Economic weights for performance and survival traits of growing pigs.
The objective of this paper was to derive economic weights for performance and survival traits of growing pigs including feed conversion ratio (FCR), daily feed intake (DFI), ADG, postweaning survival of the growing pig (SG), and carcass fat depth at the P2 site (CFD). An independent model was developed for each trait to derive economic values directly based on a typical Australian production s...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولThe effects of level of crude protein on performance of growing boars.
Five trials involving 432 growing boars were utilized to study the effects of six levels of crude protein on gain, feed efficiency, feed intake, backfat thickness and longissimus muscle area. The boars were fed ad libitum either a 14, 16, 18, 20, 22 or 24% crude protein diet from about 24.6 to 54.4 kg (period 1). From 54.4 to 98.8 kg (period 2), the crude protein in each diet was reduced by 2%....
متن کاملEffects of Levels of Crude Protein on Performance of Growing Boars
SUMMARY Two trials involving 216 growing boars were conducted to study the effects of different levels of crude protein on daily gains, feed efficiency, feed intake and estimated carcass characteristics. The boars were fed either a 16, 18 or 20% crude protein ration from 23.8 to 55.8 kg (period 1). Upon completion of period 1, the protein level was reduced 2% for each treatment (14, 16 and 18%,...
متن کاملEffect of active immunization against LHRH or LH in boars: reproductive consequences and performance traits.
Forty crossbred boars were equally divided into eight groups at birth. Four groups were immunized (200 micrograms/boar) at 12 wk of age against either luteinizing hormone-releasing hormone (LHRH) conjugated to human serum globulin (LHRH-hSG) in complete Freund's adjuvant (CFA), LHRH-hSG in muramyldipeptide adjuvant (PEP), procine luteinizing hormone (LH) conjugated to hSG (pLH-hSG) in CFA or ov...
