This study aimed to evaluate the effects of crude protein (100, 130, 160 and 190 g kg -1 of dry matter) of diets composed of 200 g kg -1 of Tifton 85 grass hay and 800 g kg -1 of pelleted concentrate on intake, nutrient digestibility, production and composition of milk in lactating goats. Eight female Saanen goats with 42.7 ± 1.43 kg and 57.7 ± 7.37 days of lactation and milk production of 2 ± 0.22 kg at the beginning of the experiment were housed in individual 1.32 × 3.10 m stalls and distributed into two 4 × 4-balanced Latin squares. Intake of dry matter, organic matter, crude protein, neutral detergent fiber corrected for ash and protein, ether extract and total digestible nutrients showed a quadratic effect, with maximum intake of 2.030; 2.000; 305; 769; 55 and 1.574 g day -1 at the levels of 140.7; 140.8; 189.2; 140.9; 144.9 e 142.7 g kg -1 DM, respectively. Digestibility of dry matter, organic matter, crude protein, non-fibrous carbohydrates, ether extract and total digestible nutrient level varied linearly, with increases estimated at 0.54; 0.50, 2.02, 0.49, 0.80 and 0.63 g/100g for each percentage unit of protein added to the diet, respectively. Milk production was affected, with increase of 0.54 g for each 1% crude protein added to the diet. Milk lactose level decreased linearly, unlike the fat level, which increased linearly. Protein level showed a quadratic behavior, with a maximum of 36.7 g per kg of milk at the level of 160.5 g per kg of DM. It is recommended to use crude protein between 135 g and 150 g per kg of dry matter of diets consisting of 800 g of pelleted concentrate (composed of soybean meal replacing the alfalfa hay as protein source) per kg of DM for lactating goats producing 2 kg of milk per day.

“…For the quantification of fibrous fractions -neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, cellulose and lignin, the sequential method described by Van Soest et al (1991), with Ankon Fiber Analyzer equipment was used, with polyester bags (non-woven textile, TNT), weight 100 mm (Araújo et al, 2009). Prior to determining the fibrous fractions, the samples were defatted by the Soxlet method, and the yields of ethereal extract samples were obtained by the same method (Komarek, 1993).…”

-The objective of this study was to evaluate the effect of inclusion of lipid residue of biodiesel originated in the processing of palm oil (Elaeis guineensis) in the diet on the digestibility of feedlot lambs. Twenty-five crossbred male castrated lambs, weighing 20±1.61 kg, were distributed in randomized blocks with five treatments and five replications. The experimental period lasted 22 days; 15 for diet adaptation, 2 for the adaptation to the indicator LIPE (lignin from Eucalyptus grandis isolated, purified and enriched, UFMG, Minas Gerais) and 5 for fecal sampling. Diets were formulated with 64% concentrate based on corn and soybean meal, 31% Massai grass (Panicum maximum cv. Massai) hay and 5% lipid supplementation from increasing levels of substitution of 0, 25, 50, 75 and 100% of palm oil for biodiesel oil from palm residue. The lambs were offered two meals a day, at 7h00 and 16h00. There was linear effect of inclusion of the residue from palm oil biodiesel on dry matter intake. There was no change in digestibility of nutrients except for ether extract. The use of biodiesel from palm oil residue up to 100% replacement for the lipid supplementation of sheep positively influences the consumption without altering the digestibility of nutrients.

“…In addition to the amount of fodder, the quality also oscillates over time, which makes it difficult to define food programs. A strategy used in the dry season for dairy goat is the intensification in the production model with the collection of animals to management centers or small areas for the most suitable feeding, allowing even rest in the pasture areas, and sustainable management of the caatinga ecosystem (Araújo, Medeiros, Carvalho, Silva, & Chagas, 2009).…”

The objective of this study was to evaluate the use of sorghum silage, Buffel grass hay and forage palm fodder in the diet of dairy goats by means of performance tests and economic viability of different roughage sources. Eight Anglo-Nubian goats, multiparous, weighing around 40.13 ± 2.76 kg of live weight were used. The experiment lasted 84 days, consisting of four periods of 21 days, distributed in two Latin squares (4x4). The treatments represented by diets with different volumetric sources: SSCF: (sorghum silage+ forage palm+ concentrate); BHCF: (Buffel grass hay + cactus forage+ concentrate); SS: (sorghum silage+ concentrate) and BH: (Buffel grass hay + concentrate). Nutritional intake, digestibility, feed behavior, milk production and chemical composition and economic analysis were evaluated. Animals fed the BHCF diet had higher nutrient intakes and consequently were more productive in fat, protein, lactose, fat free solids and total solids. The BHCF diet led to a higher gross income in Brazilian currency. The safety margin of the SSCF diet presented the highest percentage, with 43.06%, and the BHCF diet, the lowest percentage, of 14.89. The association of forage palm with sorghum silage and Buffel grass hay can be used as a bulky source in lactating goat diets.
