对于规模化猪场来说，提高能繁母猪年断奶仔猪数及降低单位增重生产成本，是成本控制的关键，而采购成本和生产过程成本控制也不可忽视。能繁母猪生产能力强，是指年提供断奶仔猪多，单位产出成本低，反之，断奶仔猪少1头，就会将母猪及公猪的各种饲养成本分摊到仔猪身上，-costs will be higher accordingly. Therefore, improving the production capacity of breeding pigs is an effective method to reduce production costs.

To achieve this goal, we should take several measures. Firstly, we need to minimize non-breeding days, as they significantly affect the number of piglets born per year from a sow. The key to reducing non-breeding days is to improve farrowing rates; high farrowing rates lead to fewer non-breeding days. It's essential to promptly check for pregnancy and reduce false pregnancies by strictly adhering to artificial insemination protocols and minimizing returns-to-mating.

Secondly, we should shorten the interval between weaning and breeding. Healthy sows typically come into heat within seven days after weaning, while those in poor condition may delay ovulation by one or even two estrous cycles.

Thirdly, increasing the number of liveborn piglets per litter is crucial. This can be achieved by improving the quality of boars and ensuring timely checks for heat and proper timing for breeding.

Lastly, strengthening management practices tailored to different stages of growth ensures precise feeding based on individual needs and adherence to specific feeding standards at each stage. By maintaining good health in pigs through these measures - multiple ovulations and few stillbirths - productivity can be optimized while keeping costs under control.

In conclusion, enhancing efficiency in pig farming requires careful attention not only towards cost control but also towards animal welfare through well-managed practices that prioritize their health.

By adopting such strategies as minimizing downtime periods during reproduction processes (farrowing rate), optimizing reproductive schedules (weaning-to-breed intervals), maximizing successful births (live-born offspring), refining overall management techniques (precision feeding) coupled with a focus on animal care & welfare all contribute positively toward achieving desired results: improved output efficiency with reduced production expenses.

In essence then it's about nurturing healthier animals which ultimately leads both better yields & lower operational expenses.
