Cactus cladodes for dairy goats: what is the best fiber source?

This study evaluated the effect of different fiber sources supplied with cactus cladodes in diets on the intake and digestibility of nutrients, ingestive behavior, milk yield, and composition of dairy goats. The fiber sources were corn silage, sorghum silage, Digitaria pentzii Stent. hay, and sugarcane bagasse.

Nutritional effects of using cactus cladodes (Opuntia stricta Haw Haw) to replace sorghum silage in sheep diet.

The aim of the present study was to evaluate the effects of replacing the sorghum silage in sheep diet with cactus cladodes [CC - Opuntia stricta (Haw) Haw] on dry matter and its compound intake and digestibility, feeding behavior, and nitrogen balance. The diets consisted of five replacement levels [0, 200, 400, 600, and 800 g/kg on a dry matter (DM) basis] and were formulated to be isonitrogenous [140 g/kg crude protein [CP], considering the ingredients' composition, with a roughage/concentrate ratio of 65:35, on a DM basis. Five uncastrated crossbred sheep, with an average body weight of 52.

Cactus cladodes associated with urea and sugarcane bagasse: an alternative to conserved feed in semi-arid regions.

The objective of this study was to evaluate the nutritional value of different roughage sources as an exclusive feed for goats and sheep from the determination of nutrient intake and digestibility. Five goats and five sheep were used and arranged in a double 5 × 5 Latin square design. Treatments consisted of cactus Nopalea cochenillifera (L.

Quality of meat from sheep fed diets containing spineless cactus (Nopalea cochenillifera Salm Dyck).

It was aimed to evaluate the effects of replacement of wheat bran in lambs' diets with spineless cactus (0, 33, 66, and 100%) in a lamb's diet on the physicochemical parameters, fatty acids and sensory analyasis of meat. The evaluation utilized 36 loins and legs from F1 ½ Dorper × ½ Santa Inês lambs, with an average initial body weight of 19.5 ± 1.

Can the body composition of crossbred dairy cattle be predicted by equations for beef cattle?

Objective: The aim of the study was to evaluate the efficiency of the Hankins and Howe (HH46), Valadares Filho (V06), and Marcondes (M12) equations for predicting the physical and chemical composition of dairy crossbred bulls carcasses, as well as the chemical composition of their empty bodies.

Methods: This study was conducted using 30 dairy crossbred bulls. One group of five animals was slaughtered at the beginning of the experiment, and the remaining were slaughtered 112 days later.

Sugarcane bagasse as exclusive roughage for dairy cows in smallholder livestock system.

Objective: The study aimed to evaluate sugarcane bagasse as roughage in lactating cow on feed intake, digestibility, ingestive behavior, milk production and composition, and microbial protein synthesis.

Methods: Ten Girolando cows at initial body weight of 450±25.6 kg and at 143.

Replacement of Tifton hay by spineless cactus in Girolando post-weaned heifers´ diets.

This study aims to evaluate the effect of the Tifton 85 hay (Cynodon dactylon L. Pers) replacement by Orelha de Elefante Mexicana spineless cactus (Opuntia stricta [Haw.] Haw) on the nutrient intake and digestibility, growth performance, microbial protein synthesis, and efficiency of dietary nitrogen compound utilization in the diets of Girolando heifers.

Carcass characteristics of lambs fed spineless cactus as a replacement for sugarcane.

Objective: Fresh sugarcane has been a new roughage source for ruminant's in semiarid regions, a function of the decline of sugar and alcohol industry in recent years. However, there is little data published regarding lambs fed sugarcane associated with spineless cactus. This study evaluated the effect of sugarcane replacement with spineless cactus (0%, 33%, 66%, and 100%) in the diet of Santa Inês lambs on carcass characteristics.

Spineless cactus as a replacement for sugarcane in the diets of finishing lambs.

The effects of replacement of sugarcane by spineless cactus (0, 33, 66, and 100 % on dry matter (DM) basis) were evaluated on intake, digestibility of nutrients, ingestive behavior, and performance of finishing lambs. Thirty-six non-castrated Santa Ines lambs at 4 months of age and an initial body weight of 22 ± 2.3 kg were assigned in a randomized block design.

Feed handling of lactating crossbred cows maintained in a semi-arid region during the hot season: physiological parameters, ingestive behavior and performance.

The effects of time of feed delivery (14.00 hours; 14.00 and 20.

Performance and carcass yield of crossbred dairy steers fed diets with different levels of concentrate.

The objective of this study was to evaluate the influence of diets with increasing concentrate levels (170, 340, 510 and 680 g/kg of total dry matter) on dry matter intake, digestibility, performance and carcass characteristics of 25 Holstein-Zebu crossbred dairy steers in a feedlot. A completely randomized design was used, and data were submitted to analysis of variance and regression. The dry matter intake and digestibility coefficients of all nutrients increased linearly.

Replacement of wheat bran with spineless cactus (Opuntia ficus indica Mill cv Gigante) and urea in the diets of Holstein x Gyr heifers.

The aim of this study was to evaluate the replacement effect of wheat bran with spineless cactus and urea in heifers. Twenty-four heifers with an average initial weight of 185 ± 13 kg were used in this experiment. Four levels of spineless cactus corrected with urea and ammonium sulfate (9:1) were studied: 0, 33, 66, and 100 % replacement with wheat bran.
