ABSTRACT To evaluate the effects of temporary dietary lysine restriction on nursery pigs’ growth performance and its economic viability compared to control diets, 144 piglets (21-d-old) were assigned randomized blocks, with two treatments twelve replicates. The control-lys: level as recommended from 21-32 32-42 days low-lys: 90% control-lys diets. From 42 62 days, all animals received a diet. 2...

In order to evaluate the effect of pre-incubation storage conditions on embryonic development and chick quality of Camperos breeders, 320 hatching eggs were selected. Before the incubation, they were kept for 4 days at a controlled storage and environment. Then, were kept for 21 days in the incubation process with the same technological conditions. Bioproductive performance on biological contro...

The objectives of the present study were to determine the effects of resynchronization with GnRH on Day 21 after artificial insemination (AI) on pregnancy rate and losses of pregnancy in lactating dairy cows. Holstein cows (n=585) on two dairy farms were assigned to one of two treatments in a randomized complete block design. On Day 21 after a pre-enrollment AI, animals assigned to the resynchr...

The dairy cows experience negative energy balance during early lactation and feeding Bypass fat in ration can produce higher milk yield, improved reproduction with better economics. An experiment was planned to evaluate of total mixed (TMR) supplemented @ 100 g/day animals for -21 120 days calving. Total sixteen were divided control group having eight each. effect on production, economics evalu...

PURPOSE To assess the evolution profile of the immunohistochemical expression of stromal constituents over the time-course of wound healing in a murine model. METHODS Surgical wounds were performed in the back of 24 Wistar rats. After three, seven, 14 and 21 days, six rats were euthanized and the wounded histologically processed to assess the immunohistochemical expression of CD3, CD20, CD31,...
