Book excerpt: 'Weaning the Pig: Concepts and Consequences' is a new book that addresses the major issues surrounding the weaning process, both for piglets and the breeding herd, in modern-day pig production. The post-weaned pig presents many challenges to the manager, stockperson and nutritionist, and as such is a critical phase in the overall production system. Numerous challenges are also faced by the sow, which is required to be rebred as soon as possible after weaning. This book draws together summaries of research dealing with both piglets and the sow, and is a unique book in this regard. Accordingly, the material presented covers in detail the following areas associated with the weaning process: growth of the weaned pig, nutritional management in preparation for weaning, behavioural changes and adaptations around weaning, voluntary feed intake, digestive physiology, modulation of small intestinal integrity, the intestinal microflora and diarrhoeal diseases after weaning, intestinal immunity, nutritional requirements and intestinal requirements of the weaned pig, environmental and housing issues after weaning, saving and rearing supernumery and underprivileged piglets, and productivity and longevity of the weaned sow. The chapters have been written by acknowledged experts from around the world. The book is an ideal reference for all professions associated with the pig industry, and is invaluable as a text for students at both undergraduate and postgraduate levels.
Download or read book Effect of Milk Supplementation During Lactation on Pre and Post weaning Sow and Piglet Performance on a Commercial Farm written by Brent William Ratliff and published by . This book was released on 2005 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to evaluate the effect of supplemental milk during lactation on sow and piglet performance. Sows were grouped according to parity as follows: Parity 1 = group 1, Parities 2 and 3 = group 2, and all Parities greater than 3 = group 3. Litters from sows within the same group were randomly allotted to either milk or no milk treatments. At 48 h post parturition, milk supplementation was initiated and piglets were counted and weighed. At day 14 to 18, each litter was weighed, counted, and weaned. In Exp. 2 piglets were transferred to a nursery facility following weaning. Supplemental milk improved piglet weight gain and survivability pre-weaning. Also, sows with piglets receiving supplemental milk returned to estrus in fewer days. The greatest response with milk supplementation was observed in sows greater than parity three. Nursery growth performance was similar in both treatments, however piglets receiving supplemental milk pre-weaning had improved survivability.

This book was released on 2006 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to: (1) quantify the effect of piglet birth weight on weaning and nursery off-test weights, (2) assess the effect of weaning age on nursery pig performance, and (3) model the effect of weaning age on subsequent sow reproductive performance. The study utilized Danbred N.A. (Columbus, NE) barrows and gilts (n=2,467) from a commercial maternal line multiplication herd. Litters were randomly assigned at birth to either a 15 d (pigs weaned at 14, 15, and 16 d of age) or a 20 d (pigs weaned at 19, 20, and 21 d of age) average weaning age group. Increasing birth weight from 0.94 to 2.06 kg improved subsequent growth performance. Collectively, birth weight and weaning weight are important predictors of subsequent nursery growth performance. The research also defined how weaning age affects ADG, ADFI, mortality %, G:F, and feed cost/kg gain in the nursery phase of production. Pigs weaned at 20 d had greater ADG, increased ADFI, fewer pigs removed from the test, similar G:F ratios, and lower feed cost/kg gain when compared to pigs weaned at 15 d. Pigs in the 20 d weaning age group were also heavier at the end of the 42 d nursery phase of production when compared to pigs weaned in the 15 d group. Based on the differences seen in pigs weaned at 20 d and 15 d, weaning pigs at 20 d may prove advantageous in commercial operations because of the improvements in nursery growth performance. The research also analyzed the effect of lactation length on wean-to-estrus interval (WSI), wean-to-conception interval (WCI), and subsequent litter size in sows weaned at two different average weaning ages. No significant lactation length treatment differences were observed for WSI, WCI, or subsequent litter size. This study indicates that producers should be able to choose weaning ages in the range of 15 to 20 d without any negative impacts on sow reproductive performance. Thus, when producers are making weaning age decisions they must consider what the best decision is for the entire production system.

Available in PDF, EPUB and Kindle. Book excerpt: The last books discussing the neonatal or weaned pig were published over 15 years ago. This new book provides up to date information on the suckling and weaned piglet. It covers novel and important topics such as microbiota development in piglets and management of hyperprolific litters. It also discusses topics such as weaning age and its long term influence on piglet heath and performance. The developments of lean and fat tissues and of the intestinal immune system in young pigs are described in detail. Emphasis is put on well-being with chapters focussing on husbandry interventions in suckling piglets as well as consequences of the lactational environment on behavioural disturbances of pigs after weaning. The multiple stressors encountered at and post-weaning are also discussed. Updates on essential subjects such as neonatal mortality, creep feeding of suckling piglets, feeding strategies for weaned pigs, housing systems post-weaning and diseases of piglets are provided. The information covered in this book should be of great assistance to animal scientists, nutritionists, veterinarians and swine producers. They will be made aware of most recent knowledge that will assist in improving the performance and welfare of suckling and weaned piglets.

Download or read book The gestating and lactating sow written by Chantal Farmer and published by BRILL. This book was released on 2023-09-04 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last book on the lactating sow was published over 15 years ago. This new book brings us up to date in current knowledge on the gestating and lactating sow. It covers new and important topics such as conditioning of gilts for optimal reproductive performance, feeding high fibre diets to gestating sows and providing various fat sources in gestation and lactation. It also describes the several key success factors to group-housing systems in gestation, which is a must due to the current move towards group-housing. The new concept of transition feeding for sows is discussed, as well as the factors involved in mammary development of gilts and sows, both of which are instrumental for maximum colostrum and/or milk yields. The impact of the human-animal interactions on sow welfare and performance is discussed with focus on new handling practices that could be developed to overbalance the negative interactions inherent to pig management systems. Updates on must-have topics, such as amino acid and energy requirements of sows, colostrum and milk yield and composition, and sow health are also provided. The subjects covered in this book will assist animal scientists, nutritionists, veterinarians and swine producers in learning the most recent information on relevant and current topics affecting sow production, and in knowing which areas are in need of further research efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Welfare of pigs has become a larger issue in the United States in recent years. The evolution of production facilities and production schemes require investigation into the performance of sows and piglets. Especially given public perception and changing regulations regarding food production. The use of technology as a strategy to decrease preweaning mortality may have detrimental effects on the sows and should be explored. Fifty-six sows treated with wearable novel technology to reduce preweaning mortality showed more exaggerated behavioral response to a simulated piglet crushing event by jumping or rising to a standing position more than control sows (P 0.01). Sows treated with novel technology did not, however, show any greater physiological response to treatment than control sows (P 0.10). Piglet birth order and management status (transferred or not) as well as sow treatment in lactation impact future piglet performance and welfare. The application of aversive stimuli to sows disrupted nursing stability. More piglets in VIB+EI treatment missed nursing bouts over the course of treatment (P=0.001). Birth order was grouped into categories (piglets born 1-5, 6-11, 12-18, 19-21) and transferred piglets. Earlier born piglets had a shorter latency to suckle (P = 0.05). Piglets that were transferred were more likely to move toward the sows head to suckle (P = 0.09). Transfer piglets and piglets in birth category three were less consistently in the same teat quadrant (P = 0.05) compared to earlier or late born piglets. Piglet weight was taken at birth, day seven and weaning. Transfer piglets were largest throughout, and latest born piglets gained a higher percentage of body weight over the course of lactation (P

Download or read book Evaluating Nutritional Strategies in the Sow Transition Period to Improve Sow and Litter Performance Colostrum Yield and Piglet Survivability written by Kiah Marie Gourley and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments using a total of 1,325 sows were used to determine the impact of different sow feeding strategies on sow and litter performance. Experiment 1 determined the optimal soybean meal concentration in lactating sow diets using three levels of increasing dietary soybean meal (25, 30, or 35% of total diet). Increasing soybean meal concentration increased sow BW loss and tended to increase sow backfat loss from farrowing to weaning. Sow average daily feed intake (ADFI) decreased linearly as soybean meal concentration increased. Despite the linear response in ADFI, the greatest decrease was observed as soybean meal concentration increased from 30 to 35% of the diet. There was no evidence for difference in wean to estrus interval, or litter performance between dietary treatments. Sow serum urea nitrogen concentrations taken on d 14 of lactation increased as soybean meal concentration increased. Experiment 2 evaluated the duration of feeding increased Lys and energy prior to farrowing on sow and litter performance, piglet survival and colostrum quality in a commercial sow farm. Sows were fed 1 of 3 dietary regimens starting on d 107 of gestation: 1) Control: 2.0 kg/d gestation feed (12.5 g SID Lys and 6.5 Mcal ME) until d 113 of gestation, then 2.7 kg/d lactation feed (28 g SID Lys and 9.4 Mcal ME) until parturition; 2) 2.0 kg/d gestation feed (12.5 g SID Lys and 6.5 Mcal ME) until d 113 of gestation, then 3.8 kg/d lactation feed (40 g SID Lys and 13.3 Mcal ME) until parturition; or 3) 3.8 kg/d lactation feed (40 g SID Lys and 13.3 Mcal ME) until parturition. Increasing the duration of feeding additional Lys and ME increased sow weight and backfat gain from d 106 to 113. Average total born and born alive piglet birth weight (BiWt) was greater in gilts fed 3.8 kg/d lactation diet starting on d 107 or 113 vs. control, with no difference in piglet BiWt in sows or weaning weight in gilts and sows. Piglet mortality after cross-foster to weaning was decreased in sows fed 3.8 kg/d lactation diet starting on d 113 vs. control or increased lactation diet starting on d 107, but not in gilts. Litter gain from cross-foster to weaning was decreased in gilts fed 3.8 kg/d lactation diet starting on d 107 compared to control, with no evidence for difference in sows. Colostrum immunoglobulin G was increased in gilts and sows fed 3.8 kg/d of the lactation diet starting on d 113 compared to control. There was no evidence dietary regimen influenced piglet colostrum intake or colostrum yield, or subsequent reproductive performance. Experiment 3 evaluated the effects of timing and size of meals before farrowing on sow and litter performance under commercial conditions. Sows were fed 1 of 3 feeding management strategies until farrowing: 1) 2.7 kg lactation diet (1.15% standardized ileal digestible lysine and 2,153 Kcal/kg net energy) once daily at 0700 h; 2) 4 daily meals of 0.67 kg (0100 h, 0700 h, 1300 h, 1900 h); 3) ad libitum lactation diet and encouraged to consume feed at 0100 h, 0700 h, 1300 h, and 1900 h. Feeding sows ad libitum before farrowing tended to reduce sow body weight loss and reduce backfat loss from entry into the farrowing house until weaning compared to sows fed 4 daily meals, with sows fed once daily intermediate. Litter gain from 24 h to weaning tended to be greater in sows fed ad libitum or 4 times daily prior to farrowing compared to sows fed one meal. Piglet weaning weight increased in sows fed ad libitum before farrowing, compared to those fed one meal, with those fed 4 times daily intermediate. There was no evidence for difference in farrowing duration, stillborn rate, colostrum yield, or 24 h piglet survival regardless of treatment. However, from 24 h after farrowing to weaning, sows fed one daily meal prior to farrowing had an increased percentage of fall-behind pigs compared to sows fed ad libitum, and increased preweaning mortality compared to sows fed four daily meals, resulting in reduced weaned percentage compared to sows fed four daily meals. There was no difference in subsequent reproductive performance regardless of treatment.
