“…Unfortunately, the differences among treatments in our trial were not statistically proved. In numerous studies carried out on cows from weeks 3, 4 or 6 before calving until weeks 4 or 8 of lactation it was found that feeding rations enriched in energy and protein resulted in higher milk production but similarly as in our experiment the differences, although in many cases quite high, were not always statistically signifi cant (Olsson et al, 1998;Vandehaar et al, 1999;Ballard et al, 2001;McNamara et al, 2003). In such experiments the management conditions as well as physiological stage should be clearly defi ned (Ballard et al, 2001).…”

“…They are based more on practical approaches than on real requirements established in metabolic experiments, which are still lacking. However, feeding cows diets containing more concentrates than recommended by standards for this period, reduced post-partum NEB and increased milk yield, although the effects of concentrate addition over recommended standards were not always statistically signifi cant (Olsson et al, 1998;Vandehaar et al, 1999;Ballard et al, 2001;Jurkiewicz et al, 2005;Osięgłowski and Strzetelski, 2006).…”

A two-factorial experiment was carried out on Polish Holstein-Friesian cows from the 6 th week before parturition to the 12 th week of lactation, allotted into 6 groups of 8 animals that before parturition and in the fi rst week of lactation were fed rations differentiated in protein and energy levels. Animals of each group received two kinds of concentrate (1.10-1.12 UFL/kg DM) containing barley (subgroup B) or maize (subgroup M) as the main source of energy. Cows from group I (control) were fed according to IZ-INRA (2001) standards before parturition and in early lactation. The level of concentrate in diets for every group was increased weekly either from week 3 before parturition to the fi rst week of lactation (kg/day in week 3, 2, 1 before parturition and week 1 after parturition, respectively): in group I -1, 2, 2, 4; group II -1, 2, 4, 6; group III -2, 2, 2, 4; group IV -2, 2, 4, 6 or from week 6 before parturition to the fi rst week of lactation (kg/day in week 6, 5, 4 3, 2, 1 before parturition and week 1 after parturition, respectively): group V -2, 2, 2, 2, 2, 2, 4 and group VI -2, 2, 2, 2, 2, 4, 6.Irrespective of starch source, cows of groups II, IV and VI receiving 2 kg of concentrates more than others, both in week 1 before parturition and in the fi rst week of lactation, consumed more Journal of Animal and Feed Sciences, 17, 2008, 473-490 5 Corresponding author: e-mail: jstrzet@izoo.krakow.pl 474 DIETARY CONCENTRATE LEVEL FOR TRANSITION COWS dry matter (P<0.01), which may suggest reduction of energy and protein defi cits. Differences in the concentration of metabolites in blood serum did not differ signifi cantly between the groups, but numerically higher values of non-esterifi ed fatty acids, β-hydroxybutyric acid, glucose, insulin and aspartate aminotransferase in group VI, both before and after parturition, may suggest a benefi cial infl uence of concentrate allocation method on energy balance. Milk yield did not differ among groups, although cows of group VI produced from 1.05 to 2.47 kg/day more than cows of other groups. The concentrate allocation method signifi cantly affected (P<0.01) milk protein content, with the highest values for groups V and VI. On the other hand, the source of starch, irrespective of concentrate allocation method, did not infl uence dry matter intake or level of metabolites in blood serum. Cows fed rations containing barley produced 0.94 kg/day more milk than those fed concentrate with maize, but the differences were not statistically signifi cant (P>0.05). The concentration allocation and starch source did not infl uence reproduction performance.The results of this study suggest that concentrate allocation, in particular, increasing the amount of concentrate provided in the last week of pregnancy and fi rst week of lactation, may affect production and energy metabolism of transition cows. Extension of concentrate feeding to 6 weeks before parturition may additionally improve energy balance. The source of starch plays no important role.

“…Propylene glycol and/or Ca-propionate, employed as glucogenic additives in the studies carried out by Ballard et al (2001), DeFrain et al (2005) or Moallem et al (2007) did not have any significant influence on fat content in milk.

“…Even so, its low palatability can be masked by thoroughly mixing with other feed components (Nielsen et al, 2004). In many studies, neither negative impact of PG (Miyoshi et al, 2001;Moallem et al, 2007), nor propionate (DeFrain et al, 2005) or both of them (Ballard et al, 2001) on feed intake was noted.

“…The energy imbalance can lead to the occurrence of metabolic disorders related to nutrition and feed management problems, like ketosis (Ballard et al, 2001;Patton et al, 2004;Moallem et al, 2007). Preventive measures against this disease and its negative influence upon milk production involves dietary inclusion of various glucogenic preparations (Nielsen and Ingvertsen, 2004;Klebaniuk Supported by the Polish State Committee for Scientific Research (Grant No.…”

A two-factorial experiment was carried out on 6 groups (10 animals each) of Polish Black and White Holstein-Friesian cows in the transition period to determine the effect of glucogenic additive (GA) to the diets containing grains of varied ruminal starch degradation on cow performance. The animals from 3 control groups (C-groups) were fed the diets without any additive, whereas 3 other, experimental ones (A-groups) received the diets with additive of glucogenic preparation (450 g per head/day) comprising calcium propionate and loose propylene glycol (1 : 1). In the control groups as well as in the experimental ones, three analogical treatments, differing in concentrate composed of grain species of varying ruminal degradability of starch, i.e. maize (M) -low ruminal degradability, barley and wheat (BW) -high ruminal degradability and marriage of them (MBW) were conducted. Finally, the treatments were: C-M, C-BW, C-MBW, A-M, A-BW, and A-MBW. The rations of all groups based on maize silage, haylage, and meadow hay were mixed at 69 : 19 : 12 ratio (dry matter (DM) basis) and given ad libitum. Besides, all the animals received adequate concentrate rations to satisfy their nutritional requirements. The experiment started two weeks before the expected parturition and lasted till the 6 th lactation week. Neither GA nor a type of grain in the diets showed significant negative influence on DM intake. A glucogenic additive has positively affected some basal nutrient digestibility, elevating significantly DM and crude protein (CP) coefficients of the apparent total tract digestibility (CATTD), by about 3 percentage points. The GA × grain interactions (P ≤ 0.05) in CATTD of CP and nitrogen-free extract (NFE) were stated, with the peak values reported in the A-BW treatment. GA increased (P ≤ 0.05) daily milk yield by nearly 5% in comparison with the control treatments. GA × grain interaction was noted with the best effect in the treatment where GA was given along with maize-barley-wheat-based concentrate. Besides, the glucogenic additive decreased (P ≤ 0.05) protein (PDI) expenditure per 1 kg of fat-corrected milk (FCM) by ca. 6% and raised (by 0.15 percentage point in week 6) protein content, while lowered the urea milk level in weeks 3 and 6 of lactation by approximately 15%. It showed beneficial effect on cow reproductive indicators reducing the time interval from calving to successful insemination and improving insemination index.
