Addition of Lactic Acid Bacteria Can Promote the Quality and Feeding Value of Broussonetia papyrifera (Paper Mulberry) Silage

In this study, the influence of two lactic acid bacteria (LAB) strains [Lactobacillus rhamnosus BDy (LR-BDy) and Lactobacillus buchneri TSy (LB-TSy)] selected from Southwest China on the fermentation characteristics and in vitro gas production of Broussonetia papyrifera (paper mulberry) silage were experimentally explored. The experimental groups were a control group (C), an LB-TSy treatment (LB), an LR-BDy treatment (LR), and an LR-BDy + LB-TSy hybrid group (LR × LB). After the LAB were added, the pH value of paper mulberry silage significantly declined (p < 0.05), and the crude protein content was effectively preserved (p < 0.05). However, no significant changes were found in the levels of neutral detergent fiber, acid detergent fiber, and crude ash (p > 0.05). The lactic acid content in paper mulberry silage was evidently increased (p < 0.05). The in vitro gas production in the LR at 36, 48, and 72 h were markedly higher than that in the other treatments (p < 0.05). Owing to the addition of LAB, the microbial diversity in paper mulberry silage was reduced, while the relative bacterial abundance of Lactobacillus was enhanced. Hence, the addition of LAB selected from the warm and humid region in Southwest China can improve the quality of paper mulberry silage and elevate its feeding value in this region.

Intake, nutrient digestibility, rumen parameters, growth rate, carcase characteristics and cannabinoid residues of sheep fed pelleted rations containing hemp (Cannabis sativa L.) stubble

The feeding value and impact of hemp stubble in the diet of ruminants is unknown. Fifteen Merino castrated male sheep were maintained in individual pens and fed one of three pelletised experimental inclusion diets, as a 0% (Control), 28% (Hemp 1), and 56% (Hemp 2) pellet that delivered a diet meeting the nutrient requirements of the animals. Inclusion of hemp stubble had no effect (P &gt; 0.05) on either DM intake, live weight gain or the feed to gain ratio but positively impacted (P &lt; 0.05) on nutrient digestibility. Hemp stubble inclusion increased the concentration (but not molar proportions) of acetic and butyric acids and increased both the concentrations and molar proportions of iso-butyric, iso-valeric, hexanoic and heptanoic acids, possibly due to increased protein digestibility and/or changes in the composition of rumen cellulolytic bacteria. Tetrahydrocannabinolic acid (THCA) was the only cannabinoid found in plasma in the sheep fed the hemp-containing diets, and this was found at very low concentrations (&lt; 16 μg/L). The psychoactive cannabinoid delta-9-tetrahydrocannabinol (Δ 9-THC) was not detected in any plasma samples. THCA was detected in the liver of two sheep fed the Hemp 1 pellets and two sheep fed the Hemp 2 pellets. Cannabidiol (CBD) was detected in the liver of one sheep fed the Hemp 2 pellets (but no liver THCA was detected in this sheep). Δ 9-THC was detected in both the kidney fat and subcutaneous fat of all sheep fed hemp stubble, with the concentrations being higher (P &lt; 0.05) in the sheep fed the Hemp 1 pellets. THCA was also detected in the subcutaneous fat of one of the sheep fed the Hemp 1 pellets. Four of the five sheep fed the Hemp 1 pellet and one of the five sheep fed Hemp 2 pellet had detectable levels of Δ 9-THC in the meat (loin). No other cannabinoids were detected in the meat. Current food standards regulations in Australia prohibit presence of any cannabinoid residues in commercial meat products; thus, determination of a withholding period is required to enable the safe feeding of hemp-stubble to sheep. Further research is also required to gain a greater understanding of the rumen metabolism of cannabinoids.

Role of Live Microbes for Fermentation and Enhancement of Feeding Value of Wheat Straw as Animal Fodder

Nowadays, a resource terrible and technologically hungered farmhand within the developing nations of tropical zones faces intense challenges of their livestock farming and products due to tremendously and seriously increments of the human populace in this century. These challenges create this potential to feed human food security and not meet this sector's 2050 human population demand. The farmer faces the challenges of creating better value and sufficient harvests. Their livestock’s low-fine feedstuff-like crop-residues with low dietary due to shrinking grazing land shifted to farming land. Hence, our farmers want the generation that tackles this hassle through biological treatment to get without difficulty digested, nicely evolved flavor and nutritionally in shape, extra protein content in flip offers proper milk and red meat in-phrases of high-class besides capacity. This study aimed to determine the nutritional worth of wheat chaff treated biologically by bacterial and fungal Lactobacillus Casei Shirota and Aspergillus Niger strain. It also analyzed the physical and chemical structure of fermented chaff to obtain the numerical values that indicate the increments straw value and enhance feed intake of the individual livestock.

Analysis of Nutrient Composition, Rumen Degradation Characteristics, and Feeding Value of Chinese Rye Grass, Barley Grass, and Naked Oat Straw

The current study was designed to investigate the chemical composition, rumen degradation characteristics, and feeding value of three roughages commonly used in Asia as ruminant feed, including Chinese rye grass (CRG), barley grass (BG), and naked oat straw (NO). Four Holstein Friesian cows equipped with permanent rumen fistulas were chosen for experimental trials in the current study. The nylon bag method was carried out to measure the crude protein (CP), acid detergent fiber (ADF), ruminal degradability of dry matter (DM), and neutral detergent fiber (NDF). Our analysis revealed that the contents of CP in the CRG (9.0%) and BG (8.9%) were higher than in the NO (5.94%). The contents of NDF in the CRG (64.97%) and NO (63.83%) were lower than in the BG (67.33%), and the content of ADF in the CRG (37.03%) was lower than in the BG (37.93%) and NO (38.28%). The ED values of DM in the NO and CRG were significantly higher (p < 0.001) than in the BG. The effective degradability (ED) values of NDF were the highest in the CRG and lowest in the NO (p < 0.001). In addition, the ED values of ADF were the highest in the CRG and lowest in the BG (p < 0.001). The ED value of CP in the CRG was significantly higher than that in the BG and NO (p < 0.001). The estimated total digestible nutrients (TDN) (54.56%) and DM degradation rate (DDM) (60.06%) of the CRG were higher than those of BG and NO. In addition, the expected DM intake (DMI), estimated relative feed value (RFV), and estimated relative feed quality (RFQ) of the BG were lower than those of the CRG and NO. Altogether, based on our findings, we concluded that the nutritional quality, feeding value and effective rumen degradation rate of CRG were better than of BG and NO.

Effects of Extracts of Allium mongolicum on Safety and Quality of Pork Dry-Cured Sausage During Ripening

Allium mongolicum is a kind of plant with edible, medicinal and feeding value. The effects of ethanol and water extracts of Allium mongolicum on thiobarbituric acid reactive substances (TBARS), nitrite residue, carbonyl group, volatile base nitrogen (TVB-N) and microstructure were investigated in pork dry-cured sausages during ripening. Without added extracts groups were adopted as negative controls (CK), and adding ascorbic acid groups (VC) were used as positive controls. Results showed that compared with CK, TBARS of ethanol, water extracts and VC groups were significantly reduced. Ethanol extracts, water extracts and VC significantly decreased residual nitrite of sausages (P <0>05) comparing with CK. Ethanol extracts have better ability than water extracts in reducing carbonyl content and TVB-N. The microstructure of the CK was the worst, and the microstructure of ethanol extracts group was the best. It was concluded that ethanol extracts of Allium mongolicum could be used to produce dry-cured sausage to improve safety and quality.

Augmenting Feeding Value of Rice Distillers Dried Grain with Solubles Through Dietary Addition of Enzymes in Broilers

Background: Substitution of expensive protein sources like soybean meal with lower cost ingredient like rice distillers dried grain with solubles (rDDGS) would reduce the cost of the feed. Various enzymes supplementation may be used to increase their inclusion level. Methods: An in-vivo study of 42 days was undertaken (n= 384) in broilers divided into 12 dietary treatments as per 3x4 factorial design. Two levels of rDDGS consisted of 12.5 and 15% without and with three different types of enzymes xylanase, protease and multienzymes were used to find out substract specific enzyme. Result: Overall the growth performance of broiler chicken was significantly lower at 15% rDDGS level as compared to control and 12.5% rDDGS level. However, it was significantly (P less than 0.01) improved by supplementation of any of the three enzymes (xylanase, protease and multienzymes) in 12.5 and 15% rDDGS groups. Nitrogen retention, dry matter and energy metabolizability were significantly (P less than 0.01) improved in all enzymes supplemented groups. The cost of feed per kg live weight and meat yield was significantly (P less than 0.01) lower at 12.5% rDDGS with enzymes supplementation. Thus, it is concluded that the enzymes supplementation can increase inclusion level of rDDGS from 12.5 to 15% for economic broiler production.

Effect of Napier grass ensiled with or without inclusion of soy waste on the performance of growing goats

Utilization of soy waste as a ruminant feed is low due to storage problems and transportation costs.An experiment was carried out with fifteen goats to assess the feeding value of Napier grass(Pennisetum purpureum) ensiled with or without soy waste. Grass ensiled without soy waste wastermed as NM silage, while grass ensiled 30% soy waste (w/w) was termed as NMS silage. In bothsilages, 1.0% molasses (w/w) were incorporated to enhance the fermentation process. After 2months of ensiling, three diets were formulated and assigned to one of three groups: (i) Napier grassad libitum plus 1% pellet of body weight (BW) on a dry matter (DM) basis (T1), (ii) NM silage adlibitum plus 1% soy waste of BW on a DM basis (T2), and (iii) NMS silage ad libitum (T3). TheNMS silage showed a lower pH (4.04 vs. 4.64) than NM silage. The NMS silage exhibited higherproportions of DM, organic matter (OM), and crude protein (CP) compared to NM silage. Animalsreceived T1 diet showed higher (p<0.05) DM, OM and neutral detergent fibre intake compared tothe animals received T2 and T3 diets. However, animals received T2 diet showed higher CP intakethan the animals received T1 and T3 diets. Similarly, animals received T2 diet showed higher(p<0.05) BW gain (49.4 vs. 16.5 g/d) than the goats fed T3 diet. In conclusion, the T3 diet mayhave limited goat performance, which needs further study to improve the quality of silage.
