This research was conducted to determine the effects of selected inoculant on the silage with different wilting times. The ryes were unwilted or wilted for 12 h. Each rye forage was ensiled for 100 d in quadruplicate with commercial inoculant (Lactobacillus plantarum sp.; LPT) or selected inoculant (Lactobacillus brevis 100D8 and Leuconostoc holzapfelii 5H4 at 1:1 ratio; MIX). In vitro dry matter digestibility and in vitro neutral detergent fiber digestibility were highest in the unwilted MIX silages (p < 0.05), and the concentration of ruminal acetate was increased in MIX silages (p < 0.001; 61.4% vs. 60.3%) by the increase of neutral detergent fiber digestibility. The concentration of ruminal ammonia-N was increased in wilted silages (p < 0.001; 34.8% vs. 21.1%). The yeast count was lower in the MIX silages than in the LPT silages (p < 0.05) due to a higher concentration of acetate in MIX silages (p < 0.05). Aerobic stability was highest in the wilted MIX silages (p < 0.05). In conclusion, the MIX inoculation increased aerobic stability and improved fiber digestibility. As a result of the wilting process, ammonia-N in silage decreased but ruminal ammonia-N increased. Notably, the wilted silage with applied mixed inoculant had the highest aerobic stability.

Daily Gain

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.

Ruminal Fermentation

The interest in using crude glycerol in animal feeding has reemerged due to its increasing availability and favorable price resulting from the expansion of biofuel industry. The objective of the present study was to evaluate the effects of substituting corn for crude glycerol at different levels in the diet on ruminal fermentation using in-vitro true digestibility parameters. The experimental treatments consisted of substituting corn for liquid crude glycerol (0; 4; 8 and 12%) in dry matter basis. Diets consisted of 60% alfalfa hay and 40% corn and glycerol substituted the corn in the diet. In addition to the 48 hours traditionally applied in digestibility assays, different in-vitro digestibility times were used (0; 4; 8; 16; 48, 72 and 96 hours) in order to study digestion kinetics. The dietary corn substitution for increasing crude glycerol levels did not affect ammonia nitrogen content, metabolizable energy content, in-vitro digestibility of organic matter and neutral detergent fiber, nor ruminal degradation parameters. However this by-product of biodiesel production may be tested in-vivo as an alternative energy feedstuff in ruminant diets.

ABSTRACT Leaves of babassu may be used in diets for goats under maintenance, however, it is a low-quality roughage due to its high fiber content. The chemical treatment by ammonia causes reduction in the proportion of the cell wall, in addition to providing non-protein nitrogen for the microbial protein synthesis in the rumen. Babassu palm hay ammoniated with 4% urea (BHAU4%) was evaluated in this study as a substitute for guinea grass hay in the maintenance diets of goats in terms of intake, digestibility in vivo, and the partitioning of energy and nitrogen compounds. Twenty Anglo-Nubian male goats were used in a randomised block design with four treatments (diets containing 0, 33, 66, or 100% BHAU4%) and five replicates (animals/block). The chemical compositions of the feeds, leftovers, faeces, nitrogen and crude energy of the urine were evaluated. In addition, the rumen fluid pH, the rumen N-NH3, and the blood serum urea were evaluated. The digestibility of the dry matter (DM), organic matter (OM), crud protein (CP), neutral detergent fiber (NDFap) and detergent acid (ADFap), corrected for ash and protein, declined (P<0.05) 0.0939, 0.0722, 0.0953, 0.1113, and 0.2666%, respectively, with the 1% inclusion of babassu palm hay in the diet. A negative linear effect (P<0.05) was observed in the ingested nitrogen (N), excretion of N in the urine, retained N, and N balance, with decreases of 0.15711, 0.0225 and 0.1071 g/day and 0.1388%, respectively, per percentage unit of the babassu palm hay included in the diet. The intake and digestibility of the DM and nutrients are reduced with the inclusion of BHAU4% in maintenance diets for goats, with positive nitrogen balance and stability of the ruminal pH and N-NH3 as well as blood urea, which presented values within the normal physiological range for goats.
