Gestating sows are often fed a single diet throughout their gestation cycle, leading to situations of nutrients deficiency or excess at the individual level. The purpose of this study was to characterize, over 3 consecutive cycles, the impact of a precision feeding (PF), i.e., dietary supplies adjusted at individual level in terms of quantity (ener...

The dairy industry stands at the intersection of two critical global challenges: the need to meet rising demands for high-quality dairy products and the imperative to reduce its environmental impact. This study’s primary aim is to bridge the historical-to-modern gap in dairy cattle management practices and to provide a comprehensive perspective tha...

Precision feeding, a practice involving customized diets tailored to individual nutritional requirements, has emerged as a promising paradigm within animal production, underpinned by advanced technologies and data analytics. This mini review embarks on an exploration of the evolutionary trajectory of precision feeding and its profound ramifications...

Simple Summary Pigs reared in tropical climate areas are frequently exposed to high ambient temperatures. The increase in ambient temperature above thermoneutrality evokes behavioral changes that alter the feeding pattern of pigs, triggering a reduction in performance. In addition, the light program may also modulate the feeding behavior of pigs. T...
More frequent harvesting of grass swards provides an opportunity to improve the nutritive value of grass silage. This study investigated the effect of offering silages produced within either a three- (3H) or four-harvest (4H) system on dairy cow performance when concentrate supplements were offered according to the individual cow’s milk yield (feed...

New technologies, such as sensors and automatons, are being developed in agriculture to reduce workload or help farmers make management decisions. The most common approach to the analysis of the huge amount of data generated by these technologies is to use machine-learning algorithms, to detect health or welfare problems for example. The hypothesis...

Room temperature affects gestating sows’ activity and social behaviors, which also impact their energy requirements. Daily temperature and individual activity are relevant information to take into account into the nutritional models.

Dietary energy and nutrient losses associated with its conversion into animal products increase production costs and contribute to the environmental footprint of farms with the excessive application of nitrogen, phosphorus, or trace minerals from manure or carbon and methane losses. Formulating diets with the appropriate levels of minerals and amin...

In lactating sows, nutrient requirements among individual animals vary greatly. With a single diet, lactating sows are likely to be either underfed, which results in body reserve mobilization, or overfed, which results in nutrient excretion. Precision feeding (PF) is a new feeding strategy that aims to provide the right amount of nutrients at the r...

Nutritional requirements of heavy immunocastrated (IM) pigs and therefore appropriate feeding strategies have not yet been determined. Thus, the effects of changes in dietary net energy (NE) content were studied in 41 IM pigs, fed ad libitum diets with low, medium, and high NE content (LNE, MNE, and HNE diets, with 8.5, 9.3, and 10.0 MJ NE/kg, resp...
