Abstract The study was conducted to evaluate the fattening performance of Arsi, Borana, Harar and HF-Crossbred bulls finished under similar feeding condition at the beef farm in Haramaya University. A total of 24 bulls with age categories of 2-3 and 4-5 years were used in the complete block design for the experiment. Total mixed ration was provided at 3% of their BW during experimental periods. The average daily weight gain of the four breeds range from 0.49 to 0.71 kg. Feed conversion efficiency also ranges from 0.11 – 0.15. Simple linear regression models were used to explore the relationship between live body weight change and change in BCS as well as seven linear body measurements for all age groups. An average change for a unite of body condition score was equivalent to 20.3, 20.61, 22.42 and 27.78kg for Borana, Arsi, Harar and HF-crossbred bulls respectively. BCS was significantly (P<0.01) influenced by breeds. There was a significant (P<0.05) breed by age interaction effect on the initial body condition score of the four breeds. There was a significant and positive strong association between change in BW and BCS. There was a significant and strong correlation between change in BW and change in Total topline, neck length, heart girth, flank circumference and rump length having correlation coefficient ranges (r = 0.57 to 0.97). Higher (P<0.01) net profit of 7,380.47 ETB per head was recorded by Borana bulls followed by Harar bulls, Arsi and HF Crossbred with net profit of 5,406.86, 5193.29 and 3,384.98 ETB per head respectively.

The effects of two levels of herbage allowance (HA, kg DM/kg liveweight (LW)) on forage mass and chemical composition, cow body condition score, cow LW, stocking rate, productive and reproductive responses were evaluated during two consecutive years. Eighty primiparous spring-calving beef cows were allocated to a completely randomised block design of two HA that had an annual average of 2.5 (low) and 4.0 kg DM/kg LW (high) from –150 to 195 days postpartum. The grazing system was continuous, and the put-and-take method was employed to adjust HA. At 86 ± 12 days postpartum, all cows were submitted to calf suckling restrictions with nose plates (12 days) and dietary flushing (2 kg/cow.day of whole-rice bran for 22 days), 6 days before bull introduction. Forage mass was affected by HA (P = 0.004) and year (P = 0.014); the high HA had a greater forage mass than the low HA (1474 vs 1212 ± 86 kg DM/ha; P < 0.05), and Year 2 had a greater forage mass than Year 1 (1545 vs 1134 ± 78 kg DM/ha; P < 0.05). Stocking rate was affected by HA and season (P = 0.0004) interaction. The stocking rate during autumn and spring was greater in low than high HA, and no differences were identified in winter and summer. The body condition score was improved in high HA during autumn and resulted in a greater winter (mid-gestation) body condition score than the low HA without differences during spring-summer (postpartum). Cow LW was lower during autumn, winter and early postpartum (16 days postpartum) in low HA in Year 1 than high HA of Year 1 and high and low HA cows in Year 2. Furthermore, the probability of total pregnancies (0.88 vs 0.59 ± 0.07; P = 0.01) and the calf weight adjusted to 205 days (194 vs 175 ± 16 kg; P < 0.05) were greater in high HA. Calf weight adjusted to 205 days (Year 1: 192 vs Year 2: 177 ± 16 kg; P < 0.05) and survival curves of postpartum anoestrus (P = 0.01) were affected by year but did not affect the probability of conception, early or total pregnancies. In conclusion, the reproductive and productive responses of primiparous beef cows grazing Campos grasslands were improved in high HA and could contribute to alleviating adverse climatic conditions effects.

Body Condition Scores

The body condition score (BCS) in sheep (Ovis aries) is a widely used subjective measure of body condition. Body condition score and liveweight have been reported to be statistically and often linearly related in ewes. Therefore, it was hypothesized that current BCS could be accurately and indirectly predicted using a ewe’s lifetime liveweight, liveweight change, and previous BCS record. Ewes born between 2011 and 2012 (n = 11,798) were followed from 8 months to approximately 67 months of age in New Zealand. Individual ewe data was collected on liveweight and body condition scores at each stage of the annual cycle (pre-breeding, pregnancy diagnosis, pre-lambing, and weaning). Linear regression models were fitted to predict BCS at a given ewe age and stage of the annual cycle using a ewe’s lifetime liveweight records (liveweight alone models). Further, linear models were then fitted using previous BCS and changes in liveweight, in addition to the lifetime liveweight records (combined models). Using the combined models improved (p < 0.01) the R2 value by 39.8% (from 0.32 to 0.45) and lowered the average prediction error by 10% to 12% (from 0.29 to 0.26 body condition scores). However, a significant portion of the variability in BCS remained unaccounted for (39% to 89%) even in the combined models. The procedures found in this study, therefore, may overestimate or underestimate measures by 0.23 to 0.32 BCS, which could substantially change the status of the ewe, leading to incorrect management decisions. However, the findings do still suggest that there is potential for predicting ewe BCS from liveweight using linear regression if the key variables affecting the relationship between BCS and liveweight are accounted for.

The study aimed to compare two diets, Control (CTR) and Experimental (EX) (mainly differing as regards their ingredients, energy, and protein contents) administered to medium and large-sized bitches from two months before the expected proestrus and up to 30 days after delivery on mothers’ weight, body condition score, litter size, milk quality, and puppies’ growth. No differences were found for body weight during pregnancy, even if the BCS after delivery was significantly (p < 0.01) higher in the EX group than in the CTR one. Concerning the size effect, the percentage of weight gain on the initial body weight was double in medium-sized dogs compared to large dogs (p < 0.01). The number of puppies per litter was significantly higher (p < 0.05) for the EX group compared to the CTR one. Concerning puppies’ weight, the CTR group showed a significantly (p < 0.01) higher body weight from the 21st day of life due to the significant (p < 0.01) higher daily weight gain during the suckling period. Considering the performance of bitches and puppies, both diets seem useful for these stages of their lives. In fact, after 30 days of lactation, all tested bitches showed a healthy status and both the percentage of newborns mortality and puppies’ growth kinetics fell into the normal physiological range for the species.

Abstract Future climate predictions suggest greater precipitation events and an increase in mean ambient temperature during winter months, creating wet and muddy conditions during the last third of gestation for spring calving beef cows. Cows housed in these conditions will likely have increased energy requirements; however, there is limited data on cow requirements in such circumstances. The objective of this study was to evaluate the effects of muddy environmental conditions on cow body weight (BW) and body condition score (BCS) in late gestation. Twenty multiparous Angus cows (n = 10/treatment) housed and fed individually were used in this study. Cows were paired based on initial BW, and one cow from each pair was randomly allocated to either the mud (MUD) or control treatment (CON). Cows in the CON treatment were bedded with wood chips and not exposed to mud, while cows in the MUD treatment were housed in mud (23.6 ± 5.8 cm). Cows were fed the same diet, and each pair was fed to the CON cow’s requirements for maintenance and day of gestation. Maintenance requirements were adjusted weekly. From 213 to 269 days of gestation, cows were sampled for BW and BCS weekly. Data were analyzed as a randomized complete block design with repeated measurements, and the SLICE option of SAS was used for mean separation. All cows started at similar BW (P = 0.35) and BCS (P = 0.79); however, cows housed in muddy conditions had lesser BW (P &lt; 0.01) and BCS (P &lt; 0.01) at day 269 compared with CON cows, while there were no dry matter refusals from any animals throughout the study. Therefore, MUD cows weighed 37.6 kg less than CON cows by the end of the study while dry matter intake was the same between treatments, indicating that mud greatly increased cow requirements.

Neutering females may be associated to weight gain in dogs. In order to diagnose possible alterations, such as diabetes and hyperlipidemias, laboratory assessment of carbohydrate and lipid metabolism is important. The aim of this study was to verify glycemia and serum lipid profile in non-spayed and spayed female dogs, and associate these results with the body condition score. Thirty-two spayed (n=16) and non-spayed (n=16) female dogs had their blood collected for biochemical analysis, and were classified as to their body condition score (BCS). Nine had normal BCS, 10 were overweight, and 13 were obese. Little difference was observed among spayed and non-spayed dogs. Glycemia of spayed canine females is higher than that of non-spayed dogs, regardless of the body condition score. Likewise, total cholesterol levels are higher in non-spayed females. The HDL is higher in non-spayed obese dogs than in spayed dogs with the same body condition, this parameter did not differ in other weight groups. Contrary to what happens in post-menopausal women, spaying dogs does not seem to have such a strong effect on the metabolic parameters assessed. This study revealed unique results, where neither spaying nor weight group had a strong association with metabolic alterations.

In this study we test the hypothesis that selecting sheep for a low behavioural reactivity to stressful situations will improve their metabolic efficiency, and thereby feed efficiency, during a controlled trial in an animal house. Twenty-four Merino wethers were used, 12 each from lines selected for high (HBR) and low (LBR) behavioural reactivity to stressful stimuli (human presence and social isolation). The sheep were habituated to the experimental procedures for 10 days, followed by 45 days during which voluntary feed intake was measured so that total daily energy intake was quantified. The sheep were weighed twice weekly before daily feeding. Feed efficiency was determined by measuring net feed intake, average daily weight gain and body condition score. Our hypothesis was not supported by the results of this study. There was no difference between LBR and HBR sheep in average daily weight gain or body condition score. The net feed intake of HBR sheep was lower than that of LBR sheep (P = 0.02), indicating that under the conditions of our experiment, HBR sheep were actually more feed efficient than LBR sheep. This study was carried out on sheep with steady intakes and in familiar surroundings. It is possible that LBR sheep may be more efficient than HBR sheep in more stressful situations.

AbstractThe objective was to determine the effects of avoparcin, bovine somatotropin (bST) and the additive effects of both avoparcin and bST on milk yield, milk composition, live-weight changes and reproduction parameters in post-partum dairy cows. Forty-eight autumn calving cows were allocated using a split-plot within randomized complete-block design to the following treatments: (i) control (2 ml saline plus 1 kg untreated concentrate per day); (ii) avoparcin (2 ml saline plus 1 kg concentrate containing 100 mg avoparin per day); (Hi) bST (25 mg bST in 2 ml saline plus 1 kg untreated concentrate per day); and (iv) avoparcin plus bST (25 mg bST in 2 ml saline plus 1 kg concentrate containing 100 mg avoparcin per day). All injections were given subcutaneously and treatment continued for 84 days beginning 55 (s.e. 4) days after calving. The cows were offered grass silage ad libitum supplemented with 7·2 kg cereal-based concentrates daily. Milk yield and milk composition were measured thrice and once weekly, respectively. The cows were weighed and body condition score was assessed every 2 weeks.Mean daily milk yield of cows assigned to control was 20·1 (s.e. 1·5) kg, avoparcin, 21·5 (s.e. 1·5) kg, bST, 23·9 (s.e. 1·0) kg and avoparcin plus bST, 25·2 (s.e. 1·2) kg over the 84 days of the trial. bST increased milk yield proportionately by 0·18 compared with all cows not given bST (P < 0·01). Avoparcin did not significantly increase milk yield. There was no effect of any treatment on milk composition, body weight or body condition score. None of the experimental treatments had any effect on calving to first service interval, calving to conception interval, number of services per conception or overall conception rate.These results show that in early lactation, avoparcin alone had no effect on production or reproduction parameters in dairy cows; bST alone increased milk yield but did not affect any other production or reproduction parameter. There was no significant additional increase in milk yield when avoparcin and bST were given in combination, compared with bST alone.

Santa Inês

The main objective of this research work was to evaluate the performance of Santa Inês ewes according to their body condition score (BCS) at lambing. Data from 135 adult ewes, with singletons, were used. Ewes were divided into three distinct groups: 1) Bellow average: BCS less than 2.5 points (n = 44); 2) Average: BCS between 2.5 and 3.0 (n = 53); and 3) Above average: BCS greater than 3.0 (n = 38). The scale for BCS varied from 1 (very poor) to 5 (very fat). The individual BW, BCS, metabolic profile, milk production and composition of ewes as well as their lambs’ performance until weaning were considered. Metabolic profile was monitored at -7, +7 and +60 days relative to lambing. It was observed that ewes with higher BCS were also heavier; however, there were no differences among the groups for weights of lambs at birth and weaning (70 days). As there was no difference in milk production and composition, the average daily weight gain of the lambs was also similar for the different BCS groups. The metabolic profile (glucose, ?-hydroxibutyrate, cholesterol, creatinine, urea, hemoglobin, albumin, total protein and aspartate aminotransferase - AST) was also similar among the groups. However, when the metabolic profile was compared among the different physiological stages relative to lambing, some differences were observed. For example, ?-hydroxibutyrate was greater during the peripartum period, and glucose was greater in the lactation phase. As conclusion we could say that even in a situation of poor BCS, Santa Inês ewes have the physiological capacity to adapt themselves to the negative energy balance like those of the periparturient period. It seems that irrespective of the BCS, ewes prioritized lactation and were able to produce enough milk to accordingly nurse their lambs

Zusammenfassung Ziel der Studie war, den Energiebedarf von Warmblutfohlen zu überprüfen, die durch einen Betriebswechsel beim Absetzen erhöhtem Stress ausgesetzt sind. Material und Methoden: Neun Hengstfohlen, die als Absetzer von verschiedenen Züchtern gekauft und gemeinsam aufgestallt wurden, nahmen an der Studie vom Absetzen im Alter von etwa 6 Monaten bis zu einem Alter von etwa 1 Jahr teil. Das Absetzen erfolgte im heimischen Betrieb oder nach gemeinsamem Transport von Stute und Fohlen bei Ankunft im neuen Bestand. Die Fohlen erhielten Heulage (später erster Schnitt), Hafer und Fohlenaufzuchtfutter. Um eine individuelle Kraftfutterzuteilung zu ermöglichen, wurden die Fohlen zweimal täglich separat angebunden. Erhoben wurden die Gesamtaufnahme der Heulage aller Fohlen gemeinsam pro Tag, die tägliche individuelle Kraftfutteraufnahme sowie in 4-wöchigen Abständen Körpermasse und Body Condition Score (BCS). Ergebnisse: Die tägliche Energieaufnahme der Fohlen betrug 74 MJ verdauliche Energie (68 MJ umsetzbare Energie) pro Tier. Die Fohlen wurden mit vergleichsweise niedrigem BCS von 4,2 ± 0,4 (Skala von 1 bis 9) und einer durchschnittlichen Körpermasse von 285 ± 30 kg aufgestallt. Sie erreichten am Ende der Studie im Alter von 319 ± 22 Tagen eine Körpermasse von 326 ± 24 kg und einen BCS von 4,2 ± 0,4. Die Energieaufnahme der Fohlen war höher und ihre Gewichtsentwicklung langsamer als in einer parallel laufenden Studie mit Fohlen, die im Gestüt geboren und aufgewachsen und dementsprechend beim Absetzen weniger Stress ausgesetzt waren. Schlussfolgerung und klinische Relevanz: Fohlen mit relativ niedriger Körpermasse und BCS und erheblichem Stress zum Zeitpunkt des Absetzens benötigen deutlich mehr Energie als Fohlen, die beim Absetzen in ihrer gewohnten Umgebung verbleiben und dadurch weniger Stressoren unterliegen.

Zusammenfassung Gegenstand und Ziel: Gewinn epidemiologischer Daten zur Fütterung von Hunden und Katzen in Deutschland. Material und Methoden: 865 Hundeund 243 Katzenbesitzer wurden anhand standardisierter Fragebögen zu ihrem Tier (Alter, Geschlecht, Gewicht, Ernährungszustand, Gesundheit), dessen Fütterung inklusive Belohnungen und Zusätzen, den Gründen für eine Futterumstellung und zur eigenen Person (Alter, Geschlecht, Schulbildung, Beruf) befragt. Die Befragungen fanden in Tierarztpraxen, Hundeschulen, Tierheimen, Parkanlagen und via Internet statt. Zudem wurde der Body Condition Score (BCS) der Tiere durch ihre Besitzer sowie die Interviewerin beurteilt. Ergebnisse: Das Durchschnittsalter der Hunde lag bei 4,8 Jahren, das der Katzen bei 6,8 Jahren. Das Gewicht reichte beim Hund von 2,2 bis 95 kg, bei der Katze von 2 bis 11 kg. Rund 52% der Hunde und Katzen waren übergewichtig (BCS 6–9). Zwischen der Beurteilung der Besitzer bzw. der Interviewerin gab es Differenzen. Viele Besitzer unterschätzten den BCS und erkannten vor allem beginnendes Übergewicht (BCS 6–7) nicht. 58% der Hundeund 90% der Katzenbesitzer verwendeten ausschließlich handelsübliche Fertigfutter, 35% bzw. knapp 10% kombinierten diese mit zusätzlichen Futtermitteln. Knapp 8% der Hundeund < 1% der Katzenbesitzer verfütterten selbst zubereitete Rationen. Ältere (> 7 Jahre) und kranke Hunde erhielten häufiger selbst hergestellte Rationen. Ältere Besitzer (≥ 46 Jahre) tendierten vermehrt dazu, das Futter selbst zuzubereiten, während die Schulbildung und die Berufstätigkeit keinen Einfluss auf die Fütterung hatten. Ein Zusammenhang zwischen Art der Fütterung und BCS bestand nicht. Besitzer mit geringerer Schulbildung sowie Hausfrauen und Rentner hatten häufiger übergewichtige Tiere. Futterbelohnungen erhielten 95% der Hunde und 65% der Katzen. Ältere und berufstätige Besitzer gaben prozentual seltener Belohnungen. Schlussfolgerungen: Übergewicht ist das größte ernährungsbedingte Problem. Im Vergleich zu früheren Studien hat sich die Zahl übergewichtiger Tiere erhöht. Klinische Relevanz: Tierbesitzer sollten frühzeitig auf Übergewicht hingewiesen werden, da sie den Beginn der Adipositas häufig nicht wahrnehmen. Die meisten Tierbesitzer verabreichen Belohnungen, was bei Diäten berücksichtigt werden muss.
