Risk factors associated with subclinical mastitis in dairy cows reared in district Ganderbal, Jammu and Kashmir

Subclinical mastitis is associated with certain risk factors such as age, lactation stage, milk production and parity. A cross sectional study including 135 cross bred Holstein Friesian dairy cows was undertaken from June 2017 to January 2019 in surrounding villages of district Ganderbal in order to identify major risk factors. The overall prevalence of SCM was 81.48%. The highest prevalence of subclinical mastitis associated with various risk factors was 48.1% (early lactation), 44.54% (5-7 years), 49.09% (>10 litres per day) and 30.90% (3rd parity) respectively. In intensive system of rearing, prevalence was 66.36% whereas in extensive 33.63% was found. In present study, single quarter was affected in 61.81% of SCM infections. In milking method, knuckling and stripping showed more incidence of SCM. In present study, moderate form of mastitis was more predominant (40.9%).

Performance of female Bali cattle in different management systems at Field Station of Sekolah Peternakan Rakyat (SL-SPR) Kuamang Abadi

This study aims to evaluate the performance of Bali cows in different management systems in the Field Station of Sekolah Peternakan Rakyat (SL-SPR) Kuamang Abadi. The linear body measurement and reproductive performances of one hundred twenty-six Bali cows owned by 64 farmers located in 4 villages in SL-SPR Kuamang Abadi were measured and recorded. Survey and observation were done from October to November 2020. Data were analyzed using statistical and descriptive methods. The parameters of linear body measurement included chest circle (CC), body length (BL), and body height (BH). The reproductive performance included age first calving (AFC), calving interval (CI), days open (DO), and service per conception (S/C). The result of linear body measurement showed that the largest CC was in a semi-intensive system at 158,03 cm; the largest BL and BH in the intensive system were 119,35 cm and 111,2 cm, respectively. The result of the reproductive performance showed that cattle in the semi-intensive systems had lower averages AFC, CI, DO, and S/C, i.e., 958,7 days, 375,1 days, 90,1 days, and 1,7, respectively. The results obtained can be used as the basis for improving maintenance management and the development of breeding Bali cattle in SL-SPR Kuamang Abadi.

Epidemiology of Cryptosporidium sp. infection among free-range and intensive farm birds in Akure South LGA, Ondo State, Nigeria

Background Cryptosporidium spp. is an intracellular zoonotic protozoan parasite that causes cryptosporidiosis, a diarrhoeal disease of humans and domestic animals. Transmission of Cryptosporidiosis to humans and other animals is by ingestion of oocysts of the parasite and as low as ten oocysts can cause clinical infections in otherwise healthy persons. The aim of this study is to investigate the prevalence of Cryptosporidiosis and compare the rate of infection between free range bird and poultry bird reared in Akure South LGA, Ondo State, Nigeria. Result The overall prevalence of Cryptosporidium reported in this study was 11.9%. Free-range birds show a higher prevalence rate 13.2% of Cryptosporidium oocysts than 10.9% in poultry birds. Aule recorded the highest prevalence of Cryptosporidium oocysts infection (16.1%) followed by Ipinsa (12.2%), Onigari (10%), and FUTA (8.1%). The highest prevalence 15.9% was recorded in broilers, while turkey showed no infection (0%) by Cryptosporidium. Semi-intensive system of farming was showed to be more susceptible to Cryptosporidium oocysts infection at 13.3% followed by the 12.6%, 10.3% in deep litter and battery cage. The female birds recorded higher Cryptosporidium oocysts infection (12.2%) than the male (11.6%). Conclusion The study established the presence of Cryptosporidium oocysts infection among studied birds in Akure South LG of Ondo State, Nigeria.

PSVIII-12 An economic and emergy approach to evaluate the level of sustainability of lamb production: A case study in Brazil

This study employed the Economic Theory (ET) to calculate the production costs and the Emergy Methodology (EM) to identify the contributions of nature and economy of lambs produced in an intensive system located in Cravinhos city, State of São Paulo. In addition, was employed Emergy Methodology (EM) to identify the contributions of nature and economy in the system. The adopted scheme of cost allocation followed the classification according to ET, under Variable Cost (VC), Operational Fixed Cost (FC), Opportunity Costs of land and capital (OC), and Total Cost (TC). The EM manages to quantify all the resources used in the system in Contributions from Nature (I) and Feedback from the economy (F). The I originate from the Sum of Renewable (R) and Non-renewable (N) local resources, while that F is composed of the Materials (M) and Services (S) from the economic system. We found that to produce 935 lambs per year the TC was US$ 96,021.08. VC represented 19.08% of TC, while 76.6% were represented by FC, and 4.3% by the IF. The cost produced per animal and kg of live weight was US$ 72.73 and US$ 1.82, respectively. On the other hand, the total energy flow (Y) required by the system was 3.05E+16 seJ/yr (Solar Joules per year) for produce (Ep) 1.68E+06J/yr (Joules per year). Y was represented in a 53.92% by I (7.98% for R, from the sun, rain, and wind; and 45.94% for N, from the soil loss and groundwater), and 46,08% by F (27.8% for M, from the feed, minerals, steel, fueled, etc. and 10.7% for S, from manpower, other services external, taxes, etc.). These results show that the studied system has a %Renewability (%R = R / Y) of 7.98%. Thus, we can conclude that the system depends on 92.02% of resources from non-renewable sources.

​Management Practices Adopted by Farmers of Budgam in Rearing Kashmir Merino

Background: Kashmir Merino is a very important synthetic sheep breed of J and K. It is widely adopted across the Valley. It is an important source of income for the poor and marginalized farmers. An attempt was made to understand the management practices adopted by farmers of Budgam in rearing of Kashmir Merino sheep. Methods: A survey was undertaken in Budgam district understand the management practices used by farmers for rearing Kashmir Merino sheep. Result: Majority of the sheep farmers (68.42) housed Kashmir Merino sheep in Pucca house made of brick structures reinforced with either cement or mud whereas only (31.58%) housed sheep in Katcha houses. Breeding season ranges from April to May and August to December. Majority of the respondents (75.00%) reported autumn season as the main breeding season and only 25% reported spring as main breeding season. The sheep farmer was either having in possession small or marginal land holding. Sheep were reared on semi-intensive feeding systems during early spring and late autumn, intensive system during winter from December to April and extensive system from May to November. The vaccination against infectious diseases, dozing against prevalent parasites and treatment as per morbidity was carried out by expert veterinarians of Department of sheep Husbandry. Poor economic and low technical proficiency are main hurdles for farmers of Budgam to have good housing facilities to manage the breed. Management has significant effect on performance of sheep.

An Important Genotype for Sustainable Extensive Goat Production Systems of Turkey: The Gökçeada Goat

In this study, it was aimed to report some traits of Gökçeada goats, which raised under the natural conditions of Gökçeada, with respect to their protection within the scope of genetic resources. In this respect the information obtained from the goats supplied from the Island and reared in a semi-intensive system at Çanakkale Onsekiz Mart University and also the information obtained from the literature were collected and the biological and zootechnical identifications of the Gökçeada goat were performed. Gökçeada goats, which are predominantly black, have yellow or red blazes on both sides of their heads including their eyes. It was seen that Gökçeada goats had similar body measurements and lower live weights as compared to those of the same species on the mainland. The birth weight and the mature live weight of Gökçeada goats were found as 2.55 kg and 38 kg, respectively, whereas their mean kid yield per goat at birth was determined as 1.6 to 1.8 kids. Individuals with a milk yield of 591 kg were striking in the Gökçeada genotype, in which the mean lactation length and the mean lactation milk yield were determined as 251 to 259 days and 227 to 245 kg, respectively. Its milk fat (4.92-5.75%) and milk protein (3.29%) resembled those of our other native breeds. It is necessary to reveal, with more elaborate studies, the potential for Gökçeada goat cheese that is greatly demanded on the Island. It was determined that the Gökçeada kids, which were considered as dairy kids, had some small but nonfat carcass and that their meat was soft and of a light color and had a slight smell. One should be careful about the adaptation of the Gökçeada genotype, which successfully maintains itself under the island conditions and which is the source of income for producers, to intensive and extensive goat production systems.

Determination of factors affecting milk yield, composition and udder morphometry of Hair and cross-bred dairy goats in a semi-intensive system

In this Research Communication we report milk yield, milk composition and udder morphometry of Hair, Alpine × Hair F1 (AHF1), and Saanen × Hair F1 (SHF1) cross-bred goat genotypes managed in a semi-intensive system. The SHF1 genotype had significantly higher lactation milk yield, fat yield, protein yield, and electrical conductivity than other genotypes, whilst AHF1 was intermediate. The milk fat, protein, lactose, solids-non-fat and total solids contents as well as pH and density of the Hair goat milk were significantly higher than the corresponding values of the cross-bred genotypes. The highest correlation amongst udder characteristics and production was between lactation milk yield and udder volume (P < 0.01; r = from 0.63 to 0.77). The results of this study suggest that crossbreeding can have a positive effect on the milk production characteristics of local goats, thereby reducing the pressure on the ecosystem, and suggest that udder measurements, especially volume, can be a helpful tool for estimating milk yield.
