Compared with most grass silages, maize silage has a low ratio of rumen degradable protein: fermentable energy. Unlike grass silage, maize silage contains rumen fermentable starch. These differences imply that a different regimen of supplemental nutrients is required to optimise cow performance on rations containing maize silage compared with rations based on grass silage. The objective of this study was to define responses of dairy cows fed rations based on maize silage to supplements of rumen fermentable starch (RFS) and effective rumen degradable protein (ERDP).

In 3 feeding trials high-yielding cows and heifers (102, 72 and 92, respectively) were given diets from week 2 of lactation containing grass silage and maize silage and concentrates with slowly or rapidly degradable protein (DP). Diets were given according to the standard or slightly above the standard for digestible crude protein and net energy for milk production. A sample of peripheral blood was taken immediately before the morning feed and at 3-4.5 h after the concentrate was given. Blood urea was higher and blood glucogenic amino acids were lower (P

Degradable Protein

In two feeding trials involving 96 rearing calves each and based on a 2 x 3 factorial design, a comparison was made between concentrates containing rapidly and slowly rumen-degradable protein and among concentrates with lysine 6, 7 and 8 g/kg or 7, 8 and 9 g/kg. In a third trial involving 84 animals, 2 feeds containing rapidly and slowly degradable protein were compared. Calves were weaned at 6 weeks and remained in the trial an additional 5 to 6 weeks. Concentrates were fed freely from 21 days old and in 2 trials after weaning the calves were fed according to a plan based on body weight. Hay or prewilted grass silage was given freely. Difference in protein degradability between feeds with rapidly degradable protein and those with slowly degradable protein was 28 and 36% in the second and third trials. Treatments involving concentrates with slowly degradable protein resulted in a higher daily weight gain. Feed efficiency was usually improved. Increase in lysine content of the concentrate from 6 to 8 g/kg or from 7 to 9 g/kg resulted in a significant linear rise in daily weight gain and a linear rise in feed efficiency. In 2 of the 3 trials intake of roughage (1 x prewilted grass silage, 1 x hay) was positively affected by presence in the concentrate of slowly degradable protein. Lysine content of the concentrate had no effect on roughage intake. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Profitability of dairy farming in relation to the type of feeding systemWe investigated the profitability of dairy farms in relation to the type of feeding system (seasonal pasture vs. permanent housing). An economic analysis was carried out of data on the structure and financial health of 50 farms in 2007 using questionnaires filled in by the farmers. The Principal Component Analysis (PCA) was applied to reveal causal relationships between a number of characteristics of the farms. The two axis of PCA explained 40.48% and 16.13% of the variability among the selected farm characteristics. Profitability related more to the number of subsidies, the area of arable land, the number of livestock and to the milk and plant production than to the area of meadows and pastures. Although a better cow performance was achieved on farms with confined herds, the profit per agricultural area and profit rate did not differ significantly between the two feeding strategies (P>0.05). The profit was 3,259 and 3,655 CZK/ha on average and the profit rate 7.9% and 5.6% on average on farms with pastured herds and on farms with confined herds, respectively. A lowering of input costs and a more effective utilisation of grasslands may further enhance profitability.

Abstract One hundred four Angus calves were ranked by gender, BW, age, and dam parity, and assigned to 1 of 4 pre-weaning treatments: 1) nose flaps for 7-d prior to weaning (NF), 2) traditional weaning (TRAD), 3) traditional weaning and creep feed for 3-wk prior to weaning (TRADC), or 4) nose flaps for 7-d prior to weaning and creep feed for 3-wk prior to weaning (NFC). Cow-calf pairs were housed in dry lot pens on d -28. From d -21 to 0, calves in creep treatments were provided free choice access to creep feed. Nose flaps were placed on d -7, and calves were weaned on d 0. Calves were vaccinated and dewormed on d -21 and 0. There was no difference (P ≥ 0.97) in calf BW on d -28 or -21. During the 7-d period that nose flaps were placed, NFC calves had greater (P ≤ 0.0001) ADG than NF and TRAD calves, and tended to have greater (P ≤ 0.10) ADG than TRADC calves. At weaning on d 0, TRADC and NFC calves tended to have greater BW (P = 0.07) and had greater overall change in BW (P < 0.0001) during the pre-weaning period than TRAD and NF calves. Additionally, there was a greater (P ≤ 0.001) increase in BW of NFC and TRADC cows during the pre-weaning period compared to NF and TRAD cows. From d -21 to 0 there was no differences (P > 0.41) in plasma concentrations for Bovine Viral Diarrhea Virus (BVD). By d 14, the TRADC calves had the greatest plasma concentrations for BVD (P < 0.04). Therefore, providing short-term creep feed prior to placing nose flaps can improve pre-weaning calf and cow performance compared to traditional and nose flap weaning without creep feed supplementation, however, did not improve response to vaccination.
