Effect of Body Condition Score at Calving on Postpartum Performance of Murrah Buffaloes

Background: Body condition score (BCS) system is a subjective method to assess the body fat reserves particularly over the bony prominences like back and pelvic region. It is based on evaluation of the outer appearance of the animal that interacts with its body fat reserves and therefore is directly influenced by energy balance. Studies on the relationship between BCS and postpartum performance were meager in buffaloes. Hence, the present work was carried out to study the relationship between BCS at calving and postpartum performance in Murrah buffaloes. Methods: The effect of body condition score at calving (BCSc) on the postpartum performance was studied in 24 Murrah buffaloes grouped based on BCS, maintained at Buffalo Research Station during 2018-19. Result: The study showed that buffaloes of BCSc above 3.5 with significantly (P less than 0.01) higher body weights showed better reproductive performance compared to buffaloes of BCSc groups below 3.5 with less body weights. The prepartum and weekly postpartum changes in BCS studied showed that the buffaloes gained a BCS of 0.57 from 3 months prepartum to one week prepartum, lost 0.17 BCS due to calving, further showed a decline in BCS up to 9 weeks of postpartum and then started regaining BCS gradually until 18 weeks postpartum. The mean LBCS over the period of 18 weeks postpartum was comparatively higher (0.75±0.05) than BCS restored in the early lactation which was shown as GBCS (0.34±0.02). Buffaloes of BCSc group 3.5-3.99 showed the best reproduction performance among the four BCSc groups with less postpartum estrus period (46.66 days), service period (58.83 days), number of service per conception (1.50) and high rate of 1st service conception (66.66%).

Phenotypic characteristics and Gene Frequency of the Banyo Gudali zebu (Bos indicus) variety in the high Guinean Savannah zone of Cameroon

This study is aimed at evaluating the phenptypic and genetic diversity of local cattle breeds in Cameroon. To this end, biometric data were collected randomly in six (6) localities of the Mayo-Banyo Division, on a sample of 321 adult Banyo Gudali zebu cattle (234 cows and 87 bulls) aged between 6 and 16 years and having a body condition score varying from 2 to 4. Results reveal a variability of the coat color i.e., 19,00% white coat and its derivatives (speckled, stoat, grey, truiture); 9.99% black coat and its derivatives (black list and black piebald); 18.06% piebald (4.67% black piebald and 13.39 red piebald); 52.94% red and its derivatives (red piebald and red list). The single-colored coats are less represented (38.94%)compared to double-colored coats (61.06%). The frequency of alleles S+, D, ED, Aa, E+, s, A+, e and P are respectively 0.315; 0.201; 0.140; 0.267; 0.859; 0.685; 0.733; 0.386 and 1.000. There is a predominance of white-black horns (50.2%) over grey horns (42.4%). This population is characterized by long hairs, straight-edged ears oriented laterally and with humps occupying a cervico-thoracic position. The facial and back profiles are straight. The neck has a horizontal curved profile, the rump with a low set tail. Crescent shaped horns predominate (73,5%) followed by the horns in low lyre (15,9%) with the other shapes (stump, lateral pointed tip, crown and asymmetrical deformed right or left) being the least represented. The raised horns (92.5%) are predominant. Erect and moderate humps (86.6%) are dominant over drooping ones (13.4%).

Appetite Stimulant and Anti-Emetic Effect of Mirtazapine Transdermal Ointment in Cats Affected by Lymphoma Following Chemotherapy Administration: A Multi-Centre Retrospective Study

In humans, mirtazapine can prevent chemotherapy-induced nausea and vomiting (CINV) and improve cancer patients’ quality of life (QoL). This drug is being increasingly used as an appetite stimulant in cats. The hypothesis of this retrospective study was that mirtazapine could reduce the incidence of CINV and weight loss in feline patients affected by lymphoma. The objectives were to report the use of mirtazapine transdermal ointment and assess the incidence of gastrointestinal (GI) toxicity and weight loss in cats diagnosed with lymphoma and receiving chemotherapy. Transdermal mirtazapine was topically administered to the inner surface of the pinna (2 mg/cat/daily) for 14 days following chemotherapy administration. Data recorded from 20 patients were collected. Different grades of GI toxicity were shown in 8/20 (40%) patients. Body weight (BW), body condition score (BCS), and muscle condition score (MCS) improved in 12/20 (60%), 6/20 (30%), and 2/20 (10%) cats, respectively. Mirtazapine-induced adverse events (AEs) occurred in 4/20 (20%) cats and did not require mirtazapine discontinuation. Substantial weight loss was not encountered, suggesting that patients had an adequate food intake after chemotherapy administration. Transdermal mirtazapine ointment was considered safe and well tolerated.

The effects of differing nutritional levels and body condition score on scrotal circumference, motility, and morphology of bovine sperm

Bulls often experience various levels of nutrient availability throughout the year. Nutritional management is a critical factor on overall ejaculate composition and the ability to get females pregnant. We hypothesized that differing nutritional levels and body condition score (BCS) affects reproductive fertility parameters in bulls. Mature Angus bulls (n = 11) were individually housed and randomly assigned to one of two dietary regimens: 1) over-fed (n = 5) or 2) restricted (n = 6). Bulls were fed the same ration at different volumes to achieve desired effects resulting in 8 individual treatments: gain to an over-fed body condition score ([BCS]; GO), gain after nutrient restriction (GR), loss after an over-fed BCS (LO), loss from nutrient restriction (LR), maintenance at ideal adiposity (BCS = 6) after overfeeding (IMO), maintenance at ideal adiposity after nutrient restriction (IMR), maintenance at an over-fed BCS (BCS = 8; MO), and maintenance at a restricted BCS (BCS = 4; MR). Body weight (BW) and BCS were recorded every two weeks to monitor bull weight and BCS changes. Scrotal circumference was measured every 28 d. Body fat and sperm motility and morphology were evaluated every 84 d. Scrotal circumference, motility, and morphology were normalized to the initial value of each bull. Thus, allowing the individual bull to serve as a control. Statistical analyses were conducted with PROC GLIMMIX of SAS as a complete randomized design to determine if treatment influenced BW, BCS, scrotal circumference, motility, morphology, and adipose thickness. Scrotal circumference (P < 0.001) had the least amount of deviation from initial during the LR (0.29 ± 0.44) treatment and the greatest during the MO (3.06 ± 0.44), LO (2.28 ± 0.44), MR (2.43 ± 0.44), GR (3.03 ± 0.44) and IMR (2.91 ± 0.44) treatments. Sperm motility was not affected by nutritional treatments (P = 0.55). Both head and total defects of sperm differed (P = 0.02) due to nutritional treatments. Increased head abnormalities occurred during the LO (37.60 ± 8.61) treatment, with no differences between the other treatments. Total defects increased during the LO (43.80 ± 9.55) treatment with similar increases in bulls during the GR (29.40 ± 9.55) and IMR (35.60 ± 9.55) treatments. In conclusion, male fertility was impacted when a deviation from a BCS of 6 occurred which could be detrimental to reproductive and beef production efficiency.

Metabolic variables of obese dogs with insulin resistance supplemented with yeast beta-glucan

Background Obesity is one of the most common nutritional disorders in dogs and cats and is related to the development metabolic comorbidities. Weight loss is the recommended treatment, but success is difficult due to the poor satiety control. Yeast beta-glucans are known as biological modifiers because of their innumerable functions reported in studies with mice and humans, but only one study with dogs was found. This study aimed to evaluate the effects of a diet supplemented with 0.1% beta-glucan on glucose, lipid homeostasis, inflammatory cytokines and satiety parameters in obese dogs. Fourteen dogs composed three experimental groups: Obese group (OG) with seven dogs with body condition score (BCS) 8 or 9; Lean group (LG) included seven non-obese dogs with a BCS of 5; and Supplemented Obese group (SOG) was the OG dogs after 90 days of consumption of the experimental diet. Results Compared to OG, SOG had lower plasma basal glycemic values (p = 0.05) and reduced serum cholesterol and triglyceride levels. TNF-α was lower in SOG than in OG (p = 0.05), and GLP-1 was increased in SOG compared to OG and LG (p = 0.02). Conclusion These results are novel and important for recognizing the possibility of using beta-glucan in obesity prevention and treatment.

Interaction between the body condition score, gait, hindlimb conformation, and claw conformation in dairy cows in Aydin, Turkey

ABSTRACT: Breeding strategies aim to reduce lameness in dairies by using predictor traits to increase the selection of dairy cows. This study enhanced the present knowledge about association between the claw conformations (CC), hindlimb conformation (HiLC), gait, and body condition score (BCS) in dairy cows. A total of 166 lactating Holstein cows were enrolled in the study and scored for BCS, CC, HiLC, and gait. The abnormal HiLC group was statistically significant (P<0.001) to have more abnormal CC. Hock in (Hin) cows showed significance (P<0.001) with CC abnormalities. Cows with abnormal gait have less abnormal claw and limb conformation than normal cows (P=0.032). Lactation number (P=0.036) and abnormal HiLC (P<0.001) were significantly increased risk for CC. The present results might be useful for claw and hindlimb conformations, and breeding strategies of the herd.
