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 …

Immunological castration of boars temporarily reduces testosterone concentration, testis size and function, without long term effects on libido and sperm quality
… objective was 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 = …

Evaluating lipid oxidation and sensory characteristics in bacon from immunologically castrated barrows
With increased time after immunological castration, lipid content of bacon increases and unsaturated fatty acid content is reduced. Our objective was to determine the effect of immunological castration (Improvest®, gonadotropin releasing factor analog-diphtheria toxoid conjugate, Zoetis) management …

Effects of feeding ractopamine (Paylean®) to immunologically castrated (Improvest®) pigs on growth performance, carcass yields, and further processing characteristics
… 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 …

Evaluating fat quality and bacon slicing yields in immunologically castrated barrows
… dissertation was to determine 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 …

Growth performance and carcass characteristics of immunologically-castrated barrows in comparison to intact males, physically-castrated barrows, and gilts
… performance and carcass characteristics 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 …

Effects of gonadotropin releasing factor immunological (Improvest®) on carcass characteristics, pork quality, and further processing characteristics of finishing male pigs
… testicular function of male pigs using an immunological designed to block the communication of gonadotropin releasing factor (GnRF) with the anterior pituitary gland. This disrupts the production of a number of male sex hormones such as testosterone and androstenone. The reduction of …
