Vitamin C supplementation is important for the growth and development of bullfrog tadpoles under optimum water temperature conditions. Therefore, an experiment was carried out to evaluate the effects of vitamin C supplementation on the diet of bullfrog tadpoles at a low temperature. A total of 480 tadpoles with a mean weight of 0.078 g were distributed in 12 aquariums each containing 40 L of water in a closed water recirculation system. The experimental design was entirely randomized with four treatments (0, 150, 300, and 600 mg kg-1 of L-ascorbic acid monophosphate) and three replicates. The productive performance was measured by the weight gain, feed conversion, diet consumption, protein efficiency, carcass yield, hepatosomatic index, viscerosomatic index, visceral fat index, dry matter, and ethereal carcass extract. The water temperature during the experimental period was 21.74 ± 0.43 °C. Vitamin C supplementation did not influence carcass yield and viscerosomatic index. However, there was a quadratic effect of vitamin C supplementation on the weight gain, apparent feed conversion, protein efficiency, visceral fat index, hepatosomatic index, and ethereal carcass extract. Based on these results, bullfrog tadpoles should be supplemented with 600 mg vitamin C kg-1 of the diet when subjected to water temperatures of around 22 °C.

Feed quality very depends on changes in the weather where in short rainy conditions the feed is abundant, mean while, long dry conditions cause feed availability to be limited. One of the abundant feeds is rice straw, but the use of rice straw needs to be considered for its nutritional content, thus its utilization requires to be processed first. This study aimed to utilize local microorganisms (MOL) of Bali cattle rumen fluid at different inoculum levels on the quality of fermented rice straw silage to over come feed shortages in dryland. The study used a completely randomized design (CRD) with 4 treatments and 4 replications, namely R0: Rice Straw + Rice Bran 10% + molasses 3% (Without MOL of cattle  rumen fluid/control); R1 : Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle  rumen fluid 5%; R2 : Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle  rumen fluid 10%; R3: Rice Straw + Rice Bran 10% + molasses 3% + MOL of cattle  rumen fluid 15%. The percentage of molasses and cattle  rumen fluid was adjusted to the weight of chopped rice straw. Data were analyzed using analysis of variance (Anova). The results showed that the treatment had a significant effect (P<0.05) on the organoleptic quality (color, texture, smell, presence of fungi and pH) and organic matter, crude protein, extract eter, crude fiber, carbohydrate, nitrogen free extract and gross energy (nutritional content) of rice straw silage, dry matter and gross energy had no significant effect (P>0.05). It can be concluded that the higher MOL of cattle  rumen fluid level use, the greater organoleptic quality and nutritional content of rice straw silage obtained

Diabetes mellitus is a chronic disorder that results in hyperglycemia by absolute or relative insulin deficiency, sometimes leading to fatal complications. The successful treatment of diabetic dogs depends on nutritional management and insulin applications. Studies evaluating the nutrition of diabetic dogs focused on fiber as the main factor in glycemic control; however, new research describes the role of starch as key in postprandial glycemic fluctuation, also attributing a central role for body condition scores and feed management in the adequate glycemic control of diabetic dogs. The aim of this paper is to review nutritional aspects to better control diabetes in dogs.

Nutritional risk factors for liver damage were surveyed in Black-Pied French dairy herds using serum glutamic dehydrogenase and gamma glutamyl transferase levels to monitor liver dysfunction.The 34 herds chosen were free of parasitic liver injuries. Feeding systems, nutritional blood parameters and production characteristics are analyzed. Two risk factors appeared to be involved in hepatic injury: feeding of fresh rape (Brassica napus) and high levels of serum urea (>/=6.64 mmol/L) associated with grass pasture or dietary nonprotein nitrogen with corn silage

The present study aimed to evaluate the economic feasibility of production and commercialization project of Hay Enriched Extruded (HEE) as a complete diet for horses. The study was based on survey data and quotation activities involving price from the land preparation (repair, planting and fertilization) to the processing of the product at the factory (extrusion) and marketing. Transportation costs and taxes were also considered. Discounted Cash Flow (30 years) was used to calculate the profitability indicator and the Profit and Loss Statement (PLS). Calculations were developed using Microsoft Office Excel® spreadsheets. Three production scenarios were simulated with different consumer prices: Scenario 1 - equivalent to the complete diet, where the ingredients are supplied together, but purchased separately; Scenario 2 - Considering a value 10% higher than the complete diet; Scenario 3 - Considering a value 20% higher than the complete diet. We observed that the project was economically viable in the three suggested scenarios with positive Net Present Value, Internal Rate of Return greater than 9.4% and payback of 11 to 2 years. The results enable us to conclude that the product may be a promising investment for both product quality and ease of use as the rapid return on invested capital.

Indigenous sheep are highly adaptable and widely distributed in different regions of Bangladesh. They are famous for their tolerance to harsh environmental conditions, low demand for feed, and disease resistance with minimum or no housing and management facilities. Ample indiscrimi¬nate research reports and case studies on the native sheep of Bangladesh have been published. Nonetheless, a comprehensive review of reproductive and productive performances, as well as their various morphometric physiognomies and climate resilience capabilities, is lacking. This review was designed to explore and summarize the available research reports on indigenous sheep to highlight the gaps and provide an updated database for the future research plan for sustainable native sheep production in Bangladesh. It covers studies on sheep biodiversity, their adaptabil¬ity to the local environment, morphometric features, feeding and nutrition, reproduction and production performances, diseases and health management, and the problems and prospects of sheep farming in Bangladesh. Due to the increased demand for animal protein, especially red meat, the scope of sheep farming increases along with that of other large and small ruminants. The vital constraints of sheep production in Bangladesh include insufficient feed and fodder sup¬ply with its high prices, higher disease occurrence with low or no management practices, kid mortality, and a poor marketing channel with the lower popularity of sheep meat than goat meat. Future research would be a prerequisite to measuring the impact of native sheep on household economies and food security during the year, evaluating the other challenges, and finding out the possible interventions in the fields of nutrition, reproduction, and health management.

The domestic rabbit is a commonly kept pet in many countries, including Norway. This study aimed to survey the current health and welfare of pet rabbits in Norway based on recommendations for rabbit keeping put forth by the Norwegian Food Safety Authority and the Norwegian Veterinary Institute. An online questionnaire consisting of 65 questions was shared online. Data collection lasted from March to May of 2021 and yielded 513 responses from pet rabbit owners representing all Norwegian counties. Forty-five percent of the rabbits were female, 53.6% were male and most of the rabbits (76.0%) were neutered. Almost all rabbits (97.5%) had permanent access to hay. Complete pelleted feed was the most fed concentrate (n=492, 95.9%). Almost all rabbits (96.9%) were reported to be healthy at the current moment. Of the surveyed disease conditions, constipation (19.7%), diarrhoea (12.3%), and reduced appetite (17.9%) were the most common. Dental disease was reported in 29 rabbits (5.7%). The veterinarian was a source of information for 49.1% of rabbit owners. Most rabbits (86.2%) were kept in a living space above the recommended 200x300 cm. Although keeping conditions were reported to be of a high standard, pet rabbits were still suffering from preventable husbandry-related diseases. Education of rabbit owners is an important task of the veterinarian and should focus especially on feeding habits, and owner recognition of rabbit behaviour and diseases.

Minimising health problems and increasing yield have always been the objectives in livestock agriculture. Hence, increases in incidences of reproductive conditions in cattle farming pose a great threat to productivity and impose undesirable economic implications. This study aimed to examine the concentrations of different biochemical compounds in cows with reproductive conditions. Seventy-seven blood samples were collected from cows at different rural areas around Mafikeng, following cases of downer cow syndrome, dystocia, retained placenta, vaginal prolapse and abortion. Means of serum metabolites across the different reproductive conditions were statistically compared using Pearson's chi-square test to determine variations of serum metabolites in cows of different breeds. In mixed breed cows, higher than normal calcium concentrations were observed in downer cow syndrome (25.25 ± 8.47) and dystocia (85.50 ± 8.46) cases. It was also observed that cholesterol concentrations were significantly low in abortion (2.52 ± 0.79), retained placenta (3.18 ± 0.61) and vaginal prolapse (2.37 ± 0.97) cases in Afrikaner cows. The study showed that Brahman (43.1%) and Afrikaner (43.1%) breeds were mostly affected by downer cow syndrome. Additionally, the occurrences of downer cow syndrome (53.9%) and abortions (60%) were mostly observed in cows of 1-3 years, in second and first parities, respectively. This study proves that concentrations of calcium, urea or blood urea nitrogen (BUN), magnesium and cholesterol are significantly altered in incidences of reproductive conditions in cows of different breeds. It is also shown that serum biochemistry is affected by reproductive conditions in cows of different ages and parity. This data serves as a tool that could be used to enhance research in animal production and reproduction.

On each day of feeding on susceptible calves, salivary glands obtained from groups of adult ticks that transmitted Anaplasma marginale were examined for A marginale colonies by use of light microscopy and transmission electron microscopy. On day 8 of feeding, salivary glands were examined, using fluorescein-labeled antibody and methyl green-pyronine stain. Use of fluorescein-labeled antibody consistently revealed small numbers of fluorescent foci in salivary gland acinar cells obtained from ticks that had fed for 8 days. Colonies of A marginale were seen by transmission electron microscopy only in salivary gland acini of male ticks; these colonies could not be identified, using light microscopy, in companion 1-micron plastic sections stained with Mallory stain. Methyl green-pyronine stain, used commonly to detect theilerial parasites in tick salivary glands, did not differentiate A marginale from cytoplasmic inclusions normally found in salivary gland acinar cells.

The Malaysian Pangolin (Manis javanica) is an endangered species,&#xD;but is widely hunted for its medicinal value in body parts. A total of sixteen pangolins were screened for blood protozoa and six&#xD;pangolins were confi rmed to be positive for eperythrozoonosis infection based on morphology from blood smears stained with 8% Giemsa. The causative organism, Eperythrozoon sp., with a size of 0.3 μm were observed under a compound microscope at 100× magnification on the surface of red blood cells as blue coloured dots. This is the fi rst report of Eperythrozoon infection from pangolins in Malaysia. Further identifi cation using polymerase chain reaction (PCR) is necessary to confi rm E. ovis or wenyonii,&#xD;which is uncultivatable in artifi cial media.
