Canine medial patellar luxation (MPL) is a very common orthopedic disease in small animals. Because the pathophysiology of this disease involves various pathways, the surgical techniques and results vary according to the veterinarian. Further, the landmark for block recession is not completely clear. We retrospectively evaluated 75 dogs (107 limbs) with MPL in whom our landmark for block recession was used from July 2008 to May 2013. Information regarding the breed, age, sex, body weight, body condition score (BCS), lateral <em>vs</em> bilateral, pre-operative grading, surgical techniques, removal of implants, concomitance with anterior cruciate ligament (ACL) rupture, re-luxation, re-operation, and rehabilitation was obtained from the medical records. The breeds were as follows: Chihuahua (n=23), Pomeranian (n=12), Yorkshire Terrier (n=9), and so on. The study group consisted of 33 males (castrated n=13) and 42 females (spayed n=21). The median age was 53.3±35.9 months (32-146 months); 13 cases were less than 12 months of age (17.3%). The pre-surgical BCSs were as follows: 1 (n=0), 2 (n=20), 3 (n=24), 4 (n=24) and 5 (n=7). The body weight was 4.51±3.48 kg (1.34-23.0 kg); 71 cases (94.7%) were less than 10 kg. The MPL grades (each limb) were G1 (n=1), G2 (n=18), G3 (n=78), and G4 (n=10); 32 cases were bilateral and 43 cases were unilateral (right n=27; left n=16). The specific surgical procedure (distal femoral osteotomy) was 3 stifles in Chihuahuas. Concurrent with ACL rupture was 16/107 stifles (15.0%) corrected with the over-the-top method or the extracapsular method in Papillons (5/6), Chihuahuas (5/23), and so on. The occurrences of re-luxation and re-operation were 3 out of 107 stifles (2.8%) and 0%, respectively. In this retrospective study, we present a potentially good surgical landmark for block recession of MPL in dogs.

Introduction. The most common injuries of the knee joint are injuries of the anterior cruciate ligament. The golden standard in reconstruction of this ligament is graft bone - patellar tendon - bone. Knowing the morphometric characteristics of these ligaments is crucial for anterior cruciate ligament reconstruction. This study was aimed at determining morphometric characteristics of the patellar tendon in vivo, measured intraoperatively, and at defining the correlation between the obtained values and body weight, height, gender and sport activity among different groups of athletes. Material and Methods. This study included 184 patients suffering from anterior cruciate ligament injuries who were admitted to the Clinical Center of Vojvodina, Department of Orthopedics and Traumatology. Results. The patellar tendon width ranged from 28 mm to 43 mm, averaging at 32.02 mm. The length of the patellar tendon ranged from 35 mm to 62 mm, averaging at 46.34 mm. The thickness of the patellar tendon ranged from 3 mm to 6 mm, averaging at 3.78 mm. The measured results were positively and statistically relevant with the body mass, height and body mass index. Discussion and Conclusion. The patellar tendon was thicker, longer and wider in persons with higher values of body weight and height. Men have statistically longer, thicker and wider patellar tendon than women. There was no statistically significant difference between morphometric characteristics of the patellar tendon among professional athletes and recreational athletes, neither was there one in the obtained geometric data of the patellar tendon among tested groups of professional athletes.

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.

Abstract Background The main objectives of this study were to evaluate the accuracy of different body weight formulas for estimating body weight of Icelandic and Warmblood horses, as well as to assess the associations between the variables cresty neck score, body condition score, and plasma concentrations of leptin, insulin and cortisol. A total of 81 adult (≥ 4 years of age) horses (43 Icelandic and 38 Warmblood horses) was included in this study. The following morphological measurements were collected by two examiners simultaneously; body weight; height at withers; neck length; 0.5 neck length; neck circumference; umbilical circumference, two different heart girths, as well as two different body length measurements. The horse’s body weights were measured on a weight scale, and cresty neck scores were rated along with body condition scores using both the 0 to 5 and the 1 to 9 systems. Results In general, the concordance correlation coefficient was high for most formulas, but the mean bias and slope bias deviations varied between formulas. Some simple formulas using only heart girth, or heart girth and length can be used to estimate body weight of Icelandic and Warmblood horses as good as more complex formulas using four morphometric measurements. Plasma concentrations of leptin and insulin were higher (P < 0.001) for the Icelandic than the Warmblood horses, probably reflecting higher body fat content as suggested by the differences in body condition score. Conclusions Body weight formulas only give an estimate of body weight and not a completely correct determination. Some simple and more complex formulas can be used for Icelandic horses even though they are not developed for this breed. Complex formulas using four morphometric measurements were accurate, but simple formulas using only heart girth, or heart girth and length can be used to estimate body weight and thereby be applied to weight tapes and used to estimate the body weight of both Icelandic and Warmblood horses.

Background: Injuries of posterior lateral meniscus root (PLMR) are related to an acute trauma mechanism, which is commonly associated with anterior cruciate ligament (ACL) rupture. Many biomechanical studies have exposed the importance of the integrity of PLMR. There are several surgical techniques for its treatment, but is still controversial about which is the most appropriate, especially for combined injuries. Objective: To describe the clinical outcomes of patients with a surgical treatment of PLMR tear combined with ACL rupture Methods: Prospective case series. With patients who undergone repair of PLMR tears with ACL rupture, from 2016 to 2017 in a specialized hospital in Medellín city. Clinical evaluation it was determinate with Lysholm and IKDC (International Knee Documentation Committee) scores, before and one year after the surgical procedure. The paired sample t-test was applied to compare the results of the scores. Results: Six patients with acute lesion of PLMR tear combined with ACL rupture received treatment with a variation in the transtibial fixation of the PLMR surgical technique. Statistically significant differences were found when comparing the two scores before and after surgery (p=<0.05). In addition, no additional surgical interventions were performed in the follow-up time. Conclusion: The combined surgical treatment of PLMR and ACL injuries can be performed safely. This surgical technique provided an improvement in function, pain and activity level, which may help to delay the progression of osteoarthritis of the knee.

A total of 539 pure-bred and seventy-five cats without a pedigree were weighed and scored at cat shows or in veterinary surgeries. Data from normal-weight cats with a body condition score (BCS) of 5 (ideal) were only used. Breeds were grouped into five classes. For female cats, the mean weight for these groups were as follows: very light (2·8 kg); light (3·2 kg); medium (3·5 kg); large (4·0 kg); giant (4·9) kg. For male cats, the corresponding values were 3·6, 4·2, 4·3, 5·1 and 6·1 kg. Siamese/Oriental Shorthair were identified as a very light breed, the Norwegian Forest and the Siberian Cat as a large breed and the Maine Coon as a giant breed. Males and females of the same breed did not always belong to the same class. In some breeds, individuals of the same sex were found in two different classes. The percentage of intact overweight cats (BCS >5) was low (7 % of intact males, 3 % of intact females). Incidence of overweight in neutered cats was 50 % in males and 38 % in females. Among pedigreed cats, there were differences in the incidence of overweight in neutered cats: high in Norwegian Forest Cats (males 75 %, females 50 %) and low in Siamese/Oriental Shorthair Cats (males 25 %, females 1 %). Cats with a BCS of 6, 7 and 8 had on average 120, 154 and 214 % of the normal weight of their breed, respectively.

Background: Coatis (Nasua nasua) have easy interaction with man, besides being sociable and curious animals. The proximity to urbanized areas encourages them to intake food from anthropogenic sources, and it can change their eating habits and make them prone to obesity. The body condition evaluates the animals’ energetic status and measures variations in their body fat reserves. There are direct-invasive methods and indirect methods that rely on size and body mass to evaluate the body condition, like body condition score and body mass index. Thus, the aim of the present study was to assess different methods to determine the body condition of wild coatis (Nasua nasua) living in urban areas.Materials, Methods & Results: Sixteen (16) wild coatis (Nasua nasua), nine females and seven males, were captured at Faculty of Veterinary Medicine and Animal Science (FMVZ) of São Paulo State University, Botucatu, in pitfalls. The animals were anesthetized with ketamine and midazolam and subjected to biometric evaluation after physical exams proved normal. The following variables were analyzed: body weight, body condition score (BCS) based on the five-point scale for dogs, thoracic and abdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus. Two body mass index (BMI) were calculated from these data, one was based on dogs (BMI1) and another one on cats (BMI2), as well as the body fat percentage (%BF). Results showed that 25% of the assessed coatis were overweight. Body weight, thoracic and abdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus were significantly higher in males than in females and the other assessed parameters did not present differences between sexes. The correlation between fat percentage and body weight was significant, and that between fat percentage and BCS was not. There was closer correlation between BMI2 and body weight, and BCS, than between BMI1 and these two parameters.Discussion: Anthropogenic interactions could change the body condition of these animals and make them prone to obesity, since their body condition scores were altered. With regard to the nutritional body condition, although males were bigger than females, the measures did not show significant differences between them. Results of this parameter varied in different studies with coatis, some studies have shown that males have body mass 1/3 higher than that of females and others have not recorded any difference between sexes. Fat percentage estimated through the metrics used in cats is not a good method when it is applied alone in body condition evaluations. A study that has correlated body mass, body condition score, body fat estimates, body mass index and abdominal circumference recorded positive results between these two evaluation methods. Such finding corroborated with the present study, but it was differed from it in abdominal circumference, which did not correlate to the two body mass indices and to body fat percentage. Therefore, it is possible saying that there is biometric difference between male and female coatis. The body condition score adopted for dogs was efficient for coatis (Nasua nasua), as well as the body mass index used for dogs and cats – the one used for cats was even more efficient. The proximity wild coatis (Nasua nasua) have to humans could change the body condition of these animals and make them prone to obesity.

The body weight and testicular and epididymal parameters of Afar, Long-eared Somali (LES), and Woyto-Guji (WG) breeds of goat were investigated. A total of 405 randomly selected bucks of Afar (n=135), Long-eared Somali (n=135), and Woyto-Guji (n=135) were included in this study. The overall mean scrotal circumference (SC), testicular volume (TV), testicular length (TL), testicular weight (TW), body weight (BW), epididymal weight (EW), body condition score, and testicular diameter (TD) measurements in all bucks were 20.8±1.94 cm, 68.1±6.18, 4.96±0.79 cm, 70.0±5.66 g, 22.1±2.98 Kg, 9.09±1.88 g, 2.55±0.68, and 4.28±0.45 cm, respectively. Significant (p<0.05) breed differences in SC, TD, TL, TW, BW, EW, and TV were recorded. Long-eared Somali (LES) breed was heaviest and Afar breed was the lightest and Woyto-Guji (WG) had the average BW. In all breeds, the parameters were positively correlated. In Afar breed, the TW had a significant correlation with BW (r=0.90) and SC (r=0.65). In LES BW was highly correlated with TD (r=0.96) and TL (r=0.96). In WG, TW was significantly correlated with TD (r=0.94), EW (r=0.90), TL (r=0.89), and BW (r=0.82). In multiple regression analysis the linear combinations of BCS, SC, and BW significantly predicted TW, TL, TV, TD, and EW in all breeds. In conclusion, Long-eared Somali breed displayed greater BW and scrotal and testicular traits.

The aim of this study was to evaluate the effect of different suckling regimens on body condition and interval from lambing to onset of the cyclic ovarian activity in Santa Inês ewes. Thirty-two ewes were allocated to blocks according to parity, number of lambs, and body weight and submitted to 3 treatments: continuous suckling (n = 11 ewes, 13 lambs), controlled suckling (n = 10 ewes, 14 lambs) with 2 suckling periods per day for 1 h from Day 10 postpartum (pp), or early weaning (n = 11 ewes, 14 lambs) with total separation of the lambs from Day 10 pp. The animals were evaluated in the interval from Day 12 pp to first estrus or to Day 60 pp. Dry matter intake was evaluated daily. The body weight of ewes and lambs and body condition score (scale 1 = thin and 5 = fat) of ewes were evaluated at lambing and at every 6 days after. Lambs were weighed at weaning. Estrus was monitored twice daily with a teaser ram. Blood samples for progesterone measurement were collected and ovarian ultrasonography was done at intervals of 3 days from Day 12 pp to first estrus or to Day 60 pp. Dry matter intake was analyzed over time, considering 9 periods, with PROC MIXED of SAS (2008; SAS Institute Inc., Cary, NC, USA). Body weight, body condition score, interval from lambing to first ovulation, and weaning weight were analyzed using the GLM procedure, ANOVA, and an F-test. The intervals from lambing to first estrus and to follicles with a diameter ≥5 mm were analyzed considering a Poisson distribution and the percentage of estrus manifestation was analyzed considering a Bernoulli distribution, by generalized linear models, using PROC GENMOD. The dry matter intake did not differ (P > 0.05) among treatments (2.3 ± 0.1, 2.2 ± 0.0, and 1.6 ± 0.0 kg day–1), but it differed over time (P < 0.05). The body weight gain (3.3 ± 1.0, 3.0 ± 0.9, and 2.1 ± 1.4 kg), body condition score gain (0.2 ± 0.1, 0.2 ± 0.1, and 0.2 ± 0.1), percentage of estrus manifestation (63.6, 50.0, and 54.5%), interval from lambing to first estrus (45.0 ± 3.9, 44.0 ± 7.2, and 32.3 ± 5.4 days), follicle with a diameter ≥5 mm (31.0 ± 3.3, 33.9 ± 3.0, and 34.9 ± 4.5 days), and ovulation (38.0 ± 3.6, 35.6 ± 3.9, and 26.5 ± 3.2 days) did not differ among treatments (P > 0.05). The dry matter intake was correlated with body weight in ewes that were submitted to continuous suckling (r = 0.7; P < 0.01) and controlled suckling (r = 0.6; P < 0.01), but not in those submitted to early weaning (r = 0.2; P > 0.05). The body condition score was correlated with body weight in ewes submitted to continuous suckling (r = 0.8; P < 0.01), controlled suckling (r = 0.4; P < 0.01), and early weaning (r = 0.5; P < 0.01), and with dry matter intake in those submitted to continuous suckling (r = 0.4; P < 0.01). Weaning weight was lower (P < 0.05) in lambs subjected to early weaning (19.0 ± 1.0, 18.3 ± 1.0, and 15.2 ± 0.6 kg), but their health was not compromised. Continuous suckling did not delay the return to postpartum cyclic ovarian activity and did not influence the postpartum body condition of Santa Inês ewes and should be used by producers.

The Relationship

This study examined the relationship of body condition and chewing time (CT) with body weight (BW), the level of cocaine-and amphetamine-regulated transcript (CART), leptin and energy metabolites in cows until reaching the lactation peak. The results showed the greatest loss of BW between days 11 and 45 of lactation and a decrease in the body condition score (BCS) until day 75. Chewing time showed an increase from day 45 with the highest values after lactation peak. The CART and leptin concentrations demonstrate a reduction of both indices (P < 0.05) between days 11 and 75. The function of leptin as a factor positively correlating with BW and BCS was found. In the heaviest individuals and those with higher BCS, the blood leptin levels were higher. The results of beta-hydroxybutyrate (BHBA) indicate that cows with the lowest BCS had the most intensive energy transformation. This led to a higher BHBA concentration compared to the cows with high BCS (P < 0.05). The obtained results show that CART was most strongly negatively associated with CT (P < 0.05). For leptin, the tendency was the opposite and the correlation with CT was not significant. The results suggest that CT may be stronger regulated by CART, which has anorectic properties, than by appetite inhibiting leptin. Significant decrease of body condition during lactation is a great problem for dairy farmers. The explanation of the issue of the participation of CART and leptin in the regulation of body’s energy homeostasis may therefore be of importance for milk production.

Extracapsular technique with lateral fabellar suture (LFS) is one of the commonest surgical techniques for canine cranial cruciate ligament (CRCL) rupture. Among LFS methods, parallel double holes in the tibia are the most effective for the repair of canine stifle joint. The aim of this study was to evaluate the effectiveness of two-hole LFS for canine CRCL rupture. We retrospectively evaluated the outcome of canine CRCL rupture treated with two-hole LFS technique performed by two surgeons from October 2011 to September 2013. Breeds included Beagle (n=5), Yorkshire terrier (n=5), German shepherd (n=4), and so on. Mean body weight was 14.0±11.6 kg (&gt;10 kg: n=16, &lt;10 kg: n=22). Body condition score (5 scales) was as follows: 1 (n=0), 2 (n=1), 3 (n=18), 4 (n=18), and 5 (n=1). There were 18 males [neutered (n=11)] and 20 females [spayed (n=12)]. Mean age was 83.4±44.8 months (&gt;12 months: n=35, &lt;12 months: n=3). The type of rupture was partial (n=17) and complete (n=21). The affected site was right (n=20), left (n=18), and bilateral (n=4). Rehabilitation after operation was needed in 8 cases. There were 12 cases of previous medial patellar luxation operation, and 6 cases of opposite site CRCL surgery. Start of weight bearing and resolution of extension function was on day 1 (n=30), day 2 (n=0), and after day 2 (n=8). There was no evidence of surgical site infection/inflammation in any cases. The results of this study showed that two-hole LFS is an easy and effective technique for the repair of canine CRCL.
