Small intestine growth and morphometry in piglets weaned at 7 days of age. effects of level of energy intake.
Two trials involving a total of 56 pigs were conducted to examine the effects of weaning at 7 d of age (trial 1) and of energy intake level and length of post-weaning underfeeding period (trial 2) on small intestinal (SI) development and morphometry. At 3 d after weaning, weight of the SI and mucosa (g/kg body weight) and villous height along SI were reduced by 20, 36 and 41%, respectively, com...
متن کاملThe effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age.
Environmental enrichment can be a useful tool to reduce belly nosing behaviors in early weaned piglets. The aim of this study was to assess the effect of environmental enrichment on behavior, salivary cortisol, and productivity of piglets weaned at 14 days of age. The study assigned 112 piglets (line Camborough 22 of PIC) into 2 treatments, control and enriched, and observed them for 192 hr in ...
متن کاملPerformance and Measures of Stress in Lambs Weaned at 45 and 90 Days
A study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of Zandi lambs. The lambs were weaned at 45 and 90 days of age. The body weights and average daily gain (ADG) were monitored during the experimental period and 5 months of age. Cortisol, glucose, blood urea nitrogen (BUN) and lamb behavior (agitation, vocalization) were recorded bef...
متن کاملEffect of environmental enrichment at two stages of development on belly nosing in piglets weaned at fourteen days.
The incidence of belly nosing-related behaviors was studied in 480 piglets weaned at 14 d and provided with environmental enrichment during preweaning, postweaning, or both. Pen enrichment was achieved by providing a foam rubber mat on the pen wall (nose), rubber nipples (suck), a Bite-Rite Tail Chew (bite), a soil-filled tray (root), or no enrichment (control). Instantaneous scan sampling obse...
متن کاملEffect of environmental enrichment and breed line on the incidence of belly nosing in piglets weaned at 7 and 14 days-of-age
The effect of enrichment and breed line on belly nosing in early-weaned pigs was investigated over two studies. In a preliminary study, 291 piglets were weaned at 7 days-of-age and observed over two consecutive days (pigs ranged from 17 to 30 days-of-age at time of observation). Piglets were fed a liquid milk replacer diet for either 7 or 14 days following weaning. Pen environment was enriched ...
