Deck 3 Flashcards
Maximum intake of NDF in the total ration should equal
1.2% of the cows body weight
The energy produced by volatile fatty acids contribute
up to 15% of the maintenance energy of growing pigs and even up to 30% in gestating sows
One of the aims of heifer nutrition is
To have optimum growth of calf at 2 years of age
What is true about cereal grains
The phosphorus content is higher, but the major portion of the total phosphorus is present in the form of phytic acid
The following can support the rumen papillae growth
increasing proportion of starch in feed ration, increasing propionic acid levels in the rumen fluid
In 1st phase of lactation of dairy cows
Redommended crude protein content in dry matter of daily ration is 16-19%
Recommended crude fibre content in dry matter of daily ration is 17-18%
Early lactation refers to
The first 70 days of lactation. Milk production increases rapidly, peaking at 5 to 8 weeks after calving
True or false: during early lactation, the cow could loose as much as 1.5-2 kg body reserves per day. At beginning of this phase, cows will have acieved the peak of dry matter intake
False
Canine colostrum is distinguished by milk essentially by its
Higher protein concentration (more than 2x of milk 2 weeks postpartum), a slightly higher lipid concentration and a lower carbohydrate content
As proportion of concentrates in the diet of ruminants is decreased the proportion of
propionic acid falls and acetic acid rises
Lactating sows during 3-4 weeks of lactation require
6-6.6 kg of feed mixture to meet their energy requirement
The volume of the equine stomach is about
8-10% of the total GIT
The main products of the metabolism of carbohydrates by rumen microorganisms are
Acetic acid, propionic acid, butyric acid, CO2 and methane
Among Omega-3 fatty acids belong
Eicosapentaenoic acid (EPA)
Docosahexaenoic acid (DHA)
Alpha-linolenic acid
Which amino acids are considered as non-essential for pigs?
serine and proline
