Problems solved by technology

At present, there are lactation feeds specially developed for the lactation period of first-parity sows, but they only consider meeting the nutritional needs of first-parity sows for milk production, and do not consider the needs of first-parity sows’ own growth at the same time, let alone the needs of first-parity sows Influence of nutritional intake during lacta

Abstract

The invention relates to a first-born lactation period sow feed capable of reducing a sow second-born syndrome occurrence rate. The feed comprises corn, soybean meal, wheat bran, fish meal, puffed soybean, fermented soybean meal, soybean protein concentrate, soybean oil, fine aggregate, calcium hydrogen phosphate, sodium chloride, lysine hydrochloride, threonine, methionine, tryptophan and valine, and further comprises active dry yeast, isomalto-oligosaccharide, choline chloride, glucose, yeast chromium, multivitamins and composite minerals. The feed provided by the invention is reasonable and innovative in formula, and suitable for physiological characteristics of the first-born sow in the lactation period, can meet the nutrition requirements on growth of the first-born sow and growth of suckling pigs, reduces the second-born syndrome occurrence rate, and is low in cost and suitable for the actual production of the pig farm.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a lactation feed for first-born sows that reduces the incidence of second-born sow syndrome. Background technique [0002] The first litter sow is a very important link in the sow breeding process. The level of reproductive ability and nutrient reserve of the first litter sow has a great influence on the lifelong reproductive performance of the sow. Because first-parity sows are immature, they need nutrients for their own development, and after entering the lactation period, they need to supply a large amount of nutrients to piglets. Therefore, first-parity sows have higher nutritional needs than multiparous sows, but Low food intake, entering the lactation stage can easily lead to insufficient nutrient intake, resulting in a negative balance of nutrition. As a result, the sows of the first litter enter the second round of reproductive cycle and appear "second-born syndrome", whic...
