Laparoscopy is a growing field in veterinary medicine, although guidelines are lacking. The objective of this study was to evaluate the pressure–volume curve during capnoperitoneum in cats. A total of 59 female cats were scheduled for routine laparoscopy. Pressure and volume data were recorded and processed, and the yield point of the curve was calculated using a method based on a capacitor discharging function. For the remaining 40 cats, a linear-like pressure–volume curve was observed until a yield point with a mean cutoff pressure (COP) of 6.44 ± 1.7 mmHg (SD) (range, 2.72–13.00 mmHg) and a mean cutoff volume (COV) of 387 ± 144.35 mL (SD) (range, 178.84–968.43 mL) was reached. The mean mL/kg CO2 value in cats was 208 ± 34.69 mL/kg (range, 100.00–288.46 mL/kg). The COV correlated with COP and body weight but not with body condition score (BCS). COP correlated only with the COV. This study suggests that feline patients have a pressure–volume curve similar to that of canine patients, and the same pressure limit recommendations can be used for both species. After a yield point of 6.44 mmHg is reached, the increment in volume decreases exponentially as the intra-abdominal pressure (IAP) increases.

Some reproductive parameters of one-year-old 20 of each Red Sokoto and Kano Brown bucks were investigated. For the Red Sokoto and Kano Brown breeds of bucks, the mean (±S.E.) body weight, body condition score, scrotal circumference, testes weight, testes volume, epididymal length, epididymal volume, epididymal weight, testes sperm and epididymal sperm were 13.84± 0.54 vs 11.69 ± 0.35kg, 2.15±0.08 vs 2.10± 0.07, 19.83± 0.36 vs 18.27± 0.49cm, 36.41± 1.89 vs 29.70±1.98g, 35.63± 1.87 vs 29.48± 1.9ml, 10.67±0.20 vs 9.66± 0.25cm, 6.16± 0.23 vs 5.44±0.31ml 6.46± 0.24 vs 5.53± 0.34g, 0.24± 0.02 vs 0.16± 0.01 x 109 and 2.47± 0.16 vs 1.59± 0.16 x 109 respectively, and were significantly different between the breeds. The percentage epididymal segments mass and sperm were also depicted. There were highly significant correlations between many of the reproductive parameters in both breeds. The Red Sokoto bucks seem more adapted than the Kano Brown in terms of their reproductive make-up.

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.

This study was carried out to document the pelvic and testicular biometric characteristics of Sahel goats. Record of body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference were obtained from 400 male and 600 female Sahel goats. All the goats were approximately 1.5 years old and weighing 14 to 18 kg, with body condition score of 3 or 4 (scale of 1-5). The mean bodyweight of Sahel bucks was 15.12 ± 1.10 kg while that of Sahel does was 13.22 ± 1.12 kg, height at withers in bucks and does were 52.22 ± 1.20 cm, and 48.13 ± 1.23 cm respectively. The scrotal length and circumference in Sahel bucks were 11.39 ± 1.12 cm and 17.95 ± 1.21 cm respectively. The external pelvic circumference in Sahel does was 55.13 ± 1.16 cm. There was significant (P<0.05) positive correlation between the body weight and body condition score in bucks (r=0.52) and in does (r=0.42). It was observed that there was weak but positive correlation between the body weight and height at withers (r=0.34), in bucks and in does (r=0.25; P <0.5). A low but significant positive correlation was found between the body weight and scrotal circumference r=0.28, (P<0.05) in bucks. There was a highsignificant positive correlation between the scrotal length and scrotal circumference r=0.66, (P <0.05).  The external pelvic circumference in Sahel does was also significantly positively correlated with body weight r=0.40, (P<0.05) and with the body condition score r= 0.33, (P<0.05). In conclusion, the body weight, body condition score, height at withers, scrotal length, scrotal circumference and external pelvic circumference of Sahel goats in Maiduguri were successfully determined, these parameters studied might serve as a bases for determining the breeding soundness of Sahel goats.

Organic dairy cows were used to evaluate the effect of two organic pasture production systems (temperate grass species and warm-season annual grasses and cool-season annuals compared with temperate grasses only) across two grazing seasons (May to October of 2014 and 2015) on milk production, milk components (fat, protein, milk urea nitrogen (MUN), somatic cell score (SCS)), body weight, body condition score (BCS), and activity and rumination (min/day). Cows were assigned to two pasture systems across the grazing season at an organic research dairy in Morris, Minnesota. Pasture System 1 was cool-season perennials (CSP) and Pasture System 2 was a combination of System 1 and warm-season grasses and cool-season annuals. System 1 and System 2 cows had similar milk production (14.7 and 14.8 kg d−1), fat percentage (3.92% vs. 3.80%), protein percentage (3.21% vs. 3.17%), MUN (12.5 and 11.5 mg dL−1), and SCS (4.05 and 4.07), respectively. Cows in System 1 had greater daily rumination (530 min/day) compared to cows in System 2 (470 min/day). In summary, warm-season annual grasses may be incorporated into grazing systems for pastured dairy cattle.

The prevalence of feline obesity is influenced by numerous factors, including inactivity and overconsumption of food. The objective of the present study was to evaluate the effect of feeding frequency on physical activity in adult cats. A total of twelve healthy adult cats were used in a cross-over study consisting of 32 d. In each of the two periods, six cats were fed either two meals or four meals daily. Throughout the study, cats were fed the same diet at amounts to maintain body weight and body condition score. Cats were individually housed 4 h/d at each scheduled feeding time, while for the other 20 h, cats were group-housed to allow for voluntary physical activity in the room with a 16 h light–8 h dark cycle. Voluntary activity levels were evaluated using Actical activity collars for seven consecutive days in each period. Daily average activity level for two-meal-fed cats (20·04 (sem 2·19), activity counts/epoch (15 s)) was not different from four-meal-fed cats (20·14 (sem 2·15), activity counts/epoch (15 s); P>0·05). In conclusion, when group-housed cats are fed to maintain their body weight and body condition score, varied feeding frequency between twice and four times daily may not affect activity levels.

Abstract Context.—Polycythemia describes an increased proportion of red blood cells in the peripheral blood. In absolute polycythemia, there is increased red cell mass (RCM) with normal plasma volume, in contrast with apparent polycythemia, in which there is increased or normal RCM and decreased plasma volume. In order to deliver the appropriate treatment it is necessary to differentiate between the two. Objective.—A retrospective analysis of RCM and plasma volume data are presented, with special attention to different methods of RCM interpretation. Design.—The measurements of RCM and plasma volume in 64 patients were compared with the venous and whole-body packed cell volume, and the incidence of absolute and apparent polycythemia was determined for increasing hematocrit levels. Measurements of RCM and plasma volume were performed using chromium 51–labeled red cells and iodine 125–labeled albumin, respectively. The measured RCM of each patient was expressed as a percentage of the mean expected RCM and was also defined as being within or outside the range of 2 SD of the mean. The results were also expressed in the traditional manner of mL/kg body weight. Results.—Twenty-one patients (13 women and 8 men) had absolute polycythemia. None of them had an increased plasma volume beyond 2 SD of the mean. When expressed according to the criteria of mL/kg body weight, 17 of the 21 patients had abnormally increased RCM, but 4 patients (19%) had a normal RCM value. Twenty-eight patients had apparent polycythemia. The remaining 15 patients had normal RCM and plasma volume. Conclusions.—The measurement of RCM and plasma volume is a simple and necessary procedure in the evaluation of polycythemia. In obese patients, the expression of RCM in mL/kg body weight lacks precision, considering that adipose tissue is hypovascular. The results of RCM are best described as being within or beyond 2 SD of the mean value.
