Influence of lactation length and feed intake on reproductive performance and blood concentrations of glucose, insulin and luteinizing hormone in primiparous sows
Twenty-four pregnant gilts were assigned to four experimental treatments in a 2×2 factorial arrangement. The first factor was lactation length (12 vs. 21 days) (LL); the second factor was a provided amount of diet (FF, full feeding vs. low, 2 kg/day). The same diet (1% lysine and 3.27 Mcal ME/kg) wa...

| description | Twenty-four pregnant gilts were assigned to four experimental treatments in a 2×2 factorial arrangement. The first factor was lactation length (12 vs. 21 days) (LL); the second factor was a provided amount of diet (FF, full feeding vs. low, 2 kg/day). The same diet (1% lysine and 3.27 Mcal ME/kg) was used from farrowing to 1 day after weaning. Sow body weight, backfat thickness (BF), litter weights, and blood samples were measured prior to and 1 day after weaning. Sows were monitored for estrous once daily in the presence of a boar until 35 days after weaning or until estrous was detected. Average feed intake during lactation (ADFI) was 1.9 (low) and 4.0 (FF) kg/day. ADFI among individual sows varied from 1.8 to 4.9 kg/day. Positive effects of both LL and feed intake treatments were found (

P<0.05) on sow body weight loss, backfat loss, glucose concentrations, mean luteinizing hormone (LH) concentrations, and LH pulse frequency prior to weaning, and farrowing-to-estrous interval. Greater concentrations of insulin prior to weaning were associated only with feed intake treatment (
P<0.05). No interactions between LL and feed intake treatments were found in any measures except for sow body weight loss. Using regression analysis, greater lactation feed intake was associated with greater concentrations of insulin and glucose, greater LH pulse frequency prior to weaning and shorter farrowing-to-estrous interval in both LL treatments. We suggest that greater feed intake during lactation improves farrowing-to-estrous interval through LH release regardless of LL treatment.</description><identifier>ISSN: 0378-4320</identifier><identifier>EISSN: 1873-2232</identifier><identifier>DOI: 10.1016/S0378-4320(98)00093-1</identifier><identifier>PMID: 9776488</identifier><language>eng</language><publisher>Netherlands: Elsevier B.V</publisher><subject>Animals ; Blood Glucose - metabolism ; CERDAS ; CICLO ESTRAL ; CYCLE OESTRAL ; DURACION DE LA LACTANCIA ; DUREE DE LA LACTATION ; Eating ; Estrus ; FEED INTAKE ; Female ; GLUCOSA ; GLUCOSE ; INGESTION DE PIENSOS ; INSULIN ; Insulin - blood ; INSULINA ; INSULINE ; Lactation - physiology ; LACTATION DURATION ; Luteinizing Hormone - blood ; Male ; Nutrition ; OESTROUS CYCLE ; Parity ; PARTO ; PARTURITION ; PERFORMANCE DE REPRODUCTION ; Postpartum ; Pregnancy ; PRISE ALIMENTAIRE (ANIMAUX) ; Reproduction - physiology ; REPRODUCTIVE PERFORMANCE ; REPRODUCTIVIDAD ; Sow ; SOWS ; Swine - physiology ; Time Factors ; TRUIE</subject><ispartof>Animal reproduction science, 1998-08, Vol.52 (2), p.153-163</ispartof><rights>1998 Elsevier Science B.V.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c448t-11ed9bf7a717f701de3f0909936dc145b3774ca9f216333203a7a1ff137284393</citedby><cites>FETCH-LOGICAL-c448t-11ed9bf7a717f701de3f0909936dc145b3774ca9f216333203a7a1ff137284393</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0378432098000931$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65306</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/9776488$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Koketsu, Yuzo</creatorcontrib><creatorcontrib>Dial, Gary D.</creatorcontrib><creatorcontrib>Pettigrew, James E.</creatorcontrib><creatorcontrib>Xue, JinLiang</creatorcontrib><creatorcontrib>Yang, Hong</creatorcontrib><creatorcontrib>Lucia, Thomaz</creatorcontrib><title>Influence of lactation length and feed intake on reproductive performance and blood concentrations of glucose, insulin and luteinizing hormone in primiparous sows</title><title>Animal reproduction science</title><addtitle>Anim Reprod Sci</addtitle><description>Twenty-four pregnant gilts were assigned to four experimental treatments in a 2×2 factorial arrangement.
