PHYSICAL PROPERTIES OF SUGARCANE (Saccharum officinarum) AND TITHONIA (Tithonia diversifolia) SHOOT-BASED WAFERS WITH DIFFERENT ADHESIVE TYPES
No full textWafers (wafer-feed) are an effective processing technology and are expected to maintain the continuous availability of animal feed during the dry season. The purpose of this study was to determine the best type of adhesive on the physical quality of sugarcane tops and Tithonia based wafers. This study used the Split Split Plot Design (SSPD). The main plot as factor A was the type of adhesive, consisting of: Tapioca flour (A1), Pathi flour (A2), Gaplek flour (A3), Karagenan flour (A4), palm sugar (A5). The subplots as Factor B are temperature which consists of: 100oC (B1), 110oC (B2), and 120oC (B3), while the sub-plots as factor C are oven time consisting of: 10 minutes (C1), 15 minutes (C2), and 20 minutes (C3). The forage used was Sugarcane tops (Saccharum officinarum) and Tithonia (Tithonia diversifolia) in the ratio of 60:40. The best adhesive in making sugarcane tops and Tithonia based wafers is tapioca flour with a temperature of 120oC for 20 minutes, with physical properties such as colour, aroma, and excellent texture with a range (3.73, 3.70, and 3.63), density with a value of 5.68 g/cm3, and water binding capacity with a value of 104.22. From the research it can be concluded that there are interactions on the physical properties of wafers (colour, aroma, and smell), density and water binding capacity. For further research, the best wafers obtained were continued to the in vitro digestibility stage to see the digestibility of wafers as ruminant feed. © The Author(s) 202
NUTRITIONAL AND CHEMICAL COMPOSITION OF SAINFOIN (Onobrychis viciifolia) ACCESSIONS IN MID-ALTITUDE OF SODDO AND ABESHGIE WOREDAS OF ETHIOPIA
No full textSainfoin (Onobrychis viciifolia) is a perennial herbaceous leguminous forage crop with a high content of crude protein, palatability, nutritive value and non-bloating. It can be offered in the form of green forage, grazing pasture, hay, or silage. To mitigate the dry season feed shortage, the agronomic performance and chemical composition of sainfoin (Onobrychis viciifolia) accessions were studied in the mid-altitude of Soddo and Abeshgie Woredas of Garage Zone of Ethiopia. For the screening, five International Livestock Research Institute (ILRI) accessions (No 5708, 16006, 6582, 10558, and 10556) and four wild sainfoin accessions were collected from Worabe, Albazer, Meskan Dubo Tuto and Gibie river basin with morphological variation. They were subjected to initial screening followed by field trials for a period of fifteen months per session. Among the twenty-nine agronomic parameters (for screening purpose), based on the dendrogram results, fifteen data points were used for location wise (Buee and Tatesa) evaluation purposes. The results indicated that, with the exception of leaf length, leaf width, and annual seed yield, all parameters were affected by the accession by location interaction. The highest (P<0.001) cumulative dry matter, seed yield, and crude protein (CP) contents were recorded for Worabe sainfoin, ILRI 5708 and ILRI 16006, respectively. Lower (P<0.05) condensed tannin (CT) was recorded in ILRI 5708, Worabe’s and Albazer’s sainfoin without any significant difference. During the first 24-hour incubation period, the highest and least (P<0.001) gases were produced from ILRI 16006 and Albazer, and ILRI 5708, respectively. The highest and least (P<0.001) methane gas was recorded from ILRI 16006 and ILRI 5708 respectively. The results indicated that Worabe sainfoin was superior to the result in all evaluated parameters. So, Worabe sainfoin hay mixture with crop residues can be used to enhance the nutritional value of crop residue-based poor feed resources. © The Author(s) 202
Effects of Aqueous Extracts of Neem Leaf and Ginger Rhizome on Growth Performance and Haematological Parameters of Pure and Crossbred Chickens
No full textNeem leaf and ginger rhizome contain numerous chemical components that are biologically active and are widely utilized in medications to treat various illnesses. The purpose of the current study was to assess the effect of aqueous neem leaf and ginger rhizome extracts on the growth performance and hematological parameters in the three breeds of chicken. A total of 360 one-day-old chicks from 3 genetic groups consisting of 120 Noiler chicks, 120 Heavy Ecotype chicks, and 120 main cross chicks were considered for this study. Each breed of chickens was randomly distributed into four groups, with three replications per group. Each replication consisted of eight females and two males, raised in a deep litter system. A 3×4 factorial arrangement was employed, involving four levels of plant extracts: a control group receiving the basal diet without any extract, a group receiving 200 ml of neem extract (NE200), a group receiving 200 ml of ginger extract (GE200), and a group receiving 100 ml of neem + 100 ml of ginger extract (NE100+GE100). The chickens were evaluated for growth parameters such as initial weight (IW), final weight (FW), average daily gain (ADG), average feed intake (AFI), feed conversion ratio (FCR) as well as some haematological parameters such as haemoglobin (Hb), packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC), platelet (P), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC). Noiler chickens receiving NE100+GE100 and GE200 showed the highest final body weight and daily weight gain. The results of the haematological indices revealed that the interaction effect of genotype and plant extracts on all the treatment groups were significantly different for haemoglobin (Hb), packed cell volume (PCV), white blood cell (WBC), and platelet (P). Some haematological indices such as Hb, PCV, WBC, and platelet were better for chickens receiving GE200 and NE100+GE100 compared to NE200 and control groups. In conclusion, the interaction of GE200 and NE100+GE100 with Noiler and main cross chickens was beneficial, with no adverse effects on the physiological traits and health status of the chickens 16 weeks of age. © The Author(s) 202
Effects of Maize, Millet, and Sorghum as Energy Sources of Diet on Growth Performance of Guinea Fowl
No full textGuinea fowls are more valuable in the market in Niger than chickens; however, their ability to meet consumer demands is limited by low productivity. Therefore, suitable nutrition is an important factor for this productivity. The current study aimed to evaluate the growth performance of guinea fowl using maize, millet, and sorghum as energy sources in the diet. A total of 108 one-day-old unsexed local keets, with an average live weight of 25.5 ± 0.83 g were randomly distributed among three dietary treatments with four replicates per treatment. The keets were reared on the ground with litter at CERRA Maradi, Niger, for an 8-week experimental period, involving 36 keets per treatment and 9 keets per replication. The parameters monitored were feed intake (FI), live weight (LW), average daily gain (ADG), and feed conversion ratio (FCR). After 8 weeks of experimentation, the results indicated that the cereal used in the diet had no statistically significant effect on the keets’ FI. Those fed millet-based diets had higher LW, compared to those fed maize and sorghum diets, respectively, however, this difference was not statistically significant. Millet also facilitated a higher ADG, compared to maize and sorghum, although the differences were statistically insignificant. The keets fed sorghum-based had higher FCR, compared to the FCR of the guinea fowls fed maize and millet diet. based on the growth performance assessed in this study, the recommended order for cereals in guinea fowl feed to ensure better growth is millet, followed by maize, and then sorghum. © The Author(s) 202
Effects of Dried Khat (Catha edulis) Leaves as a Natural Feed Additive on the White Leghorn Layers’ Performance
No full textKhat contains many bioactive compounds that are beneficial for chickens’ health. Most of the chemical constituents found in Khat are biologically active and are used worldwide for the treatment of many diseases. However, there are few studies on the use of Khat in poultry as a nutrition, antioxidant, and antimicrobial activity. Therefore, the present study evaluated the effects of dried Khat leave (DKL) as a natural feed additive on the White Leghorn layer’s performance, serum chemistry, and hematology. A total of 180 White Leghorn chickens, aged 168 days were randomly divided into four groups consisting of 45 chickens in three replications. Thirteen layers and two cocks were assigned to each replication and reared on a deep litter system. The diets of layers in T1, T2, T3, and T4 were supplemented by DKL at proportion of 0, 0.2, 0.4, and 0.6, respectively. The layers were evaluated for feed intake, body weight gain, egg production, feed conversion ratio, and some blood parameters, such as total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, albumin, globulin, red blood cells, hemoglobin, packed cells volume, white blood cells, and total protein. Feed intake in T1 (103.5 g) was significantly higher than T4 (98.5 g) and T3 (98.9 g). Layers in T1 significantly gained higher body weight than layers in other treatments. The use of DKL in layer chickens’ diet did not affect egg production, egg mass, and feed conversion ratio. An increase in the level of DKL in the layers diet significantly reduced the serum high-density lipoprotein, cholesterol, and albumin. The present study showed that chickens that received a higher proportion of dried khat leaf (0.6) significantly recorded lower levels of low-density lipoprotein and total cholesterol in their blood. © The Author(s) 202
Comparative Study of Various Diagnostic Methods for Detection of Mycoplasma gallisepticum and Mycoplasma synoviae in Egyptian Chicken Flocks
No full textThe significance of Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) in the poultry industry underscores the critical importance of diagnosing avian mycoplasmosis within the field of veterinary medicine. The present study aimed to compare various diagnostic methods for detecting MG and MS in Egyptian Chicken Flocks. A total of 360 samples were collected from breeder, layer, and broiler chickens from four governorates in Egypt. Conventional isolation methods and polymerase chain reaction (PCR) were used for the direct detection of MG and MS, while serum plate agglutination test (SPA) and Enzyme-linked immunosorbent assay (ELISA) were used for detecting antibodies against MG and MS. The highest detection rate of MG was found in commercial layers, followed by breeders, and broilers. Regarding MS, the highest detection rate was found in breeders, followed by commercial layers, and broilers. By comparing the used diagnostic methods, MG and MS were determined by the SPA test (40 and 31.1 respectively), ELISA test (31.7 and 23.6), PCR (16.7 and 11.7), and by the conventional culture method (10.8 and 3.9). It could be concluded that the serological methods and PCR gave better sensitivity than culture methods and can be used in the diagnosis of avian mycoplasmosis.

Growth Performance in Laying Ducks Fed Protein Diets Supplemented by Fresh Black Soldier Fly Larva
No full textLive black soldier fly (BSF) maggots serve as an alternative feed for ducks and other poultry, boasting a protein composition similar to fish meal. The current study aimed to evaluate the effect of live BSF maggot supplementation as a protein source on increasing duck daily production, feed conversion ratio, and egg quality. A total of 120 female Alabio ducks aged 7 months were randomly divided into 24 cages with four treatments and six replications. Each cage consisted of five ducks. Performance parameters such as daily egg production, feed conversion ratio, and egg mass production were evaluated, along with the quality of duck eggs, including egg weight, yolk weight, yolk crude protein, and albumen crude protein. The results revealed that protein levels did not significantly affect feed consumption during the laying phase for ducks. However, the comparison of duck day production between treatment groups indicated that ducks receiving lower protein levels (13.43) exhibited lower production, compared to those with higher protein levels (18.29). Furthermore, feed protein content had a notable impact on egg weight, yolk weight, and albumen crude protein. The study demonstrated a significant increase in egg yolk weight, while the percentages of egg yolk weight and eggshell weight showed no significant differences. In conclusion, this research suggests that supplementing duck diets with live BSF maggots can enhance egg quality and performance parameters. © The Author(s) 202
Antibody Response of Mice to the Bali Isolate of Canine Parvovirus Propagated in Madin-Darby Canine Kidney Cell Culture
No full textCanine parvovirus (CPV) infection is still common among dogs, leading to severe disease with high mortality. The potential of a local isolate of CPV as an effective vaccine to prevent the disease warrants investigation. This study aimed to determine the antibody response in mice against a Bali isolate of CPV propagated in the Madin-Darby Canine Kidney (MDCK) cell culture. The virus was purified using polyethylene glycol (PEG)-6000 and mixed with an Aluminum hydroxide adjuvant. Fifteen 7-week female mice were divided into three treatment groups: treatment group 1 (PEG-purified virus and Adjuvant), treatment group 2 (crude unpurified virus and adjuvant), and treatment group 3 (adjuvant without virus), with five replicates per group. The Bali isolate of CPV was successfully replicated in MDCK cells, achieving a titer of 210-211 hemagglutination (HA) units after eight serial passages through the cell culture. The virus was confirmed as CPV by immunocytochemistry test using a monoclonal antibody and hemagglutination inhibition (HI) test using chicken anti-CPV polyclonal antibody. Following the first immunization, the antibody endpoint titer in mice immunized with PEG-purified CPV (5.6) was significantly higher than those immunized with crude unpurified CPV (4.2) and adjuvant without CPV (1.4). Similarly, after the second immunization, the antibody endpoint titer in mice immunized with PEG-purified CPV (7.6) also remained significantly higher than those immunized with crude unpurified CPV (6.4) and adjuvant without CPV (0.8). Significant increases in antibody endpoint titer were observed after the second immunization in mice immunized with PEG-purified CPV and crude unpurified CPV, but not in those given adjuvant without CPV. The Bali isolate of CPV propagated in MDCK cell culture induced a robust antibody response in mice, suggesting it’s a potential as an alternative vaccine candidate for preventing CPV infection in dogs.

Effects of Combined Organic Selenium and Zinc Supplementation on In Vitro Ruminal Enzyme Activities and Relative Populations of Several Bacterial Species
No full textSelenium (Se) and zinc (Zn) are essential animal microminerals. Combining Se and Zn (Se-Zn) as a feed additive in its influence on rumen fermentation patterns is still very limited, so further investigation is needed. The present study explored the supplementation impact of combined Se-Zn from organic sources on rumen enzyme activity and relative abundance of several bacterial species through an in vitro method. Five treatments, each with six replicates were used in the study. The first group treated without Se and Zn supplementation (T0, control), the second group treated with 0.3 ppm Se + 60 ppm Zn (T1), the third group treated with 0.45 ppm Se + 60 ppm Zn (T2), the fourth group treated with 0.3 ppm Se + 90 ppm Zn (T3), and the fifth group treated with 0.45 ppm Se + 90 ppm Zn (T4). The parameters observed included rumen microbial enzyme activities (carboxyl methyl cellulase, amylase, protease) and the relative abundance of rumen microbes (Ruminococcus sp., Ruminococcus flavefaciens, Ruminococcus albus, Streptococcus sp., Prevotella ruminicola, and Eubacterium ruminantium). Results indicated that carboxyl methyl cellulase (CMC-ase) and amylase activities raised in T2, T3, and T4 in comparison to T1 and T0 treatments. Protease activity and protein enzyme content increased in T2 compared to all treatments. The relative abundance of Ruminococcus sp. and Ruminococcus albus was higher in T2 and T3 compared to T0 treatment. Furthermore, an elevated Ruminococcus flavefaciens was indicated in T2 compared to other treatments. The T2, T3, and T4 led to higher abundances of Eubacterium ruminantium, Prevotella ruminicola, and Ruminococcus albus compared to T0 and T1. It is concluded that organic Se and Zn enhanced the relative abundance of several bacterial species and the activity of enzymes in the rumen; optimal results are recommended when combining 0.45 ppm Se + 60 ppm Zn.

The Effects of Adding Coconut Water to Egg Yolk Diluent on Motility, Viability, and Abnormality of Etawa Crossbred Goat Sperm
No full textThe Etawah crossbreed goat is a dual-purpose type of goat that can adapt well to tropical regions in Indonesia. The current research aimed to evaluate the effects of adding coconut water to citrate egg yolk diluent on the spermatozoa quality parameters (motility, viability, and abnormality) of the Etawah crossbred goat at the physiology and reproduction laboratory of animal husbandry, Jambi University (Indonesia). The research employed a randomized block design on Etawa crossbreed goats aged around 2–3 years with an average weight of 12 kg per head in six groups. The treatments included 100 citrate diluent of egg yolk without adding coconut water (P0) as a control, 90 citrate diluent of egg yolk + 10 coconut water (P1), 80 citrate diluent of egg yolk + 20 coconut water (P2), 70 citrate diluent of egg yolk + 30 coconut water (P3), 60 citrate diluent of egg yolk + 40 coconut water (P4). The parameters evaluated in this study included viability of spermatozoa, spermatozoa motility, and spermatozoa abnormalities. The five treatment tubes were stored in a refrigerated cabinet at 5°C for 2 days. After this period, semen quality assessment was assessed microscopically. The percentage of live spermatozoa was determined using a staining technique. The spermatozoa motility was assessed based on their ability to move. Abnormal spermatozoa were calculated based on the number of abnormal spermatozoa compared to the total number of spermatozoa. The results of the study showed that the addition of 20 coconut water to the 80 citrate diluent of egg yolk (P2 treatment) reduced the rate of decline in spermatozoa viability and did not increase the number of spermatozoa abnormalities significantly, compared to other groups. There was no decrease in the viability of Etawah crossbreed goat spermatozoa during 2 days of storage at 5°C in all groups. Therefore, it was concluded that coconut water could be added up to 20 into the egg yolk without any significant negative effects on spermatozoa quality parameters evaluated in the current study.
