The Effect of Diet during Lactation on the Reproductive Performance of First-litter Sows
Eighty first-litter sows in a commercial piggery were assigned to two feeding treatments during a 26-day lactation. A commercial diet containing an estimated 15% crude protein (CP), 0.65% lysine and 12.5 MJ digestible energy (DE)/kg was offered to sows in the control group which consumed 3.04 kg/day. Sows in the treatment group were given a higher quality diet containing 16.4% CP, 0.83% lysine ...

متن کاملEffect of rapeseed meal supplementation to gestation diet on reproductive performance, blood profiles and milk composition of sows
OBJECTIVE This experiment evaluated the effect of dietary supplementation levels of rapeseed meal (RSM) in gestation diets on reproductive performance, blood profiles, milk composition of sows, and growth of their progeny. METHODS A total of 55 mixed-parity sows (Yorkshire×Landrace; average parity = 3.82) with an initial body weight (BW) of 193.0 kg were used in this experiment. Sows were all...
متن کاملA regional evaluation of injections of high levels of vitamin A on reproductive performance of sows.
A regional study involving 443 litters from 182 sows was conducted at 5 cooperating experiment stations to determine the effects of an i.m. injection of vitamin A at weaning and breeding on subsequent litter size of sows. Sows were assigned to 1 of 3 treatments given at weaning and again at breeding: 1) a placebo i.m. injection (2 mL of corn oil), 2) i.m. injection with 250,000 IU of vitamin A ...
متن کاملRepopulation Method for Improvment of Reproductive Performance of Sows
The experiment was designed to evaluate differences in reproductive performance parametres in sows of selected utilitarian breeds before and after repopulation. The experimental population consisted of 160 sows, while the group before repopulation counted 80 sows from 1 to 5 litter. The repopulated (newly brought) group counted 80 gilts at the 1 litter. The values of the total number of piglets...
