Energy requirement

ENERGY REQUIREMENT

  • Energy plays an vital role is goat diets which affects the overall productivity and utilization of other nutrients.
  • An average energy requirement for maintenance is 101 kcal ME/kg W0.75/day.
  • While for pregnancy it is 180 kcal ME/kg W0.75/day.
  • The daily energy requirement for milk production is found to be 1220 kcal/ME/kg for 4% fat corrected milk (FCM).
  • In addition to this, energy is necessary for increased activity, type of terrain, amount of vegetation on range and distance travelled for grazing.
  • The stall fed goats with minimum activity, requires, basic maintenance level in their diets, however for light activity, goats require 25% more energy.

Grasses like Bajra Napier contain 50% TDN and supply the energy need of the goat

  • The goats grazing in hilly area needs an increase of about 50% over and above maintenance requirements.
  • Energy requirement for growth have been found to be 7.25 kcal ME/g of gain in body weight.

Sorghum is commonly grown dense and cut after 75 days as a feed for goats. It is a source of energy (TDN-55 to 60%on DMB)

  • The diets deficient in energy causes growth retardation, delayed puberty, decrease in fertility rate and also lowers milk production.
  • Prolonged energy deficiency in goats diet may loose the strength of resistance to infections and parasitic diseases.

Sorghumis grown upto grain formation stage,then cut and fed as a source of energy for goats

  • On the contrary excessive energy intake which leads to fat deposition is known to reduce quality of goat skin.
