| Glycerol plays multi-functional roles in cellular physiology. Other than forming the backbone molecule for glycerophospholipid and triglyceride (TG), glycerol acts as an energy substrate for glycolysis. Spermatozoa are known to utilize glycerol for energy production, but there are no reports of this in oocytes. In this study, the value of glycerol as an energy substrate for bovine oocyte maturation (Exp. 1) and the gene expression of glycerol kinase (GK), an enzyme crucial for cellular glycerol utilization, in bovine oocytes and early embryos (Exp. 2) were examined. In Exp. 1, in vitro maturation (IVM) was conducted using synthetic oviduct fluid supplemented with/without glucose (1.5 mM) and/or glycerol (1.0 mM), and maturation rate, degree of cumulus... |

| In the central-west region of Brazil, the seasonal distribution of rainfall generates an imbalance in the production of fodder. Moreover, during the dry period, the nutritive value of the fodder decays, due to the advance in the maturation of the plants. To alleviate this problem, several alternatives have been pointed out and used to supply food deficits in herds where basal feeding is like fodder plants, and the most usual is a conservation of fodder for the manufacture of silage. The objective of this study was to evaluate the effect of the addition of additives on a chemical composition of the silage of Urochloa brizantha cv. BRS Piatã. The piatã grass used to make the silage was established in the experimental area of Embrapa Agrossilvipastoril in... |

| The use of sugarcane silage is a feasible option for shortage of forage in pastures, increasing the losses during the fermentation process. However, the use of additives is required due to the high level of soluble carbohydrates, as well as the large number of yeasts that promote alcoholic fermentation with high CO2 production, increasing losses during the fermentation process. This experiment aimed to evaluate the effects of calcium oxide and crude glycerin on the chemical composition of sugarcane silage. |

| O mundo busca fontes alternativas de energia, bem como aproveitamento de resíduos industriais considerados poluentes. Este trabalho avaliou a utilização da massa seca da parte aérea de sorgo biomassa e de capim elefante na forma in natura e acrescidas de óleos residuais (glicerina e bio-óleo) para geração de energia. Para tanto, foi implantado um experimento no delineamento inteiramente ao acaso com três repetições, composto por 10 tratamentos: sorgo biomassa, capim elefante e as misturas destas biomassas com duas concentrações de bio-óleo e duas de glicerina. Foi avaliada a umidade, voláteis, cinzas, carbono fixo e poder calorífico superior (PCS). Os dados foram submetidos à análise de variância e as médias dos tratamentos foram agrupadas pelo teste de... |

| O objetivo deste trabalho foi avaliar o efeito da substituição do milho pela glicerina bruta (GB) sobre os parâmetros nutricionais e o desempenho de bovinos de corte em pastagem de Urochloa brizantha 'Marandu', no período seco. Para a avaliação dos parâmetros ruminais, foram utilizados cinco bovinos da raça Nelore não fistulados, com peso corporal (PC) inicial de 331,7±29,6 kg, distribuídos em delineamento em quadrado latino 5x5. Para a avaliação do desempenho, foram utilizados 30 bovinos, com PC médio de 312,4±23,3 kg, distribuídos em delineamento inteiramente casualizado. Avaliaram-se suplementos concentrados (20% de proteína bruta) com 0, 33, 66 e 100% de GB em substituição ao milho, fornecidos na quantidade de 4,0 kg por animal por dia. Os consumos de... |

| This work was carried out to study corn substituting by glycerin levels on animal behavior, feeding and rumination efficiency of Purunã young bulls finished in feed-lot. It was utilized 40 bulls Purunã breed with 208.8 ± 33.75 kg and 8 months old. The diets were: without glycerin - G00, 6% of glycerin – G06, 12% of glycerin – G12 and 18% of glycerin – G18. Dry matter intake was similar among diets. On the other hand, NDF intake decreased linearly with glycerin levels supplementation in the diets. FEDM and FENDF were similar among diets. REDM and RENDF were not changed due glycerin levels. Glycerin changed activities durations of bulls. Glycerin did not affect feed frequency. At contrary, rumination frequency was reduced linearly with glycerin inclusion.... |

| Mead production represents a possible economic alternative to honey producers that intend to obtain honey products with surplus value. From that the present work aims to study the influence of using different production scales on the quality of the final mead obtained and on the process performance. Increasing the production scale almost ten times (1.5 to 20 L), some differences were observed. Maximum specific growth rates equal to 0.045 and 0.038 h-1 were obtained for fermentations carried out at 1.5 and 20 L, respectively. The time course of glucose and glycerol were similar for both production scales. Nevertheless, slight differences at the end of the fermentations were observed for fructose and acetic acid. In relation to ethanol, a higher final... |

| This trial aimed to evaluate the inclusion of 10% of crude glycerin associated with roughage sources on the quality of meat aged for 1, 7 or 14 days post mortem of Nellore young bulls. Thirty feedlot animals (n = 10) with initial body weight of 416.70 ± 24.74 kg and 18 months of age were assigned to three treatments: corn silage (CS), sugar cane (SC) and sugar cane bagasse (CB), using a completely randomized design. After 85 days of feeding, animals were slaughtered with 554.51 ± 38.51 kg. Samples of longissimus muscle were collected, after carcass chilling, and vacuum-packed. Diets influenced pH, meat color and subcutaneous fat (SF) (p > 0.05). Animals fed CS showed higher values of b* in SF (p < 0.05). Differences were not found in the meat fatty... |

| This review provides a summary of the research conducted on the use of crude glycerol, the major byproduct of the biodiesel industry, as substrate for anaerobic co-digestion and production of biogas. In general, for every 100 kg biodiesel produced, approximately 10 kg crude glycerol is generated. Because this glycerol is expensive to purify for use in food, pharmaceutical, or cosmetic industries, biodiesel producers must seek alternative methods for its disposal. Several studies have demonstrated that the use of crude glycerol as a C source for fermentation and biogas generation is a promising alternative use for this waste material. The high C content of glycerol increases the C:N ratio in the mixture, avoiding the inhibition of the process by the excess... |
