Lactating Cows

The aim of this study was to determine the best level of utilization of dried waste of cassava starch extraction (WCSEd) as a substitute for corn for lactating cows. Four lactating cows were fed diets with increasing levels (0%, 33%, 66% and 100%) of WCSEd as a substitute for corn. The intake and digestibility of dry matter and nutrients, milk production and composition, blood parameters of glucose and urea and microbial synthesis of the diets were evaluated. There was a reduction in dry matter intake, organic matter, ether extract and total carbohydrate, and increased intake of acid detergent fiber. Nutrient digestibility was not affected while the synthesis of microbial protein increased. These changes resulted in reduced milk production, without altering the efficiency of production or the constituents of milk, with a decreasing effect on daily production of lactose, solids and minerals. Metabolic parameters, glucose and urea nitrogen in plasma, remained within appropriate levels. The dried residue from the extraction of cassava starch can be used as feed for dairy cows to replace up to 100% of the corn ration. However, its use promotes a reduction in intake of dry matter and nutrients as well as a reduction in the production of milk, with impacts on the profitability of the product.

Spineless cactus is an important part of dairy cow diet in the semiarid Brazilia. Severe infestation of cochineal (Dactylopius opuntiae Cockerell) destroyed a vast area of the most common species of cactus planted in the region; Opuntia ficus-indica Mill. resistant varieties with superior agronomic performance were recently selected, but they still need to be tested with dairy cows. We evaluated the use of a resistant variety, ‘Orelha de Elefante Mexicana’ (OEM, Opuntia spp.), in dairy cow diet. We tested its effect on intake, nutrient digestibility, microbial protein, blood parameters and performance of lactating cows. Ten cows with an average milk yield of 20 kg/day were assigned to an experiment using a double 5 × 5 Latin square design. The experimental diets consisted of five replacement levels of Nopalea cochenillifera Salm Dyck cv. (‘Miúda’) by ‘OEM’ (0%, 25%, 50%, 75% and 100%) on a dry-matter (DM) basis) and were formulated considering the ingredient composition. The roughage:concentrate ratio was 70:30 on a DM basis. The replacement of ‘Miúda’ by OEM did not change the intake (kg/day) of DM (18.0), organic matter (16.3), crude protein (CP, 2.8), total digestible nutrients (11.6), non-fibre carbohydrates (7.6) and neutral detergent fibre (5.7), or the apparent digestibility (g/kg) of DM (655), organic matter (694), CP (739) and non-fibre carbohydrates (950), whereas apparent digestibility of neutral detergent fibre increased linearly. Microbial protein production (1.5 g/day), microbial protein efficiency (129.2 g CP/kg total digestible nutrients), plasma urea nitrogen (21.4 mg/dL), nitrogen balance (123 g/day), feed efficiency (1.1), nitrogen efficiency (0.2), milk production (20.0 kg/day), fat-corrected milk production (20.1 kg/day) and milk composition were not influenced by the replacement. Therefore, we recommend the use of OEM in the diet of lactating cows with an average milk yield of 20 kg/day.

This study aimed to evaluate dry matter intake, nutrient digestibility, milk production and composition, and feed efficiency of cows fed corn grain silages with okara or raw soybean inclusion. Six Holstein cows were distributed in a double Latin square and arranged in the following treatments: concentrate formulated based on corn grain silage with 30% okara inclusion; concentrate of corn grain silage with 20% raw soybean inclusion, and concentrate based on dry corn grains. Statistical analysis was performed using Bayesian inference. Diets formulated with silages reduced dry matter intake compared to the diet of concentrate based on dry grains. High digestibility of DM, OM, NFC, and EE was observed for diets with silage inclusion. Milk presented an increase in CLA for the diet of corn grain silage diet with soybean inclusion. Rehydrated grain corn silage with soybean or okara inclusion reduced dry matter intake and increased nutrient digestibility, maintaining the same milk production, which demonstrates the higher efficiency of these diets.

Friesian Cows

AbstractThe present experiment evaluated the inclusion of chelated phytogenic feed additives mixture in the diet of lactating cows for the first 3 months of lactation. A week before calving, thirty multiparous Friesian cows were divided into three treatments in a complete randomized design and fed a basal diet without supplementation (Control treatment), or the control diet supplemented with chelated phytogenic additives at 3 g (PHY3 treatment), or at 6 g/cow/d (PHY6 treatment). Menthol, levomenthol, β-linaloolm, anethole, hexadecanoic acid and pmenthane were the principal compounds identified in the additives mixture. Milk production, total solid, protein, fat, and lactose were increased with PHY3, but decreased by PHY6 (P<0.01). Whereas the PHY3 treatment increased (P<0.05) milk contents of Ca and Zn, PHY3 and PHY6 treatments increased (P<0.05) milk Fe and Mn concentrations. Though the PHY3 treatment increased (P<0.05) nutrient digestibility, the PHY6 treatment decreased (P<0.05) the digestibility of organic matter, crude protein and neutral detergent fiber. The PHY3 treatment increased (P<0.05) ruminal volatile fatty acids (VFA) concentration and proportional acetate and propionate and decreased butyrate, while the PHY6 treatment decreased ruminal VFA concentration and proportional acetate. The PHY3 treatment increased (P<0.05) serum total protein, glucose, total antioxidant capacity, and the concentrations of Ca and Zn. Both PHY3 and PHY6 treatment decreased (P<0.05) the concentrations of serum triglycerides, and cholesterol. Daily inclusion of 3 g/cow of chelated feed additives mixture in diet of lactating cows improved milk production and ruminal fermentation, but additives dose of 6 g/cow/d had negative impact on cows’ performance.

Lactating Buffaloes

The experiment was conducted to study the effects of supplementing a cellulase enzymes cocktail to lactating buffaloes’ diet, on the nutrient intake, nutrient digestibility, and milk production performance and composition. Twenty-four lactating Egyptian buffaloes were assigned into one of the following treatments: CON—control consisted of a total mixed ration, CENZ—the total mixed ration supplemented by a commercial source of cellulase enzyme, FENZ—the total mixed ration supplemented with cellulase enzyme cocktail produced in-farm. Supplementing the diet with the in-farm source of cellulase (FENZ) had a significantly higher impact on crude protein, neutral detergent fiber, and acid detergent fiber digestibility. However, FENZ tended to increase the EE digestibility compared to CENZ. FENZ showed significantly higher nutrient digestibility percentages compared to other groups. Supplementing the diet with cellulase enzymes (CON vs. ENZ) significantly increased the daily milk yield and the fat correct milk yield; both yields were significantly higher with FENZ than all groups. Oleic, linoleic, and linolenic acid concentration were significantly higher with cellulase enzymes supplementation (CON vs. ENZ) and the conjugated linoleic acid concentration. Supplementing fungal cellulase enzyme produced on a farm-scale has improved milk productivity, fat yield, and milk fat unsaturated fatty acids profile in lactating buffaloes.
