Two alternative remedies for controlling Haemonchus contortus in sheep (pumpkin kernel and garlic) were investigated. The experiment involved 18 4-month-old Merino ram lambs with six lambs per treatment group. The lambs were initially drenched to render them worm free, and then infected with 4000 L3 H. contortus larvae, 2 weeks later. Four weeks after infection, faecal egg counts were performed and lambs were allocated into treatment groups and fed their respective diets (control, pumpkin kernel or garlic) for 2 weeks. The lambs were combined into a single group grazing pasture for the last week of the experiment. Faecal worm egg counts (WEC) were carried out weekly for 3 weeks following allocation to treatment diets. Clinical signs of infection observed included liveweight, body condition score and voluntary feed intake. The pumpkin kernel treatment resulted in a 65.5% decrease in the initial level of WEC, but this increased back to the initial level as soon as animals came off treatment. The garlic resulted in a 64.4% decrease in WEC from the initial level and this increased slightly (to 25.5% of the initial level and 43.5% lower than the control) when the animals came off treatment, suggesting that there was a residual effect of the garlic and/or that the garlic had an effect beyond decreasing the fecundity of the parasites. There was no significant difference (P > 0.05) between treatments in liveweight, body condition score or voluntary feed intake. Throughout the experiment voluntary feed intake and liveweight increased while body condition scores remained stable. We concluded that pumpkin kernel and garlic show potential for parasite control by affecting the fecundity of the parasites. Our results also indicate that with good nutrition lambs can cope with high parasite burdens and still be productive during the early stages of infection.

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.

The objective of this study was to investigate to what extent fertility and lambing season of fat-tailed ewes raised under an extensive production system are related to liveweight, body condition and changes around mating. Ewe liveweight and body condition score (BSC) were recorded in June, July and August over a period of 3 years (1999–2001) in 11 flocks (eight flocks of Kurdi breed and three flocks of Kurdi × Sanjabi crossbred). Both Kurdi and Sanjabi are native fat-tailed breeds in western Iran. In total, 3278 lambing records relating to 1592 ewes and data on mating date, liveweight and BCS of 1930 ewes (3975 records) were used for statistical analyses. The statistical model for bodyweight and body condition data included fixed effects of breed group, flock nested within breed group, year, the future lambing status following summer breeding (barren, autumn lambing and winter lambing), ewe age and all two-way interactions. Breed group had a significant effect on ewe liveweight (P < 0.01). However, there was no significant difference between BCS of the two breed groups around mating. Ewe liveweights measured in June, July and August had significant effects on fertility and lambing season (P < 0.01). Ewes that produced lambs were generally heavier at mating than barren ewes (P < 0.01). Autumn-lambing ewes were heavier than winter-lambing ewes in June and July (P < 0.01). Effects of changes in liveweight on fertility and lambing season were significant (P < 0.01). The effects of BCS in June, July and August (P < 0.01) and changes in BCS during the mating period (P < 0.05) on fertility and lambing season were also significant. The mean BCS (in June and July) of autumn-lambing ewes was greater than that of the winter-lambing and barren ewes (P < 0.05). The proportion of autumn-lambing ewes significantly increased as BCS in July increased, whereas the proportion of barren ewes decreased (P < 0.01). Fertility was associated with age so that as the age of the ewes increased from 2 to 7 years, the proportion of barren ewes significantly decreased from 29 to 5% (P < 0.01). There was a relatively high proportion of very thin ewes of 2 and 3 years of age. These findings imply that low body condition is a particular problem in younger ewes suggesting the importance of giving special nutritional treatment to younger ewes to reduce the proportion of barren ewes.

AbstractThe overall objective of a series of experiments to investigate ‘metabolic stress’ was to examine the relationships between ‘metabolic load’, disease and other parameters associated with the welfare of the dairy cow. In the main, these used several well controlled herd based studies complimented with more basic and strategic investigations. In this paper we compare and contrast practical aspects of health and welfare in two high genetic merit herds managed at the extremes of inputs and outputs for dairy farming in south-west Scotland. The hypothesis was that high output herds would have more health and welfare problems than low input herds. Two herds (70 Holstein-Friesian cows each) at SAC Acrehead Dumfries of a similar genetic background (overall in the top 5% of UK cows by PIN and ITEM), were housed in identical buildings and tended by the same herdsman. Both herds had autumn- and spring-calving cattle. The ‘low input’ herd (LI) was given a minimum of concentrate (approx. 0.5 t per cow per year) and milked twice a day and had a restricted quota of 385 000 l. The ‘high output’ herd (HO) was managed for high yields (unrestricted quota) and was given concentrates (2 t per cow per year) and forage ad libitum and milked three times daily. In 1995-96 the sole source of winter forage was grass/clover silage (LI) or grass silage (HO) but in 1996-1998 ensiled cereal and fodder beet were included in both diets. ‘Metabolic load’ could only be inferred from overall inputs, milk outputs, weight loss, body condition score and behaviour. There were significant differences in 305-day lactation yields between herds, and season of calving especially in 1995-96 (LI autumn; 5952 l at 30 g/kg protein (P); LI spring; 5741 l, 32.5 g/kg P; HO autumn; 9541 l at 32.8 g/kg P; HO spring; 8402 l, 32.6 g/kg P). LI weight and body condition-score losses were greatest in this year and behavioural studies showed substantial differences in feeding time (HO < LI, P < 0.05) and total lying time (LI < HO; P < 0.05). However these differences were much less marked in subsequent years. There was a significant difference in the prevalence and incidence of clinical lameness between herds (HO > LI; P < 0.05) and season (autumn > spring P < 0.05) but not for mastitis or metabolic disease. An in-depth study of subclinical claw horn lesion development in first calving heifers showed significant differences between herds in 1996-97 (LI > HO, P < 0.05) but none in 1995-96. There was a significant difference for season in both years (autumn > spring, P < 0.05). Analysis of blood biochemistry parameters of samples taken at approximately 1 month after calving showed some significant differences between LI and HO generally indicating a greater ‘metabolic load’ for LI. Although the full effects of ‘metabolic load’ on immune function and reproduction are dealt with elsewhere our preliminary data showed no significant differences between herds for the former but some significant differences for the latter, in particular there were differences in aspects of the progesterone profiles between herds and more importantly between seasons. However these latter differences were not clearly reflected in conception rates. It was concluded that the hypothesis was not fully sustained and that both systems had pitfalls in terms of welfare. The three major areas causing difficulties for both systems were the need first to ensure adequate intake of forage; secondly to limit the environmental challenge to the feet and udder and finally to marry these systems to the factors limiting reproduction, primarily calving season and ability of reproduction management.

A research work was undertaken to evaluate the feeding effects of di-calcium phosphate (DCP) on calcium balance and body condition score of dairy cows fed Napier grass. The trial was conducted in the village Alokdiar of Shajadpur upazilla under Sirajgonj district. Twenty crossbred lactating dairy cows of 320 ±15.5 kg live weight were used for the trial. Animals were equally and randomly allocated into four groups, T0 (Napier+concentrate), T1 (Napier+concentrate+100g DCP), T2 (Napier+concentrate+150g DCP) and T3 (Napier+concentrate+200g DCP). Total DMI did not differ significantly (p>0.05) among the groups but highly significant differences (p<0.01) were found in Ca intake. Ca balance; and Ca in feces, Ca in urine, Ca in milk and total Ca excretion differed significantly (p<0.05). No significant  difference (p>0.05) was found in DM in feces (%), DM in feces (kg/d) and milk production (L) among the treatment groups except urine excretion. There was a linear increase of body condition score (BCS) with DCP (T1, T2 and T3), but BCS was linearly declined in non DCP diet (T0). Diets with 150g DCP may be suggested for optimizing Calcium balance and body condition score of dairy cows fed Napier grasses.DOI: http://dx.doi.org/10.3329/bjas.v43i3.21648 Bang. J. Anim.

ABSTRACT: Feline sporotrichosis is a relevant mycose in veterinary medicine due to its severity and zoonotic potential and the fact that it can be difficult to treat. The immune status of the animal exerts influence on the prognosis of the disease and determines its clinical outcome. This study evaluated the efficacy of the immunomodulatory thymomodulin as an adjunct to antifungal therapy in cats with disseminated sporotrichosis; thymomodulin was used in association with itraconazole (ITL) and potassium iodide (KI) to treat this fungal disease in the feline patient. Thirty-one cats (n=31) diagnosed with disseminated cutaneous sporotrichosis were divided into two groups as follows: Group 1 (G1) (n=16), which included those animals that were treated with thymomodulin in association with ITL and KI, and Group 2 (G2) (n=15) which had pacientsthat received ITL and KI only. The response to different treatment modalities was assessed, considering the survival rate, time frame for the lesions to respond to therapy, and clinical improvement or deterioration according to a body condition score system. Animals from G1 had a survival rate of nearly 100% (93.6%) that was approximately twice higher than the survival rate of those animals from G2 (53%). Moreover, patients from G1 had a significantly better prognosis, improved body condition, and shorter time for remission of the extra cutaneous clinical signs (p<0.02). Our findings showed that the association of thymomodulin with ITL and KI improves the prognosis of cats with disseminated cutaneous sporotrichosis.

Mastitis is an inflammation of the mammary gland that can be classified as clinical and subclinical mastitis. The clinical mastitis can be diagnosed based on clinical signs, whilst subclinical mastitis mostly through somatic cell count (SCC). This study was carried out to determine the subclinical mastitis effects on live weight, body condition score (BCS) and external udder traits of Dorper sheep. A total 16 Dorper ewes were selected and screened for mastitis using the Californian mastitis test (CMT). The live weight, BCS and external udder traits (i.e. udder length (UL), udder width (UW), rear udder depth (RUD), cistern depth (CD) and teat length (TL) of the ewes were measured. The subclinical mastitis did not affect the live weight and BCS of Dorper ewes. Whilst for external udder measurements; the highest average of udder length, udder width, rear udder depth and cistern depth were indicated in CMT score as strong positive which shows that the measurement values of external ewes’ udder are increased when the strength detection of CMT scores increased and vice versa. However, all of the external udder parameters measured were not statistically (P>0.05) affected by the mastitis infection scores. The present results indicate that live weight, BCS and all external udder parameters did not influence the subclinical mastitis detected in the milk’s samples of the ewes. This study suggests that subclinical mastitis does not directly affected by morphology alteration of external udder traits, live weight or BCS, however it is likely affect the quality of milk produced.

Abstract Background: Lungworms are parasitic nematode round worms that infest the lungs of ruminants. The infections have wide distribution in the world including Ethiopia. Epidemiological distribution of lung worm depends more on pasture contamination by carrier animals. Diagnosis is based on clinical signs, postmortem findings and laboratory testing (detecting lungworm larvae in faces). The aims of this study were to determine the current prevalence, identifying the species and assess the possible risk factors of lung worm infection in cattle and sheep at Gondar Elfora abattoir.Result: Out of 500 animals (240 cattle and 260 sheep) both coprological and postmortem examination were conducted. The overall occurrence of lungworm infection in both cattle and sheep were 3.75% and 7.31% respectively. The prevalence of lung worm in cattle and sheep in ante mortem inspection with respiratory problem was 8.00% and 19.51% respectively. Coprological prevalence of infection: in young and adult age groups of cattle was 7.04% and 2.37% and in sheep 6.8% and 7.9% respectively. With regard to body condition (poor, medium and good) having the prevalence of 13.64%, 3.3% and 0.00% in cattle and 16.2%, 5.35% and 7.33% in sheep respectively. It has significant difference with body condition score of cattle and sheep (p<0.05 The occurrence of identified lung worm in cattle was Dictyocaulus viviparous (3.75%); in sheep Dictyocaulus filaria (52.63%) higher than Muellerius capillaries (36.84%) followed by Protostrongylus rufescens(10.53%). Over all prevalence in cattle and sheep were 1.67% and 8.08% respectively. Finding with respect to young and adult age groups of cattle was 4.23%, 0.59%, and in sheep 7.48% and 8.85%. The identified lung worm species in sheep, mixed infection (42.85%) was higher than Dictyocaulus filarial (28.57%) followed by Muellerius capillaries (19.05%) and Protostrongylus rufescens (9.52%). Conclusions: Generally lungworm infection has a great effect on animal health and production. It needs emphasis to prevent and control to overcome this problem.

With the increased incidence of parasite resistance to chemical anthelmintics worldwide novel approaches to manage parasite infection, such as medicinal plants and their extracts, are being investigated by the scientific community. The current study tested the effect of three rates of garlic (0.9, 1.8 and 3.6%) in a pelleted ration on Haemonchus contortus in sheep. Thirty-nine Merino wether lambs aged 6 months were divided into five treatment groups, including three garlic dose rates and two control groups that received no garlic. All animals were infected with 4000 L3 H. contortus larvae 3 weeks after allocation to treatments. A positive control group was drenched with abamectin 28 days after infection. The synthetic drench was effective in controlling the parasites, but there was no reduction in either worm egg counts (WEC) or total worm count due to the garlic. The 3.6% garlic treatment had significantly lower (P < 0.05) liveweight, feed intake, body condition score and feed conversion ratio than any of the other treatment groups, suggesting that this level of garlic had a low level of anti-nutritional properties. There was an interaction between faecal WEC and voluntary feed intake over time, with the animals with higher voluntary feed intake having lower WEC over time.

Fasciola, Fascioloides, and Dicrocoelium cause liver fluke diseases in ruminants and are of zoonotic and economic importance. This cross-sectional study aimed to determine the prevalence of liver fluke egg infection in White Fulani Cattle slaughtered in Wukari Cattle market abattoir in Wukari, Taraba State. A total of 262 gallbladders were collected and their contents were analyzed for the presence of eggs of liver flukes using sedimentation technique. Descriptive analysis was done using SPSS version 20 for window and Pearson’s Chi-Square (χ2) was used to evaluate the association between variables. Fasciola and Dicrocoelium eggs were encountered. Only 74 (28.2%) samples were positive for Fasciola egg and 211 (80.5%) for Dicrocoelium. The prevalence of liver fluke infection revealed 25% and 28.6% Fasciola eggs for male and female animals, respectively, while lancet fluke had 83.3% for male and 80.3% for female. Fasciola eggs were recovered in 20.8% of animals aged less 3 years (<3yrs) and 29.9% was recorded in animals 3 years and above (≥ 3yrs) while 81.3% for animals ≥ 3yrs and 77.1% for animals <3yrs were recorded for Dicrocoelium eggs. The body condition score-based prevalence for Fasciola yielded 38.1%, 26.8%, and 14% for poor, average, and good, respectively, while Dicrocoelium yielded 85.7%, 79.3%, and 85.7%. There was a significant difference between the body condition scores for fasciolosis. Only 59% harboured single infection with eggs of Dicrocoelium (P< 0.05) while 6.9% harboured Fasciola eggs. Mixed infection associating Fasciola and Dicrocoelium was observed in 21.4% of the sample cattle. Liver fluke infections: fasciolosis and dicrocoeliosis occur among White Fulani cattle in Wukari and these infections are associated with the body condition score of the animals. This greatly affects the cattle production. There is a need to institute adequate control programmes complemented with good well-planned management practices in any production system involving cattle in Wukari.

The present study was carried out to assess the effect of different farming systems on productive performance, body condition score and carcass characteristics of Deccani lambs. Thirty-six weaned lambs having 3 months of age were divided into three groups with twelve lambs in each group in under intensive (T1), semi-intensive (T2) and extensive (T3) farming systems. The comparative mean dry matter intake (kg/day) and (kg/100kg BW) was significantly (p less than 0.05) higher in T1 group when compared to other groups. T2 group had significantly (p less than 0.05) higher DM intake (kg/day) than T3 group. The mean values of Average daily gains in Deccani lambs were significantly (p less than 0.05) higher in T1 group compared to T2 and T3 groups. The feed efficiency was significantly (p less than 0.05) higher in T1 compared to T2, T3 groups. Statistically significant difference was found in BCS at six months of age (p less than 0.05) between T1 and T3 groups. BCS at 9, 12 months and overall BCS, there was a significant (p less than 0.05) difference between T1 and T3 groups. T1 group had higher pre-slaughter weight, hot carcass weight, meat %, fat% and meat: bone ratio thanT2 and T3. The dressing yields were comparable. The weights of other offals (heart, kidney, spleen, testicles, blood, head and lung and trachea) were comparable. The findings of this study indicated that the intensive and semi-intensive system of rearing could be useful for mutton production. In extensive system, which is predominant in India should change its facet by enriching the grazing land resources as well by the supplementation of required plane of nutrition during growth and special life stages viz., gestation, puberty, post lambing and finisher stages for achieving optimum productivity.
