Additives in ensiling palisade grass managed under grazing intensities Animal Sciences
Macedo, Felipe Barros; Luz, Pedro Henrique de Cerqueira; Faria, Letícia de Abreu; Braga, Gustavo José; Peternelli, Maurício; Herling, Valdo Rodrigues.
Conservation of summer forage excess represents a management strategy to meet animals' needs for dry matter in the shortage period, but has been poorly studied. Silage can be used for this purpose. This study analyzed the production of palisade grass silage from pasture subjected to different grazing intensities with and without additive, determining losses by gases and effluents and chemical composition of silage. The experiment was a 4 x 3 factorial completely randomized design, with four replications. The factors were: 1st – herbage allowance of 5% (5 kg dry matter 100 kg-1 of animal weight day-1), 10, 15 and 20%. The pasture was managed under rotational stocking with 35-day grazing cycles (7 days of occupation and 28 days of rest) and 2nd - additives:...

Diet digestibility and performance of dairy cows supplemented with live yeast Scientia Agricola
Bitencourt,Luciene Lignani; Silva,José Ricardo Martins; Oliveira,Bruno Menezes Lopes de; Dias Júnior,Gilson Sebastião; Lopes,Fernanda; Siécola Júnior,Sancho; Zacaroni,Ozana de Fátima; Pereira,Marcos Neves.
Dietary yeast supplementation may improve the digestive efficiency of ruminants, but responses depend on the yeast strain and the diet composition. Corn silage and citrus pulp are usual carbohydrate sources for dairy cows in southeast Brazil. This study evaluated the supplementation of dairy cows fedding on corn silage-citrus pulp-based diets with Saccharomyces cerevisiae CNCM I-1077 (Lallemand SAS, Toulouse, France). Twenty multiparous, midlactation Holstein cows were assigned to two treatments in crossover design. Treatments were: live yeast on oyster meal capable of supplying a daily minimum of 1 × 10(10) CFU per cow or oyster meal top-dressed at 10 g to the morning meal. Diet contained (% of dry matter): 16.8% crude protein, 30.9% neutral detergent...

Effects of dietary energy and nitrogen supplements on rumen fermentation and protozoa population in buffalo and zebu cattle R. Bras. Zootec.
Franzolin,Raul; Rosales,Fabrício Pini; Soares,Weber Vilas Bôas.
The effects were assessed of two energy sources in concentrate (ground grain corn vs. citrus pulp) and two nitrogen sources (soybean meal vs. urea) on rumen metabolism in four buffaloes and four zebu cattle (Nellore) with rumen cannula and fed in a 4 × 4 Latin square design with feeds containing 60% sugar cane. Energy supplements had no effect on the rumen ammonia concentration in cattle, but ground grain corn promoted higher ammonia level than citrus pulp in buffalo. Urea produced higher ammonia level than soybean meal in both animal species. On average, the buffaloes maintained a lower rumen ammonia concentration (11.7 mg/dL) than the cattle (14.5 mg/dL). Buffaloes had lower production of acetic acid than cattle (58.7 vs. 61.6 mol/100 mol) and higher of...

Performance of Holstein-Zebu cows under partial replacement of corn by coffee hulls Scientia Agricola
Tavares,Anamaria Almeida Costa; Pereira,Marcos Neves; Tavares,Marcelo Rodrigo; Chaves,Márcio Luiz.
Replacement of corn by citrus pulp or coffee hulls explores the potential of dairy cows to digest fiber-rich feedstuffs. However, for the State of Minas Gerais, Brazil, replacing citrus pulp by coffee hulls may reduce milk production costs, since citrus pulp needs to be imported from another state, while coffee hulls are highly available at essentially no cost. The objective of this experiment was to evaluate the performance of crossbred cows fed concentrates containing 25% coffee hulls (Coffee) or 25% citrus pulp (Pulp) as a replacement for ground corn grain (Corn; 47.4% in the concentrate). Forty-two cows were blocked based on milk yield and allocated to one of the three treatments for 56 days, following a 14-day standardization period. Concentrates were...
