Indigestible neutral detergent insoluble fiber (iNDF) is made up of the cellulose and hemicellulose fractions linked with lignin. The NDF content of the diet affects dry matter intake, nutrient digestion and the productive performance of lactating cows. Similarly, the concentration of starch in diets influences the intake and digestion of nutrients in a way that influences the productive …
The transition period is extremely challenging in the productive cycle of dairy cows, where a carefully diet formulation may improve performance of subsequent lactation as well as animal health. Among challenges for a successful adaptation during this period is a reduction in dry matter (DM) intake. The feed intake decreases from 30 to 35% during the last 3 wks before parturition, whereas…
Energy and protein nutrition of ruminants present as major cost of feed for ruminants. Special interest has been given to the study of rumen nitrogen metabolism in dairy cows, given the cost of protein sources in diets. The evaluation technical of ruminal metabolism and especially estimation of microbial protein synthesis has been questioned, mainly by difficulties in estimating the post …
The objective of the current study was to evaluate the effects of supplemental omega-3 and omega-6 fatty acids (FA) sources on cellular immune function of transition dairy cows. Animals were randomly assigned to receive one of four diets: Control (CON; n=11); Whole flaxseed (WF, omega-3 FA source; n=11), 60 and 80 g/kg of WF (diet DM basis) during pre and post-partum, respectively; Whole …

Indigestible Neutral Detergent Fiber (iNDF) is composed of cellulose and hemicellulose fractions bound to lignin. The iNDF content of the diet affects dry matter intake, nutrient digestion, and productive performance of lactating cows. Similarly, the starch concentration in diets influences nutrient intake and digestion, potentially affecting the productive performance of lactating cows. …
Making the enzymatic activity more efficient in ruminants is still little explored since the association of exogenous enzymes with organic minerals has been widely used in monogastric nutrition. The objective of this study was to evaluate the association of proteinate microminerals with amylolytic enzymes in ruminant supplementation, and their effects on nutrient intake, ruminal fermentat…
Neutral detergent fiber (NDF) has been widely studied since the initial effortproposed by Peter Van Soest in quantifying and categorizing carbohydrates in the 1970sand 1960s. The knowledge on dietary NDF is critical for ruminant nutrition as the NDFfraction consists of the slow fermentation portion of feeds with the potential of filling therumen and limiting dry matter intake. In addition…
Some feed additives can be used in ruminant diets as growth promoters in order to improve the productive performance and feed efficiency of animals. However, due to scientific and public concern about the indiscriminate use of antibiotics, the increase in antimicrobial resistance in some bacteria, the emergence of superbugs, and the prohibition of antibiotic use in animal nutrition by the…
It is extremely important to know the carbohydrates used in feeding dairy cows and their effects on productive performance; insoluble neutral detergent fiber (NDF) is required in the composition of the diet and makes up a large part of the roughage proportion and has the potential to fill the rumen and limit dry matter intake. Furthermore, the indigestible fraction of NDF (iNDF) is charac…

The aim of this study is to evaluate neutral detergent fiber digestibility (NDFD) using the in situ and in vitro methodologies for corn silage with different cutting heights, corn plant fractions, and experimental diets, as well as compare the uNDF in situ 288 h and in vitro 240 h for the same samples. The hypothesis of this experiment is that the NDFD is proportionally and negatively ass…
The aim of this study is to investigate the effects of different levels of indigestible neutral detergent fiber (iNDF) in corn silage (CS) and TMR on the ruminal degradability of dry matter (DM) and neutral detergent fiber (NDF), and to compare iNDF content of CS and TMR when analyzed with in situ (288 h) or with in vitro (240 h) methods. The hypothesis of this experiment is that the degr…
This study aimed to evaluate the effects of molasses addition in whole-plant soybean ensiling with different phenological stages on crude protein (CP) in situ degradability. The hypothesis of the experiment is that molasses as a water soluble carbohydrates source increase soybean silage CP in situ degradation regardless the phenological stage. Treatments were arranged in a 3 × 2 factorial…
The addition of enzymes in ruminant diet may manipulate ruminal fermentation and become an alternative to increase feed conversion rate. There are few studies in literature evaluating amylolytic enzyme in ruminant nutrition and experimental conditions largely vary between experiments which impairs comparison among studies and difficult a conclusion to dietary amylase response. In recent l…
