Effect 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 کاملEstimation of Genetic Parameters for Rectal Temperature in Sows Rearing in a Tropical Humid Climate and Its Association with P
The objective of this study was to evaluate the genetic parameters of thermoregulation traits and its association with sow’s performance during lactation. A total of 94 lactating Large White (LW) sows, rearing in a tropical humid climate were used in this experiment. The genetic parameters of rectal temperature measured at 0700 and 1200 (RT7 and RT12), the difference between RT12 and RT7 (dRT),...
متن کاملEffects of dietary protein level and amino acid supplementation on performance of mixed-parity lactating sows in a tropical humid climate.
Eighty-six mixed-parity Large White sows were used to determine the effect of diets with reduced CP content or supplemented with essential AA on 28-d lactation performance under humid tropical climatic conditions. This experiment was conducted in Guadeloupe (West French Indies, latitude 16 degrees N, longitude 61 degrees W) between February 2007 and January 2008. Two seasons were distinguished ...
متن کاملThe impact of season, parity and breed on selected reproductive performance parameters of sows
The aim of the study was to identify the detailed impact of the season, parity and breed on reproductive performance of sows. The experimental material consisted of 2100 sows, in 3 breed variants: 700 PL, 700 PLW, 700 crossbreeds PL×PLW. Sows were observed until parity 5. In the context of the breed, depending on the order of parity groups of 140 sows were isolated. Then, sows were divided in t...
متن کاملEffects of dietary fiber on performance of multiparous lactating sows in a tropical climate.
Sixty-two multiparous Large White sows were used to determine the effect of dietary fiber level on lactation performance according to season under conditions of a humid tropical climate. This experiment was conducted in Guadeloupe (West French Indies, lat 16 degrees N, long 61 degrees W) between October 1999 and January 2001. Two seasons were distinguished a posteriori from climatic measurement...
