Residual feed intake (RFI) is a measure of feed (energy) requirements of individuals, relative to the population mean. Two groups, of ~120 Holstein-Friesian heifer calves (aged 6–9 months), which differed in efficiency by ~20%, were reared and mated. Liveweight and body condition score (BCS) were measured from 1 week pre-calving, for 16 weeks. Measurements were undertaken in 221, 59 and 104 of these animals as they entered their first (aged 2 years), second or third calving, respectively. The cattle were managed under conditions typical of commercial pastoral farming, and the objective was to measure effects of divergence for RFI on post-calving liveweight and BCS change, to indicate tissue mobilisation. The measurements made showed no difference between RFI selections for liveweight before the first (466 kg), second (535 kg) or third (569 kg) calving. Selection for divergent RFI did not affect liveweight at nadir (2–6 weeks post-calving), weight loss to nadir, or BCS at any time. Tissue mobilisation and re-synthesis is energetically inefficient, and although a greater post-calving loss from inefficient cf. efficient cows may have been anticipated, this was not supported by the similarity in liveweights, liveweight and BCS change in the selection lines for RFI.

Genetic Index

This study aimed to determine estimates of production efficiency among primiparous suckler cows of diverse genetic merit (GM) for the national Irish maternal index. Data from 82 heifers of diverse GM across two different replacement strategies (suckler (S) or dairy (D) sourced) were available. Milk yield, grass dry matter intake, cow BW and body condition score (BCS) were recorded. The maternal index had no significant effect on any parameters investigated, whereas S cows were 86 kg heavier in BW, had a 0.33 greater BCS and 0.6 UFL greater NEM requirement compared with D beef crossbred (F1) cows. The F1 produced 2.2 kg/day more milk and had greater lactation energy requirements (0.8 UFL) than S. The F1 produced 0.48 kg milk per 100 kg BW and 0.15 kg more milk per unit intake. An interaction between GM and cow origin (CO) showed that F1 low merit cows consumed an additional 1 kg DM than F1 high, and that S high merit cows produced 1.5 kg less milk than their S low counterparts resulting in a 0.5 UFL greater energy requirement for milk production for S low. The F1 high merit cows produced 0.12 kg more milk per unit intake than F1 low cows, whereas S low cows produced 0.12 kg less milk per unit intake than S high. The F1 low cows consumed 0.17 kg more DM per unit BW than F1 high. Thus, genetic selection for maternal traits has not resulted in differences in production efficiency traits, however CO differences were observed.

Abstract Alpine doelings (54; initial BW and age of 31.7±0.38 kg and 306±1.9 days, respectively) were used to evaluate relationships among body condition score (BCS), linear measures and associated body mass indices (BMI), and growth performance. Doelings were allocated to treatments with ad libitum intake of diets of 75% alfalfa or sericea lespedeza. The experiment was 12 wk with two 6-wk periods. Linear measures included height at the withers (Wither), length from the point of the shoulder to hook bone (Hook) and pin bone (Pin), and circumference from heart girth (Heart). There were 13 BMI, including BMI1–Wither (BW/Wither), BMI2–Hook (BW/Hook), BMI3–Pin (BW/Pin), BMI4-Heart (BW/Heart), BMI6-Wither×Hook (BW/(Wither×Hook)), BMI7-Wither×Pin (BW/(Wither×Pin)), BMI8-Heart×Hook (BW/(Heart×Hook)), and BMI9-Heart×Pin (BW/(Heart×Pin)), all in g/cm2. Correlation coefficients between BCS and Wither, Hook, Pin, and Heart were 0.14 (P = 0.155), 0.29 (P = 0.002), 0.21 (P = 0.030), and 0.38 (P < 0.001), respectively. Correlation coefficients of BCS were 0.39 (P < 0.001), 0.21 (P = 0.023), 0.32 (P = 0.001), 0.18 (P = 0.064), and 0.23 (P = 0.018) for BW, ADG, and DM intake in g/d, % BW, and g/kg BW0.75, respectively, with nonsignificant r for residual feed intake and ADG:DM intake. Higher r were observed between BMI and performance measures. Correlation coefficients were 0.71, 0.58, 0.66, 0.69, 0.78, 0.67, and 0.812 between BMI1-Wither, BMI3-Pin, BMI4-Heart, BMI6-Wither×Hook, BMI7-Wither×Pin, BMI8-Heart×Hook, and BMI9-Heart×Pin and BW; 0.36, 0.45, 0.42, 0.34, and 0.42 for BMI2-Hook, BMI3-Pin, BMI6-Wither×Hook, BMI7-Wither×Pin, BMI8-Heart×Hook, and BMI9-Heart×Pin and ADG; and 0.49, 0.56, 0.47, 0.63, and 0.58 for BMI1-Wither, BMI3-Pin, BMI6-Wither×Hook, BMI7-Wither×Pin, and BMI9-Heart×Pin and DM intake, in g/d, respectively. The BMI were not related to residual feed intake, and there were some BMI with weak relationships to ADG:DM intake. In conclusion, due to stronger relationships between measures of performance of yearling Alpine doelings consuming a forage-based diet and BMI compared with BCS, future research should address other physiological states and productions conditions.

Peak Lactation

A significant factor in improving the performance of dairy cows is their physiological ability to correct a negative energy balance (NEB). This study, using Simmental (SIM) and Holstein-Friesian (HF) cows, aimed to assess changes in NEB (non-esterified fatty acid; body condition score; and C16:0, C18:0, and C18:1) and its effect on the metabolic efficiency of the liver (β-hydroxybutyrate and urea). The effects of NEB on daily yield, production at peak lactation and its duration, and changes in selected milk components were assessed during complete lactation. Up to peak lactation, the loss of the body condition score was similar in both breeds. Subsequently, SIM cows more efficiently restored their BCS. HF cows reached peak lactation faster and with a higher milk yield, but they were less able to correct NEB. During lactation, their non-esterified fatty acid, β-hydroxybutyrate, C16:0, C18:0, C18:1, and urea levels were persistently higher, which may indicate less efficient liver function during NEB. The dynamics of NEB were linked to levels of leptin, which has anorectic effects. Its content was usually higher in HF cows and during intensive lactogenesis. An effective response to NEB may be exploited to improve the production and nutritional properties of milk. In the long term, it may extend dairy cows’ productive life and increase lifetime yield.

Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a “normal” lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six “normal” lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P=0.02) lower (162.6 kJ/kg FFM/d) than that of the “normal” lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake34.5±1.5 g dry matter/kg body weight0.67compared to the GL cats (24.0±2.1 g dry matter/kg body weight0.67)(P=0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to “normal” lean cats were found.
