Repeatability for seminal traits and their phenotypic relationships with testes measurements and performance traits in Black Bengal bucks were estimated from a total of 116 repeated observations on 15 young Black Bengal bucks. Performance traits included age, body condition and body weight of bucks. Testes measurements were testes length, breadth and volume, and scrotal circumference, while seminal traits were ejaculate volume, semen density, mass activity, sperm motility, sperm concentration, total sperm per ejaculation and percent of normal sperm. High positive correlations (ranging from 0.81 to 0.90) were found between body weight and testes measurements. Semen volume and percent of normal sperm were positively correlated with age, body condition and body weight of bucks (ranging from 0.24 to 0.60). The testes measurements were strongly and positively correlated with semen volume and total sperm per ejaculation (ranging from 0.53 to 0.61), while the correlations between testes measurement and percent of normal sperm were moderate (ranging from 0.34 to 0.44). Among seminal traits, strong correlations were found between semen volume and total sperm per ejaculation (0.81) and, between mass activity and sperm motility (0.82). Repeatability of ejaculate volume was higher (r = 0.78) which indicated that selection or culling for semen ejaculate volume could be practiced from single or few observations. It could be concluded that bucks’ age, body weight and body condition along with testes volume should be considered as selection criteria for improving semen quality and semen production of breeding bucks.

Condition Score

Abstract Several factors influence the overall maintenance requirements of a mature beef cow including age, gain, lactation, pregnancy, and fleshing ability. However, limited research is available to distinguish what sets a hard-fleshing cow apart from an easy-fleshing cow. Cows that are hard-fleshing maintain a lower body condition score (BCS) throughout the year compared to easy-fleshing counterparts. The objectives of this experiment are to determine the differences in characteristics and production between cows classified as easy- vs. hard- fleshing. Characteristics of interest include feed intake, milk yield, milk composition, body weight changes, BCS changes, and other body composition measurements, as well as calf weaning weight. In this study, 24 spring-calving, mature Angus beef cows were classified as either hard-fleshing or easy-fleshing based on BCS and ultrasound measurements for back fat and rump fat. The intake study took place during the second trimester, cows were assigned to an easy- or hard-fleshing pen based on treatment where they remained for the entirety of the 45-day intake study. Each treatment was replicated three times in a completely randomized design. Milk data collection began one month after calving with monthly milkings from May-August. There were no differences (P = 0.9) in DMI, although hard-fleshing cows had greater DMI calculated on a metabolic body weight basis (P = 0.05). There was a trend (P = 0.12) for hard-fleshing cows to wean heavier calves, although there was no difference in mean milk yield (P = 0.44). Body condition score was positively correlated with protein and carbohydrate content of milk with easy-fleshing cows having greater contents of both (P = 0.02 and P < 0.01, respectively). Overall, an increase in BCS without an increase in DMI may be beneficial from a reproductive standpoint, though more research in this area is needed.

Body Condition Scoring

AbstractAfrican side-neck turtles (Pelomedusa subrufa and Pelusios castaneus) are popular in captivity, in many parts of the world. their natural tendency to accumulate body fat reserves may be a reason for many health issues. for keepers and veterinarians body condition scoring is an important tool in the process of management and care of the animals. therefore the main aim of the study was to formulate a single mathematic formula for allometric equations and simple body condition scoring method which can be used in juvenile, sub-adult and adult specimens of Pelomedusa subrufa and Pelusios castaneus. twelve healthy turtles (7 Pelomedusa subrufa and 5 Pelusios castaneus) – 4 males, 4 females and 4 immature were measured and weighed for 52 weeks (624 measurements). the obtained data were used to formulate equations of estimated body weight and compared to results of measurements of 73 turtles from private keepers. additionally, visual assessments of their body condition were made. The results showed that body weight is significantly (P=0.001) correlated with straight carapace length of turtles. in the assessed population of 73 captive Pelomedusidae kept as pets, no emaciated turtles were recorded, and 10% of them were underweight. In the case of 68% of the animals, body condition was identified as optimal, and in 15% and 7% as overweight and obese, respectively. The population of african side-neck turtles seems to be in quite good body condition. However, a high percentage of overweight and obese animals suggests the need for continuous monitoring of pet turtles for body condition.

A comparative assessment of the reproductive qualities of beef-cows of the Hereford and Kazakh white-headed breeds is given, depending on the Body Condition Scoring. In the scientific and economic experiment in three farms on 3 groups of cows of two breeds, the influence of Body Condition Scoring on the reproductive qualities of cows was studied. It was found that cows with a Body Condition Scoring of 6 points have a significantly shorter service period (by 10-13 days) and the interval between calving (by 6-9 days), with an increase in the duration of pregnancy by 2-4 days, compared with cows with a score of 3 points. The calf crop per 100 cows, in groups with 6 Body Condition Scoring points, was higher than in groups with 3 Body Condition Scoring points by 9.2, 8.3 and 5.1%.

Height Data

Intake and performance of 40 spring-calving cows with calves was investigated under a rotational grazing management system across three consecutive summers. A 19.2 ha pasture was divided into sixteen 1.2 ha fields with each field being further subdivided into eight 0.15 ha paddocks. Five cows with calves belonging to one of two breed groups (large vs. medium framed) and two body conditions (high vs. low) were randomly assigned to graze each of eight field pairs from May to October of each year. Paddocks not grazed by cow-calf pairs were grazed by yearling heifers or mechanically harvested as hay or silage. Grazing was managed by setting target sward heights for exit of each paddock at 8 to 10 cm and allowing a minimum of 25 to 30 d for regrowth. Paddocks were topclipped and fertilized with 34 kg ha−1 of nitrogen (N) immediately following the second grazing of each paddock. Sward surface height data were collected from 40 measurements taken immediately pre- and post-grazing in each paddock as well as during the regrowth period. Herbage biomass and quality was determined in year 1 by handclipping 10 quadrats (1.22 m × 0.15 m) from each paddock pre- and post-grazing and by clipping 7 similar quadrats from alternate paddocks in each of the other 2 yr. Average pre-grazing sward heights were 24.8, 30.3 and 28.1 cm, in years 1, 2 and 3, respectively. Herbage biomass available for grazing averaged 7.59, 10.62 and 11.04 tonnes DM ha−1 for years 1, 2 and 3, respectively. A positive linear (r = 00.93 P < 0.0001) relationship was established between sward height (cm) and herbage biomass (kg DM ha−1) across all 3 yr. Intake of dry matter (DM), crude protein (CP) and metabolizable energy (ME) was higher for both large- and medium-framed cow-calf pairs in year 3 than in the other 2 yr. Both large- and medium-framed cows lost (P < 0.05) body condition in years 1 and 2, but gained in year 3. Cows from the low body condition group gained (P < 0.05) more than those from the high group in years 2 and 3. Medium-framed calves gained more (P < 0.05) in year 3 than in years 1 and 2. Body condition of cows grazing a multi-species grass-legume pasture can be maintained if not improved provided seasonal variations in quality and quantity are minimized.

AbstractThe objective of the experiment was to test whether maintenance energy requirements of non-lactating, non-pregnant beef cows increased with body fatness. Twelve Charolais cows were initially fed to attain either lean or fat body condition. Subsequently, over a period of 66 days food allowances were regularly adjusted for zero live-weight change. For the following 76 days, lean and fat cows received either 400 or 553 kJ metabolizable energy (ME) per kg initial live weight 0·75 per day, respectively. Fat cows maintained their body weight and composition whereas lean cows lost 296 g body weight, 221 g lipid and 65 g protein daily. Calculated maintenance energy requirements averaged 516 and 536kJ ME per kg live weight 0·75 per day for lean and fat cows respectively but were not significantly affected by body fatness. Diet dry matter, organic matter, crude protein and energy apparent digestibilities but not acid-detergent fibre digestibility were significantly higher in fat animals.
