چکیده

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 and 13.1 MJ DE/kg and they consumed 3.61 kg/day.

The Influence of Nutrition on the Reproductive Efficiency of Young Sows

The nutrition of gilts and first-litter sows is discussed in relation to recent research findings. Preliminary data from commercial piggeries suggest that gilts which enter the breeding herd with low fat reserves subsequently have a lower reproductive efficiency . The results of three experiments indicated that first-litter sows required a different feeding strategy during lactation compared to...

Effect of lasalocid on reproductive performance and subsequent lactation in the sow.

The effect of lasalocid (140 mg . head-1 . d-1) on sow reproductive performance and subsequent piglet performance during lactation were examined in a trial that involved 114 sows. Treatments consisted of 1) control diet with no lasalocid during gestation and lactation; 2) lasalocid diet during gestation, control diet during lactation; 3) control diet during gestation and lasalocid diet during l...

Effect of supplemental yeast culture in sow gestation and lactation diets on apparent nutrient digestibilities and reproductive performance through one reproductive cycle.

Ninety-six crossbred sows and gilts were used to study the effect of yeast culture (Diamond V. Mills, Cedar Rapids, IA) on apparent nutrient digestibilities and reproductive performance from d 60 of gestation through d 21 of lactation. Sows were allotted to treatment groups based on parity and BW. Four dietary treatments were made by substituting 0, .5, 1.0, or 2.0% yeast culture for wheat midd...

The addition of ground wheat straw as a fiber source in the gestation diet of sows and the effect on sow and litter performance for three successive parities.

A regional experiment was conducted at 8 experiment stations, with a total of 320 sows initially, to evaluate the efficacy of adding 13.35% ground wheat straw to a corn-soybean meal gestation diet for 3 successive gestation-lactation (reproductive) cycles compared with sows fed a control diet without straw. A total of 708 litters were farrowed over 3 reproductive cycles. The basal gestation die...

EFFECT OF L-CARNITINE FED DURING GESTATION AND LACTATION ON REPRODUCTIVE PERFORMANCE OF TLRI Black Pig No.1 SOWS AND LITTER PERFORMANCE

The purpose of this study was to evaluate the effects of L-carnitine fed during gestation and lactation on reproductive performance of sows and litter performance. A total of 57 multiparous TLRI Black Pig No.1 (TBP) sows were used in this experiment. Pregnant sows were provided daily 150 ppm L-carnitine from day 91 of pregnancy to farrowing and 250 ppm/d L-carnitine provided postfarrowing throu...
