Failure to recycle after weaning, and weaning to oestrus interval in crossbred sows

1979

Failure to recycle after weaning and the interval from weaning to oestrus were studied using sows representing 28 crosses from eight breeds at three stations. Of the sows farrowing their first litter, 12-9 % failed to recycle within 50 days. The least squares mean for weaning to oestrus interval for all crosses was 13-5 days. Hampshire x Landrace, followed by Hampshire x Yorkshire sows had the shortest intervals (8-0 and 8-7 days respectively) whereas Large Black x Lacombe sows had the longest interval (22-1 days). Crosses involving the Yorkshire, Hampshire, Berkshire and Tamworth breeds had shorter intervals than those involving Landrace, Duroc, Large Black and Lacombe. Season of farrowing had significant effect (P < 0-05), with the shortest interval (11-4 days) occurring in autumn and the longest (15-1 days) in spring and summer. Weaning to oestrus interval increased with the increase in litter size. The interval was longer (15-7 days) at Lennoxville but similar at the other stations. There was a steady increase in size in the following litter with the increase in the weaning-oestrus interval. The heritability estimate (full-sib analysis) for the weaning-oestrus interval was 0-25 + 0-10. Repeatability based on limited data was calculated at 0-28.

“…These data suggest that little relationship exists between sow weight loss during lactation and the interval between weaning and first estrus. The results of Brooks et al (1975), Varley and Cole (1978) and Cox et al (1983) support this conclusion. In contrast, Petherick et al (1977) reported an association between lactation weight loss and estrous activity during lactation.…”

“…Research has shown that increasing nutrient intake during the weaning to service interval can reduce the days to oestrus (Brooks et al, 1975). In this study, supplementing the LND diet with Rovabio R Excel increased energy intake during the weaning to service interval.…”

A total of 200 (Large White 3 Landrace) sows were used in a 39-day study to evaluate the effects of feeding a non-starch polysaccharide (NSP)-hydrolysing enzyme multicomplex (Rovabio R Excel) in conjunction with a high-or reduced nutrient-density diet during lactation on sow body condition, feed intake and progeny performance. Eight sows were selected each week for 25 weeks, blocked by parity and BW into groups of four, and within the block randomly assigned to one of the four treatments (n 5 50/treatment). Treatments were: (1) LND: low energy (13.14 MJ of DE/kg), low CP (15%) diet; (2) LND 1 RE: LND with 50 mg/kg NSP-hydrolysing enzyme; (3) HND: high energy (14.5 MJ of DE/kg), high CP (16.5%) diet; and (4) HND 1 RE: HND with 50 mg/kg NSP-hydrolysing enzyme. Sows were fed treatment diets from day 109 of gestation until the day of subsequent service. Between weaning and re-service, Rovabio R Excel addition to LND diets resulted in an increase in energy intake; however, a reduction was observed when supplemented to the HND diet (P , 0.05). The inclusion of Rovabio R Excel increased feed and energy intake during week 3 (days 15 to 21) of lactation (P , 0.05). Sows fed diets supplemented with Rovabio R Excel had greater back-fat depth at weaning and service (P , 0.05); however, the magnitude of change in back-fat depth during lactation and from farrowing to service was not different between treatments. Feeding the HND diet increased energy intake before farrowing, throughout lactation and during the weaning to service interval (P , 0.01); however, overall, average daily feed intake tended to be reduced (P , 0.10). At service, sows fed the HND diet were heavier than sows fed the LND diet (P , 0.05); however, the magnitude of change in BW between treatments was not different. Feeding the HND diet to sows resulted in a tendency for heavier piglets at birth (P 5 0.10) that tended to grow at a faster rate and be heavier at weaning than piglets from sows fed the LND diet (P 5 0.06). These results indicate that NSP-degrading enzymes offer minimal benefit to sows and their progeny when fed before and during lactation; however, increasing energy intake of sows during lactation may beneficially affect progeny.
