[Experimental studies on a decrease in hypotrophy in newborn piglets in commercial swine raising].

Area of Science:

• Animal Science
• Veterinary Medicine
• Reproductive Biology

Background:

• Hypotrophic piglets, born with significantly lower live weight and vitality, pose a substantial challenge in swine breeding operations.
• These piglets often succumb to mortality within 40 hours, impacting herd productivity and economic returns.
• The incidence of hypotrophic piglets is reported at 7% in reproductive bases and 10% in commercial swine breeding complexes.

Purpose of the Study:

• To investigate the efficacy of protein hydrolysate and glucose supplementation in reducing the incidence of hypotrophic piglets.
• To evaluate the impact of this treatment on piglet vitality, live weight, and susceptibility to diseases.
• To explore the underlying biological mechanisms, particularly the role of essential amino acids, in preventing hypotrophy.

Main Methods:

• A study involving 402 pregnant pigs treated with protein hydrolysate and glucose injections, alongside vitamin-mineral feed additives.
• A control group of 395 pregnant pigs received no such treatment.
• Comparative analysis of hypotrophic piglet rates, live weights, vitality, and disease incidence between the treated and control groups.

Main Results:

• A two-fold decrease in the birth of hypotrophic piglets was observed in the treated group compared to the control.
• Treated piglets exhibited higher live weight and improved vitality.
• The incidence of coli bacteriosis and other diseases was significantly lower in the piglets from the treated group.

Conclusions:

• Supplementation with protein hydrolysate and glucose is an effective method for preventing piglet hypotrophy in hybrid industrial swine breeding.
• The beneficial effects are likely linked to the provision of essential amino acids, crucial for fetal development.
• This model scheme offers a practical and economically viable solution for improving swine production outcomes.
