Sow factors affecting voluntary feed intake during lactation
Genetic and environmental changes during the last few decades have resulted in higher milk production and maintenance costs of lactating sows, leading to increased energy requirements, whereas the amount of body fat reserves of, in particular, young immature sows have decreased and voluntary feed intake may have decreased. As a consequence, present voluntary feed intake of sows during lactation...
متن کاملLiver fat content and lipid metabolism in dairy cows during early lactation and during a mid-lactation feed restriction.
During the transition period, the lipid metabolism of dairy cows is markedly affected by energy status. Fatty liver is one of the main health disorders after parturition. The aim of this study was to evaluate the effects of a negative energy balance (NEB) at 2 stages in lactation [NEB at the onset of lactation postpartum (p.p.) and a deliberately induced NEB by feed restriction near 100 d in mi...
متن کاملEffect of source of dietary energy and energy restriction during lactation on sow and litter performance.
The effects of source of energy and energy restriction during lactation on sow and litter performance were investigated in an experiment with 90 primiparous sows. At parturition, the sows were randomly assigned to diets containing either tallow or cornstarch as a major energy source. Energy intake was restricted to 8 Mcal of metabolizable energy X sow-1 X d-1 during a 28-d lactation. All sows r...
متن کاملA Random Regression Analysis of Sow Lactation Feed Intake and the Effect of Temperature on Intake
Lactation feed intake (LFI) has only recently been considered as a possible selection criterion to assist in tackling the issue of sow longevity. It has been postulated that adequate LFI is needed to maintain sow body condition and development and to provide for suckling offspring. Hermesch and Jones (2007) showed that, on average, primiparous sows eating <3.5kg/day during lactation were signif...
متن کاملEffect of fructose consumption during lactation on sow and litter performance and sow plasma constituents.
The effects of dietary consumption of high-fructose corn syrup (HFCS) and dextrose during a 28-d lactation on sow and litter performance and sow plasma constituents were examined in 45 multiparous and 36 primiparous crossbred sows. Isocaloric and isonitrogenous corn-soybean meal diets were formulated to contain either 20% fructose or 20% glucose. Diets were fed on a metabolic BW basis from d 0 ...
