Molecular Diagnosis of the Main Hemoparasites of Dairy Cows in the State of Ceará.

Background/objectives: Trypanosomiasis and bovine babesiosis correspond to important diseases that cause great economic losses, but there are still no studies evaluating their occurrence in herds of dairy cattle in Ceará. The aim of this study was to perform molecular diagnosis of the main hemoparasites of dairy cows in the microregion of the central hinterland of Ceará.

Methods: For the molecular diagnosis of parasites, genomic material was extracted and polymerase chain reaction directed to the cdCatL-like gene for and SS rRNA of and was performed.

Growth performance and body composition of feedlot lambs fed refused melon fruit.

This study aimed to evaluate the effect of replacing corn grain with refused melon fruit (RMF) in the diet on the intake and digestibility of nutrients, performance, carcass characteristics, and physical-chemical attributes of meat from lambs finished in feedlot. We used 30 male lambs of the Santa Inês breed, not castrated, with 18.3 ± 1.

Effects of refused melon fruit in Canarana grass ensilage on intake, digestibility, serum biochemistry, performance, carcass characteristics and meat attributes of feedlot lambs.

Ensilage of refused fruit with forage is a viable approach to increase resource use in ruminant feed. The objective of this study was to investigate the impact of ensiling refused melon fruit (RMF) with Canarana grass on the intake, apparent digestibility, serum biochemistry, performance, carcass traits, and meat attributes of feedlot lambs. Four distinct silage treatment types were prepared by ensiling RMF at 0 g/kg (control), 70 g/kg, 140 g/kg, and 210 g/kg (as fed) with Canarana grass.

Cactus species and tree forage hay in the diet of dairy goats.

The purpose of this study was to evaluate the influence of the association of Opuntia stricta (OS) or Nopalea cochenillifera (NC) with Moringa hay (MY) or Leucaena hay (LY) on nutrient intake, ingestive behavior, serum biochemistry, and milk production and composition of dairy goat. Eight multiparous Saanen goats were used, with an average of 68 ± 8 days in milk and 48.5 ± 6 kg of initial weight, fed with the following treatment diets: OS + MY; OS + LY; NC + MY, and NC + LY.

Enhancing Titanium Disk Performance through In-Pack Cold Atmospheric Plasma Treatment.

While titanium dental implants have already been clinically established, ongoing research is continuously being conducted to advance the fields of osseointegration and bacterial resistance, seeking further improvements in these areas. In this study, we introduce an innovative method for treating titanium surfaces within tightly sealed packaging. Specifically, titanium discs, enclosed in surgical-grade packaging, underwent treatment using cold atmospheric plasma (CAP).

Phytogenic Bioactive Compounds in the Diet of Lactating Sows, Litter Performance, and Milk Characteristics.

The objective was to evaluate the effect of phytogenic supplementation in the feed of lactating sows on the performance parameters of sows and suckling piglets. Ninety-three lactating sows of commercial lines (sows TN70) were distributed in a completely randomized design. The treatments adopted were a control diet without phytogenics (control) and a control diet with phytogenic supplementation in the feed.

Hematology and biochemistry of buffalo (Bubalus bubalis): influence of sex and age on reference values.

This research aimed to obtain a hematological and biochemical profile of buffalos (Bubalus bubalis) bred in a region of the Brazilian Legal Amazon. A total of 73 animals of mixed races, divided into three groups, were studied: group 1 (G1) comprised animals up to 11 months old; in group 2 (G2), subjects were 12 to 23 months old; and, in group 3 (G3), they were 24 months old and older. We performed the hematological analysis manually, and, for the biochemistry, we used biochemical analyzers.

Follicular right shift: Xenografting queens' ovarian tissue into severe combined imunnodeficiency mice and its responses to exogenous gonadotropin.

Ovarian xenografting is an auxiliary reproductive technique that allows the conservation of germplasm of high-value livestock and endangered species. The use of exogenous gonadotropins assists in developing xenografted tissues and obtaining viable follicles for in vitro embryo production; however, this use has not been reported in the xenografting of cats' (Felis catus) ovaries with C57BL/6 female SCID mice (Mus musculus) as recipients. Therefore, the aim of this study was to evaluate the responses of queens' ovaries to eCG when grafted into C57BL/6 female SCID mice.

Gossypol promotes degeneration of ovarian follicles in rats.

The present study aimed to determine if gossypol interferes with ovarian follicles in rats. Twenty-four female Wistar rats were assigned to two equal groups: one control group and the other dosed with gossypol (25 mg/kg/day, subcutaneously) for 15 days. Ovarian follicles were histologically classified according to the stage of development and as normal or atretic.
