Effects of feeding ractopamine (Paylean®) to immunologically castrated (Improvest®) pigs on growth performance, carcass yields, and further processing characteristics
… of immunologically castrated (IC; Improvest, Zoetis, Kalamazoo, MI) pigs. With costs of production rising in the swine industry, producers are constantly seeking methods to improve growth performance while keeping production costs minimal. Two technologies that have been beneficial …

Effects of gonadotropin releasing factor immunological (Improvest®) on carcass characteristics, pork quality, and further processing characteristics of finishing male pigs
… in United State swine production systems. Improvest® (Pfizer Animal Health, Kalamazoo, MI) is a 9 amino-acid base pair GnRF conjugate that prevents boar taint in entire male pigs even when allowed to grow to ending live weights over 130 kg. This research used two populations of pigs of PIC …

Growth performance and carcass characteristics of immunologically-castrated barrows in comparison to intact males, physically-castrated barrows, and gilts
… of immunologically-castrated (with Improvest®) barrows relative to other genders. The first study evaluated the growth performance of immunologically- and physically-castrated barrows, intact males, and gilts from wk 16 of age (67.2 ± 2.52 kg BW) to a pen mean BW of 132.5 ± 3.60 kg. …

Immunological castration of boars temporarily reduces testosterone concentration, testis size and function, without long term effects on libido and sperm quality
… to determine the effects of immunocastration (Improvest) on reproductive characteristics in boars. Seventy-two boars were used in a randomized design with three treatments: single injection (SI) or double injection (DI) of Improvest, and intact controls (no Improvest; CNT) (n = 24/group). At wk …

Evaluating fat quality and bacon slicing yields in immunologically castrated barrows
… the effects of immunological castration (Improvest; Zoetis, Kalamazoo, MI) on lipid deposition, fresh belly quality and bacon slicing yields. Immunological castration allows producers to capitalize on the increased feed efficiency and leanness associated with intact males while controlling …

Evaluating lipid oxidation and sensory characteristics in bacon from immunologically castrated barrows
… the effect of immunological castration (Improvest®, gonadotropin releasing factor analog-diphtheria toxoid conjugate, Zoetis) management strategies [age of slaughter, and time after second dose (ASD)], on lipid oxidation and sensory characteristics of bacon packaged under simulated food …

Effect of immunological castration on color stability, shelf life, and sensory characteristics of fresh and further processed pork
Improvest® (Zoetis, Kalamazoo, MI) an immunological product for intact male pigs that stimulates the production of antibodies against gonadotropin-releasing factor (GnRF), temporarily blocking its activity and causing temporary castration. Use of Improvest delays castration, taking advantage of …
