The objective of this study was to evaluate the production, consumption, and energy balance parameters of primiparous 3/4 and 7/8 Holstein × Gir (HG) dairy cows fed two diets of differing energy levels during the postpartum period. At the beginning of the study, 28 days prepartum, the average weight of both genetic groups was 498 ± 12 kg and body condition score (BCS) was 3.5 ± 0.05. At the end of the study, 61 days postpartum, the 3/4 HG cows had higher weight and body condition scores than the 7/8 HG (456 ± 8 and 429 ± 8 kg and 3.13 ± 0.03 and 2.94 ± 0.03 BCS for 3/4 HG and 7/8 HG, respectively). Milk from cows fed the highenergy diet had higher percentages of fat, protein, lactose, and total dry extract than cows fed the low-energy diet. Cows fed the high-energy diet had higher net energy intake (95.3 ± 1.9 vs. 88.1 ± 2.1 MJ/day) and higher energy balance (3.64 ± 2.13 vs − 6.02 ± 2.30 MJ/day). The 3/4 HG cows displayed higher energy for maintenance (33.1 ± 0.4 MJ/day) than the 7/8 HG (31.5 ± 0.5 MJ /day). In conclusion, although the primiparous 3/4 HG were heavier than the 7/8 HG and had a higher body condition score, no differences in milk produced up to 60 days postpartum were observed. The higher energy diet during the postpartum period increased energy balance, resulting in higher production of milk fat, protein, and lactose. |

This study aimed to evaluate the effect of different planting densities and phosphorus fertilization on yield, chemical and mineral composition of Pornunça (Manihot sp.) cultivated under rainfed system, from May 2010 to October 2011. It was adopted the randomized blocks design in a factorial 4 x 4 with three replications, 4 spacing (1.5 x 1.5, 1.5 x 2.0, 2.0 x 2.0 and 2, 5 x 2.0 meters) and 4 phosphorus levels (0.0, 56.66, 113.32 and 169.98 g plant-1 superphosphate). For the total dry mass (TDM) of Pornunça there was effect (P=0.023) isolated from different plant spacing used, and the spacing 1.5 m x 2.0 m provided greater TDM. The planting spacing and phosphorus fertilization showed interaction effect (P<0.05) in the chemical composition only for organic matter and mineral composition presented individual effect for phosphorus levels in the soil and in the phosphorus content of Pornunça plant. For the other variables, there was no effect on the interaction and individual factor (planting spacing and phosphorus fertilization). In dry conditions, planting spacing influences the dry matter forage production and organic matter Pornunça, presented greater value for both the spacing of 1.5 m x 2.0 m. Fertilizing with simple superphosphate increases soil organic matter of Pornunça, until the dosage of 56.66 g plant-1 in the spacing of 1.5 m x 2.0 m, and linearly for the phosphorus content of the plant used regardlessof spacing. |
