Autores: Souza,Paulo Henrique de; Faturi,Cristian; Rodrigues,Luiz Fernando de Souza; Silva Filho,Ednaldo da; Rêgo,Aníbal Coutinho do; Rodrigues Filho,José Adérito.
Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes.

Autores: Gomes,Helen Fernanda Barros; Souza,Samuel Figueiredo de; Oliveira,Daiana de; Biagioli,Bruno; Teixeira,Izabelle Auxiliadora Molina de Almeida; Resende,Kleber Tomás de.
ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For the composition of orts, differences were measured only in the ether extract fraction. Animals fed the ad libitum diet increased their intake of ether extract and energy, crude fiber, neutral detergent fiber, and acid detergent fiber. Thus, they had a preference for consuming the fibrous and...

ABSTRACT The objective of this study was to determine the optimal level of dried brewers' grains (DBG) to replace soybean meal in diets for lactating Holstein cows. Five cows, around 88±28 days in milk, were distributed in a 5 × 5 Latin square design and fed diets containing different levels of DBG (0, 25, 50, 75, and 100%). The forage:concentrate ratio of the diet was 50:50. Feed intake, dry matter, nutrient digestibility, microbial synthesis, milk production and composition, and the economic viability of the diets were evaluated. There was reduction in dry matter intake and, consequently, in crude protein and non-fiber carbohydrates with increased levels of DBG. This occurred due to physical limitation of rumen caused by increased neutral detergent fiber...

Alternative sources of protein for lactating cows were evaluated in this study with respect to intake, digestibility, milk yield and milk composition. Eight multiparous Holstein/Gyr cows were simultaneously distributed in two 4 × 4 latin squares. Each experimental period lasted 21 days (14 days for adaptation and seven days to collect data and samples). Three protein sources, cottonseed meal, semi-integral soybean meal and corn steep liquor were evaluated and soybean meal was used as a control. When the corn steep liquor was used, lower intakes of dry matter, organic matter, crude protein and total digestible nutrients were observed compared with soybean meal. Animals that consumed corn steep liquor had a lower milk yield than those fed soybean meal, and...

ABSTRACT: Owing to the lack of information in the literature about the ideal feeding frequency adopted by feedlot systems, this study was designed to evaluate the effect of different feeding frequencies on performance, carcass traits, feeding behavior and rumen morphometrics of Nellore cattle. Forty-eight yearling bulls were housed in individual pens with an average initial body weight of 358.2 kg. The experiment was designed as a completely randomized block and the treatments were the feeding of cattle one, two, three, or four times daily (n = 12 per treatment). Orthogonal contrasts were used to assess linear, quadratic and cubic relationship between feeding frequency and the dependent variable. As feeding frequency increased, final body weight (p = 0.03)...

Settlement performance evaluation of longitudinal settling basins - A case study on Golfaraj and Iry-Siah Rud pump stations, Iran
Provedor de dados: Agricultural Engineering International : The CIGR e-journal
Autores: 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)....

Autores: FERNANDES,TATIANE; ZAMBOM,MAXIMILIANE A.; CASTAGNARA,DEISE D.; SOUZA,LEILIANE C.; DAMASCENO,DAIANE O.; SCHMIDT,EMERSON L.
The aim of this study was to determine the best level of utilization of dried waste of cassava starch extraction (WCSEd) as a substitute for corn for lactating cows. Four lactating cows were fed diets with increasing levels (0%, 33%, 66% and 100%) of WCSEd as a substitute for corn. The intake and digestibility of dry matter and nutrients, milk production and composition, blood parameters of glucose and urea and microbial synthesis of the diets were evaluated. There was a reduction in dry matter intake, organic matter, ether extract and total carbohydrate, and increased intake of acid detergent fiber. Nutrient digestibility was not affected while the synthesis of microbial protein increased. These changes resulted in reduced milk production, without...

Reproductive behavior of crossbred dairy cows grazing an intensive silvopastoral system under tropical dry forest conditions
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: 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,...

ABSTRACT: The objective of this study was to determine the leaf tissue flows in Italian ryegrass (Lolium multiflorum Lam.), in different phenological stages, grazed by lambs, and managed under three herbage allowances (6, 9 and 12 kg DM/100 kg body weight under rotational stocking method. The experimental design was completely randomized, with repeated measures arrangement. Forage allowances determined similar growth and intake flows, actual and potential utilization efficiencies of grass and they were different in the phenological stages of Italian ryegrass. The intake of leaf blade, as a percentage of body weight, was higher in the 12% herbage allowance. Considering leaf tissue flows, Italian ryegrass can be managed in forage allowances that vary between...

Comparing plastic syringes and disposable columns to extract n-alkanes in forage and concentrate feeds
Provedor de dados: Ciência Rural
Autores: Oliveira,Dimas Estrasulas de; Tedeschi,Luis Orlindo.
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&gt;0.05), respectively; 2) feeds: column Alkane=0.36+1.12×syringeAlkane (r²=0.85, RMSE=1.9mg kg-1, n=21) from which...
