Intake, digestibility, water balance, ruminal dynamics, and blood parameters in sheep fed diets containing extra-fat whole corn germ

Intervalo de referência de parâmetros bioquímicos de ovelhas lactantes nos trópicos

“…Fructosamine is a product of glycation of plasma proteins. Quantifying fructosamine concentration is important for energy metabolic evaluation, as it depends on the mean glucose concentration and protein half-life, without being subjected to changes due to transient hyperglycemia, as showed C. F. Silva et al (2022) Triglycerides were 22% below the reference at the lower threshold and 43.3% above the upper threshold (Table 2). The concentration of triglycerides reduces at the beginning of lactation compared to pregnancy, due to the increase in energy input for milk production, milk fat synthesis, in addition to the lower reserve of available free fatty acids (Pesántez-Pacheco et al, 2019).…”

Economic viability of feedlot of sheep fed diets containing corn grain or extra-fat whole corn germ associated or not with spineless cactus

“…An ingredient that has been studied as a source of protein and lipids in diets for ruminants is extra-fat whole corn germ (EFWCG), which represents a byproduct of the bioethanol production process. Silva et al (2022) evaluated the impact of replacing ground corn with EFWCG on the intake, digestibility of nutrients, water balance, ruminal dynamics and blood variables of sheep and recommended the total replacement of ground corn by EFWCG. According to Morais et al (2021), corn is an international commodity that can increase ruminant production costs.…”

“…3), it was found that diets containing SC and EFWCG as the main source of energy promoted higher production rates than diets with SC and corn as an energy source. The EFWCG has a high ether extract level (Silva et al, 2022), and the SC is rich in non-fiber carbohydrates (starch, for example) (Silva et al, 2021). 1 extra-fat whole corn germ.…”
