Article Abstract
The objective of this study was to evaluate the effects of creep feeding during the pre-weaning stage on the performance of piglets at nursery phase, as well as to estimate the economic viability of its application. A total of 125 piglets were exposed to creep feeding and evaluated qualitatively regarding diet intake and quantitatively regarding weight gain. After determining the eaters and non-eaters' piglets, 48 of these animals were evaluated in the nursery phase. Piglets are blocked (initial weigh and sex) and divided into eaters (E, n=24) and non-eaters (NE, n=24). Time to start feed intake, growth performance data and economic viability were analyzed. At pre-weaning phase no weight difference was observed, and only 24.5% of piglets consumed the creep feed after 12 days of exposure. At nursery phase, the E group presented a 250% faster consumption in the first 24 hours of housing, 18.3% greater daily feed intake and 22.0% greater daily gain for whole experimental length, when compared to NE group. The economic evaluation demonstrated a 269% and 225% greater economic profit and return on investment for E. Therefore, the application of creep feeding in pre-weaning improves the piglets' performance during nursery phase and is economically viable.

In pig production, weaning is a critical period where piglets face several environmental stressors. This transition leads to a significant growth reduction and can result in digestive disorders, including diarrhea. To formulate a feed that meets zinc (Zn) and copper (Cu) requirements during the weaning period while minimizing their release into the environment, it became evident that a more bioavailable micro-mineral supplement is necessary.

Transportation at weaning is an integral component of the American swine industry. However, the long-term effects on growth performance have not been well characterized. Previous research suggests transportation causes weight loss immediately following weaning, but few studies have followed this effect further than 7 d post-weaning, with transport causing decreased body weight in those that have.

Two studies were carried out to investigate the effects of a novel bacterial biosynthetic 6-phytase on growth performance, bone mineralization, and apparent total digestibility (ATTD) of phosphorus (P) in weaned piglets and growing pigs. They were carried out on 192 weaned piglets with initial body weight (BW): 9.3 ± 1.

Tryptophan (Trp) is the rate-limiting substrate for the synthesis of serotonin (5-hydroxytryptamine; 5-HT) in the brain, which plays a central role in the regulation of stress sensitivity and feed intake. The objective of this study was to evaluate the effect of oral Trp supplementation to suckling piglets on 5-HT metabolism, growth performance, and behavior during the suckling (14 to 21 d of age) and nursery (21 to 56 d of age) periods, under social mixing stress at weaning. Eighty 14-day-old suckling piglets from 10 sows (8 piglets per litter) were allotted to 2 treatments.
