A comparison of individual cow versus group concentrate allocation strategies on dry matter intake, milk production, tissue changes, and fertility of Holstein-Friesian cows offered a grass silage diet

SummaryIn two trials the effect on D.M. intake of applying flavouring agents to grass silage at feeding time was examined using a total of 89 British Friesian cows in mid to late lactation. The flavouring agent used in Expt 1 was Simax 100 (5 ml/cow per day), while in Expt 2 Palatol (20 ml/cow per day), molasses (0·7 kg D.M./cow per day) and molasses + Talin (0·7 kg D.M./cow per day) were added to both lowand high-quality grass silage.Both Simax (significantly) and Palatol increased silage D.M. intake by an average 0·67 kg/day. The total D.M. intake of the cows fed the molasses and molasses + Talin was similar to that obtained by those receiving the silage treated with Simax and Palatol. However, in the case of the cows receiving the molasses and molasses + Talin, the increased D.M. intake was obtained mainly from the additional molasses and not by an increased silage intake. This result indicates a very low substitution rate for molasses.Although D.M. intake was increased by the addition of flavouring agents, milk production remained unaltered because of the relatively late stage of lactation of the cows in both trials.

Whole crop wheat (WCW) appears to offer an attractive alternative forage to grass silage for dairy cows, particularly in those areas where maize silage cannot be grown. However in previous feeding trials the inclusion of WCW with grass silage has increased food intake but has not led to a corresponding increase in milk yield (Phipps et al,1993). As part of a programme to try to overcome the low efficiency of diets containing WCW, the present experiment was designed to examine the effects on feed intake and digestibility and milk production of the step-wise replacement of GS by urea-treated WCW.Winter wheat (cv Hussar), harvested at 620g DM/kg fresh weight and preserved with 20 or 40 g urea/kg DM (WCW-2, WCW-4) was compared with first-cut perennial ryegrass silage (GS). Six multiparous Holstein-Friesian cows in mid-lactation were offered six diets over three 4-week periods in an incomplete change-over design. Diets were 6kg DM concentrates daily with forages ad lib. Treatments (DM basis) were GS alone, 2:1 GS:WCW-2 or WCW-4, 1:2 GS: WCW-2 or WCW-4, and WCW-4 alone. Feed intake and milk production were measured in weeks 3 and 4 and digestibility in week 4.

Complete Diet

In a previous study at this Institute, significant increases in total dry matter intake were obtained with first lactation animals offered grass silage and concentrates as a complete diet rather than in separate feeds. However, the increased DM intake associated with complete diet feeding was not reflected in improved animal performance. Similar results have also been reported by Phipps, Bines, Fulford and Weller (1984) and Cassel, Merrill, Milligan and Guest (1984).The aim of this experiment was to investigate the effect on animal performance of offering two types of concentrate in addition to grass silage, with concentrates offered either as a complete diet or in three feeds per day.

Milk production and composition was determined in Holstein-Friesian cows fed either 3.5 or 7.0 kg dry matter (DM) daily of lupin grain, pea grain, faba bean grain or barley grain with or without 1.5% added urea, as supplements to an oaten hay based diet. All the grains were hammermilled. Daily yields of milk (L), fat (kg) and protein (kg) were significantly (P<0.05) higher for cows fed lupin (20.0, 0.81, 0.57), pea (18.9, 0.80, 0.56) and faba bean (18.9, 0.79,0.55) grains compared with those of cows fed barley grain with (17.8, 0.73, 0.51) or without (18.0, 0.71, 0.52) urea. Yields of milk (L), fat (kg) and protein (kg) and milk protein content (g/kg) were significantly (P<0.05) higher when 7.0 kg DM (19.5, 0.80, 0.57, 29.6) compared with 3.5 kg DM (18.0,0.73,0.51,29.0) of grain was fed. There were no significant differences between treatments in hay DM intake by cows fed 3.5 kg DM of grain daily. A significantly (P<0.05) higher milk fat production per unit DM intake was recorded for cows fed legume compared with barley grain. There were generally higher returns above grain cost for cows fed legume compared with barley grain and for cows fed 4 kg compared to 8 kg daily of grain. It was concluded that it was more economical to feed 3.5 kg DM of legume grain compared with 3.5 kg DM of barley grain, with or without urea, as supplements for cows offered cereal hay in early lactation. However, the economics of feeding 7.0 kg DM of legume grain compared with 7.0 kg DM of barley grain and 7.0 kg DM compared with 3.5 kg DM of grain will depend on the costs of relative changes in hay intake associated with these practices.

In a previous experiment outlined at last year's conference (Hyslop and Roberts, 1988), it was demonstrated that replacement of a proprietary pelleted concentrate with malt distillers grains (draff), should be limited to 15% of total dry matter intake (DMI) when draff is offered in two feeds per day. However there is little evidence to validate such a limitation when draff is used as a concentrate replacement in complete diets. This experiment examined the effect of replacing barley/soya with draff plus additional minerals in silage based complete diets.In a cyclic changeover design experiment consisting of 4 three week periods, fifteen British Friesian cows in early lactation were offered five treatments. Cows were given ad libitum access to one of five complete diets based on grass silage (69 “D”). Draff plus additional minerals gradually replaced barley/soya at increasing rates in diets 0-4 respectively.

The importance of measuring partition between body and milk in dairy cows and identifying the factors underlying it has long been recognised. However accurate measurements of partition In the body are few because of the difficulty and expense of the techniques.The purpose of the present experiment was to measure the effects in autumn-calving Holstein-Friesian cows given grass silage ad libitum of amount of concentrate and stage of lactation on body composition by direct (Gibb et al 1992a, b) and Indirect (Kings et al 1992) techniques, adipose tissue metabolism (Walsh et al 1992) and milk production. In a related trial, energy balance was measured in other cows by Indirect calorimetry (Cammell et al 1992).This report covers silage Intake, milk production and live-weight change. Communications on the associated studies are given in the Proceedings of this Meeting.

An understanding of the dry matter intake (DMI) capacity of suckler cows is crucial to the provision of adequate nutrition during lactation. However, quantitative data on the likely feed intake patterns of modern continental x dairy suckler cow genotypes is scarce. The objective of the current experiment was to determine voluntary DMI in Simmental x Holstein/Friesian (SIM) and Belgian Blue x Holstein/Friesian (BB) autumn calving suckler cows offered a grass silage based diet ad libitum.

Friesian Cows

In our study the behavior of dairy cows was studied during the first three months of lactation. The experiments were done on 25 cows raised in free-stalls on slatted floor in 25.5-31.5 m 2 boxes. In the experimental period the cows were fed grass, silage and hay. The concentrates were used for feeding during the milking time and the quantity depended on milk production of each cow. The dairy cows were monitored every 10 minutes in 24 hours period for several days. We have observed that the primiparous and secundiparous cows are resting 1-2 hours less than the older cows. The time needed to ingest the forages is longer at primiparous and secundiparous. During 24 hours, cows are spending 12-14 hours on rest, so it is necessary to build comfortable and spacious pens. Cows are spending 5-6 hours on feeding, so we must provide a larger feeding area for each cow.
