat (27.0% DM) silage harvested in the dough stage produced 21.2, 23.3, and 22.1 kg fat-corrected milk daily and consumed 1.75, 1.71, and 1.62 kg silage DM per 100 kg body weight, respectively. Corn silage DM intake was lower (P < 0.01) but more efficiently utilized for milk production (P < 0.01) than barley or forage oats, whereas wheat, barley, and forage oat silages were similar in feeding value. In experiment I, rumen acetate increased and butyrate decreased with corresponding increases in forage fiber content. Propionate levels were unaffected by the kind of forage, whereas blood urea nitrogen was highest for cows fed forage oats in both experiments.

Effect Of Feeding

The study was conducted to evaluate the effect of feeding herbal galactogogue preparation (Sanjivani biokseera) on the milk yield and milk constituents in lactating Kankrej cows. Thirty-two lactating Kankrej cows in their 1st to 6th lactation were taken for the experiment from 3 days after calving up to 52 days postpartum. All the animals were fed as per the standard seasonally available roughages and concentrates to meet their nutritional requirements. The cows were randomly divided into two uniform groups of 16 cows in each according to initial milk yield and milk composition. The animals in group-I were not given any supplement and served as control. The animals in group-II were given Sanjivani biokseera (Naturewell Industries) @ 60 g per day for 1-month, commencing 3 days after calving, in addition to the usual feeds/fodders. A clear difference was observed in milk yield from day 8 onward of experiment between groups with significant (plessthan0 0.05) higher values from day 16-52 in cows fed herbal galactogogue as compared to control, but no such distinct effect on milk constituents was observed on day 52 when analyzed. The use of herbal galactogogue significantly (p lessthan 0.05) increased the overall average of 52 days milk production, which was 9.34 ± 0.21 lit/day in supplemented as compared to 7.75 ± 0.26 lit/day in control animals. It was concluded that herbal galactogogue (Sanjivani biokseera) could increase milk yield in lactating dairy cows through its galactopoetic property and improved rumen environment.
