Growth performance of weanling pigs fed diets with spray-dried bovine plasma or hydrolyzed spray-dried bovine plasma

Spray-dried plasma protein is commonly used in weanling diets due its functional components and high concentration of digestible amino acids. Hydrolyzed spray-dried bovine plasma (H-SDBP) is a new source of spray-dried plasma protein that may be used as a protein source in diets for weanling pigs. There are, however, no data to demonstrate the efficacy of this novel source. Pigs fed diets spray-dried plasma protein have increased growth performance when exposed to a challenge model; therefore, it is possible that H-SDBP improves performance of challenged pigs similarly as other sources of spray-dried plasma protein. Therefore, an experiment was conducted to test the hypothesis that dietary inclusion of H-SDBP is as effective as spray-dried bovine plasma (SDBP) in increasing growth performance of weanling pigs housed in uncleaned pens.

Relative bioavailability by nursery pigs of Zn in a new source of Zn-glycinate

Zinc (Zn) is an essential trace element that is needed for growth, bone development, and immune competence. Inorganic Zn sources such as Zn oxide and Zn sulfate (ZnSO4) are most commonly used in swine diets. However, because of low bioavailability of Zn the inorganic Zn sources chelated Zn sources may be used instead because these sources have greater bioavailability of Zn. Chelated zinc may also reduce reactiveness with other components of the diet. A new chelated Zn source, zinc bis-glycinate, in which Zn is bound to two glycine molecules, was recently developed, but there is limited information about effects of this new chelated Zn source on digestibility and Zn retention in pigs. Therefore, an experiment was conducted to test the hypothesis that the relative bioavailability by weanling pigs of Zn in Zn bis-glycinate is greater than in Zn mono-glycinate and in ZnSO4.

Analyzed values for P and phytate in feed ingredients

Phytic acid is the main storage of P in plants, and most P in plant feed ingredients is bound in the phytate complex. Because pigs do not secrete phytase, an enzyme to hydrolyze inositol bonds in phytate, the utilization of P by pigs is very low. Addition of supplemental phytase to diets thus results in release of P and increases P utilization by pigs. However, all enzymes have a special recognition mechanism called specificity that works only with molecules that fit to active sites of the enzyme. Therefore, it is important to know how much of P is phytate-bound and how much of the P in a given diet is not phytate-bound.

Hybrid rye may replace corn in diets for growing-finishing pigs without influencing most carcass traits, but feed intake may be reduced at high inclusion rates

Hybrid rye may replace a portion of barley or wheat in diets for growing and finishing pigs with minimal impact on growth performance or carcass characteristics, but at very high inclusion rates in finishing diets, feed intake may be reduced if hybrid rye replaces wheat. However, limited published data exist for effects of feeding hybrid rye to growing-finishing pigs in place of corn. Therefore, an experiment was conducted to test the hypothesis that average daily gain (ADG) and carcass characteristics will not differ when hybrid rye partially replaces corn in diets for growing-finishing pigs.
