Evolution of weights and growth rate of lives from mothers of low body condition.

Abstract

The objective of the trial was to evaluate the weight and growth of Pampinta lambs maintained at the foot of the mother with a differential feeding (Creep Feeding) with ewes of body condition 1, 1,5. The trial was carried out in units of the Faculty of Agricultural Sciences and Veterinary Sciences, 20 Pampinta sheep and 20 lambs born in the month of September of 2017. The feeding of thelambs was made under unrestricted natural lactation with differential feeding. During the night the lambs separated from their mothers were taken to the food court and received a ration of soy and corn mixture sprinkled with powdered milk.

The results were analyzed by means of ANOVA for a completely randomized design. The variables birth weight (p = 0.0065) and growth rate (p = 0.039) were significantly different between sex, daily weight gain and weight at 45 days were not different between sex.
