Resumo: | The expansion of the biofuel industry has generated increased availability of glycerol, which can be used as an ingredient in the ration of dairy cows. This study aimed to determine the effects of glycerol on DMI, milk production, production of SCFA in the rumen, blood parameters, selective consumption and feeding behavior of dairy cows periparturientes. Twenty-six multiparous Holstein cows were paired according to performance in the previous lactation and expected date of calving and fed diets containing glycerol or high moisture corn from -28 to +56 DRDP. Glycerol was included in 11.5 and 10.8% of total DM in the diet pre-and post-partum respectively. CMS has not changed (P> 0.05) by feeding with glycerol both pre-partum (14.9 vs. 14.6 kg / day, vs control. glycerol) and the post-partum (19.8 vs. 20.7 kg / day, vs control. Glycerol), as well as production (35.8 vs. 37 kg / day, vs control. glycerol) and milk composition did not differ (P> 0.05) between treatments. The concentration of blood glucose was reduced (P <0.05, vs 59.1. 53.4 mg / dL vs control. glycerol) and ABHB blood was elevated (P <0.05, 0.58 vs. 0.82 mmol / L vs control. glycerol) in cows fed glycerol during pre-partum. The concentration of NEFA in the blood did not differ (P> 0.05) between experimental groups in the pre-partum, and no effect (P> 0.05) on the glycerol blood parameters during the postpartum period. The total concentration of SCFA in rumen (mmol / L) did not differ (P> 0.05) between treatments, but increased (P <0.05) in the molar proportion of propionate (22.7 vs. 28.6% vs control. Glycerol) and butyrate (11.5 vs. 15.3% vs control. glycerol) and reduced (P <0.05) in proportion molar acetate (61.5 vs. 51.5% vs control. glycerol) in cows fed with glycerol. In relation to the selective consumption and ingestive behavior, there increase (P <0.05) the rate of DMI (94.2 vs. MS 144.4 g / h vs. control. glycerol) and preferential consumption (9.2 vs. 17.8% vs control. glycerol) long particle with glycerol in the diet, but decreased (P <0.05) the rate of CMS short particles (383.8 vs. MS 332.5 g / h vs. control. glycerol) and very short (173.9 vs. MS 129.8 g / h vs. control. Glycerol) and increased (P <0.05) in rejecting short particles (42 vs. 37.3% vs control. glycerol) and very short (17.9 vs. 13.6% vs control. glycerol) during pre-partum. No effect (P> 0.05) of treatments on the selective use of particles of the diet in the postpartum period and also on the feeding behavior throughout the experimental period. The data obtained in this study indicated that replacing corn wet grain by glycerol in diets for dairy cows was periparturientes satisfactory. |

Objetivou-se nesse estudo determinar os efeitos do glicerol sobre o CMS, produção de leite, produção de AGCC no rúmen, parâmetros sanguíneos, consumo seletivo e comportamento ingestivo de vacas leiteiras periparturientes. Vinte e seis vacas multíparas da raça Holandesa foram pareadas de acordo com o desempenho na lactação anterior e data prevista de parição, e alimentadas com dietas contendo glicerol ou milho grão úmido desde -28 até +56 DRDP. O glicerol foi incluído em 11,5 e 10,8% do total da MS nas dietas pré e pós-parto, respectivamente. O CMS não foi alterado (P>0,05) pela alimentação com glicerol tanto no pré-parto (14,9 vs. 14,6 kg/dia, controle vs. glicerol) quanto no pós-parto (19,8 vs. 20,7 kg/dia, controle vs. glicerol), assim como a produção (35,8 vs. 37 kg/dia, controle vs. glicerol) e composição de leite não diferiram (P>0,05) entre os tratamentos. A concentração de glucose no sangue foi reduzida (P<0,05; 59,1 vs. 53,4 mg/dL, controle vs. glicerol) e de ABHB no sangue foi elevada (P<0,05; 0,58 vs. 0,82 mmol/L, controle vs. glicerol) nas vacas alimentadas com glicerol durante o pré-parto. A concentração de AGNE no sangue não diferiu (P>0,05) entre os grupos experimentais no pré-parto, e não houve efeito (P>0,05) do glicerol sobre os parâmetros sanguíneos durante o pós-parto. A concentração total de AGCC no rúmen (mmol/L) não diferiu (P>0,05) entre os tratamentos, mas houve aumento (P<0,05) na proporção molar de propionato (22,7 vs. 28,6%, controle vs. glicerol) e butirato (11,5 vs. 15,3%, controle vs. glicerol) e redução (P<0,05) na proporção molar de acetato (61,5 vs. 51,5%, controle vs. glicerol) nas vacas alimentadas com glicerol. Em relação ao consumo seletivo e comportamento ingestivo, houve aumento (P<0,05) na taxa do CMS (94,2 vs. 144,4 g MS/h; controle vs. glicerol) e no consumo preferencial (9,2 vs. 17,8%; controle vs. glicerol) de partículas longas na dieta com glicerol, porém houve redução (P<0,05) na taxa do CMS de partículas curtas (383,8 vs. 332,5 g MS/h; controle vs. glicerol) e muito curtas (173,9 vs. 129,8 g MS/h; controle vs. glicerol) e aumento (P<0,05) na rejeição de partículas curtas (42 vs. 37,3%; controle vs. glicerol) e muito curtas (17,9 vs. 13,6%; controle vs. glicerol) durante o pré-parto. Não houve efeito (P>0,05) dos tratamentos sobre o consumo seletivo de partículas da dieta no pós-parto e também sobre o comportamento ingestivo durante todo o período experimental. Os dados obtidos na presente pesquisa indicaram que a substituição do milho grão úmido pelo glicerol em dietas para vacas leiteiras periparturientes foi satisfatória.Made available in DSpace on 2014-07-29T15:13:41Z (GMT).

The expansion of the biofuel industry has generated increased availability of glycerol, which can be used as an ingredient in the ration of dairy cows. This study aimed to determine the effects of glycerol on DMI, milk production, production of SCFA in the rumen, blood parameters, selective consumption and feeding behavior of dairy cows periparturientes. Twenty-six multiparous Holstein cows were paired according to performance in the previous lactation and expected date of calving and fed diets containing glycerol or high moisture corn from -28 to +56 DRDP. Glycerol was included in 11.5 and 10.8% of total DM in the diet pre-and post-partum respectively. CMS has not changed (P> 0.05) by feeding with glycerol both pre-partum (14.9 vs. 14.6 kg / day, vs control. glycerol) and the post-partum (19.8 vs. 20.7 kg / day, vs control. Glycerol), as well as production (35.8 vs. 37 kg / day, vs control. glycerol) and milk composition did not differ (P> 0.05) between treatments. The concentration of blood glucose was reduced (P <0.05, vs 59.1. 53.4 mg / dL vs control. glycerol) and ABHB blood was elevated (P <0.05, 0.58 vs. 0.82 mmol / L vs control. glycerol) in cows fed glycerol during pre-partum. The concentration of NEFA in the blood did not differ (P> 0.05) between experimental groups in the pre-partum, and no effect (P> 0.05) on the glycerol blood parameters during the postpartum period. The total concentration of SCFA in rumen (mmol / L) did not differ (P> 0.05) between treatments, but increased (P <0.05) in the molar proportion of propionate (22.7 vs. 28.6% vs control. Glycerol) and butyrate (11.5 vs. 15.3% vs control. glycerol) and reduced (P <0.05) in proportion molar acetate (61.5 vs. 51.5% vs control. glycerol) in cows fed with glycerol. In relation to the selective consumption and ingestive behavior, there increase (P <0.05) the rate of DMI (94.2 vs. MS 144.4 g / h vs. control. glycerol) and preferential consumption (9.2 vs. 17.8% vs control. glycerol) long particle with glycerol in the diet, but decreased (P <0.05) the rate of CMS short particles (383.8 vs. MS 332.5 g / h vs. control. glycerol) and very short (173.9 vs. MS 129.8 g / h vs. control. Glycerol) and increased (P <0.05) in rejecting short particles (42 vs. 37.3% vs control. glycerol) and very short (17.9 vs. 13.6% vs control. glycerol) during pre-partum. No effect (P> 0.05) of treatments on the selective use of particles of the diet in the postpartum period and also on the feeding behavior throughout the experimental period. The data obtained in this study indicated that replacing corn wet grain by glycerol in diets for dairy cows was periparturientes satisfactory. |
