EFFECT OF DIETARY CRUDE PROTEIN LEVELS ON FEED INTAKE AND NUTRIENT DIGESTIBILITY OF WAGYU CROSSBRED CATTLE
No full textThe objective of the experiment was to determine the suitable crude protein level on feed intake and digestible nutrient value of Wagyu crossbred cattle from 13 to 20 months of age. The research included 2 experiments. Experiment 1: five male Wagyu x Zebu crossbred cattle (12.2±0.56 months of age and average live weight of 179±24.2 kg, Mean±SD). Experiment 2: five male Wagyu x Zebu crossbred cattle (16.7±1.05 month�s old and live weight of 276±22.0 kg). Two experiments were Latin square design (5x5) with 5 treatments and 5 periods (21 days per period). The treatments were different crude protein levels at 210, 245, 280, 315, and 350 g per 100 kg live weight (LW) corresponding to CP210, CP245, CP280, CP315, and CP350 treatments, respectively. The basal diet was commercial concentrate (1.2 kg/day), fresh Elephant grass (5.0 kg/day) and ad libitum rice straw. While soybean meal was used to adjust the dietary CP level per 100 kg LW in diets. The result showed that increasing nutrient consumption and metabolism energy (P0.05) by increasing crude protein levels. Experiment 1: the CP digestibility was highest (P0.05) with CP245 (62.9) and CP315 (71.7) treatments. Experiment 2: the highest CP digestibility (P<0.05) of CP350 treatment as compared to CP315, CP280, CP245, and CP210 treatments (80.2, 77.4, 73.1, 70.5, and 65.0, respectively). As a result, increasing CP levels per 100 kg BW could rise nutrients digestibility and digestible value for Wagyu crossbred cattle. The level of 245 g CP per 100kg live weight in Wagyu crossbred cattle diet from 13 to 20 months of age could be recommended for application. © (2023), (Scienceline Publication). All Rights Reserved
MORPHOLOGY AND REPRODUCTIVITY PROFILING OF MALE SENDURO GOATS BASED ON AGE DIFFERENCES
No full textSenduro goats, a local breed of meat and dairy goats from Indonesia, are recognized for their significance in improving goat breeding and preserving valuable genetic resources. However, limited information exists regarding the reproductive physiology of Senduro goats, which poses challenges to the development of breeding programs and the preservation of genetic resources. This study aimed to investigate the morphological and reproductive profiles of male Senduro goats at different ages, focusing on morphological characteristics, mating behavior, and sperm quality. Morphological characteristics are assessed through body length measurements, while mating behavior serves as an indicator of reproductive behavior. Macroscopic evaluations of sperm quality include assessments of color, viscosity, pH, and volume, while microscopic examinations encompass motility (mass and individual), viability, and spermatozoa membrane integrity. The results showed morphological similarities between juvenile and adult samples, with their testicular size being the only significant difference. Based on macroscopic and microscopic examinations, no significant differences were found between groups. From the results it was concluded that there were no distinct differences in morphological characteristics, mating behavior, and sperm quality between male Senduro goats in the juvenile and adult stages. © The Author(s) 202
Campylobacteriosis in Poultry: A Review
No full textCampylobacter is common in poultry, including layer and broiler chickens, geese, ducks, and turkeys. This review aimed to emphasize the prevalence of campylobacteriosis, recent poultry diagnoses, and strict prevention measures. Campylobacter species colonize the intestines of poultry and waterfowl but are generally nonpathogenic in poultry. However, they are the most common bacterial cause of sporadic human enteritis in both developed and developing countries. The main species responsible for campylobacteriosis is Campylobacter jejuni, followed by Campylobacter coli. A number of other Campylobacter species, such as Campylobacter lari, fetus, upsaliensis, and hyointestinalis are rarely associated with campylobacteriosis. Campylobacter hepaticus is the species linked to spotty liver disease in layers and breeder chickens, and it may be the etiological agent of the disease previously known as avian vibrionic hepatitis. The most prevalent infection source for Campylobacter is environmental contamination from poultry droppings. However, some Campylobacter species can be transmitted vertically, either on the surface of eggs or via trans-ovarian transmission in addition to consumption of contaminated feed or water. Due to the non-specific clinical signs such as diarrhea and weight loss, diagnosing campylobacteriosis in poultry requires culture or polymerase chain reaction tests. Little is known about the available vaccine or effective antibiotic treatment due to the rapid development of antibiotic resistance. Therefore, strict biosecurity measures play a crucial role in preventing Campylobacter infection in commercial poultry. These measures include decontaminating housing between flocks, preventing the entry of rodents, wild birds, and animals, and eradicating insects. To control campylobacteriosis and reduce infection risks, it is important to implement efficient on-farm biosecurity measures, conduct regular inspections of workers at meat processing plants and poultry farms, and ensure thorough preparation of chicken meat and eggs before consumption. These measures are vital in minimizing the Campylobacter transmission from both broiler and laying chickens, thereby reducing the risk of foodborne diseases caused by contaminated food
Molecular Characterization of the NRAMP1 Gene and Blood Parameters of Sinai and Lohman Brown Chickens in Egypt
No full textIn almost all animal species, natural resistance-associated macrophage proteins (NRAMPs) have been linked to disease resistance. It plays a crucial part in innate immunity and can affect adaptive immunity as well. The aim of this study was to investigate some immunological traits and molecular genetics in the native breed of chickens, named Sinai (S) and a commercial strain of Lohman Brown (LB). The NRAMP1 gene was reported to be associated with a defense mechanism against infection by bacteria and viruses. A total of 144 female day-old chicks, including 72 from the commercial layer strain (LB) and 72 from the Egyptian native chicken strain (S), were used in this study. At 38 days of age, blood samples were taken randomly from 8 chickens of each group for serum antibodies against the New Castle disease virus, avian influenza virus, and infectious bursal disease virus analysis. Additionally, genomic DNA was extracted from 20 blood samples at 38 days of age. Polymerase chain reaction (PCR) analyses were conducted on the DNA samples, followed by sequencing of the PCR products to identify single nucleotide polymorphisms (SNPs) in the NRAMP1 gene in the two strains of chickens. The findings indicated that lymphocyte, eosinophil, phagocyte activity, and IgY were significantly greater in LB chicks than in S chicks. Sinai chickens, on the other hand, achieved dominance in Newcastle titter. Eight SNPs were found in NRAMP1 of the two strains. The nucleotide identity between S and LB nucleotides was 58.68%, while the changes in different amino acids were found in different positions. Multiple SNPs in the NRAMP1 gene have been discovered in Sinai and LB, suggesting that this gene can be used as a genetic marker for the selection of high-producing indigenous hybrids with the ability to resist pathogenic diseases in poultry
Effects of a Vitamins D and C Supplement on Performance, Hatchability and Blood Profiles of Broiler Breeders
No full textVitamin D is a fat-soluble vitamin that plays a crucial role in controlling Calcium and Phosphor homeostasis, bone mineralization, and modulation of immune responses. Vitamin C is a cofactor of enzymatic reactions with anti-inflammatory and antioxidant properties to prevent and repair damage to cells in the body from exposure to free radicals and the immune system. The current study aimed to investigate the effects of dietary supplementation of 25(OH)D3 with vitamin C at different doses on broiler breeders’ blood profile, egg quality, and hatchability. The adaptation process before collecting the data was 2 weeks. A total of 6200 females and 620 male broiler breeders in the laying period aged 32-46 weeks were divided into 4 treatment groups with 5 replicates (each peach contained 310 female and 31 male breeders). The treatments included control as T0 (0 g/ton Nutricell HyC®), T1 (100 g/ton Nutricell HyC®), T2 (200 g/ton Nutricell HyC®), T3 (400 g/ton Nutricell HyC®) supplemented in feed. The observed variables were performance in breeding farms and hatcheries. The treatments with experimental doses indicated significant differences in the performance of broiler breeders, including feed intake, body weight, egg weight, egg mass, hen day production, hen house production, feed conversion ratio, and parameters of blood profile. The results showed a significant difference between the treatments and the control group in terms of hatch performance, clear eggs, exploding eggs, hatchability eggs, fertile eggs, salable chicks, and hatching of fertile eggs. However, no significant effects on fertility, culling of chicks, and embryonic mortality in the treatment groups were indicated. In conclusion, Nutricell HyC® with a dose of 400 g/ton in feed has indicated the best result in breeding farm and hatchery performance of broiler breeders in the laying period
PRODUCTIVITY OF THE TSIGAI SHEEP BREED UNDER DIFFERENT FEEDING REGIMENS
No full textABSTRACT: In the present study, the influence of levels of feeding on the formation and development of economic and commercial traits of the Tsigai breed was studied in the conditions of the southern steppe of Ukraine. The research was conducted on purebred sheep from birth to 14 months of age. For this purpose, 2 groups of 3.5-4 years old ewes of the first class were selected with 40 heads in each class. It was established that poor feeding of ewes (experimental diet and below standard nutritional levels) and their offspring at the early stage of ontogenesis had a negative effect on the formation and growth of productive qualities of lambs, means of live weight and wool productivity indicators. Qualitative and quantitative indicators of wool were better in ewes obtained from mothers of the control group (who received a balanced diet in accordance with the standard of feeding). Advantage in length of wool at 12 months age was 29.3, shearing of unwashed wool (26.7), washed (26.5), strength of wool at 4 months of age (10.5), and in the 14th month aged was 5. The improvement in housing and nutrition conditions in the control group proved that the counts were better and this had a very positive effect on the productivity of the sheep. In conclusion, full-fledged feeding of ewes of the Tsigai breed ensured good development of offspring at all stages of ontogenesis and contributed to the birth of healthy, viable lambs that are capable of high productivity. Any decline in nutrients of Tsigai sheep breed (from standards of commercial formula) can cause considerable deficiency in productivity of animals. © (2023) Scienceline Publication
EFFECTS OF DIFFERENT PROCESSING METHODS ON NUTRIENT CONTENTS AND ACCEPTABILITY OF HOG PLUM (Spondias mombin Linn.) LEAF BY WEST AFRICAN DWARF SHEEP
No full textThree experiments were conducted to evaluate the effect of processing method on leaves from Spondias mombin tree as fodder for ruminants in the tropics. The leaves were subjected to three different physical processing methods; T1 control (fresh but air drying), T2 (fresh but soaked in ordinary water for 24 h then air drying), and T3 (fresh but soaked in water at 50oC for 20 min then air drying). Nutrient and secondary metabolites content were determined in experiment 1. In experiment II, the Coefficient of preference (CoP) was determined. In vitro gas production was used to predict metabolizable energy (ME), organic matter digestibility (OMD), short-chain fatty acid (SCFA) and methane (CH4) of S. mombin leave with different processing methods in experiment 111. Results revealed significant differences in the chemical composition of S. mombin leaf subjected to different processing methods. The dry matter value was highest in S. mombin leaves soaked in hot water (90.22), and lowest in S. mombin leaves soaked in water at room temperature (85.05). Crude protein was highest in leaf processed with hot water (11.25 ) and lowest in control (9.59 ). No significant variations were observed for minerals and anti-nutrients investigated. The Vitamin content of leaves of S. mombin tree with various processing methods differed significantly except for vitamin E. The preference coefficient value was greater in leaves soaked at 50oC for 20 mins than leaves from the other processing method and control. All leaves of S. mombin tree from all processing methods considered in this study were acceptable to the animals, but leaves soaked in 50oC for 20 mins were most preferred. The in vitro gas production parameters and characteristics were not significantly different. In conclusion, S. mombin leaf subjected to 50 oC for 20 mins is more advantageous as forage in animal nutrition than unprocessed. © 2023, Online Journal of Animal and Feed Research.

AVIAN CELLULITIS: A SKIN AFFECTION ASSOCIATED WITH ECONOMIC LOSSES IN BROILER CHICKENS
No full textThis review was designed for focusing on cellulitis condition in broiler chickens regarding causes, clinical picture, and prevention measures of this condition. Cellulitis is an acute diffuse inflammation of subcutaneous tissues and muscles especially on the skin of thighs and abdomen. This condition is more common in broilers than others and it is usually associated with economic losses. At processing, low grade chicken carcasses and high incidences of condemnation are the sequels of cellulitis. Skin integrity, stocking density, and litter conditions are predisposing factors for induction of cellulitis. However, other infectious bacterial and immunosuppressive viral pathogens are associated with cellulitis. Affected birds display areas of yellow skin along with a plaque of pus underneath the skin and the underlying muscles show hemorrhages. Presence of caseous, yellowish to green, dark red, or brown fetid gangrenous exudate could also be observed in the advanced cellulitis cases. Prevention and control of cellulitis are based on application of hygienic practices, vaccination, antibiotic therapy, genetic selection, and nutrition. © 2023, Online Journal of Animal and Feed Research.

No full textThe current study evaluated the effect of feeding clove (Syzygium aromaticum) as a natural additive on productive performance, digestibility and nutritive value, antioxidant enzymes activities, and immune response of growing rabbits. A total of 48 New Zealand White (NZW) rabbits aged 6 weeks were randomly allocated to 4 groups (12 rabbits/group). Clove buds powder (CLP) was supplemented at 0.5, 1, and 1.5 of basal diet. Four tested diets formulated to contain basal diet without CLP (treatment 1, T1), 0.5 CLP (T2), 1 CLP (T3), and 1.5 CLP (T4). The animals were provided pelleted diets and fresh water ad libitum throughout the experimental period. The rabbits fed diets containing CLP improved FCR (P=0.007) and consumed (P0.05) with rabbits fed CLP diets when compared to those fed the control diet. In conclusion, using CLP as an alternative feed additive in rabbit’s diets up to 1.5 without any adverse effect on productive performance and vital activities. The CLP inclusion in rabbit diets decreased feed intake (FI), improved FCR and increased profitability, moreover, had a positive effect on antioxidant enzyme activity and immunity (IgG and IgM) titres. © 2023, Online Journal of Animal and Feed Research.

SYMPTOMATIC REPONIBLE UMBILICAL HERNIA IN THE RABBIT
No full textA case of umbilical hernia in a 7-month-old female rabbit was presented to the Surgery Clinic of the Veterinary Faculty, University of Sarajevo. The owner noticed inappetence and lethargy four days before arrival at the clinic. Clinical parameters on physical examination were within the physiological range. Bruxism and lethargy were noted as signs of discomfort due to gas accumulation in colon. A reponible, nonpainful mass in the umbilical scar area was palpated but intestinal peristalsis was not altered. General anesthesia was induced by intramuscular administration of ketamine with medetomidine and maintained with isoflurane. Surgical treatment of hernia included the peritoneal sac dissection and amputation, repositioning of small intestines, and correction of abdominal wall defect. Intraoperative multimodal analgesia approach was used to reduce inhalant anesthesia requirements and to prevent pain-related and stress-related complications. In this case report we described a surgical and veterinary treatment of the reponible umbilical hernia in a rabbit. © 2023, Online Journal of Animal and Feed Research. All Rights Reserved
