metabolic parameters and their relationship to energy balance in multiparous simmental brown swiss and holstein cows in the periparturient period as influenced by energy supply pre and post calving
Journal of Animal Physiology and Animal Nutrition, 2015Co-Authors: M Urdl, L Gruber, W Obritzhauser, A SchauerAbstract:A study was conducted to evaluate the effects of three energy supply (E) levels [low (L), medium (M), high (H)], both pre-partum (PRE) and post-partum (POST), and their interactions on metabolic parameters and energy balance (EB) in dairy cows of three breeds. In both phases, E levels applied to a total of 81 multiparous cows of breeds Simmental (SI), Brown Swiss (BS) and Holstein-Friesian (HF; n = 27 for each breed) were 75%, 100% and 125% of recommendations of the German Society of Nutrition Physiology, using a 3 × 3 factorial arrangement of treatments. During the pre-calving period, serum concentrations of non-esterified fatty acids (NEFA) were higher for L(PRE) cows, and glucose concentrations were elevated for H(PRE) cows. During the lactation period, NEFA concentrations were greatest for treatment L(POST). Mean concentrations of β-hydroxybutyrate (BHB) were highest for cows of the L(POST) treatment, intermediate for M(POST) and lowest for H(POST). Glucose concentrations were lower for L(POST) cows. SI cows had lower BHB concentrations both pre- and post-calving and higher glucose concentrations during early lactation than the other breeds. BHB concentration POST was highest for BS cows. Restricted feeding PRE resulted in a better energy status of cows fed above energy requirements POST (E(PRE) × E(POST) interaction). HF cows had a higher EB pre-calving, whereas SI cows had a less negative EB during early lactation, compared with the other breeds respectively. Correlations of serum NEFA, BHB and glucose concentrations with EB were strongest during the transition period. Results suggest that controlling energy intake during the dry period might be advantageous for the energy status of dairy cows after calving, whereas energy restriction in early lactation leads to metabolic stress. Evidence is provided of a clear relationship between EB and the blood metabolites NEFA and BHB, especially in the transition period.

influence of energy and nutrient supply pre and post partum on performance of multiparous simmental brown swiss and holstein cows in early lactation
Animal, 2014Co-Authors: L Gruber, M Urdl, W Obritzhauser, A Schauer, J Hausler, B SteinerAbstract:A study was conducted to evaluate the effects of pre partum (PRE) and post partum (POST) dietary energy and nutrient supply (E) and their interactions on feed intake, performance and energy status in dairy cows of three breeds. In this experiment, the effects of three energy and nutrient supply levels (low (L), medium (M), high (H)), both pre-calving and post-calving, were investigated, using a 3×3 factorial arrangement of treatments. In both phases (84 days pre- and 105 days post-calving) E levels applied to a total of 81 multiparous cows of breeds Simmental (SI), Brown Swiss (BS) and Holstein–Friesian (HF; n =27 for each breed), were 75%, 100% and 125% of recommendations of the German Society of Nutrition Physiology (GfE). Dry matter intake (DMI) was restricted, if energy intake exceeded target values. Pre partum DMI and energy intake were different as designed, liveweight and body condition score (BCS) of SI cows were higher, but EB was lower, compared to BS and HF cows. Milk yield and composition were influenced by all three main experimental factors (E PRE , E POST , breed). Energy-corrected milk yield was 25.6, 28.6 and 30.1 kg/day for L PRE , M PRE and H PRE as well as 21.5, 30.1 and 32.6 kg/day for L POST , M POST and H POST , respectively. Numerically, only for milk protein content the interactions E PRE ×E POST and E PRE ×breed reached significance. Impact of energy supply pre-calving was more pronounced when cows had lower energy supply post-calving and vice versa . On the other hand, milk yield response of cows to energy supply above requirements was greater for cows that were fed on a low energy level pre partum . Impact of energy level pre partum was higher for HF cows, showing that their milk production relies to a greater extent on mobilization of body reserves. Increasing energy supply pre partum led to a more negative energy balance post partum , mainly by increasing milk yield and content, whereas feed intake was slightly reduced. Increasing energy supply post partum enhanced milk yield as well as milk protein and lactose content. Calculated energy balance corresponded well with liveweight and BCS change. Response of milk yield to increasing energy supply followed the principle of diminishing returns, since energy was increasingly partitioned to body retention. Increasing energy supply pre partum enhances milk yield and content post partum , but exacerbates negative energy balance and its consequences.
