“…As expected, sows in the current study lost body weight from late gestation through post-weaning, and parity 1 dams weighed less and lost more body weight during lactation than parity 2 dams. Others (Shurson et al, 1986;Probert et al, 1999) have also reported similar reductions in body weight during lactation between primiparous and multiparous dams. Negative energy balance during lactation has been linked to delayed weaning-to-estrus interval (Svajgr et al, 1972;Reese et al, 1984;Baidoo et al, 1992;Zak et al, 1998).…”

“…Unsurprisingly, therefore, piglets born to E sows were heavier throughout the pre-weaning period, since they were heavier at birth. In contrast, much of the literature reports increased growth rates in the offspring of fat supplemented animals (among others Shurson et al, 1986;Wladyslaw, 1991;Rooke et al, 2000;Averette-Gatlin et al, 2002). Caution needs to be exercised in comparing the results of different studies due to differences in the timing of supplementation and age of piglets at weaning.…”

This study aimed to determine the consequences of altering the fatty acid profile of sow diets during mid-to-late gestation; oils of different fatty acid composition were chosen as energy supplements to provide diets with different fatty acid profiles. Forty-eight multiparous sows were used to evaluate the effects of fat supplementation from day 60 of gestation until parturition. Sows were allocated to either 3 kg/day of commercial sow pellets (control; C) or an experimental diet consisting of 3 kg/day of commercial sow pellets supplemented with 10% extra energy in the form of excess pellets (E), palm oil (P), olive oil (O), sunflower oil (S) or fish oil (F). From days 0 to 60 of gestation, all sows were given 3 kg/day of sow pellets as for the C group. The E diet resulted in the heaviest piglets at birth whereas the offspring of O and S sows were the lightest at birth. The offspring of S sows remained lighter throughout the pre-weaning period, and were also the leanest by 14 days of age. In contrast, pigs born to S sows possessed more fat by the time they reached commercial end point (E140 days of age). In conclusion, altering the fatty acid profile of the sow diet during the second half of gestation has long-term consequences for the development of their offspring.

“…Em Shurson et al (1986) pôde ser observado que os maiores valores encontrados para produção de leite foram para as fêmeas tratadas com uma alimentação contendo 10% de gordura, com o valor médio de 7,68 Kg/dia, estando esse valor abaixo das médias encontradas em nossa experimentação. Ainda em relação a gordura foi encontrado no trabalho de Boyd, et al (1982), com utilização de gordura animal na alimentação, valor similar (9,44 kg/dia), aos apresentados no presente estudo.…”
