Effects Of Dietary Betaine Supplementation On Back Fat Thickness And Serum Igf-1 In Late Finishing Pigs, Muttarin Lothong, Kittipong Tachampa, Pornchalit Assavacheep, Kris Angkanaporn
The Thai Journal of Veterinary Medicine
This study was performed in finishing pigs to investigate the effects of betaine HCl on carcass fat deposition and lipid metabolism in relation to growth hormone (GH) and insulin-like growth factor 1 (IGF-1) alterations. Sixty cross-bred finishing pigs (30 gilts and 30 barrows) with an average initial body weight of 74.0±1.8 kg were randomly allocated into two groups, each with six replicate pens. Each group was fed either 0% or 0.125% betaine HCl supplementation for 41 days. Results showed that the betaine HCl supplementation had no effect on growth performance (P>0.05). In the betaine-supplemented group, Lenden-speck-quotient index, average back …

Genetic Parameters Of Semen Quality Traits And Production Traits Of Pure-Bred Boars In Thailand, Krittaphak Buranawit, Nalinee Imboonta
The Thai Journal of Veterinary Medicine
The objective of this study was to estimate genetic parameters for semen quality and production traits of pure-bred Finnish-Norwegian boars raised in Thailand. Data used in this study were 9,760 records of semen collection and 108 records of performance tests (from 25 Duroc, 59 Landrace, and 24 Yorkshire boars). Semen quality traits considered per collection were semen volume (SV), semen concentration (SC), total sperm (TS), and total abnormality (TA). Data were recorded from 2001 to 2009, except for TA, which was not recorded until 2003. Production measures from each boar were average daily gain (ADG) and backfat thickness (BF). Results …
