“…A fermentação dos CNF no rúmen contribui para o aumento da produção de ácido propiônico, principal responsável pela síntese de glicose, molécula primer da produção de galactose e lactose, no parênquima da glândula mamária (Paiva et al, 2013). Em razão da grande capacidade de exercer pressão osmótica no lúmen dos alvéolos mamários, a lactose constitui o principal nutriente relacionado à quantidade de leite produzido.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito da alimentação suplementar de resíduos de feijão no desempenho produtivo e nos parâmetros sanguíneos de vacas leiteiras em pastejo. Foram utilizadas oito vacas mestiças, com peso médio de 500 kg, distribuídas em duplo quadrado latino 4×4, alimentadas com alimentação suplementar de 134, 240, 348 e 449 g kg -1 de resíduos de feijão na ração concentrada. Os animais receberam a suplementação após a ordenha no período da manhã e da tarde. A inclusão de resíduos de feijão não alterou os pesos corporais médios e os escores corporais; no entanto, reduziu a produção de leite. Os teores de gordura, proteína bruta, lactose e extrato seco total não foram alterados pela inclusão dos resíduos de feijão. A concentração sanguínea de glicose e colesterol não foi alterada pela adição do resíduo antes do fornecimento de ração concentrada e nem quatro e seis horas após essa alimentação. A inclusão dos resíduos de feijão na ração concentrada de vacas leiteiras em pastejo, com produção média diária de 13 kg, reduz a produção de leite. Todavia, a utilização desses resíduos pouco influencia a composição do leite e os parâmetros sanguíneos.Termos para indexação: Phaseolus vulgaris, produção de leite, qualidade do leite, subproduto. Growth performance and blood parameters of dairy cows subjected to grazing and to a supplementary diet of bean residuesAbstract -The objective of this work was to evaluate the effect of dietary supplement bean residue on growth performance and blood parameters of dairy cows grazing. Eight crossbred cows weighing 500 kg were analyzed, distributed in 4×4 double Latin square, and fed with 134, 240, 348, and 449 g kg -1 of a supplementary diet of bean waste in the concentrated feed. The animals received the supplementation after milking in the morning and in the afternoon. The inclusion of bean residues did not change average body weights and body scores; however, it reduced the milk production. Fat, protein, lactose, and total solid contents (g kg -1 ) were not changed by bean waste inclusion. Blood glycose and cholesterol did not change before the offering of the concentrated feed diet, nor after four to six hours of feeding this diet. The inclusion of bean residues in the concentrated feed of dairy cows subjected to grazing, with a daily average production of 13 kg, reduces milk production. However, the use of these residues has little effect on milk composition and blood parameters.Index terms: Phaseolus vulgaris, milk production, milk quality, byproduct. IntroduçãoPara que o produtor brasileiro seja competitivo, é necessário investir em tecnologias nutricionais que permitam que a bovinocultura leiteira produza leite com alto padrão de qualidade e a custo reduzido.A utilização de subprodutos agroindustriais é uma alternativa para viabilizar um plano nutricional que melhore os índices produtivos de bovinos leiteiros e contribua para a redução dos custos com alimentação; tais resultados são comprovados por diversos autores (Mendes Neto et al., 2007;Maciel e...

“…This deficiency does not meet nutritional requirements, with decreased cell wall digestion and consumption (Wilson & Kennedy, 1996). Thus, crude protein is the most required ingredient after energy for the development of ruminant metabolic functions (Paiva et al, 2013).…”

Association between agronomic characters and hay quality of sweet potato branches

From the perspective of the use of sweet potato branches for animal feed, there is a lack of information on the influence of this action on hay quality. Therefore, the objective was to study the association of sweet potato yield attributes with chemical-bromatological characteristics of hay. Ten sweet potato clones were evaluated, conducted in randomized blocks with five replications. Green and dry mass yield, dry mass content, leaf and stem ratio, total and commercial root yield, and chemical and bromatological characteristics of hay from the branches were determined. Phenotypic correlation and trial analysis between characteristics were estimated. Selection for the highest yield of roots and commercial roots may provide increased hay of crude protein, neutral detergent fiber and acid and total soluble sugars. However, selection for the highest root yield has a negative effect on the starch content of hay and deserves special attention from the breeder.

“…The higher levels of nitrogen and protein allow a greater intake of dry mass by the animals due to ruminal nitrogen deficiency, resulting in lower ruminal microbiota growth. The lack of nutritional requirements causes decrease in cell wall digestion and consumption (Wilson and Kennedy, 1996), where protein is the most required ingredient after energy for the development of metabolic functions of ruminants (Paiva et al, 2013). As for the starch content, the mobilization of sugars from the starch reserves aims to increase the amount of soluble sugars potentially usable for cell metabolism (Zeeman et al, 2010).…”

The objective of this study was to evaluate effect of branch removal on the yield and quality of sweet potato genotypes in different harvesting systems and two growing seasons. Two trials (2014 and 2016/17) were conducted in a randomized block design with three replicates in the factorial scheme composed of: three clones (Brazlândia Rosada, BD-31 TO and BD-65) and five harvesting systems (H): H1- total harvest of branch and root at 120 days after planting (DAP); H2- cut of the branches at 120 DAP, plus regrown branches and roots harvested at 210 DAP; H3 - total harvest of branches and roots at 165 DAP; H4 - cut of the branches at 165 DAP and harvest of regrown branches and roots at 210 DAP and H5- branches and roots total harvest at 210 DAP. For harvesting systems H2 and H4 the total production of branches at the end of the cycle was determined by the sum of the two cuts. The yield, dry matter of shoot and root, chemical-bromatological and nutrient quality were evaluated. The 2014 trial produced higher green mass yield of the branches, while in 2016/2017, higher root yield observed. H2 and H4 were shown to have better quality of the branches regarding the bromatological and nutrient characteristics, being recommended for animal feeding. The systems without regrowth (H3 and H5) allowed better yields and quality of roots, useful for human feeding. In general, the clone Brazlândia Rosada, produced the highest yield of roots and branches; therefore, recommended for planting.
