Effects of Saccharomyces cerevisiae var. boulardii CNCM I-1079 on performance, colostrum and milk composition, and litter performance of mixed-parity sows in a tropical humid climate. Trop Anim Health Prod 2022; 54:41. [PMID: 35013815 DOI: 10.1007/s11250-022-03051-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 01/04/2022] [Indexed: 02/07/2023]
Abstract
This study aimed to evaluate the effects of Saccharomyces cerevisiae var. boulardii (SB) for sows on their productive performance, colostrum and milk composition, and litter performance, in tropical humid climatic conditions. A total of 105 sows (Topigs Norsvin®) were allotted to a 5 × 3 completely randomized factorial design, with five diets (control diet; SBGL4 and SBGL8: 0.04 and 0.08% SB supplementation from the 90th day of gestation until 24th day of lactation; SBL4 and SBL8: 0.04 and 0.08% SB supplementation during lactation) and three parity order groups (PO: 1st and 2nd; 3rd and 4th; 5th to 7th), considering each sow and their litter as experimental unit. Sows above the 5th PO that fed control diet had a lower daily milk production (DMP), number of weaned piglets (NWP), and daily weight gain of litter (DWGL) than sows from 1st to 4th PO that fed the same diet (P < 0.05). Dietary supply of SBGL4 and SBGL8 to older sows provided a higher DMP, NWP, and DWGL when compared to sows of same PO that fed the control diet (P < 0.05). Dietary supply of SBGL4, SBGL8, SBL4, and SBL8 provided a higher dry matter and protein contents in sows' milk of 1st and 2nd PO when compared to sows from same PO that fed control diet (P < 0.05). Dietary supply of SB enhances milk yield of older sows and their litter performance, as well as the dry matter and protein content of younger sows' milk in tropical humid climatic conditions.

Mendoza SM, Boyd RD, Remus J, Wilcock P, Martinez GE, van Heugten E. Sow performance in response to natural betaine fed during lactation and post-weaning during summer and non-summer months. J Anim Sci Biotechnol 2020; 11:69. [PMID: 32626576 PMCID: PMC7330960 DOI: 10.1186/s40104-020-00471-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Accepted: 05/11/2020] [Indexed: 01/07/2023] Open
Abstract
Background Two studies were conducted to evaluate the effects of dietary natural betaine on sow reproductive performance during summer (Exp. 1) and non-summer months (Exp. 2). Treatments were designed as a 2 × 2 factorial arrangement with factors including dietary betaine (0 or 0.2%) and period of supplementation (lactation or post-weaning until 35 days post-insemination). In Exp. 1, 322 and 327 sows and in Exp. 2, 300 and 327 sows representing young (parity 1 and 2) and mature (parity 3 to 6) sows, respectively, were used. Results In Exp. 1, supplementation of betaine during lactation increased sow body weight losses (− 11.95 vs. −14.63 kg; P = 0.024), reduced feed intake (4.12 vs. 4.28 kg/d; P = 0.052), and tended to reduce percentage of no-value pigs (P = 0.071). Betaine fed post-weaning reduced weaning-to-estrus interval (5.75 vs. 6.68 days; P = 0.054) and farrowing rate (86.74% vs. 91.36%; P = 0.060), regardless of parity group. Post-hoc analysis with sows clustered into 3 parity groups (1, 2 and 3, and 4+) indicated that betaine fed in lactation to parity 4+ sows (P = 0.026) and betaine fed post-weaning to parity 1 sows increased the number of pigs born in the subsequent cycle (P ≤ 0.05). In Exp. 2, betaine fed during lactation tended to reduce the weaning-to-estrus interval (6.64 vs. 7.50 days; P = 0.077) and farrowing rate (88.23% vs. 83.54%; P = 0.089), regardless of parity group. Feeding betaine post-weaning reduced number of pigs born (13.00 vs. 13.64; P = 0.04) and pigs born alive (12.30 vs. 12.82; P = 0.075), regardless of parity group. Conclusions Using 0.2% betaine during the non-summer months did not benefit sow performance. During the summer, betaine supplementation in lactation increased subsequent litter size in parity 4+ sows. Betaine fed during the post-weaning period reduced the wean-to-estrus interval and farrowing rate, increased total number of pigs born for parity 1 sows and reduced total number of pigs born to parity 4+ sows. Further research is needed to determine if the detrimental effects on feed intake and farrowing rate may be correlated and depend on dietary betaine level.

Effect of maternal or post-weaning methyl donor supplementation on growth performance, carcass traits, and meat quality of pig offspring. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2019; 99:2096-2107. [PMID: 30298675 DOI: 10.1002/jsfa.9402] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Revised: 08/31/2018] [Accepted: 10/02/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND Limited studies have examined links between maternal methyl donor (MET) supplementation and the growth-development characteristics of offspring, and possible underlying mechanisms for such links. This study investigated the effect of maternal or post-weaning MET-supplementation on growth performance, carcass characteristics, and meat quality of the finishing (d 180) offspring. Twenty-four sows were placed on a control (C) or MET-supplemented diet during pregnancy and lactation. Forty-eight female offspring were fed the control or MET-supplemented diet from weaning to 6 months of age, resulting in four study groups (six litters per group): C/C, C/MET, MET/C, and MET/MET. RESULTS Maternal MET-supplementation increased average daily gain (ADG), body weight (BW), lean percentage and longissimus dorsi (LD) of the offspring at day 180 (P < 0.05), and upregulated the myosin heavy chain IIx, myogenic differentiation and muscle regulatory factor 4 mRNA levels in the LD muscle (P < 0.05). Meanwhile, offspring from maternal MET-supplementation exhibited a higher pH24h post mortem and superoxide dismutase activity, a lower L* 45min , glycolytic potential, malonaldehyde content in the LD muscle, and plasma homocysteine concentration (P < 0.05). CONCLUSION Maternal MET-supplementation has a remarkable effect on growth performance, carcass traits, and meat quality of the offspring, which is associated with increased expression levels of myogenic genes and anti-oxidant capacity. © 2018 Society of Chemical Industry.

Johnson JS. Heat stress: impact on livestock well-being and productivity and mitigation strategies to alleviate the negative effects. ANIMAL PRODUCTION SCIENCE 2018.

Abstract
Heat stress (HS) is a multi-factorial problem that negatively affects livestock health and productivity and is closely linked with animal welfare. While HS may not be harmful when animals are able to adapt, the physiological changes that occur to ensure survival may impede the efficient conversion of feed energy into animal products. This adaptive response can be variable and is often based on previous HS exposure, genetics, species and production stage. When the heat load becomes too great for adaptive responses to compensate, the subsequent strain response causes reduced productivity and well-being and, in severe cases, mortality. The effects of HS on livestock productivity are well documented and range from decreased feed intake and body weight gain, to reduced reproductive efficiency and altered carcass composition and meat quality. In addition, researchers are beginning to elucidate the effects of prenatal HS on postnatal livestock performance and welfare. As knowledge of the negative impacts of HS on livestock performance and welfare increases, so will the development of effective mitigation strategies to support maintenance of productivity during times of high thermal heat loads and preserve appropriate animal welfare standards.
