Performance and carcass characteristics of beef cattle fed with ammoniated marandugrass hay R. Bras. Zootec.
Roth,Marcella de Toledo Piza; Resende,Flávio Dutra de; Reis,Ricardo Andrade; Siqueira,Gustavo Rezende; Faria,Marcelo Henrique de; Berchielli,Telma Teresinha.
This trial was conducted aiming to evaluate the effects of Brachiaria brizantha vegetative seed harvest residues hay treated with anhydrous ammonia (NH3) or urea, and protein sources on the steers performance, and carcass quality. Twenty-four male beef cattle were (12 F1 Nellore X Aberdeen Angus and 12 F1 Nellore X Red Angus), distributed in four treatments, with six replications. Animal crossbreed type and initial body weight were considered blocks. The diets were: Untreated hay supplemented with non-protein nitrogen (UHNPN); untreated hay supplemented with cottonseed meal (UHCM), hay treated with 5% urea (HTU), hay treated with 3% anhydrous ammonia (HTA) of DM%. Diets were formulated to be isoproteic and isoenergetic. The initial body weight (kg), daily...

Neres,Marcela Abbado; Castagnara,Deise Dalazen; Mesquita,Eduardo Eustáquio; Zambom,Maximilliane Alavarze; Souza,Leiliane Cristine de; Oliveira,Paulo Sérgio Rabello de; Jobim,Clóves Cabreira.
This trial aimed at determining the dehydration curve at nine times (0, 3, 6, 9, 24, 27, 30, 33 and 46 hours after cuting of the plants); the leaf/stem ratio and number of leaves per stem in alfalfa submitted to four managements during the drying process. It was also evaluated the bromatologic composition and in vitro digestibility of the dry matter and cell wall of alfalfa hay before storage. The drying methods applied for alfalfa were the following: drying in the field until 50% DM and drying conclusion in an airy shed; drying in the field without turning; drying with only one turning and drying with two turnings. The experimental design was completely randomized with four drying methods and five replications. Leaf dehydration was faster when compared to...

The effect of ensiling and haymaking on the concentrations of steroidal saponin in two Brachiaria grass species Ciência Rural
Lima,Flavia Gontijo de; Lee,Stephen Thomas; Pfister,James Alan; Miyagi,Eliane Sayuri; Costa,Gustavo Lage; Silva,Roberta Dias da; Fioravanti,Maria Clorinda Soares.
Brachiaria (signalgrass) is now the most widely used tropical grass genus in Central and South America. However, Brachiaria spp. can cause hepatogenous photosensitization in livestock. Steroidal saponins, specifically protodioscin, present in Brachiaria spp. may be responsible for liver injury and subsequent photosensitization. The objective of this study was to determine the effect of ensiling Brachiaria decumbens and Brachiaria brizantha or making hay from Brachiaria decumbens on the concentrations of steroidal saponin in these grasses. Brachiaria grass had no detectable levels of the saponin protodioscin after 24 days of ensiling. In addition, in Brachiaria decumbens, the concentration of the protodioscin decreased 48% over the first three days after...

Use of a conditioning unit at the haymaking of Tifton 85 overseeded with Avena sativa or Lolium multiflorum R. Bras. Zootec.
Castagnara,Deise Dalazen; Neres,Marcela Abbado; Oliveira,Paulo Sérgio Rabello de; Jobim,Cloves Cabreira; Três,Tamara Taís; Mesquita,Eduardo Eustáquio; Zambom,Maximilliane Alavarze.
White oat and ryegrass were overseeded on Tifton 85 pastures for evaluation of dry matter yield (DMY), leaf:stem ratio (L:S), dehydration curves and nutritional value of forages. Dry matter intake and L:S ratio were analyzed using a completely randomized blocks design with five forage growth conditions (single Tifton 85 and intercropped with white oat or ryegrass, and white oat or ryegrass intercropped with Tifton 85), whereas for drying curves, ten dehydration times were tested (0, 4, 8, 24, 28, 32, 48, 52, 56 and 71 hours after harvest) by a 5 × 10 split-plot arrangement (growth conditions of forages as main plot and dehydration times as sub-plots). The nutritive value data were analyzed in a 3 × 3 split-plot trial with single Tifton 85, Tifton 85 - Oat...
