Fermentative losses and lactic acid content of elephant grass silages added with macaúba cake

Biosci. j. (Online); 39 (), 2023
Elephant grass is indicated for silage production but requires additives to increase dry matter content because it reduces the production of effluents, potentially improves the fermentation pattern, and preserves the nutrients of the silage. This study aimed to evaluate the effects of including macaúba ...

New bicompartmental model: an application for the production of gases using the in vitro technique

Semina ciênc. agrar; 44 (5), 2023
The purpose of this study was to propose a bicompartmental nonlinear model and to identify the best-performing model between the proposed model and the bicompartmental logistic (BL) mode regarding the quality of fit to the curve of cumulative gas production (CGP) using corn silage, sunflower, and their m...

Yield potential and selection of off-season maize for silage and grain using GT Biplot under limited water and frost

Biosci. j. (Online); 39 (), 2023
Maize silage has been used as a forage reserve strategy for critical periods or continuous use in animal feed. However, new genotypes and their potential must be identified. Thus, this study aimed to evaluate the potential of maize genotypes for silage and grain in one off-season in the midwest region of...

Proposal of a non-linear model to adjust in vitro gas production at different incubation times

Biosci. j. (Online); 39 (), 2023
This work aims to propose a new model named Gompertz-Von Bertalanffy bicompartmental (GVB), a combination of the models Gompertz and Von Bertalanffy. The GVB models is applied to fit the kinetic curve of cumulative gas production (CGP) of four foods (SS – sunflower silage; CS – corn silage; and the m...

Evaluation of chemical silage on egg quality parameters in ISA Brown line laying hens (Gallus gallus domesticus)

Rev. med. vet. zoot; 69 (1), 2022
ABSTRACT In this study we evaluated the inclusion of chemical silage from red tilapia viscera (Oreochromis sp.) in diets for ISA Brown line laying hens (Gallus gallus domesticus) and its influence on nutritional parameters and egg quality. A total of 56 16-week-old laying hens were randomly divided into ...

Fermentation dynamics, nutritional quality, and heating capacity of mixed silages of elephant grass (Pennisetum purpureum Schum) and Leucaena (Leucaena leucocephala)

Leucaena has been used to make mixed silages to obtain nutritional enrichment of the silages. Thus, the inclusion of Leucaena as an additive in mixed elephant grass silages can reduce fermentation losses, and increase the nutritional value and aerobic stability of the mixed silage without changing the fe...

Fermentation profile, aerobic stability, chemical and mineral composition of silages of mango combined with cocoa pod husk meal

The objective was to evaluate the fermentation profile, aerobic stability, chemical composition, and mineral content of silages of mango combined with cocoa pod husk meal. A completely randomized design was adopted, including four levels (65, 70, 75, and 80%) and five repetitions, totaling 20 experimenta...

Triticale silage replaces sorghum silage in finishing of Braford heifers

The aim of this study was to evaluate the effect of sorghum silage substitution with different proportions of triticale silage on the performance and carcass of Braford heifers. Twenty-four Braford heifers were randomly assigned to four diets where sorghum silage was replaced at 0%, 30%, 60%, and 100% fo...

Evaluation of corn hybrids for silage grown in different locations

The aim of this study was to evaluate the yield, morphometric and chemical characteristics, and the digestibility of various corn hybrids cultivated in different locations for silage production. Four corn hybrids were grown: P2866H, P3456H, P30R50VYH and P4285YHR, in four locations, defined as farm A; B;...

Preparação experimental de silagem como recurso didático na disciplina de forragicultura no curso de medicina veterinária do Ifam, Amazonas, Brasil

A silagem pode ser utilizada na alimentação de ruminantes e equídeos, sendo uma alternativa viável em épocas de estiagem. Para a produção de silagem, é importante optar por plantas forrageiras que atendam às necessidades nutritivas dos animais e que possuam características favoráveis para a co...
