Ruminants small test nutrition

Negative energy balance to some extent will occur during :

Early lactation

In ruminants, volatile fatty acids are absorbed mainly in the

Rumen

Reduced rumination can be seen in cows fed :

Concentrates

Colostrum compared to milk had

Less lactose

Forage part of the diet will directly influence

Level of milk fat

Daily intake of feed in dairy cows during lactation is estimated to be

3% of body weight on dry matter basis

Development of the rumination papillae is promoted by the

Butiryc acid

The timing of colostrum feeding is important because

Due to limited time when large molecules can be transported trough intestinal lining

By increasing forage percentage in the ration of dairy cattle we would see

Increased percentage of acetic VFA in rumen content

Average daily weight gain in the intensive beef cattle fattening is

1.1 to 1.3 kg

By increasing the percentage of concentrates in the ration of dairy cattle

the percentage of propionic VFA in rumen content would increase

The optimal pH in the rumen of dairy cows should range between

5.8 - 6.4

Fat content in the diet of dairy cows, if it is too high could negatively influence

Level of milk fat

A negative energy balance in dairy cows is a result of

High demand of energy and insufficient intake of dry matter in the early lactation

Microbial Crude Protein (MCP) is

the protein produced by the microbial synthesis in the rumen

The source of NPN (non protein nitrogen) that is often used in the diet of ruminants is

Urea

What is the name of the volatile fatty acid that provides energy to the rumen wall

Butyric

What is the time point when enzyme secretion in the gut of a newborn calf increases, thereby reducing the ability of antibodies from colostrum to reach the blood?

12h after birth

In the intensive fattening of beef, one the standard systems of nutrition is called

fattening with higher roughage proportion or concentrates

The timing of colostrum feeding is important because

there is a limited time when large lg molecules can be transported through the intestinal lining
