“…Almost 100% of Pre-C piglets had sampled creep feed at weaning, which is higher than previously reported [e.g., ± 34% ( 56 ), ± 48% ( 57 ), ± 70% ( 28 ) at weaning on d28]. The relatively high percentage of eaters per litter can be a function of multiple factors that were previously found to affect (creep) feed intake, such as large pen size ( 58 ), numerous feeding spaces ( 59 – 61 ), early feed provisioning ( 62 ), higher weaning age ( 63 ), and/or creep feed composition ( 63 – 65 ). The large amount of time spent eating of Pre-C piglets may have abated any beneficial effects of larvae provisioning.…”

Weaning is a stressful event for piglets, involving substantial changes to their nutritional and social environment. Providing edible enrichment around weaning may ease the weaning transition by increasing pre-weaning feed intake and improving post-weaning performance, health, behavior, and affective state. In this study, we investigated the effects of providing live black soldier fly larvae (BSFL) as edible enrichment pre- and/or post-weaning. Pre-weaning, piglets received either only creep feed (Pre-C, n = 14 litters) or creep feed and live BSFL (Pre-L, n = 15 litters) ad libitum, and post-weaning piglets either had no access to live BSFL (Post-C, n = 24 pens) or they could rotate tubes that released BSFL (Post-L, n = 24 pens) at levels up to 20% of their expected daily dry matter intake, resulting in treatments CC, CL, LC, and LL. No interaction between pre- and post-weaning treatment was found for any of the measured parameters. Before weaning, Pre-L piglets preferred to interact with larvae over creep feed, and Pre-C piglets interacted more with creep feed than Pre-L piglets. Total time spent on feed-directed behaviors did not differ. Continuous larvae provisioning increased caecum length and proximal stomach digesta pH, while it decreased the passage of glucose and fluorescein isothiocyanate through the colon wall on d3 post-weaning (CC vs. LL, n = 12 piglets/treatment). Post-weaning diarrhea and final body weight were not affected by treatment. After weaning, Pre-C piglets tended to eat more and grew marginally faster than Pre-L piglets. Post-C piglets spent more time eating and had a higher feed intake post-weaning than Post-L piglets. Based on home-pen behavioral observations, Post-L piglets actively explored and ate the larvae. Post-C piglets spent more time on exploring the environment and nosing pen mates, and they spent more time on manipulating pen mates on d8 and played more on d8 & 15 compared to Post-L piglets. Piglet responses to a novel environment and an attention bias test on d4 & 5 post-weaning were not influenced by larvae provisioning. In conclusion, pre-weaning larvae provisioning did not improve pre-weaning feed intake and post-weaning performance, however post-weaning larvae provisioning did benefit piglet behavior as less manipulation of pen mates was observed.

“…28 Likewise, decreasing the number of pigs per feeder hole (approximately 3.75 pigs), particularly at high stocking densities (15 pigs/pen) or low floor space allowance (≤ 0.25 m 2 ), has been shown to result in more rapid onset of feeding and reduced removals. 29,30 The most important factor of feeder design is ease of feed access and management. Typically, wet/dry feeding systems are not recommended because newly weaned pigs have a difficult time dispensing feed and often overfill the feed pan with water.…”

Preweaning strategies to minimize fallback pigs in the nursery include cross fostering, creep feeding, and weaning an older pig. Postweaning strategies to minimize fallback pigs in the nursery include optimum barn temperature and ventilation set points, easy access to feed and water, and proactive placement strategies. Phase-feeding programs to match the nutrient requirements and digestive abilities of weaned pigs are also crucial. Managing fallback pigs can be accomplished by minimizing drafts in removal pens, providing supplemental heat sources, having multiple feed access points by providing gruel and mat feed, and ensuring more intensive observations of pigs in removal pens.

“…Essa mudança é um fator estressante e pode refletir nos índices zootécnicos da leitegada. Frente a isso, a escolha do tipo de comedouro, ou até mesmo acessórios de comedouros, podem ser importantes nesta fase (6,7). Pois os animais apresentam rápido ganho de peso neste período e a alimentação em quantidades insuficientes podem gerar animais refugo, indesejados neste tipo de sistema.…”

A bandeja economizadora de ração é um acessório disponível no mercado, deve ser acoplado em comedouros para suínos com o objetivo de reduzir o desperdício de ração pelos animais. Entretanto pouco se conhece sobre os reais benefícios deste acessório no desempenho de leitões na fase de creche. Com isso, o objetivo deste estudo foi verificar a influência da bandeja economizadora de ração no desempenho zootécnico de leitões na fase de creche. Para isso, foram dispostos um comedouro circular com a bandeja economizadora acoplada (Tratamento 1) e um comedouro retangular (Tratamento 2) em duas baias. Em dois lotes de leitões desmamados aos 28 dias foram medidos o consumo de ração, ganho de peso, ganho de peso médio diário e a conversão alimentar. Os dados obtidos não apresentaram diferença estatística entre os tratamentos. Em conclusão, a bandeja economizadora de ração não influenciou o desempenho zootécnico de leitões na fase de creche.
