“…In recent Finnish experimental data sets for dairy bulls fed grass silage and grain based diets and housed in similar environments (Huuskonen et al 2016(Huuskonen et al , 2017a(Huuskonen et al , 2017b, the average DM intake of the bulls was roughly at the same level as in the present experiment. In an earlier meta-analysis Huuskonen et al (2013) found that DM intake of growing and finishing cattle can be predicted from body weight and diet composition with a reasonable accuracy.…”

The objective was to study the effects of partial replacement of barley grain by rye grain on dry matter (DM) intake and growth performance of growing bulls. The experiment was conducted using 80 dairy bulls which were fed total mixed rations ad libitum. The rations included grass silage (500 g kg-1 DM) and concentrate (500 g kg-1 DM). Four different experimental concentrate mixtures included rye at 0, 150, 300 and 450 g kg-1 DM. The average daily DM and metabolisable energy intakes of the bulls were 10.9 kg d-1 and 127 MJ d-1, respectively. There were no differences in DM, energy or nutrient intakes among the treatments. The average live weight gain and carcass gain of the bulls were 1543 and 832 g d-1, respectively, and rye inclusion had no effects on growth. There were no significant differences in feed conversion or carcass characteristics among the treatments. It can be concluded that rye grain is a suitable energy supplement with good quality silage for growing dairy bulls.

“…The bulls were fed a total mixed ration ad libitum (proportionate refusals of 5%). Mineral and vitamin composition of the mineral-vitamin mixture (Kasvuape E-Hiven, A-Rehu Ltd., Seinäjoki, Finland) is fully described by Huuskonen et al (2017). Two HO bulls (one SALT and one ACID) were excluded from the study due to pneumonia and one HO bull (SALT) due to several occurrences of bloat.…”

SUMMARYThe effects of silage additives on performance of dairy bulls were determined in a feeding trial using 45 Nordic Red and 45 Holstein bulls. Both breeds were allotted randomly to three treatments: (1) timothy silage (TS) without additives + barley (CON); (2) TS with sodium benzoate, potassium sorbate and sodium nitrate-based additive + barley (SALT); and (3) TS with a mixture of mostly formic acid and propionic acid-based additive + barley (ACID). The bulls were fed total mixed rations ad libitum. During the experimental period of 259 days, the average dry matter intake was 10·1 kg/d and there was no difference among the treatments. The average live-weight gain (LWG) and carcass gain was 1363 and 741 g/d, respectively. There were no treatment differences in the carcass gain but LWG of the CON bulls was 5% higher compared with the SALT and ACID bulls. Carcass conformation score of the SALT and ACID bulls was 6% higher compared with the CON bulls. The experiment demonstrated that there was only a slight benefit from silage additives in animal performance when silage dry matter was 350–400 g/kg and silage was ensiled in round bales.

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first-and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second-or third-cut grass silage (550 g kg -1 dry matter), rolled barley (435 g kg -1 dry matter) and a mineral-vitamin mixture (15 g kg -1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first-or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first-and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.
