The purpose was to evaluate the effect of replacement of Tifton 85 hay with Guandu hay on the intake, digestibility and ingestive behavior of dairy goats. Five Saanen goats with average milk production of 2.26 ± 0.10 kg d-1, around 123 ± 4 days of lactation were assigned to a 5 x 5 Latin square design. The treatments consisted of five levels of replacement with Guandu: 0, 8.4, 16.8, 25.2, or 36.4 %. We sampled the food offered, leftovers and feces to calculate intake and digestibility, and the ingestive behavior was monitored for 24 hours. Regression analysis was applied with 5% significance. The nutrient intake and the digestibility of dry matter, organic matter and protein decreased linearly with increasing levels of Guandu hay in the diet (p < 0.05). On the other hand, the neutral detergent fiber digestibility increased linearly, without change the water intake and ingestive behavior with replacement levels of Tifton hay with Guandu hay in the diet (p < 0.05). The replacement of up to 36.4% Tifton hay with Guandu hay in the dairy goat diet reduces the intake and digestibility of dry matter, organic matter and protein, and increasesfiber digestibility, without changing the ingestive behavior and water intake.

This study aimed to assess the nutrient intake and milk production of dairy goats fed with total mixed rations with different species of forage cacti. Five pluriparous Saanen goats (50 ± 4 kg) at nine weeks of lactation were allocated in a Latin square (5 x 5) with five diets and five periods. Each period was composed of 10 days for adaptation and seven days for collection. The treatments were composed of 473.0 to 501.0 g kg-1 of forage cacti: xiquexique (Pilosocereus gounellei), mandacaru (Cereus jamacaru), facheiro (Pilosocereus chrysostele), cactus cladodes cv. miúda (Nopalea cochenillifera Salm-Dyck) and cactus cladodes cv. orelha de elefante mexicana (Opuntia stricta); plus sabiá hay (Mimosa caesalpiniifolia) (188.0 to 198.0 g kg-1) and concentrate (311.0 to 329.0 g kg-1). The intake of dry matter, organic matter, ether extract, neutral detergent fiber, total carbohydrates, and water intake through diet components were unaffected by experimental diets. For milk production and feed efficiency, no difference was observed among the diets. All diets containing different species of forage cacti can be used for dairy goats feed.

ABSTRACT The aim of the present study was to assess the effects of replacing corn silage with sugarcane in the diet of lactating Saanen goats and to determine their intake and digestibility of nutrients, ingestive behavior, milk yield and composition. The experimental diets were composed of increasing levels (0, 33, 66 and 100%) of substitution in dry matter (DM). Twelve multiparous Saanen goats, with an average body weight of 45.2kg, average milk yield of 3.0kg day-1, distributed in a triple latin square experimental design (4 × 4) were used. The dry matter intake (DMI) and other nutrients were estimated through the difference between the total nutrient in the food offered and its total in the leftovers. The DMI, crude protein, neutral detergent fiber (NDF) and total digestible nutrients were not influenced, but the apparent digestibility of DM and NDF decreased. Feeding time and feeding efficiency were not influenced, the rumination and total chewing times increased, and the leisure time decreased, both linearly. Milk yield was not influenced by substitution levels, but corrected milk yield to 3.5% fat decreased. Sugar cane represents a dietary alternative for goats with medium milk yield in critical periods of forage, since it does not change the consumption of DM and milk yield, even with the apparent declining digestibility of some nutrients, influencing the ingestive behavior of the animals.

The objective of this trial was to evaluate the effect of the partial replacement of corn by forage cactus (Nopalea cochenillifera Salm Dyck) in the diets of lactating goats on the nutrient intake, milk production and composition and ingestive behavior. Five crossbreed Saanen x Pardo Alpina goats with body weights of 47 ± 3.3 kg were used in the study. The design was 5x5 Latin square design, in which the treatments were as follows: 20, 25, 30, 35 and 40% of girl cactus included in the diet as a partial replacement of corn, with 0, 18, 36, 54 and 72% of the added the cactus comprising of gliricidia (Gliricidia sepium (Jacq) Walp) as roughage in all treatments. Treatment did not affect (P > 0.05) the dry matter intake, crude protein, neutral detergent fiber, acid detergent fiber and total digestible nutrients with the increasing levels of cactus in the diet, presenting means of 1.64, 0.26, 0.82, 0.54 and 1.17 kg day-1, respectively. In the same way, no influence was observed on the daily milk production and levels of fat, protein, lactose and total solids of milk, which averaged 1.18 kg day-1; 3.74, 3.34, 5.06 and 13.56%, respectively. The inclusion of cactus also had no influence (P > 0.05) on the ingestion behavior. The treatment with 35% cactus showed a lower impairment of food intake (31%). The partial replacement of the corn by the girl cactus in the diets of dairy goats can be accomplished because it does not alter the intake, milk yield and composition and feeding behavior. The replacement of up to 54% corn by the cactus is recommended to reduce producer costs for food.

Abstract The objectives of this research were to evaluate the effects of source and concentration of α-amylase-treated neutral detergent fiber (aNDF) from roughage on feed intake, ingestive behavior, and ruminal kinetics in beef cattle receiving high-concentrate diets. Six ruminally cannulated Nellore steers (408 ± 12 kg of body weight) were randomly assigned to a 6 × 6 Latin square design with six diets: 10% aNDF from corn silage (10CS); 20% aNDF from corn silage (20CS); or four diets containing 10% aNDF from corn silage and 10% aNDF from one of the following sources: sugarcane (SC), sugarcane bagasse (SCB), soybean hulls (SH), or low oil cottonseed hulls (LOCH). The parameters of passage and degradation kinetics were estimated based on a two-compartmental model with gamma- and exponential-distributed residence times. The nonlinear models were fitted by nonlinear least squares, and a linear mixed-effects model was fitted to all variables measured from the Latin square design that were related to intake, digestibility, digestion kinetic parameters, and residence times. Mean particle size (MPS) between roughage sources (CS, SCB, and SC) and coproducts (SH and LOCH) was affected (P &lt; 0.05). Dry matter intake (DMI) was not affected (P &gt; 0.05) by 20CS, SC, SH, or LOCH. Steers fed 20CS or LOCH diets had 16% and 20% greater DMI, respectively, (P &lt; 0.05) than steers fed 10CS diet. Steers fed SCB consumed the least dry matter (DM). The SH and LOCH diets had lower MPS values (about 8.77 mm) in comparison to 20CS, SCB, and SC diets (about 13.08 mm) and, consequently, affected (P &lt; 0.05) rumen content, ruminal in situ disappearance, nutrient digestibility, and solid fractional passage rate. Chewing time was affected (P &lt; 0.05) by roughage sources and concentration. Lower values of distance travel inside the rumen (min/cm) were observed (P &lt; 0.05) for the SCB and SC diets in comparison with any other diet. Except for SCB, there was no difference (P &gt; 0.05) in rumen fill, among other treatments. Mean daily ruminal pH was not affected (P &gt; 0.05) by 20CS, SCB, SC, and LOCH diets, and it ranged from 6.1 to 6.23. Total short-chain fatty acids concentration was affected (P &lt; 0.05) by roughage source and concentration. Based on our results, we recommend that under Brazilian finishing diets, replacing roughage sources, except for SCB, based on aNDF concentration of the roughage in high-concentrate diets containing finely ground flint corn does not affect DMI.

<p>This study aimed to evaluate nutrient intake and digestibility by sheep fed diets containing residue from the extraction of tamarind pulp (RETP). We used four sheep with a mean body weight (BW) of 40.38 kg, whose pens were distributed in a Latin square design. The diet treatments contained 0, 5, 10 and 15% of RETP. The variables were subjected to analysis of variance and the differences observed were tested using regression equations at 5% significance. The intake of dry matter (DM), organic matter (OM), crude protein (CP), total carbohydrates (TC), and non-fiber carbohydrates (NFC),expressed in g day-1, % BW and g kg0,75-1, were not significantly affected (p&gt;0.05) by the inclusion of RETP. The intake of ether extract (EE) and neutral detergent fiber (NDF) showed a linear increase (p&lt;0.05) as RETP content rose. However, the digestibility of DM, CP, TC, and total digestible nutrients (TDN) decreased linearly (p&lt;0.05), while the digestibility of EE, NDF, ADF, and NFC, with average values of 62.12%; 79.95%; 41.59%; 37.12%, and 91.57%, respectively, were not significantly affected (p&gt;0.05) when RETP was included in the diet. The inclusion of up to 15% of the residue from the extraction of tamarind pulp changes the intake of ether extract and neutral detergent fiber, and reduced dry matter, crude protein, and total carbohydrates in the sheep’s diet.</p>

The objective of this study was to evaluate nutrient intake, in vivo digestibility, and in situ degradability of different cultivars of hay (i.e., [Jiggs] and [Tifton-85] bermuda grass (Cynodon spp.) and [alfalfa] (Medicago sativa) and [stylo] Campo Grande (Stylosanthes sp.)) and nitrogen balance in sheep. We used eight rumen-cannulated F1 Santa Ines × Dorper castrated male sheep with body weights of 35.0 kg in a double 4 × 4 Latin Square experimental design. The intake and total apparent digestibility of nutrients were higher (P<0.05) for alfalfa than for stylo hay. The in vivo dry matter (DM) digestibility of Jiggs (47.6%), Tifton-85 (53.4%), stylo (29.3%), and alfalfa (53.2%) hays and in situ DM degradability were equivalent in the range of 7.6 to 63.2 h of degradation. The in vivo neutral detergent fiber (NDFap) digestibility of Jiggs (53.7%), Tifton-85 (64.4%), stylo (42.2%), alfalfa (56.2%), and in situ NDFap degradability were equivalent from 37.3 h. Nitrogen balance was negative only in animals fed stylo hay. Alfalfa hay provides a higher nutrient intake than other hays. The alfalfa and bermuda grass hays used in sheep diets presented better digestibility than stylo hay. The results are suitable to predict in vivo digestibility from in situ degradability parameters.

It was aimed to evaluate the effect of inclusion and times of sugar cane exposition to whitewash on intake and total and partial digestibility of nutrients and ruminal parameters and to compare titanium dioxide and chromium oxide as markers to estimate fecal dry matter excretion and dry matter abomasal flow. It was used six rumen and abomasum cannulated Nellore females, with average body weight of 250 ± 19 kg, distributed in an incomplete 6 x 6 latin square design. The experiment was set in a 3 x 2 factorial scheme with three levels of whitewash (0; 0.5 or 1.0% natural matter) and two times of sugar cane storage (0 and 3 days). There was no effect of storage times neither interaction among levels of whitewash and storage times on the intake of nutrients. However, levels of whitewash linearly increased consumption of dry matter (DM), organic matter (OM) and non-fibrous carbohidrates (NFC).Storage times reduced total apparent digestibility of dry matter, organic matter and neutral detergent fiber corrected for ash and protein (NDFap), but they did influence ruminal apparent digestibility of the nutrients. The inclusion of whitewash increased the consumption of total digestible nutrients (TDN), but it did not affect total digestibility and ruminal digestibility of the nutrients. The markers produced similar results for the estimates of total and ruminal apparent digestibility of all the evaluated nutrients. Interactions for ruminal pH were observed. However, values of amonical nitrogen were only influenced by sampling times. Addition of whitewash does not affect preservation of sugarcane, but it positively influences consumption of DM, OM, and TDN of the animals. The markers produced similar estimative to total tract and ruminal apparent digestibility of all nutrients. Titanium dioxide and chromium oxide markers produce similar estimates of digestibility.

This study aimed to evaluate the effect of different non-fibrous carbohydrate (NFC):neutral detergent fiber (NDF) ratios (0.70:1, 0.90:1, 1.14:1, 1.42:1, and 1.85:1) in diets containing cactus cladodes on intake, digestibility, ruminal parameters, ingestive behavior, and microbial protein of growing heifers. Five rumen-cannulated heifers (194 ± 70 kg of body weight) were distributed in a Latin square design (5 x 5). There was a quadratic effect on the intake of dry matter (DM) (Kg day-1 and %BW) and crude protein (CP) with the increase in non-fibrous carbohydrate (NFC): neutral detergent fiber (NDF) ratio, with maximum values of 7.07 kg day-1, 2.86%, and 0.949 kg day-1, estimated for 1.37:1, 1.39:1, and 1.27:1 ratios. When the intake of NDF decreased, in turn, the intakes of NFC and TDN increased. The NDF digestibility decreased with increasing NFC levels in diets. The other nutrients were not influenced. The ruminal pH showed the lowest values at 4 hours after feeding, mainly for animals fed the 1.85:1 ratio. There was a quadratic effect for rumination time with maximum values estimated for an NFC:NDF ratio of 0.88:1. The time spent idle increased linearly, while total chewing time and feeding efficiency of NDF decreased. The urinary volume increased linearly. However, microbial protein synthesis and the efficiency of the synthesis were not influenced. The number of protozoa increased by 64.5% with the elevation of the NFC:NDF ratio. We recommend a NFC:NDF ratio of 1.37:1 in diets containing cactus cladodes, to improve the use of nutrients, without negatively affecting ruminal parameters.
