Book excerpt: Recent studies indicate that energy intake may limit lean growth in modern improved pig genotypes up to body weights of 80 kilograms and higher. This bulletin discusses the relationship between energy intake & lean growth and the practical implications of the studies for monitoring & manipulating energy intake in pigs. Topics covered include energy intake during the finishing phase, amino acid levels in feed, and the effects of pig genotype on voluntary feed intake.

Download or read book The Suckling and Weaned Piglet written by Chantal Farmer and published by Brill Wageningen Academic. This book was released on 2020 with total page 0 pages. 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 Determining the Lean Growth Curve for Growing-finishing Pigs from the Lysine Requirements Estimated by Using Plasma Urea Nitrogen as a Rapid Response Criterion written by Ruilan Wei and published by . This book was released on 2001 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the lysine requirements obtained in Exp. A and C, the lean growth rates of individually penned PIC barrows were calculated to be 334, 372, 404, 414, 340, 327, and 276 g/d at 33, 52, 69, 72, 87, 93, and 113 kg body weight, respectively. Fitting the data to a polynomial least square regression, a lean growth curve was derived: Y = ( - 0.11606 + 0.04895X - 0.0005855X2 + 0.000001963X3) x 347, where Y was the lean growth rate in grams/day, X was the BW in kilograms. Exp. B determined the lysine requirements of PIC barrows under group penned situation. The results showed that each barrow required 15.8 ± 1.7 and 18.9 ± 1.4 g true ileal digestible lysine/d at 32 and 50 kg body weight, respectively. PUN responses did not allow valid estimates of the lysine requirements for group penned finishing pigs.

Download or read book Feed efficiency in swine written by John F. Patience and published by Springer Science & Business Media. This book was released on 2012-10-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.

Book excerpt: Intense genetic selection for reduced back fat thickness and improved feed utilisation in pigs has resulted in modern genotypes with high lean gain potential, which now deposit a greater amount of lean tissue at faster rates than 20 years ago. As a consequence, to allow pigs to reach their genetic potential for a high capacity of lean tissue gain, higher levels of lysine relative to energy must be fed. The lysine: energy ratio can be largely influenced by genotype, sex, age and health status of the pig. Thus, continues efforts are required to characterise the effects of increasing dietary lysine in evolving modern pig genotypes reared in commercial production environments. The objective of this study was to determine the optimal lysine: energy ratio required for lean growth of a modern pig genotype (PIC337), as well as to determine the growth performance potential under typical commercial conditions. One-hundred-and-eighty PIC337 entire male pigs were used in an experiment with a 2x3 factorial arrangement, including 2 energy levels (2560 kcal NE/kg and 2161 kcal NE/kg) and 3 lysine levels (80%, 100%, 120% of PIC recommendations) in the feed. Thirty-six pens, with 5 pigs per pen, were randomly allocated to 6 treatments (n=6 replicates/treatment). The boars were 9 weeks (63 days) of age at the start of the trial and reared for a period of 17 weeks until slaughter under typical commercial conditions. Average feed intake per pen was measured weekly and all pigs were weighed bi-weekly along with P2 back fat measurements. Average daily feed intake (ADFI), average daily gain (ADG), and feed conversion ratio (FCR) were calculated. The trial continued until 26 weeks (182 days) of age after which all the boars were slaughtered to determine carcass characteristics, including hot carcass weight, cold carcass weight, drip loss %, pH initial, pH ultimate, carcass temperatures as well as back fat thickness. During the grower phase (9 to 18 weeks of age), energy had a significant effect (P 0.05) on body weight gain and FCR, but had no effect (P 0.05) on ADG or ADFI. During the same phase, standardized ileal digestible (SID) lysine had no significant effect (P >0.05) on body weight gain, ADG or ADFI, but had a significant effect (P 0.05) on FCR. Lysine: NE ratio had a significant effect (P

Available in PDF, EPUB and Kindle. Book excerpt: Breed-specific genetic parameters for lean growth rate (LGR) and reproductive traits were estimated for the U.S. Yorkshire, Duroc, Hampshire, and Landrace populations. Parameters were estimated using an animal model by REML method. Estimates of heritabilities were 0.44, 0.44, 0.46, and 0.39 for LGR; 0.10, 0.09, 0.08, and 0.08 for number born alive; 0.08, 0.07, 0.08, and 0.09 for litter weight at 21 d; and 0.05, 0.07, 0.05, and 0.05 for number weaned in the Yorkshire, Duroc, Hampshire, and Landrace breeds, respectively. Most genetic correlation estimates between lean growth and litter traits were small but unfavorable across breeds. Backfat thickness had the largest genetic correlations with number born alive (0.18 to 0.20) and litter weight at 21 d ( -0.27 to -0.30). A four-generation selection experiment was conducted to investigate the effectiveness of selection for LGR and evaluate the correlated responses in litter traits in a synthetic line of pigs based on a Meishan-Yorkshire cross. The estimate of response to selection per generation was 9.6 ± 0.95 g/d for LGR. Correlated responses in litter traits were regressed on generation. The regression coefficients were negative but not significant (P>0.05) for number alive at birth, at 21d, and at 42 d. A significant positive correlated response occurred only for 42-d litter weight (P
