The effect of corn silage particle size and cottonseed hulls on cows in early lactation.
The objective of this study was to evaluate the effects of reducing forage particle length (FPL) and the inclusion of cottonseed hulls (CSH) on intake, digestibility, chewing activity, and milk production of cows in early lactation. Sixteen multiparous cows averaging 17 +/- 3 d in milk and 677 +/- 58 kg BW were assigned to one of four 4 x 4 Latin squares. One square contained ruminally cannulat...
متن کاملEfficacy of sucrose and milk chocolate product or dried porcine solubles to increase feed intake and improve performance of lactating sows.
Two experiments were conducted to determine the voluntary feed intake and performance of lactating sows fed diets containing a sucrose/milk chocolate product (MCP) blend (Exp. 1) or dried porcine solubles (DPS; Exp. 2). Dried porcine solubles is a coproduct of heparin extraction from porcine small intestines. In Exp. 1, mixed-parity sows (n = 108) at two research centers were assigned to a corn...
متن کاملEffect of Season, Parity and Lactation on Reproductive Performance of Sows in a Tropical Humid Climate
The aim of this study was to analyze post-weaning reproductive performance of Large White sows in relation to season, parity and their lactation performance under tropical conditions in Guadeloupe (French West Indies, 16° Lat. N, 61° Long. W.). This work was based on data recorded in the experimental unit of INRA from January 1993 to December 2003. Two seasons were determined a posteriori from ...
متن کاملParturition body size and body protein loss during lactation influence performance during lactation and ovarian function at weaning in first-parity sows.
We investigated the effect of body protein mass at parturition and different degrees of body protein loss in lactation on sow performance. In a 2 x 2 factorial arrangement, 77 Genex gilts were fed to achieve either a standard or high body mass at parturition and to lose either a moderate (MPL) or high (HPL) amount of protein in lactation. Pregnant gilts were fed either 24.4 MJ of ME, 266 g of C...
متن کاملDietary effects of distillers dried grains with solubles on performance and milk composition of lactating sows.
A study was conducted to evaluate the dietary effect of adding increasing concentrations of distillers dried grains with solubles (DDGS) to corn- and soybean meal-based sow lactation diets on sow and litter performance, energy and N digestibility, plasma urea N (PUN), and milk fat and protein concentrations. Mixed-parity sows [n = 307; 221 ± 15 kg of BW, 4.54 parities, litter size of 10.6, and ...
