This study investigated the impact of including increasing levels of cactus pear in diets with pornunça hay on lactating goats, finding it decreased costs and nutrient intake without affecting milk production.

This study assessed how diets including pornunça hay (Manihot sp) with increasing levels of cactus pear (Opuntia ficus-indica; 0, 10, 20, or 30% dry matter) affected intake, digestibility, ingestive behavior, milk production and quality, and economic feasibility in eight multiparous lactating Saanen goats (~40 kg, ~30 days in milk), using a double Latin square (4x4) design. Adding cactus pear significantly decreased water intake and the intake of most evaluated nutrients, with these intake reductions reflected in what diets were effectively consumed, but it did not significantly change milk production or fat-corrected milk production. The inclusion also significantly reduced production costs and maintained solids composition quality, and 30% cactus pear increased economic efficiency without affecting milk output. As a preprint not yet peer reviewed, the main limitation noted is its non-final journal status, and the small sample size (n=8) constrains generalizability. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract The aim of this study was to assess the impact of diets containing pornunça hay (Manihot sp) and levels of cactus pear (Opuntia ficus-indica L. Mill) in their natural state on the intake, digestibility, ingestive behavior, milk production, and quality, as well as the economic feasibility for lactating goats. Eight multiparous goats with 30 days of lactation and an average weight of 40 ± 2.5 kg and an average production of 2 ± 1.8 kg/day were used, distributed in a double Latin square design (4x4). The treatments consisted of isoproteic diets which are composed of increasing levels of cactus pear (0, 10, 20, and 30% dry matter). Incorporating cactus pear into the diet of lactating goats resulted in a significant decrease (P0.05) milk production or fat-corrected milk production. Incorporating cactus pear into the diet of lactating goats resulted in a significant decrease (P0.05) milk production or fat-corrected milk production. The level of 30% cactus pear inclusion in the diet of lactating goats increased the economic efficiency of production without affecting milk production and maintaining a good composition of solids.
