|
Abstract: The effects of dietary inclusion of Saccharomyces cerevisiae cultureon intake, in vivo digestibility, and fecal nitrogen excretion were examined in dairy buffalo. Forty lactating buffalo cows were equally divided into Control and Saccharomycesgroups, balanced for milk production, parity, and days in milk. Two subsequent 16-d experimental phases were carried out. For both groups during the first experimental period a TMR based on maize silage (maize-TMR) was used, whereas in the second period an alfalfa haylage (alfalfa-TMR) was administered to the animals. In each experimental period, Saccharomyces group was supplemented with 50 g/head/day of yeast (Biocell®, Limena, Padova, Italy), corresponding to 20×109 CFU/head/day Saccharomyces cerevisiae NCYC Sc47 strain. The yeast supplement was top-dressed onto the morning feed. Dry matter intake (DMI) was assessed for 6 consecutive d on group basis, by the difference between feed offered and refused. In the last 3 days of experimental period in vivo digestibility was determined by using acid-insoluble ash (AIA) as an intrinsic digestibility marker. Saccharomyces supplemented buffalo cows presented greater DMI of maize-TMR, whereas no statistical differences between the groups were observed for alfalfa-TMR. Saccharomyces supplementation significantly improved in vivo digestibility of both TMR. Fecal nitrogen excretion was significantly reduced by the use of yeast supplementation. Results suggest that the inclusion of Saccharomyces cerevisiae culture in the diet for lactating buffaloes can be recommended for its effects on cow’s digestive efficiency and fecal nitrogen excretion.

Editor’s Choice : Estimation of Conformation Score in Relation to Body Measurements Using 3D Scanner in Swamp Buffaloes

Abstract: The objective of this study was to develop the appropriate equations to estimate the conformation score both in male and female swamp buffaloes using body part measurements from 3D scanner. The buffaloes’ conformation was evaluated using 3D scanning technique in 72 males and 78 females at Surin, Uthaithanee, Bangkok, Nakornpanom and Sakaew provinces of Thailand. Height (A), heart girth (B), shoulder width (C), iliac width (D), ischial tuberosity width (E), the length between shoulder and ileal wing (F, G), the length between ileal wing to ischial tuberosity (H, I), the length between shoulder to ischial tuberosity (J1, J2), tail length (K), knee circumference (L), the width measuring between the tip (M), the middle (N) and the base of horns (O), the horn length (P) and the length measured from the base to the tip of the horn on the same site (Q) were measured. The results found that A B, D, E, FG, J1J2, L and P were significantly higher along with age in both males and females. The scores obtained currently between academics and the philosophers were closely correlated in every categories in both male and females buffaloes over four and three years of age, respectively, except for the reproductive organ in females. The coefficient of determination (R2) for score prediction in male buffaloes under 4 years old was highest when body length and knee circumference were included in the equation: Score = [(0.568 J1J2) + (1.584 L) – 77.89] (R2 = 0.57, n = 19). The prime factor affecting score in male over 4 years of age was heart girth (R2 = 0.70). However, R2 was rise up to 0.85 when girdle width was included into the equation: Score = [(0.485 B) + (1.892 D) – 156.54] (n = 53). In females under 3 years old, the R2 were low in all type of equation (one traits to four traits equation; 0.25-0.42, n = 21). However, in females over 3 years of age the R2 is high (0.66) when girdle width was included in the equation : Score = [2.655 D – 91.52] (n = 57). Therefore, different traits should be used to evaluate the conformation in immature and mature males and females.

Editor’s Choice : Haematological and Biochemical Characterization of Bubaline Trypanosomosis in Mumbai Region of India

Abstract: The present study was based on observations on 17 cases of Trypanosoma evansi infection in buffaloes diagnosed by blood smear examination. The degree of parasitaemia revealed heavy (64.70%), moderate (23.52%) and mild (11.76%) infections in buffaloes.Haematological analysis revealed subnormal erythrocytic count and haemoglobin in 70.58% buffaloes. Leukocytosis was evident in 70.58% buffaloes with neutrophilia relatively associated with lymphocytopenia.Blood glucose level of 15 hypoglycaemic buffaloes ranged between 27 to 49.05 gm/dl with an average of 39.35 gm/dl. The comparative analysis of the degree of hypoglycaemia with parasitaemia revealed positive correlation between two parameters. Biochemical analysis of sera and blood samples showed increase level of BUN and serum creatinine in 17.64% buffaloes. Keywords: Trypanosoma evansi, Buffaloes, Haematology, Biochemistry. |

Abstract: The study was carried out to compare growth performances of Anatolian and crossbred (Anatolian x Italian) buffalo calves (53 F1, 66 Anatolian, 26 F1xAnatolian) raised at Ilıkpınar Village of Kırıkhan District of Hatay Province. Body measurements were determined in the period of 0-12 months of age. The effects of genotype, sex, birth year effects on each characteristic in each age were investigated using GLM variance analysis. The means of each characteristic in each age for each genotype were calculated. Duncan test was used in comparison of the averages of each characteristic SPSS program was used in the statistical procedures. Genotype created significant variation in live weight at 1 and 6 months of ages respectively and on almost every body measurement almost in every age. Genotype* birth weight, genotype*sex, and genotype*birth year* sex interactions were found statistically significant in the point of view of various characteristics in various ages. Factors had significant effects on various characteristics in various ages. It can be said that, F1 growth was the most speedly and Anatolian buffaloes stayed behind of the other genotypes from the point of view of all the traits.

Abstract: The experiment was conducted using forty two Nili-Ravi lactating buffaloes of Central Institute for Research on Buffaloes, Regional Station-Bir Dosanjh, Nabha, Patiala, Punjab to investigate the effect of heat stress-alleviated conditions on haematological profile in Nili-Ravi buffaloes during hot-dry (HD) and hot-humid (HH) season. All buffaloes were uniformly divided into two groups of twenty one in each group considering their lactation number, stage of lactation, body weight, dam’s milk yield and milk yield in current lactation. Out of which ten buffaloes from each group were selected for blood sampling considering those above factors. The control (T0) group were kept in a separate shed without any extra nutrient supplementation and modification in microclimate and management. The treatment (T1) group was supplemented with niacin@6 gm/buffalo/day, yeast@10 gm/buffalo/day and mustard oil @150gms/buffalo/day. They were provided curtains and mist fans in the shed. Feeding time, frequency and type of ration were also altered. During HD period, T0 group exhibited higher (P<0.002, P<0.05) WBC (17.2 x 109 /L), and lymphocyte (12.52 x 109 /L) counts and lymphocyte per cent (69.46 %) than T1 group (12.32 x 10 9 /L, 7.32 x 10 9 /L and 59.68%, respectively). Similar results were recorded during hot humid season in T0 and T1 group. The neutrophil per cent differed significantly between T0 and T1 group under HD (P<0.001) and HH (P<0.006) season. The study indicated that heat stress during sub-tropical summer months affected the haematology of lactating buffaloes and the stress could be reduced through the change (use of fans and curtains, nutritional supplementations, and feeding alterations together in the form of one package) of microclimate.
