Evaluation of different ratios of neutral detergent-soluble carbohydrate fractions on performance, ingestive behavior, and nitrogen balance in dairy goats.

Cell components soluble in neutral detergent are a diverse group, both compositionally and nutritionally. The present study aimed to evaluate production responses, behavior (eating, ruminating, and idling), and nitrogen balance of dairy goats fed different ratios of neutral detergent-soluble carbohydrate fractions. Five multiparous Alpine does with mean ± SD initial body mass of 49.

Sheep Methane Emission on Semiarid Native Pasture-Potential Impacts of Either Zinc Sulfate or Propylene Glycol as Mitigation Strategies.

The aim of this study was to evaluate the effects of Zinc sulfate and propylene glycol (PG) on methane (CH) emission, nutrient intake, digestibility, and production in sheep grazing on a native (Brazilian semi-arid savannah) pasture during the rainy season (from March to June 2014). Fifteen mixed Santa Inês sheep, all non-castrated males, with initial body weight of 19.8 ± 1.

Effects of Zinc Sulfate or Propylene Glycol on Intake, Digestibility, and Forage Selection by Grazing Sheep in a Semi-Arid Region During the Rainy Season.

The objective of this study was to determine intake, nutrient availability, and animal selection of major forage species in sheep supplemented with zinc sulfate or propylene glycol in -native pastures during the rainy season. Twenty-four mixed Santa Inês sheep, all non-castrated males, with initial weight of 19.3 ± 2.

Inactivation of lectins from castor cake by alternative chemical compounds.

Enabling the use of castor cake in animal feeding is an excellent alternative strategy to reduce feed costs. The cake is a by-product derived from the extraction of the castor oil by the biodiesel industry whose chemical composition is satisfactory despite the presence of antinutritional factors like toxic lectins, which require detoxification before it can be used as a dietary ingredient. The aim of the present study was to evaluate alternative chemical sources in the degradation and inactivation of ricin and Ricinus communis agglutinin (RCA), two lectins from castor cake.

Effect of diets with goat milk fat supplemented with exercise on anxiety and oxidative stress in the brains of adult rats.

The objective of this study is to evaluate the effects of a diet with goat milk fat supplemented with physical training on markers of oxidative stress in the brain and anxiety behavior in rats. Adult male rats were randomly divided into six groups (n = 10 per group): control sedentary (CON) and exercised (CON-EX) groups, goat milk fat sedentary (GM) and exercised (GM-EX) groups, goat milk fat enriched with CLA sedentary (GM-CLA) and exercised (GM-CLA-EX) groups. The exercised groups were submitted to treadmill running during four weeks.

Goat milk fat naturally enriched with conjugated linoleic acid increased lipoproteins and reduced triacylglycerol in rats.

Goat milk is source of different lipids, including conjugated linoleic acid (CLA). CLA reduces body fat and protect against cardiovascular diseases. In the present study fat from goat milk naturally enriched with CLA was used.

Fatty acid profile of cheese from dairy goats fed a diet enriched with castor, sesame and faveleira vegetable oils.

The addition of vegetable oils to the diets of dairy goats is an alternative to supplemental feeding during the dry period and improves the lipid profile of milk and by-products. Cheeses were produced using milk from cross bred goats (Saanen×Alpina) fed diets enriched with 4% vegetable oil (faveleira, sesame or castor), the fatty acid profile of cheeses was studied. Supplementation with vegetable oils did not increase the total fat percentage of the cheese (p≥0.

Acceleration of reflex maturation and physical development in suckling rats: effects of a maternal diet containing lipids from goat milk.

Objective: To investigate the effects of lipids from goat milk containing conjugated linoleic acids on body weight and reflex ontogeny of neonatal rats treated during the prenatal and suckling periods.

Methods: Three groups were studied: soybean oil (S), coconut oil (C), and goat milk lipids (GM). Reflex maturation (palm grasp, righting reflex, cliff avoidance, vibrissae placing, negative geotaxis, auditory startle, and free-fall righting) as well as body weight evolution were recorded during lactation.

Conjugated linoleic acid in the maternal diet differentially enhances growth and cortical spreading depression in the rat progeny.

Background: Conjugated linoleic acids (CLA) are fatty acids that are found in the lipids from goat milk, and appear to protect neurons from excitotoxicity.

Methods: We investigated in developing rats the effects of a maternal CLA-rich diet (containing 7% lipids from goat milk) on body development and cerebral electrical activity of the progeny from dams receiving the CLA diet during gestation (G), lactation (L) or both periods (G+L).

Results: Compared to a control group (C) receiving a diet with 7% soybean oil, body weight increased at 14, 21 and 28 days, but not at 35-45 days, in L and G+L groups (P<0.

Bacteria and Archaea community structure in the rumen microbiome of goats (Capra hircus) from the semiarid region of Brazil.

Most studies present in the literature about the rumen microbiome have focused on cattle and sheep. This is the first report of the characterization of the bacterial and archaeal communities present in the liquid and solid-associated fractions of the rumen from free ranging Moxotó breed goats using 16S rRNA gene libraries. PCR was used to amplify the 16S rRNA gene with bacterial and archaeal universal primers and sequences from each library constructed were obtained.

An early fish oil-enriched diet reverses biochemical, liver and adipose tissue alterations in male offspring from maternal protein restriction in mice.

Fetal programming is linked to adulthood metabolic and chronic diseases. We hypothesized that early fish oil (FO) intake would revert the programming responses in adult offspring. Pregnant mice were fed either standard chow (SC) or a low-protein diet (LP) throughout pregnancy/lactation.
