Abstract A randomized block design experiment involving thirty beef cattle (mean initial live weight 462 kg) was carried out to evaluate a bacterial inoculant based on single strain of Lactobacillus plantarum as silage additive and provide further information in relation its mode action. Three herbages were harvested 10 August 1989 using three double‐chop forage harvesters from the first regrowth perennial ryegrass sward which had received 170 kg N, 25 P 2 O 5 , 42 K ha −1 . They either no...
Abstract A partially balanced change-over design experiment was made to examine the effects of concentrate energy source on voluntary food intake and animal performance 50 lactating dairy cows offered a diverse range grass silages. The silages were also as sole diet 10 in experiment. total five prepared. Silages A, B D C E harvested from primary regrowths secondary respectively predominantly perennial ryegrass swards. Herbage ensiled either pre-wilted or unwilted untreated treated with...
Abstract A changeover design experiment involving thirty‐six 3‐month‐old Friesian male calves (mean initial live weight 127 kg) was carried out to evaluate a bacterial inoculant based on single strain of Lactobacillus plantarum (Ecosyl, ICI) as silage additive. On 25–31 August 1988, nine silages were harvested using double‐chop forage harvesters from the second regrowth three swards, namely permanent pasture which had received 100 kg N ha −1 and perennial ryegrass either or 150 . Herbages DM...
A tremendous evolution has taken place in the field of equine reproduction during past decade.Advanced techniques, such as ovum pick up combined with intracytoplasmic sperm injection and embryo transfer, have become more routine procedures warmblood breeding.These techniques allow 'popular' mares to produce multiple foals per year via surrogate mares.The latter impression that only a limited number popular stallions are preferred by breeders due strong selection, could generate fast-paced...
The effects of maturity maize at harvest, level inclusion and potential interactions on the performance, carcass composition, meat quality concentrate-sparing effect when offered to finishing beef cattle were studied. Two silages ensiled that had dry matter (DM) concentrations 217 304 g/kg starch 55 258 DM, respectively. Grass silage was as sole forage supplemented with either 4 or 8 kg concentrate/steer daily in addition one two a ratio 0.5 : 0.5, DM basis, grass concentrate daily. also...
Abstract This experiment evaluated a bacterial inoculant based on single strain of Lactobacillus plantarum as silage additive. Three silages were harvested 8 September 1989 from the second regrowth perennial ryegrass sward, which had received 167 kg N, 28 P 2 O 5 and 45 K ha −1 . Mean dry matter (DM) water soluble carbohydrate concentrations herbages at ensiling 148 g 78 g.(kg DM) respectively. Herbages treated with either no additive (C), formic acid (3·0 1 t ) (F) or (I) ensiled in three...
The study involved 120 crossbred ewes (sixty 1.5 years old animals and sixty 2.5 animals; initial liveweight 67.6 kg, condition score 3.7), that were mated in October. They assigned to six treatments (two shearing (shorn unshorn) × two silage feed values (low medium) extended grazed herbage allowances (1.0 1.8 kg dry matter (DM)/day)) designed evaluate the effects of at housing, grass value extended-grazed allowance on their performance progeny. Swards, which had harvested 6 September,...
The effects of high and medium feed value grass silage or maize (MS), each offered with a range concentrate levels, ad libitum on the performance finishing lambs, which were either shorn unshorn, evaluated. Three silages used: 1 (MFV) (HFV) (DM digestibility [DMD] 71.3% 74.5%, respectively) MS starch concentrations 30.9% 35.3% DM, respectively). 3 daily allowances 0.4, 0.8, 1.2 kg per lamb. Two additional treatments were: 1) supplemented 0.4 low CP (LP) 2) 0.5 kg/d HFV silage. These 11...
Abstract The effects of energy source and level digestible undegraded protein (DUP) in concentrates on silage intake performance lactating dairy cows, offered one a range grass silages differing digestibility characteristics, were evaluated partially balanced change-over design experiment involving 48 cows. Four prepared using management practices prior to during ensiling. All treated with an inoculant additive. For A, В, С D, dry matter (DM) concentrations 199, 320, 313 223 (s.e. 4.6) g/kg,...
The prediction of silage feeding value from the analysis herbage at ensiling and effects rate nitrogen (N) fertilizer, date harvest treatment additive on fermentation, dry matter (DM) recovery effluent production were evaluated in a factorial experiment. Herbage was harvested 75 plots, laid out three replicate blocks 25, primary growth predominantly perennial ryegrass sward. plots received 72, 96, 120, 144 or 168 kg N/ha 10, 17, 24 31 May 7 June. ensiled for 176 days laboratory silos (6...
Abstract A randomized block experiment involving thirty‐six lactating dairy cattle was carried out to evaluate a bacterial inoculant (Grazyme Grobac, Agritech), containing bacteria, enzymes and rumen enhancer, as silage additive. Herbage from the primary regrowth of predominantly perennial ryegrass swards ensiled unwilted precision‐chopped after 51‐d growth interval on 4 5 August. Alternate loads herbage were either untreated (C) or treated with formic acid at rate 2.65 1 (t herbage) −1 (F)...
The effects of (i) medium and high feed value (MFV HFV) maize silages (ii) MFV HFV grass silages, each in combination with a range concentrate levels, on the performance finishing lambs were evaluated using 280 Suffolk-X (initial live weight 36.1 kg). represented crops dry matter (DM) concentrations 185 250 g/kg, respectively, at harvest, had starch metabolisable energy (ME) 33 277 g/kg DM 9.6 11.0 MJ/kg, respectively.
