Protected fat and variable level of protein in diets of crossbreed cows in early lactation

Souza Júnior, Alcy Heleno de; Lana, Rogério de Paula; Teixeira, César Roberto Viana; Gionbelli, Mateus Pies; Veloso, Cristina Mattos; Rennó, Luciana Navajas.

Current study evaluated the inclusion of protected fat and different levels of crude protein (CP) in the diet of crossbreed cows in early lactation. Twelve cows were distributed in a 4 x 4 factorial design, with four treatments (12 or 16% CP, with or without MEGALAC-E®). Statistical analyzes with ANOVA and Pearson’s linear correlation procedures were performed. Protected fat did not affect intake of dry matter (DM) and organic matter (OM) (p > 0.05). Increased CP raised consumption of CP and EE and decreased the non-fiber carbohydrates (NFC; p <0.05). Protected fat increased (p <0.05) the digestibility of DM, OM, CP and ashes in the lower protein content. CP increase raised the level of blood and urinary urea (p < 0.05). There was no difference...

Settlement performance evaluation of longitudinal settling basins - A case study on Golfaraj and Iry-Siah Rud pump stations, Iran

CIGR Journal

Mahtabi, Ghorban; Hoseinzadeh Dalir, Ali; Fazelifard, Mohamad Hasan.

One of the most important elements of river intake is settling basins for water sediment removal. Settling basins play an important role in supplying appropriate water for irrigation networks and power plants. Therefore, it is necessary to design them carefully based on the local conditions. Our objectives were to determine the properties of sediments entering into the intake systems of two pump stations (Golfaraj and Iry-Siah Rud) by sampling the water suspended load in different points of the systems and to investigate the performance of settling basins in Iran. The suspended load samples were taken from sections before and after the settling basins at three depths of 0.2 y, 0.6 y, and 0.8 y (y is the depth of the cross section from the water surface)....

Sierra-Montoya,E.; Barahona-Rosales,R.; Ruiz-Cortés,Z.T..

ABSTRACT It is widely accepted that selection for high milk yield in dairy cows has negatively affected their reproductive performance. After calving, dairy cows experience a nutritional imbalance due to an asynchrony in the occurrence of the lactation and dry matter intake peaks. In the tropics, this situation is exacerbated due to poor quality and/ or availability of the diet. A study was carried out to describe the nutritional and reproductive behavior of two-to-four parturition crossbred cows (Gyr (Bos indicus) x Holstein (Bos taurus)) divided in two groups according to their calving to first service interval (CFSI): Group 1: ≤50 days CFSI, n=7; Group 2: ≥50 days CFSI, n=8. Animals were grazing in an intensive silvopastoral system (ISS) based on...

ABSTRACT The aim of this paper was to evaluate the effects of including virginiamycin (VM), sodium monensin (MON) or the association (VM+MON) in the energetic mineral supplement, on the intake and performance of beef cattle on pasture. Forty Nellore heifers with 24 months of age and initial body weight (BW) of 251.5±16.6kg, were distributed in four treatments in a randomized block design. Treatments consisted of adding VM, MON or VM+MON to the supplement (CONT). Additive concentrations were defined to reach a dose of 40 to 45mg/100kg BW. The herbage allowance was not a limiting factor for the animals’ intake. Supplement intake was lower than expected, with 33.0, 18.8 and 26.3mg per 100kg BW for VM, MON and VM+MON, respectively. Dry matter intake (DMI,...

Saturated aliphatic hydrocarbons (n-alkanes) were extracted from feed, orts, and bovine fecal samples using disposable, plastic 5mL-syringes as an alternative material to disposable columns, which are normally used in the liquid-solid extraction phase of n-alkanes. For both methods, the n-alkane extracts (carbon chain length between 31 and 36 atoms) were identified using gas chromatography. The linear regression between methods were: 1) feces: column Alkane=2.63+0.92×syringeAlkane [r²=0.94, square root of the mean square error (RMSE)=13.7mg kg-1, n=30] from which the intercept and the slope did not simultaneously differ from zero and unity (P>0.05), respectively; 2) feeds: column Alkane=0.36+1.12×syringeAlkane (r²=0.85, RMSE=1.9mg kg-1, n=21) from which...
